The Cost and Benefits of Solar in Alton
When picking a solar company, most homeowners or business owners worry about the costs the most. The cost of solar and the savings it generates vary depending on some important factors such as:
- How much energy costs for you: The typical household in Alton spends around $1,100 a year on power alone, so you could gain that much in savings.
- Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you receive a tax credit curretnly worth 30% of your overall installation cost, your local government may offer additional tax exemptions, credits or rebates that will help you save even more. Aside from incentives, you can save an average of $21,000 over the first 20 years with your solar system, too.
- Choice of solar panels: The type of solar panels you need will affect your total cost. High-efficiency monocrystalline panels are more expensive upfront but can also lead to more savings over the lifetime of your system. If you don't need to maximize efficiency, you can go with a higher number of more affordable panels.
- Your location: This influences how much sunlight your roof gets, which helps determine how many panels you need.
Solar is a valuable investment for most homeowners. You can generate your own electricity instead of paying for it from the grid and make use of solar incentives and rebates, all while helping the Earth.
