The efficiency of solar panels depends on a large number of factors. The same panel can therefore perform better at one place than at another location. This creates a problem for the industry; how is the power of a solar panel expressed? The solution was sought in the Watt peak (Wp) unit. The power of solar panels is almost always expressed in this unit, which reflects the capacity of the solar panel under ideal conditions (25 ° C at 1000W / m2 light intensity). Unfortunately, these conditions are never met in practice.
Dirty solar panels immediately result in a reduction in efficiency. The company WAID provided several panels on a project in Wuustwezel with the Nano coating NITOGUARD GLASS SC. This coating has a self-cleaning effect in addition to the hydrophilic properties. The coating must ensure that the panels remain clean longer, the efficiency goes up and the cleaning frequency is reduced. The first results are amazing.
