The number of private solar power plants is increasing every year. Unlike industrial plants, where maximum available power is a priority, owners of home solar modules have to carefully calculate the cost for each kilowatt.
And if the potential needs for electricity for a house or summer cottage have already been calculated, it remains to determine how much power one 325 watt solar panel provides, depending on the climatic characteristics of the region, seasonality, the magnitude of solar insolation, the place of installation, the presence of rotary trackers, types of panels, efficiency, etc.
The amount of solar insolation in different regions of even one country differs significantly. On average, it can be assumed that every 1 kW of power of modern high-quality panels will provide approximately the same annual electricity generation by region under ideal conditions:
- Northwestern, northeastern – about 1070 kWh
- Northern, central, partly southern – up to 1350 kWh
- Southwest – 1350-1600 kWh
How much energy a 325-watt solar panel provides is most influenced by weather conditions and especially the time of a day. So far, there are solar power systems on the market that are not capable of generating energy at night. The generation of such solar systems at night equals zero. In the early morning, late evening, or on a cloudy day, energy production does not stop; it will go on continuously, just not as much. In winter, energy production is slightly reduced because the angle of incidence of the rays is too small when the sun is low. An important detail is the presence of batteries in the solar station, without which, the supply of energy at night is impossible.
The ideal conditions for the location of solar panels are:
- Perpendicular placement of the battery plane to the direction of the rays
- South orientation
The variety of models and manufacturers of 325-watt solar panels presented in the catalog will help you to choose the exact option, based on your needs and characteristics of the house. Innovative energy-efficient panels by Panasonic are coated with the finest layers of amorphous silicon to minimize panel defect areas. The top of solar cells is protected by the light-absorbing glass with a special texture, thus maintaining high performance in low light conditions. The strength of structures is provided by an aluminum frame with a special drainage system, which prevents water retention on the solar panel surface. In hot conditions, it produces 10% more electricity than standard modules. By choosing the HIT model, you will get 19.7% more electricity from each square meter, as well as significantly save on fixings and installation work.
Trina Solar is a manufacturer of solar panels, which has been one of the top companies in the world for the sale of PV modules over the past years. This company is engaged not only in the manufacture of solar cells; it also invests resources in research and development activities and constantly improves the manufacturing process. These solar panels are always cutting-edge technology. They are powerful, reliable, and durable; perfect for on-grid and hybrid solar stations.
From the above examples, it follows that even light, compact, and mobile panel is capable of charging various mobile devices during the day and lighting a pair of lamps at night. A module of two or three 325-watt solar batteries will be enough for a comfortable stay in a country house on weekends. A mini solar power station of 3-4 kW will perfectly cope with the round-the-clock supply of electricity to your home.
Do you want to buy solar panels for your yacht, production, or you want to build a solar power plant at home? In this article, we tried to explain how much power a solar power plant can generate and what the difference between the most popular types of solar panels is, and what their advantages are.
