Re: [RE-wrenches] Microfractures in PV Modules

Does this suggest that it is better to buy monocrystalline cell modules instead of poly; and that those modules that flash test with the highest output for a given production run have the best printed connections and therefore the higher probability of long term life and performance? Bill Dorsett

[RE-wrenches] Fall Protection Recommendations?

2014-10-05 Thread William Dorsett
The Home Depot safety harnesses are very clumsy to work in, difficult to adjust for different workers and don't easily adapt for multiple workers. Is there any consensus as to the best safety equipment for a crew of four or five on a roof? Thanks all. <>_

Re: [RE-wrenches] offsetting generator loads with PV

Hi Jerry, Most of these sites have intermittent grid and onsite full sized generators. When the grid is up, it supports net metering. So I'm hoping to be able to program inverters for grid tied and generator tied. When the grid is up, it is a large scale grid. thanks, Conrad On Sun, Oct 5,
