Improving solar efficiency by 2.5% without capital expenditure

With ‘home grown’ energy at the forefront of everyone’s minds what if there was a way of getting an extra 2.5% efficient out of the UK’s 14Gw solar panels without capital expenditure?

Panels can only use the light that they can absorb and the two biggest issues that affect absorption rates:

• Reflection
• Dirt, dust and environmental pollution

Solar panel reflection or glare happens because panels are efficient at absorbing light perpendicular to them but much less efficient when the light is at a low angle (seasonally this occurs more in the winter). Glare is not only can nuisance to neighbors but is wasted revenue.

By using an anti- reflection coating Solar (PV) PanelGuard from Protection zone it is possible to increase light absorption by 2.5%.

The coating can be applied,as a finish on site or can be used to refurbish existing installations, especially older sites which may not have a anti-reflective coating incorporated within the unit. The coating can also be used on panels that already  have an inbuilt anti-reflective layer to increase the levels of light absorption and therefore energy produced.

Not only does  Solar (PV) PanelGuard increase light absorption through reducing the amount of light reflected but it also has the capability of keeping the cells surface free from dust, dirt, and air pollution. The nano-coating is hydrophilic and repels all particle

By using Solar (PV) PanelGuard cleaning becomes easier due to the repellent nature of the coating, the time between washdown can be extended.

The dual benefits of Anti-Soil of increasing light absorbance by 2.5% while repelling everyday dirt ensures a high return on investment over the lifespan of an installation.
