Solar PV Optimizer
Site-level photovoltaic yield, payback and ROI optimization for rooftop, carport and ground-mount solar arrays.
Site-level solar yield, payback and ROI optimization
Solar PV Optimizer turns a site into a bankable solar business case. It combines irradiance data, roof and land geometry, shading, module technology and tariff structure to compute annual yield, performance ratio, payback and lifetime ROI — then searches configurations to find the layout that maximises return rather than raw capacity.
Key capabilities
Hourly irradiance, tilt, azimuth, albedo and soiling losses rolled into an annual energy figure.
CAPEX, OPEX, tariff, self-consumption ratio and export caps produce payback, IRR and NPV.
Rooftop, carport and ground-mount mixes are compared automatically for best return per m².
Avoided CO₂ per year, aligned with reporting frameworks.
Use cases
- Commercial rooftop screening
Rank an entire property portfolio by solar ROI before commissioning any site survey.
- Utility-scale prefeasibility
Test land parcels against grid connection limits and tariff scenarios.
- Green financing
Produce the yield and carbon evidence lenders require for sustainable finance.
Frequently asked questions
How is payback calculated?
Payback uses modelled annual yield, the self-consumption share at your tariff, export revenue subject to grid caps, and full lifecycle CAPEX and OPEX.
Can it model battery storage?
Yes. Storage is evaluated when export caps or tariff spreads make it economic, and its effect on payback is shown separately.
What irradiance data is used?
Satellite-derived long-term irradiance series for the site coordinates, corrected for local shading and soiling.
Does it handle bifacial modules?
Yes — bifacial gain is modelled from ground albedo and mounting height, typically adding 4–8% yield.
