They almost went belly-up after nearly merging with Sun Edison while S.E. was in a tailspin about a year ago. They're still one of the 5 largest installers of rooftop residential PV in the US, based largely on leases & power purchase agreements ( PPA) rather than outright purchase. The industry trend is toward purchase, which is usually a much better deal if you have the credit to finance it. With any lease or PPA deal watch out for annual price escalators, which are usually well in excess of average inflation. With the relentless and rapid price deflation of solar and wind power, there is good reason to believe that electricity pricing should trend downward over the next 10-20 years, not upward, as the cheaper-newer renewables are putting all fuel-consuming generation sources back on their heels. Even if the PPA price today is below grid-retail, if there are annual price escalation clauses there's a good chance you'll be paying more than retail in 10 years, maybe sooner.
