Re: [RE-wrenches] Isofoton modules

just last November I installed ~3 kW of Isofoton 150/24s that had been on a
pallet in the back of the shop for several years. After asking around I
found that other Texas installers had only put up a few arrays before the
Spanish based company pulled out of the US market altogether. SolarBuzz
doesn't even list them, at least under that name.
Being a standard 62x31 with 125mm cells should not be difficult to
duplicate in appearance. But I suspect that you're out of luck finding more
of the Isofoton brand.
They promote the microstructured glass design, an idea I was skeptical about
at first. However the low-light improvement they claim for the fine textured
glass fronts seems to be real. Overcast days production seems noticeably
higher than I'd expected.
I'm just glad that we still have 2 new spares.

We did a 6 kW system 6 years ago using 160 watt, 160 watt modules, and the
client recently called back and asked us to add another 4 kW.

We no longer install this brand of module and have lost track who in US
supplies them.  We found them to be well made and look great, but we just
started using other brands and slowly moved in other directions.

Their web page indicates they have or are building a plant in US, so I
assume they are still around, but do not know who is stocking these.  We
need the 160 watt size to best match the modules already installed, but
looks like they have re-worked these to now be 24 volt modules and our
original ones were 12 volt (17 Voc), but we can work around that.

Any idea?

Thanks,

Jeff Yago
