6. How is the return on investment?
(1) Calculation Method
Assuming an initial investment of 50,000 RMB for a station in a certain area of Jiangsu Province, with 70% self-consumption and 30% surplus electricity fed into the grid, and annual effective sunlight of 1248 hours, calculated at a desulfurized coal-fired electricity price of 0.391 RMB/KWh and local peak electricity price of 0.5583 RMB/KWh, taking into account the attenuation of the station.
(2) Overall Profit
According to professional estimates by GCL SUN, after 25 years of the full lifecycle, the total revenue (including self-use electricity fees and grid feed-in tariffs) of the photovoltaic station can reach 300,000 RMB. The user’s one-time investment can be recouped within 4-7 years.
