  2. Buy DIY kits available at home electronics online stores.
  3. Get solar panels directly from the manufacturers themselves.

Before making a decision, consider factors such as technology compatibility, features, and the expertise of installers. Researching different brands and dealers can help you make an informed choice for your solar panel purchase.

Here are questions you can ask solar contractors in O'Fallon:

  1. What types of solar panels do you offer, and do you have experience in installing solar equipment?
  2. Can you provide estimates for the number of solar panels needed, the overall costs, and the payback period?
  3. Are you properly licensed, insured, and do you have experienced in-house installers?
  4. Where do your solar products come from, and are they sourced from reputable suppliers?
  5. Which solar panel system is suitable for my needs - grid-tied or grid-tied with energy storage?
  6. What is your company’s track record, and do your technicians hold relevant certifications?
  7. What are the benefits of going solar, and is my roof suitable for solar panels in terms of sunlight exposure and available space?

Asking these questions will help you gather important information and choose the right solar company for your specific requirements.
