How to build a home photovoltaic power generation system?

? 1, equipped. It is difficult for ordinary users to buy equipment conveniently and cheaply. The principle of grid-connected distributed photovoltaic power generation is not difficult, just solar panels, inverters, microswitches (for protection), plus cables, foundations, brackets and other equipment. According to the information collected on the Internet, Xu Pengfei of Qingdao, Shandong Province spent more than 20,000 yuan, but his inverter was bought at the cost price from his own company, and other equipment was also bought at preferential prices from his peers. A man in Shunyi, Beijing, spent 42,000 yuan on all the equipment. He said that if you don't take detours, you can actually invest 30 thousand. This person works for a foreign-funded photovoltaic enterprise. Tamia Liu in Nanchang spent 60,000 yuan. The installed capacity of these people is below 10 kW, generally 5kw or even 1.5kw (basically, they can make light bulbs). Therefore, the cost is still quite high, and it takes some time and energy for ordinary people (without foundation and hobbies) to buy these devices. At present, there is no manufacturer producing complete sets of household photovoltaic power generation equipment in China.

? 2. permission. Installing these devices on your own building requires the consent of the residential property and neighbors. It is best if it is a single-family house. This step is usually the most time-consuming.

? 3. installation. You can only do it yourself, and the words of relevant practitioners can usually be done in a week. The words of ordinary people need to think hard about the principle.
