How Much Does a Typical Home Solar Installation Cost?
How much does a typical home solar installation cost?
1. The first thing to consider is the home roof structure to install. Is it flat or inclined top? In every 10 square meter area exposed to the sunlight 1 KW solar panels can be installed. And 1 KW solar panels cost about 8000 yuan.
2. Solar panel is the core part of the solar power generation system. The role of solar panels is to convert the sunlight energy into electric form and then output direct current which will be stored in its battery. So the conversion rate and service life are important factors which determine whether the solar panel has utilization values.
3. At present, solar cells on the market are divided into amorphous silicon and crystalline silicon types, in which crystalline silicon can be divided into polycrystalline silicon and monocrystalline silicon. The photoelectric conversion efficiency of the three materials are listed below: the monocrystalline silicon (up to 17%)> polycrystalline silicon (12~15%)> amorphous silicon (about 5%).
Therefore, in general, it is advisable to use monocrystalline silicon or polycrystalline silicon as solar cell materials and among the two kinds the price of monocrystalline silicon material is a little bit more expensive.
