Quick Answer
Yes, micro-inverters generally come with a higher upfront cost compared to traditional string inverters, with prices ranging from $1 to $3 per watt, whereas string inverters typically cost $0.50 to $1.50 per watt.
Additional Hardware Costs
Micro-inverters require additional hardware, such as mounting clips, cables, and communication devices, which can add 10-20% to the overall system cost. For example, a 7 kW system would require 14-28 micro-inverters, which could add an extra $1,000 to $2,000 to the system cost. These additional components also require more labor to install, which can increase the overall installation cost.
Monitoring and Maintenance Costs
Micro-inverters often come with built-in monitoring and networking capabilities, which can provide real-time system performance data and remote monitoring. While these features can be beneficial for system owners, they also require ongoing subscription fees, which can range from $20 to $50 per month. Additionally, micro-inverters may require more frequent software updates, which can be a hassle for system owners who are not tech-savvy.
