The solar panel battery cost involves solar photovoltaic panels, solar energy storage cells and installation costs.The price of solar panels is not necessarily fixed, which needs to be determined according to the market situation of silicon raw materials. In addition, solar panels are also divided into monocrystalline silicon and polycrystalline silicon. Monocrystalline silicon solar panels have high crystal purity and relatively high price, but their power generation performance is better than polycrystalline silicon solar panels.

The solar cells of the solar panel are divided into crystalline silicon (single crystal, polycrystalline, Sunpower) solar panels and amorphous silicon (CIGS, etc.). The order of conversion efficiency from high to low is: Sunpower (conversion efficiency is about 22%)>single crystal solar cells (conversion efficiency is about 20%)>polycrystalline solar cells (conversion efficiency is about 18%)>amorphous solar cells (conversion efficiency is about 14%), The prices from high to low are: amorphous silicon solar cells>Sunpower solar cells>single crystal solar cells>polycrystalline solar cells

Secondly, the price of 48V 100AH lithium battery is also affected by many factors, such as market conditions. When supply exceeds demand, the price of lithium powerwall battery will be relatively low; When the supply exceeds the demand, the cost of lithium battery will be relatively high. Secondly, the different raw materials of battery core will also affect the price. Product A must be more expensive than the battery core of Product B, thus affecting the solar storage battery cost.
Secondly, the installation costs vary from country to country. For example, Germany and Malaysia have higher installation costs than Malaysia.
