Seems like efficiency will be ruined with rain

when is this expected in the Market?

237.5 watts per sq meter. Cool.

Durability?

In that this requires less doping elements, will this be less expensive than traditional monocrystalline panels? What about longevity? Also, on over cast days, where the light is diffused, how much less power will these produce, where the light can't be focused? is it going to have the same problems as thermal concentrated solar? Standard monocrystalline panels can maintain up to half their rated power on an overcast day, with a good maximum power point tracking control, or DC optimizer. The higher efficiency might make up for the reduced capacity factor in some areas.

good job! looking forward to seeing better producing solar panels

Raw.Lemon solar sphere does almost the same 🙂

Useful technology.

It would be very wise to have the water cooler tube behind the solar panel. The lenses heat up the panels and the water. We can use the heated water later on for the shower. Could be perfect as a mix of solar panel + water heater.

How much will they be sold compared to the standard ones? We already have this technology in space and it reaches over 40% efficiency

How you guys deal with condensation under lenses? Standard panels are fused together with PVB to ensure zero moisture on cells. Other than that looks like a great fit for dens urban environment.

Sorry to be a negative-nancy, however a MAJOR problem: solar efficiency depends on good cooling. A concentrator-lens creates a "greenhouse" over the semiconductor, making it difficult to cool effectively. This was amply demonstrated during the solar-challenge in Australia. How do you propose to cool the chips?

CPV. You just described a Concentrator PhotoVoltaic system. How is this is any way novel?

It's like nature. No new material has to be invented, but the biggest differences between species is geometry.
