By changing the way that conventional silicon solar panels are made, Day4 Energy, a startup based in Burnaby, British Columbia, has found a way to cut the cost of solar power by 25 percent, says George Rubin, the company's president.

What's this?

Who's leading the conversation?

This visualization below allows you to see the impact that each user has on the current conversation. The top row contains the group of users who have had the most impact, the 2nd row the group of users who have had the 2nd most impact (et cetera). Users with similar impact are grouped together, and the average score of the group is shown to the left of the group. The author of the article is also shown on the left, in their corresponding group. Each user's score is based on the number of comments the user has made plus the number of votes their comments have received. The scores are calculated relative one another, so while their absolute value is not particularly important, their relative difference does indicate a larger difference in impact on the conversation.

Great to see continuing technological innovation in solar panels:

The company has developed a new electrode that, together with a redesigned solar-cell structure, allows solar panels to absorb more light and operate at a higher voltage. This increases the efficiency of multicrystalline silicon solar panels from an industry standard of about 14 percent to nearly 17 percent. Because of this higher efficiency, Day4's solar panels generate more power than conventional panels do, yet they will cost the same, Rubin says. He estimates the cost per watt of solar power would be about $3, compared with $4 for conventional solar cells. That will translate into electricity prices of about 20 cents per kilowatt-hour in sunny areas, down from about 25 cents per kilowatt-hour, he says.

Other improvements are in the pipeline, so it's hard to know when to jump in.
