A group of scientists at the University of Cordoba, in Spain, has developed a photovoltaic system design for hot water production that is claimed to use around 95% of the available energy it can ...

With the aid of nanotech materials, scientists have engineered a new way to convert the sun's heat into electricity that is roughly eight times more efficient than previously reported solar ...

Q: Based on our water bills, my family uses lots of water and much of it is probably hot water. Is there a simple solar hot water system design that I could build myself? A: Heating water can account ...

A saving of around £150 per year would give us a payback period of around 26 years on the capital cost of installing a solar ...

Installing solar power at a home is a great way to reduce electricity bills, especially as the cost of solar panels and their associated electronics continue to plummet. Not every utility allows ...

A British-Indian research group has developed an active cooling technique that is claimed to improve a PV system’s yield by around 0.5%. The system could be used in residential solar arrays and the ...

Desalination is being explored as a way to solve the shortages of drinking water that plague much of the world, but it has a few issues to iron out. A new design for a solar-powered desalination ...

A solar-powered mechanised water system has been commissioned at Wiesi, a farming community in the Builsa district to address water scarcity and promote peaceful coexistence between local residents ...
