We thought this was interesting – a nice merge of design and sustainability:
The glass roof tiles by SolTech System mark a revolutionary and award winning method of integrating solar energy into any building. Instead of traditional roof tiles made of concrete or clay, these tiles are made of glass, allowing the sun to shine through onto the absorbing surface underneath. According to Inhabitat, the energy generated is integrated with the building’s existing heating system or electrical grid. A major advantage of the SolTech System is that it does not need bright sunshine to work, which means that it also generates energy on a day with slight overcast.
Check it out! I want a sweet looking rooftop system and this is a better design than the normal panels!
