With California set to alpha doling out incentives for solar baptize heating systems on backdrop soon, you can apprehend to see added new companies bottleneck in this space. Startup Cogenra Solar is one of such new comer, and it has advised a amalgam arrangement that uses mirrors and solar beef to accomplish electricity and advantageous heat.
The system, which comes with a single-axis tracker, relies on bottle mirrors to apply the sunlight assimilate silicon solar beef to aftermath electricity, Cogenra CEO and founder, Gilad Almogy, told us in a contempo interview. And in the aforementioned arena area the beef abide is a fluid-containing tube that absorbs the calefaction produced from the action of electricity production.
The fluid, a glycol admixture that is freeze-resistant and frequently acclimated to alteration calefaction in cars and liquid-cooled computers, is again piped to a captivation catchbasin for heating baptize (see diagram below). In settings that requires hot baptize about the clock, a boiler charcoal all-important for the final heating.
“It’s a arrangement optimized for both awful able PV and calefaction generation,” said Almogy, who founded the aggregation (previously alleged SkyWatch Energy) aftermost year, has aloft $10.5 actor and counts Khosla Ventures as amid its investors.
A console abounding with silicon solar beef about can catechumen about 16 percent of the sunlight that avalanche on it into electricity. The blow of the solar activity becomes heat, which is blown but can abuse the achievement of solar cells. A growing cardinal of companies, like PVT Solar, Cool Activity and Conserval Engineering, are attractive at means to accomplish electricity while additionally authoritative use of the heat. Cogenra’s arrangement can about-face 75 percent of the solar activity into advantageous electricity and heat, Almogy said.
Almogy said the arrangement can punch up and bottomward the adapted temperatures of the water, from about 120-degree F for businesses such as hotels to about 180-degree F for automated operations such as aliment processing.
Almogy’s aboriginal advertise accession will be a 272-kilowatt arrangement at the Sonoma Wine Aggregation in Graton, a boondocks in Northern California, the aggregation said Wednesday. The admeasurement of the accession is beyond than the 80-kilowatt one that Cogenra had initially estimated back it activated for a admission from the California Public Utilities Commission, which has accustomed $1.47 actor for the aggregation to advance new appearance for its amalgam designs.
Cogenra affairs to analyze means to automate the arrangement so that it can, say, focus on breeding added electricity and beneath calefaction at altered times during the day back electricity ante and appeal are high, said Almogy. Cogenra and Sonoma Wine Aggregation will pony up $2.7 actor absolute for the activity and Cogenra affairs to about-face on the accession at the wine aggregation in November.
Sonoma Wine won’t own the system, however. Cogenra will own and accomplish the accession and advertise the electricity and thermal activity beneath a abiding agreement. Cogenra affairs to accomplish money from alms such calefaction and electricity sales agreements, as able-bodied as from affairs equipment. The aggregation can use its own money to abutment some antecedent activity contracts, but will charge to accession activity costs to sustain the business.
Cogenra’s actualization comes at a time back California is set to barrage an allurement affairs for solar baptize heating systems installed for businesses and multifamily housings. The California Solar Initiative-Thermal launched the residential allotment of the affairs in May this year, and could alpha the bartering and multifamily allocation by the end of this week.
The accompaniment has approaching $350.8 actor for the absolute CSI-Thermal affairs and affairs to run it until the end of 2017, or back the money is spent. Residential systems get a abatement based on the estimated bulk of thermal activity (in therms) or electricity (in kilowatt hours) that the systems can displace in the aboriginal year.
Commercial, and multifamily systems of up to 250-kilowatt would chase the aforementioned abatement scheme, according to proposed rules. For systems beyond than 250-kilowatt, the accompaniment will aboriginal pay 70 percent of the estimated displacement for the aboriginal year. The blow will depend on how abundant the systems absolutely accomplish afterwards one year.
