Folding for free

post #1 of 14
Thread Starter 
I found this on sale and i was wondering how low of wattage a system can run while folding. I have alot of old computers in my basement, mostly pentium 4's and folding seemed kinda interesting but i know my dad would kill me when he saw the electric bill. Anyone ever try running a computer on solar panels? With say 135-190 watts could one run a folding rig cpu or gpu? How long would it take to save money by using the panels vs paying by the kw/hr?

You would be way ahead paying the added amount on the electric bill than trying to power those rigs off solar panels.Are you a certified electrician? working with the AC voltages required for your power supply can get you killed if you make a mistake.

You need a battery and an inverter.

Its a kit, very safe to handle.


It will take DECADES to pay it off if you manage to buy everything needed.

You would never save money really, as all your using your free energy for is to displace your new expenses... The installs can be rough, and the current is unstable(day to night, weather) and would require you to monitor the output constantly.

Ya I have considered solar panels to offset the cost of folding but our home is surrounded by trees so thats not really an option. You are probably looking at about 5000 to cover the cost of 2-3 folding rigs. From what I can remember most people spend about 10-20k with the expectation that that will pay off in about 5 years or so. So buying better hardware and folding on that is going to be cheaper. I dont even fold on my older core 2 duo as the points per watt are just not worth it in my opinion

You are are going to want the panels installed by a professional. the cost of the equipment is going to far outweigh the cost of hiring someone to install them safely and correctly.

folding on most pentium 4s will yield ~750 PPD. With the amount of electricity it would take to power several of the machines it would take a fairly expensive solar panel setup to cover it. most solar panels are only 10-20% efficient IIRC. Would be cheaper to build a new rig and run that 24/7 as it would have a higher PPD/watt

The concern here would not be the AC as that is simply from the power inverter connected to the 12v battery. The real danger would be the DC from the panel which if wired incorrectly could cause some problems. Honestly I don't have the desire to spend $200 dollars like that though so this is now for anyone who has the skills and desire to do this for themselves. By the way this is a much better deal.

Wow alot of posts in the time it took me to write this.

That does not appear to be a bad deal at all. You are probably going to need 2-3 times your actually usage to run only on solar power once you take into account night and the movement of the sun. So with my two rigs (using about 500watts) you would need about 3-4 of those panels plus the battery and inverter.

Only 750 PPD for a P4? Well, I suppose my laptop only gets about 2200 PPD (of course, I hardly ever fold on it... but maybe I should just overnight lol). Get a ghetto Pentium G620 and a used GTS 450, total rig cost $300 (cheapest 20GB 2.5" HDD you can find should suffice, not much RAM needed, $50 on mobo, $70 on GPU, $70 on CPU, $60 Case+PSU combo), remote desktop it with Teamviewer and you'll never have to hook up a monitor/keyboard to it.
