There are no Arizona or utility rebate incentives on solar systems. There are Arizona and Federal tax credits and/or rebates that may apply to your situation. See Renewable Energy Incentives
This inquiry is best met by direct contact with the various non-profit organizations and for-profit businesses. The Arizona Solar Center's Resources Directory is a good place to start.
These articles contain descriptions of how Arizonans have used a variety of techniques to reduce their energy usage.<< Link not working

The so-called “cost-barrier” to PVs is overstated. Costs are not a barrier to large systems, remote systems, systems where competing costs are high (e.g. Japan), or when environmental costs are given any consideration at all.

Yes. The solar energy device must meet the required criteria except for the warranty and professional licensing requirements. The value of your own labor is not allowable for tax credits, only out of pocket costs.
The Arizona Solar Center is not currently hiring. However, we suggest you consult the GreenStart Job Board on the American Solar Energy Society website (www.ases.org ). They have jobs posted in the solar energy area. Our own Internet site has many links to sources of information on renewable energy as well.
Internships are also possibly available from individual companies. We suggest you contact them directly. And there are many internship programs you should be able to find on the Internet. Among them is the Environment and Energy Study Institute (www.eesi.org ) in Washington, D.C. Their telephone number is 202-628-1400. Their job and internship board can be found at www.eesi.org/jobs .
