Tue. (The Big Day) Got to Dennis early and met up with Mic, Geoff, and Third Sun crew.  Geoff remembered me from the wind project.  Colin and Alex showed up soon thereafter and we went to work unpaking and cleaning the PV panels and then transporting them up to the roof.  They are pretty bulky transport and it makes me nerveous to carry $900 equipment up a flight of stairs.  After we got all the PV panels unpacked, I helped paint the platform in the display case and then assisted Geoff with the Outback conditioning equipment setup.  Meanwhile Colin worked with two other Third Sun guys installing a DC breaker box on the roof and running conduit from it through the third floor ceiling and down to the breaker box in the Green Zone.  The day was long, but I feel like I developed a much better understanding of the PV conditioning gear and how to set it up.  I'm looking forward to when we can finishs hooking up the panels and go online.

Wed. We met at the farm to test out our hot water unit.  Colin had already installed one bleeder to fill the water loop.  Dan put in a second in the basement and we filled the loop and evacuated all the air bubbles.  Too bad it was so late in the day that we really didn't have much heat to work with.

Sat. got up at the crack or dawn to drive out to the Kicks 96 radio tower with Mic, Charlie and the crew and meet the folks working on setting up anamometers in preparation for an RP&L wind farm.  Met Mayor Sally Hutten and Bob Weatherspoon, both very sharp folks.  After the radio tower party, we went back to the farm and discussed the details for reusing the tanks and installing out hot water system on the roof.  Looked online and found information on Thermal Store water heating systems and heat exchangers.

**During class on Tuesday we discussed the plan for testing the solar hot water unit with Charlie. © Charlie: remember KISS, keep it simple (I think the second S is for "safe", Charlie didn't say ;).  We discussed the components that we would need, and Kate and I agreed to go shopping.  Charlie wants the test up and running by Tuesday next.

**Tue: Kate and I purchased all of the supplies on the list (hoses,water pump,copper piping, 10# wire, etc.) from Mendenhal's and TSC.  We used a 10% off coupon at TSC that I'd just recieved with the Pal-Item.  I hope it doesn't take too long to get reembursed.

**Sat. met with Kate and Colin at 10 a.m. to start setting up the hot water test.  We worked for about three hours.  Colin and I had to run to Mendenhal's  again to pick up a soldering torch and a junction box, then we swung by Charlie's office to pick up the 64 Watt PV panel he had there.  We got the copper coil in the barrel and sweated on the hose connectors.  We also got the hoses hooked up the solar hot water unit and ran water through to make sure the system was clear.  We hit a snag when we noticed that we would need a special adaptor for the pump before we could get it hooked up to the PV panel, but Kate did find the specs for the Pump online and it seems that it should be fine with only the 3-4 amps that the PV panel will output.  After we put the pimped-out barrel in the basement we called it a day.  I drove over to TSC and picked up the adaptor we needed, along with some hardware to mount the PV panel and an extra 25 feet of 10# wire.  We're meeting tomorrow to finish the setup.

**Sun. we managed to get a lot done in about two hours today.  Dan was able to help, and we built a functional stand for the solar panel, ran a line from it to the basement and got the pump hooked up.  Unfortunately the hose attachments for the pump were too small.  Colin is going to run out to TSC tomorrow and finish up that piece.  We also need to figure out how to fill the closed loop and remove any air bubbles.

**Met with the crew on Tuesday to finish up the hot water audit.  Colin had a nifty little kilowatt-hour calculator written up using the data from the hot water heater user guide site, but looking at the results (102% efficiency) it was clear that something wasn't right with the numbers.  We first corrected the fahrenheit to celsius calculation and then, still noting problems, scrapped some of the calculations from the website and found an online source for converting joules into kilowatt-hours.  After that Colin's program worked great.  I suggested he rewrite it to take as input the standard recharge rate of hot water heaters so that it might be more useful to other interested parties.

Discovery: Having a job that says that you are "on duty 24 hours a day" does not lend itself to getting a lot of classwork done. oops.

I'm guessing that the Gr-01 is what we're looking for. Our panel is a Solarex Mx64. Solarex was bought by BP. Not sure if current mounts are backwards compatible.

Tue. (The Big Day) Got to Dennis early and met up with Mic, Geoff, and Third Sun crew. Geoff remembered me from the wind project. Colin and Alex showed up soon thereafter and we went to work unpaking and cleaning the PV panels and then transporting them up to the roof. They are pretty bulky transport and it makes me nerveous to carry $900 equipment up a flight of stairs.

Meanwhile Colin worked with two other Third Sun guys installing a DC breaker box on the roof and running conduit from it through the third floor ceiling and down to the breaker box in the Green Zone.
