London scientists have unveiled a new solar hybrid system for homes Bashny.Net

Quite logical would be to think that the more sunlight strikes a photovoltaic panel, the more electricity is produced. However, in practice it is not so – the solar cells under the action of solar heat to heat up and lose some of its effectiveness. But scientists from the Brunel University in London has invented a new application of solar heat, solar heating panels, they created a hybrid system that turns the entire roof into a solar generator.



 
The patented system combines a flat heat pipe with photovoltaic cells so it not only generates electricity but also heats water. The heat pipe used for removing heat from surfaces of equipment and equipment that must be maintained in a refrigerated condition (e.g., personal computers, data centers, etc.).

This system used a flat heat pipe, with dimensions of 4mm x 400 mm, which optimize the collection of solar radiation. Removing the heat from solar panels, heat pipes to prevent overheating of the photovoltaic cells and thereby maintain their effectiveness on the proper level. During testing of the hybrid system, scientists have discovered that heat pipes contributed to the cooling of solar cells by 15 percent, compared to the standard cooling mechanism used today in roof-top solar installations.





Currently, a prototype of hybrid solar systems are tested by scientists on a standard two-bedroom apartment building in the Institute building in Watford, UK. Already, they noted some interesting features of the system. Thus, the heat pipe proved to be so effective that they could capture energy from the morning dew evaporating from the surface of the panels.

It is hoped that this efficient and productive system in the near future will be available on the consumer market. published
