Overview of REC Group – Company History

Founded in Norway in 1996, REC Group is one of the original manufacturers of solar photovoltaic modules with a focus on premium quality. Originally production was completed in Norway and Sweden. In 2010 they became fully automated, producing 26 million solar panels in their production plant in Singapore. In 2015 Norway’s Elkem Group (Bluestar Investment Co. Ltd) acquired REC. Elkem is a world leader in silicon production, this has aided the development of REC’s integrated photovoltaics in the global market.

REC Group now has 8 offices across the globe including an Australian office in the Melbourne CBD. The REC Certified Solar Professional Program enables solar installers to become ‘certified’ with them enabling them to offer longer warranty periods to their customers including a product and labour warranty of up to 25 years.

For those looking for an independent REC solar panels review, we’ve done our research and written extensively on this topic:

What is a Bloomberg Tier 1 Solar Panel?

Bloomberg’s infamous tier 1 ranking is NOT a measure of Solar Panel quality. It is just an indication of the bankability of the manufacturer based on publicly released information on the financial health the company. This should give you an idea if the company is a large, well-known manufacturer.

REC Group were ranked on the Bloomberg tier 1 list as of Q4 2020.

What is PV Evolution Labs Top Performer?

PV Evolution Labs with support from DNV GL independently test solar panel reliability. The tests are voluntary, with solar panel manufacturers paying to participate in the testing. This testing process is internationally renowned and is an accurate reflection of the solar panel’s performance.

REC solar panels are currently ranked in the PV Evolution Labs Top Performers across 2 of the 6 annual tests in the latest 2023 report.

Why is office location in Australia Important?

Most solar panel manufacturers entering the Australian market first set up their distribution channels and worry about customer service later. This has led to many unhappy customers who are left trying to contact Chinese head offices to claim on their 10-year product performance warranty.

Relying on your solar installer is not always an option as we’ve seen many residential solar installers (including the large ones) go out of business well within the lifetime of the systems they are installing. 

REC has an Australian office located in Melbourne.

REC Solar Panels – Points of Difference

There are many solar panels out there, what makes REC solar panels stand out?

Long Product Warranty

Now that LG have dropped out of the market, REC is one the leading premium solar panel manufacturers. They aim to lead the market in quality and reliability, and as a result offer an industry leading 25 year product warranty. REC solar panels have been shown to be more resilient in corrosive coastal conditions and are tested independently to higher standards than most panels. For example they have been called a top performer by PV Evolution Labs solar module scorecard.

Lower Degradation Rate

REC’s top quality Alpha Pure series solar panels lose only 0.25% of their power annually after the first year and still retain over 92% of their nameplate value after 25 years. At the time of writing, the only other solar panel on the market to match this degradation rate is the Sunpower Maxeon 5. This means this REC solar panel will deliver significantly more power than other solar panels on the market through the course of its 25-year lifetime. 

REC’s Warranty Offer for Australian Customers

Solar panels in the Australian market come with a performance warranty and a product warranty.

The product warranty is probably the more important one as it covers manufacturing defects and most problems experienced with solar panels. The new series of REC Alpha Solar offers 25 years for their product warranty on their panels that are sold in Australia which is just about as good as it gets for residential solar panels. While the other series of REC panels offer a 20 year product warranty with a 25 year performance warranty, which can be extended to 25 years if the installer is a ‘REC accredited installer’.

The performance warranty of REC solar panels is also industry leading. The Alpha and N-peak 2 series offer a guarantee that the solar panels won’t degrade more than 2% in the first year and 0.25% per year thereafter for another 24 years. That means they will be performing to at least 92% of their nameplate value after 25 years. The twin-peak 2 series has a slightly lower guarantee of 0.5% per year for years 2-25 landing at 86% of the nameplate value after 25 years.

REC have a very clearly documented process to claim a warranty directly if your solar installer is no longer around to help you. 

Unlike most solar panel warranties REC will also cover the labour required during a warranty claim process if the solar panel is installed by an ‘accredited REC solar installer’.

REC Panel Technologies

Half-cut cells are the innovation that REC is best known for. The split module design allows for a more efficient solar panel than the standard cell design, providing a number of advantages. Many other manufacturers are developing their own half-cut cell panels. The REC Group has opened a patent infringement lawsuit against Hanwha Q Cells in China, over the half-cut cell technology.

We are awaiting the launch of the Alpha 72 which was scheduled to start production in May 2020. The Alpha 72 tested up to 450Wp at 21.3% efficiency, this combination of high performance and quality will enable REC to further capitalise in the market.

REC Alpha Series

REC Alpha Solar Panel

The Alpha Series is the most recent panel to be developed by REC, unveiled in early 2019. With capacity up to 380W, the solar panel is composed of 120 half-cut heterojunction cells. With N-Type silcon, the module has a slower degradation rate and a better temperature coefficient compared to solar panels using P-Type silicon. With a high-power density of 217.14 W/m², the REC Alpha 380W has a 26% greater annual energy yield compared to a typical 320W panel. The REC Alpha is solder-free which increases panel longevity, by removing the risk of potential cell damage from cracking. This feature also improves their sustainability, as the solder-free cell design reduces the lead content by 81%. The REC Alpha award-winning Twin panel design splits the panel into two twin sections, as pictured. This enables greater energy production in shaded conditions, getting the most out of the sun at all times. REC claims that after 25 years it will still have at least 92% of its initial power, which is an industry leading degradation rate.

REC N-Peak Black SeriesREC N-Peak Black Series

The REC N-Peak Black Series solar panels utilise black monocrystalline half-cut cell technology constructed with N-Type silicon. The sleek and seamless all black panel was designed to provide an aesthetic option for residential roofs. The panel was the first solar panel to combine N-Type monocrystalline half-cut cells with a twin-panel design. The 305 to 325W panel has 120 half-cut cells, structured in 6 strings of 20 cells. The REC N-Peak Black Series has extra support bars, enabling the panel to hold loads 30% heavier than conventional panels. This results in a higher energy yield per square metre making it an attractive option where roof space is at a premium.

REC TwinPeak 2 Mono SeriesREC TwinPeak 2 Mono Series Solar Panel

The REC TwinPeak 2 Mono Series is comprised of P-Type monocrystalline PERC cells, offering heightened efficiency accredited with REC’s industry leading half-cut cell technology. The efficient panel gets the most out of whatever space available. Not surprisingly, the TwinPeak 2 Mono panel is constructed as REC’s unique twin split panel design. This enables as previously mentioned, the benefit of electricity generation even when panels are partially shaded from the sun.
