Factors that Affect Solar Panel Costs in Alton

For many Alton homeowners, the decision to install a solar energy system rests on cost. However, the range of solar installation costs can be quite wide in Alton, with typical prices between $20,000 to $40,000. There are a number of factors that significantly influence the price you'll pay, which we'll go over below.

Solar Equipment

The size of the system you need is one of the largest factors that determines the overall cost of going solar. For that reason, it's important to accurately gauge the size of the solar energy system needed for your home by figuring out your average energy use. The type of solar equipment you choose can increase or decrease your cost by thousands or even tens of thousands of dollars. If you opt for the most efficient solar panel brands, you'll end up paying more upfront than if you opted for the most affordable panels. However, higher efficiency could save you more in the long run on your electric bills. In addition, add-on products, like solar batteries, can bump up your total well above the Alton average.

Solar Financing Terms

Many homeowners find the average cost of solar in Alton to be too expensive, even if the investment pays off over time. Fortunately, nearly every solar company in the area provides access to financing options. Solar loans remarkably decrease upfront costs for most homeowners, but they also lead to paying more over time due to interest. Even though solar loans make going solar more accessible for Alton homeowners, they can also add to the total you pay for your system, depending on your interest rate and how long you take to pay off the loan. If you make a larger down payment, though, you can cut back on how much interest you have to pay.

Solar Panel Installation Company

The solar company you opt for to handle your switch to sustainable energy can play a role in your total costs. There are about 3 solar panel companies operating throughout Alton, and each can charge different amounts for labor and equipment. You may come across national solar installers that have lower prices because of their larger brand name and access to bulk pricing, or you might see small, local installation companies offering deals or specials to compete with those major players.

How to Save on Solar Panels

There are a lot of solar installers to choose from, all of which offer different warranties, solar panel models and price points. To help you decide on the right company for you, here are some tips to keep in mind:

  • Solar Panel Brands: The model of solar panel you'd like plays a role in which company you should opt for, since different companies provide different panels.
  • Warranty: Many companies offer different types of warranties that provide different kinds of coverage. A 25-year, all-inclusive warranty is the gold standard.
  • Contract: It's important to look over your solar installer's contract closely to understand what services they will provide, what the warranty covers and what you can expect about the cost.
  • Reputation: Your solar installer should have a solid reputation as a company and have proven expertise in the field. Two ways to check this are to look for whether a company has technicians certified by the North American Board of Certified Energy Practitioners (NABCEP) and if it has good reviews from previous customers.
