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.
GoGreenSolar offers high-performance panels that deliver power output between 335 to 405 watts. Whether you want to offset your energy bill partially or completely, we have solar kits to match your specific energy needs. Your budget often determines the size of the solar system you can afford. Solar panels are just one part of the equation.
For a typical 7 kW system, expect to need 18-20 panels in this category. Standard efficiency panels are ideal if you have a large, unobstructed south-facing roof and want to prioritize lower installation costs over maximum power density. They’ll deliver strong long-term performance and reliable energy production.
Yes, in many cases a 10 kW solar system is more than enough to power a house. 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.
