Clean Solar Solutions Ltd has completed the cleaning of 250KW of solar panels on a privately-owned commerical rooftop in Birmingham.
The 249.75KW solar array was installed in January 2014 and is made up of 999 ReneSola JC250M-24/Bb solar panels mounted on the Clenergy EZ-rack and has 8 x ABB 27.6TL inverters and 1 x 10TL inverter.
Although the system cost about £240,000, it is expected to yield £42,000 p/a and pay for itself within 7 years, proving that rooftop solar arrays are both an excellent use of redundant space and are profitable for business owners to install. There is a common misconception among the public at the moment that solar is not a worthwhile investment. However, if calculated correctly, solar can still offer excellent cost savings to heavy consumers of power.
Keeping the solar panels clean is an important part of helping the array hit that 7 year target. There are a number of reasons why the solar panels will need cleaning on this array. Because the solar panels are mounted at a relatively shallow angle, they hold more dirt than those mounted at a steeper angle.
The M6 in this area of Birmingham is one of the busiest stretches of the M6. The motorway is only about 400 yards away from the array and is at the same height as the roof of the building. Traffic film will accumulates over time and will inhibit the output of the array if it is not cleaned on a regular basis.
There is also a local population of seagulls, no doubt ‘Beaky Blinders’ (we couldn’t resist!) which make a mess of the solar panels with their droppings. There was a considerable build-up of bird droppings and some were very stubborn to remove. Bird droppings create ‘hard shading’ on solar panels and can if left, reduce the output and have other effects of bird droppings on solar panels.
