Certainly can get things cheaper but I think unless you are going to be doing the actual install yourself it probably makes the most sense to hire a contractor who would both install the system and also sell you the entire BOM.saleem145 wrote: 1. Can I get these items cheaper -- what is the recommended supplier??

3. What is a good estimate for labor costs??
4. Any recommendations for an installer in Connecticut??

State of CT will give me $2.275 per watt for system up to 5 kilowatts in size. It works out to $11,375.
And Federal Govt will have me 30% of net costs.
Couple of questions --
1. Can someone confirms the CT rebate?? I have read different numbers in different places??
2. How do I apply for the CT rebate??
3. As far as Federal Rebate is concerned I understand it is 30% off the different of cost of system minus state incentives??
4. How do I claim the Federal rebate. I understand that I need to file some form with my taxes. Question is which one??
5. Does everyone quality or AMT or something else can reduce the amount??
6. Can I get a check from th federal govt as opposed to this being part of tax process??
In WA we use a rule of thumb that for every watt of a unshaded DC PV will generate 1 KWH of AC annually. So a 5,000 watt DC system should produce at least 5,000 KWH AC. There are a lot of variables that go into that though. Getting a solar evaluation will help get a realistic number based on your site. http://www.nrel.gov/rredc/pvwatts/" onclick="window.open(this.href);return false; can also help.saleem145 wrote:
Next here is power usage --
Last month I used 865 kWh and my bill was $142 which works out to 16.4 cents per kWh. My average consumption has been 810 kWh per month. (This excludes the Leaf I am buying).
Questions here are --
1. How much electricity can I expect my 5kW system to generate on average per month in kWh. And what would my savings per month be??
2. I presume if I am a net producer of electricity I only save on the cost of production, as opposed to transmission costs, etc which seem to be roughly 50% of the total bill??
Once your get some more firm answers to the questions you've been asking it will be interesting to see how the payback of a 5kw system vs a 10kw system ends up being.saleem145 wrote: Only disadvantage in CT is that the state incentives are not as attractive for systems beyond 5kW, so that will have to be the size I settle for. I do not think I will be a net producer but should be able to cut my electricity bill in half!!
The Enphase M215 each need a "trunk" cable which is an additional $30.saleem145 wrote:Hello,
I will need (from EcoDirect.com) --
21 Canadian Solar CS6P 240P panels @ $259.95 per piece
21 Enphase M215 micro inverters @ $148.95 per piece
Total is $8600 so far.
Racking, electrical box, etc. Best to hire a contractor to install and have them buy all the other smaller parts.2. What else will I need to buy -- I want a complete bill of materials??
That's mainly dependent on your labor market, and even then there are huge variations between contractors.3. What is a good estimate for labor costs??
The federal incentive is not a rebate but a tax credit. It will reduce your taxes owed.3. As far as Federal Rebate is concerned I understand it is 30% off the different of cost of system minus state incentives??
No.6. Can I get a check from th federal govt as opposed to this being part of tax process??
Look up PVwatts for a rough estimate.1. How much electricity can I expect my 5kW system to generate on average per month in kWh. And what would my savings per month be??
The treatment of excess electricity depends on your state laws, specific utility, and rate plan. I'm not in Connecticut so can't help on this one.2.

Mark, thanks for responding! It's exciting that everytime I hear from you your price has dropped. I think you got the original poster and a responder mixed up though. Maybe you'd be willing to take a vacation to Connecticut to help saleem145 out?Mothernaturesolar wrote:San Jose inspectors require that the GEC connections are to be done only with irreversible crimps, so make sure that your contractor knows this. The rebate process with PGE/CSI is lengthy and convoluted, make sure that he knows how to do the paperwork correctly. 20% of PGE rebate applications are not finished, and therefore not paid out. And the PGE solar meter application has 4 different parts to it, also make sure that he is familiar with that one.

You can expect approx 8,750 kwh of solar production your first year, if your panels are faced anywhere from 180 to 210 degrees, and if you have no shading issues. You're doing it the logical, and hard, way to save money on a solar system. But sometimes the logical way isn't the best way.
You're up to $1.89 per watt cost with the material pricing that you have so far, and you haven't yet factored in the racking, flashing/mounting, wiring, grounding, breakers, conduit, delivery time and cost, time spent for the PGE rebate application and meter application, taxes or labor.
Installers get a lower price for product than you can, and if they are reputable they will pass along the savings to you, the consumer. Most are not, however. The average installed price in 2012 (here in California) is almost $6.00 per watt, based upon the California Solar Initiative statistics.
For a complete 5.04 kw system, materials and labor, my price is $3.49 per watt installed ($17,589). I do all the paperwork- building permit, PGE rebate, and PGE solar meter, for you. Your only additional cost would be the cost of the permit, which in San Jose is about $300.
I'm not the one looking was was looking for a new system.
But just for the record, last month, buying the major parts myself and using a contractor for the rest, I just did a 2880 W addition to my system for $8454, which is $2.94 installed. That was using some Talesun 240W panels at $156/piece and some Enphase M190 at $99 a piece. After incentives - the small $0.20/watt CSI rebate, and the big 30% federal tax credit - the net price will be down to $5554 . That is $1.93/watt installed, inclusive of all taxes.
The total cost is less than your $3.49/watt, and it's only a 2880W addition to my system - a 5kW system would have cost even less per watt.
$6/watt before incentives is the price I paid in 2010 for my initial 6580W system. Total system cost was $39,679 before incentives. And $26,321 after incentives. Ie. $6/watt before incentives, $4/watt after incentives.
Prices have come way down since 2010 however. Only someone living under a rock would pay $6/watt now. It's very sad the CSI is reporting that as the average price still.
