How much does solar energy cost?

First of all, you need to check the size of the space available in your chicken farm. Generally, a 10 kW photovoltaic power plant can be installed on 100 square meters.

A 10 kW photovoltaic power plant requires an investment of around 80,000 yuan. (Now that the technology has improved, the installation price will be lower and the cost recovery time will be shorter.)

On average, 50 kilowatt hours of electricity are produced each day. It produces 17,000 kilowatt hours of electricity per year.

If you install photovoltaic power generation, you can receive a national subsidy of 0.42 yuan per kilowatt hour and enjoy its benefits for 20 years. For the electricity you use, the state will give you a subsidy of 0.42 yuan per kilowatt hour. Unused electricity will be directly integrated into the public network. The price per kilowatt hour will be 0.3949 (electricity pricetricity to desulfurized coal) + 0.42 (State price). subsidy)

If you do not use the 17,000 kilowatt hours of electricity you produce, all of it will be sold to the State. Earnings appear to be declining.

A photovoltaic power plant can be used for more than 25 years. Once the cost is recovered in 5 years, the remaining 20 years will be pure income.

Now banks also have PV loan policies, and you can borrow at least 80% of the total amount of the installed power plant for eight years. The monthly interest is more than 3%.

Approximately 30 kW of solar panels are required and 125 polycrystalline solar panels of 240 W can be used

As the region is not safe, the actual production capacity of electricity of this quantity is approximately 100 degrees.

Power generation efficiency

The highest photoelectric conversion efficiency of solar energyin monocrystalline silicon reaches 24%, which is currently the highest photoelectric conversion efficiency among all types of solar cells. However, the production cost of monocrystalline silicon solar cells is so high that they cannot be widely and commonly used in large quantities. Polycrystalline silicon solar cells are cheaper than monocrystalline silicon solar cells in terms of production cost, but the photoelectric conversion efficiency of polycrystalline silicon solar cells is much lower. In addition, the lifespan of polycrystalline silicon solar cells is shorter than that of monocrystalline silicon solar cells. cells. . Therefore, in terms of performance-price ratio, monocrystalline silicon solar cells are slightly better.
