Some people build their own solar power systems. Some people pick up the phone and then write a check for theirs. It’s ok, either way, but I advise that you at least have a basic understanding of how things work. If you have to ask why, I can give you a recent example from my

When it is raining buckets and the wind is howling, it is very comforting to have the lights stay on when the power lines go down.

You may have noticed that it is political season. What have the politicians personally done for solar? Jimmy Carter put solar-thermal panels on the White House roof. They came down the next time the house was reroofed, though they were still working. One is in the Smithsonian and another is in a science museum in

Oh, will they ever come up with the perfect battery? Super capacity? Super cheap? I’ve met one guy who has learned to adjust his pace to make it from Pensacola to Miami in a Tesla. Maybe adopting a more relaxed pace would be good for most folks! Solar Jorge, down in the Keys, likes the
If a terminal is broken or melted on a battery, you may be able to save it with a simple fix.
I recently had to burrow into the entrails of my new 21 year old truck’s transmission. It is sort of a rite of passage with the old Dodges. Specifications for putting the various pieces back together are very specific. I remember what my little brother did to his Plymouth’s transmission 45 years ago and I
Every now and then you need to tidy up a bit. I’m bad about that sort of thing. I needed to take a truckload of batteries up to the recycler in Atlanta, but the Chevy just won’t carry enough. Then I inherited, sort of, a Ram 2500, which can carry an additional ton without any

It makes me mad to see that people die after the storm. You buy a generator to keep the lights and fridge on, but the thing can kill you. Here are some thoughts. First of all, have a battery backup system in place. This can be a building block for a future solar power system

This was in the morning newsletter from the American Solar Energy Society. “A household rooftop solar panel system can reduce pollution by 100 tons of carbon dioxide (CO2) in its lifetime—and this includes the energy it took to manufacture the solar panels. Solar panels can improve future air quality for humans as well as the
When adding an upgrade to your solar power system, consider what other components may need to be upgraded as well.

Have you connected a battery, a charge controller or an inverter and had rapidly charging capacitors make a loud pop and maybe even a welding arc that messes up a bolt? That can be really annoying and it can be dangerous, too. I have never had it blow up a battery but I have had

A widow has asked me to dismantle her 4 year old 10kw PV system. It isn’t that she didn’t like solar power, but she has to sell the house now and mortgage inspectors are brutally thorough and her husband had overlooked the business of permits when he installed the system. In the process of going

I have been observing the performance differences of my west wall array and my conventional south arrays. Arrays still pick up a lot of power under cloudy conditions, but the south arrays are doing better. I think I know why. The current situation is that the west wall will do pretty well with direct afternoon
Have you seen the $7 solar modules on the Sun Electronics web site? They are 70 watts, so that’s only a dime apiece for a whole watt! Can they be any good??? I admit it, I am a tightwad and bargain hunter. I didn’t need 50 more solar modules, but I saw where John was

There are good deals. There are bad deals. There are scoundrels who will try to tell you their bad deal is good. If you don’t want to deal with all the razzle dazzle in solar power systems, do it yourself and you will know exactly what you have.

It is a weather-tight box that combines the outputs of a number of solar panels before sending the power to the next level of equipment. It can be simple or very elaborate. I was recently looking at them for a project I have. Solar panels are sometimes used as singles in parallel or in multiple

A Cultural Resources Management (CRM) firm recently had a question about an old water-powered mill in our county. You don’t think much about water power in a state as flat as Florida, be we had lots of them. US 29, through Escambia County, could have been named “Industrial Boulevard” there were so many. The firm

Fuses offer cheap circuit protection, but there are some precautions you may need to take. The H-Bridge locked up on my inverter recently. It blew a fuse. It blew it with a lot of self assurance, too. There was no dilly-dallying. Never mind what an H-Bridge is, but in this case it can handle 1200
You know, the time when you do your preventive maintenance. Unless you have sealed AGM, Lithium or other such batteries you need to check the water at least once a month. Even if you do have sealed batteries, there are other things to check. Back to the water, this is a rehash, but in case

They keep changing the rules on grid tie. Avoid dual meters, special fees and changing deals by mixing your power with that from the power company, without backfeeding to the grid. Many years ago, a fellow came up with a gadget he called a synchronous inverter. Today we call it a grid tie inverter, and

And why would I want one? No, DIN does not equate to a cacophony. It means for German Institute for Standards, or National Standard, bearing in mind that Germans spell things differently than we gringos do. There’s all kinds of DIN stuff, so it isn’t just rails. DIN rail is a metal rail, usually aluminum

And Tropical Storm Cristobal is on the way. It looks to be heading to Louisiana, but Florida is getting the bulk of the rain. As far as storms go, this should be pretty mild, but you never know what tornadoes might pop up. Driving could be tough. Trees can fall on power lines. Hopefully, those
Ok, you know I like to talk about safety, often based on experience, so here is a quick one I bet you haven’t thought about. I am planning to try some of those 10 cent FS70 solar panels that Sun Electronics is selling and then write a review. I have actually used 4 of them

In it was a handout touting the cooperative’s dedication to service to its members. The coop power had been out for over 3 hours at that time, owing to a car vs. pole incident. A neighbor had power because I could hear the generator buzzing. I had power, too, but nobody could hear it. Back

Last week, during my morning coffee and internet infusion, I read of a very large solar power plant being planned for Bureau of Land Management (BLM) land in Nevada. Then, this morning, I read about a 6.5 earthquake in Nevada. Man, it’s always something going wrong, isn’t it? Then I heard Puerto Rico had one!

Reassessing capacity. I read online solar news journals every morning while the coffee soaks in. Most of it is grid stuff, but those guys are in it for the money and have the bucks to pay for the research, so I pay attention. I also paid attention when I lived very closely with my solar
Let’s build some cables I told you the other day I had reached the limits of what my homebrew 5500 watt inverter could do. I had a 10kw driver module to install, but it was bigger and was going to need some more cables. One night I switched the house to grid, ran a power
John tells of the glories of swimming with the fish in Miami’s bays. Then he tacks on something solar. It’ll be a while before I get back into the water, but I have some solar sea stories. I built an electric boat and it was great, but I couldn’t travel with it. I could easily

They are now making solar modules with power output in excess of 500 watts! Wow, that’s what I need for the Solar Yacht, instead of the 330s I have now. The thing is, you just can’t buy them, yet. The superest, duperest biggest and bestest go to the solar farms. Don’t worry, by the time
I chased one and it wasn’t what I thought it would be. A big part of living off grid or keeping the power bill down if you are on grid is efficiency. Try as you may to get everybody in the household to turn off unused lights or to not leave the fridge door open,
Sooner or later, you gotta do it, whether it is the clock, the smoke detector in the hall, the car or your solar power system. Oh? You have grid tie and don’t have to change the battery? We’ll talk about that, too. The batteries that I had on the main bank were in great shape,

Spare, extra or redundant, call it what you like, chances are you are going to need more. Oh, yeah, there’re fuses and connectors and such as that, but I’m talking about wire and cable, here. When I was a young broadcast engineer at WCOA, Pensacola, I engaged in a total rework of its broadcasting facility.
I wrote the material below quite a while back and it somehow fell through the cracks. I have since gone through a couple of variants of a Zero Export Grid Tie system, including a new one this past weekend…and the power company’s meter hasn’t budged since! Read this to get up to speed and there

We have some new buzzwords in our vocabulary and a new normal. Self-isolating and social distancing. Miami is kind of a hotspot in Florida, so John has the store closed so everyone can stay safe. Roberto is manning the phone, though, so if you need something you can still get it. The phone transfer mechanism

The homes of my grandparents were special places when I was a kid. Bro and I went by the former Collier house on a recent trip to Lake City, Florida. It was a sad sight. The big camphor tree, where Dad had his tree house is now just a stump. The yard is grown up.

Did you ever read, “A Tree Grows in Brooklyn?” I can’t remember if I ever did, but I know I had the book. If there is a tree there, I’m sure the dogs appreciate it. There probably isn’t much solar power on the neighborhood level in Brooklyn, so all is good. There are lots of

It has been in the 80s here for a week. When the nights were still dipping down low enough at night the house would stay cool enough. Not now. It is time to fire up the a/c. The solar-powered a/c. I have written about combining solar and a/c before. Go back in the blogs to

My brother and I drove across Florida from Pensacola to Lake City on business. It was good to put faces to the voices we knew from the phone calls. What we were not expecting to see were thousands of solar panels. The last few times I’ve been across Interstate 10, all you’d see of note

I don’t watch much TV, beyond the network evening news. I was in the kitchen eating when my ears perked up about something solar on 60 Minutes. Then I heard Rocky Mountain Institute mentioned.

Kris Kristofferson had a big hit with a song on that theme. Instead of moaning about why things had gone so wrong, though, he was wondering why good things had happened when he felt he didn’t deserve them. Well, things can go wrong in your solar power system, just like anything else, and you’ll have
You might thought I have forgotten poor ol’ Will. No, I have been busy and I think Will is now leaning toward grid tie. He has such a big load and the whole purpose of going solar was to save money when he retires. Grid tie can be a whole bunch cheaper than going off

Going through this morning’s online solar newsletters, I saw some new products that are on the way. This is not at all unusual, but a couple of these things made an impression. In solar modules, Trina is using bigger cells, but slicing them up and arranging them so you can get 500 watts from a

You know the old saying about one bad apple causing the whole basket full of them to go bad. The same thing applies to batteries. I am there, now, and so is Mark. Like me, Mark seems intrigued by the Simpliphi lithium batteries, but is also interested in getting a little more life out of

Stan called and he was happy. His old 12v system, pictured above, is really getting tired. It consists of nearly 50 mismatched modules and two windmills in parallel on a single overworked charge controller! His new 24v system is running, but only half-installed and there have been issues. After our little troubleshooting session the other
