How to Choose the Right Solar Panel
Consider these factors:
1. Roof Space
Smaller roofs require higher-efficiency panels.
2. Budget
Budget buyers may prefer polycrystalline.
Premium buyers should choose TOPCon.
3. Warranty
Look for at least:
- 25-year performance warranty
- 15–30-year product warranty
4. Efficiency
Higher efficiency provides greater long-term savings.
5. Brand Reputation
Choose manufacturers with:
- Proven track record
