arthur49 Posted October 26, 2009 Share Posted October 26, 2009 Hi Can't find anything using Search facility. About to fit solar panel on roof and also want to fit a small wind deflector on roof in front of it. Sikaflexed to roof. I know some have already done this. Any tips on materials used and if necessary, how did you mould it into shape? Many thanks Arthur Link to comment Share on other sites More sharing options...
Derek Uzzell Posted October 26, 2009 Share Posted October 26, 2009 Fiamma markets moulded plastic 'spoilers' in 40cm or 60cm widths and about £10 or £14 respectively (available from CAK). Otherwise, you could just use an appropriately-sized piece of thinnish aluminium sheet bent to an angle so that the slipstream would be deflected over the solar panel. It would be possible to produce a bespoke deflector in GRP, but you'd need to know what you were doing and it would be expensive if you didn't already have the materials. (Are you sure you need to do this? Unless the solar panel is well forward where the slipstream will clearly hit it, I'm doubtful that fitting a spoiler will have much value as far as wind-deflection is concerned. Might give some (small) protection against hanging branches though, I guess.) Link to comment Share on other sites More sharing options...
colin Posted October 26, 2009 Share Posted October 26, 2009 If I was doing it would be 24swg aliminiun, two folds to give 30deg slope and two flats, etch primed and painted, stuck to roof and panel, at both front and back, but we have all equipment and off cuts at work to do the job. Try a local small sheet metal workers, if we need small amount of commercial material cut and folded it's cheaper for us to go to T&P sheet metal and get them to do job with whatever they have on shelf.

arthur49 Posted October 26, 2009 Author Share Posted October 26, 2009 Thank you for input gents. Panel will be well forward, but narrow end to front, and I may have a go at deflecting wind from underside of panel. Arthur Link to comment Share on other sites More sharing options...

Arthur If you fabricate one like this, you will need to have a cut-away at the corners to ensure and water is not able to disperse from under the deflector.

colin Posted October 26, 2009 Share Posted October 26, 2009 Maybe my post wasn't too clear here's a drawing, ends would be open giving a small amount of turbulance. Link to comment Share on other sites More sharing options...
Syd Posted October 26, 2009 Share Posted October 26, 2009 Deflectors also prevent tree branches from getting underneath the panel and ripping it off Link to comment Share on other sites More sharing options...
arthur49 Posted October 27, 2009 Author Share Posted October 27, 2009 Thank you Cloin for drawing - that looks a good option. Arthur Link to comment Share on other sites More sharing options...
Mickt Posted October 27, 2009 Share Posted October 27, 2009 Don,t block in completly as you need air underthe panel to keep it cool Link to comment Share on other sites More sharing options...
