RE: The 12V power source solar panel

Lots of good options presented here Niner. But one thing I am curious about - has anyone actually connected a Bucker and verified pseudo MPPT operation? Some things on paper pencil out just ducky but up jumps Mr Snag or Monkeywrench. Myself I would not mind seeing a performance report card. But then a couple of panels and a BOOSTER is definitely viable. I wouldn't mind seeing a test of a booster connected to a Farad grade capacitor when is then routed through a reasonably priced PWM controller. This would make paralleling those inexpensive panels a real bargain. 2 Farad capacitors can be found online on eBay or Amazon. Boost panel voltage to 17-18 volts. Then pass it through the controller. To eliminate conflicts use an in-series rectifier between the booster and the controller. This should be a piece of cake parallel wise. Why a rectifier and not diodes? Also specs on the Farad capacitors? I ordered another Solar 30 today... I got the last one drenched in MT last trip and it's now DOA. Gotta mount it internally this next time, not under the portable solar panel, out in the fatal elements. Should there not be a 2 Farad capacitor available at Apex electronics surplus in Sun Valley?

RE: The 12V power source solar panel

I was speaking to your situation directly, just noticed the shipping was as much as the panel. Noted, and not applicable in my situation, would be an over the counter sale, just like if I drove down to Solar Blvd.

RE: The 12V power source solar panel

Did anyone see the shipping? Did you note in my first post that these guys are local to me? Like 4 or 5 miles tops?

RE: The 12V power source solar panel

Not enough voltage to charge a battery by itself. Put 2 in series and use an MPPT charge controller and it will work fine. You could put more than 2 in series depending on what the voltage limit of the charge controller is. Two with my $13 gizmo limit at 32v almost as good as MPPT? Easier as a portable with two small panels instead of one big heavy one. Link to your $13 gizmo unit and what it does?

RE: The 12V power source solar panel

"Maximum Power Voltage ( Vmp)11.97V" I don't understand this either. I suspect it's in error. It is not in error, there are only 24 panels on it, at .5V each. Most 12V Battery charging panels have 36 panels on them at .5V each, for 18 Volts output, under maximum load. They then burn some of it off with a charge controller to get it to 14.8 or 14.4V to charge a battery with. This is more a Power Supply panel for day time use, not a battery charging solar panel.

RE: Proper Wiring for two controllers to one battery bank

Paralleling different panels with different electrical characteristics to one MPPT controller is not a good idea.Not sure why that would be always true. It's pretty simple to try it and see the amperage reading at the controller. It is because the "knee" of the IV curve is different in the two different panels. That "knee" is where the MPPT controller observes the characteristics of the panel's output and determines how to sort voltage, amperage and resistance. Think of it this way: The MPPT controller is lecherous. It likes to rub knees. If it has Charlise Theron in on one chair and Rosie O'donnell in another chair, it will get confused and start examining just Rosie's leg rather than Charlise's appendages. The result will not be pretty. I can't erase that from my mind... I am feeling gravely ill after visualizing that nasty scenario.

RE: The 12V power source solar panel

I await mexicowanderer's input on this also. So if you need 14.5ish-15.0V to gas, you need 29 or 30 solar cells at .5V each to get that? At that point, does a charge controller become optional? The amps rating on this solar panel with PWM looks pretty darn good, if you could get the voltage to a usable level to recharge. Surplus voltage or head room, unless under direct sun, no clouds, looks a bit thin.

RE: Is this PT's future?

I like the re-roofing idea with solar panels instead of rubber,but it looks expensive per square foot?

The 12V power source solar panel

So I came across this on EBay... and they are very local to me... but it sounds like a $100 experiment gone bad. The specs on this thing are waaaaaaay different than any other 12V solar panel that I've ever seen. Max V 15.03V? Amps at short circuit 7.92? Vmp... 11.97 Could someone with more brain power than me check the specs on this and tell me it would charge a Trojan T-1275 without even the need for a charge controller? What about diodes and sucking juice out of the battery and back into the panel? Thoughts? Funky Spec'd 100 watt panel with huge amps. Do you run this with one of Mex's Voltage buck / boosters, then through a charge controller, so that there is enough V to charge a battery properly at bulk mode, 14.8V and give up a few amps in the process? Need help, guys, but in layman's terms, EE's and above need to dumb it down to terms a Finance major can handle.

RE: Portable Solar Controller

They might have something really nice if they put some 10 gauge wire on that and made it a 20 or 30 amp adjustable bulk charge voltage portable controller. 5 amps is mouse nuts.

RE: Proper Wiring for two controllers to one battery bank

If you have two matching 120W panels, those are each close to 7 amps each charge rate. Why even bother screwing with the 50 watt solar panel and it's measly 2.5 addtional amps, when you already have 14 amps? Get another matching 120W panel if you can, and sell the 50 watt panel. 120W panels for 89 AH group 27's AGM's is plenty, for most applications. Next time when your replace the Group 27's Trojans, consider 6V T105's instead. Much, much, much easier to keep charged, they don't have the crappy acid to lead ratios that car type sized batteries do, so that the damn battery can fit under the hood without shorting out at the terminals. Trojan should make a T-105 AGM Side terminal batteries for cars already, for no shorts. When you match batteries, you should match panels also... seems to me just to be common sense.

RE: Buck Your Solar with a Mex Gizmo?

If I could get away with 200 volts 400 volts, 600 volts I would use that preferably. But that's dreaming. 80 at max will have to do and hopefully two or three Buckers connected in parallel to render 45 amperes max charge rate. Now to go grab a hatchet and find the piggy bank. It's hiding. Lin tells me China industry gossip has the country projecting the manufacture of eight million plus panels for the month of November 2014. Almost double that over 2013. Ships carrying raw material from Australia are lined up at ports, and railroad trains carry the material to manufacturing centers. African countries have been purchasing millions of panels. China is determined to sell more than ONE BILLION panels in 10-years. It is mind-boggling. He said automobile lithium batteries are in Beta testing phase. That country has big plans. I hope they don't turn it into a hazardous waste dump with toxic air. He said coal fired electrical plants have turned many regions into areas with perpetual brown sky and 1/2 km visibility. China to Mexico telephone call. I wonder how many NSA computers went whirring on that one? Thanks to a donated GALAXY 2 cellular and headphones I was able to understand Lin's heavily accented English very well. I look forward to lithium technology replacing lead acid. Don't go blaming me for you getting investigated again by the NSA because I gave you a phone. You know, now my name is on a file or dossier at NSA just for donating you that phone. Don't screw it up for me! Until the USA loosens their pollution standards to that of China, we will never be able to compete in manufacturing, globally. The clean up costs get added into the price of every widget. Clean air comes at a steep price. You should see what it costs to replace a Diesel Particulate Filter on my VW Touareg diesel. Outrageous!

RE: UPDATE! Ordered a 2015 Eco-Diesel today! :)

Our 2008 Honda CRV AWD would get 26 MPG on freeway, the 2012 Touareg with 3.0 TDI and AWD and 5000#s gets 30 -32 mpg, all the time, when not towing a trailer, a bit less come the cold of winter, maybe 28 or 29. Hoping Dodge Perryboy gets his Eco broken in soon enough so we can see some towing numbers for mpg come next spring, when it warms up a bit.

RE: UPDATE! Ordered a 2015 Eco-Diesel today! :)

I've no interest in drag races. The comparison is retarded, abuse of equipment, and in no way related to real world experiences between the two vehicles. It's useless information.

RE: UPDATE! Ordered a 2015 Eco-Diesel today! :)

4200# of 64ft square here behind a 3.0 TDI in a Touareg... 16.5 to 19 MPG, when towing at 58 MPH. Confirmed over about 16k miles of towing now in 2.5 years. It helps that the tires are 14", inflated to 55 psi, and limited to 55 MPH MAX speed rating.

RE: Fuel Prices

$3.59 a gallon for Unocal/Conoco 76 diesel in Los Angeles today. Wondering how long it will last, think I should buy 500 gallons.

RE: How Much solar to Add??

I appreciate the mostly constructive answers. Others shouldnt even post. We dry camp at the most 7 days at the moment, however that might change. We do not use the lights much the main draw in the summer is the water pump for dishes and showers. We do not use the bath houses.. In the spring and fall the heater blower would come on. Those are the main draws. From what I gather the more the merrier and certainly if it was just a weekend I would consider less. I believe that i will be increasing the battery bank, undecided if Ill add two more T-125's or sell them and get a pair of L16's upfront. Space and adding hitch weight are something to think about. I will start with around 500 watts or so with two panels, leaving space for more to add of we need it. We want to downsize our generator as the Honda 3000 is 135lbs and humping that up and out is getting to be a bit much. I want to sell it and get a pair of 2000's. One would be plenty to run on cloudy shady days to bump the batts up. A 2000 only weighs just under 50 lbs. Once I find a good sale and install I will post for others to learn fro as well. While there were alot of posts. I wanted to hear from real time issues. Happy Trails!! Here's some free advice... Seek professional help. You can't believe what you read on the internet. Or use the search function and help yourself, this has been covered over, and over and over. You remind me of wives that hired a contractor for a remodel, that sign the contract, with a certain scope of work for a set price, then keep changing their mind wanting more and more expensive material, that didn't do their homework before signing the contract, yet they still somehow thing the price should be unchanged. Until you define and figure out your needs doing an energy audit, there is no right answer. You have to learn how to crawl, before you can walk.
