Question: how many solar panels do i need to power my house calculator?
Answer: To figure out how many solar panels you need, divide your home's hourly wattage requirement (see question No. 3) by the solar panels' wattage to calculate the total number of panels you need. So that average U.S. home in Dallas, Texas, would need about 25 conventional (250W) solar panels or 17 SunPower (370W) panels.
