What Solar Professionals Say
The financial modeling alone justified the switch. Our proposals now include detailed ROI projections that homeowners actually understand and trust.
Mike Rodriguez
Owner, Lone Star Solar · Texas-based residential & C&I
"We closed 12 more C&I projects last quarter. The investor-grade financials and P50/P90 reports give banks the confidence to fund projects faster."
Ahmed Hassan
Technical Director, Gulf Solar Solutions
"Multi-currency support solved a major pain point for our international projects. We model tariffs in EUR, USD, and AED from one platform."

What is a bankable solar energy report?
A bankable solar energy report is a document that lenders and investors use to evaluate project risk and expected returns. It includes P50/P90 yield forecasts, weather-adjusted performance models, and detailed loss budgets. SurgePV generates these reports with \u00b13% accuracy, accepted by financiers in 18+ countries.
What do P50 and P90 mean in solar energy modeling?
P50 is the median annual energy yield \u2014 the amount the system is expected to produce 50% of the time. P90 is the conservative estimate \u2014 the yield exceeded 90% of the time. Lenders typically require P90 reports to ensure debt coverage even in low-production years. SurgePV generates both from shading analysis and weather data automatically.
What financial metrics do solar investors look for?
Solar investors focus on IRR (Internal Rate of Return), NPV (Net Present Value), payback period, and LCOE (Levelized Cost of Energy). SurgePV calculates all of these from the system design and feeds them directly into the proposal \u2014 no spreadsheets or manual calculations needed.
Frequently Asked Questions
How accurate are the energy yield forecasts?
SurgePV delivers ±3% accuracy compared to field measurements, using TMY weather data and comprehensive loss modeling. Reports are validated against real-world production data across hundreds of installed systems.
Can I model different financing structures?
Yes. SurgePV supports cash purchase, loan, lease, and PPA financial models with fully customizable terms, interest rates, and escalation factors. Compare all structures side-by-side in one proposal.
Do banks accept SurgePV financial reports?
Yes. P50/P90 energy reports and investor-grade financial summaries meet financing standards used by banks and solar project investors globally. EPCs across 18+ countries have successfully funded projects using SurgePV outputs.
Does it support international tariff structures?
Yes. SurgePV supports multi-currency financial modeling, net metering, feed-in tariffs, time-of-use rates, and region-specific incentive programs across 18+ countries including UAE, India, UK, Germany, and the US.
How accurate is SurgePV compared to PVsyst?
SurgePV is calibrated to within ±3% of PVsyst for energy yield forecasts. The platform uses the same TMY weather datasets and loss modeling methodology, but integrates the results directly into the design and proposal workflow — eliminating the need to export data between separate tools.
What financial metrics does SurgePV calculate?
SurgePV calculates IRR, NPV, payback period, LCOE, and cash-flow projections for cash purchase, loan, lease, and PPA structures. All metrics are generated from the system design and fed directly into the proposal for client and investor presentation.
