The amount of electricity a solar panel can produce in a day is related to the electricity production efficiency, surface area, sunshine duration and sunshine intensity of the solar panel. solar panel.
Solar panels are also called solar cell modules. Most simple solar cells cannot be used directly as power sources. Multiple individual cells must be connected in series, parallel and tightly sealed into components, i.e. solar panels.
The solar cells that make up a solar panel can be made from different photovoltaic materials. Currently, crystalline silicon materials, including polycrystalline silicon and monocrystalline silicon, are the most important photovoltaic materials. Among them, the photoelectric conversion efficiency of single-crystal silicon solar panelsstallin is about 15%, the highest reaching 24%, and the conversion efficiency is very high; the manufacturing process of polycrystalline silicon solar panels is similar to that of monocrystalline silicon solar panels, and the photoelectric conversion efficiency is only about 12%, the highest is about 15%, but the The cost is very low and the overall cost-performance ratio is currently higher than that of monocrystalline silicon solar panels. There are also amorphous silicon solar panels, multi-compound solar panels, etc. The highest efficiency among different solar panels is around 40%.
The energy production of solar panels is related to the efficiency of electricity production, the size of the area, the intensity of sunlight (weather) and the duration lighting (season). In practical applications, it is also affected by the efficiency ofcharging and discharging of energy storage equipment (battery) and by the efficiency of electrical energy conversion (in grid power specifications)...
In projects engineering (such as the construction of solar-friendly buildings), it is generally estimated based on 6 hours of sunshine per day and an energy production per panel of 100 W per square meter. That is: 0.6 kilowatt/day but in fact, the instantaneous production of electricity in summer, when the sunshine is strongest, can reach 1 kilowatt/hour, which is 10 times different from the estimated average value.
