Just a letter to John that somehow got posted here! I’m glad to hear you are back in the water. Sounds great. Somehow I didn’t get to the water all year. Now it is too cold to stay out on the boat overnight.I like pelicans, too, from a distance. It is funny how they almost […]

When my grandfather came to this country over 100 years ago, he worked his way around the US and Canada learning English and looking for just the right spot to establish a farm. About 1920, or so, he found the right spot on the shore of Lake Okeechobee, in Palm Beach County, Florida. It was

Going through my morning email newsletters, I came across a press release from a company called LONGi, announcing a new record of solar module output efficiency of 20.41 percent! The exclamation mark was theirs, because another tenth of a percent doesn’t get me all that excited. Last week some outfit announced their record output of

I have been rambling about backup power and it is time to touch on the batteries and other topics. My advice on backup batteries is a little different than for solar systems. I advise that you get something that requires little or no maintenance. The reason for that is that you will probably lose interest

Continuing on the subject of a backup power supply for your house, I want to discuss the inverters a little more. There are things to look for and things to watch out for! I have owned lots of inverters, ranging from 150 watts to 12,000 watts. Some were high end and some were junk. I

Coming out of last weekend, the network news guy told us how many HUNDREDS of THOUSANDS of homes were without power in the wake of a big snowstorm, which included a lot of area where people were not accustomed to dealing with such. It looks like a little more of the same this weekend. Here

Remember when you were a kid and you always had to ask Mom or Dad permission before doing anything so you wouldn’t get your bottom smacked? Boy, you couldn’t wait to grow up so you could do anything you wanted to do! Then you grew up and found out you still had to ask permission

For some months, the wife has been grudgingly patient about the Trace 2524 in the living room. Why was there an inverter in the living room? I’ve been engaged in a multi-year evolution in my power system, so lots of new stuff has been coming in and out of service. In our Southern climate we

After playing phone tag the other day, John and I were having a conversation about all things solar and my Solar Shed phase 3 performance. He asked how well the modules were performing as these are all recycled salvage panels in the form of roof tiles. I replied that they are doing well, having seen

I looked for that article we were talking about, regarding fracturing cells for greater output. I found lots of articles on how fracturing can reduce output, but not the one for which I am looking. I did find a patent for manufacturing cracked cells to increase output. Patent for fracturing cells. Link Here are my

I started taking old radios apart as a very young kid, began my career in electronics at 16, was a licensed broadcast engineer at 19. That led to computers and all kinds of electronic gimcrack design. Having been making sparks for so many years it is easy to forget that some of the basic stuff

The other day we talked about series and parallel connections of batteries. You know, getting 24 volts using four 6 volt batteries in SERIES and getting lots of amps at 24 volts by using 2 of those 24 volt strings (8 batteries total) in parallel. What about connecting your solar modules? Yes, it applies there,

Can you get too much solar power? Spend too much time on Pensacola Beach and you’ll think so, and have a red face to remind you. But, no, I am talking about photovoltaic power. In the case of grid tie, it has gotten to the point in some places that they are having to add

I want to talk about the Solar Lifestyle and what that means. Elsewhere, I have given links to the Home Power Magazine Archive. That is a treasure trove of information and each issue is a time capsule of where the state of things was at that time. Early on, solar panels were small and expensive.

Utility power began with a fight between AC and DC systems. Thomas Edison promoted DC distribution. His ex-employee Nikola Tesla, the real Tesla, came up with the AC system for George Westinghouse. Both sides advertised how dangerous the other way was! What a way to promote a new industry! Power stations were not the huge

Stan-the-Hermit called Friday, needing some bits and pieces to finally get his 24v solar power system running. He’s had his panels for well over a year, having accompanied me on my final run to John’s old Miami Gardens warehouse. They’ve been mounted for months. He left my place happy with an armload of switches, breakers,

I like wristwatches, especially ones with classic art deco styling. I quit wearing them when I had my hands in commercial radio transmitters a lot. Other people got away from wristwatches for a while, having their phone has an accurate timekeeper, but watches are making a comeback. They are becoming quite the investment, too. If

I figure anybody who has built a solar power system has good reason to take pride in their work. I know I am proud of mine, but now I am a little dismayed. My system is just a solar-roofed shed. It is practical and it works, which is fine, but now I have seen that

Is that a smile or did I just put my elbow down on a hot PV module? I’m catching some rays through the sliding module hatch of my solar expedition launch, Sun King. This is at New Orleans, home of the weirdest lock and drawbridge combination I have ever seen. 1620 watts of “B” panels

If you spend much time around boats you know that you can’t just flush overboard. The holding tank has to be pumped out on occasion. Now there is a solar-powered roving pump station. http://www.solardaily.com/reports/The_worlds_first_solar_electric_sewage_pump_out_boat_is_powered_by_Torqeedo__999.html In my opinion, they got this wrong. There is way too much motor on this thing, probably because it was set

Over the weekend we really went to extremes to show just how tough solar panels can be. Today we’ll tell you the results. We started with a Suntech STP280 that had been hit by a tractor. The frame was bent, wires were ripped loose, glass was shattered and many of the internal cells were broken.

You know those little solar sidewalk lights? You can put them outside during the day and bring them in at night. I wouldn’t read by one, but you can find your way around the house with it and it is safer than a candle. Most of these have a AA or AAA battery in them,

Elsewhere in the blog page is a post about battery safety. I have a couple of battery photos to illustrate what I was talking about the other day, easily making battery polarity easier to see.  The old 24v battery strings have decent cables, grease to seal out corrosion, but they are a bit dirty and it

John’s right, the quest for attractive and practical rooftop solar with these tiles was a flop.  Some of it was design flaw and some of it was improper installation.  I hope Mr. Elon Musk, who is marketing solar roofs, has investigated this matter lest his quest should fail as well.  Stan-the-Hermit poses with 10 conventional

It’s a beautiful, cool sunny day here in NW Florida and you’re right, John, you can knock a hole in a solar panel and it’ll still work.  Just don’t try it with a hammer, because there is a tough plastic layer under that glass and another on the backside.  You need to be forceful to

Hi John, John, you live in a glass tower, but out in the neighborhoods you can hear the generators buzzing after a hurricane has taken out the lights.  200 watts for the fridge and 50 watts for a ceiling fan and they’ve got those darn 3500 watt generators blasting away at 3600rpm.  Dumb.  Well, maybe not
