The Infinity RT series uses N-type TOPCon cells with 22.3% efficiency, 25-year product warranty, and 30-year performance guarantee, matching mainstream brands.

DMEGC solar panels review: are they worth it?
SolarInfo.uk editorial rating (out of 5)
Spec-for-spec identical to Jinko and JA Solar (22.3% efficiency, N-type TOPCon, 25-year product and 30-year performance warranty) at a 3 to 8% lower price, from a Bloomberg NEF Tier 1 maker. Marked down only for lower UK brand recognition and a smaller installer network than Aiko, Jinko or LONGi.
Worth it if your installer already sources DMEGC and you want mainstream-grade panels for a little less. Look elsewhere if you want the highest-efficiency panel on the market (see Aiko) or maximum brand resale value (LONGi).
Who are DMEGC?

On paper DMEGC is essentially identical to Jinko and JA Solar: same 22.3% efficiency, same N-type TOPCon cells, same warranties, at a slightly lower price. The panel that genuinely separates itself is Aiko, whose ABC (All Back Contact) cells push efficiency to around 23.6% with no front-side busbars, so they generate a little more per square metre and shrug off partial shading better. You pay a clear premium for it.
DMEGC vs Aiko in one line: Aiko wins on efficiency and shade tolerance for a tighter or partly shaded roof; DMEGC wins on value when roof space isn't the constraint. If your roof is large and unshaded, DMEGC's cheaper watts are the smarter buy; if space is tight, Aiko's extra output can be worth the premium.
