How many batteries are needed for 100 kW photovoltaic energy storage?

How many batteries are needed for 100kw photovoltaic energy storage?

Firstly, the sunshine duration and charging efficiency of where the photovoltaic panels are installed must be determined.

If the charging efficiency is 80% and the sunshine duration of a day is 10am to 4pm, then the charging capacity is 100KW*6h*80%=600KWh* 80%=480 kWh.

If you choose a 48V energy storage lithium battery, a total of 100 stacked 48V 100Ah (4.8 kWh) rack modules with this capacity are required.

In terms of cost, the cost of photovoltaic panels is calculated based on 2 yuan/W, 100KW*2 yuan/W=200,000. The cost of a battery storage system of Energy stacked lithium iron phosphate is about 5,500 yuan, and the cost of 100 units is 550,000 yuan. The total cost of photovoltaic panels + energy storage batteries (built-in BMS) is700,000 RMB, excluding inverter installation costs and labor.

The total budget therefore requires 1 million (plus inverter installation costs and labor). Such energy storage systems are typically used in small industrial and commercial applications and are not affordable for households. Yes, at least for adults. Villa.
