REC Group is a premium panel maker, founded in Norway and headquartered in Singapore, that has built a loyal following in Ireland. Here's our independent review of REC solar panels, covering the flagship REC Alpha Pure-RX heterojunction (HJT) range, its warranty, and how it stacks up against value brands like LONGi and Jinko. For wider context, see our solar panel cost guide.
Quick Answer
REC solar panels are a premium choice for Irish homes. The flagship REC Alpha Pure-RX uses lead-free heterojunction (HJT) cells, reaching around 22.6% efficiency at 450-470W in a compact panel. Its standout feature is an industry-leading temperature coefficient near -0.24%/degC plus strong low-light performance, both well suited to Ireland's variable weather. The standard 20-year product and 25-year performance warranty extends to 25/25/25 via REC ProTrust when fitted by a certified installer. You pay a premium over LONGi and Jinko.

REC Alpha Pure-RX: The Panel Range
The REC Alpha Pure-RX is REC's premium residential panel, using lead-free heterojunction (HJT) cells in a compact form factor. It is designed to fit more power onto a typical Irish roof while delivering best-in-class temperature and low-light behaviour.
REC Alpha Pure-RX
The flagship HJT panel, typically around 450–470W and roughly 22.6% efficiency. The model most Irish installers offer when you ask for REC.
Compact Form Factor
REC keeps the physical panel relatively small for its power class, which helps fit more capacity onto compact or awkward Irish roofs.
REC ProTrust Coverage
When installed by an REC Certified Solar Professional and registered, the panel qualifies for the extended 25/25/25 product, performance and labour warranty.

Verdict: REC's HJT cells give it the best temperature coefficient and the lowest degradation rate of the three, which means more output on warm days and stronger long-term yield — genuinely useful in Ireland's variable climate. LONGi and Jinko counter with longer 30-year performance warranties and notably lower prices. If you want the best engineering and a premium installer-backed warranty, REC wins. If you want the best value per kilowatt, LONGi or Jinko are hard to beat.
REC Solar Panels: Frequently Asked Questions
Are REC solar panels good for Ireland?
Yes. The REC Alpha Pure-RX uses heterojunction (HJT) cells with an industry-leading temperature coefficient of around -0.24%/degC and strong low-light performance. Both traits suit Ireland's mild, cloudy climate, where panels rarely run hot but often work in diffuse light.
What is the REC Alpha Pure-RX?
It is REC's flagship residential panel, built on lead-free heterojunction (HJT) cell technology. It delivers around 22.6% efficiency at roughly 450-470W in a compact form factor, making it easy to fit good capacity onto a typical Irish roof.
What warranty do REC panels come with?
REC panels come with a standard 20-year product and 25-year performance warranty (around 92% output at year 25). This extends to 25/25/25 (product, performance and labour) under REC ProTrust, but only when installed by an REC Certified Solar Professional and registered.
How does REC compare to LONGi and Jinko?
REC's HJT cells give the best temperature coefficient and lowest degradation, so they hold output better in warm, variable conditions. LONGi and Jinko offer longer 30-year performance warranties and lower prices. REC is the premium pick; LONGi and Jinko are the value picks.
Can I get the SEAI grant on a REC solar system?
Yes. The SEAI solar PV grant of up to 1,800 euro applies regardless of panel brand, provided the work is done by an SEAI-registered installer. REC systems also benefit from 0% VAT on domestic solar and let you earn the Clean Export Guarantee for power sent to the grid.
