If you''ve ever thought about putting solar panels on your roof, you know that the process doesn''t exactly qualify as an impulse purchase.
Multiplying the number of panels by the 400-watt power output of each panel gets us a system size of about 16.8 kW. Finally, 16.8 kW translates to roughly 21,840 kWh of production per year when you factor in the production ratio (16,800 W x 1.3).
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: In this article, we’ll show you how to manually calculate how many panels you’ll need to power your home.
In some cases, way more than you probably need. According to our calculations, the average-sized roof can produce about 21,840 kilowatt-hours (kWh) of solar electricity annually—about double the average U.S. home's usage of 10,791 kWh.
Solar panel power ratings range from 250W to 450W. Based on solar.com sales data, 400W is the most popular power rating and provides a great balance of output and Price Per Watt (PPW). If you have limited roof space, you may consider a higher power rating to use fewer panels. If you want to spend less per panel, you may consider a lower wattage.
The average US household uses around 30 kWh of electricity per day, which can be offset by a 5 to 8.5 kW solar system (depending on sun exposure). See how much solar panels cost in your area. Zero Upfront Cost. Best Price Guaranteed.
For example, a 10 kW system that produces 13 kWh of electricity annually has a production ratio of 1.3 (13/10 = 1.3). Ideally, your solar panels will be installed on a south-facing roof at an angle of about 30°. These are the optimal conditions for solar panel production. The closer you get to this, the more electricity your panels produce.
