Solar Panel technology has improved incredibly over the recent five years, so now the old scare tactics should not be used anymore, but they are.
If you are approached by a solar company that tries to convince you that you should not own your solar system, instead you should lease it from them, and because they try to scare you with "What happens if it breaks down?" or "Are you prepared to pay for repairs?"
Independent studies are showing that the solar panels, inverters, racking systems and monitoring systems are lasting past their manufactures warranty date, meaning that in all likelihood, any repairs would happen 25-years or more from now.
Do your own research and beware, be smart.
