What is the average cost of inverter replacement for residential solar systems?
The average cost of inverter replacement for residential solar systems typically ranges between £1,000 and £2,500. This cost can vary based on several factors, including the type of inverter, the complexity of the installation, and regional labour rates. Inverters are a crucial component of solar systems, converting the direct current (DC) generated by solar panels into alternating current (AC) for household use.
Regular maintenance and timely replacement of inverters are essential to ensure the optimal performance of your solar system. While the initial investment might seem significant, a well-functioning inverter can enhance the efficiency of your solar panels, ultimately leading to long-term savings on electricity bills.
Inverters are generally expected to last between 10 to 15 years, depending on the brand and usage. When considering replacement, it’s important to weigh the cost against the potential benefits, such as improved efficiency and reliability. Modern inverters often come with advanced features that can further optimise your solar system’s performance.
The type of inverter you choose can significantly impact the replacement cost. String inverters, which are commonly used in residential systems, tend to be less expensive than microinverters or power optimisers. However, microinverters offer the advantage of individual panel monitoring and can be more efficient in certain conditions, albeit at a higher cost.
Labour costs also play a role in the overall expense of inverter replacement. It’s advisable to seek quotes from multiple installers to ensure competitive pricing. Additionally, some solar systems may still be under warranty, which can offset some of the replacement costs. Regular maintenance checks can help identify potential issues early, potentially prolonging the life of your inverter.
