Investment and performance protection programme

Energy Gain ran a pilot for an investment and performance protection programme for Solar PV Systems. The results were outstanding: 19 out of 20 clients tested decided to take out a contract following the pilot. The programme ensures the maximum efficiency of your system by providing a full electrical inspection and solar panel maintenance, including cleaning.

“Since having my system maintained I’ve earned £320 more than my neighbour. Long may it continue!”

With Solar PV the profit arrives in the later years of the investment, so making sure your system is working well now will make sure it lasts, working to its optimum level and maximising the potential of your FIT payments. The average cost of this protection is as little as £10 per month.

Clean solar panels operate up to 30% more efficiently, so it’s very important to establish solar panel maintenance with an annual cleaning programme.

Sloping roof panels should be cleaned by the rain as they use self-cleaning glass. However dirt will tend to accumulate in the bottom corners of the panels so, as a precaution we recommend the panels are cleaned annually. This will ensure efficiency is maintained and output is not reduced.

Dirt on the glass covering the solar cells will absorb sunlight and as a result less light will penetrate through to the solar cell.

Google has a 1.6MW solar installation in California. It has carried out some research on the impact of dirt on panel performance, and on the impact of professional cleaning versus cleaning by rain. It concluded that panel output was greatly increased after they were professionally cleaned.

Investment Protection – Clean & Save!

Energy Gain UK invested in a solar testing facility in order to gather scientific data of solar photovoltaic performance data. We found that systems cleaned after one year against systems that have not been cleaned saw a huge 18% increase. The cost of this potential loss over 20 – 25 years is substantial.

The Energy Gain UK maintenance packages offer great value compared to other maintenance and service charges in the market.
