Roof Area to Panel Capacity Calculator
Find out how many solar panels and total capacity (kW) your roof can hold. Adjust for roof area, panel size, spacing, and efficiency.
For a monthly energy usage of 1,000 kWh, you would need at least 17 solar panels and three solar batteries to go off-grid. Assumes 400-watt solar panels and 13.5 kWh lithium-ion batteries. Can solar panels run an entire house?
You can calculate how many solar panels you need by dividing your yearly electricity usage by your area's production ratio and then dividing that number by the power output of your solar panels. To put it simply: Number of panels = annual electricity usage / production ratio / panel wattage
SolarTech's regional production data helps hit that sweet spot for maximum value and performance. Each solar panel requires approximately 17-20 square feet of roof space, including necessary spacing for installation and maintenance. A typical 20-panel system needs 340-400 square feet of unshaded roof area.
A solar panel's wattage has the biggest impact on how much energy it produces. An average 400-watt monocrystalline solar panel will produce 2 kWh of energy per day. Solar panels with higher efficiency ratings will generally have higher wattages and are best for homes with limited roof space.
