An on-grid solar system, also known as a grid-tied solar system, is when solar panels are put in and connected to the main power grid. Extra electricity made by the panels is sent to the grid when you don’t need it all. When the solar power isn’t enough, you get power from the grid. It usually doesn’t need battery storage and depends on the grid for a balance.
Most governments require a maximum power of 800w. Power greater than this needs to be approved.
Therefore, the power options of an on-grid solar system ranging from 600W to 800W are the most popular. They typically require 2 solar panels of 450W each.

Most governments require a maximum power of 800w. A power greater than this needs to be approved. Therefore, the power options of an on-grid solar system ranging from 600W to 800W are the most popular.
The main purpose of the micro-inverter is to use solar energy to charge the power grid to achieve cost savings and all-weather power supply.
However, the government has restrictions on household charging, usually allowing only 800W of charging capacity. Therefore, micro-inverters usually do not directly connect to AC loads, but convert DC power into AC power first and then connect to the power grid or other systems for distribution and use. Connecting to the power grid can achieve unified distribution and optimized utilization of electrical energy.
Different to the off-grid system, the on-grid system needs to interact closely with the power grid. So micro inverter forms a better choice than the normal one:
Stability: Micro inverters can better adapt to the requirements of the power grid, providing more stable and high-quality power.
Reliability: The overall reliability of micro-inverters is relatively high. If a micro-inverter fails, it usually affects the corresponding solar panel only, and the other parts can still work normally. In comparison, if the inverter of the off-grid system fails, it may cause the entire off-grid system to stop power supply. If it is applied in the on-grid system, it will be very dangerous.
Flexibility: The small size of micro-inverters is an advantage that makes them more flexible and convenient during installation, and they can adapt to various installation environments and space limitations. Especially in places with limited space, such as roofs with irregular shapes, obstacles, or small installation areas, the small size of micro-inverters helps to utilize the space more effectively and increase the layout density of solar panels.
On the other hand, the stability, reliability, and flexibility of micro-inverters lead to their complex structure, which also means higher costs.
Stand-alone micro inverter usually works independently and does not directly connect to other boards, and the power output is relatively low.
Parallelmicro inverter can connect multiple boards through a specific connection method (such as male and female plugs) to work collaboratively, thereby increasing the total output power. The number of connections can be flexibly selected to adjust the total power and system configuration.
The input interface connects to the solar panel, with the PV+ connected by a red wire and the PV- connected by a black wire. It can typically match solar panels with a power of 1 – 1.5 times (1.2 – 1.3 times is the best) to prevent energy loss. (same as off-grid inverter)
The output interface can directly connect to AC loads, and some also have antennas that can be connected to mobile phones via WiFi to view electricity consumption.
The working principle of an off-grid system is that:
Solar panels capture sunlight and convert it into direct current (DC) electricity.
This DC power then passes through a charge controller, which regulates the charging process and protects the batteries from overcharging.
The batteries store the electricity for later use.
When there is an electricity demand, the stored DC power is sent to an inverter, which converts it into alternating current (AC) that can be used to power various electrical appliances and devices.
For farms and agricultural buildings in isolated areas
For facilities in remote regions, such as communication towers or remote research stations in deserts, mountains that have no access to the main grid, etc.
It depends on the amount of power you require. Generally, each solar panel represents 560w.
The power options of an off-grid solar system ranging from 3kw to 8kw are the most popular. They typically need 5 to 14 pieces of solar panels, specifically:
Voltage regulation: Monitor the input voltage (such as from the solar panel) and stabilize it within a certain range to ensure that the voltage output to the load or battery meets the requirements.
Current control: Control the current magnitude to prevent excessive current from causing damage to the system while ensuring the normal operation of the equipment.
Overcharge and over-discharge protection: Monitor the charging state of the battery to prevent excessive charging or discharging of the battery to extend its service life.
Power distribution: Allocate power reasonably according to the demand of the load and the supply of the power source to ensure the stable operation of the system.
Reverse polarity protection: Prevent the reverse polarity of the power source to protect the circuit and equipment from damage. For example, in some simple off-grid solar power generation systems, if the load has low requirements for changes in the power frequency and rotational speed, the controller may mainly focus on the above basic voltage, current, and protection functions to achieve a relatively simple but effective energy management.
PWM controllers are cost-effective and work by modulating the pulse width.
MPPT controllers can track the maximum power point of the solar panel in real-time to ensure maximum energy output from the solar panel. Therefore, they are usually more efficient, can provide faster and more stable charging. At the same time, MPPT can accept a wider range of input voltages and convert them efficiently to voltages suitable for battery charging. However, due to more complex technology, the cost is usually higher.
Therefore, if the efficiency and performance requirements of the solar power generation system are high, especially in unstable lighting conditions or when it is desired to make more full use of the energy of the solar panel, the MPPT controller is a better choice; if the budget is limited and the performance requirements of the system are not particularly demanding, the PWM controller can also meet the basic needs.
Some controllers, in pursuit of higher performance, have built-in frequency converters, and their working methods are relatively more complex and intelligent:
Precise speed regulation: According to changes in the input power (such as changes in solar intensity), precisely adjust the rotational speed of the equipment to achieve the best operating efficiency and energy-saving effect.
Optimize power output: Monitor and adjust the power output in real-time to keep the system operating efficiently under different working conditions and maximize energy utilization. Adapt to load changes: Be able to respond quickly to load changes, automatically adjust the output frequency and voltage to ensure the stability and reliability of the system.
Improve energy utilization rate: Continuously search for the best operating point (maximum power point) to effectively improve the utilization rate of solar and other energies.
Intelligent control: Can communicate and collaborate with other intelligent devices or systems to implement more complex control strategies and functions.
The input interface connects to the solar panel, with the PV+ connected by a red wire and the PV- connected by a black wire. It can typically match solar panels with a power of 1 – 1.5 times (1.2 – 1.3 times is the best) to prevent energy loss.
The output interface can directly connect to DC loads, such as DC bulbs, water pumps, air conditioners, fans, etc., and can also charge the battery.
The working principle of the off-grid inverter is to convert DC power into AC power.
The inverter usually contains electronic switching components, such as transistor IGBT. By controlling the rapid on-off of these switching components, the input DC power is chopped into a series of pulses. To obtain smooth AC power output, the inverter usually also uses a filter circuit to reduce the harmonic components in the output voltage and current to make it closer to a sine wave. In short, the inverter realizes the conversion from DC to AC through high-speed switching control and filtering processing of the DC power.
VFD (Variable Frequency Drive) is a special type of inverter, who have a frequency conversion function and can flexibly change the output AC frequency and voltage according to actual needs. This makes it widely used in fields such as motor speed control. By adjusting the frequency and voltage, the rotational speed of the motor can be precisely controlled to achieve energy saving, improve operating efficiency, and meet the needs of different working conditions. For example, in industrial production equipment such as fans and water pumps, the rotational speed can be automatically adjusted according to load changes to achieve energy saving purposes.
Inverters only convert DC power into AC power with a fixed frequency and voltage but do not change the frequency. They are usually used in some devices with low requirements for changes in power frequency and voltage, such as converting the DC power generated by solar panels into the commonly used 220V, 50Hz AC power in households to supply power to general household appliances.
On-grid solar systems are usually a more cost-effective choice, as they allow you to save money on your electricity bill and potentially earn credits. They also don’t require expensive battery banks like off-grid systems do.
Off-grid solar systems offer independence from the power grid, which can be beneficial in remote areas or during power outages.
The first type can handle both off-grid and on-grid operations simultaneously. The output interface can be connected to sell any extra energy to the grid.
The second type is an off-grid solar system combined with an energy source from the grid. However, the output interface of this type cannot be connected to sell any extra energy to the grid.
Most of the products available in the market are of the second type.
The solar panels convert sunlight into direct current (DC) electricity.
The hybrid inverter then changes this DC power into alternating current (AC), which is the type of electricity used in most devices and the grid.
When the solar power produced is more than the immediate demand, the excess electricity can be stored in batteries for later use.
If solar power is not enough to meet the current electricity needs, the system will draw power from the main power grid or the stored energy in batteries.
The controller (usually inside of the hybrid inverter) continuously monitors power production and consumption and manages the power flow from different sources to guarantee a reliable and continuous supply of electricity.
It depends on the amount of power you require. Generally, each solar panel represents 560w.
The power options of a hybrid solar system ranging from 5kw to 10kw are the most popular. They typically need 10 to 20 pieces of solar panels, specifically:
5kw: 10 pieces
8kw: 16 pieces
10kw: 20 pieces
You can obtain tailored combinations and quantities of solar panels by contacting us.
The hybrid inverter is an electrical conversion device that can handle both off-grid and on-grid functions:
During off-grid operation, when the power grid is down, the hybrid inverter uses the power from the battery or solar panels to supply power to each loads, achieving independent power supply.
During on-grid operation, when the power grid is normal, it can feed back the excess solar power to the power grid, saving electricity costs and generating revenue.
The input interface can receive both DC power from solar panels and AC power from the power grid, flexibly utilizing different energy sources for optimization.
The output interface can convert DC power into AC power to meet the needs of AC loads, and can also convert AC power into DC power to charge the battery or supply DC loads.
Off-grid solar systems are ideal if you are in a location with no access to the main power grid. It provides power solely based on the solar panels and any attached battery storage. However, it often requires a significant investment in batteries and may have limitations in providing continuous high-power output.
Hybrid solar systems are suitable for those who have a reliable grid connection and want to balance costs, as they combine the benefits of solar power with the option to draw from the grid or other backup sources when needed. You don’t need as large of a battery storage capacity compared to a pure off-grid system.
A balcony system is a solar on-grid system built on the balcony. Solar panels (and batteries in some cases) on the balcony can create a charging station for electronics to meet basic energy needs. It can be used for various home devices, and surplus energy goes to the city power grid if not consumed.
Yes, but it depends on the size and orientation of your balcony. Ensure that you install the solar panels on the right side where sunlight can reach. There are several sizes and types of panels. You can select an appropriate one for your balcony.
The working principle of the Balcony Solar System depends on 2 parts: solar panel and inverter.
1) Solar Panel:
The balcony solar system primarily relies on high-quality solar panels strategically installed on the balcony to capture sunlight. These solar panels are composed of an array of photovoltaic cells, which are engineered to efficiently absorb photons from sunlight.
When sunlight reaches the photovoltaic cells, a chemical reaction takes place within them. This reaction causes electrons to be released and start flowing, converting the incoming light energy into direct current (DC) electricity. The DC electricity produced by the solar panels is then transmitted to the inverter.
The inverter is a crucial component that functions to transform the DC electricity into alternating current (AC) electricity.
Once the conversion to AC electricity is complete, there are two possible paths.
Firstly, the AC electricity can be fed into the home power grid. This allows for storage and potential distribution within the larger electrical network of the home.
Secondly, the AC electricity can directly power various AC loads within the household, such as appliances, lights, and electronic devices. This immediate usage ensures that the energy generated from the solar panels is put to practical and useful applications within the home environment.
High conversion rate of sunlight into usable electricity, maximizing energy production even in limited space. Over time, the initial investment in the system pays off through reduced electricity costs and potential incentives or subsidies.
95% high light transmittance: allowing more sunlight to reach the photovoltaic cells for efficient energy conversion.
Over 21% conversion rate: ensuring a high output of electricity from the captured sunlight.
Easy Installation: equipped with aluminum frame to ensure safety and metal bracket for easy installation. Can be fitted independently without solar installers’ help.
Great Portability: our solar panels 1/2 times lighter than traditional glass solar panels, so that they can be taken easily when moving in and out of the apartment.
Long Lifespan: Built with high-quality materials and components, the balcony solar system has an extended lifespan, ensuring reliable performance for 20-30 years.
Great heat dissipation: low internal current and low hot spot temperature.
Great Reliability: minimizes micro-crack impacts and enhances product warranty on materials and workmanship.
The degradation rate of solar panels is usually 0.5%-1% per year.
Generally, most high-quality solar panels retain around 80% to 90%. However, the efficiency of solar panels vary based on many factors, such as exposure to extreme temperatures, humidity, or pollution, and maintenance.
There is no solar panel with 100% efficiency. Commonly, we employ solar panels with a power that is 1.3 times that of the system, or to be more precise, the power of the inverter.
For example, if the system has a power of 900w, we need 900w * 1.3, which is approximately 1170w. Given that a common size of a solar panel is 450w, the required number of solar panels would be 2.6. Thus, in this case, we recommend using 3 pieces to ensure sufficient power supply.
The answer is definitely YES. It is a high-return investment with almost zero risk.
Installing some solar panels on your balcony won’t obstruct your view as they can be placed ingeniously.
As an on-grid system, you can directly use the electricity collected by the solar panels. Even better, you can sell the surplus electricity to the grid. It is not only for self-consumption but also a significant step towards achieving financial freedom through this effortless side business.
Yes, by following the instructions, everybody is able to fit solar panels on the balcony by themselves. Products from GIDITA Solar have these qualifications that even ensure your easy installation:
Equipped with aluminum frame and metal bracket for easy installation
1/2 times lighter than traditional glass solar panels
Most governments require a maximum power of 800w. Power greater than this needs to be approved.
Therefore, the power options of an on-grid solar system ranging from 600W to 800W are the most popular. They typically require 2 solar panels of 450W each. Same as we mentioned in the introduction of the on-grid solar system.

The photovoltaic array, composed of multiple solar panels, absorbs the sun’s radiant energy and converts it into direct current (DC) electrical energy via the photoelectric effect.
The DC power then passes through the solar controller for rectification, stabilization, amplification, and filtering. Finally converted into available direct current (DC) electrical energy.
The available direct current (DC) electrical energy output from the controllerdrives the DC water pump. Through mechanical actions like impeller rotation, the water pump extracts water from the water source (such as deep wells, rivers, lakes, etc.) and transports it to the desired locations, such as farmland for irrigation or to storage tanks for human and animal consumption.
Meanwhile, the batteryis also being charged by the energy from controller. In case of insufficient power from the photovoltaic array, the battery can also supply power to the pump.

DC solar water pump systems operate solely based on the DC power absorbed by solar panels from the sun. Thus, it has certain limitations regarding the amount of sunlight. If there is insufficient sunlight, the system will not work.
AC/DC solar water pump systems can operate based on both DC power and AC power sourced from the grid when the sunlight is inadequate.
Solar water pumps are independent of the traditional power grid and can operate normally in remote areas, mountainous regions, deserts, and other areas where power supply is difficult or there is no access to electricity. Their installation location is flexible and can be arranged and installed based on the water source and water demand.
2. Money-Saving and Environmental Friendliness
As a clean and renewable energy source, solar energy does not produce greenhouse gas emissions such as carbon dioxide when used in solar water pumps, making them environmentally friendly. Compared to traditional fuel or electrically driven water pumps, the long-term operating costs are lower, effectively saving energy resources.
3. Reliability and Durability
Solar water pumps have a relatively simple structure with fewer moving parts, resulting in a lower incidence of failures and relatively low maintenance costs. Using high-quality solar panels and water pump components, they have a long service life and stable performance.
It’s time to move beyond the traditional and embrace the future of water pumping with solar water pumps. They are the key to achieving a more reliable and sustainable water supply in the areas that need it most.
The working components consist of a stator with a double-headed helical cavity and a single-headed helical screw engaged within the stator hole. Powered by the DC from solar panels. As the screw rotates, the liquid is continuously pushed along the axial direction.

by cost: Solar Centrifugal Pump System > Solar Screw Pump System > Solar Pool Pump System > Solar Submersible Pump System > Solar Surface Pump System > Solar Sewage Pump System
Please note that this is a rough comparison. The cost and the head of the pumps are also related to factors such as power and size.
It depends on the amount of power you require. Generally, each solar panel represents 450w.
The power options of a solar water pump system ranging from 750w to 2500w are the most popular. They typically need 3 to 8 pieces of solar panels, specifically:
It depends on the type of pump you choose. The Solar Centrifugal Pump System and the Solar Screw Pump System tend to have a higher cost, whereas the Solar Submersible Pump System and the Solar Surface Pump System typically have a lower cost.
Common solar water pump systems are not equipped with batteries. Because the energy source of the DC model comes from solar panels, and the energy source of the AC model comes from the grid.
However, you can also add a battery to the system for energy storage. In this way, when there is abundant sunlight, the battery can store energy, so that the pump can continue to work when the sunlight is insufficient.
AC/DC solar water pump systems mainly operate based on the AC power sourced from the grid when the sunlight is insufficient.
DC solar water pump systems without a battery scarcely operate on cloudy days. If the cloud is not overly thick, the pump system functions less efficiently compared to sunny days since the amount of sunlight reaching the solar panels is diminished. In such circumstances, using an MPPT (Maximum Power Point Tracking) controller will aid in maximizing the power conversion efficiency. Nevertheless, if the cloud is so thick that it prevents sufficient sunlight from penetrating, the system fails to work.
DC solar water pump systems with a battery mainly operate based on the DC power stored in the battery during sunny days. Most of the system does not include battery, but you can get this combination contacting us.

Yes, it is possible to run an air conditioner (AC) on solar power. Solar air conditioning systems use solar panels to convert sunlight into electricity, which can then be used to power the AC unit.
Reduce electricity costs: Nowadays, with the gradual increase in electricity charges, solar energy, as a free resource, can significantly reduce electricity costs. The electricity expenditure of several hundred dollars per month in the past is highly likely to be halved after the addition of solar air conditioners.
Independent and hybrid power supply: In areas with unstable power supply or remote areas, solar air conditioners can operate independently without being restricted by the power grid. In areas with sufficient power supply, solar energy can be used to supplement the municipal power supply to reduce usage costs or municipal power supply can be used in places with weak sunlight to ensure the continuous usability of the air conditioner.
Easy installation and maintenance: Its system structure is relatively simple, the installation process is more convenient, and the daily maintenance cost is usually lower.
Silent operation: Compared to the compressors of traditional air conditioners, solar air conditioners usually operate more quietly. This is because solar air conditioners are equipped with DC-driven variable-frequency compressors, which can reduce motor energy consumption. Moreover, small-load operation can meet the demand, and the low-frequency start-up of the compressor can make less noise and achieve silent operation.
Long lifespan: Also because it can support low-load operation, high-quality solar air conditioning equipment usually has a service life of 20 to 30 years.
Solar panels collect solar energy and convert it into DC power.
When the DC power passes through the controller, it regulates the direct current (DC) to ensure the stable operation of the air conditioning system.
In the outdoor unit, the compressor compresses the refrigerant, increasing its pressure and temperature; the condenser cools and condenses the high-temperature and high-pressure refrigerant gas into a liquid, releasing heat; the fan helps with heat dissipation and improves the heat exchange efficiency of the condenser; and the expansion valve controls the flow and pressure of the refrigerant, reducing its pressure and temperature.
In the indoor unit, the evaporator evaporates the low-temperature and low-pressure liquid refrigerant; the fan blows the air cooled by the evaporator into the room for air circulation; the air filter filters out dust, pollen, and other impurities in the air, providing clean air.
AC/DC hybrid solar air conditioner
Similar to the DC one, an AC/DC module is added which converts the input alternating current (AC) from the grid to direct current (DC).
Btu stands forBritish Thermal Units. Its is a measurement of the amount of energy an air conditioner uses. Approximately, one Btu is the energy released by the burning of a match.
It depends on the amount of power you require. Generally, each solar panel represents 450w.
The power options of an off-grid solar system ranging from 9000 Btu to 24000 Btu are the most popular. They typically need 8 to 21 pieces of solar panels, specifically:
It depends on the capacity and quantity of the solar panels you possess, as well as the energy consumption of each AC unit.
For instance, if you have 30 solar panels each with a capacity of 450w, the total solar energy supply could be approximately 10.4kw. You can choose one of the following options:
Core components such as the compressor, solar panels, and the power control section including the controllerand AC/DC modules need to be replaced because the working principles of the normal AC and the solar AC are significantly different.
Common components like the evaporator, condenser, fan, connection parts, sensor, casing, and frame may be reused in solar AC. However, these components do not guarantee full adaptability and cost relatively little compared to the core components.
Therefore, we do not recommend converting a normal AC into a solar one. Instead, you can choose a reasonably priced solar AC by contacting us.
Solar air conditioners (AC) do not necessarily require a battery to operate. However, you can incorporate a battery into the solar air conditioning system according to your requirements.
Generally, when purchasing a hybrid solar air conditioner, which is the most popular option for most people, some individuals might opt to buy batteries as an accessory.
If you are considering a DC-only solar air conditioner, the majority of people do not purchase batteries along with it. (we do not recommend this type, and there are few such options available on the market)
Most of people do not purchase a battery for their solar air conditioners (AC). If your solar air conditioners are AC/DC hybrid, they can be powered by DC (direct current) power from the solar panels when there is sufficient sunlight and AC (alternative current) power from the power grid when sunlight is insufficient.
Yes, the solar AC can operate during the night time, relying on the power grid.
The reason is that most solar air conditioners are AC/DC hybrid, meaning they can be powered by DC (direct current) power from the solar panels when there is sufficient sunlight and AC (alternative current) power from the power grid when sunlight is insufficient.
Input: Most of the solar lights operate based on the principle of the hybrid solar system.
When the sunlight is sufficient, the solar panels collect energy from the sunlight and convert it into DC (direct current). The controller converts the DC into usable DC and stores some power in the battery.
When the sunlight is insufficient, you can connect the controller to a USB to charge the battery. There is an AC/DC module that converts the AC (alternating current) from the power grid via USB into usable DC.
Output:
When switched on, the DC flows through the light bulb, illuminating it.
When switched off, the light goes out, but the battery keeps charging until it reaches its upper limit.
Yes. As a hybrid solar system, solar lights can accept both AC (alternating current) energy from the power grid via USB and DC (direct current) energy from the solar panels. When using the latter energy source, there is no need for electricity.
There is a switch on the solar lights or solar lighting system. By pressing the switch, you can turn on the solar lights.
As long as the cables between the solar panels, the controller and the battery are connected, the solar panels operate and the battery continues to be charged until it is fully charged.
Usually, the lifespan of solar lights ranges from 3 -10 years. However, it varies depending on the working conditions, the quality of the products, and the frequency of use of each solar light.
While the Solar Portable Lighting System has an external battery. You can replace the battery by unplugging the cable and replacing it with another one.
In principle, you can. But it is not recommended. Because normal batteries cannot be long-term compatible with the solar panels and will affect the operation of the solar lights.
Yes, solar lights are charged when turned off (the switch). As long as the cables between the solar panels, the controller and the battery are connected, the solar panels operate and the battery continues to be charged until it is fully charged.
The solar lights are IP65 waterproof designed and manufactured with high quality sealing techniques to ensure their resistance to water. This means they can withstand normal rainfall without adversely affecting their performance or functionality.
