SurfaShield® G

SurfaShield® G is an innovative self-cleaning coating based on proprietary nanostructured Titanium Dioxide (TiO2) photocatalytic technology for existing photovoltaic installations. It acts by reducing the amount of sunlight reflected off solar panels, absorbing more of the diffused light and preventing dust, soot or dirt accumulation.

The super-hydrophilic nature of SurfaShield G adds easy cleaning properties and minimizes maintenance costs.

1MW Solar Plant in Spain:

Features:

    • Nominal Annual Energy Output: 1,502.334MWh
    • Expected Energy Output Increase: +6% (+4% guaranteed)
    • Expected Extra Income: 20,000 – 30,000 € annually
    • SurfaShield G Material Needs: 180L
    • Investment Payback Period: Less than 12 months
    • Expected Investment Lifetime: >120 months

Application:

Application takes place by spraying (fine mist). It is easy to allign application in both the production of photovoltaic systems as well as on already installed PV systems by using portable spray guns or even drones.

Consumption rate: 35 m2/L

Advantages

More energy is generated.
Water consumption (maintenance) is reduced.
The investment in renewable energy sources become more attractive.
170m2 of surface treated with SurfaShield® G eliminates airborne pollutants ~ 1 adult tree.
Environmentally friendly – Biodegradable product.

Energy Increase

SurfaShield® G treated panels produces 5-8% more energy than untreated panel.
