I enjoy sending and receiving low powered Morse code (called “QRP” CW) over the amateur radio bands. I power most of my equipment with batteries that I charge in my backyard off a 40 Watt solar panel. Since Colorado receives a lot of sunshine, throughout the year, I almost never have any difficulty charging batteries when it’s convenient for me. Most of the time, especially for these old/used gel cell batteries I do not use a charge controller* and rely on simple “alligator” clip leads for my connections. When time and money permit I hope to power most of my home off solar. However, as it is now, we subscribe to Xcel Energy’s “Wind Source” to power our entire home at this time. It’s something we’ve subscribed to for many years but believe it’ll be more fun, in the future, to create our own power!
*Although I don’t often use a charge controller I do, at times, insert a diode into the charging circuit to keep the batteries from discharging through the panel if the sunlight gets blocked by heavy cloud cover or I forget and nightfall occurs, etc. However, I even try to avoid using the diode, when I know I’m going to be home most of the day, since it creates a little bit of a voltage drop in the charging circuit…
Here’s a YouTube video of my $20 lead-acid “Lawn and Garden” battery being solar charged: http://www.youtube.com/watch?v=tmRnV3DooN0
Here is the YouTube video of my amateur radio station that’s powered by these batteries at the time of this video:

You gotta love Trump’s sense of humor
When I first heard about Donald Trump’s solar-powered border wall, I really thought it was a joke.
Question: “So how did Trump sell the idea of a border wall to ‘progressives’?” Answer: “By covering the wall with solar panels.”
But it turns out it’s no joke. It’s just an example of Trump’s political instincts as well as his entrepreneurial business acumen as one of the premier builders in the world. Think about it. He made a campaign promise to build the border wall. It may have been the No. 1 reason he was elected president. He pledged that Mexico would pay for it. We all collectively scratched our heads wondering how he would accomplish that. And here it is! He’s going to produce electricity with the border wall and, no doubt, sell it to Mexico for many decades to come. Genius! Who could have guessed? And who would oppose the idea? After all, this would be one of the biggest experiments in the development and production of solar power in the history of the world. And who are the biggest advocates of solar power? The same people who are adamantly opposed to the border wall project. But he didn’t pitch it to Democrats. He pitched it to Republicans who control Congress. The plan was actually the brainchild of Thomas Gleason, managing partner of Gleason Partners LLC, a Las Vegas-based architecture firm that submitted a proposal to the Department of Homeland Security that included solar panels. He had been batting around the idea of building a solar-paneled wall along the U.S.-Mexico border “for months.” Then he directed his company to come up with a design and “get it in front” of the president after the DHS requested proposals. Trump recognized the political and financial potential. The wall would generate enough power to pay for its construction in less than 20 years, Gleason believes. But he cautioned that numerous variables – the Mexican border is far from a straight line and light intensity changes from month-to-month – could complicate his calculations. He said his firm hasn’t received the go-ahead from the federal government to conduct a full evaluation. Gleason said his estimate is predicated on the cost of manufacturing solar panels decreasing over time. The price of installing solar panels has dropped from around $8 per watt in 2009 to $1.50 per watt in 2016, according to the Solar Energy Industries Association. Gleason said he believes that farmers on both sides of the border would appreciate the wall, as the energy output would create a “microgrid” that could provide cheap power to remote areas on the border underserved by energy utilities. “We’d be our own utility,” Gleason said, though he said third-party contractors would need to actively manage the wall, per the DHS request. He said the cheap, renewable electricity produced by the wall should “mitigate” political resistance over time, and increase property values along the border. “Our intent is to offer a realistic, no-nonsense design for the wall that pays for itself that will make everybody happy, including our president,” Gleason said. In the pitch process this spring, at least two companies proposed designs that included solar panels. After being rebuffed by Congress for money to build any wall in fiscal year 2017, the administration has asked appropriators for $1.6 billion to build 74 miles in 2018, according to DHS: 32 miles of wall in the Rio Grande Valley, 28 miles for levee wall in the Rio Grande Valley and 14 miles of replacement for secondary fencing in San Diego. Border Patrol agents love the idea of a transparent wall so they can see what’s happening on the other side. That’s another reason the “solar wall” could serve two important purposes. You gotta love this guy. Build the wall!
