Solar panels can be a valuable investment for future buyers they've been recently installed and when you’re living in a location where it’s becoming the norm. If lots of homes in your area have solar panels, and buyers are learning to expect them, adding them might give you something extra to promote your home when it comes time to sell. However, if few homes have solar panels and buyers tend not to pay for the investment, you might not get back the money you put into the panels. And you may find that house hunters in your area don't like the look and it could deter them from buying in that area. Solar panels can be a hinderance once they get older, and you also want to make sure you're aware that if you are leasing the panels and decide to sell your home during the lease it will be nearly impossible for buyers to secure a loan to purchase the home. Often banks won't even grant a buyer a loan on a property if there's a leased solar package involved. Also, if they come with a warranty, make sure that the warranty is transferrable to the new owners if you ever choose to sell.

Hi Crystal!

I don't think installing solar panels would affect the price of a neighbor's property, even if the roofs are connected, such as in your townhome situation. One would have to see the property to get an idea of the visual impact. A poor quality installation might have an effect on your home values. Adding solar panels may or may not ADD value to your home, depending on where you are located, whether the panels were bought or leased, and other variables.

As far as clients I've worked with, some people like the way it looks and some do not. Others like the benefits and others balk at the cost. So while it may not affect the appraised value of your property or your neighbor's, it may limit the pool of buyers for yourself and your neighbor in case one of you wants to sell in the future.

Will your HOA allow them to be installed? Reach out to them first to see if it is an option for you. Also , how long do you see yourself living in your current home? Will you be leasing the panels and for how long? Just a couple of questions to keep in mind because a 20 year lease for the panels may deter a buyer should you ever decide to sell.
