Choose the Types of Solar Power System
The main types of solar power systems are on grid systems, off grid systems and hybrid solar systems. They can be subdivided into the following five types according to their application areas and sizes: portable solar systems, small DC solar systems, distributed solar systems, and solar plant systems.
On grid systems: The solar provides the main power supply, and when the solar is not sufficient, the utility supplies power to the load as a supplement. If the solar output is greater than the load, the excess power is fed back into the utility system.
Off grid system: The solar provides the main power supply, and when the solar output is greater than the load, the excess power is deposited in batteries to provide power to the load at night or when the sun is not abundant. The off-grid inverter also has a utility input port, which supplements the load when the PV and battery power is insufficient for the load.
Hybrid system: Combines the characteristics of grid-connected and off-grid. solar, battery and utility can all supply power to the load, while the excess power can also be fed back into the utility system.
Portable solar system: consists of portable solar panels and portable power supply. Light weight, small size, easy to install, convenient to carry. Widely used in outdoor, camping, RV and other scenes.
Small DC solar system: the output power of solar panels is directly used for DC loads through charge controllers, often used in solar streetlight, garden lights, monitoring, solar water pumps, PV DC air conditioners, traffic signals and so on.
Distributed solar system: the power generated by photovoltaic panels is applied to AC loads through photovoltaic inverters, which is also the most widely used system, such as household photovoltaic systems, industrial and commercial photovoltaic systems, schools, hospitals, factories, enterprises, parking plants, fisheries, animal husbandry, solar farms, broadcasting and communication stations.

How does solar power work?
A solar power system works by converting sunlight into electricity through solar panels. These panels are made of semiconductor materials, typically silicon, which generate direct current (DC) electricity when exposed to sunlight. The DC electricity is then converted to alternating current (AC) by an inverter, making it compatible with standard electrical grids and appliances. The system can be grid-tied to feed excess power back to the grid or equipped with batteries to store energy for use during the night or on cloudy days.

Solar Power System Kit FAQ
To set up a solar power system, you need solar panels, an inverter, mounting hardware, and, optionally, batteries for storage. You’ll also need to choose a sunny location, obtain necessary permits, and ensure proper electrical connections to either the grid or a standalone system.
A PV system does not need batteries to work. It can generate electricity directly from sunlight and feed it into the grid (on grid system). However, batteries are necessary for storing excess energy if you want to use the power during the night or in off-grid systems.
Whether a solar power system is suitable for all houses depends on the specific conditions and surrounding environment of the house. Generally speaking, most houses can be equipped with solar power systems, but factors such as roof orientation, area, strength, and obstruction need to be considered.
The best solar system depends on your needs. Grid-tied systems are great for cost savings and simplicity. Off-grid systems offer independence for remote areas. Hybrid systems provide reliability with grid connection and battery backup. Choose based on your energy needs, location, and budget.
Cleaning is an important part of maintaining solar power systems, and regular cleaning can remove dust and dirt, improving power generation efficiency. It is generally recommended to clean once a year.
