Calculate How Many Solar Panel For 3500 Sq Ft Home

Updated september 17 2020 a typical american home will need 14 36 solar panels to cover their power bill and at least 227 square feet of rooftop space to accommodate the solar panels.

Calculate how many solar panel for 3500 sq ft home.

To get these numbers we used high and low panel production ratios to calculate how many solar panels are needed on average. In the example above you would need 24 solar panels to account for 80 of your average consumption 29 6 kwh daily usage divided by 1 24 kwh per panel. For lead acid 24kwh is equal to. Estimating the number of panels based on home area is an indirect approach since you must assume the kwh consumption.

The average cost to install solar panels is from 10 626 to 26 460 after tax credit for a 6kw to 12kw system to power an entire house. Most solar panels last for 50 years have a 25 year warranty and start generating a return on investment after 8. Homes don t use energy people do. However average values can be calculated from official data.

My 3 000 square foot home uses about 2 000 kilowatt hours kwh of electricity each month. One solar panel produces about 1 24 kwh per day. The average solar panel payback period is 7 to 12 years and solar energy saves 600 to 2 000 per year on electricity costs. I ve been at a customer s 2 500 square foot home that uses 3 500 kwh of energy.

The amount of energy that solar panels can absorb and then produce is measured in kilowatts kw. The typical homeowner will need 28 34 solar panels to cover 100 of their energy usage dependent on location and roof size. The energy used by a home and more specifically a homeowner can vary tremendously note. Some homes have more efficient appliances and habits also influence electricity usage.

The ranges we give between 19 and 30 premium solar panels to generate enough electricity for an average 3 000 square foot house were calculated based on houses located in the cloudy northwest such as seattle washington and the very sunny southwest like mesa arizona. We offer off grid packages complete with solar panels racking. Here are example battery banks for both lead acid and lithium based on an off grid home using 10 kwh per day. Use this battery bank size calculator to buy the right battery bank and get years of system life.
