Manufacturer's Description

Even though the solar cells are very cheaper now we are not able to harness the solar energy to the limit we can due to certain reasons such as low efficiency of panels, huge area required for installation of panels and decrease in performance of panels over the time due to accumulation of dirt and dust on panels. There are reports that the efficiency of current panels decrease up to 40% within a week due soiling. Cleaning of a panel requires at least 3 liters of water and cleaning charges are additional.
We have developed a cheap and durable “anti-soiling and anti-reflective coating” for solar glass cover. This coating enhances the transmission of light to the silicon wafer and hence increases the efficiency of panels as shown in figure here. This coating reduces the soiling up to 99% and hence will save cost of cleaning as well as prevent unnecessary wastage of water. We are the first and only to develop this technology in India. Both the precursor solution and assembly has been designed and developed by us and are patentable. Important factor and a challenge before the adoption of any technology is cost, we are much cheaper than the foreign players.
