Solar Panels and Grid-tied System
 
I just Installed 39 230 watt panel and the project is complete and has been inspected by our local electric coop and we're producing power. I was just posting this so that if anyone had a question, that I could probably help because I built this system from the ground up.

any details on the install?

area of country?

total install cost ( with or without labor ok ). maint costs expected?

cost per KW of electricity locally?

actual or estimated production so far? over the course of a year?


I just want to get a feel for what payback is or is expected to be.

Ive always been intrigued by Solar as a supplement, but the numbers have not worked out yet to be anything close to other items such as more insulation/better windows/etc.

The payback for the 8000 watt system and panels and wire costed around 20,000 Dollars and will provide around 1600 to 1800 kwh per month. You also will get a 30 percent rebate back, meaning you will invest 20,000, but after the rebate/tax break it willl only cost 14,000 dollars. If you count alll the factors up inflation, a system like this will actually pay for itself in about 6 to 8 years.:thumbup:

I also have a facebook account with the whole project, My name is Shaun Foster and I'm from Puxico, Mo. If you want to check out the pics feel free to do so ....:thumbsup:

Shaun - you got some nice equipment there. I know KW rates are cheap in the Ozarks, I think .10 a KW and I also know that most Co-ops don't pay the full .10 for additionally KW produced. They typically pay what it costs them to create power, and in KC with KCPL it's about .009 a KW.

What panels did you use?
Are you at max inventor capacity with 8900w of panels and only an 8000w inventor?
How much did the Co-op charge for the disconnect box? Were you forced to buy an automatic transfer box, so if power goes out it doesn't charge the power lines entering your home?

Love the idea of solar power and I want it so bad, but costs are still to high, especially if you don't have a Southern facing house that can get all the daylight out of the panels.

EG,

Once you open a reply window, scroll down the screen below the text reply box and you'll find a section called Additional Options. The second section of that is Attach Files. From there its pretty straightforward... navigate to the desired file, select it, and then click Upload.

Best way to include photos is to upload them to photobucket or somesuch then copy and paste the <img> codes in your reply or in a new message here. I'd love to see them. Would probably do this myself but the roof is too high and steep for me.

We did some serious price shopping and got the panels @ 71 cents a watt.
The inverter has a combiner box that mounts directly with the inverter that holds 4 strings, but we fully loaded the inverter with 3 strings on 13 panesl wired in series. Each panel is 30 vdc. So 30vdc X 13 in series = 390vdc,
Local Coop supplied the meter at no extra cost, but we did have to buy the diconnect box. No transfer switch is needed, because if the inverter does not see 240 vac coming to it so that it can see the sine wave to syncronize , the inverter will show a fault code and will not energize, it is a built in safety feature to protect the lineman is the grid goes down. So basicly is the grid goes down, we dont have power either. We may get a battery bank in the future.

Inverter pics and other stuff.

Looks good. Nice to have the room to build a low structure dedicated to the panel install. Alls I have is my roof, which I never thought was an ideal place due to height and how to handle future roof maintenance issues.

Hello. Your solar system looks impressive.

Do you mind discussing in detail how you grounded your solar panels, equipment, etc in regards to an earth ground? Any thoughts on grounding and how to approach it with a small solar system such as mine. See below

3- 80w 12v pv panels wired in parallel mounted to roof approx 30ft from earth
225 AH battery bank
15a mppt charge controller
1500 watt inverter
AC breaker panel connected to inverter

Thanks!
