The quote per watt varies, there is no uniform price and the price is based on ease of installation. If it is installed on the ground, the installed capacity is more than tens of megawatts, and the installation fee is about 0.30 yuan per watt. If the installed capacity is several megawatts. For tiles, installation costs. is about 0.50 yuan per watt.
If installed on the roof and used at high altitude, the installed capacity is a few hundred kilowatts, and the installation fee is about 0.80 yuan per watt if it is particularly difficult to do so. installation, the installation fee is approximately 1.00 yuan per watt.
