The Cost and Benefits of Solar in Castle Rock
The cost of putting up a solar panel system has dropped significantly in the past few years, but it's still a substantial investment for most homeowners. The cost of solar and the savings it generates vary depending on a few important factors such as:
- Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you deduct 30% of your overall installation cost, your local government may offer additional tax exemptions, credits or rebates that can help you save even more. Excluding incentives, you can save an average of $21,000 over the first 20 years with your solar system, too.
- The kind of solar panels you can afford: This hinges on how much you're willing to spend upfront.
- Energy consumption: Solar may be too steep of an investment for families that don't use too much energy a month.
- The amount of sunlight your roof gets: If your roof doesn't get a lot of direct sunlight, your solar panel system won't be able to produce as much energy, which will give you lower savings on energy bills than someone with a roof that gets plenty of sunlight.
So are solar panels worth it? Whether you'd like to decrease your electricity costs, carbon emissions or both, solar panels are a solid investment for many Castle Rock homeowners.

Solar Incentives in Castle Rock
Although a solar power system is typically a big investment, it can save you a considerable amount of money in the long term due to reduced energy bills and government incentives. These incentives usually consist of cash rebates, tax breaks and/or performance-based incentives. They can lower the cost of going solar by 30%, upwards of 50% depending on your location. Check out our article on solar incentives to learn what incentives you can benefit from.
Environmental Impact of Switching to Solar in Castle Rock
There are a few primary reasons why people want to invest in solar energy: for the good of their bank accounts and the planet. But how much can using solar energy instead of traditional energy actually affect the environment? Everyone can help protect the planet by switching to solar energy, but homes that consume a lot of energy will have an even greater impact. Since solar panels don't release carbon dioxide emissions into the atmosphere when generating electricity, they're a good swap for traditional energy sources. In fact, you could expect to reduce your carbon dioxide emissions by about 100 pounds each year. As you can see, going solar has so many other rewards besides saving money. One of the primary ones is that you can help save the planet too.
