LHow will the new generation of 500 watt panels shape the solar industry?
With three models of 500-watt solar panels officially unveiled, here’s a look at what that means for the future of project development and the solar industry at large.

There are two solar module manufacturers, Risen Energy and Trina Solar, that have unveiled first-of-their kind 500W, 72-cell PV modules.
How will the advent of 500-watt solar modules change the solar industry?
“For applications where you have a lot of area, particularly commercial and especially utility-scale, it’s really significant,” CEO of Cinnamon Energy Systems Barry Cinnamon told pv magazine. “You could just use fewer modules, it reduces handling costs and overall balance-of-system costs go down.”
If there are less modules needed to reach the capacity specifications of a project, that means overall project costs will go down as these modules become economically viable. A significant area that will see cost reduction will come from the racking and trackers.
“It’s going to drive down the cost of racks and trackers per module,” said Matt Kesler, head of technology at OMCO Solar, an Arizona-based racking and fixed tilt tracking manufacturer. “It’ll reduce the cost per watt of installation labor. It’s also going to give a premium on racks and trackers that are designed for ergonomics. As these things get bigger they’re going to get heavier and wider. if there are features in the trackers and racks that assist in the placement of the modules, that’s going to have more value.”
The consensus among the installers interviewed by pv magazine was that the average module installed checks in at 380W. This means that Trina and Risen’s panels deliver around 31% more power than the average installed panel. Cinnamon said that 10 years ago, the average module output was about 250W.
As neat as that calculation is, these panels have a long way to go until they are industry standards, let alone the benchmark for the average installation.
“It takes about five years for the industry to change all of its assembly equipment to a new size,” said Cinnamon “It’s a lot of work to buy new equipment because often it can’t be reprogrammed… We’re talking three to five years to change out all of that equipment.”
“The most common sector is going to be C&I,” said Jock Patterson of Fronius USA, an inverter company. “I see these on rooftops where space is limited and they want higher efficiency modules. Large suppliers are going to feel the pressure to supply an inverter that’s 1,500 volts. Those who aren’t providing that are going to feel like they’re missing out on those larger rooftop projects.”
That change will not be industry-wide. The residential solar market will see little direct impact as these modules become commercially available — as 72-cell modules have always been too large to be practical for home installations where roof space is limited, work spaces are angled and workers have to be able to carry the modules individually up ladders. Anything beyond the standard 1-meter by 1.6-meter 60-cell module is too cumbersome.
The hope for the residential installers that pv magazine spoke with was that the technologies used to get these modules to 500W will eventually tickle down to their 60-cell brethren. In turn, this would mean that residential installations would be able to take up less roof area while providing more power, ultimately driving down balance-of-system costs.
Risen claims that it could easily reach 600Wp of output with a 60-cell panel.

The PV module in the photo does not appear to have 72 cells, but rather 100 cells in a 5 x 20 layout. Also, there is a misleading comment about 1500V inverters and rooftops, when we all know that 1500V systems cannot be placed on rooftops, per the National Electrical Code. Further, it does not seem that efficiency improvements have led to this increase in power, but additional cells.

More output on solar panels means less of a foot print. That is extremely valuable to some.
Not all systems will be roof mount. Houses in most cities just aren’t that large of a roof area.

In the US commercial rooftops are limited to 1000V max by NEC 690.7 “PV system dc circuits on or in buildings shall be permitted to have a maximum voltage no greater than 1000 volts.”. Only ground mount may use 1500V.

Wondering what this will do the re-power market. Fields of solar panels that were put up 10 years ago could double or more their output – assuming the transmission capacity is there.
I haven’t watched residential solar installers, but I would have assumed that at least some of them would have gotten the ladder hoist systems by now. One of my neighbors had his roof replaced two years ago and the crew used one to get the shingles up.
I would love it if there was a 600W, 60-cell panel. Even 500W would be great.
