Thanks for posting very interesting and compelling viewing. I’ve been using solar power in the UK for about 5 years now just in the RV and I have never had to plug it in to the mains to charge any of the 6 110 AH batteries. When the RV is just parked up I plug all my outside lighting in to the RV this also helps keep all the batteries in tiptop condition.
I also built a solar water heater panel I think I still have the video and pic’s some where if anyone is interested. I never posted it anywhere has it was a bit boring. At one point I had steam coming out of it. I have also experimented and built a solar panel it came out at about 18v 620ma. And that’s what compelled me to invest in the panels I now have on the RV.

| feel free to move the post... i think a solar section would be a good idea... can't wait for these new 12foot square 'flat screen' thin film panels to hit the market. saying that though, i like the big reflector array in seville best of all... |

my batteries for my bedini are now charged by a single 12V 150mA soler pannel sat on the gararge roof...
What can i say... someone complained i was wasting power with my experiments...
Solar power is excelent... the downfall is that even the high density pannels are huge compaired to their output...
in order to go green manufacturers are going to have to start looking at the efficiency of their products...
I once calculated i'd need a 2 X 2 meter pannel and a 150amp 12V battery to run my laptop 24X7... not good!

or manufactures must do something about the high amp input of their laptop...those things r not exactly efficient yah know...:P
1 thing is sure...theres plenty room 4 (grrr cant think of tha word i need now)...but i know u know that i know what i wanted 2 say so i know i dont need 2 write it...haha...lol

price is what tha company r thinking about....so yah didnt know what i thought u know that i knew that u knew what ima wanted 2 say...okeee...ima getting confuse now...:)...nah...anyway
but i do think that they need 2 make those panel suck up more sun light than they do now...4 that i suggest that they look in the nature...:)...nature holds lots of secrets...we just have 2 discoverd them...:)

| i seem to recall that solar thermal systems are more efficient than PV panels because PVs only abosrb energy across a small part of the spectrum... alot of the suns energy is outside this narrow band and only heats up the panels reducing their efficiency... by concentrating and using the suns heat to turn water into steam which drives a turbine, it's fairly easy to make DIY solar systems that work over a broader range of the EM spectrum... |

i remember a couple of stories where some people were trying to make DIY solar panels were arrested under the terrorism act coz someone phoned the police because it looked like they were creating a bomb...
As a precaution, my next door neighbour knows what i'm doing... I often discuss engineering type problems with him... that way, he knows what i'm trying to do and doesn't get the wrong idea... and he also helps...

So this may seem like a silly question... I certainly feel like I'm asking something for the thousandth time...
But... I'll ask anyhow
I'm planning on purchasing a small solar cell, 16 volts at 160 MA.
It's about 15 bucks from an internet electronics store here in the states.
The question I have is, why not run the solar cell through a solid state Bedini and charge a bank with it?
It seems like the charging potential would be MUCH greater than the cell alone and 160 Ma is way more than enough to run the solid state I'm running.
I'm currently running 12 volts @ 40 MA and getting 220V spikes to charge with.
What do you think guys?
Thanks,
-Trait- |

I can't see a problem with doing that...
What i would say is that you might want to run two charger... saves wasting any power...
Personally, i have a similar solar panel...
But it charges directly...
Simple reason being that i have a primary and AUX battery setup...
The panel balences both batteries...
My pulse motor stuff runs from the primary and my various RC chargers etc etc run from the AUX...
Yes the aux battery gets hammerd at times... lol

My thought is...
By running the charge through a coil and using the BEMF to charge we could hook up to a bank of 10 batteries or so and save ALOT of PV cells for the same charging power.
I agree, we wouldn't want to waste the power, but for instance... You could analyze the spike and based on your voltage set up a bank to take away the most from your charge. Once charged swap to a second set and run the first set in parallel to invert.
Just thinking in text really...

BUS BARS!
the best thing is to charge ALL your 12volt batts at the same time... when you use one you disconnect it from the power lines, use, and just re-connect...
Use seperate diodes for each battery, then when you put a completely dead one on the power won't flow from the charged ones to the dead one... Also, by doing that, the system will automatically balance all the batteries...

this is one of the very best and simple yet very effective and cheap solid state self triggring radiant oscillator or charger...
please give me your feed feed back and views...
i had recently desulphated 3 of my 5 years old 12v 80amp lead acid car battery...now they hold a charger quite properly....
and i had simply use a 1amp 9v pus or power supply for input...
heres the link to circuit.....
download it and enjoy---

Shubs,
Why have you posted the exact same post here in the SOLAR POWER board and on the SSC thread?

Well it looks like many of us are looking into Solar energy, I know I have and started thinking about a system that would track the sun.
After heaps of reading and searching, actually found someone not that far away from me that has been doing this for a number of years and rather than re-invent the wheel, I decided to pay him a visit.
Upon me seeing his website:http://www.campatracka.com/
I actually purchased some gear from him and have now build myself an automatic solar sun tracking system that keeps 2 - 80AH batteries fully charged and puts power back into the grid using a small 250watt Grid Tie Inverter. The reason I am doing this is that I have 2 - 80watt solar panels wired parallel and they put out just under 10amps all day because the system tracks the sun. I have found this to be very efficient in producing extra power, so why not push it back into the grid.
The small black solar panel on the side of the large panels keeps a small 12v - 7.2Ah sla battery charged, that operates the actuators. At dusk a light sensitive resistor kicks in and moves the panels back towards the East, ready for the next day. The white box houses the sla 12v battery and the solar controller and has to be water proof against bad weather.
The Grid Tie Inverter is a simple plug in system, so no electrician is required to wire the system into the grid, one simply plugs into a socket. I found this system on ebay for $130 au dollars, and decided to give it a try. When I have nothing running in my house, I noticed that the meter was slightly moving backwards, so I must be saving electricity.
I have been so impressed with this system That I am in the process of building a 1.5kw system using a heavier set up and 6 - 250watt panels ( 4.725 x 2.478) The linear actuators need to much heavier and have ordered them already. I also have to use heavier 40amp relays to operate the actuators and have this well on the way.
If you are interested in what I am doing, why not visit http://www.campatracka.com/ and see what David Harvey has done and also some of his customers around the world. I also build a parabolic tracker using evacuated tubes to heat water and again this could have major advantages by tracking the sun on a daily basis.
I will keep more information coming as some of these projects are completed.
Yes...free energy is out there, the trick is to harness it in the most efficient way and a tracking system seems certainly the way to do it.

Hi Hendo, nice panels they look just like the one’s on top of my RV.
I have never had to run mains out to charge the batteries. I have fried 8 batteries to date but that’s over 6 years or so, and that’s my fault for not having the time to top up the batteries now and again. I did build a small solar water heater panel and put together a video on the construction but was a bit embarrassed with some of the comments I made and the temp device I used in the video. I did at one point get steam out of it. Sadly I never installed it or did anything with it or the video.

Hi Daftman, looks like you have been thinking along the same lines as me. During last winter my heating bill grew almost 40% with natural gas and electrical cost becoming quite expensive and now the government here are talking about introducing a carbon tax on top of it all, which would increase these costs again.
I started to test a theory using a parabolic mirror and I then decided to make an electronic sun tracking system, which I have working on 2 - 80w solar panels. I intend to build 1.5kw system next and have already purchased the actuators and build all the controls to run it. I understand that the cost of panels is going to reduce quite a bit over the next year, so it may pay to wait a little.
To see what temp I could get, I prepared a small video for you to look at. I am getting, on a sunny day 266 degrees centigrade and some times this goes over 300 degrees.
http://s459.photobucket.com/albums/qq313/hendo1944/?action=view¤t=parabolic_test.flv
I was most impressed with this and have decided to build a series of parabolic troughs with evacuated special glass tubes in it to either heat water or hydraulic oil. Hydraulic oil in earth moving machinery can get as hot as 200 degrees centigrade and has a very low flash point. I would use a small solar powered pump, to pump the oil through the trough (10 of them) and the return is to an insulated holding tank. These troughs automatically track the sun during the day to increase the efficiency. From this tank I would run two flexible lines that would go to an internal radiator that would heat the house (room).
I hope you like the idea and I look forward to anyone that may have some comments.

Do you have a diagram of this? More info please, I am setting up
such a system, and at present have differing AH rated batteries.
