A nano coating with self-cleaning and hydrophobic properties for photovoltaic (PV) and solar thermal panels. The solar panel coating's self-cleaning properties stop dust and bird faeces from sticking to PV panels, keeping them clean, maintaining their efficiency, ensuring the maximum amount of electricity is produced. The hydrophobic properties repel water more quickly than uncoated “self-cleaning” glass as found on typical PV panels. This makes coated PV more efficient during inclement weather.
Dirty glass can render PV up to 25% less efficient. In certain situations the whole string can be switched off due to excess dirt. The solar industry recognise this as a major issue and recommends photovoltaic panels are cleaned every three months or more regularly in dirty environments. This ensures the maximum amount of electricity is produced. However, many PV and Solar Thermal installations are on roof tops, requiring specialist companies with scaffolding to access them. This can prove to be cost prohibitive leading to less electricity being generated. Solar PV, nanoShell's Solar Panel Coating is the solution.
An easy-to-apply nano coating for DIY or installer application, nanoShell Solar PV stops dirt and bird faeces from sticking to PV and Solar Thermal panels keeping them clean for up to 4 years. Not only does this mean that PV cells treated with nanoShell's Solar Panel Coatings are kept cleaner for longer, but coated panels can be used in environments previously considered inappropriate for their use. If installed in a particularly dusty environment or in an area of low annual rainfall then some cleaning may be required. This is typically achieved using an ionised water system as employed by most modern window cleaning contractors or through the installation of an automated sprinkler system.
Surfaces such as those found on most PV with “self-cleaning” glass is less effective in repelling water than those coated with nanoShell's Solar Panel Coatings. Water spreads over the surface in non-coated installations; this reduces the amount of light transferred to the PV cells and leads to less electricity being produced.
The hydrophobic surface provided by the invisible coating nanoShell Solar PV repels water, forcing it into near-spherical droplet structures. Droplets roll off the sloped PV surface more efficiently than water on uncoated surfaces. Therefore, the performance coatings reduce the negative impact of rain on panel efficiency. PV coated with nanoShell Solar PV produce more electricity in rainy conditions than non-coated PV. In one week alone, coated PV produced more than 20% extra electricity than non-coated panels at Philip House in Exeter.
nanoShell Solar PV's self-cleaning properties stop dust and dirt adhering to the glass surface. The hydrophobic properties repel water, increasing the amount of light transferred to the PV cells. The droplets created as a result of this hydrophobic effect roll off the PV collecting dirt as they go. PV coated with nanoShell's Solar Panel Coatings stay cleaner for longer, ensuring maximum efficiency is maintained. They incur much lower cleaning costs and produce more electricity in wet conditions than the equivalent non-coated panels.
nanoShell Solar PV saves you money and makes you money.
