It's interesting, being on a flat roof without racking. Some installers will try to tilt the panels 15º to the south on racking. That's an expensive solution, but has two main advantages : reducing the penetrations of the roof to a minimum and getting about 10% more power annually. Advantage of this layout is that they don't shade each other, the space between is a narrow maintenance walkspace.
This one has each group of panels with their own watertight connections through to the roof structure. Very neat. I think there's a very small tilt to the south to roll water off. It's easy to clean occasionally, as the roof is on a single storey extension - and this is needed because rainwater will not self-clean flat panels.
Remember, that if you have panels and clean them yourself, use only the softest cloths, because you do not want to scratch the hydrophobic coating - the one that helps water and dirt to roll off.
Nice vegetated wall!
Thanks for this, did not realise they can install solar panels on flat roofs, I was thinking of getting some solar panels on my garage roof.
ReplyDeleteHi. I hope that the panels are gently detachable in case maintenance to roof is required. Also. They are at the Back of the house in a secure location. I am not sure about the wisdom of putting these on a part that is easily accessed from the public highway.
