Space Requirement Calculator | Estimate Rooftop Area for Your Solar
Know How Much Area You Need for Installation
Wondering if your rooftop is large enough for a solar panel system?
Use the Dhyuti Solar Space Requirement Calculator to quickly estimate the available rooftop area for solar panel installation based on your roofβs length and width.
This tool is ideal for commercial buildings, industrial units, and gated community rooftops where understanding the actual area available is crucial to begin your solar planning.

How the Rooftop Area Calculator Works
Just measure your rooftop and enter the values below:
- β Step 1: Enter your rooftop length
- β Step 2: Enter your rooftop width
- β Step 3: Select units (ft/meter)
- β Step 4: Get your total available area and how many kW of solar panels you can install

Who Can Use This Solar Area Calculator?
This tool is designed for anyone planning a solar transition on large rooftops, including:
Offices, malls, retail stores
Warehouses, plants, logistics units
Common areas like clubhouses & parking
Schools, hospitals, colleges, and more
How Much Area Is Required for 1 kW Solar Panel?
As a general rule:
1 kW of solar panels = ~80β100 sq.ft. of shade-free rooftop space
If your roof area is:
1,000 sq.ft. β You can install approximately 10β12 kW
2,000 sq.ft. β Up to 20β25 kW, depending on panel type & layout
This calculator gives you the raw areaβyou can then match it to the right solar system size.
