17 Insider Tips to Save Thousands on Your Solar Installation

May 9, 2026Panel efficiency has crossed 25% for the leading products — meaning more power from the same roof space. Here’s what that means in practice and which panels Jon recommends for NJ homes.
Why Efficiency Matters (And When It Doesn’t)
Higher efficiency panels produce more watts per square foot. If your roof space is limited, efficiency matters a lot — a 25% efficient panel fits more power onto a small roof. If you have ample south-facing roof space, efficiency matters less than price per watt and long-term warranty quality.
REC Alpha Pure
Jon’s most-installed premium panel. Excellent temperature coefficient (better performance on hot days), strong 25-year warranty, and proven field reliability. Efficiency in the 22–23% range with some newer variants pushing higher. Made by a company with a long track record.
QCell Q.PEAK DUO
The value pick for quality. Solid efficiency (21–22%), excellent warranty, and competitive pricing. Made in Georgia, USA (some models). Jon installs these on projects where REC is beyond the budget without compromising on quality.
Silfab Elite
Canadian manufacturing, strong in cold-weather performance. Good temperature coefficient and 30-year power warranty on some models — the longest in the industry. Worth considering for NJ’s variable climate.
Canadian Solar HiHero
Pushing toward 23–24% efficiency. Strong value proposition at this efficiency level. Long track record in commercial solar brought to residential.
What to Avoid
No-name panels from manufacturers without a 10+ year track record. The panel warranty is only as good as the company backing it. SunPower, despite name recognition, has had significant business stability issues — verify carefully before proceeding.
The Bottom Line
For most NJ homes: REC Alpha or QCell. The efficiency race matters at the margins — warranty, manufacturer stability, and installer quality matter more.
