Overview of REC: Who is REC & What is their Position in Australia?
Originating from Norway, REC Group is now owned by Reliance Industries, and the company manufactures panels mainly in Singapore and Norway.
This award-winning solar company, with a Tier 1 title, was founded in 1996 and has grown to become a leading innovator in solar PV technology.
However, Australia is one of REC’s important markets. Several solar installers here regularly evaluate panel brands, and REC often ranks near the top in installer surveys, particularly for top-notch quality and first-rate after‑sales support.
The company employs over 2,000 people and operates an advanced manufacturing plant in Singapore.
Typically, REC produces approximately 1.5 GW of solar panels per year. REC is still growing, although it remains small in comparison to the massive Chinese solar manufacturers. The company is also a leader in sustainability within the industry.Â
The operations headquarters and manufacturing facilities are in Singapore. And the new parent company, Reliance New Energy Solar, is part of the Indian conglomerate Reliance Industries as of 2021.
The company has several offices worldwide, including one in Melbourne’s CBD. REC is a fully vertically integrated company. Therefore, they manufacture everything from silicon ingots and wafers to cells and complete module assemblies.
Since they make everything in-house, it gives them complete control over the quality and traceability of all components.
REC claims to have the industry’s lowest warranty rate. It is a big claim and difficult to verify. But given the overwhelmingly positive feedback, they are definitely known to produce highly reliable and high-performing panels.
Especially, they are known for their effectiveness in the harsh Australian climate, with very few known quality issues.
Also, the REC Certified Solar Professional Program allows them to offer their customers longer warranty periods, including a product and labour warranty of up to 25 years.
REC Solar Panels: Let’s Have a Glance!
REC is a pioneer in the solar industry and a leading innovator in solar PV technology. The advanced Alpha series panels use high-performance heterojunction cells.
These cells have taken REC to a new level, elevating it to the world’s best manufacturers. And they are still among the most efficient solar panels on the market.Â
In this highly competitive solar market, the more affordable REC Twinpeak and N-peak solar panels offer excellent value for money. They are backed by a 20-year product warranty and a 25-year performance warranty.
Undoubtedly, the range is longer than the average industry!
Let’s take a closer look at what makes REC a serious contender in the solar game in Australia:
- Panel details: Bloomberg Tier 1 Solar Panel
- Power rating (Watts): 360W – 450W
- Efficiency (%):5% to 22.3%
- Cell technology: N-type and Heterojunction
- Price range: Med to High
- Most popular panel: Alpha 400W
- Product Warranty: 20 years
- Service and support: 5/5
- Overall: Highly recommended
Revolutionary Cell Technology: More Power, Less Roof Space!
REC was the first company in the world to release panels that used the innovative split module design with half-cut cells.
The high-efficiency PERC cell architecture is also used by REC in the entire TwinPeak panel line. Because of the many advantages and improved efficiency of the half-cell design, it is now becoming an industry standard.Â
Innovative Half-cut Cells
The half-cut cell and split module design effectively divides the solar panel into two halves, each with 60 ‘half-size’ cells, for a total of 120 cells.
The two halves are joined parallel at the center of the panel but operate independently. So, if one half is shaded, the performance of the other half of the panel is not affected.
When a small portion of a full-size 60-cell panel is shaded, it can lose up to 40% of its power. Another advantage of the half-cut cell format is that the current is reduced to half per side.
Ultimately, it reduces resistance and losses by 75% of hot spot formation from shaded cells. Overall, the half-cut cell and split panel design increases panel performance.
High-performance N-type Silicon Cells
The introduction of the N-Peak series in 2018 amplifies REC’s position as a pioneer in half-cut cell technology.
REC was the first manufacturer to create half-cut cells out of high-performance N-type silicon rather than the more common, lower-cost P-type mono or multi-silicon wafers.
This places REC in the same league as Jinko, Panasonic, and SunPower, which are among the few other manufacturers that use high-purity N-type silicon wafers.
REC has included PERT, or ‘passivated emitter rear totally diffused’ cell technology, in addition to N-type silicon. The PERT process increases cell efficiency by utilizing full passivation on the cell’s backside to absorb more light photons and generate more energy.
Heterojunction HJT Cells
The REC Alpha series was the first mass-produced solar panel to use heterojunction (HJT) in a half-cut cell format.
To increase cell efficiency, the HJT cells are built on a high-purity N-type silicon base with a thin-film layer of amorphous silicon above and below the cell.
The HJT cells also have 16 microwire busbars, which increase efficiency and provide exceptional high-temperature performance with a very low-temperature coefficient of 0.26%, which is significantly lower than the industry standard of 0.38%.

Efficiency
The term solar panel efficiency refers to how effectively a solar panel captures and converts sunlight into usable electricity.
A high-efficiency solar panel will produce more electricity than a lower-efficiency panel of the same size under the same conditions. As a result, a higher energy efficiency rating is generally preferred.
The efficiency of your REC solar panels will differ depending on the model you select for your system. Solar panels in REC’s product line have efficiency ratings ranging from 19.1% to 22.3%.Â
Cost & Warranty
We already know REC solar panels are a top choice in Australia for their performance and reliability, but prices can vary depending on the model, system size, and your location.
Here’s a quick breakdown:
- REC Alpha Series: These premium panels typically cost between $300 and $500 each, offering cutting-edge efficiency for homeowners who want top-tier tech.
- REC TwinPeak Series: A more budget-friendly option, these panels usually range from $250 to $350 each and are great for those looking to balance performance with affordability.
When it comes to complete systems, most solar installers bundle everything together: panels, inverters, professional installation, and other setup fees.
- 6kW Solar System, ideal for average households, this setup generally costs between $5,000 and $8,500 fully installed.
- For a 10kW Solar System for larger families or small businesses, expect to pay around $9,500 to $15,000, depending on your specific needs and location.
However, the final pricing will always depend on a Certified Installer’s quote and other available solar rebates, so it’s best to research and get a few estimates.
Warranty
- Alpha Series: 25-year product warranty with 92% power output retained after 25 years.
- TwinPeak & N-Peak Series: 20-year product warranty (extendable to 25 years with certified REC installers) and 86% retained output after 25 years.
REC also offers reliable global support, with service offices across the U.S., Europe, and Asia, ensuring peace of mind for homeowners.
What to Consider If You’re Choosing REC for Your Aussie Homes?
If you’re weighing REC against other alternatives, here are some tips to follow:
- Ensure the installer is REC Certified to unlock the ProTrust warranty on labour, performance, and product.
- Check local environmental stressors such as coastal salt, heat, and hail. Match panel specs according to your situation.
- Compare the efficiency & panel size of your property. If roof space is limited or expensive, REC’s higher percentages per m² are useful.
- Don’t assume upfront cost is everything; calculate the lifetime cost per kWh. A more efficient, longer‑lasting panel may cost more upfront but pay off more over 20‑25 years.
- Check where the panel is made and if local support is available. Also, look at independent reviews and test ratings for the best panels.
What to Consider If You’re Choosing REC for Your Aussie Homes?
With over ten years in the industry, we confidently can say that REC can be an excellent choice to power your homes even in an off-grid setup. Reason?
Depending on the market criteria and the company’s reputation, their warranty and solar panel range are better than satisfactory. According to many customers, they are even better than most other renowned solar companies.
Therefore, you can choose REC Solar any day. However, the final decision remains up to you.
