If you are static mounting them (vs on a system that tracks the sun) realistic you might get 30% of rated capacity ( and lose to conversion if going to AC ) per hour of daylight unless you are washing them off frequently they will get dusty/dirty, clouds, rain, ice/snow ( if more north ), bird poop, etc etc.
Living more northern than Florida/etc reduces efficiency as well, and the components probably are not ALL going to last for 5yrs+ so you'll be fixing it and investing money and testing and maintaining ( and potentially a fire hazard )
Then you also have to look at the investment potential in some cases people are spending 20k plus that's not an insubstantial amount of money, invested in the s&p500 in the last decade it would have earned a good amount likely outpacing the savings of solar.
I guess it's also nice we live in a relatively low cost of power, I think we are paying like 0.09 per KWH so it makes it really difficult to show a 3-5 year ROI which is what I generally look for... Maybe if I was paying closer to 40c per KWH I could see it but you just have to math it out and the variables for your specific scenario.

If you DIY the return on investment is 6 to 7 years in most cases. If you pay a professional it's more like 15 to 20 years on a system that probably last 20 years
