People often consult: "how much is the price of photovoltaic power generation installation per square meter" or "how much photovoltaic can be installed per square meter"? How much does it cost......?Photovoltaic problem in the "one square meter" such a question, how should answer it: one is that photovoltaic is not installed according to the area of square meters, the other is to answer according to the quantity of electricity, and the area does not have much relationship. But this problem is the owners of urgent things to know, we consider for the owners from a professional point of view for everyone to try to explain the "photovoltaic square meter" problem.
One, 1 square meter roof can be installed how much photovoltaic?
The area of the distributed photovoltaic power station is converted into something like this: about 100 watts of components per square meter can be installed on the ground and on the concrete roof; 100 to 120 watts of components per square meter can be installed for sloping colored steel roofs and sloped tile roofs.Although we give a data, we still need to carry out preliminary investigation before installation. If there is shelter, obstacle, etc., we also need to recalculate. This is only a reference data.
How much does a power station of 1 square meter cost?
This question is really not professional, because the unit of measurement of photovoltaic power stations is watts (W) or kilowatts (KW), the current market installation price should be about 8-10 yuan/watt, a square meter can be installed about 100 watts, then we can not professional answer you: the installation of photovoltaic per square meter about 800-1000 yuan of capital. This is also a reference. If the installation is difficult and the distance from the grid is long, the owner will put forward some reinforcement ideas, which will increase the cost of the power station project.
3. How many kilowatt-hours of electricity can a square meter produce every day?
Under normal circumstances, each kilowatt in North China generates about 4 to 5 kilowatts of electricity per day, or about 0.4 to 0.5 kilowatts per square meter per day, or about 140 to 180 kilowatts per year.
Four, 1 square meter of photovoltaic a year how much money?
The amount of income is closely related to national policies. In 2018, the subsidy policy was adjusted, mainly: subsidy per kilowatt hour was lowered from 0.42 yuan to 0.37 yuan; The on-grid price of standard desulphurized coal in the three regions has been reduced from 0.85 yuan/KWH to 0.75 yuan/KWH. Based on the annual power generation capacity of 1 square meter, it can be easily calculated that the annual income
of 1 square meter photovoltaic power station is about 100 yuan --140 yuan.
