An average over a catalogue describes the range a manufacturer publishes, not the module you would buy. A brand with two flagship panels and eighty older ones averages worse than one that has retired its back catalogue.

Written summary

Checking cache...

ENCOR Solar is a US-based solar installation company - not a panel manufacturer - that was headquartered in Lehi, Utah, and operated primarily across the American Southeast and Midwest. Founded as a residential solar sales and installation firm, it sold and installed third-party panels rather than producing its own, and it never appeared on BloombergNEF Tier 1 bankability lists. The company abruptly ceased operations in early 2024 amid financial difficulties, leaving hundreds of customers with unfinished or non-operational systems and triggering a consumer-protection investigation by the North Carolina Attorney General's office. Hyundai Energy Solutions, by contrast, is an established South Korean panel manufacturer whose solar division was launched in 2004-2005 as part of the broader Hyundai Heavy Industries group. While Hyundai Energy Solutions has not been confirmed on recent BloombergNEF Tier 1 lists by the sources reviewed, the company's backing by a globally diversified industrial conglomerate gives it substantially stronger institutional and financial standing than ENCOR ever had. On institutional footprint, there is no close comparison.

Hyundai Energy Solutions produces two main residential product lines - the XG Series, a conventional mono-crystalline rooftop panel, and the YH Series, a bifacial format better suited to ground-mounted or dual-exposure rooftop applications. Reported efficiency ratings for the XG line run in the 19.2-20.6 percent range and some newer models are associated with N-type TOPCon cell technology. Both lines carry a 25-year product and performance warranty. ENCOR Solar had no proprietary panel products; as an installer it bundled whatever manufacturer panels it had sourced, so a direct technology comparison is not meaningful.

For any buyer in 2025, ENCOR Solar is simply not an option - the company is defunct and its warranties are effectively unenforceable. Hyundai Energy Solutions panels, available through independent installers and distributors, represent a solid mid-tier choice for residential and light-commercial rooftop projects, offering above-average efficiency and the credibility of a large corporate parent at pricing that tends to undercut premium brands. Buyers should confirm local availability and installer support, as Hyundai Energy Solutions has a more limited US distribution footprint than dominant Chinese manufacturers.
