The Spanish company Onyx Solar has launched the first photovoltaic ‘low-e’ glass, which can generate electricity costing up to 90% less than energy purchased from the traditional utility grid.
The glass from Onyx Solar has the same properties as low-e (low emissivity) glass, but can also generate clean, free energy from the Sun.The first photovoltaic low-e glass to hit the market has a solar factor of between 10% and 40%, allowing for optimal internal temperature control and therefore large savings in heating and air conditioning bills.
