About Us

Ohm Equity was built because choosing between energy upgrades shouldn't require a spreadsheet and an engineering degree. Solar panels, heat pumps, batteries, EVs, insulation — each one has different costs, savings, incentives, and payback periods. We built a tool that does the maths for you.

What we do

We model every major residential energy upgrade and rank them by financial return using net present value analysis. We factor in your location, climate zone, energy rates, government incentives, and home characteristics to give you a personalised upgrade roadmap.

Our principles

  • Independent: We don't sell solar panels, batteries, or any products. We have no affiliate relationships with installers.
  • Transparent: Every assumption is visible and adjustable. We show our working.
  • Privacy-first: All calculations run in your browser. We never see your data.
  • Free: The calculator is free to use, no sign-up required.
