Were can I get some thin strips of metal that I can screw onto the roof to hold a pipe?

We Answered:

Any hardware store should have what you are looking for. However, I do not recommend screwing anything into a sheet metal roof with out proper flashing. Caulking, though it is widely excepted as a waterproofing agent, tends to break down faster then the lifetime of any roof. I assume you have a standing seam roof? My suggestion would be to clamp the pipes onto the seams instead of creating any penetrations in the roof.

Best of luck,
Rick

Can I Make Solar Powered Model Airplane.....Using Silicon cells ......keeping them in wings and tail?

We Answered:

Your primary need for solar cells is in an aircraft, but your question is purely an electrical one...no relation to aviation at all. An experienced electrical expert who has experience with solar power will be able to answer it. Even aircraft maintenance engineers will not be able to answer your query because solar cells aren't used commercially by Airbus, Boeing or any other company.

Post your question in the category Science & Mathematics > Engineering/Physics section and I'm confident that someone expert will be able to answer your question.
