What is a Solar Rooftop Calculator?

Solar Rooftop Calculator is an online tool that estimates the solar energy production of your rooftop solar panel system. By considering your location, roof area, and energy needs, the calculator provides insights into how much electricity you can generate and potential savings.

How to Use the Solar Rooftop Calculator

  • Step 1: Enter the total roof area available for solar panels in square meters.
  • Step 2: Choose the solar panel efficiency percentage from the provided options.
  • Step 3: Enter the average sunlight hours your location receives each day.
  • Step 4: Click the "Calculate Solar Energy" button to view the estimated daily energy generation.

How the Solar Rooftop Calculator Works

This calculator estimates solar energy production using the following formula:

Energy (kWh) = Roof Area (m²) × Solar Panel Efficiency (%) × Sunlight Hours (h)

It calculates the potential daily energy generation based on the roof area available for solar panels, the efficiency of the panels, and the average number of sunlight hours in your region.

Example of Using the Solar Rooftop Calculator

For example, if your roof area is 50 m², you choose solar panel efficiency of 20%, and your location receives 5 sunlight hours daily, the calculation would be:

  • Energy = 50 m² × 0.20 × 5 h = 50 kWh

This means you can potentially generate 50 kWh of energy per day from your rooftop solar panels.

Solar Rooftop Calculator Formula

The formula for calculating the estimated energy generation is:

  • Estimated Energy Generation (kWh) = Roof Area (m²) × Solar Panel Efficiency (%) × Sunlight Hours (h)

Frequently Asked Questions (FAQs)

The Solar Rooftop Calculator helps users estimate the potential energy generation from solar panels installed on their rooftops based on available area, panel efficiency, and sunlight exposure.

You can measure your roof area by calculating the length and width of the roof and multiplying them together. Alternatively, you can use online mapping tools to estimate the area.

Solar panel efficiency refers to the percentage of sunlight that a solar panel can convert into usable electricity. Higher efficiency panels generate more electricity from the same area.

Sunlight hours refer to the average number of hours your location receives direct sunlight each day. You can find this information through local weather data or solar radiation maps.

The calculator provides an estimate based on inputs. Actual energy generation can vary based on factors like shading, panel orientation, and local climate conditions.

Yes, this calculator is primarily for rooftop solar installations but can also provide estimates for ground-mounted systems if you adjust the roof area input accordingly.
