The Cost and Benefits of Solar in Collinsville
For many people, the decision of which solar company to go with comes down to prices. There are a few factors you should consider when trying to determine how much it will cost and how much you can save, including:
- 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 generate as much energy, which will leave you with lower savings on electric bills than a house with a roof that gets a lot of sunlight.
- Your energy consumption: If your home uses a lot of energy, you'll benefit more from going solar.
- The make and model of solar panels you're thinking of getting: Some have higher prices, so that will shape your budget for your solar project.
- Incentives: Tax-paying citizens who install a solar energy system this year can save 26% of their solar installation costs by taking advantage of the federal solar investment tax credit. You can also save about $12,000 on your utility bills over 20 years not including incentives.
Solar is a rewarding investment for most homeowners. You can produce your own energy instead of paying for it from a utility company and take advantage of solar incentives, all while helping protect the Earth.

Environmental Impact of Switching to Solar in Collinsville
One of the reasons so many are considering going solar is to help lower their environmental impact. But how much can using solar energy instead of traditional energy actually affect the environment? In Collinsville, where the energy generation produces a lot of greenhouse gasses, going solar can have a significant effect on the planet since solar power is an abundant source of clean energy. Because solar panels don't release CO2 emissions into the atmosphere when creating electricity, they're a good trade 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 benefits outside of saving money. One of the primary ones is that you can help save the Earth too.
