Peimar SM325M solar panels review

Peimar is an Italian manufacturer specialising in the design, research and production of high-efficiency renewable products, including solar panels, inverters and storage batteries. It is known for its focus on quality and is a key player in the renewable energy sector.

While the SM325M offers an affordable cost of solar panel, its durability and performance fall short compared to the best solar panels. However, it remains a reasonable choice for budget-conscious homeowners.

Peimar monocrystalline solar panels are made using a combination of innovative production processes and engineering techniques to deliver maximum output and high performance. Homeowners need fewer panels to generate more energy, which can be useful for smaller roofs. Their long lifespan makes these solar panels a good choice for homeowners looking to recuperate costs and cut energy expenditures in the long term.

The Peimar SM325M is a popular solar panel with several benefits. 

• Modern design: Peimar SM325M solar panels have an attractive modern design, using matching black cells and panels to blend in with a dark roof. 
• Solid reputation: Peimar specialises in the design, research and manufacturing of solar panels. They hold a 4.56-star rating on Solar Reviews. 
• Cost: At around £143 per panel, Peimar is one of the most affordable solar panel brands on the market. 
• High wind resistance: With a 5400 Pa for wind loading, Peimar’s performance is nearly double the industry standard 2400 Pa wind rating.
• Lengthy guarantee: With a lengthy 30-year linear warranty, Peimar demonstrates confidence in its product.

There are always disadvantages that have to be taken into account, including:

• Performance: With an efficiency of only 19.48%, the Peimar SM325M is not the best performing solar panel on the market. 
• Output: While 325kW is a fair output, larger homes will benefit from brands offering 400kW outputs, like SunPower or LG. 
• Degradation: While panels will degrade 3% in the first year and then approximately 0.59% for every subsequent year, which is a much faster rate of degradation than many of its competitors, our best panels typically have an initial degradation rate of 1%.

Monocrystalline solar panels use cells made from a single pure crystal of silicon. Daylight excites the electrons in the silicon, stimulating them to flow and create an electric current. The panels then capture this electricity, which is used to power homes and devices. Monocrystalline panels efficiently convert sunlight into energy because the single-crystal structure allows for a smooth flow of electrons.

Peimar SM325M add-ons

Peimar is an affordable, entry-level solar panel. However, its output, efficiency and degradation fall short compared to many brands. Its 30-year linear warranty can be compared favourably with those of market leaders, such as Project Solar and Jinko.   

This table is an overview of how Peimar SM325M solar panels compare to others on the market.

Pricing for the JA Solar panel brand is similar to Peimar; however, it typically offers a linear warranty of 25 years and a product warranty of 12 years compared with Peimar’s 30-year linear and 20-year product warranties.

If you are looking for a solid product at a low price that can beat the performance of the Peimar SM325M, the Panasonic HIT N 245W is a good choice. This panel’s size makes it easy to adapt to smaller roofs or those with a complicated design, while its efficiency of 19.4% makes it comparable to the Peimar solar panel. Panasonic is still an affordable option at around £250 per panel (excluding installation and labour costs) and has a 25-year warranty.

Note that Panasonic no longer manufactures solar panels in house but still works with third-party manufacturers. The Panasonic HIT N 245W may still be available to buy from some providers, and the company will honour warranties.

Peimar PM325M solar panels are among the most affordable on the market, although there are some trade-offs in terms of quality. Here’s how it compares to others:

Peimar solar panels require little to no maintenance from homeowners. In fact, homeowners are discouraged from actively cleaning or tampering with the solar panels once they’ve been installed. 

If you do notice any issue with the performance of your solar panels, it’s best to contact Peimar directly to investigate. If you notice a build-up of dust or debris on the solar panel that is not washing off with regular rainfall, you can use a hose while on the ground to gently clean the solar panels.

Peimar panels are affordable and efficient. While they are not the most powerful on the market, there are a lot of advantages to choosing Peimar. They are cheaper than most, perform well, and come with attractive warranties. 

The sleek, slim, and all-black design makes them easy to live with in the long term, and while durability isn’t the best on the market, it’s far from the worst. Judging by the number of positive reviews written by customers on various sites, most homeowners are happy with their Peimar panels. 

In short, they provide a solid output and performance for space-restricted homes, homes with complex roofing designs, or homes located in areas where they face challenging weather conditions. They are also great for budget-conscious homeowners that want to purchase solar panels for their starter or retirement homes.
