Solar energy calculations

How is solar energy calculated?

You can calculate how many solar panels you need by multiplying your household’s hourly energy requirement by the peak sunlight hours for your area and dividing that by a panel’s wattage. Use a low-wattage (150W) and high-wattage (370W) example to establish a range (ex: 17-42 panels to generate 11,000 kWh/year).

How is solar plant capacity calculated?

Now, the capacity of solar panels required (in kiloWatts kWp) for your use can be calculated by dividing your consumption or part of consumption that you want to meet from solar by 120.

How do I calculate kWh?

A kilowatt-hour, expressed as kWh or kW·h, is a measure of energy that is equivalent to 1,000 watts of power for a 1-hour time period. Thus, to convert watts to kilowatt-hours, multiply the power in watts by the number of hours, then divide by 1,000. For example: let’s find the kWh of 1,500 watts for 2.5 hours.
