When you think of solar roofing, you think of big panels on your roof, right? And you think, the more sunlight, the better, but that is not necessarily the case. A system is being tested that not only doesn't need all that sunlight, but can actually capture energy that the early morning dew evaporation from the rooftop can generate.

How does it work?


Efficiency decreases when photovoltaic cells or the cells used in solar systems, heats up. There is heat that is let off that should be used. If you could take that heat and use it as a generator, you could do more with it.
The heat that generates in the summer needs to be stored for later use. Insulating a house is not the solution because it merely lowers performance by trapping the heat.

Brunel University in London

Brunel University in London has a team of scientists working on creating a hybrid system. In essence, the roof becomes a generator by combining PV cells and flat heat pipes that generate electricity using both water and heat. The heat pipes are approximately .4 cm by 40 cm and are flat. The extra heat that the photovoltaic cells generates is used by the heat pipes who transfer the heat away from the places that they don't want it. Data cooling centers and personal computers make heat that they don't want. The heat needs to be moved away from the computers and cooling centers. The heat pipes pull that heat away, cooling the PV cells by 15 percent and can heat water.

In Watford, the Building Research Establishment is currently testing the system on a three bedroom house. This prototype has already had positive results.

The pipes are easy to install.

The solar panels need to face south and are easy to install. Just click together like a laminate floor and they become weather-tight.

Cost

The cost of these pipes may be very expensive. They are still in the testing phases so the cost is not really known yet. But when the time comes, a homeowner would have to weigh the cost of the pipes against the savings and then against the cost of traditional solar panels. You might even need to compare the difference in normal roofs versus a different type of roof that you may have. Also, would it make a difference if the pipes were on the roof or the ground? Would it be more cost-effective in the long-term than short term with each example?
