Customized Online Solar Calculator


With solar power, both ground-mounted and rooftop, growing at a fast pace, many stakeholders are keen to understand the benefits of investing in solar in a more tangible ways.

One of the best ways to get a hang of your solar power investments is through customized solar calculators.

Most of you would have used some rudimentary solar calculators. But these are generic, while for medium and large investors, they would like to have a more custom-made solar calculators.

This is because, depending on the region and also sometimes depending on the specific category of the solar power plant (industry sector, rooftop or ground-mounted), estimates for solar power plants could vary significantly.

This is where a customized solar calculator comes into play.

Solar Mango, the #1 Solar Guide, has the unique intersection of expertise in developing world-class, and highly effective solar power calculators that can be an effective aid in your investment decisions – be they for rooftop or for ground-mounted solar power plants:

Who is it for?

Owing to our consulting team’s understanding of the needs of the various market segments and end use applications, we can develop calculators and estimators for a range of sectors and segments.

Custom Calculators for Different Solar Power Sectors

  • Residential rooftop solar power plants
  • Industrial and commercial rooftop solar power plants
  • Small-medium ground-mounted solar power plants
  • Large solar farms
  • Offgrid solar products – solar streetlights, lanterns, solar water pumps…

Why do you need a Solar  Calculator?

  • Make the stakeholders understand the benefits of solar power in a more tangible manner
  • Make the stakeholders also get a realistic understanding of the constraints of solar power plants
  • Enable stakeholders choose components in an effective manner

Features of the Customized Solar Calculator

The following are the main, generic features that we can include in the solar calculator. Each of these features can be customized based on your requirements. In addition, we can add more features as well, should you need them:

For all types of solar power plants – rooftop and ground-mounted

  • Solar power generation estimates for the entire project lifetime
  • Cost of solar power – this can be customised based on your region, and also based on the financial / fiscal incentives and regulatory structure in your region
  • Financial estimates
    • Equity IRRs
    • Project IRRs
    • Payback period
    • Yearly cash flows (or savings)
    • DSCR (debt service coverage ratio)
  • CO2 emissions – estimate the amount of CO2 emissions avoided using the solar power plant
  • How selection of individual components affects the performance of the solar power plant
    • Panels
    • Inverters
    • Cables
    • Mounting Structures
  • Parameters to be used for selecting solar panels and how each parameter affects performance
  • Parameters to be used for selecting solar inverters and how each parameter affects performance

In addition to the above, the following specific features can be included for rooftop solar power plants

  • For rooftop solar power plants
  • Power plant capacity estimates – based on load, based on rooftop area
  • % of electricity consumption that can be contributed by a rooftop solar power plant
  • Battery requirements based on backup requirements


  • We can also incorporate a concise dictionary within the calculator that provides effective meanings and explanations for key solar power terms.
  • Brief answers to frequently asked questions on solar power can also be provided as part of the calculator.
