Combining The 5 Best Solar Technologies

Monday, October 27th, 2008

I know there is a lot of red tape and patents that would make this impossible in the near future, but what if we could combine the 5 most effective solar technologies in the world and create a super solar collector that would be able to take care of our energy needs? I know it kinda sounds like Captain Planet, but I don’t think its too far out of reach. A few criteria have been taken into consideration. The super solar cell must be efficient, drive the cost down, and solve the problem of solar power at night. I know its a long shot, but here are my five picks.

1. In terms of the shape of the cell, I think Solyndra has it right in making cylindrical solar cells. They don’t have to be mounted at an angle. They can be mounted flat which saves installation costs and makes them more durable read more »

Solar Tubes More Efficient

It would seem counter intuitive that cylinder shaped solar panels would be more efficient and cost effective than flat. After all, anything with a curve is usually more expensive to make, and the loss of perpendicular surface area to the sun should make these solar tubes less efficient…right?

Well according to Solyndra, the company who makes these cylindrical solar cells, many factors are not taken into consideration. “With a cylinder, we are collecting light from all angles, even collecting diffuse light,” says CEO Chris Gronet, who founded the solar cylinder company in 2005 based on an idea he had late one night while pondering less expensive ways to install photovoltaic panels. Because the arrays do not have to be angled or anchored into the roof, he adds, “we have half the installation cost and can install in one third the time.”

These cells essentially look like dark flourescent light bulbs and have many advantages over their flat counterparts.

Solyndra is now churning out copper-indium-gallium-selenide (CIGS) thin-film solar cells, wrapped into a cylindrical shape and encased in glass. This design not only seals out moisture but allows the glass to act as a sunlight concentrator, funneling photons onto the thin film, read more »
