If we install a 2MW solar rooftop system using high - efficiency monocrystalline panels with an optimal orientation and tilt, we might be able to achieve the 2MW capacity in around 10,000 -
Determining the number of square meters of solar panels required for a roof depends on several factors, including energy consumption, solar panel efficiency, and geographical location.

The Solar Power Roof Area Calculator is a valuable tool designed to help users estimate the required roof area for installing solar panels. Its primary use is to determine how much space is necessary on a roof to accommodate a specific amount of solar power generation.
To calculate how many panels can fit on your roof, divide your open roof space by 20 square feet (or however large your particular solar panels are). For example, if you have 500 square feet of open, available roof space, that's enough space for about 25 solar panels.
Let’s take a big 2000 sq ft roof as an example. Such a big roof has 1500 sq ft of viable solar panel area. If each of these viable square feet generates 17.25 watts of electricity, the combined 1500 sq ft will be able to generate more than 25kW per peak sun hour (25.875kW, to be exact).
Our solar panel calculator helps you determine how many solar panels can be installed on your roof and how much electricity they can generate. It calculates the maximum number of panels that fit on the available roof surface, taking into account important factors such as orientation, inclination, and panel type.
Check your panel specs or use an average value. Solar Panel Area (m² per panel)Standard panels are about 1.6–2.0 m². Enter your panel's area or use an average. Panel Placement Loss Factor (%)Accounts for gaps, shading, tilt, and access. 5–15% is typical. Available Roof Area (m²)How much usable roof space do you have for panels?
This is a standard 10kW solar system, consisting of 25 400-watt solar panels. As we will see in the summarized chart below, the minimal roof size for a 10kW system is only 800 sq fr roof area (600 sq ft viable for solar panels due to 75% code consideration)
