Solar Power on the Teardrop Trail

In an earlier post, we described a simple solar system for the our teardrop. With only a 15-watt capacity, we needed to upgrade and did so last year. We’ve gotten some questions about our solar power installation on the teardrop, and I wanted to share what we’ve done. This a work in progress, but during our recent Big Bend trip, we never hooked the trailer up to shore power (aka 120 volt hookups) and used solar power almost exclusively. It’s important to state our goals however, we didn’t intend to replace shore power. Instead, we wanted to extend the practical range of our trailer, making it possible to use primitive campsites for days at a time. This is where solar power can really shine (pun intended) on a small trailer.

There are several elements to a solar system. At minimum, a solar panel, a storage battery and some kind of charge controller are needed. Additions include 120/240-volt capabilities like battery chargers and inverters. Our system is almost exclusively 12-volt. With it we run lighting and have the ability to charge multiple devices such as smart phones, tablets, a laptop and digital cameras. We even have the ability to run a few high current 12-volt appliances like an electric tea kettle intermittently. Our trailer has a 7500 BTU air conditioner (this is Texas after all), but that must be run on shore power.

Broadly speaking, there are two types of charge controllers: Maximum Power Point Transfer (MPPT) and Pulse Width Modulation (PWM). Both have their advantages, but a PWM controller won in cost and efficiency for our particular application: hot, sunny climates and systems of 170 watts or less.  An article with a more complete comparison may help with your decision.

Here’s what we ended up with:

  • Renogy® 100-Watt Monocrystalline Bendable Solar Panel (update: no longer available, but this panel is similar)
  • Renogy® 10-Amp PWM Solar Charge Controller (update: no longer available, but this controller is similar)
  • Interstate Group 27 Marine Deep Cycle/Starting Battery (available from Costco)
  • Jensen JMP-800 75-Watt Power Inverter (plugs into a 12 volt outlet for occasional use)

Fortunately, our trailer was built with dual wiring: 12 and 120-volt. There is 120-volt power in both the galley and interior, and a 12-volt outlet is available in the interior. I added a 12-volt feed into the interior cabinets to power a Ten-Tec Triton II amateur radio. Most of the installation work involved mounting the solar panel on the trailer’s roof. The charge controller was mounted in the galley storage adjacent to the battery. The trailer was already equipped with a small charger, and it charges the battery when we’re hooked up to shore power. The solar panel can be removed from the roof and located away from the trailer using an extension cord. This way, we can park the trailer in a shady spot while the panel is located in the sun. The photos show the mounting screw installation process.

The trailer came with 12-volt automotive light fixtures and incandescent bulbs.

These were replaced with LEDs resulting in a 75% power savings. As I mentioned, it is a work in progress, and I would like to add a second panel. There’s room on the roof, and that would double our capacity.

More Storage – A Trailer Tongue Box

Jim, May 17:

During the Big Bend trip, I started to think about refining our trailer and realized that storing jacks and other trailer equipment in the galley complicated our setup. A second storage area would make the galley more convenient and allow Marilyn to start our evening meal while I was setting up camp. I had seen boxes that mount on a trailer tongue, and thought that might be the answer. They aren’t hard to find, and I soon had one on order. Made by Better Built, and 34-inches by 19-inches and 18-inches high, it looked like it would just fit on our teardrop’s small tongue.

In hand a few days later, it looked great and didn’t weigh much — welded aluminum construction with a locking latch and power-assisted top hatch. Our trailer has a single rail for the tongue however, and it looked like the box was better suited to trailers with a “y” front hitch. Mounting the soft aluminum box on a single rail seemed like a problem — the first time it was leaned upon, it would bend. I decided to get some help from my friends at Vintage Motor to make a stout steel mount. Jason and I quickly decided  to cradle the front and back bottom edges with 1 1/2-inch angle iron. These would be welded to other angle iron and attached to the 2 by 3-inch trailer tongue with bolts.

We set to work. After measuring the front and back box edge, Jason cut 16 and 34-inch pieces of 1 1/2-inch angle iron on a chop saw. By placing them under the front and back edge, we were able to mark the precise size and angle using a sharpie. Using these marks, he was able to trim the rails with a pneumatic cut-off tool, and round the rough edges with an angle grinder.

Next, we cut brackets and holes and drilled them to accept the tongue bolts. They were then welded to the rails. There was one bracket per rail, and they were placed so that the rails would be centered on the trailer tongue with a bracket on each side. Finally we drilled four holes on the long rail, and two holes on the short one to mount the box.

Rails and brackets complete, it was time for a test fit. Everything seemed to work, so I set about drilling bolt holes into the trailer tongue. This is very tough steel, and it took awhile — even with the help of my grandad’s 1/2-inch drill. Now we could bolt the rails on, and set the box into them. Last, we drilled holes from the bottom, through the rails, and into the box. It was secured with six bolts as well. We’d had to “fudge” the fit to straighten to box and allow for lid clearance with the trailer, so the front rail was a little off-center. A trip back to the shop to adjust it’s length, and we were ready for paint.

Now painted, it was time for the final installation. To protect the bottom from being dented, I’ll cut a piece of plywood to fit the inside. The box size seems proportional to the trailer — a lucky break. I was also pleased to see that the diamond plate on the trailer matches the box, both in pattern and rising to about the same height as the diamond plate on the trailer. Looks like a custom fit!

The Storm

Jim, June 24:

We’re tooling along in Kansas, and travel was filled with the joys of using the old atlas and The Girl for navigation. Paper meets high tech. Hot, Sunny and miles of flat, straight road ahead. The only thing to break up the monotony was a construction zone with very aggressive rumble strips to slow down the traffic. Normally we wouldn’t have noticed. But then, passing cars and trucks began waving and gesturing to us. “Oh, look, more teardrop fans!”, “Isn’t it fun that we seem to be attracting attention with our cool trailer!?”

Then Marilyn looked into her rear view mirror and noticed that the galley hatch was up. Hmmm. Perhaps we’re not as cool as we thought. Everyone was trying to tell us about the lid. *quiet chagrin*. We stopped and corrected the problem, and it became her job to periodically check on the galley hatch.

I’ve been through Kansas many times, and it’s normally quite dull, so I wasn’t expecting what I saw next. Out my side window, was one of the blackest skies I’ve seen recently with the clear indication of a wall cloud. Severe Weather! In other circumstances, I might have just tried to outrun the coming storm, but we were towing a small, light-weight trailer. On it’s first trip. Although it looks airworthy, I didn’t really want to try it. We needed shelter! Plains, Kansas wasn’t too far, and we could see a large grain elevator. We drove into town, headed straight for the elevator, and hunkered down. We had enough cell service to use our iPhones, and Dark Skies and Weather Bug gave us radar views of the storm. We spent the next hour in torrents of rain and blustery winds, but fortunately nothing worse.

We decided we could make McPherson, Kansas that night, and after a near rain-out the night before, and a near miss by a violent storm, we were feeling a little moist and beleaguered. The McPherson Holiday Inn would be just fine.

Jim, June 7 – June 21:

I wanted to add my ham radio and a solar power system and we were about 2 weeks from departure. The TenTec Triton II radio was mounted in an interior cabinet and connected to the antenna ball mount. A piece of 3″ PVC tubing, mounted outside in the rear, provided storage for the whip antennas and their coils. A weekend shopping trip to Costco yielded a 15 watt solar panel and charge controller that I connected to the existing trailer 12 volt system. Although we were likely to have 120 volt “shore power” when camping, the solar panel could provide power if we decided to set up camp in a remote area. Time to pack!

Jim:

We discussed how much fun it would be to go to the Red Power Round Up in June in our very own Teardrop Trailer. There were a couple of problems however. I certainly wasn’t going to have time to build one in the available time and commercial models are quite expensive. I wasn’t sure about spending so much money just to see if we liked it. The handmade model we saw at one of the RV dealers was closer to what we wanted but still a little pricey. I looked all over the Internet, but it was the same story everywhere — teardrop trailers are a boutique item and command premium prices. Perhaps a used one would do.

Craig’s List was the next stop. It’s easy to search a town or geographic region — perfect since shipping a trailer across country isn’t easy. There were always a few teardrops listed, but nothing that really spoke to me. Then I noticed a listing from EZ-Toad Trailers. There was one available, in the right price range, but with no galley. A phone call confirmed a teardrop with a galley could be ready in time and modifications could be made to suit our preferences. I thought about it for a day or two, and called Don (the builder) back to complete the deal. A teardrop in four to six weeks!

Waiting was difficult but Don sent pictures every couple of weeks as the build progressed. We would drive to Fort Worth on June 1st to pick it up. We were now the proud owners of a custom-built teardrop trailer!
