But you may be curious — how much exactly can you help the environment by making the switch to solar? No matter where you are, you can help the planet by switching to solar energy, but homes that consume a lot of energy will have an even greater impact.

What are a few of the pros and cons of installing solar panels?

Solar panels can be a beneficial investment for many homeowners, but admittedly, they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight or your electricity bills are already reasonably low, solar panels might not be for you.
