Question by jchaines: Can I buy JUST the SunPower 300 Watt panels without being required to use the installer I bought them from?
I have been looking everywhere (web retailers, ebay, amazon, etc.) trying to buy SunPower panels but the only places I seem to find are the "Premier Dealers", and they force you to have that dealer install the panel and therefore you can't buy just the panel...
Can anyone help me with this? I am only looking for the 300 Watt or greater panels...

Answer by RudydooHey J, you're correct. I spoke with Jane at Sunpower customer service today. They may be telling you that they are, "Premium Dealers," but in Sunpowers case, they only allow their certified dealers to install them. She claims it's because of warranty coverage, personally I don't buy it. I can purchase a $ 30,000 automobile today, take it home and change the oil, rotate the tires and flush the radiator, but if the vehicle acts up or the radio quits, they still cover it under warranty.
On a note closer to home, we have a 1.6 kilowatt solar array on our garage roof made up of 14 Kyocera KC-120 panels. One of them failed recently, and Kyocera replaced it for me free of charge. I installed them myself 9 years ago, that was okay with them, as is the case with most panel manufacturers today.
Sunpower claims to have the most efficient solar panels on the market today. If their claim that their panels are 18% efficient, than they are correct. Most panles today are around 13%, which means 13% of the suns energy is converted to electricity, and the other 87% becomes heat. The additional efficiency only allows you to produce the same power in a smaller space, there is no cost benefit to it, in fact, I would suggest that their higher efficiency and premium dealer arrangement actually makes their product more expensive per unit power produced. So at the end of the day, you can spend the same, or more money for an array that runs your home and takes up 25% less space on your roof. For most people, this is of no concern. To give you an example, we power our home with our 1.6 KW array, and at 13%, it takes up less space than the roof of our single car carport, about 85 square feet. Most homes have roof structures that are 5 - 10 times this space, this is why most people opt for more popular brands of panels that are easier to find and purchase, might be less expensive, and allow them to do the work themselves. There are dozens of panel manufacturers out there, Kyocera, BP Sharp, Evergreen and Sun to mention a few. If you have the space for a slightly large array, then all of these products can work for you.
