No BloombergNEF listing, no module datasheet, and no production capacity data exist for an "ENCOR" panel brand. I'll write an honest comparison reflecting this finding. \--- AIKO is a Chinese solar panel manufacturer headquartered in Guangzhou, founded in 2009. It has established itself as a genuine module producer, achieving BloombergNEF Tier 1 status in Q3 2024 - a recognition held by roughly the top 2% of solar companies globally, based on demonstrated non-recourse project financing across multiple banks. By early 2025, AIKO's production capacity was reported at approximately 20 GW per year, placing it among the larger-scale Chinese manufacturers, and further expansion was underway. On institutional footprint, AIKO is clearly the more established entity of the two names presented here. ENCOR, by contrast, could not be confirmed as a solar panel manufacturer through any credible industry source. Web searches consistently surface "Encor Solar LLC," a US-based residential solar installer headquartered in Lehi, Utah, which does not manufacture its own modules and has been reported as no longer in operation. No ENCOR-branded module datasheet, cell technology specification, or BloombergNEF listing was found. It is possible the name refers to a niche regional brand not yet indexed by major industry databases, but no evidence supports treating ENCOR as a comparable manufacturing peer to AIKO. For any buyer evaluating panels in 2025, AIKO is the only one of these two names that can be assessed with confidence. Its ABC (All-Back-Contact) cell technology delivers panel efficiencies above 24%, low temperature coefficients, and strong long-term degradation warranties, making it a credible choice for premium residential rooftops or space-constrained commercial installations. A direct comparison with ENCOR is not possible given the absence of verifiable product data for that brand - buyers should confirm with their installer exactly which manufacturer is behind any panel sold under that name. \---LINKS--- \- https://aikosolar.com/en/aiko-achieves-prestigious-tier1-status/ \| AIKO achieves BloombergNEF Tier 1 status - official announcement \| article \- https://www.solarquotes.com.au/panels/aiko-solar-review.html \| Aiko Solar panels review - SolarQuotes \| review \- https://www.raylyst.eu/en/what-distinguishes-aiko-abc-technology-from-perc-topcon-or-hjt-panels/ \| What distinguishes AIKO ABC technology from PERC, TOPCon or HJT \| article \- https://www.energysage.com/supplier/23211/encor-solar/ \| Encor Solar profile and reviews - EnergySage \| review \- https://www.vicoexport.com/en/67499/tier-1-list-of-solar-panel-manufacturers-q2-2026/ \| Tier 1 solar panel manufacturers list Q2 2026 \| article Written by claude-sonnet from the figures above. ## Other comparisons - [ENCOR vs A.B.
