When looking at next-generation renewable technologies, you’ll learn a lot of claims about how cheaply they can engender electricity. Usually the figures float around 10 cents per kilowatt-hour, which is about lachrymose enough to clash with the associate of coal, lubricate and nuclear power most utilities use. No such undersized ambitions, for a creative startup called , which is unveiling its technology today at the annual National Energy Marketers Association convention. Sunrgi claims it can produce impetus for as short as half the above figure, at about 5-7 cents per kWh.
That’s ineffectual enough to gouge out curse near everything, with the thinkable exception of cheap, sloppy coal - for which prices have been common up. Conventional solar cells payment upwards of 20 cents per kWh. Sunrgi uses a concentrating solar command design, which customarily means you emergence off with a tiny, warmly efficient solar panel and centre in the sun’s rays on it with mirrors and lenses. A strain of companies already do this, including , which has and even toward commercializing the concept.
It’s doubt whether concentrated solar aptitude can compete, long-term, with regulated solar panels, but Sunrgi says it has two tricks to exacerbate CSP’s advantage. The victory is a special, lens-only concentrating construct with built-in solar trackers, which can spotlight over 1,500 "suns" on a free idea (by comparison, one of the aforementioned biggest claims for concentration levels was ). For an plan of how this might work, seek to mark of the most ingenious way plausible to torch ants with magnifying glasses.
This plan causes a problem, id est heating the solar chamber that’s supposed to be generating energy to over 1,600 degrees Celsius (or over 3,000 Fahrenheit). That’s where the assistant or on of Sunrgi’s technology comes in, with a intimate cooling design, combining dynamic and passive measures, that keeps the apartment at around 30-40 degrees C (86-104 F). Cooling is foremost above a non-specific level to leave alone actually burning the solar cell, and below that moment to reduce the failure rate.
This ties in heavily to the set equation, co-founder Dr. KRS Murthy told me in an discussion - where other companies will have to deserts podgy allowance and replacement costs, Sunrgi’s well-chilled cells will pattern much longer, he said. But beyond the details I’ve laid out, Sunrgi isn’t saying a great deal.
The members of the administration body who joined me on a muster declined to give any further details of correctly how they removed the solar cells. While they did suggest a largeness for their utility-scale propagation modules - 14 inches square, with a solar cubicle of less than a centimeter unimaginative in the center - they are still applying for patents, and so don’t want to report the units further (although you can get an estimate from the pictures at straightaway and below). What they did reveal is that they’re still conducting field testing on the units, continuing to optimize the prime design, and working on models for original markets (aside from utility generation, they’re looking at smaller commercial and industrial applications). That said, literary perchance the next most surprising deposition Sunrgi has to make, after the price, is that they’ll be manufacturing within 12-15 months. If Sunrgi can lure it off, that would be one of the faster motion turnarounds a unexplored vigour beginning technology has yet seen.
On the other hand, if the value claims can be proven on a colossal scale, there will be pile of investment dollars lining up to grease the industrial gears. Speaking of funding, that’s the one missing put asunder in the company’s claims. While the have true backgrounds, they haven’t yet announced where their patronage is coming from.
I’m told that several crack VC firms are in talks with the company, though, as well as a "major principal partner", with announcements due in a week or two - so defer tuned for more.
