How It Works

I built this because I got tired of building Excel models from scratch every time I needed to price a PPA.

Why I Built This

Look, I work in renewable project finance and I was spending way too much time building Excel models from scratch. Every project needed the same basic calculations, but I kept recreating the wheel.

So I built this. It's not fancy, but it works. You get a decent Excel model in minutes instead of hours. No more wrestling with IRR formulas or trying to remember how to calculate LCOE.

Simple Inputs

Enter your system size, costs, and project parameters. Our calculator handles the complex financial modeling behind the scenes.

Excel Export

Get a complete Excel model with cashflows, KPIs, and all the details your partners expect. No proprietary formats.

Industry Standard
