How is photovoltaic power generation profitable?

Distributed photovoltaic power generation can be profitable through the price difference of electricity charges.

For example, invest in building a 5MW photovoltaic power station on the roof of Beijing's own enterprise. The construction investment is about 35 million yuan, and it can generate 6 million kWh of electricity every year. You sell 50% of the electricity to your own enterprise (for your own use), you use it once in 0.8 yuan, and the rest of the electricity is sold to the State Grid (for extra electricity) at 0.39 yuan per kWh, and the state subsidizes you at 0.42 yuan per kWh in Beijing (for 20 years). So you are equivalent to 3 million kWh, five years 1.52 yuan, five years 1.22 yuan, 3 million kWh, five years1.1,20 years 0.86438+0.

In the first five years, your annual sales income was 7.89 million yuan/year, and in the next 15 years, your annual sales income was 6.09 million yuan/year.

Of course, you should also consider the 0.05% annual attenuation of solar panels, linear depreciation of equipment in 10 years, 3% annual inflation, income tax since 10 years, inverter replacement around 10 years, various insurance investments, money for cleaning glass and halving value-added tax, and many other factors.

To sum up, the IRR of a photovoltaic power station mentioned in the above example is about 16% ~ 18%.

If you rent someone else's roof, a 5MW roof usually costs about 250,000-500,000 extra every year, then your IRR will probably drop to 14%- 15%.

Considering that some people will embarrass their peers with the EPC price I gave, I have reserved some space (peers should applaud here). At the same time, please note that the scale of photovoltaic projects will directly affect the cost, that is to say, a 500k project, a 5MW project and a 20MW project have completely different costs!
