Note: While this page shows how I wired my solar panel system,
I wouldn't consider it a guide to installing your own system - I'm still relatively
new to the alternative energy field and haven't had substantial time to field
test my setup.
| Immediately after placing the order
through Sundance Solar, I went to work planning for the arrival of the
system. The greatest challenge of the entire setup was to be where to mount
the panel. Living in a college residence hall presented the greatest challenges,
as I would not be able to permanently attach anything to the structure
of the buildings. This made mounting the panel, not wiring the setup, the
most difficult task in my mind. I initially explored options to gain access
to the roof the building, in which case I could just drop the wiring
from the panel down to my window (I was living on the top floor). However,
the roof access was secured by a padlock, and I didn't want to place the
panel in an inaccessible location, so I could clear it off after a snowstorm
(the system being so small I needed to maximize the |
| amount of energy
I was able to collect). I decided against the roof and after realizing
there was no place to mount the panel outside of my window, decided it
had to be mounted on the balcony of our suite. You can see the layout of
the suite on the right. |
|
 |
The solar panel would be mounted
on the balcony, then wiring would be run outside from the panel to my window
(I have the second single from the right in the picture). All the rest
of the equipment would be installed directly within my window. How would
I attach to solar panel to the balcony? The only option I could think of
was a platform that extended from the balcony. I set to work with a pen
and paper (and the use of some basic high
school geometry) and calculated out the size of the boards I would need,
how they would be attached, and the angle at which the solar panel would
sit.The materials I needed would be available from the local Home Depot,
which was a bus ride away, and I complied a list of what I |
| would need. Since I had ordered
the solar panel on Wednesday, and it would only take |
| one day to arrive from New Hampshire,
I figured it would probably arrive on Friday, assuming it was shipped on
Thursday. |

side of the building to my window. My window is the second one. |

Delays I
woke up Friday morning with no e-mail regarding the shipment of my order.
I knew this probably meant it hadn't shipped, and I fearfully
called Sundance. The clerk confirmed that the order had not shipped,
but it would go out today. The problem was that the order was coming
via UPS Ground, and UPS, unlike FedEx, did not leave their facilities
open on Saturday for package pickups. I asked Sundance if they could
mail the shipment FedEx, and I was transferred to Ed, who told me they
gladly
would
I would just need to schedule a pickup. I called FedEx, then UPS. The
problem was, while FedEx Home Delivery
(the residential arm of FedEx Ground) delivered on Saturdays, they
needed at least one business day notice for a pickup request. FedEx Express,
however, did offer same day pickups. However to have Express deliver on
a Saturday (with either FedEx or UPS) one needed to use their
most expensive
service,
Priority Overnight.
Solar panels and batteries are heavy, and to have everything shipped
Priority Overnight would cost me upwards of $60 with the Saturday delivery
fee (as
opposed to the very reasonable $14 Sundance charged me for Ground).
I called Sundance back and asked them to ship the order via UPS, but
also
confirmed
the dimensions of the solar panel, so I could at least build the platform
for the panel over the weekend; wiring the system which would have
to be done on Monday wouldn't take more than an hour by my estimates

The
Supply Trip With the system not coming till Monday, I had nothing on
my schedule Friday afternoon, so I called a friend and we set off on
a trip to Home Depot. While our trip was delayed by a series of off-schedule
buses (we ultimately had to take a cab down to the store), we arrived
at a reasonable hour and set to work. We concluded that I had included
more than enough structural support and in the interest of money and the
quantity of wood we could carry back on the bus, we would eliminate the
horizontal supports I had planned for in the original specifications
for the platform to hold the panel up. We purchased 30' of 14 gauge wire
(which was the size Sundance recommended I buy) in red and black, electrical
tape to seal the ends, screws to fasten everything together, and all
lumber I would need for the platform. In the interest of stability, we
purchased concrete screws to anchor the platform into the concrete of
the balcony. As my friend was having the wire cut for us, I went over
to the tool rental center. At home, I would have had easy access to a
power drill, but at college, I had nothing of the sort, so I would need
to rent one. Unfortunately, the tool center could not locate its power
drill when I was there, they knew another department in the store had
borrowed it but couldn't track it down for me. Instead, I took the number
of the store and promised I would call them in the morning, hopefully
by then they had located it. While it meant an extra trip to the store,
at least access to the CCTA buses was free thanks to UVM. After waiting
another twenty five minutes for a bus, we loaded our purchases on the
bus and rode back to UVM. Later in the night, I received a notification
of shipment e-mail from UPS - at last the equipment was on its way.

The
Drill
The next morning I called Home Depot and they confirmed
they had the drill ready for me. I coordinated the bus schedules and
left around 12:20, arriving at the store slightly before one. I had to
return the concrete anchors (they were too short for my needs) and purchase
some forgotten supplies (a concrete drill bit, a screw driver bit, the
correct size concrete anchors). After checking out those items, I headed
to tool rental, where they told me they had the drill I needed but they
had just lent it out in store - it would be back in twenty minutes, the
tool rental staff assured me. Twenty minutes turned into an hour and
twenty minutes and after they combed the store for the machine, they
still could not locate it. They took my number and promised to call me
when it showed up. All this, however, caused me to miss my bus, so I
sat at the bus stop for forty minutes until a bus arrived. I took the
bus back, and was just about to arrive at my destination, when my phone
rang. It was Home Depot, they had located the drill. Not a problem, I
thought, I'll just ride this bus back to the store. However, the bus
promptly went out of service after it reached my stop, as the driver
had a lunch break. The next bus wouldn't be for an hour. I was at a shopping
mall, so I spent some time walking around, and then decided to run back
to my room (about 1/4 to 1/2 mile away) and get a book and my iPod so
I'd have something to do while waiting for the return bus. I did this,
made the bus out to the store, retrieved the drill (the tool rental people
were very appologetic, and I had no ill feelings towards them, as I was
just happy I had the drill) and waited half an hour for the return bus.

The
Platform Upon returning, I immediately set to work building the
platform. The night before, I had marked all the screw locations for
the wood. Now I just needed to align the support pieces and screw them
down to the platform. This wasn't too hard a task, all it took was some
precision and careful measuring.

Monday I awoke Monday morning to the perfect weather for installing
a solar panel. It was sunny, with no clouds in the sky, 79 degrees, warm,
but not too hot. I checked UPS tracking - the packages were on the truck
and scheduled to be delivered.
|
| |
|
|
|
|
|
|
|
|
| |
|
|
|
|
|

I spotted the UPS truck on the
way out to class. Sure enough, when I checked the tracking entry before
class began, the package had been delivered. But wait - there were two
packages. The battery in one and everything else in the other. The other
one still showed "out for delivery." After class, I went down to the mail
room in our building, and looked in my box - there was no package slip.
I explained that I had a package waiting for me at the desk, and the clerk
suggested that since I didn't have a package slip it was probably still
at the UPS facility. It was not, I insisted, it was scanned as having arrived.
The clerk went back to look, and, sure enough it was there.
I carried the package to my room but wondered - what about the other
box? I was holding the battery (I could tell by the size and the weight).
When I arrived at my room, I called UPS. After waiting on hold for 12 minutes,
UPS informed me that the package was scheduled to be delivered today, and
it most definitely would. The UPS representative suggested that there might
have been a large load today, and it might be coming on a second truck.
A reasonable enough explanation, but I was still worried.
Since the solar panel wasn't in yet, I decided that I'd at least get
the wiring done. I needed to run the wires I had bought from the balcony
to my window. There was a small opening in the bottom of the window which
the wires fit through, fortunately. How would I get them in my window?
The answer came in the form of a wooden pole that I found in the closet
of the suite. I jammed it in the window, so it stuck out like a flagpole,
and then tossed the bundles of wires over it. Then, I went into my room
and pulled the wiring through. |
| |

The wire I purchased at Home Depot.
|
|
|

Before I threw the wire to my room, I secured it to the railing of the
balcony.

|
|
|

Success! After a few tries and an adjustment of the pole, I was able
to snag both wires.

|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|

The windows in my room just happened to have a convenient
space for threading wires. Had I not had this gap, I likely would have had
a much more difficult job. The window closes nicely around the wires, also. |

With the wiring in place, I grabbed
a bus back to Home Depot to return the rented power drill. I was hoping
by the time I returned UPS had arrived. They hadn't. There was no package
slip in my mailbox, but I stopped at the desk anyway. I explained my situation
to the clerk and asked if UPS ever made more than one delivery per day.
In her memory, they never had, which was what I thought. Since I still
couldn't rule out mail clerk error (assuming UPS just forgot to scan the
box as delivered) so as she was talking my eyes were glancing behind her,
scanning the mail room for any hint of the box. I couldn't find anything
obvious.
I decided to head over to the library to write an essay I had due the
next day, so that when the solar panel arrived later, I would have time
to set it up. Given my schedule for the rest of the week, I really wouldn't
have time to set the panel up - I wanted to get it done today.
At 4:30, there was still no sign of UPS. I called them again, and explain
that I needed to have the package today. I would even be willing to go
to their facility (just beyond the Home Depot I had purchased all my equipment
at) and pick up the panel if necessary. They took my name and number and
told me someone at the Burlington UPS depot would give me a call within
the hour.
Sure enough, forty five minutes later, my phone rang. The UPS representative
I spoke to said he had e-mailed the driver and that he had the package.
He wanted to know if I could meet him at the UPS Drop Box outside my building
at 6:35, which was the time he usually came by to empty it. I told UPS
I'd be glad to, thanked them for the time they spent locating the package,
and checked the time. It was 5:35. I passed the time working on this site
and at 6:25 went out to stand guard at the UPS Drop Box.
So much for the perfect solar day: the sun was setting as I left my
building, but I was glad that I would at least be getting my equipment.
The UPS truck showed up at exactly 6:35, the driver gave me the package
and appologized, saying it slid to the back of the truck in the morning
and he had not seen it. I told it was no big deal, as long as I had it
now, thanked him for bringing it by and headed back towards my building. |

As I tried to locate the panel, my frustration became evident in my
white board scribbling.

Wiring
the Panel, Outside
I unpacked
everything from the box, which included the solar panel, the charge
controller, the voltmeter and the inverter. Since
the wiring to my room was already done, all I needed to do was place the
solar panel on its mount and connect it's wiring to the wiring running
to my room. This was a fairly simply procedure that simply involved
twisting
the wires together then wrapping them with enough electrical tape to insulate
them from each other and the elements. Ultimately, I would secure them
to the mount underneath the solar panel, to provide the connections
with the
most amount of protection possible. Ultimately, I may use some type of
sealer to seal the connection, but for now I'll see how it holds up.

The
Wrench Sundance had provided a very nice, easy to use instruction
sheet with the panel and as I hauled the contents of the package to my room,
I pulled out th sheet. The second instruction was "Locate the
charge controller. Using o-ring connectors, connect the -negative wire
(black) to
the -negative side of the battery (black). Do not fully tighten yet." I
suddenly realized I had nothing to tighten/loosen the battery terminals
with. At
home, setting up the same system would have taken a fraction of the time,
having access to the power and hand tools I needed. The challenge was not
necessarily constructing the system itself, but rather, the environment
I was constructing
it in. It now being 7:00 PM, my calls to local hardware stores all went unanswered.
Home Depot was open till 10, but the buses to the store had already stopped
running. I suddenly had an idea. Radio Shack was open till 9:30 and their
web site indicated they had just the wrench I needed for $3. I checked the
bus schedules and decided to take the 8:20 bus after dinner. I finished dinner at 7:40 and decided to walk to the Mall
instead. As soon as I began, I noticed a side street that seemed like an
excellent shortcut to the mall. After 15 minutes of walking, however, I realized
my error, there was a four lane highway between the mall and I. I briefly
considered trying to run across it, but there was a tremendous amount of
foliage between the highway and I, in addition to the fact that running across
an interstate highway is not exactly a bright idea. I found myself in the
pitch black standing in the middle of a farm field. I was somehow able to
navigate my way back to UVM, and as soon as I approached the main road to the
mall, I watched as the 8:20 bus wailed past. It would have been shorter
to just have waited for the bus. To make a long story short, I walked to Radio Shack, then
grabbed the bus back to my room.
Wiring the rest of the system Back in my room, I unpacked the wrench and went to work.
I removed the lugs on the battery, then connected the charge controller
as instructed. The controller was then connected to the solar panel wiring
I had snaked in my room earlier in the afternoon. From there, I connected
wiring from the battery to the voltmeter, and also to a fuse and the DC adaptor
that would allow me to connect my devices to be powered by the battery. After
a little over an hours work, the entire system was wired and online, and I anxiously
checked the weather report for the following day.
