AIKO Solar Review (Philippines): ABC Cells at the Top of the Efficiency Table
Published specifications for the Neostar 2S / 2P (ABC). A brand ships several series, so these figures describe this model and not every product the manufacturer sells.
- Rated power
- 440–520 W144-cell formats run to 610 W in the larger frames.
- Module efficiency
- Up to 23.5–24.3%Neostar 2P54 to 24.3%, 2S60 to 23.5%. AIKO markets the ABC range at roughly 25% at its ceiling; the datasheets for these residential models are a little below that.
- Cell technology
- N-type ABC (All Back Contact)Contacts sit on the rear, so nothing on the front face shades the silicon.
- Product warranty
- 15 yearsExtendable to 25 on some models, and some variants ship at 25 as standard. Confirm which applies to the model quoted.
- Performance warranty
- 30 years, linear
- Annual degradation
- 0.35% after year oneUnder 1% in year one; about 88.85% remaining at year 30.
- Temperature coefficient
- −0.26 %/°CTied with LONGi Hi-MO for the best figure among the panels compared here.

What it does well
- The highest module efficiency in this comparison at 23.5–24.3%, so a target system size fits in noticeably less roof area.
- Back-contact cells change how the module behaves under partial shade, which is the claim most likely to matter on a cramped roof with a water tank or a neighbour's wall.
- A certified Philippine distributor, EcoSolutions, rather than assorted marketplace listings.
Where it falls short
- A single certified distributor is a starting point, not the installed base Jinko, Trina or Canadian Solar have — and replacement modules for a 2026 ABC product in 2033 is a question worth asking before you buy.
- Fewer local crews have wired an ABC array, so installer familiarity is thinner than for mainstream TOPCon.
- Efficiency solves a roof-area problem. On an open, generously sized roof the premium buys a spec that does not change your bill.

Dashes are figures the manufacturer does not publish, not zeros. Where two products differ on a spec, which one matters depends on your roof and your usage — a higher efficiency panel earns its premium on a small roof and rarely on a large one.
AIKO is a Chinese manufacturer that took a different route to high efficiency than the rest of the market. Where most premium brands iterate on TOPCon, AIKO built its residential range around ABC — All Back Contact — which moves the electrical contacts to the rear of the cell. Nothing on the front face shades the silicon, and the panels reach roughly 25% module efficiency, currently the top of the mass-production table.
For a Philippine buyer the question is not whether the technology is good. It is whether you need it, and whether the local channel is deep enough to stand behind a 15-year product warranty.
Lineup and specs
The residential range is N-type ABC, sold in the 450Wp-and-up class, with 144-cell formats running to 610W in the larger frames. Two properties matter more than the headline efficiency number:
- Shading behaviour. Removing front-side contacts and busbars changes how the cell responds to partial shade. AIKO markets this as its main practical advantage, and on a cramped Philippine roof with a water tank, a vent stack or a neighbour’s wall throwing afternoon shade, it is the claim most likely to matter to you.
- Efficiency per square metre. At ~25%, an AIKO array reaches a target kW in noticeably less roof area than a mainstream 21-22% panel. That is the real reason to pay for it — see how much roof space solar panels need.
If your roof is large and unshaded, that premium buys you very little. Panel wattage and efficiency decide panel count and area, not system output — the wattage guide covers why.
Warranty
AIKO publishes a 15-year product warranty and a 30-year linear performance guarantee on its ABC line. The 15-year product term is longer than the 10-12 years most mainstream brands offer, and the 30-year performance curve is at the generous end of what anyone publishes.
Read that in context. A warranty is a claim against a company through a local channel, over a period longer than many solar companies have existed. See solar panel warranties explained for what actually gets honoured.
Local availability
EcoSolutions is the certified AIKO distributor in the Philippines. That is a real, named channel rather than assorted marketplace listings, which puts AIKO ahead of most newer entrants here.
It is still a single distributor. Compare that with Jinko, Canadian Solar or Trina, which most Philippine installers have quoted, wired and serviced many times over. Fewer local crews have handled an ABC array, and replacement modules for a 2026 ABC product in 2033 are a question worth asking your installer directly.
What AIKO panels cost in the Philippines
We don’t publish a per-panel sticker price, and marketplace listings for a brand this new here are not a reliable basis. What matters is installed cost, and Philippine systems run ₱45,000-75,000 per kW installed across the market — the solar panel price list has the full table by size.
AIKO sits at the premium end of that band. The honest way to evaluate it is peso per watt against a mainstream Tier-1 quote for the same kW. If ABC costs meaningfully more per watt and your roof has room to spare, the mainstream panel is the better buy. If you are area-constrained and cannot fit your target system any other way, the efficiency is worth paying for.
Where it falls short
- Channel depth. One certified distributor is a starting point, not the installed base that Pylontech-style ubiquity gives you on servicing.
- Installer familiarity. ABC is not electrically exotic, but it is not what most local crews have been fitting for the last five years.
- Premium you may not need. Efficiency solves a roof-area problem. If you don’t have one, you are paying for a spec that does not change your bill.
Who it’s best for
Buyers with limited or shaded roof area who need maximum kW from the space available, and who are comfortable buying through a single distributor. If your roof is open and reasonably large, a Tier-1 mainstream panel at a lower peso per watt will produce the same system output for less money.
