Daily electricity consumption is 3,700 Wh, or 3.7 kilowatt hours of electricity per day. Solar energy production is not calculated based on lighting duration. The lighting duration must be converted to standard lighting duration (illuminance of 1000 W/m2). 25 degrees Celsius), which is calculated on average in Guangxi. It takes about 3 hours at most, so it is necessary to install at least a 1.2 kW photovoltaic power generation system to meet the needs, and the investment is about 30,000-40,000 yuan. .
The power output per day is 2100W. This is calculated based on the 70% photoelectric conversion rate of each solar panel, i.e. the average of 6 solar cells per day. . The quantity of electricity produced per hour of sunshine.
Distributed photovoltaic power generation projects can choose when filing:
"Auto-ut"spontaneous use, surplus power grid" or "Complete grid", spontaneous self-use, surplus power grid refers to photovoltaic power generation. Part of the energy generated by the system is used by the users themselves, and the Excess electricity is connected to the grid and sold to the power grid company; full grid connection means that all the energy produced is connected to the grid and sold to the power grid company, and the basis of. Settlement is based on the bidirectional meter installed on the user's side when connected to the network
