Not really. Solar panels are becoming as tied to a construction project as roofing materials, and other basic building supplies. Even after buildings are retofitted, there are always new things coming up, new technologies that are iffish now, but are maturing (tinted windows which may run at 1/20 the wattage a normal panel, but with the sheer square footage on a south side of a building, it might be worth doing, when the price for the tint becomes that cheap.)
Solar plants will continue to expand. With HVDC transmission methods, there is a lot of desert that can be used for solar, and with roughly 3.5% transmission loss per 1000 km, this can be a viable way to provide a few GW to a city. If the transmission loss is too great, it isn't too difficult to pull CO2 from the air and make ethanol, propane, synthetic diesel (Audi has pioneered this), or something similar as a way to fuel non-electric vehicles and stay carbon negative. Heck, with enough power and a source of water, thermal depolymerization becomes possible, which is an extremely good way to dispose of plastic and have a usable resource for fuel or manufacturing.
Solar technology will only improve as well. Panels may be near maximums of energy output, but better MPPT controllers and energy storage will be the focal point eventually as the bottleneck moves from panels.
The nice thing about solar is that it is stupidly easy to set up compared to any other energy source , and it is relatively maintenance free, because everything is solid state on the grid, and off the grid, the only component that wears out are batteries.
: A cast off car battery, a surplus panel, a $8 PWM charger from eBay, and some 12 volt light bulbs can power the lights on a detached building indefinitely. I don't know any other energy source that can sit there and do that. The Aussies go a step further and stick refrigerators with solar panels on them in the middle of nowhere so they can get a cold one even if on the back 40. I don't know any other energy source that can do that... nuclear perhaps, but with all the fear about nuclear, you will never see a basketball-sized reactor just for powering a small building.
