Do you know about European power grid, electricity price and photovoltaic standards?
This article by Guruiwatt has been answered. The voltage of European power grid is the same as that of Chinese mainland, with a low voltage of 230 V for single phase/400V for three phase and a frequency of 50Hz. The AC output voltage of medium-voltage grid-connected inverters in Europe is generally 480V V V. Unlike Chinese mainland, residential electricity consumption in Europe is much more expensive than industrial electricity consumption. The electricity consumption of Danish residents is about 2.32 yuan/kwh, that of German residents is about 2.25 yuan/kwh, that of Spanish, Portuguese and Italian residents is about 1.8 yuan/kwh, and that of Britain, Sweden, Switzerland, France and Norway is 1.5-65. If the proportion of distributed solar energy is high, the cost can be recovered in five years. The industrial electricity price is generally 60-80% of the residential electricity price.
