It depends on your energy usage. For a typical US home with a $200/month electric bill, you'd need about 20 panels (430W each) for an 8 kW system. Use our quick estimate tool for a personalized calculation.
The Alpha Pure-R 430W has a module efficiency of 22.3%, which means it converts that percentage of sunlight into electricity. This is above average for residential solar panels.
REC offers a 25-year product warranty and 25-year performance warranty. Annual degradation is guaranteed not to exceed 0.25%.
Key strengths: Best temp coefficient -0.24%/C, HJT technology, lowest degradation 0.25%/yr, lead-free/RoHS, premium build. Considerations: Higher price point, 20yr product warranty (vs 25yr competitors), slightly different cell count 132. It's a solid premium option from a Tier-1 manufacturer.
