The sun's energy drives nearly every
element of life on this planet.

One of the biggest environmental opportunities scientists are addressing is how to efficiently harness that energy in a form that mankind can readily use, store and transmit.

Generating energy from the sun, whether as Heat (thermo Solar) or Electricity (Photovoltaic Solar) is an engineering chain reaction that starts with the behaviour of light as it strikes the cover (Solar Glass) of a solar energy device.

Three key variables drive the performance of Solar Glass:

  • 01 Light
  • 02 Time
  • 03 Price

01 Light reflected is energy wasted

Light reflected at any of the surfaces of a solar energy device is effectively an energy opportunity wasted. This problem is particularly acute for devices situated away from the equator, where often sunlight strikes the solar glass at an oblique angle and is reflected away, rather than transmitted through, to the energy generating components of the solar panel.

When compared with currently available solar glass, an Optitune-coated solar device can reduce reflection by up to 75%; this leads to a 3% to 4% increase in light energy reaching the generative elements of the solar panel.

02 Time is money

Typical solar glass coatings start to de-laminate and "yellow" within three years of installation; any degradation in the surface integrity of solar glass reduces the energy potential of the device.

Optitune nano-scientists have created an anti-reflective polymer that is extremely hard, and can withstand the ravages of extreme heat, cold and abrasion.

03 Price matters

Most commonly available solar glass is low performance because it has simply been too expensive to apply extremely hard, optically excellent coatings on to solar glass. Optitune has solved this problem.

Optitune reduces the material and power usage costs of coating solar glass by up to 80%, when compared with the commonly used batch processing techniques of high temperature vapour deposition. Optitune coatings are applied in atmospheric conditions via spray, dip, roller and slot coating techniques: better for the environment and better for the price performance of the solar industry.
