The Cost and Benefits of Solar in Alton
Solar panels run off a free energy source — the sun — but before you can take advantage of this you first need to pay to set up your system. Some key things that impact the cost and possible savings include:
- Incentives: Something that can make your solar project cost less is the solar investment tax credit (ITC), which is a tax credit that's equal to a percentage of the project cost. You can also save a decent amount of money on your energy bills, which can generate an average of $15,000 of savings over 20 years.
- The amount of sunlight your area gets: Due to Alton's high amount of average daily sunlight, you should be able to save a decent amount on your power bills.
- Your income and budget: This determines what kind of solar panels you can afford.
- How much energy costs for you: The average family in Alton shells out around $990 a year on home energy use alone, so you could gain that much in savings.
So is a solar system worth it? Whether you're trying to lower your energy bills, carbon dioxide emissions or both, solar panels are a worthwhile investment for many Alton homeowners.

EcoWatch's Alton, IL Solar Company Rankings FAQs
What is the most reputable solar panel installer in Alton?
The highest-rated local solar company in Alton is Mobius Solar, with a rating of 5.00 stars.
What are the biggest advantages and disadvantages of going solar?
A few of the biggest pros are that it reduces your power bills, it's good for the environment, and it provides a significant return on your investment (ROI). The most notable cons are that solar panels don't produce electricity at night, the startup costs are high and solar panels can be an eyesore.
Is it worth putting solar panels on my house?
Solar panels call for a considerable upfront investment that usually costs at least ten thousand dollars, but whether or not solar panels are worth it depends on a range of factors like local electricity rates and the amount of direct sunlight your roof gets.
How often do solar panels have to be replaced?
Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they should be disposed of. What this means is the amount of energy they produce will have decreased significantly after that point. You can opt to replace them after having them for that long or you can continue to use them at a lower efficiency after that time.
