Fact is, if you’ve found yourself researching the Risen RSM60 poly solar panel range, you are shopping at the cheaper end of the solar panel buyers spectrum. There’s no sugar coating this for you. As we all have a different budget, sometimes it’s better to go solar as opposed to doing nothing at all. That being said, will the Risen RSM60 poly solar panel do the job or is it likely to miss the mark entirely?
Make and model: Risen RSM60.
Variants: 260W/ 265W / 270W / 275W / 280W
Good: 12-yr product warranty.
Not so good: Outdated technology.
Polycrystalline solar panels in general certainly aren’t where solar panel technologies are heading into the future thanks to greater expectations of efficiencies. However, for many, polycrystalline solar panels still serve the purpose of greater affordability. When more efficient technologies are created the manufacturers must recoup the cost of R&D within the final product. The good news, the Risen RSM60 poly solar module has endured minimal manufacturer investment in this regard.
As such, with all solar panels, the 6 essential criteria of design, durability, efficiency, performance, guarantee and affordability must still be assessed.
It’s hard to get excited about a stock standard poly-crystalline solar panel design. It’s especially worse when as the number 1 key feature on the data sheet the manufacturer lists that they, not the solar panel, are a Bloomberg Tier-1 listed manufacturer. Ultimately shifting the focus away from the lacklustre solar panel design.
Looking for some positives, potentially 5 busbars is better than 4? Still rather hard to get excited about as innovation is shift toward more enhanced innovation. Surely there’s got to be a true standout design feature? A lot of industry leading statements (which are covered later), but none of which are actually industry leading. Minus more points for deception.
2.4A less than inspiring design, the Risen RSM60 poly solar panel accrued a Solar Review Module Assessment Criteria Design score of 2.4 out of 5.
The Risen RSM60 poly matches the requirements for IEC standard, however that’s about as good as it gets in the durability rankings. With no real standout durability features, the Risen RSM60 poly matches average expectations in order to achieve a pass mark. Crucial durability tests of both temperature cycling and damp heat tests were both unlisted or readily available for end-user observation. A notable concern.
Above: Temperature change test, scale to 600 cycles.
Above: Damp heat test, scale to 4000 hours.
2.4A below average durability rating, the Risen RSM60 poly solar panel accrued a Solar Review Module Assessment Criteria Durability score of 2.4 out of 5.
Major feature number 3 as stated on the Risen RS60M poly datasheet, “Industry Leading Lowest Thermal co-efficient of Power” The temperature co-efficient of the Risen RS60M poly is at -0.39%C which is good but definitely not industry leading. An industry leading temperature co-efficient would be similar to that of which is achieved by Sunpower -0.29%/C (lower the better). Overall Efficiency is very average by todays standard at a high of only 17.1%.
Above: Efficiency comparison on a scale of 25%.
3.3Considered good, the Risen RSM60 poly solar panel accrued a Solar Review Module Assessment Criteria Efficiency score of 3.3 out of 5.
Adopting the much preferred linear performance guarantee, the performance of the Risen RS60M poly solar panel shall degrade at no more than 3% in year-1 and 0.7% per annum thereafter for the remaining 24-years. Definitely not a standout linear guarantee, however, a linear guarantee none-the-less, and always better than a stepped performance guarantee.
Above: Manufacturer nominated performance comparison at year 25.
3.6A good performance rating, the Risen RSM60 poly solar panel accrued a Solar Review Module Assessment Criteria Performance score of 3.6 out of 5.
Potentially the reason why one would select the Risen RSM60 poly over a similar polycrystalline solar panels at a comparable price point. Considered above the baseline norm, a 12-year product guarantee is often better than 10-years.
Above: Manufacturer product guarantee comparison 1 to 30 years.
2.2Below par, the Risen RSM60 poly solar panel accrued a Solar Review Module Assessment Criteria Performance score of 2.2 out of 5.
One of the cheapest solar panels available it’s hard to decipher value when looking into affordability. The price point is one of the most affordable available. However, purchasing a solar panel option in the Risen RSM60 poly range is much like buying a Nokia mobile phone. It will do the job initially but present limited real value over time when alternative variations will consistently outperform.
As a gauge, Risen RSM60 poly solar panels are available online from:
USD 0.32 per watt | AUD 0.45 per watt | EURO 0.28
Excludes taxes, shipping and installation.

3.7Presenting relatively good value, the Risen RSM60 poly solar panel accrued a Solar Review Module Assessment Criteria Affordability score of 3.7 out of 5.
Although priced exceptionally well, there are statements made by the manufacturer which are incorrect and misleading, especially for an end-user. Therefore, one must ask themselves, exactly how much of the information can be trusted which is provided by Risen relating to the Risen RSM60 poly solar panel range? The Risen RSM60 poly solar panel is a basic solar panel with an unclear ability to live up to the task in testing real-world conditions. Seek and compare alternative options.
