According to a study by Duke University, North Carolina, if you clean your solar panels just once every 2 months, you can still expect around 25% to 35% loss in efficiency. You can read the full report at below :

In the UK, an average 250 Watts Solar Panel should produce 360KWh in a year.


Assuming a monetary value of 13.8 pence per KWh = 50 yearly total earnings.


We think that it is reasonable to assume 17.5 % loss in efficiency, if your panels are located in the UK and you clean them just once every 6 months. And we also assume a 35% loss in efficiency if you hardly ever clean your panels.


17.5 % LOSS X 50 = 8.75 LOSS per panel per year.
Total loss in earnings in 5 years = 5 x 8.75 = 43.75


35% LOSS X 50 = 17.50 LOSS per panel per year.
TOTAL LOSS IN EARNINGS IN JUST 2 YEARS = 2 X 17.50 = 35.00


However, with our manitenance system ( SPRINKLER + COATING ) installed, at an average cost of 30 to 35 per panel ( depending on the total number of panels, access to panels etc ), your ROI will increase. 5% loss in efficiency is assumed, since the Self-Cleaning Coating will clean the panel surface DAILY while the sprinklers can rinse the panel surface ONCE A WEEK.


INCREASE IN EFFICIENCY FROM 17.5% TO 5% = 17.5% - 5% = 12.5%
INCREASE IN EARNINGS = 12.5% X 50 = 6.25 Yearly.
TOTAL INCREASE IN EARNINGS IN 5 YEARS = 5 x 6.25 = 31.25 }5-Year Pay-Back.


INCREASE IN EFFICIENCY FROM 35% TO 5% = 35% - 5% = 30%
INCREASE IN EARNINGS = 30% X 50 = 15 Yearly.
TOTAL INCREASE IN EARNINGS IN JUST 2 YEARS = 2 X 15 = 30.00 } 2-Year Pay-Back.


Our Maintenance System can pay for itself WITHIN 2 TO 5 YEARS and after that, it will start generating you a clean profit. Also, you will no more be paying someone to clean your panels, saving you even more money.


The Coating and the sprinkler system are both guaranteed for 10 years and their life expectancy is 20 years +. There is an optional 5-yearly routine check on the sprinkler system for a charge of 250 Inc Vat every 5 Years.
