The US welcomes a new player in the solar game: Sunmac Solar. What do we know about this newcomer and are their panels worth your investment? Let’s find it out in our Sunmac Solar panels review.
There is little information about Sunmac Solar. Beyond a vague claim of selling “high efficiency PERC PV modules at an extremely competitive price”, there’s nothing on their website. Sunmac Solar was founded in 2022, according to their LinkedIn profile. The datasheets say the company is based in Irvine, California. The panels are not made in the US though: Sunmac Solar acknowledges they import their modules from their partners in Cambodia.
There aren’t many details about their Asian suppliers, except the fact that their manufacturing capacity amounts to 2GW annually. For the high-volume Asian solar panel market, these are rookie numbers. Leading names like Jinko Solar operate at a staggering 100GW annually.
19.5%–21.5%
efficiency
Sunmac solar panels deliver between 355 and 555 watts of power. A bit small for commercial installations, but enough for home solar systems. When it comes to efficiency, Sunmac solar panels boast efficiencies ranging from 19.5% to 21.5%, not great, but still competitive within the industry.
25-year
product and performance warranty
Sunmac offers a 25-year warranty covering both product and performance. The product warranty covers defects in materials and workmanship, while the power output warranty guarantees 84.8% of the original output after 25 years of operation. Bear in mind that Sunmac was founded only in 2022 and it’s a small company. The statistics show that 50% of businesses in the US go bankrupt in the first 5 years of operation. If things go bad for the company, no one will give your money back.
$0.6–$0.8
price per watt
Pricing seems to be a significant advantage of Sunmac solar panels, starting at about $0.6–$0.8 per watt. But it’s only at first sight. The market offers panels with way better characteristics from more recognized brands for about the same price.
It’s time to break down the bright and dark sides of Sunmac solar panels. What we like about their panels:
✓ Nice residential option: Sunmac offers not bad modules for home solar systems. Average specifications at an average price. Nothing extra.
Still, there are clear disadvantages of Sunmac Solar panels that we have to point out. Here’s what we don’t like about Sunmac:
✗ Wasteland of information: Sunmac’s website offers little to no information on their experience in the solar industry. The lack of transparency surrounding Sunmac makes it difficult to assess the quality of their modules. Without details on the manufacturing process and materials used, it’s hard to suggest how well Sunmac panels will perform over time.
✗ Scarcity of customer reviews: There seem to be very few, if any, real online reviews from homeowners who have installed Sunmac panels. This makes it difficult to gauge real-world performance, satisfaction, and potential issues. This reinforces the concerns about the brand’s overall transparency and potentially adds another layer of risk to choosing them.
Time to move from specifications to the real panels. Let’s see if the actual panels can change our minds.
The M754SH-BB series solar panels are ideal for smaller installations. They deliver dependable output of 390W-410W with good efficiency of 20%-21%. These panels are backed by a 25-year product and performance warranty, making it a nice choice for home solar systems.
The M672NH-WB series solar panels are perfect for residential solar setups. They generate solid 430-455 watts of power with nice efficiency of 20%-21%. These panels come with an industry-standard 25-year warranty on both product and performance. It’s a budget-friendly and reliable option for homeowners switching to solar.
The M772SH-TB series bifacial panels are top performers for ambitious solar projects. They boast an impressive output of 530W-555W and high efficiency of 20.5%-21.5%, maximizing energy generation even in limited space. Like other modules, they come with a 25-year product and performance warranty. These panels are ideal for those seeking maximum power production.

If what we’ve learned about Sumac Solar so far is correct, then Sunmac Solar is a small and very young company. Early years in the business are tough and it’s understandable that the company hasn’t got around yet to keep their customers informed about who they are, what they do and how they do it.
Still, the lack of transparency regarding their manufacturing partners and production facilities raises concerns about quality control and potential risks. Hopefully, they’ll do well on the market, tell the world about it and maybe then this review will get a positive update. With that, we end our Sunmac Solar panels review.
