A photovoltaic (PV) system is made up of one or more solar panels, inverters, and other electrical and mechanical components that use the sun's energy to generate power. PV systems come in a wide range of sizes, from small rooftop or portable systems to large utility-scale power plants. Solar energy system converts solar energy into electrical energy which house appliances can use or sold to the public grid.
1.On Grid PV system: Directly connected to the public grid, the generated electricity is fed into the grid and used for household appliances.
2.Off-grid PV system: Operates independently of the public grid, usually equipped with energy storage equipment ( lithium batteries or lead-acid batteries) to achieve energy independence.
3.Hybrid PV system: Works both on grid mode and off grid mode, it can be connected to the public grid and energy storage system at the same time, using solar power generation to supply electricity during the day, and storing the surplus electricity in batteries or feeding it into the public grid; using energy storage electricity at night or during power outages.
Solar system lifetime is usually around 25-30 years, but the actual life span varies depending on the level of maintenance and environmental conditions.
The main products are as follows:
1.Solar panel: generally 25-30 years;
2.Inverter: 2 years for off grid inverter, 5-10 years for hybrid inverter & on grid inverter;
3.Energy storage battery: 5-15 years, depending on the specific type and usage;
4.Bracket and mounting structure life span: 25 years (usually matched with the solar panel).
5.Cables and connectors: 10-20 years, high-quality materials can extend the life span.
