Free tools designed for investors, developers and photovoltaic asset managers. From financial analysis to technical sizing.
Full financial analysis: CAPEX, OPEX, BESS, price cannibalization and 30-year cash flows.
TechnicalSize your plant: MWp/Ha, GCR, optimal Pitch for fixed-tilt and trackers.
TechnicalMeasure the real efficiency of your solar installation and detect operational losses.
EngineeringConvert W/m² to kWh/m², calculate Peak Sun Hours (PSH) and understand power vs energy.
FinancialCalculate how much you can earn leasing your land for solar energy. Lease or sell?
FinancialBattery economic viability: payback, price arbitrage, aFRR and curtailment capture.
FinancialCompare levelized cost of energy across technologies: PERC, TOPCon, HJT and bifacial.
Unlike simplified calculators, our tools consider the critical variables that affect the real profitability of utility-scale photovoltaic projects: price cannibalization, module degradation, BESS storage, and actual irradiation conditions in Spain.
Start with the Investment Calculator to model cash flows, and complement with the LCOE Calculator to compare technologies.
Use the Density Calculator for sizing and Performance Ratio to validate operational efficiency.
The Land Profitability Calculator will help you decide whether to lease or sell your land.
If you are an investor, start with the Investment Calculator. If you are an engineer, use the Density Calculator. If you are a landowner, the Land Profitability Calculator is your best option.
Yes, all calculators are 100% free and require no registration. You can use them without limits for your photovoltaic project analyses.
LCOE (Levelized Cost of Energy) represents the minimum price at which you must sell electricity to recover the investment. Our LCOE calculator considers CAPEX, OPEX, degradation, and project lifetime.
Performance Ratio is a KPI that measures the real efficiency of a solar plant by comparing generated energy with theoretically possible energy. A typical PR in Spain ranges from 75% to 85%.
Income varies by location, size, and contract terms. In Spain, solar leases typically range from €1,500 to €3,000/Ha/year. Use our Land Profitability Calculator for a personalized estimate.
