Technical FAQs 4

How do I choose a solar panel wattage?

Choose from common solar panel wattages: 300W, 350W, 400W, or 450W. The best solar panel will balance cost, efficiency, and roof compatibility. 5. Divide System Size by Panel Wattage To find out the number of solar panels: Number of Panels = System Size (Watts) / Panel Wattage Example: 3950W / 400W = ~10 panels

How many 400 watt solar panels on a 1000 sq ft roof?

A typical 400-watt solar panel is 79.1 inches long and 39.1 inches wide, taking up 21.53 sq ft of area. If you have a 1000 sq ft roof and you can use 75% of that roof area for solar panels, you can theoretically put 34 400-watt solar panels on a 1000 sq ft roof.

How to calculate required solar panel capacity?

To calculate the required solar panel capacity, use the following formula: Required PV panel wattage (Watts) = Average Daily Energy Consumption (kWh) / Average Daily Sunlight Exposure (hours). For example, if your average daily energy consumption is 30 kWh and average daily sunlight exposure is 5 hours, then the required solar panel output would be 6 kW.

How many solar panels can be installed on a roof?

Divide System Size by Panel Wattage To find out the number of solar panels: Number of Panels = System Size (Watts) / Panel Wattage Example: 3950W / 400W = ~10 panels Available roof space limits how many panels can be installed. Measure usable space, excluding shaded or obstructed areas.
