Who has already installed solar?
#1
Wondering who has implemented solar in PA? Did you take advantage of godvernment subsidies (or other subsidies)... what prices are you getting for your REC's? Who are you selling REC's through? Do you know what a REC is?

Ill start... Ive got a 7770w grid tie array, (37) kyocera 210w panels, (2) fronius IG4000 inverters, datalogging.... and its PAID for in 3 months!

The system generates a tad under 60% of my total usage - Ive got kids so this is how I reduced my utility consumption. The next project is to swap out the grid-tied inverters and put in something that will island and work in conjunction with a generator. I found out the hard way during an extended (5 day) outage that the array is shut down without the grid being up - the inverters must shed excess power somewhere and grid-tie wont work otherwise.

Anyone else looking at something similar?

Do you mean in 3 months you own it? How much was the initial outlay, and/or how much per month were you paying on it if financed?

I'm going to echo Camper's question. I have thought about solar for a long time, but with all the changes in technology and subsidies I haven't pulled the trigger yet. I talked to a solar sales guy a few years ago and he recommended waiting until the newest cells were released onto the market but I haven't followed-up.

When I called a couple places about solar, they didn't want to bother because the benefits wouldn't suit them too much....but I don't want to lay out several thousands for installation, I wanted to lease the system.

Yes, that's my question too. Do you mean you put in this system 3 years ago and it will be paid off in 3 months ? I'm not being nosey, I just want to better understand what you are saying.

Oh I didnt break even in 3 months... that would almost be too good! I went live Jan 2010, gross system was $53k. If you factor in the rebates, federal was 30% of gross system cost ($15.9k), State contribution was a 'rebate' of $2.25 per watt ($17.5k), then PPL chipped in another $5k (another 'silly' rebate), that brought the net cost to $14.6k

So here is how I get to paid-for in under 3 years... Im generating close to 10MW annually, at a burdened cost of juice approx 12.5 cents per kW, that works out to about $1.6k - $1.8k annual electric production, not much in the scheme of things, but thats not my play. The REAL money is the "funny money" or REC's this project generates. In year one I was getting $400 cash per REC ($3600 for the first year), and that held for about 18 months. The price fell out in PA due to oversupply, but Ive since entered a long-tern contract to sell them... and I also found out my broker was holding many of the past REC's, so I got a big check for them. Im counting on a Q4 REC check that will bring my system to paid-in-full status (including the production numbers).

The math isnt an exact science above (sorry, Im NOT sharing the exact monthly run rates, but you can get the picture... its close to $5k in annual "mailbox money" if you count everything... now as far as depreciation and CAPAX recapture, well thats all in the accounting Tongue

That's excellent. How many hours a day do the panels receive light...and are they static or do you have them set to follow the sun ?

Since I know the OP and have seen his system, I am going to state for him that they are fixed panels on his roof.

Without going any further about his system, I can tell you that a movable system is WAY too costly for a home owner to re-coup and it would not add that much more KW to the average day.

If you have a roof that is facing south or better yet, a little southwest, you have an ideal mounting platform. A ground mount system is the next best setup as you can face it exactly in the best direction and maintenance is much easier to perform.

Best prices in the WORLD for Generac whole house generators when you get to that phase:

The system gathers light all day, whenever there is light. As far as actually doing anything meaningful, that's a different story... it really needs direct sunlight to produce any real energy. For example - the sun rises at 6am, its directly overhead at 1pm, and sets at 8pm (example hours)... the production curve is very "bell shaped", meaning its slowly ramping up for a couple hours, then aggressively shoots up to several kW of production, than begins to arc with a peak around 6-6.5kW and taper back down to almost an exact inverse of the morning ramp up period.

As for the power outputs - it will fire up around 6:15 (takes about 5 minutes to sync to the grid upon start-up) and begin at 20watts or so of production - really an insignificant amount. You can watch the display on the inverters climb up to several hundred watts each, then around 10ish the main roof shoots up to 2500-3500 watts very quickly.

Overall its working if the sun is shining - but not necessarily doing anything meaningful without direct sunlight. As Mikey pointed out - you can put this on "trackers" (as they are called in the industry), but you'll find that that mounting system is expensive (and you'll most likely need a zoning variation... your gonna piss of some neighbors with those), and you'll absolutely need construction permits. The roof mounting is far cheaper (and in my case cost LOTS less, net cost) especially if you can play the subsidy game. I originally looked at installing 3 trackers till I found out how expensive that was going to be (also spoke with one of our township supervisors who Im personal friends with and got an "education" on the zoning variance process... I would have had to put these in an easement, just not worth the effort or time). All said and done, the roof mount system is larger and actually blends into my home quite well. As Mikey said, you need south/southwest exposure - and that for me is the front of my house! I thought this was going to be a tough sell for my wife, but she sure like utility bills under a hundred bucks (and the mailbox money from REC's).
