Why most solar calculators miss the mark
Typical calculators are built by installation companies, meaning:
-
They might only show results that favour their product or funding model.
-
They use generic assumptions that don’t reflect your actual operating hours or energy profile.
-
They skip over viability challenges that could derail your project later.
Our Feasibility Kickstarter tool solves these problems by being:
-
Independent: we’re not here to sell panels.
-
Business-focused: everything is optimised for your ROI and operational impact. Just like what Optify does with clients, our tool is working on your behalf to find the best outcome for you.
-
Comprehensive: the tool covers funding, savings, and readiness all in one verdict.
Enter key details: tell us about your energy use, roof space, and site type.
Run the model: our system calculates savings, compares funding models, and factors in your readiness for renewable energy.
Get your verdict: see a clear assessment of:
-
Your potential annual and lifetime savings.
-
ROI projections and payback timeline.
-
Whether now is the right time to proceed.
-
See if your project could qualify for battery storage to be included at no additional cost.
Next steps, if you’re ready: if you choose, we can then undertake a full feasibility study for you, based on accurate consumption data and a site specific draft solution design and fully costed funding options for you to consider. Again, this exercise is conducted exclusively as an exercise in proving the business case for you and getting the very best outcome possible for you, on affordability and ROI grounds. Our objective is to show you a solution that pays for itself and then delivers industry leading lifetime savings.

Solar panel calculator for businesses: a complete guide to renewable energy viability
Most “solar panel calculators” online give you a rough guess at costs and savings. They rarely consider your unique energy profile, funding options, or the actual business case.
That’s where our Feasibility Kickstarter tool is different. It’s the only UK tool designed for commercial decision makers that:
-
Calculates potential energy savings based on your real usage.
-
Compares funding models like purchase, lease, and PPA to determine the best-fit for your circumstances, contributing to optimised financial performance.
-
Shows projected ROI and payback period.
-
Highlights viability risks before you commit.
-
Determines a project structure based on getting the best project outcome for you.
-
Focuses on establishing project viability for you and not on getting a sale for an installer.
-
Provides vital input for you to make the strongest business case possible for renewable energy for your business.
-
Signals special offers that we’re able to make on an exclusive basis, like getting battery storage included in the project at no additional cost, available if certain project criteria are met, further enhancing the ROI from Optify projects.
And because we’re independent, the results are 100% geared in your favour, not an installer’s sales target.
