Calculating area requirements for 1 kW rooftop solar PV system

 Utilize the clean form of energy by installing solar PV systems on the rooftop. But for this, some technical aspects have to be considered. One such important factor is the area that is needed for the 1kW Solar Rooftop Installation.

Aspects to remember before installing the rooftop solar PV system:

·         The shadow test is very important before the installation of the solar system. In this test, optimum solar energy has collected. For this, the panels have to be installed in the south direction. Choose an area where there is no shadow of trees and buildings.

·         You also have to take into account how much load the roof can bear. The weight of solar panels is an important aspect. The weight of the solar panel depends on its size and structure.

·         The output per panel, efficiency of the panel, and solar radiation are also some important factors. Using these aspects capacity utility factor or CUF is determined. CUF of around 19% is considered in our country. The number of units that are generated annually is calculated using the formula Units Generated Annually (in Kwh) = System Size in Kw * CUF * 365 * 24

·         The size of the solar set-up and the cost of setting up are also taken into consideration. Along with installation cost, the Rooftop Solar System Maintenance cost also has to be considered.

Here is how to calculate the area required for a 1kW rooftop solar PV system:

·         The rooftop space is crucial for setting up a solar PV system. For calculating the area needed for a 1kW rooftop solar system take into account the area of each panel. Now divide the available area of the roof with the area of each panel. This you have to multiply by the panels' rated output.

·         Generally, you can consider 70% of the roof area for estimation purposes. But in the case of a large set up 90% area of the roof has to be considered.

·         Since 1kW energy is absorbed by a 1sq m area of the earth. But the efficiency of the solar panels used in the Solar Rooftop Installation has to be taken into account. This efficiency is around 15 to 18 %. This means for a 1sq m area the power that is generated is around 150W to 180 W. And that for 1kW power, a 10 sq m area of the rooftop is needed.

Keep in mind that this is just an approximate value. It is better to hire experts who have the technical expertise to determine the exact value. These experts take into consideration the size of the panel, available roof area, and other factors. Based on these factors they make the exact calculations.
