It’s Official: I’m Now a Ham (Part V)

One of the most interesting features  of Ham Radio is that its operators are expected to have access to alternative energy sources during times of regional or national emergency.

After all, what good is it to have a Ham Radio if you can’t use it when the power goes out?

For as many years as I can remember, I have been utterly fascinated by alternative energy sources. Capturing a tiny drop of the sun’s massive nuclear-reactive power (386 billion billion megaWatts) is a  fascinating concept.

After several tours of Mike Neal’s very own “Radio Shack,” and after receiving several helpful tutorials on this topic from Mr. Neal (and lots of specific guidance), I was ready to take the plunge.

My “solar project” started in earnest about a month ago when Mike sent me an email to let me know that Harbor Freight was having a sale on solar panels. This was the very set that Mike had at his house and he said it was “a good solar set-up for the money.”

With a $30 coupon (gifted to me from a fellow Ham), I got the $229 solar panels for $159. (The original price for the panels was $229, with a sale price of $189. The $30 coupon got me to $159.)

Because I’m highly allergic to crowds and shopping areas and loud noises and small children and fluorescent lights, I paid the extra six bucks to have the unit shipped directly to my house. It was well worth it.

It took about 12 hours to install the whole rig, and my oh my, it was a fun project. And watching those photovoltaic cells turn the sunlight into electricity is every bit as fascinating as I’d thought it would be.

If I were queen of the world (and it shouldn’t be long now), I’d recommend that every homeowner in America have a set of these on their roof. It was a great learning experience. And I’ve shared all the nitty-gritty details below.

To read more about my experiences with Ham Radio, check out Part I, Part II, Part III and Part IV of this series.

House shed

The little shed in our back yard is now electrified, thanks to these three solar panels on the roof. Each panel produces 15 watts, for a total of 45 watts.

I'm not sure why a corporation would adopt the name "THUNDERBOLT" for their solar products. Nonetheless, it's a sound value and seems to be a well-made product.

Solar panels

The solar panels were set on a 2x4 which was fastened with screws into the roof and painted flat black. The PVC frame was secured to the 2x4 with 3/4" metal pipe clamps. This will enables us to change the angle of the panels (for winter and summer) without any major disassembling.

This shot shows the panels and 2x4 more closely. In a mere 12 hours, the solar panels have already been assaulted by both birds (far left) and pine straw (bottom).

Thinking about how to get the leads into the little shed took some thinking.

Figuring out how to get the leads into the little shed took some thinking. In the end, I decided to drill a hole (3/4") through the 2x4 (and the roofing sheathing below). I reasoned that it'd be easier to patch a clean hole through a piece of lumber rather than trying to patch a hole in an irregular surface (such as an old roofing shingle).

solar

Using stretchy weatherproofing tape (which probably has a much better name), I bound those three wires (from the three solar panels) together and fed them through the hole into the shed's interior. I purposefully used a lot of tape so it would fill the 3/4" hole. For the tiny gaps that remained, I used a compound putty substance (again, don't know the name but it looks a lot like Silly Putty). Back in the day, a contractor friend told me it was called "Dum Dum" because you use it to patch a dumb mistake. However, I'd like to point out that it should be called "Smart Smart" in this particular application.

Inside,

Inside, the wires drop down from above and into the controller (right side on the shelf above the battery). From there, the wires go into the 12-volt deep cycle Marine battery. Another set of wires carries the power from the battery back to the inverter (left side on the shelf). The inverter turns the 12-volt current into 120 volts (for household use).

*

The

The controller that came with the solar panels is quite impressive. The digital display is large and easy to read, and reports on the battery power (12.4 volts shown here). For $159, it's a pretty fancy set-up and a darn good deal.

Another nice bonus that came with this set are these 12-volt LED lights. They do a good job of illuminating the dark corners of our little shed.

The inverter (shown above) was not included in the kit. This 750-watt inverter also came from Harbor Freight. I also got it on sale. As I recall, it was $69 on sale for  $49, and I found a $10 coupon. Final price $39.

Part of the problem I encountered whilst doing this project was, despite my reading and studying, I didn't understand a whole lot about how all these things work together. I asked Mike Neal, "What's the difference between a 200-watt inverter and a 750-watt inverter?" Fact is, a 200-watt inverter was whole lot cheaper. Mike explained, "Think of the battery as a bucket full of water. You can draw that water out with a swizzle stick or a milk-shake straw. The 200-watt inverter is a swizzle stick. The 750-watt inverter is a milk-shake straw."

*

The

The other helper in this project was my wonderful neighbor, Mike Mancini. I told him that I needed a deep-cycle marine battery and he got me a good deal on one at a local marine parts supply company. Plus, he gave me a ride out to the place and then hefted it out of his truck and out to my shed. This battery weighs about 50 pounds. I set it up on cinder blocks to make it easier to access, and I put the OSB down because I'd heard that batteries might discharge if placed directly atop masonry.

You may notice the fine-looking wires shown in the picture above (of the battery). I bought these booster cables at General Dollar Store and paid $5 for the whole affair. I then cut the wires off from the clips and used them for the controller-to-battery run and the battery-to-inverter run. It's 10-gauge stranded copper wire.

The last part of the project required anchoring the panels to the roof. In that the panels sit so high above the roof, they'll become a dandy sail in strong winds. Our solution was to tether the pvc frame to the opposite side of the shed. For the tether, I used 10-gauge stranded copper grounding wire. May seem like a waste, but I recently bought a spool of it to ground a couple antennas and masts and such. Seems I had about 400 feet left over from those other projects.

Hubby and I spent countless hours figuring out the correct angle for these panels. There were many factors such as the big old tall trees in our yard. After the "Solar System" was all set up, we were both AMAZED and pleased to see that it started charging immediately. What was so amazing? It was a dark, cold, gloomy overcast day. I can hardly wait to see how it does with a little sunlight!

*

Total cost of the entire project:

Solar Panels - $159 plus $6 shipping (and tax)

Interstate battery - $114

750-watt inverter - $39

Battery terminals - $8

Wiring - $5  (thanks Dollar General!)

Incidentals - about $20 (zip ties, pipe clamps, tape)

Total investment:  $351

Entertainment value: Endless!  :)

    O.K. you got me with the “queen of the world” line. Once I recovered from my laughter and the part about “and it shouldn’t be long now”, I was able to continue your post. Very interesting and lots of great pictures to explain it all. May you have many happy years of ham radio communication ahead!

    Hey Roe,

    Very entertaining reading (all 5 parts of being a Ham and Sears houses). I too am a Ham (technician class currently) however I have been an RF technician in Public Safety and Business two-way plus in Cellular for almost 20 years.

    Anyway just wanted to congratulate you and make a minor correction about HF waves. The frequencies may be lower however the wavelengths are actually longer hence higher meters for lower frequencies.

    Perhaps after I upgrade myself, I can try to DX you. 73s Pat Rhodes (O.C.A.R.C.- N.Y.)

    Hi Patrick,

    My electronics/RF knowledge is not too great, so I appreciate the correction. I find radio *fascinating* and the very idea that you can string a wire up in your yard and start listening to people in China and Japan and Australia is something close to miraculous.

    In your salutation, you said, “Hi Roe,” and I didn’t know if that was a misspelling or intentional. I have a handful of very close friends who call me “Roe” and I consider it a term of endearment, so I left it on your comment! :D

    I found your story while searching for Diamond X-300 antenna users and reviews.

    Been a ham for over forty six years and live in New Delhi, India.

    Occasionally visit US, where my son calls home in Bethesda/Md and actually operate both HF and VHF from there as India and US share a reciprocal licensing agreement.

    See you on air sometimes. Great website.
