MIT Students Create Solar Panels That Still Work In The Shade

Your shady roof is solar-power friendly now.

The number of homes with solar panels has grown quickly in the last few years. But there could be a lot more. Up to three-quarters of houses are still thought to be unsuitable for solar because of shading, ownership, and structural issues. Shading is also a serious issue even for homes with solar. Covering up just 3% of an array leads to a loss of 25% of power, according one estimate.

That’s why an invention by graduate students at MIT is potentially significant. It could both raise the performance of shaded panels and put homes that are currently excluded from solar into play. . . .
