Honey Factory in Job, WV



Busy as bees......
These hives are the property of a new distillery, Still Hollow, that's undergoing construction in greater Job, WV.  Listening to the buzz from the sun warmed hives makes me think a bit about the frenzy of electrons  moving through a solar PV panel on a bright spring day!

Passivhause Solar PV: Garrett County, Maryland


Homeowners, Bill and Fran, opted to add solar PV as part of their new home.  They elected to build the house to a rigorous Passive House standard to minimize the energy footprint of the home and ensure that their new home would be comfortable and inexpensive to operate.

The 9-kW solar array is made up of thirty SolarWorld 300W modules.  The solar modules are mounted to the standing seam roof with S-5 clamps which eliminate the need for drilling through the metal roofing material.  SMA inverter equipment converts the DC power from the solar to AC which powers household circuits and turns the utility meter backward.   Special thanks to Larry at CHIPS Network for his help with connecting the inverters to the world wide web.  Production data like that shown below (sunny day in April!) is uploaded and stored on the SunnyPortal website.

"Webster couple improves off-the-grid living with small-scale hydropower" - Charleston Gazette

Micro-hydro in West Virginia gets a headline in the:

http://www.wvgazettemail.com/outdoors/20170119/webster-couple-improves-off-the-grid-living-with-small-scale-hydropower

Great article in Thursday's Gazette about the Janowski's hydro system in Webster County, WV.

Dave and I didn't make it into Rick Steelhammer's article so I gave us a little space here on the blog, although I think we're both a bit camera shy.😀  That's the ES&D turbine in the background that provides most of the power for Mickey and Jenny's off-grid home.

Home Power Magazine also featured the Janowski's home in their July/August 2015 issue.

Grid-tie Solar Power System with Battery-backup in Beverly, WV


Sixteen SolarWorld PV modules back-feed power to the electric utility during normal operation.  During an outage the battery bank and electronics in the basement supply power to selected critical loads.  The battery bank has eight large Trojan deep-cycle batteries.  The backup system can supply 21 amps (240V) and the stored power is close to 17 kWh.  In a prolonged outage the solar will help charge the battery bank as though the home were off-grid.

Sea Container as Off-grid Solar Power Plant - Somewhere in West Virginia


 5.4-kW PV on a 20' can.  Apple juice concentrate was originally imported from overseas in this container.

Outback Power electronics and Trojan batteries are stored inside.  The battery bank can provide 13.3 kWh at 50% DOD.  The inverter produces 120VAC with a max wattage of 3,500W.  There is a Trimetric battery monitor included to aid in the maintenance of the system

The system was built for West Virginia State University as a power supply for an agricultural project near Nowhere, West Virginia (or is that, Somewhere).  Wherever it is, it's out there and it's a long way to a utility pole.

Good Energy: Nik Botkin's Apartment Earth Art Studio

 
I had the pleasure of meeting Nik Botkin at his studio in downtown Charleston, WV while I was finishing up a solar project nearby.

I've had his business card on my desk since because it has a photo of a starling cast in a clear resin fish which I think is super clever.  Nik explained that he's made thousands of these resin fish often with bits of selected detritus inside.  His portfolio is online and well worth a look.  Likewise, if you are in Charleston his studio is a treat.

Davis & Elkins College: Spring Green-up on the Harper-McNeeley Auditorium Roof

 
Had a great student project yesterday with members of the Greenworks! Club at Davis & Elkins College.

 

They installed thirty 285-watt SolarWorld modules on the roof of the campus auditorium.  This builds on the twelve modules that were previously installed at the campus' science center last year.

 

The students at this small liberal arts college in Elkins, WV have, for the second year running, installed more solar PV capacity than any other residential college in West Virginia.  The enthusiasm and funding for their projects comes directly from the students.

 

Students initially identified locations on campus where they thought solar might be a good fit.  We met last fall to look at one of the better locations - the Harper-McNeeley Auditorium.  Turns out that the site was sweet!


It is always a pleasure to work with the D&E students.  They are hardworking, smart, and affable.  Our installation of thirty solar panels, thirty Enphase microinverters, and the associated wiring was polished off in record time.  Everyone ended the day sun-kissed and pleased with the result.
