When considering a solar panel system, it's important to also factor in additional expenses such as inverters, mounting hardware, and installation fees. The total cost for a complete solar energy system usually falls between $1 to $3 per watt, meaning that a full system using 540-watt panels could cost anywhere from $1,080 to $1,620 per panel before any tax credits or rebates.
Most solar panel systems do not require much regular maintenance or upkeep. For instance, you may opt to wash off the panels if they are obscured by debris. If you prefer to entrust that type of work to a professional, expect to pay several hundred dollars per visit. Perhaps more importantly, as the homeowner, you’ll want to monitor the generation capacity of your panels regularly; if the capacity starts to drop and it is not due to weather events, you may need to consult with a professional.11
While the initial investment in small solar panels may appear steep, the long-term savings can be considerable. On average, solar panel systems can save homeowners between $10,000 and $30,000 over their lifespan, which can be 25 years or more. As electricity prices continue to rise, generating your own power becomes increasingly appealing. Small solar panels can lead to significant energy independence, allowing homeowners to rely less on grid electricity.
