Startup cost: $200 - $1.5k

Setup costs for a solar panel cleaning side hustle typically range from $200 to $1500. At the minimum end, you would need basic cleaning supplies like a squeegee, cleaning solution, and a soft brush. On the higher end, investing in a water-fed pole system for efficient cleaning, protective gear like gloves and safety harnesses, and a reliable transportation method for reaching client locations would be advisable. Optional expenses might include setting up a basic website for marketing purposes or investing in online advertising. Recurring costs could include transportation expenses and ongoing supply replenishments. Online sources suggest that costs can indeed escalate once you commit, especially if you opt for high-quality equipment or additional services. To take this side hustle seriously, budgeting around $500 to $1000 upfront for essential tools and marketing efforts would be a prudent approach.
