You need to do the math on your average monthly power bill over several different years verses the cost of Buying/Leasing a Solar panel setup. If it ends up being a wash from a cost perspective then all you are doing is adding more risk to your power utilities. If its only saving you a marginal amount of money every month then its not worth the additional risk. You also need to do research on the realistic long term reliability and function of solar panels over a 5, 10, 15, and 20 year period.
Usually these solar panel options make zero financial sense without substantial Tax subsidies. The likelihood of tax subsidies going away is far greater than the local power company raising the costs of utilities out of control.
In my research for doing solar on our house it would have only saved us about $10 - $20 a month verses without. At that rate of savings it would have taken almost 30 years to pay off the panels if we purchased them and it was a total wash if we leased it. This was also assuming that the tax subsidies and power buy back rules would stay consistent over that same 30 year term.
The reality is that solar panels are currently not efficient enough or powerful enough to be a viable replacement for standard land line power provided by the utility companies. Solar panel technology is improving every year so maybe some day they will be good enough to be a viable replacement without needing to be subsidized. Until that happens it will always be a less than optimal solution for many home owners that have a bunch of city or county restrictions on how they can be deployed. The utility companies are also going to do their best to make solar a losing proposition for as long as they can. This is no different than the Oil & Gas companies doing whatever it takes to circumvent development and innovation on alternative fuel vehicles.
