Panel types
There are three panel types on the market: monocrystalline, polycrystalline, and thin-film. For residential systems, monocrystalline panels are the best choice: higher efficiency, better performance in cloudy conditions.
Inverter selection
The inverter converts DC to AC power. Two main types:
- String inverter: cheaper, simpler, ideal for smaller systems
- Microinverter: one per panel, advantageous for roofs with shading
Sizing basics
System size is determined by monthly electricity consumption. General guidelines:
- 300 kWh/month → ~3-4 kW system
- 500 kWh/month → ~5-6 kW system
- 800+ kWh/month → ~8-10 kW system
