If the maximum usage rate of sunlight is about 8 square meters, which generates one kilowatt hour of electricity per hour, and the average sunshine is 6 hours per day, it would take about 500 square meters during the day. The price of solar cells varies depending on the quality. The construction cost is assumed to be 5,000 yuan per square meter, including the cost of the inverter. This would require 2.5 million cold rooms and the construction cost is around 200,000 (simple). For reference
Currently many 250W cards are used
This card is approximately 1.6 square meters (1640*992*40mm)
Be sure to take into account the slope when laying maintenance channels etc.
Generally calculated as 100 W per square meter
A mu of 666 square meters is equivalent at approximately 66.6 kW
A thousand acres is approximately 66.6 MW. It depends on site conditions.
The pays is now vigorously developing grid-connected photovoltaic power generation.
The national subsidy is 0.42 yuan per kilowatt hour for 20 years. /p>
Some places also have local subsidy policies.
p>
Like in Guangdong: Guangzhou, Foshan and Dongguan all have additional subsidies
The installed current capacity is about 10 to 12 yuan per watt
If it is for domestic use, for example, the electricity bill is 6 cents per kilowatt hour and the payback time is around 8 years
For industrial and commercial electricity, the payback time is around 6 years
The lifespan of energy production photovoltaic is around 25 years
It remains profitable in the long term
But the one-off investment is relatively important
