Everyone starts somewhere... this is a brief story of my entry into the solar electric arena.
Back in 2002 my wife and I purchased a wonderful 22 acre block on an elevated site right on the edge of town, and started about the lengthy process of building our unusual earth-covered home. Trials and tribulations, red-tape, difficult neighbours, regulations, vandals etc all had a hand over the next few years.
Before we started building, we needed a reasonably secure site-shed to store things in, and decided to use a second-hand 40' shipping container. It became site-shed, storage shed and amongst other things - makeshift solar panel mount!
The earliest need for power was to run a small submersible pump to get water up to our new water tank. (105,000 litre concrete tank). The pump was a low flow pump, so needed to run for a long time. Running it off a generator was not practical, but solar was.
I purchased two 75W BP panels, at great expense (nearly $10/watt back then), and made a fairly rough but functional mount.
Here is is sitting atop the container. (The container is a "high-cube" - 9'6" high, with nothing to get hold of, so fairly safe against theft)
The frame was some old scrap steel, welded to form an "H" base. I drilled a large hole through the middle, to take some brass plumbing fittings that would hold the panels down, allow them to turn so I could align to the sun, and provide a water-tight entry into the container for the cables.
The frame was angle-adjustable for season by changing where the upright arms attached. It was pretty crude, but it worked.
The hinges at the bottom were (barely) adequate. Although supposedly galvanised, I think they were just stored in the same room as the zinc. They rusted and were not much good in surprisingly short time.
It wasn't much after the panels were set up than we started having problems with after-hours problems. So I put a small wireless IP camera in a weather-resistant enclosure and sat it discretely with the panels. It connected via wireless internet back to my office and home so I could keep an eye on things.
The solar panels charged a car battery stored in the container, with a PL20 charge controller. The PL20 ran the water pump when there was plenty of power available, and the battery kept the camera going the rest of the time.
A year later, it was time to move the panels. I'd set up a more permanent access point and the panels were more useful powering it (and a larger battery that wasn't getting so hot in summer - the container was over 65 degrees C inside)
The addiction clearly had begun. 2 panels were good. 4 panels must be better!
Another year on, and the panels finally made it to a proper mount rather than just sitting on the ground. This was a commercial tracker. It was cheap and flimsy, but it gave me a substantial increase in watt-hours per day, just by tracking. I also liked that the panels were finally off the ground.
And from these humble beginnings, I've grown to 3,500 watts of PV today.
