Estimate: daily output = total power (Wp) × equivalent sun hours × 0.70 (the yield used for a nomadic panel, poorly angled and without solar tracking, outside the scope of an optimised fixed installation). Sun hours and the electricity price are market averages, to be adjusted to your region and supplier. Calculation horizon fixed at 10 years.
Sunlight: European solar irradiation maps (bands by climate zone). Electricity price: readings taken on 28 August 2026 (suppliers and national regulators).
