Geothermal vs Solar Energy


One of the best ways to lower our carbon footprint is to harness the Earth's resources to heat and cool our homes. The two main methods of doing so are with geothermal heat pumps and solar panels. With both having a big upfront cost, which one will give you the most return on investment?


Climate

Solar panels require the sun to work. So, if you live in a rainy/cloudy environment, your solar panels would lose efficiency over time and provide unpredictable service.


Geothermal heat pumps use the Earth's heat, and the further north you live, the more heat is needed during winter. They also provide 500% more efficiency than gas or oil heating, making it a better option than solar in colder climates. That means the further south you live, you'll have more sunny days and need less heat, making solar panels the better option.


Cost

Geothermal heat pumps are more expensive, especially in retrofits, and require a lot of piping and excavating. Solar panels are fastened to a roof and can even be leased for $0-$3,000 or bought for $15,000+. Geothermal pricing depends but is averaged around $20-30k.


ROI

The initial cost of one of these systems shouldn't be a deterrent because both have a payback rate of about 7 years when you take into account tax rebates and increasing fuel costs. Both also make the property more appealing to potential buyers.
