It just
makes sense . . .

The Earth receives enough sunlight in one hour to power the world for over a year

So little of the Earth’s energy requirements is derived from solar power. It’s there for us every day, it’s free and it’s far better for our environment than traditional fossil fuel resources. Whilst researching the merits of solar power panels for our rooftop, I realised there was no one resource that could answer all of the questions I had about installing solar power.

In particular, I found it hard to find the all-important information on the cost, savings, energy and environmental benefits of solar power. The calculators that were online delivered some of this information, however, most produced biased and unrealistic results in the hope of generating new business. No one calculator was able to incorporate all of the different variables and other important factors including: daily supply charge, the effect of shading and the new solar frontier, battery storage. And so Solar Calculator was born to answer all of these questions and many more; and provide an independent, reliable and accurate resource for anyone wanting to go solar.
