Solar power converts sunlight into electricity using solar panels, then stores and delivers that energy through a small set of core components. This site focuses on fundamentals: how systems work, how to size them, and what matters in real-world performance.
Wh
System Sizing
Start with daily energy use (Wh). Then size battery and panels correctly.
Capacity
Solar Batteries
Storage types, usable capacity, and what matters in practice.
How a basic solar power system works
A functioning solar power system is usually built from four main building blocks:
- Solar panels produce DC electricity from sunlight.
- Charge controller manages battery charging and prevents overcharge.
- Battery storage stores energy for evenings and low-sun periods.
- Inverter converts DC (battery) into AC power used by common household devices.
What matters in real-world performance
- Sun hours and season: output varies throughout the year.
- Shading: small shadows can reduce production significantly.
- Panel angle and temperature: mounting and heat affect yield.
- Battery sizing: storage determines how long you can run loads without sun.
- Inverter selection: continuous watts and surge capability must match your loads.
