This may vary based on the age of the system and size of the home but most systems have a 25 year warranty. Since Florida only has net metering, you can only break even at the end of the year so it makes sense to size your system as close to your needs as possible. On a larger, fully electric house it can easily pay for itself in under 10 years, If you are thinking of selling in under 5 years, it probably does not make sense. It also does not make sense if you will need to replace your roof in under 10 years so it is best to install on a newer roof. You will also make the most power if you have a south facing exposure for the panels. Some quick math based on a 20kw system and a $600,000 home assuming you sell the house in 10 years.
Cost of the system: $50,000 (this includes battery back-up)
Tax Credit: $15,000
Net Cost: $35,000
Annual Power Generation: $3,500
Power Generation over 10 years $35,000 (break-even with no value add to the home)
Value add to a $600,000 home at 4%: $24,000
So if you are keeping the house for 10 years it will definitely pay for it self. If you factor the 4% value add into the equation, it can pay for itself in under 5 years. Obviously your mileage may vary but those are real numbers. Hope that helps.

I don't agree that solar panels will increase the value of your house. I think the opposite is true. Many buyers, including me, will not even buy a house with a solar system. In all of the threads on this topic, I have never seen a real estate agent provide an opinion on this. Also, I have never seen a real estate ad promoting a house that has a solar system. There is a house on my street that has a complete solar system, but it took almost 2 years to sell. Do you have any data to back up your second sentence, because I don't think many real estate agents who actually sell houses would agree with you, especially in The Villages?
