Non-flexible sunpower hard panels not by sunpower

[zboss]

Does anyone make non-flexible solar panels made of sunpower cells, besides sunpower?

Apparently not with the same capabilities, hence the price differential.

Solara Ultra-S glass panels are made with SunPower cells. Two sizes, 120W & 140W. Great product.

SunPower will allow their cells to be used by other mfg's, up to 140W. Above that you have to get SunPower panels.

Planning to get some 140 or 160 watt panels soon. What is the advantage to these over say grape solar or Kyocera?

[azsailor12]

Better performance at low sun angles because the conductors are on the back side of the cells- no shading from them.

[OceanPlanet]

They also have more power per sq. Ft. due to the higher efficiency SunPower cells. Of course they cost more per watt, that's the trade off...

They are significantly cheaper than the same 140 watt flexible panels.
