Re: [RE-wrenches] Flat Panels

It's not as simple as tilt angle. Modules in Los Angeles (34 degrees latitude) at 35 and even 45 degrees tilt get dirt buildup caused by night and early morning dew and dust and no rain to wash the buildup. Flat roof arrays stay fairly clean in locations with regular cleansing rainfalls.

Re: [RE-wrenches] AC coupling

Dave Katz sent a drawing which breaks the AC connection between grid-tie inverter and battery based inverters when the battery voltage is high.I've seen similar sketches from others. Thanks as always, Dave...but it seems that in this arrangement the amperage to the battery is either 100% on

Re: [RE-wrenches] AC coupling

I should have also mentioned that the dump or diversion control can be done via an AC load with a relatively inexpensive AC solid-state relay and AC loads such as AC baseboard or AC electric water heater elements - which are much easier and less expensive than doing it with the lower voltage /

Michael, The Solar Energy Industries Association (SEIA) has had Ward Bower, of Sandia National Labs, as their voting member on the Code Making Panel for many years. This fall, I was appointed by SEIA to be Ward's alternate at the meeting. We both attend the meeting, but Ward is the voting

Re: [RE-wrenches] Flat Panels

Joel and Bill - Interesting dialogue... My point was that flat panels won't wash off in the rain because heavy sediment (dirt) can't flow over the module lip. Instead, it continues to build up to a point where it clouds rows of cells. This is what we see here very clearly in San Francisco. It

Re: [RE-wrenches] Flat Panels

Don't get me wrong. Flat panels get dirty and raised frame edges collect dirt. Monitor the system output to determine when to wash the array. The economic trade-off is kWh lost to dirt vs. cleaning costs. - Original Message - From: August Goers [EMAIL PROTECTED] To: 'RE-wrenches'

[RE-wrenches] hydro coils

I have a client that is wanting to add a water loop in their wood stove. Does anyone know if the old SS hydro coils are still made? Todd -- Todd Cory KE6SXS [EMAIL PROTECTED] mailto:[EMAIL PROTECTED]* Mt. Shasta Energy Services License C-10 #811428 P.O. Box 689 Mt.
