It would probably have been better to invest in new Hyper X 2 bifacial (double sided) ultra high efficiency, solar technology. This advanced technology has been around for the past 6 years but it was always considered to be far too expensive to install. Now because of new technological advances Hyper X 2 Bifacial solar panels can be purchased at a much lower cost than many standard single sided solar panels.
Instead of boxy looking 1 1/2 to 2 inch thick framed Gen 1 solar panels, these new higher performance Gen 2 solar panels are only 1/4 inch thin and are made with a stronger, see through, glass on glass, frameless, construction that allows sunlight to pass through and reflect off the roof's surface, thus illuminating the backside of the double sided solar cells, producing additional power.
A mere 10% boost in reflected light can raise this 340 watt solar panel's output to 374 watts without taking up anymore roof space. New Hyper X 2 solar offers a better PTC to STC ratio "Real World" performance according to the California Energy Commission's performance rating listings than over 100 of SunPower's solar panel models.
And they offer a very high 92.88% PTC to STC performance ratio. Hyper X 2 also offers a heat resistant -0.31%/degree C temperature coefficient for better performance in warm/hot climates. And when it comes to aesthetics, nothing even comes close to Hyper X 2's glass on glass, see through, frameless construction.
With N-type mono-crystalline bifacial cells for double sided power production, up to a 21.5% efficiency rating, superior aesthetics, and a price that outcompetes the solar lease and PPA company's offerings, very few products on the market compares to Hyper X 2 Solar. http://vimeo.com/111960877
