Let's leave it a that, to be candid, this info is proprietary info and I'm not posting it, in essence giving out a lot time and $$ in research and development of the system.

I don't see any calcs provided from anyone else to refute mine other than a broad stroke qualitative "Just believe me".

Unless the panel is from NASA or some other govt funded agency developing a super solar cell, the facts are the maximum upper limit for today's technology is about 16 watts per sq foot. The rest is just math. As the other poster said, you can ask someone to believe you because it's proprietary but for anyone else who know anything about the technology, they can call BS.

Oh, and as for the comment about controller vs converter, please don't try to divert the issue. The point is that there is another "thing" in the system that sucks energy and adds weight, period.

So why talk about solar if to get to work you need sun

Nope, it's higher than 16, it's not just watts it's voltage and % of efficiency.

Ok, you win, it's 16.5 not 16. The 16 or 16.5 whichever you prefer is at 100% efficiency. Unless your proprietary panel is 300% efficient (makes energy out of nothing) it still doesn't support your claim that adding solar to a cart with 45 mile range will increase the range by 50% to 70 miles.

Look, I know what your claiming is impossible, just laying out some numbers with a basis to educate the less informed so they don't get sucked into the snake oiled flavored Kool aide that's being passed around.

Publish your proof and lets see some endorsements from other users. Or are you only one who has this miracle?

Many thanks for your comments. Another quick question, does your motor overheat after driving a steady 10 miles or more. Mine does.

[Bfischel]

My cart struggles slightly out of local tunnels from a standing stop. That bridge appears to be much steeper, so I was concerned about stalling on the way up. I'm glad to hear about how well yours works. Another factor, mine has high speed gears, which yield less pulling power.

[Bfischel]

I did a test run until the cart would not move appreciably, getting 58 miles. Passers by pushed me home, as I didn't plan my route well. Now my only issue is motor overheating when used for a 12 mile continuous run. High speed gears may be a contributor.

I'm also working on a end of life basis of 43 volts

Are others experiencing a similar driving range?

Also curious if this electric cart might be capable of climbing the very steep bridge over Hwy 441?

We own a Star with 8 6 volt Trojan t105's and a Yamaha with 6 8 volt Trojan Ranger 160's. Either can go 30 miles on a 50% discharge or 50 miles with a decent reserve left.
I would avoid the configuration of 6 8 volt Trojan T 875's if you regularly go over 20-25 miles-not enough reserve power.
It's not just a question of range, but also having a system that will maintain 47-48 volts at full throttle for the best performance!

Bfischel" I purchased new a 2006 Club Car Precedent I added higher gears and logically it over heated the motor. Because of this and the increase noise of the gears I switched them out for a larger engine. I retained the speed some 27mph bt fond tat the motor overheated and would come to a complete stop. so I had to wait until it cooled down to continue my trip. This stopping cooling starting continued until reached home.

I got fed up with this and replaced it with a standard motor. My cart can only go about 20mph but I am happier.

I can go from 466 to the furthest side on the north play golf go back over the bridge back home and my analog meter is still on fully charged.

I was one of the first to install a solar panel (Suncatcher) but I can't honestly tell you if it adds anything to my 6/8volt Powertron batteries. I suspect I do get a trickle .

I went with my wife to test a gas cart and we hadn't left the parking lot when she said that the noise was too much.
I am told that lithium batteries work best with solar panels but at this point they are cost prohibitive .

I let the experts argue the pros or cons of solar. Finally I had heard when I purchased my panel 6 years go that one homeowner upon purchasing the same solar panel had a solar tube installed above his cart letting the sun in daily

My 2002 Club Car with six 3 year old, eight colt batteries easily goes over the bridge after I've gone 25 miles.

I saw an advertisement on television for solar panels. I wanted to know the price and a few other small details about the product so I went to the website. The website had no information but had a phone number. The person on the phone would not give me any information regarding cost but kept pressuring me to give them my address so they could come by and do a demonstration. I told here that there would be sense in giving a demonstration if I couldn't afford the product. I got the old, "you can't afford not to have this" and "it doesn't matter what the cost is because you'll save much more than that" etc., etc., "what is your address and will you be home tomorrow morning." She also said That the price is different for every cart and there is a big difference. I asked if she could give me a price range and she asked if I would be home tomorrow morning for a demonstration.
I asked her how many extra miles I could expect to get and was told that it's different for every cart. She asked for my address and would I be home tomorrow morning for a demonstration.
Click. Anyone that has to be so secretive about their proprietary product and so high pressure in the way that they do business is not going to get any more of my time.

46 volts is 10% left of charge, 43V must be dead.

I wouldn't run below 47Volts
