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. However keep in mind that there are many factors at play here so this is really only a rough estimate. Or in massachusetts where electricity costs 20 kwh and a kw of solar panels makes about 1 500 kwh per year the panels save you 1 170 per year. 5 kw x 1900 kwh kw x 78 output x 25 or 1 850 per year.

So if you have solar panels that each produce 1 kwh of power per day you would need a full 37 solar panels to fully power your home. One solar panel produces about 1 24 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. To figure out how many kilowatt hours kwh your solar panel system puts out per year you need to multiply the size of your system in kw dc times the 8 derate factor times the number of hours of sun.

On average a normal household will use around 37 kwh per day. The tool works by taking your average monthly energy usage in kilowatt hours kwh. Solar system output calculator calculate the average daily kwh hour output in your area based on a well installed solar system in a suitable position e g no overshadowing. 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.
