Approximately 5 to 7 years.
The recovery cycle of a household photovoltaic power plant is related to the electricity production of the photovoltaic plant, and the electricity production is directly related to the income of the photovoltaic system.
The cost of installing a photovoltaic plant at home depends on the installation capacity and the budget. A photovoltaic plant of around 10 to 13 kW can be installed on the roof of a 100 square meter bungalow. Assuming that 10 kW is installed, the market price will be around 75,000 yuan. This includes photovoltaic modules, inverters, distribution boxes, brackets, photovoltaic cables, MC4 connectors, etc. in photovoltaic system, early-stage site survey, mid-stage design and construction, and late-stage grid connection after-sales.
Detailed information:
Generally speaking, when producing photovoltaic modules, instructions will be attached. It is strictly prohibited to work on the glass surface of the solar panel to avoid glass breakage and injury.
At the same time, please note that when constructing during the day or in the sun, professional Blue Sky installers from Jiaotong University recommend using black opaque materials to cover the solar panels to to avoid any damage to people, personal accidents or fires.
Baidu Encyclopedia - Photovoltaic Power Generation
Six elements are required for grid connection:
1. Solar panels
.2. Photovoltaic combiner box
3. Photovoltaic inverter
4. Solar support
5. electric meter installed by the electricity network company
If it is intended for domestic usetick, simply add the bracket and cable. Don't forget to buy the MC4 photovoltaic cable connector.
