Installation Notes from Our Crew

Q CELLS Q.PEAK DUO BLK ML-G10+ 415W

This is our bread-and-butter panel. The standard size makes racking straightforward and we rarely need custom configurations. Q CELLS has the best domestic supply chain — we almost never face backorder delays. Crew installs average 15-20 panels per day with this model. Rated for 5400 Pa snow load and 4000 Pa wind load — ideal for New England.

REC Alpha Pure-RX 470W

REC Alpha Pure-RX is our go-to premium panel. The 470W output means fewer panels for the same system size, which reduces racking hardware and labor. HJT cells have near-zero LID (light-induced degradation), so these panels produce at full rated power from day one. We recommend REC for space-constrained roofs where every watt per square foot counts.
