Post-installation costs to plan for
While solar systems have low routine costs, there are some ongoing expenses homeowners should expect over the system’s lifetime.
Typical ongoing costs:
- Inverter replacement: Inverters often need replacement after 10–15 years; budget for this mid-life cost.
- Maintenance and cleaning: Occasional cleaning, vegetation control for ground systems, and periodic professional inspections.
- Monitoring subscription fees: Some advanced monitoring platforms have optional subscription costs.
- Insurance: Check home insurance premiums—adding solar may slightly change rates.
Less frequent or contingent costs
- Panel repairs or replacement in the rare event of damage from storms or hail
- Battery replacement and maintenance if a storage system is installed
Saving strategies
- Regular preventive maintenance reduces the likelihood of major repairs.
- Choose quality equipment and reputable installers to minimize warranty claims and service needs.
Budgeting for these costs ensures you aren’t surprised mid-life and can help calculate realistic lifetime economics.
