Mother Earth News Fair 2012 Solar Presentation

These are the slides that backed up my solar presentation at this year’s MEN Fair in 7 Springs, PA last weekend. There’s some text in the basic solar section, but they’re mostly slides. Primarily examples of things you’ll need to do/file/apply for if you are contemplating a DIY solar project. All the things I help out with if you sign up as a DIY solar client!! Also includes some great pictures of a variety of ground mount systems that I researched 2 weeks ago while attending the Solar Power International trade show in Orlando Florida. Please feel free to download and pass this around. No problems with that at all…

What it takes to keep your power UP when the grid is DOWN!

It’s been a long time coming, and I’ve been hesitant to make the investment, but recent power outages caused by the weather, combined with the state of affairs around the globe, have given me the motivation to finally make it happen. Please come back here at least twice a month to check my progress on this project! I’m doing this at my “bunker” in the mountains of Ohio. I’ve already got a 2400 watt system running using the older Enphase M190 micro-inverters along with 12 assorted PV Panels, and it’s covering 90 to 100% of the electric bill. But, I lost a refrigerator full of food when the power was down for too many days… so, I’m adding all the parts to keep the power flowing when the grid is down! Here’s a list of the parts I’ve got on the way:

  • Magnum Distribution panel 250/30A-2P
  • Magnum MS-PAE 4024AE 4kW 240VAC Pure Sine Inverter
  • Magnum LCD Remote Panel (for programming and monitoring inverter status)
  • Magnum BP-MMP Metal Mount for MMP enclosure and inverter
  • ROLLS 6V 530AH Wet 40000S EKG Battery (X4=24 Vdc)
  • Battery Box fan 24volt, 6 CFM
  • ROLLS R+ Recombination Caps (X12) keeps battery watering to a minimum
  • Outback Spill Control Tray for the batteries – in case of a case crack or acid spill
  • #4/0 gauge flex wire with lugs for battery interconnections and inverter hookup

There’s also a whole house SMART SWITCH and some other parts to modify the incoming service wiring…

That pile of parts is worth about $4500 if you’re considering doing this. Well worth the price if the grid goes down for ANY reason! I’ll take pictures as I go and do updates to describe my trials and tribulations!
DIY Solar is affordable and reliable ( and a great way to prepare for Zombie Armageddon ) just kidding… and have a SUNNY day!

Working on a 10/12 pitch asphalt shingle roof

steep 10/12 pitch roof

Time and Patience needed when working a steep roof like this!

Rich's climbing skills were priceless during the initial stages of the installation

Oh my goodness!!! The pictures looked like a nice easy 6/12. When I got up on the roof I IMMEDIATELY realized it was more like 10/12. That’s JUST SHY OF 45 DEGREE SLOPE! Almost perfect for our 39 degree latitude in the Cincinnati area, but NOT MUCH FUN to get started.

We set 90 feet each with two 3 1/2 inch lag bolts and a 3 inch spacer (Unirac-I product) and that took from 8AM till 1:30 PM. The feet made navigating the roof much easier, since there were at least some footholds to stop from sliding. Of course, I had my OHSA approved harness and rope line on. It was like cliff climbing!! We managed to get two panels in two rows on a small shade room addition mounted as an instruction area before having all the helpers tackle the 10/12 pitch roof!!

I wasn’t about to go up/down any more than I needed to, so I didn’t get any pictures today, but I’ll be back to finish the job tomorrow, and I’ll come home with some spectacular pics to add to this section!!

17 panels on the 10/12 pitch; one row of five, one row of seven, and the bottom row is five in landscape style to fit the trapezoidal roof section. One row of five panels on each side of a 3/12 pitch shade room roof facing north south, but still exposed to LOTS of sun.

NOT A TREE BLOCKING THE SUN FROM ANY DIRECTION!! This guy will make MULTI-MEGAWATTS of solar power! See ya’ll tomorrow when I get back!

FInished installation 17 panels on main and 10 panels on sub roof. 6345 watts!

27 Renogy 235 watt panels provide 6345 watts of solar power
