Time to Hang it Up!

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 you have a Patek Phillipe Grand Complications Celestial model, you probably have your people work on your solar system. I […]

Why not?

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 others with a little more room and a bigger budget are also having fun with their systems. I am jealous.For […]

Waiting my turn in Nawlins

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 on the boat. Are you afraid of “B” panels? I’m not. I put six of them on my solar-powered expedition […]

Solar everything, even the honey dipper!

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 up by the motor maker. Or maybe they can actually get that rig up on a plane, for speedy service. […]

Inquiring Minds Want to Know!

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. Short circuit current of a shiny new panel should be around 8 amps. Open circuit voltage should be 44V. In […]

Here’s a handy idea for after a storm

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, either NiMH or NiCd. You can put regular alkaline AA or AAA batteries in them if you want them to […]

Battery Connections Illustrated

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 is hard to see the polarity, should I need to reconnect anything.  You can see where I marked the 2 […]

In defense of crappy free solar roof tiles

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 panels for his cabin power upgrade and 300 roof tiles at the old Miami Gardens store.  I know about the […]

You could void your warranty doing this stuff

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 get a hole. I started with a Suntech STP280 that got hit with a tractor.  Yup, that’s a busted one!  The […]

Here we go again. Hurricane Michael is projected to hit our vicinity as a Cat 3 storm. Get ready everybody!

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 dumb, they just don’t know any better.  At my house, the ceiling fans have a slight buzz from the inverter […]
