Mitrex Integrated Solar Technology, a Canadian building-integrated PV module producer, has released a new 790 W panel with a power conversion efficiency of 19.5%.
The Mega HP M790-M1F module is the company's most powerful product. It combines two 395 W panels fused in a single device. It is built with 144 monocrystalline cells with an efficiency of 22.5%, 3.2 mm tempered glass, and an IP68 enclosure.
The panel measures 2,036 mm x 1,992 mm x 40 mm and weighs in at 42 kg. It can operate with a system voltage of 1,000 V and has a power temperature coefficient of -0.36% per degree Celsius. The open-circuit voltage is 96.2 V and the short-circuit current is 9.86 A.
“During the first year, Mitrex warrants the actual power output of the products will be no less than 97% of the labeled power output,” a company spokesperson told pv magazine. “From year two to year 25, the actual annual power decline will be no more than .7% by the end of year 25. By the end of year 25, the actual power output will be no less than 80% of the labeled power output.”
Mitrex produces the panels at its facility in Toronto. It said it is using its patented anti-reflecting technology, which involves color-treating the glass through pigments that are fused into the glass itself.
“The glass coating materials are characterized by high solar transmittance, minimal absorption, and increased durability,” the manufacturer said on its website, in reference to the colored layers. “Treated glass can have reflective, semi-reflective, or matte surfaces, depending on the product’s aesthetic requirements.”
Mitrex also makes smaller solar modules, as well as PV facades, solar cladding, solar glass and BIPV systems.

What’s the point? The watts/m2 are no different to a 395W panel. It’s just heavier for installers, more awkward to manoeuvre, harder to transport, more difficult to attach to racking, has less strength against weather. You could make a 1580W panel by sticking two of these together. Panel manufacturers need to make a standard size, no bigger than 2.1m x 1m and increase the efficiency to get more watts. That would be more valuable than bolting two panels together.
Great if one considers that the weight upon the roof is too much, heavy hail could cause cracks . To change the panel is easyer if there are smaller sizes.
4 square metres is one very big panel. I don’t see this being very useful apart from large solar farms and even there I do wonder if the handling logistics make it easier having a pair of 1m x 2m instead.
Mind you, 800w on a single panel makes good bragging rights 🙂
Are the panels placed horizontally or vertically or at angle (inclines)?
3 months later: Introducing our new 1185W solar panel. It has 216 cells and an open circuit voltage of 144.3V. The panel measures 3054mm x 1992mm x 40mm and weighs in at 63kg…
3 months after that: Introducing our new 1580W solar panel. It has 288 cells and an open circuit voltage of 192.4V. The panel measures 4072mm x 1992mm x 40mm and weighs in at 84kg…
I think these will let big projects install more watts per day, fewer pieces means fewer connections and parts. Outside of this maybe not practical for residential use.
After three years of having a 10 kW ground-based solar, we are disappointed.
We get paid only 6 cents per kWh when exporting to the grid.
But we have to pay 27 cents per kWh when taking from the grid for charging our EV overnight.
We are about to install a natural gas CHP to produce our own electricity at 4 – 6 cents per kWh and heat our hours at the same time.
What type of system and also no battery and type of generator does your array have the ability to start stop the generator and run automatically
Consider small space on roof. Motorhome, mobile home, houseboat, tiny home, etc., perhaps owner does not want whole roof covered or wants more out of the space they have.
There is a market for more energy. Spin back that electric meter faster.
I am still considering.
