Solar panels and roof load question
Comments (2)Hi, If I understand you correctly, the new panels would apply their loads to new rafters that are not currently loaded by the existing panels. If that is the case, then it seems like if the current panels are OK, the new ones should be OK as well since they are not adding load to the same rafters the current panels are on. You could noodle around these pages and maybe get some help from the info they provide: http://www.awc.org/technical/spantables/tutorial.htm http://www.awc.org/calculators/span/calc/timbercalcstyle.asp On the span calculator at the link above, if you use 2X12s at 24 inch spacing, deflection = L/180, with the 20 psf snow load plus 10 psf dead load (ie the roof) you get a max span of 21.25 feet. If you increase the dead load to 15 psf to cover your panels (actually more than cover them by quite a bit), the allowed span goes down to 19.75 ft -- not exactly a killer change. You could compare the numbers the calculator gives to your actual span and see how (roughly) how much margin you have. Gary...See MoreInstalling Solar Panel on Chemwood Roof
Comments (1)Some solar installers do that with fragile roofs - clay tile, where they remove a good chunk of the original and put down composition shingle. Depending on how things are done, there could be problems for the lower portions of the roof if the water run off is channelled between the roofing felt and the chemwood roof....See Moreattatching solar panels to tile roof-advise please
Comments (12)We too have the same as Ralph, Heliocoil. In fact I think it was at Ralph's recommendation-thanks Ralph! The way it was explained to me, after a while the straps on the fafco system deteriorate and you get "flying panel syndrome". We've had funnel cloud warnings and still no problems. Plus in 10 years when the panels start to deteriorate the company will send you a 1/2 off coupon for more panels I'm told. As far as unsightly, our CCR's in California do not apply to Solar and we can put them anywhere we want even in our gated neighborhood. However as a good neighbor we put them across the back of our tile house. You do have a good view from the park across the street but if we ever sell and people think they are ugly, they can always take them down. As for me, I'll enjoy the 83 degrees my panels made my pool today and know I am not contributing to global warming by heating my pool. (of course I'm sure the four pool pumps aren't helping the environment, but no one is perfect right?)...See Moresolar panels penetration of roof
Comments (15)millworkman and Stax: Let's give a little leeway on the spam accusation please. If a person gives a good answer, which Mini did, and it's related to the post in question instead of starting one on his own, I wouldn't qualify this as spam. Anyone who thinks that posting their business here is going to result in a crush of new business is sadly mistaken anyway. I've been here 8 years or so, have contributed substantially, have been thanked profusely, but that's resulted in a few $300.00 paying jobs and a Starbucks gift card. Not a way to build or run a business. I get a private message nearly once a week asking for free advice, to which I always respond, so this spam thing goes both ways....See MoreAnnie Deighnaugh
