SP Enerji vs AKCOME - solar panel manufacturer comparison

AKCOME, founded in 2003 and headquartered in China's Jiangsu Province, is a specialist in heterojunction (HJT) cell technology with reported ambitions to build multi-gigawatt HJT production capacity. SP Enerji, founded in 2008 and based in Turkey, operates a 1.2 GW PERC manufacturing facility and serves primarily the Turkish and regional European markets. Neither manufacturer currently holds Tier 1 BNEF bankability status - a meaningful distinction since project finance lenders typically require Tier 1 designation before approving non-recourse loans. AKCOME's situation is further complicated by a bankruptcy filing at one of its subsidiaries in 2024, which adds measurable counterparty risk for buyers considering long-term warranty exposure. SP Enerji's regional production base gives it a more predictable institutional footprint for European procurement channels.

The two lineups differ substantially in portfolio character. AKCOME's three catalogued panels are all bifacial HJT modules averaging 671.7 Wp and peaking at 700 Wp, with average efficiency of 21.6% and a maximum of 22.54%. The standout metric is the temperature coefficient of -0.24%/degree C per Pmax - among the best available on the market - paired with a 30-year product and performance warranty. This positions AKCOME squarely at the premium end: large-format, high-density utility-scale or rooftop-commercial arrays where energy yield per panel justifies a higher module cost. SP Enerji's 33-panel PERC lineup tells a different story: average output of 333.6 Wp, a maximum of 410 Wp, average efficiency of 18.6% topping out at 20.67%, and a temperature coefficient of -0.39%/degree C. Only one-third of its portfolio is bifacial, and warranty terms run to 25 years. That profile fits standard residential rooftops and small-to-mid commercial installations where conventional panel sizes and competitive pricing matter more than peak performance.

For a typical buyer in 2025, SP Enerji is the lower-risk default for residential and light commercial projects in Turkey or nearby markets, given its broader product range, local supply chain, and absence of the financial turbulence shadowing AKCOME. Buyers targeting high-density utility or large commercial systems and willing to absorb the bankability risk may find AKCOME's HJT efficiency and temperature performance compelling - but should secure robust contractual protections given the manufacturer's current instability.
