Solar system balancing act

Life with a small solar system is a balancing act. We have lived 8+ years now with our small solar system, tweaking it, adding to it, improving it, trying to balance our system vs the power load. Of course we are running a small load most of the time, a couple of laptops, the wireless network for said laptops, a few lights, a 12 volt water pump, a small radio, and the fridge, THAT is what takes up the most power at any given time.

Our fridge is very efficient, it started out life as a small chest freezer, we use an external thermostat (originally designed to turn small chest freezers into kegeraters), we set the temp on refrigerator temps, when it detects the correct temp inside of the box, it cuts off the power to the unit, you can read more about that here. This last winter, we pushed the fridge outside to the front porch, which meant the box didn’t have to work as hard to keep the cold temps inside.

The biggest balancing act for us is the day length vs the outside temps. During the winter, we have shorter days, which means fewer hours in which to charge our solar system, but since the outside temps are cold, the fridge doesn’t have to run as often, sometimes not at all.

During the summer months, it’s warmer outside, making the fridge run more often, but with the longer day length, there are more hours of sun to charge our batteries, so all in all, it works out pretty well, as long as we pay attention to the upcoming weather and moderate our power useage as necessary.

With the warmer temps usually come our rainy season or monsoon season, a few months where we tend to get rain nearly everyday, having overcast skies also limits the amount of solar power we get, though our panels do get some charge even with clouds present, just not the full amount of charge as a sunny day.

I have some exciting news, I have been given the opportunity to review another battery desulfator, I did a review last year on the Whizbang Plus battery desulfator (part one and part two), they worked, but were small, you pretty much have to have one per battery, this other company’s claim to fame is their second generation battery desulfators are designed to work in off-grid situation on larger battery banks, there is much more to this system. I’ll keep you in the dark about it for now, but be looking in the next week or so, as soon as I get the desulfator, which is on its way here now, I’ll do a first impression review, hook it up and let you know what I think about it, I will say that it has many more features that are going to …

Mobile, stealthy, off-grid, vandweller

amv01
I think I got all the descriptive words covered there in the title, I am talking about Brian, also known as AdventureVanMan on YouTube. In his late 30s, single and hard working, he became disillusioned with life as he was living it and decided it was time to make a change.

Brian left his 2 bedroom apartment, sold most of his possessions, bought a cargo van and began living a life that makes him smile. He designed the inside of his cargo van to be simple, almost spartan, but it’s genius is useability and functionality. He lives in town, using a gym membership and friends & family for showering and other bathroom functions, so he doesn’t need a shower or major toilet system, he does have a backup toilet just in case, but doesn’t use it for the most part. All he really needs is a place to sleep and hang out when he’s not working.

Brian, being nowhere near retirement age, still works, so during the week, he stealth parks near where he works to save on fuel and time, on the weekends, he stays closer to the ocean in California, where he can catch a wave when he wants to, or just wake up to a beautiful sunrise glinting off the water.

I really appreciate his solar system setup, he put a lot of thought into it, utilizing the roof of his van to mount a RENOGY 100 Watt solar panel, he is able to tilt it to catch more sun, he uses two 6 volt deep cycle batteries wired together to make a 12 volt system, he uses a small inverter to power his laptop and other goodies, he also has some items hooked up directly to his batteries (12 volt goodies) so he isn’t losing power by converting from 12 volt to 110 watt. Some might deem to call Brian “homeless”, I don’t think that is the case, I feel like he made a reasonable and responsible decision to downsize and simplify his life, he wasn’t forced onto the streets, he chose to live this way.

A wonderful off-grid couple

stonecampThere are many off the grid tutorial videos about nearly anything having to do with off-grid life, there are a precious few about the people themselves, the why instead of the how. I enjoyed watching this video about Teddy and Kathy Carns and their off-grid life. Not only does it show some of the how, but it shows the why as well as their journey they are on. There is reality too, Kathy quit work to join Teddy living off-grid, but they soon discovered, much like us, that there needs to be some income coming in to pay for the things that you can’t barter for, things like taxes and such. I love it that it is Kathy who went back to work, in a field she obviously loves, this mirrors our life in so many ways, even down to the saving and dividing their trash into things that are biodegradable and those that are not, they don’t get rid of what isn’t biodegradable, they clean it and save it for future use.…

On demand water heater

waterheater1

There are a few needs, requirements for life, food, water, shelter, once those basic requirements are met, after that come the things that make life pleasant. When we first moved to our off-grid home, we lived in little more than a box (16X16) with few amenities. Most wouldn’t even consider living this way, but for me, for us it was paradise, living rough was just a small inconvenience, a small road bump on the road of our life.…

Motley Fool says bet on off-grid energy

Investor’s tip sheet, The Motley Fool – advises readers to “Keep an eye on [the off-gird] space, you might be “cutting the cord” sooner than you think. Which could turn the power industry on its head.”

There’s something going on in Kwigillingok, Alaska, says the Fool, It runs a microgrid, defined as a small closed power system that can operate independently, or in conjunction with, the larger power grid. Such small systems could be the future of power.…

Flower pot heater, does it work?

flower pot heater

The last couple of winters have been very hard for those of us living in the USA, the so called “polar vortexes” have come down from above, of course when I was growing up, these were referred to as a cold front, I suppose now they have to make it sound more newsworthy… at any rate, the winters are cold cold cold, many rely on grid power to keep their homes warm, even those who have natural gas, their heating units still rely on electricity to run and circulate the heat. It’s always a good idea to have at least one alternative means of heating your home should the power go out, ideally you should have multiple backup means of heating your home, or at least one room to get you through in the worst case scenario.…

Alternative uses for Reflectix

I’ve been seeing this material called Reflectix, it’s basically bubblewrap encased in aluminized mylar on both sides, it has insulative properties. It was originally created to be used as insulation in buildings, garages and such. Since this product is flexible like a fabric as opposed to being ridged, I wondered if this could be used in some clothing, shoes and such to help keep you warm without having to resort to bulky, thick layers…. I look in my mukluk style booties and there is a reflective foil layer beneath the sole, I don’t know if it is a bubblewrap product, but the foil layer is there.…
