Along with furnishing results based on a set of pre-set robust algorithms, the advanced MYSUN Solar Calculator also gives one the convenience to see more precise estimations through it’s feature of customize input fields.

Using this online solar calculator is extremely simple. All you need to do is input three basic details - your location, your monthly electricity bill and your electricity consumer category. And the solar calculator will provide you with an unbiased snapshot of your solar potential. After the snapshot is displayed, you can further indicate your electricity consumption pattern, your sanctioned load, your monthly electricity consumption or the diesel backup power that you must be using, to see the most close to true picture of what your savings would be like when you do go with a solar rooftop PV plant. The snapshot or as we at MYSUN like to call it, your personalised solar scorecard, is generated from the calculator in the form of a neat PDF report, that can also be shared with your friends and family.

You can also change the direction of the panels with regards to the Sun and see the impact of your solar panel direction on the energy generation.This is how, the MYSUN Solar Calculator gives a very accurate picture of your solarization potential. Moreover, it will also tell you what kind of appliances you can run with solar for how many hours in a day. You can also adjust your day time energy consumption to fine tune the most suitable solar PV system design for you.
