solar tiles

Researchers built the device by attaching 17%-efficient monocrystalline PV cells to a mortar roof tile that was doped with a phase-change material (PCM). The PCM solar tile provided 4.1% more power than the PV tile with no cooling agent in the winter, and 2.2% to 4.3% more during the summer.

U.K. business Roof Tiles Technology Ltd has developed a solar tile with a claimed efficiency of 17.5% and power output of 175 W per square meter. The company’s founder, Antonio Lanzoni, said a PV system featuring the product would cost 25-30% more than a standard solar rooftop.

The internet’s favorite energy company installed 530 megawatt-hours of battery storage in Q4, beating out the previous record, set last quarter, as well as showing continued improvement in solar installations.

State energy minister Nilesh Cabral says householders will be offered the chance to reduce energy bills without any upfront cost by leasing roofspace to installers as part of plans to add 15 MW of solar capacity in Goa by March.
