Solar calculator to calculate your solar system size

During the current situation, the electricity prices in Pakistan rise day by day. According to the world bank report Pakistan has the 40 GW solar potential. Now people want to shift towards renewable energy mainly solar energy. Most People are non-technical and face difficulty in selecting the size of the solar system.

To facilitate the users, I have developed a solar calculator with the help of Mr. Sarmad (BS CS student) for the estimation of the size of the solar system. By using this calculator a citizen has an idea about the size of the solar system as well as the prices of panels and backup batteries.
