Every state is different. Your state dot gov should have some info. Panels are usually installed on 85mph wind load rails that are bolted to your roof in such a manner that the whole system can withstand 85 mph winds. Likely more in hurricane zone areas if mandated by your state.
There's the cost of the panels and then the costs of tying into the grid for net metering systems.
Payback in my state taking advantage of all the tax write-offs is supposed to be around 6 to 8 years for a average house which given a 25 year life of panels and maybe even the inverters is a fairly smart investment. Electricity isn't going to be getting any cheaper.
