How much does it cost for medium-sized hotels to generate electricity with photovoltaic panels? At present, it consumes 2000 kWh of electricity every day. How much can it be recovered? Thank you very much. The conversion rate of solar energy is only 20%, and the longer it takes, the more it will be consumed. You can provide 2000 kWh of electricity every day, but the problem is not the cost, but the power generation of 2000 kWh per day. Do you know how big this area is? Under normal circumstances, it is every square meter 150 W every day, and electricity consumption needs at least 8 square meters at a time, which means that you need at least 16000 square meters of roof without shading. Over time, you have to pay the electricity bill on cloudy and rainy days. If the cost is around 600 yuan and can be controlled in such a large area, then the commercial electricity consumption per kilowatt hour is calculated according to 1 yuan; Very uneconomical
