How the new generation of 500 watt panels will shape the solar industry
With three fashions of 500-watt solar panels https://www.solartex.co/ formally unveiled, right here’s a observe what that means for the future of challenge improvement and the sun industry at huge.

There are two solar module manufacturers, Risen Energy and Trina Solar, that have unveiled first-of-their type 500W, 50-mobile, PV modules.
The Risen modules accomplish the feat the usage of 50 1/2-cut monocrystalline PERC cells, witch each character mobile being 210 mm in length., The Trina panels use the came 210 mm silicon wafers, with the distinction among the two businesses being that Trina’s are tri-cut. What this effects in is a 500W module that comes in just slightly larger than 72-mobile designs with 156.Seventy five mm wafers.
How will the advent of 500-watt solar modules alternate the sun industry?
“For packages in which you’ve got a number of vicinity, mainly industrial and in particular utility-scale, it’s genuinely significant,” CEO of Cinnamon Energy Systems Barry Cinnamon advised pv mag. “You may want to simply use fewer modules, it reduces dealing with prices and typical balance-of-gadget charges move down.”
If there are less modules needed to attain the potential specs of a task, meaning usual undertaking prices will move down as those modules emerge as economically possible. A large area with a purpose to see price reduction will come from the racking and trackers.
“It’s going to power down the fee of racks and trackers in line with watt,” stated Matt Kesler, head of era at OMCO Solar, an Arizona-primarily based racking and fixed tilt tracking manufacturer. “It’ll reduce the cost in line with watt of set up labor. It’s also going to give a top rate on racks and trackers which are designed for ergonomics. As these items get bigger they’re going to get heavier and wider. If there are capabilities inside the trackers and racks that help inside the placement of the modules, that’s going to have extra fee.”
The consensus the various installers interviewed by way of pv magazine was that the common module established checks in at 380W. This manner that Trina and Risen’s panels deliver round 31% more strength than the common established panel. Cinnamon stated that 10 years in the past, the common module output changed into approximately 250W.
As neat as that calculation is, these panels have a long way to head until they are enterprise requirements, let alone the benchmark for the common set up.
“It takes about 5 years for the enterprise to change all of its assembly equipment to a new size,” said Cinnamon “It’s quite a few paintings to shop for new device due to the fact often it is able to’t be reprogrammed… We’re talking three to five years to exchange out all of that device.”
“The maximum not unusual area is going to be C&I,” said Jock Patterson of Fronius USA, an inverter business enterprise. “I see those on rooftops wherein area is limited and they need better performance modules. Large suppliers are going to feel the stress to deliver an inverter that’s 1,500 volts. Those who aren’t providing which are going to sense like they’re lacking out on the ones larger rooftop initiatives.”
That exchange will now not be enterprise-wide. The residential solar market will see little direct impact as these modules turn out to be commercially to be had — as seventy two-mobile modules have constantly been too huge to be practical for domestic installations wherein roof area is confined, work spaces are angled and employees have with a view to convey the modules in my opinion up ladders. Anything beyond the standard 1-meter by 1.6-meter 60-cell module is too bulky.
The wish for the residential installers that pv mag spoke with turned into that the technologies used to get these modules to 500W will eventually tickle all the way down to their 60-cellular brethren. In flip, this would mean that residential installations would be able to take up much less roof place even as supplying extra strength, in the long run driving down stability-of-system costs.
Risen claims that it may without problems attain 600Wp of output with a 60-mobile panel, however the length might make the panel too huge to be dealt with by means of a unmarried individual.
Edit: This article was edited on three/nine/20 mirror that the modules are 50-mobile, now not seventy two-mobile, as was initially reported. We express regret for the error.

The PV module within the photograph does no longer appear to have 72 cells, but rather a hundred cells in a five x 20 layout. Also, there is a deceptive remark about 1500V inverters and rooftops, while we all know that 1500V systems can’t be located on rooftops, in step with the National Electrical Code. Further, it does not seem that performance improvements have led to this boom in electricity, however additional cells.

Ditto- this guy’s on it

Came right here to say the identical thing. This is a totally deceptive article. This isn’t a 72 cell mod, however what looks to be a hundred, 1/2 mobile, huge format cells (perhaps 144 tallmax?), multi bussbar module. If these are just like the rest of the tallmax line they is probably bifacial to get to the ones big numbers . These are still simplest inside the low 20’s for performance. This is notable, but for all of those humans commenting approximately becoming twice the sun inside the equal region, thats no longer what is occurring here… although the thing leads you to agree with that. At the quit of the day this is a module that squeezes most modern technology and “tricks” into a unmarried big module. On a C&I mission I consider it is able to keep round ~3% because of fewer modules (fewer clamps, much less wiring and many others), however no longer due to some magic high performance. As you stated 1500V isn’t always allowed on homes within the US. All I recognise is at eighty″x40″ @ 60lbs I am in no big hurry to lug those round or work the engineering.

My name is Mihai Iancu ,I study you article and I will kindly ask in your advocate concerning what form of photovoltaic panel I can buy for one studio ,that must cover 2 AC ,1 Tv,1 fridge.Thank you and accurate success!

More output on solar panels approach much less of a foot print. That is extremely treasured to some.
Not all systems can be roof mount. Houses in maximum cities simply aren’t that huge of a roof vicinity.

The maximum applicable variety for residential rooftop placement is the conversion efficiency, power per unit place.
Is 500w from 1 x 1.6 meters probable going to be possible? Woupdnt that be about 30% efficiency?

In the US commercial rooftops are restricted to 1000V max through NEC 690.7 “PV gadget dc circuits on or in buildings will be accredited to have a maximum voltage no greater than one thousand volts.”. Only ground mount may also use 1500V.

Wondering what this may do the re-electricity marketplace. Fields of sun panels that have been put up 10 years in the past ought to double or more their output – assuming the transmission potential is there.
I haven’t watched residential sun installers, but I could have assumed that at the least a number of them could are becoming the ladder hoist systems by now. One of my neighbors had his roof changed years in the past and the group used one to get the shingles up.
I would really like it if there was a 600W, 60-cellular panel. Even 500W would be gr
