Solar energy can feel complicated — how the systems work, what they cost, what financing looks like, and how to keep them running efficiently once they're installed.
That's why Sol-Tek Solar is introducing "Class Is in Session," an educational series built to break down everything homeowners, business owners, and agricultural property owners need to know about solar, one topic at a time.
Throughout this series, we'll cover subjects like how solar energy works, the systems we install, financing options, maintenance best practices, and the history behind Sol-Tek Solar itself. Our goal is simple: give you the knowledge to make confident, informed decisions about your solar investment.

First Lesson: Why Solar Panel Cleaning Matters


To kick off the series, let's start with a simple question: can you remember the last time your solar panels were cleaned? If you answered no, then it's probably time for a panel cleaning.
Over time, dirt and debris build-up will reduce your system's efficiency. Scheduling regular solar panel cleanings will maximize system performance, improve power output, and help you:
- Extend the system's lifespan
- Generate more electricity and provide you with greater savings on your electric bills
- Reduce your True-Up charges
- Improve your long-term ROI
- Receive a visual inspection of your solar system while our team is onsite
Plus, your solar panels will look great, too!
