Hi Manisha. It depends on how long you plan on keeping the house. Depending on the cost and how much you may save per month after installation, you should expect any between 5 - 10 years to break even. I would not count on solar panels increasing the value of your property. I know that the solar panel companies use increase in value as a selling point, but in my opinion there's not sufficient statistical sales data to support such a claim. In my market, I have seen very few homes with solar energy panel sell and it's therefore very difficult to draw a comparison. This may change in the future, but right now I don't see the increase in value as a prime motivating factor for making the investment. If you opt for solar panels, do it for environmental reasons, not for cost efficiency reasons. That's just my opinion.
