There is no universal panel count for every home. Two houses of the same size may need very different systems when their habits and electrical equipment differ.
The four main factors
- Annual energy usage measured in kWh.
- Panel power and efficiency.
- Solar hours and local climate.
- Roof space, orientation, and shade.
Designing for actual usage
The goal is to produce the right amount of energy for your usage profile, not to fill the roof. A technical visit validates measurements, structure, electrical paths, and possible shade.
