Calculation formula for energy storage cost per watt in 2023
240KW/400KW industrial rooftop - commercial rooftop - home rooftop, solar power generation system.
To calculate how much a device or appliance costs to run, simply multiply the amount of energy used (kWh) by the unit cost of one kWh. For example. If an oven uses 2000 watts of electricity, or 2 kW, and you use the oven for 2 hours, then you will have used 4kWh. If the unit cost of 1 kWh is 35p for example, multiply 35p by 4.
