Solar / Re: Fixing solar panels, I did something stupid
Last post by bigrockcandymountain -
I'm pretty sure it is ok the stuff i used.  It says "sensor safe" and smells rubbery, not like vinegar. 

Permatex ultra grey rtv gasket maker i think is what it was.  I know the orange stuff smells like vinegar, but this stuff did not.

Ah chinesium, But well made, and they knew it, still get these some what cheap!

But like any thing china they over blow the realistic current handling of the onboard relays and I cooked one, luckily easy enough to order new relays and repair the board, but lets not do that again, good thing same people sell some thing for that, while add it lets add a 40 amp psu!

Well great, I have the brains and one axis working, but following it up and down isn't too useful, we need azimuth, lets see the junk pile and see whats laying about!

Solar Trackers / My tracking system
Last post by Xeonpony -
Some one asked about my avatar picture on another forum, it was my very first kick off to off grid living. They where thin film amorphous panels from Canadian Tire, back then they had a claim of 30w each and I had 120w by the label, I never saw more then 50 out of it! So to try and improve it (fruitlessly) I made it an adjustable and turn-able mount

How I get my power!.JPG

Crude but worked excellent, far better than the panels ever did!

Getting sick of the garbage I finally ordered some real solar panels, whopping 540w and man did they crank the juice out and work fantastic.

Back then 3k! including shipping!! (Now days I could buy a 4kw array with that! but still going 16 years later I got my dollars worth from them!)

Gave away the crappy amorphous panels and lived off those for some time, but after enough moves I put them on the old static manual tracking mount.

Effective, but gets tedious having to go out side and push it into the sun especially in winter! So lets automate! but on a budget!

Heating, Cooling, Lighting / Re: My miniture waste oil heater
Last post by Xeonpony -
Guy I know in the next small town east of me used to burn waste oil... he got tired of nozzles plugging despite filtering the old oil, filter prices went way up... he put in an outdoor wood boiler instead. Less work since he has kids who cut wood for him. Most doesn't need splitting, just shove in a bunch of 4' long logs and let it go! Will burn 24 hours on a crammed full load. His neighbor doesn't like that though! Gets a wee bit heavy white smoke when throttled back and packed full.

We have that too, gravity does the bulk of the filtering for you! where most go wrong is they try and run on the bulk tank, imo that is just for mixing and pre-settling, you want a small heated day tank, the heat causes the crap to fall out of suspension.

You drain sludge just before you fill it, then you filter the sludge, as for the feed filter you only get the reusable ones and have a couple spares, so just swap em as needed

It is a hands on venture and cleaning every month to 3 months depending on design, but once tuned, it just works.

Some of those images are quite large. I’m trying to save space, so I don’t have to triple my server cost for storage.

I increased the attach image size to 7mb and the number of images per post to 7. Hopefully that will be enough.

The image I was trying to upload was 400kb, yet it flags it right away, I'll try and see. This was in the solar tracking sub forum

Most forum software has an option to autosize images to the forum needs... I haven't looked at what the forum software package is so no clue if it is an option.

...  I used to sell some astronomy accessories into Canada, a group who combined orders to cut shipping costs.

I was one of those customers!  Still have the Bahtinov mask for my scope.  Still use it, too.  Always got the stars pin-point sharp.

to bad they got so stupid on shipping up there! USPS went nuts on pricing...

I do remember on the original forum that several founders did the same of skewing the magnets to lessen the cogging problems. If I remember correctly, this wasn't a big problem until the Sumerian-Cobalt <-sp? and higher powered mags started coming down in prices. I don't thinks this is/was ever a problem with ceramic mags.
I could be wrong.
Cheers

Exactly.  I had already learned my lesson by then, even at the time I built that motor conversion.  Maybe 2010, people like Zubbly and Peter Dingemans and Jerry had it all figured out.  I just had to do what I was told...

right now a ton, and that is desired in this unit as it is mostly air heating, second chamber will be made larger and fully insulated for the boiler.

Now I am working on a small heated carburetor from an old pot burner for it, as mixing gasoline in is getting tedious

I did the math and for 4L per hour I need 250 to 300w to ensure cold oil will be at proper temp.
