How to purchase solar photovoltaic power generation panels is as follows:
Conversion efficiency: The conversion rate of a photovoltaic solar panel refers to its efficiency in converting sunlight into electrical energy. The higher the conversion rate, the better the power generation effect. Generally speaking, photovoltaic solar panels with conversion rates above 17% to 20% are considered efficient.
Material quality: The material quality of photovoltaic solar panels directly affects their lifespan and performance. Common solar panel materials currently on the market include monocrystalline silicon, polycrystalline silicon and amorphous silicon. Monocrystalline silicon photovoltaic solar panels have high conversion efficiency and long service life, making them an ideal choice. Although the conversion efficiency of polycrystalline silicon photovoltaic solar panels is slightly lower, the cost is relatively low.
Durability: Solar photovoltaic panels are usually installed outdoors and need to withstand various climatic conditions, so it is necessary to choose products with durability.
