Solar / BIPV ROI & Yield Calculator + Custom API DevelopmentTinashe Nedi
Engineering-grade solar and BIPV tools built for accuracy and real-world use — not simplified estimates.
I create custom web calculators, APIs, and analysis tools that deliver trustworthy results for solar installers, facade engineers, developers, and sustainability consultants.
What you get:
Instant solar ROI & savings calculators (payback, annual production, 25-yr cashflow) using PVWatts physics and traceable data
BIPV energy yield modeling (kWh, LCOE, NPV, IRR, CO₂ reduction) with NASA POWER irradiance and tropical/urban adjustments
BIPV structural load analysis (wind/dead loads, pressure equalisation, ULS combos, fixing forces) compliant with EN 1991 & ASCE 7-22
EV + solar integration feasibility (extra panels, fuel savings, charging windows)
Professional PDF reports with charts, tables, and methodology notes
Live API playgrounds for instant testing and integration
Full source code, clean documentation, and deployment support
All work is auditable, standards-compliant, and ready to deploy — helping you win projects, convert leads, and maximize client savings.
Perfect for C&I feasibility studies, BIPV facade design, or bundled solar+EV solutions.
Let's build your next high-value energy tool.
FAQs
PVWatts/NREL for production, EN 1991 & ASCE 7-22 for structural loads, IEC/EN for yield, NASA POWER for irradiance, IRA/DSIRE for incentives.
Yes — full source code handover with every project (clean, documented, ready to deploy).
Yes — I provide access to live API playgrounds and demo calculators during discovery.
2–6 weeks depending on scope (basic calculator: 2–3 weeks; full BIPV suite: 4–6 weeks).
Yes — 1-month support included on premium packages; longer maintenance available.
