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.
On average, it takes roughly 17 (400-watt) solar panels to power a home. However, the number of panels needed can range from 13 to 19, depending on solar exposure and energy demand. Larger homes may require more solar panels. Nationwide, over 179 (GW) of solar capacity is installed, capable of powering roughly 33 million homes.
Divide the average daily wattage usage by the average sunlight hours to measure solar panel wattage. Panel output efficiency, energy usage, sunshine exposure, system capacity, panel types, and materials all impact the calculation.
As we calculated earlier, the California household needs a 7.2 kW system to cover its electricity needs. A comparable household in Massachusetts needs a 9.9 kW system. So, in less sunny areas like Massachusetts, you might consider choosing highly efficient solar panels to maximize your energy output per square foot.
Our photovoltaic systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
