Section 1 · The Founder's Letter

From Trade Secret to Industry Standard.

YA Yousri AbdouFounder, SolarProforma.ai · 20 years C&I solar

If you have ever lost a commercial solar deal because your financial model broke during a CFO presentation, I know exactly how you feel.

I am a 20-year veteran of the commercial solar industry. Over the last two decades, I have developed, acquired, and managed multi-million dollar solar portfolios. Early in my career, I realized that the companies winning the biggest deals weren't necessarily building better arrays — they were building better financial models.

So, I built my own. I spent years perfecting our excel spreadsheet that could instantly calculate complex tax waterfalls, handle MACRS depreciation, and accurately model structures like Prepaid and Hybrid PPAs. It became the backbone of my entire business. It was my "secret sauce," and for years, I guarded my formulas and know-how closely. I was reluctant to share the exact math that could give my firm such a massive competitive edge.

But as the commercial solar industry grew, I watched brilliant developers and EPCs struggle. I saw great projects die on the vine because teams were fighting with broken spreadsheets instead of closing deals. I realized that hoarding this knowledge wasn't helping the industry scale to meet the massive demand for clean energy.

I originally created this app to be my own ultimate decision-making tool. Today, SolarProforma.ai is available to the entire solar community. We took 20 years of hard-won financial engineering and wrapped it in a beautifully simple, CFO-ready platform.

We are here to help you stop modeling, and start closing.

“SolarProforma.ai replaced a model my team spent three days a week maintaining. The 30-year output matches our auditor's spreadsheet — to the dollar.”

Every release is regression-tested against an industry benchmark. If the IRR moves by even 0.01%, the deploy fails.

Section 2 · Our Values

Four principles, no compromises.

1. Built by Developers, for Developers

We aren't Silicon Valley tech bros guessing how a solar PPA works. We are industry veterans who have sat across the table from Tax Equity investors and commercial CFOs. We deeply understand your pain points because we lived them.

2. Bankable Accuracy

In project finance, a rounding error can cost millions. We don't do "back of the napkin" math. We demand institutional-grade excellence in our algorithms so you can walk into any boardroom with absolute confidence in your numbers.

3. Transparent Math

We hate "black box" software. While our interface is simple, we believe you should always be able to audit the math. We maintain radical transparency so your internal teams and external financiers can trust the tax models.

4. Simplicity at the Surface

Tax code is incredibly complex; your software shouldn't be. We do the heavy lifting of interpreting IRS Safe Harbors and depreciation schedules in the background, providing you with a seamless, intuitive UI that anyone on your sales team can master.
