Story SolarInstall created by Michael Newman

Solar panel installation at Wildstar farm. There are 54 panels going on the roofs for a 17.6 kw system. Construction started July 15, 2013. The installation was substantially complete a week later. A long delay occurred for NSTAR to receive all of the approvals and to install the new pole and transformer they required. The pole was installed on October 3rd and approval to interconnect was received on that day. The panels started generating power on October 4th 2013 and the meter showed a 1Kwh gain by sundown.

Solar Generation total solar power generated and power usage is collected by a Solar-Log meter. (Consumption includes the cottage.)

Cottage power consumption is reported by a SunBug meter installed in the cottage.

This site plan shows where the panels are located and how the power is routed back to the power feed at the south east end of the house.

The solar panels and inverters (in the rightmost garage) were delivered a few weeks prior to the start of the installation.

The 54 panels go on the roofs of these two sheds and across the breezeway between them.

Patrick is considering how to mount the inverters. They will go somewhere on this wall of the eastern stall.

Inverters and meters go on the wall of the building.

Inverters, breaker box and the solar meter are now completed.

On the second day racking is installed on the second stall roof. The racking is also adjusted so the panels will butt to each other on the three planes, west stall, breezeway and east stall.

Racking is completed.

The first panel goes up on the morning of day 3.

Only a few panels left to go.

Panels on the breezeway. The plan is to tape over the gaps to make a rain proof roof.

The completed solar array. Now on to the wiring.

Solar production goes over the top of the stalls to the cottage and then to the garage.


IMG_20130718_081551_556



Solar production goes down one of these conduits to the cottage. The smaller conduit carries 110 for the stalls in one conduit and internet for the solar in another. There is a spare 2 inch conduit.


IMG_20130718_081115_105



This conduit runs from the cottage to the garage. This is the cottage end. It carries the the electrical circuits for the cottage as well as the solar production circuits.


IMG_20130718_081056_242



Here is where the Solar wiring and power from the cottage comes up in the rear of the garage. From here the conduit will go over the ceiling to the front of the garage.


IMG_20130722_191104_711



Once we were comitted to a trench for the solar feed to the house one conduit was put in for the solar power and three spares were put in to support network, phone etc. Here the lines meet the house.


IMG_20130722_191116_150



Turning around you can see the lines running down the driveway to the cottage.


IMG_20130722_191336_598



They go around the corner to the back side of the cottage.

The original plan was to use the 3 inch conduit aready installed for the electirc feed to the cottage and for the solar. Now that conduit will only be used for the cottage power.


IMG_20130723_183654_443



A day later a foot of rain fell and the open portions of the trench got a bunch of water. Note the perimeter drain from the cottage. Also note the clay basement drain and the white sump drain. Not sure were these come out. We suspect that the sump drain is interrupted by the sewer line.

The old hole was not deep enough or wide enough for the new pole.


IMG_20131003_111502_995



Lots of rocks in the hole forced opening the hole the good old fashioned way.
