Solar power

post #1 of 9
Thread Starter 
So I have been reading up on solar panels and what not. I was kinda intrested in this because of folding@home running all the time. I thought of this because I was reading markt electric bill cost and was like damn hes got to be a baller to have that setup and pay that much. So do you think it would be worth it to get a couple solar panels and a grid tie in inverter. I was think maybe this would help out with the electric bill for some of the heavy folding people. I was trying to figure out how much watt someone that folds would need to supply per hour to break even with a couple computers folding all the time.

Couldn't hurt, especially when you can get so many tax credits for it.

I've been kind of looking into this as well (it only makes sense in southern california with all the rebates, tax credits, grants, etc).

Even so, it will be pretty costly. Currently if you pay about $0.15c/kwh and have a 500 watt machine running 24/7 at 500 watts, you're looking at about $50/m in energy costs.

To get in the door with a 2kw system you're looking at $6-10,000 installed (all depends). From what I gather, you generally need to get a system installed by a contractor for the power company to approve it for grid-hookup. Either that, or rreeeeally know what you're doing and pass the power company's inspection of your equipment & setup.

a 2kw system would ideally have you produce ~10kw/day which should about make you break even with 1 500watt (usage) rig. So if you had 2x i7 2600k Cpu's only folding--a 2kw system should zero them out.

That is about a $50/mo savings in so cal. I'm looking at 10 years timeframe before my $6,000 2kw solar system pays for itself in reduced energy costs.

Granted my math could be completely off as I just started looking into this about a week ago--but that is what it seems like.

Really what it seems like to me is this:
If you plan on being at said residence for the long haul, I'd put together a system that might start off cheaper at first (to lessen initial shock costs) but can scale as you get money. Once you get up to 30kw systems you can really start seeing the benefits--but that will cost you about 80k to buy (although there are some huge gov incentives on it). Average US home is said to use about 2000kw/month so even a 30kw system will only cut your usage in half. However, that could be some pretty big savings and let you do more things that you had previously neglected (like running the AC longer than 2 hours at night lol)

edit: although if you figure something out, do share! i am still looking into this.. just have to decide if i will stay where i'm at.

It will cost at least a couple thousand or more for just a couple panels with an inverter.

Thats enough for 1cpu and 1 video card while the sun is up...
Gonna need an electrician and Power company permits, at least here in Cali so thats a few more $$

RESIDENTIAL RENEWABLE ENERGY TAX CREDITS
Consumers who install solar energy systems (including solar water heating and solar electric systems), small wind systems, geothermal heat pumps, and residential fuel cell and microturbine systems can receive a 30% tax credit for systems placed in service before December 31, 2016; the previous tax credit cap no longer applies.

I was under the impression I would need more than just the panels and inverter. Rails and other various mounting things, all the cabling, and things like depending on your geographic location--possibly panel tilters so that your panel is at 45* (to the sun, not literally 45* from ground). Then as Kevdog said, you have to get permits (local/city ordinance.. although I'm sure they pass them all since they want you to be "green", power company, etc). I am pretty sure they want a licensed electrician to come do the tie-in work to the grid, as well. You could make it cheap by literally wiring everything up to the box and letting them "hook it up". I'll bet they want to check it though. Or at least claim they have to--regardless if it is already done correctly or not.

Wherever there is fat government rebates and incentives to spur the industry, everyone will want their piece of the pie. It is definitely a hassle and they're not too stoked about the DIY-er solar ideas. I'm sure for good and bad reasons. Even so, 400 watt systems won't do much to ding your bill. At optimal condition (also depends how they're all rated... its a mess) in SoCal we can get ~6hours of good sunlight. On a 400w system that is 72kw/month (30 days--400x6x30/1000).

A PC pulling 500w from the wall 24/7 will use 360kw in a month (500x24x30).

This means that your $1800 (if you can really do it that cheap) solar system will make enough power for 20% of your rig throughout a month. If the cost to run that rig is $50/month-- you'll shave $10 off the bill.

Unfortunately, solar is still not that efficient in the big picture and really really costly to implement. At that rate, it would take *15* years for your 400watt system to save you enough money to break even on the cost of implementing it.

The real savings (at least in SoCal) are when you can generate enough power to keep your energy usage just low enough to knock you back into a lower tier for pricing reasons.

Ex: Normally a household uses enough power to get Tier 3 pricing (something like 0.24c/kwh)--putting in a small 200 or 400watt solar panel system throws enough power back into the grid that you can get safely knocked back down to Tier 2 pricing (roughly 0.14c/kwh). This saves you 0.10c/kwh, and if you're home is using 2000kwh/month you could potentially save up to $200/month. At that rate, an $1800 investment in solar panels would pay for itself in 9 months and continue to gain value for the owner over time.

I hope I'm not turning you off this, but unless you're on a tiered system and right on the edge (barely into tier 3 or tier 4 usage for example)--it might not be worth it. Just takes a lot of research.

Another alternative is to ask to be switched to the non-flat-rate pricing scheme. That is where they charge you based on peak usage, so during the (hot) daylight hours energy will cost significantly more than in the evening. Since your solar system will be putting power out during the hot(more expensive hours) and your pricing will be significantly cheaper in the evening, you might make out.

It all takes a lot of individual investigation since literally every home and individual use will be unique.

I had estimates done for my home and they ranged from $18k to $55k depending on how many watts you want(or they are trying to sell you).
No one I talked to suggested putting them on tilters because that means moving parts that will not last.
Here in L.A. they said the best place to put them on the roof is, first choice south side then the west and last east and with no shade.
I am in the tier 5 range on my bill witch is .31 cents a kwh so for me it would take roughly 20 years or more to pay for the system witch will only get me down to tier 3 and still save me about $100 per month at today's rates, witch they say go up an average of 6% every year.
So in the long run its good and "Green" if I never move.
