Many individuals are aware of the initial costs of solar panel installation, such as the cost of the system, contractors, and permits. The continuous cost to maintain a residential solar system, on the other hand, is rarely acknowledged.

While there are some additional costs associated with maintaining your solar panels, they are normally minor and rare. Furthermore, the advantages of solar energy are going to almost always outweigh the costs you’ll spend over the course of your solar system’s decades-long lifespan.

Regardless, it’s critical to be aware of all potential costs before purchasing a solar system. Here’s a rundown of additional expenditures to consider when making a solar investment.


Solar panels possess a relatively simple development, with no moving components or sophisticated equipment, despite its outstanding capacity to convert sunlight into useable energy. Solar panels are expected to endure for the 20 to 30 years with little maintenance if put appropriately. As a consequence, there is not much to be concerned about in terms of routine upkeep.

However, you must keep a constant check on the physical state of your system, ensuring that the panels are clean and debris-free. If the panels are dirty, one can either let them be washed by rain or use a garden hose to clean them (from the ground).

You should also keep an eye on your system’s energy output levels to keep an eye on any potential problems. Short-term concerns, such as rain or clouds obstructing your solar panels, are frequently the reason for lower power generation. However, if these issues persist over an extended period, it may indicate a problem with the panels.

Solar system warranties, fortunately, incorporate a performance guarantee. If your panels are still under warranty, you don’t have to pay to have them repaired if they aren’t producing as much power as they ought to (more on that in the subsequent section).

Replacements and repairs

It’s unusual, but your solar panels may need to be repaired or replaced in some situations. This could happen for a variety of reasons, but the most frequent cause is damage caused by severe weather, like hail, lightning, or falling trees. It’s also possible that faulty panels are to blame.

Most solar panel warranties last for 10 to 25 years after installations, so if you’re still within that time frame, your maker should compensate the cost of repairs resulting from unintentional damaged or defective items. Labor and delivery fees, on the other hand, aren’t always covered by a product warranty. If your warranty has expired, you may have to pay for system repairs yourself.

Other expenses that could arise

There are a couple of additional fees that you may or even may not incur as a solar panel owner, aside from maintenance and repairs. Instead of cleaning your solar panels yourself, you might choose to hire an expert to do it. If this is the case, expect to pay several hundred dollars for every cleaning.
