Solar panels will likely be worth it, depending on the details of your specific situation. If you use very little energy or have very cheap energy, you won't be saving as much money each month and it will take longer for your panels to pay for themselves. And if you live under deep tree cover, rooftop solar panels likely won't generate enough electricity to be worth it.  However, solar can pay off in energy savings for decades. Lowering the cost with rebates and tax credits will help pay off your solar panels faster. How you pay for your solar panels will affect that calculation, too. It'll take longer to recoup your costs if you take out a loan, which will accrue interest and come with fees. You can calculate your payback period if you know the cost of solar panels after rebates and how much you'll save on energy costs each year. Most importantly, be sure you're saving money by shopping around and finding the right solar panel system at the right price.
