[RE-wrenches] 14 PV-Powered Fans- best method?

Hi all, I'm working on a project for a state park, where they're looking to add some PV-powered fans to a outdoor bus stop. The customer is hoping to have the fans spin more quickly as irradiance increases, and they want a master cutoff switch. I'm initially planning to use 2 10W modules

[RE-wrenches] Wind Lift on ETC round tubes

Does anyone have wind lift data for round tube evacuated SHW collectors mounted flush to a roof? We are looking at installing [5] - 30 tube APRICUS collectors in a row. APRICUS has models for the rack installations but not for flush to roof installations. The 3 second wind burst is 90 MPH.

Re: [RE-wrenches] Subterranean solar panels

A compact optical device would still have to work with the sun's energy at 1000W/square.meter, and even if they could get 20% conversion efficiency (highly unlikely), it would still need to cover an area of more than 5 sq.meters per kW output. Not very compact' Brian Teitelbaum AEE Solar.

Re: [RE-wrenches] Insulation testing

I'd like to see if we can complete the thread on insulation testers (Meggers). Below is a copy of Bill Brooks last posting on this subject from several weeks ago. Bill says the keys are to use the tester and in performing the tests properly and safely which requires test procedures. What are
