Photovoltaic systems and you: Lovin' the sunshine.

A few weeks ago there was discussion in another thread about rising energy costs and photovoltaic systems. I lost track of that thread and was super busy at work. I figured I would make a new thread to focus on the topic of PV systems and how they may help. Quick recap: I work at an accounting firm and one of the clients assigned to me was a leading installer of PV systems here in CA. I do not represent this company but became fairly familiar with the tax implications of installing one of these systems.


Disclaimer: Figures below are not exact. I am going off the top of my head but I can verify all the numbers if needed. Last I checked my client was moving away from residential jobs and focusing more on commercial systems. My boss handles another photovoltaic account at work and I am pretty sure that guy is focusing only on residential, so either way I can get you in touch with the right people if needed. Also, keep in mind that I am only doing this to help, I am not trying to sell anything to anyone and I could care less who you get to install it. Don't flame me if I forget to cross a "t" or misplace a decimal point. Finally, I am not giving tax advice - if you want tax advice you can send me a PM and we can setup a time to either talk to myself or my boss. I don't want to be responsible for someone dropping cash on a system then getting mad at me if it doesn't work exactly as explained.

This much I do know:

*The CEC handles systems under 30kw. The PUC handles larger, commercial systems. The funding is limited meaning that there is only so much money in the pot. If all the rebates get reserved then you are up poop creek (until legislation changes or more money gets allocated). Also, the money gets reserved quicker in certain areas (higher demand areas) because the funds are allocated to each utility company. This is how it was until recently. There have been changes as of Jan 2006 and I will need to get up to date on them.

*The federal tax credit jumps to 30% of the net system cost (total cost less rebates and incentives) and is limited to $2,000 for residential jobs (there is no limit for commercial installations). You can only get the credit for 1 installed renewable unit per year. You can however, get an additional credit for installing a solar water heater. Last I checked this credit carried forward 10 years

*State tax credts are gone as of Dec 31, 2005. I will check to see if there is anything in the works for the near future.

*Tax credits are limited by AMT. If you are hitting AMT you are pretty much screwed.

*From experience, I noticed that most residential contracts ranged from $18k - $35k obviously depending on size and need. The only thing I am hazy on is the calculation of Kw. For example, I know that a 77Kw system cost $xxx, but how do you determine Kw size? Is it based on daily output, potential max output over a given time? Perhaps someone here can clue me in on that since I am not an electrician. If I know this then I can give you a rough estimate of system cost. Worst case scenario I can get a quick quote from my client.

If you are installing a system for business purpose, the tax benefits and savings increase dramatically. I can go into more detail if requested.

As far as a group buy, if enough people are interested there may be a possibility of some sort of discount. Lets cross the bridge later.

PS - Regarding the HOAs. I know it is a PITA but somehow there is a way around it. I overheard them talking about it a few times. Some HOAs maybe more of a pain than others though.


Hope this helps. Please post any questions.

I am interested.
Would you have a break down for:

1 KW system ~$?
5 KW system ~$?
10 KW system ~$?

Out of pocket and approx. rebates

Thanks Simon
 
Speaking of loving the sunshine... if a major roof-top installation is feasible where you are, then Solatube skylights may solve your reef tank lighting costs for a fraction of the expense to install a PV system. So Cal gets more than enough sunny days to keep your corals happy, but I think you have to get the kind without UV protectant coating.

You could always add actinics for color.

Why am I thinking a local reefer had these installed not too long ago?
 
I priced these in LA a few years back. There was a 2 year wait list then and near the end the % of subsidizing was reduce about 50% so it wasn't worth it. I also was sick of waiting. I think I needed about a 3 KW system to be off the grid and that was around $40K. I think I would have had to pay about $25K.

Does anyone know if you can buy single panels and add to them over time?

I think that you have to have a license to install them. I know that you need to get a permit and have the city inspector come and sign off on the project to qualify for the rebate. The system usually needs to be connected to the main power grid.
 
Your PM is full Super Noob.

Would you mind posting the phone # for your client who does residential?

BTW, thanks for taking the time to post all this information. I think I am ready to chock up the $$$ and buy a system. Just need to find a licensed guy with a good rep and a better price :)

We installed a 5KW system for our house a couple of months ago. It cost approximately $40,000. But we are supposed to get a self-generation rebate of about $8000, and I think Edison is going to give us a $12000 rebate. We've been on solar energy for the past month, Edison sends us the bill, but we don't pay. At the end of the year we're supposed to get a report of how much energy was generated and how much we used, but we aren't supposed to pay anything because we are generating 100% of our usage. Pretty much our entire roof is full of solar panels. I'll take pictures and post them on here when I get home.
 
I just called a few guys and the price seems to be about the same as what you paid. It takes about 8-9 years in savings to pay back the cost of the system. I don't know if it's worth it as I don't know if I will be living at this same place that far down the road.

I can swing 18k-20k before rebates but not 35K.
 
I exagerated when I said it covered the entire roof, now that I climbed our roof. We have 32 panels installed roughly 2.5" x 5.5". i post more pics in a sec as I downsize them.

I asked because there is a house down the street from me that has about 10 panels on the roof. I don't think it takes care of the entire electrical demand, but every little bit helps.

I wonder what a system that would cover my tank, washer/dryer and refrigerator would cost?
 
I actually don't have any skimmers or metal halides on my tanks. We mainly installed it because of our outdoor koi pond. It used to be a 2000+ gallon pool with fountain, but one day we decided to turn it into a koi pond. We didn't change out the filtration and we were wasting a grip of money having it running 24 hours instead of 1-2 hours daily. We still haven't upgraded the filtration, I think it's a hayward sand filter and a 37000 gph pump. It was funny when we tried adding on a pond filter to the existing setup, after it was plumbed we blew up the pond filtration because the maximum flow was supposed to be 3000 gph.
 
Super NooB I emailed the company you posted the link for the first time and they never responded. I am very interested in getting an idea what a system would cost and possably doing it.
 
I believe you can install these yourself, but you must have a license professional inspect it after you install it. I was looking into this about 2 weeks ago.
 
The panels run about $500 a pop depending on the brand. The inverters are a couple thousand as well.

Laverda: Not sure why nobody responded. When I am at work on Monday I will give them a call. I will PM you my work email so maybe you can remind me on monday. Once I walk through the doors there I turn into a robot so I may need a little nudge ;)
