ORIGINAL: thompsonx I've been off the grid now for about 13 years. My solar panels are doing about 82 percent of what they did when new. How do you know this? Which is fine in the summer. In the winter I'm running the generator more often and for longer periods. Perhaps if you were to add some more pannels you would not have to run your generator so often. Not to mention the $8,000 I just paid to replace 3,000 pounds of lead acid batteries that I was lucky to get 11 years out of. This is nothing but a lie. Deep cycle flooded lead acid golf cart batteries have a usable life of 5 years if you are running for 11 years no wonder you cannot get a full charge on your batteries. Golf cart batteries weigh 60# each so 3000# would be 50 batteries. $8000 divided by 50=$160 per battery...more bullshit since they can be had all over town for @$80 per copy. I have a meter on my power system and I operate my system closely. Now of course your meter has a log that gives you a look minute by minute because it would not be too productive for you to sit there for 11 years keeping an eye on shit. Hence, getting things like 11 years out of batteries by knowing how to best operate the system. Not you nor anyone else is allowed to break the laws of physics The discussion was not about adding more panels it was about a life expectancy of a panel. Your comment is off point and mute. Really????If your pannels are not working according to the guarantee then that is your problem not mine. If you would rather bitch than solve the problem knock your self out. My solar panels are on a simple freon operated track rack that is simple to find with google. They'll basically generate about 45% more energy since it passively tracks the sun. I saw that concept in an old mother earth news using propane tanks and propane. I don't use Trojan T-105 batteries you're describing. I use the Trojan L16 that weighs 125 pounds each in three groups of eight batteries wired to 48 volts DC. So 24 x 125 = opps you're full of shit. Since l-16 batteries cost about twice as much per amp than golf cart batteries one would have thought someone who claims to be as smart as you would have gone with the gc battery. Deep cycle batteries do not have a life expectancy based on years, they have a life expectancy based on cycles (usually approximately 300) and maintenance. So your explanation of cycle life is also = opps you're full of shit. http://www.solar-electric.com/deep-cycle-battery-faq.html#Lifespan of Batteries Battery Lifespan The lifespan of a deep cycle battery will vary considerably with how it is used, how it is maintained and charged, temperature, and other factors. In extreme cases, it can vary to extremes - we have seen L-16's killed in less than a year by severe overcharging and water loss, and we have a large set of surplus telephone batteries that sees only occasional (10-15 times per year) heavy service that were just replace after 35+ years. We have seen gelled cells destroyed in one day when overcharged with a large automotive charger. We have seen golf cart batteries destroyed without ever being used in less than a year because they were left sitting in a hot garage or warehouse without being charged. Even the so-called "dry charged" (where you add acid when you need them) have a shelf life of 18 months at most. (They are not totally dry - they are actually filled with acid, the plates formed and charged, then the acid is dumped out). Well let's see, obviously you went and googled what I was explaining to you and you've quoted that here to look smart. That makes you look very bright. Golf cart batteries, designed for use in golf carts = 0.58 per AH L16 batteries, designed for off grid systems. = 0.61 per AH Which means your cost twice as much = opps you're full of shit. Golf cart battery energy available to run house = 675 AH L16 off grid battery energy available to run house = 1305 AH So, your comparison of the two = you're full of shit. Still waiting for your magic bean battery information.
