The wattage of a home solar panel should be considered based on factors such as household electricity consumption, lighting conditions at the installation site, and budget. In theory, the power of 1 square meter of solar panel is about 140~150W, but the actual power generation will also be affected by the daily light situation, such as rain, cloudy days, morning, evening, and other factors.
When choosing a home solar panel, in addition to power, you need to pay attention not only to the power, but also to its voltage. Generally speaking, the voltage of solar panels used in homes is usually 12~24 volts. If a household consumes a lot of electricity, then a higher voltage solar panel is needed to provide adequate electricity supply. In addition, there should be a match between the wattage and voltage of the solar panels to avoid the wrong choice of solar panels.
In addition, the type of home solar panel is also a factor to consider. There are many types of solar panels in the market, such as wafer solar panels, amorphous silicon solar panels, flexible solar panels, copper selenide, indium gallium, and polycrystalline silicon solar panels. Each type has its own characteristics and applicable scenarios, so it is necessary to choose the most suitable type according to the real situation in the family.
In general, the wattage of a home solar panel should be determined based on actual demand to ensure the maximum economic and environmental benefit while meeting the electricity needs of the home. When selecting and installing home solar panels, it is recommended to consult a professional solar installation company or agency for more accurate advice and guidance. …
