Solar Panel Output Calculator
Estimate your annual solar generation, savings on electricity bills, and payback period based on your system size and location.
Solar Energy Explained
Peak Sun Hours
Peak sun hours is not total daylight — it's the equivalent hours of full-intensity (1000 W/m²) sunlight. UK average: 2.5–3.5 hours. Southern Europe: 4.5–5.5 hours. Middle East/Australia: 5.5–7 hours.
Self-Consumption vs Export
The saving depends on how much generated electricity you use directly. Daytime home users benefit most. Adding battery storage increases self-consumption to 60–80% vs 20–40% without batteries.
Government Incentives
Many countries offer feed-in tariffs, smart export guarantees, or tax incentives for solar. In the UK, the Smart Export Guarantee pays for excess electricity exported to the grid. These significantly improve payback periods — always check current rates.
