To determine how many solar panels you need, you'll consider factors like your energy consumption, location, panel efficiency, and available roof space.
Energy Consumption: Calculate your average monthly energy usage in kilowatt-hours (kWh). This information helps estimate the system size needed to cover your needs.
Location: The amount of sunlight your location receives affects panel efficiency. Sunnier regions require fewer panels to generate the same energy.
Panel Efficiency: Different panels have varying efficiencies. Higher efficiency panels produce more energy in less space.
Roof Space: Assess available roof area for panel installation. More space allows for more panels.
System Size: Divide your monthly energy usage by the average output of a single panel to estimate the number of panels required.
Consult a solar professional for accurate calculations tailored to your situation.
