The Cost and Benefits of Solar in Waterloo
For a lot of homeowners, the decision to invest in a solar energy system boils down to the cost. A few main factors that dictate how much it will cost to install solar panels on your home and how much it could save you over time are:
- How much power your household needs: If your home regularly uses a lot of energy, you'll reap more rewards from installing solar panels.
- Average daily sunlight: Since Waterloo gets a decent amount of average daily sunlight, your solar panels can generally produce enough energy to power your whole home, which affects how much your electricity bills will be.
- Your income and budget: This shapes what kind of solar panels you can buy.
- Incentives: The federal solar investment tax credit, which everyone in the U.S. is eligible for, allows you to deduct 30% of the cost of your solar system installation from your federal taxes. Additionally, not including incentives, you can save about $16,000 over 20 years on your energy bills.
As a result of solar panels now being cheaper than ever as well as several solar incentives, they are a worthwhile investment for most homeowners.

Solar Incentives in Waterloo
To increase solar panel installation and usage, federal, state and local governments — and even some utility companies — offer incentives to help make solar power more affordable and accessible. No matter what state you live in, you can take advantage of the federal Solar Investment Tax Credit (ITC), which allows you to claim 30% of your project costs on your tax return, reducing the amount of taxes you owe that year. In addition, there may be some state and city incentives that stack with the ITC too. You can find out about the incentives available to you in our article on solar incentives
Environmental Impact of Switching to Solar in Waterloo
One reason so many people are considering switching to solar power is to help reduce their environmental impact. A question many people might have in mind is how much can they really help protect the environment by switching to solar power anyway? Your energy usage is an important factor to keep in mind. The more power your household consumes, the bigger your impact when you switch to solar energy. While solar panel production emits carbon dioxide, the panels make up for it by significantly reducing the amount of CO2 you would have produced if you still used traditional energy. In Waterloo, you can reduce your carbon footprint by 90 pounds a year with solar panels. The good things about solar power are plentiful — just like solar power is! That's why so many people have been happy with using solar energy.

What are the major pros and cons of installing solar panels?
The biggest advantages of solar power are that it can decrease or, for some, totally cut your electricity bills, improve your home's value and lower your carbon footprint. The biggest disadvantages are that solar panels can be expensive to install, you may not save as much if you don't use a lot of electricity and it doesn't work for all roof types and locations.
Is it worth installing solar panels on my home?
Solar panels can be a beneficial investment for lots of homeowners, but admittedly, they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight or your power bills are already fairly low, solar panels might not be for you.
What is solar panel capacity and how much do I need for my house?
