With so many different companies producing solar cells and solar arrays, it’s a pretty competitive field. Toshiba’s 22.6% conversion efficiency ranks near the top – in the lab. Toshiba has stated its results in the field, so to speak, are at 19.3% conversion efficiency, putting its Residential Solar Module 240W right at the top.
Toshiba’s set-up uses American SunPower solar cells, with a rear contact monocrystalline system. To reduce the loss of reflected light, it uses coated glass, which increases the active area by approximately 3% for a 240W maximum output.
Because more power is generated over the same surface area, Toshiba’s customers can either opt for a smaller array with the same power output or use the same surface area as their competitors to gather a stated 40% power increase over the course of a year. Using the excess energy buyback program, energy costs can go way down.
My question is, when will they start sticking solar panels onto their nifty laptops?
