Solar panel kwh calculator.

5 kw x 1900 kwh kw x 78 output x 25 or 1 850 per year. On average a normal household will use around 37 kwh per day. Likewise if you wanted to account for 100 of your daily kwh consumption you would need 30 solar panels 37 kwh daily usage divided by 1 24 kwh per panel. Then find that the los angeles area lies within the 1 900 number on the map so the calculation for a 5 kw system would be.

This solar calculator has solar production data from all weather stations around the country and it is also able to show you the cost and savings you will get from going solar.
