ONE ROOFTOP, MEASURABLE IMPACT
From sunlight to a decision, in one line.
Capacity drives generation. Generation drives savings, payback, and avoided emissions.

THE DECISION REPORT
One report. Nothing hidden behind it.
Live, location-specific yield
Monthly production from PVGIS for your exact coordinates.
Sized to demand, capped by roof
Your bill sets the target; your roof sets the limit.
Every assumption editable
Panels, losses, degradation, and emission factor stay in your hands.
Demand-matched system within roof capacity.
HOW IT WORKS
Locate. Model. Decide.
- 01
Locate
Search a city or district; coordinates come from Open-Meteo.
e.g. Maltepe → 40.94° N, 29.16° E
- 02
Model
Roof, bill, tariff, and cost meet live PVGIS production.
Roof area · Bill · Tariff · Cost/kWp
- 03
Decide
Read size, savings, payback, and emissions in one report.

SOLARSCOPE IN USE
60 people. 10 cities. One clearer path to solar.
From Istanbul to Bremen and Seattle, people used SolarScope to turn their own roof, energy, and location data into clear system, savings, payback, and environmental outcomes.

What users said
SolarScope helped me assess both the financial return and the environmental contribution of installing solar panels. I have already recommended it to my colleagues.
Seeing the payback period and estimated first-year savings made the decision much clearer for me.
Being able to see the 25-year financial outlook was especially valuable. The tool answered my questions and served its purpose clearly.
It gave me a practical way to evaluate the energy-system investments I plan to make.
An excellent project.
A remarkably smart renewable-energy application. It will be useful to me, and I congratulate Kerem on creating it.

Energy made measurable
Location-specific production translated into system size, generation, savings, and payback.
Impact made visible
Estimated clean-energy production translated into avoided emissions and illustrative tree equivalents.
Built on public data. Designed for transparent decisions.
Assumptions stay editable and every formula is documented. Educational estimates only—not engineering, financial, or installation advice.
