The Panels Are Up!

I, Andrew, am delighted to report that all of the solar panels for phase two of our project are mounted!  At the moment, the crew is burying the conduit that will carry the power from the inverter (which will be mounted on one of the posts holding up the panels) to our building.  We are looking forward to finishing up the installation and being able to make some power!

Here you can see phase two:

And here you can see both phases one (closest) and two (in the background):

Installation, continued...

Now that the posts are all in place for phase two of our solar array, we are ready for concrete!  The truck came yesterday, and the crew was busy pumping concrete, making sure that the posts stayed level as the concrete rushed into the holes.  After one truckload was poured, all but three post holes were filled, so we had another smaller load of concrete come down to the site today to fill the remaining holes.  With all of the posts now set in concrete, the crew is setting up the mounting hardware, and beginning to mount the panels!  We hope to have all the panels mounted by the end of the day tomorrow (Friday).  Then we can begin the work of wiring the panels to the inverter, and then into our electrical system.

The posts are set, leveled, and ready for panels!

The posts are secured in 8 feet of concrete.  These puppies aren't going anywhere...

Installation for Dummies

This week, we've been taking advantage of the somewhat drier weather to install our antenna test load (also known as a "dummy load").  The real challenge is figuring out how to set up rigging to carefully pick up and balance the equipment while carrying it out to its designated place in the switch matrix.  After a relatively short period of trial and error, we were able to successfully balance the test load, pick it up, carry it up to the antenna field and drop it into place.

The next step was picking up the chiller and carefully setting it on the concrete footings we poured.

And there you have it!  Our test load and chiller are in their proper place. (The test load is under the tarp.) All that remains is hooking up the plumbing and the electrical/control wiring.

The Digging is Complete

Finally... the time has come when the contractor was able to get the auger to the site where we are putting the next set of solar panels.   Phase 2 underway!

It was still quite muddy, the auger got stuck once getting it to the post holes.  But eventually success.
And just in time.  About 10 minutes after the holes were completed the sky opened up and we had torrential rains for half an hour.   The thing to notice in these pictures is The Sky!

After the rain shower they were able to get all the posts in place.  Weather permitting the concrete will be poured Wednesday (tomorrow).

Arrival of the Panels!

On Thursday morning, the long-awaited panels arrived at the site!  There was a miscommunication between the shipper and the freight forwarder which resulted in us thinking that the panels were supposed to arrive in port last week.  But after many phone calls between Mike and the freight forwarder's dispatcher, we figured out that the next phase of solar panels was arriving a week later than we had anticipated.  So two flatbed trucks carrying our precious merchandise were a welcome sight at the office down here in Merizo!

Upon the arrival of the trucks, we promptly fired up our not-so-trusty forklift and got to work unloading the panels, mounting hardware, and inverter from the first flatbed with relative ease.  Once we unloaded the first truck, the second truck showed up with the posts and rails used for mounting the panels.  It was at this point where Jim, pushing the limits of the forklift's operating capabilities, wandered off the straight and narrow and wound up stuck in a rut along the side of the road.  Luckily, Paul came to the rescue and pulled him out with the backhoe.

After that fiasco, we unloaded the posts and rails from the second flatbed.  This was a bit trickier because of the length of the load we were picking up with the forklift.  We had to pay careful attention to how well the load was balanced before picking it up from the truck.

Once all the equipment was unloaded, we put the panels, inverter and mounting hardware into storage in the barn, and left the posts and rails out so they will be accessible when the installation begins tomorrow!  Looking at these pictures, you can see that it is now rainy season here on Guam, so we are racing to get these panels set up before the weather gets much worse.  Please pray that we can get the panels installed before the end of next week!

Phase Two Has Begun!

Since phase one of our solar panel project was implemented almost a year ago, we have produced 39.6 MWh of energy!  This translates to roughly $13,000 in energy savings over the past year.  Our first phase has the capacity to produce 23 kW of power, but on Guam, we are permitted 100 kW of capacity for a grid-tie system.  Therefore, we are looking to add second and third phases of panels to utilize this renewable source of energy and further reduce our energy bills.  The addition of a second phase will bring our total capacity to 43 kW.

Phases 2 & 3 will go on the slope behind our building.

Early on Monday morning, workers from Kindo Electric here on Guam showed up at the site to begin work on the installation of phase two of our solar array.  Unlike the first solar array, this phase will go on the slope behind the transmitter hall (as shown in the figure above).  Over the period of two mornings, the workers set the layout and spacing for the panels, dug the postholes (shown below), and dug a trench from the location of the panels to the back of the building, where the panels will be tied into our electrical system.  All that remains is to install the posts, mount the panels, install the inverter and complete the electrical hookup!  We are hoping to have this work done before the end of the month.

Arrival of the Dummy Load

Today, the long-awaited dummy load arrived at the transmitter site in two installments!  We will use the new dummy load to test our transmitters without broadcasting radio waves over the air.  Through the process of sending many kilowatts of RF energy into the dummy load, a lot of heat is created.  Therefore, the dummy load comes with an enormous chiller and a big pump to move refrigerated water to cool off the dummy load.  This particular dummy load has a 300kW capacity, which is plenty for our purposes here at the site.

First, the chiller for the dummy load was loaded on to a flatbed truck and sent down to the site.  We fired up our trusty forklift, and Phil gracefully lifted the awkwardly long chiller off of the bed of the truck.  The driver then pulled the truck forward and out of the way so that Phil could guide the chiller and set it down in its resting place on the covered concrete pad at the back of our building.

After lunch, the moving truck showed up again with the actual dummy load.  Although it is smaller in size, the dummy load proved more difficult to move than the chiller.  We needed to rotate the dummy load on the flatbed before we could pick it up with the forklift.  Once we did that, we set it down inside the shop at the back end of the building.

The next step will be to build a structure for the dummy load to reside in where it will be protected from the elements, and to move the chiller to its resting place on three concrete footers that we poured next to the retaining wall for the antenna switch matrix.
