The payback period for 3000W is approximately 5 years. The general lifespan of solar panels is 25 to 30 years. The national subsidy in Shijiazhuang region is 1.2 yuan/kWh. The greater the installed power, the faster the payback period, approximately 4 to 5 years for 5,000 W.
The amount of investment in photovoltaic energy production projects is generally determined by the following factors:
First, it is determined by the size of your installation site. A great site. have a large installed capacity and a large profit, and vice versa< /p>
It is determined based on the size of the installed capacity, that is, the larger the installed capacity, the greater the The investment is important, and of course the profits will be the greatest.
In fact, the investment amount is put aside first, and whether it can ultimately be connectedto the network is the key! Otherwise, all investment will be in vain.
I hope you will adopt it!
