Esse Solar vs AKCOME - solar panel manufacturer comparison

Esse Solar and AKCOME represent two very different tiers of market participant. Esse Solar, founded in 1991 and headquartered in Gallarate, Italy, operates as a small solar solutions provider and systems integrator with between 11 and 50 employees. The available data contains no proprietary panel portfolio for the company - zero panels on record, no published wattage figures - which is consistent with its role as a distributor and installer rather than a volume module manufacturer. AKCOME, by contrast, is a Chinese manufacturer founded in 2003 that has built a focused product line around heterojunction (HJT) technology and competes directly in the premium module segment. AKCOME does not currently appear on the Bloomberg NEF Tier 1 bankable module makers list, so both companies lack the institutional backing that large project financiers typically require.

On product portfolio, the contrast is stark. Esse Solar has no documented proprietary panel lineup, making a technical comparison of module specifications essentially one-sided. AKCOME's three-panel catalogue is 100% bifacial and 100% HJT, averaging 671.67 Wp per panel and reaching a maximum of 700 Wp. Average panel efficiency sits at 21.63%, with a top figure of 22.54% - both figures competitive within the HJT segment. The average temperature coefficient of -0.24%/degree C is notably low, a characteristic advantage of HJT cells in warm climates where most panels lose output faster as temperatures rise. AKCOME backs its modules with an average warranty of 30 years. This profile targets utility-scale and large commercial ground-mount installations where high per-panel output, bifacial rear-side gain, and thermal stability materially affect yield projections.

For a typical buyer in 2025, AKCOME is the only credible choice between the two if the goal is procuring solar modules directly. Esse Solar functions as a regional Italian integrator, useful for turnkey project delivery in its local market, but it is not a module manufacturer a buyer elsewhere can source from. AKCOME's HJT bifacial lineup is technically strong, though the absence of Tier 1 bankability status is a meaningful caveat for project-financed installations where lender approval of the module brand is a contractual requirement.
