Photovoltaic (PV) technology (aka solar panels) is advancing steadily. That advance will occur regardless of whether we have an economic depression or booming prosperity. This advance means that price of PV modules are dropping at a rate of 7% per year (as it has been doing that for decades). This means that by 2020, the price of a PV module (with micoconverters etc. included) will likely be close to $1 a watt (not including installation, which is also falling). That puts PV tech within the range of being cost competitive with today's alternatives. As an added benefit, it's possible that modules that approach this level of cost efficiency might also be locally printable (as in: they could be made in a 3D fab or grown in a bio-lab).
The implication: for those communities able to deploy it in quantity, it will mean increasingly inexpensive energy for as many years into the future as you want to project. For those that don't, you will increasingly fall behind.
There is a caveat though. The real potential for this technology isn't going to be found in a large number of big, commercial solar complexes. Why? The infrastructure and investment necessary to make this happen on a scale that really matters doesn't exist in the US or EU anymore. We are broke (and even if we weren't, NIMBY is nearly impossible to overcome as the record of new power line construction over the last 30 years attests to). So, it should be easy for us to conclude that it won't get built at national/regional level (if you think otherwise, I have a planet I'd like to sell you).
Fortunately, there is a ray of hope. For those of us building resilient communities, we WILL see this infrastructure deployed. How? Through the hard word and dedication of a resilient entrepreneur: the solar farmer. The solar producer that keeps his/her entire community fed with increasingly inexpensive and bountiful solar energy, 24x7x365 (via energy storage for round the clock production).
