Panels: What Matters
- Cell Type: Mono PERC/Topcon generally higher efficiency than Poly
- Half-Cut & Bifacial: Better performance and lower losses
- Brand & Warranty: Tier-1 brands, 25-year performance, 10–12 year product warranty
- Temperature Coefficient: Lower is better for hot climates
Inverters: Match Your Use
- String Inverters: Cost-effective and reliable for most rooftops
- Hybrid Inverters: Enable battery integration for backup and peak shaving
- MPPT Count: More MPPTs help when panels face different directions
- Monitoring: App-based monitoring to track generation and alerts
For most homes, a mono PERC array with a quality string inverter offers great value. If outages are frequent or backup is needed, a hybrid inverter with Li-ion battery is a smart upgrade.
