What is the maintenance cost of a solar system?
Our water drain-back thermal systems are designed for very low maintenance. Over the span of 25 years, to the best of our knowledge, our customers require an average maintenance of less than $50 per year. Thermal systems installed in the early 80s with poor design can be quite costly to maintain. This is why we recommend to our service customers to consider upgrading to a water drain-back system while the federal tax credit is available. Electric systems also typically require very little maintenance, and customers experience an average maintenance cost of less than $50 per year over the long run. Maintenance needs usually occur once every 10 to 20 years. A pump ($100 to $400) or sensor ($25) can require replacement in a thermal system. Electric systems can require replacing AC/DC inverter ($2,500 to $3,500).
