How many solar panels do I need to power my house?

One of the first questions homeowners ask when going solar is "How many solar panels do I need to power my home?" The goal for any solar project should be 100% electricity offset and maximum savings — not necessarily to cram as many panels on a roof as possible. So, the number of panels you need to power a house varies based on three main factors:

4 FAQs about [Solar pv estimator]

How accurate is a solar estimate based on a monthly electric bill?

Although not very accurate, you can use the amount of your monthly electric bill for a ballpark estimate of how much solar is needed. Select the closest monthly electric bill amount below to see an estimate.

Can I still use solar resource data in PVWatts ®?

You can still use solar resource data available in the older version of PVWatts ® by choosing a legacy data option, but we recommend using the new data because of its higher quality, better spatial resolution so you can use data for the exact location of your project, and because it covers a larger part of the world.

What kilowatt-peak (kWp) should a pvgis value be?

The peak power should be entered in kilowatt-peak (kWp). PVGIS provides a default value of 14% for overall losses in the solar electricity production system. If you have a good idea that your value will be different (perhaps due to a highly efficient inverter), you can slightly reduce this value.

How does solar radiation affect photovoltaic production?

The solar radiation and photovoltaic production will change if there are local hills or mountains that block sunlight during certain periods of the day. PVGIS can calculate the effect of this by using data on ground elevation with a resolution of 3 arc-seconds (approximately 90 meters).
