I have a separate question which may be a bit newbie on the solars. If SPWR is producing 300+W panels in their X series, then what is the competitive edge of the others? I know we're all very fond of CSIQ and JASO etc, but what gives their panels an edge in comparison. I'd guess two main components. Firstly SPWR is probably limited in volume how many 300+W panels they can produce. The second is possibly price / W. I'm guessing the form factor is about the same so W / m2, would be in SPWR favor, which may not matter for industrial installations if the price per W is lower. As I don't know the retail or volume pricing of the panels it's hard to guess. I think TheShadows could possibly answer this somewhat.
This question has two reasons behind it. Firstly as an investor I'm trying to figure out a bit more on the products (though management and execution matter a lot as well, one of the reasons I'm deep in CSIQ LEAPs and low valuation provides good opportunities of growth hence why I'm deep in JASO LEAPs as well) as well as am planning a solar installation for my home at some point (hoping to get my solar stocks to pay for it easily). Btw do we have a thread somewhere about what to build at home, the best equipment from panels to inverters etc?
If you plan on living in your house a long time then I would recommend using SunPower panels with the PowerOne inverters.
Other companies make panels cheaper, and they are competitive for that reason. The Chinese companies are making panels for as low as $0.50/W whereas SPWR makes them for a little more (I don't know exactly the number because they don't provide it, but I remember them talking about some numbers around $0.80/W but it could be a lot different).
Some people claim that solar panels are commodities and will buy the cheapest panel per watt. But the truth is that longevity and degradation play a huge role and people tend to be ignorant about these things.
SPWR said that their new plant will make cells 10% more efficient and bring the cost per watt down by 35%. So they should be able to catch up on price very quickly to Chinese competitors, because they can't bring their costs down by 35% next year, maybe 10% if they are really lucky. That is why I am a big believer in the company and think that it will be a long term big time winner. I think that SPWR will be a 10-bagger over the next decade or so.
Let me just add that SPWR has a 25 year product and production warranty, while Chinese have 10 year product and 25 year production warranty, so if your panel breaks after 10 years, you are SOL.
I am putting a Sunpower system on my roof next week.

I don't think this is the case at all. For example - We are a 1 income family as my wife currently stays home with our kids. We wanted to go solar, not just for the savings, but for environmental reasons too. We could have used our entire cash savings to pay for a solar system. Or, we could work with SCTY to put a larger system on our house where our savings (including paying the lease payment to SCTY) will have a similar <5 yr payback period. And the SCTY system is under warranty and any maintenance in covered. If a panel fails? They'll replace it.
So yes, in a perfect world, we could have bought a system outright, but the leases can be very advantageous for someone not willing or able to put that much money into it.
Side note: I've been lurking the investment threads for a while, thanks to you all for your valuable discussions!
Sure! We're at just under 3k sq ft, two story house, two A/C units and a pool pump outside Phoenix. We have a N/S facing roof so we get full sun on the panels all day. Our system is a 7.92 kW system that generated just shy of 14.5k kWh last year. Our lease is for $89/month for 20 yrs (could have been cheaper if we prepayed more, but I think we only prepayed $1500) and our electricity bill has dropped ~$140 as a result of the solar system. It's actually dropped more than that, but partly due to some other changes (switching to Nests, finding our installed whole-home filtration system was set to run at a horribly inefficient speed) so it's hard to nail down an exact number.
So I guess looking back, our break even point is about 2.5 years.
And I would absolutely work with SCTY again. The installation process went very smoothly, and they took care of the small issues that came up during inspections very quickly.
Sorry, but I don't really have time to make the full response to your post that I wanted, but wanted to point out that you just proved my point on what I said about Solar City customers:
You do not understand the concept of payback period, and that is probably why you signed the lease thinking that you got a good deal. Your payback period is not 5 years or 2.5 years as you stated, but rather 13 years. And that is ignoring degradation, which could make your payback period worse offset by higher electricity prices in the future, so it is a wash.
You are going to pay roughly $23k over 20 years, and then Solar City takes the system away from you or you have to continue paying. Even though Lyndon Rive said today that expected system life is 30-35 years (and probably 40 - 50 years with a SunPower system). So you do not get the benefit of getting free electricity after the system is paid off. Solar City also "steals" the tax credit from you and gets the benefit of it.
Here is a quote someone posted on a solar forum, and it is in the same city as you live in Chandler, AZ:
Utility: SRP
(40) Bosch Aleo s79 265 Mono Black Panels
(2) SMA5000TL Inverters
System Cost: $30,740.00
SRP Rebate: ($500.00)
Out of Pocket: $30,240
Tax Credits: $10,222.00
Net Cost: $20,818.00
System Size: 10.6 kW
First year production: 18,743 kWh
Current Annual Usage: 19,500 kWh
He will pay $21k for his system, while you pay $23k; factoring in time value of money (or interest expense on a loan) lets call it a wash.
But your system is 7.92kW and his is 10.6kW, so he is getting a 33% bigger system for the same cost.
I have said this many times, but people always seem to pretend to be ignorant on this topic: you do not have to pay cash up front for a solar system; their are many loan options available. I got a 5 year 3% loan for my system from a credit union. I googled credit union solar loan and first link I hit had 4.24% loans for 5 years or 5.74% loans for 7 years. You can also take a HELOC loan out.
Lastly, while this guy will enjoy a 33% bigger system than yours for roughly the same price, he will get to use that system for free after the 20 year period is up which you don't get. So he will get another 10-15 years on average of usage.
Add all of this up and this guy is saving over $30k - $40k more than you are over the 30 - 35 year period.
And lastly if he were to decide to sell his house, say 10 years from now, his solar system will probably add at least $10k to the selling price. While your lease system becomes a liability.
Oh, and by the way I am putting up a 7.68kW Sunpower system for about $9,000 after tax credit and utility rebate; and this is in not solar friendly Texas. I will get to use the system for at least 25 years fully warrantied (except for maybe the inverter that might be 10 years, but those are relatively cheap) and possibly up to 50 years with very minimal degradation compared to the cheap Chinese solar panels that Solar City uses. Guaranteed 87% of original production after 25 years (their tests show better results than that).
Lastly, I am not trying to say that SCTY is a bad stock, because I am sure that there are plenty of ignorant people that will gladly sign up to lease the system when Solar City shows them that they are going to save you $50/month or $20k over the life of the lease. It sounds like a good deal, until you go shopping around and realize that you can buy a solar system that will save you twice as much over the life of the system.
Solar City will need to keep cutting costs and offer the systems a lot cheaper in the future to become a good financial option; and I am sure that they will be able to do this. But I am pointing all of this out for those who are considering putting a solar system on their roof. Please do not sign a lease with Solar City, it really is a bad deal financially. Find a way to finance a system and buy it, so that you own it.
You will save tens of thousands of dollars if you buy a system instead of leasing.
