The installation of a power generation system will cost about 2,000 yuan per 100W (when the sun is shining on a sunny day, it can generate about 1 kilowatt-hour of electricity), which is roughly equivalent to the cost of 100W solar panels + 12V100A battery, plus other costs~~~
You can equip the solar system with the number of panels and batteries needed according to your own needs (daily power consumption, plus the number of cloudy or rainy days), and the number of solar panels and batteries needed. ), the number of panels and the number of batteries needed to equip the solar system.
By my rough calculations, solar power on your own will cost you about $2.50 or more per kWh of electricity used, a large portion of which is generated on the batteries. (It's too costly to replace them about 2-3 years at a time)
