Enhancing Solar PV Systems through Inverter Repowering

As solar PV systems age, repowering—upgrading or replacing inverters—has become crucial for optimizing energy yield, ensuring compliance, and integrating advanced features. Solis and partners are leading this initiative by offering innovative inverter solutions for residential and commercial solar installations.

Why Repowering Matters Repowering addresses efficiency decline, outdated technology, and evolving regulatory standards in older PV systems. Key drivers include:

• A sharp rise in aging systems, with 700 GW of 10+ year-old PV capacity projected by 2030.

• Inverter failures due to harsh environments or discontinued support.

• Stricter regulations like BS 7671 and IEC 62446 requiring modern compliance.

• New inverter designs offering better grid integration and monitoring capabilities.

Tailored Solutions and Risk Mitigation Solis emphasizes proactive repowering to avoid downtime and extend system life. Their approach:

• Enhances reliability with inverters designed to IEC 62093 standards.

• Supports smart-home integration and energy storage compatibility for residential users.

• Minimizes business disruption in commercial projects through meticulous planning and stakeholder coordination.

Technology-Driven Repowering Trends Solis and installers like Forniture Sim Srl showcase how technological upgrades boost performance. One project reported:

• Integration of bifacial modules and modern inverters. • 10% prior efficiency loss recovered and a 20% increase in power output.

• Continued performance and strong service support from Solis.

The Future of Repowering With rising adoption of smart grids and decentralized systems, repowering will be essential for:

• Enabling microgrids and demand response programs.

• Unlocking new business models through smart energy management.

• Ensuring long-term system value with superior service and local support.

Solis’ comprehensive repowering offerings empower PV system owners to boost efficiency, adapt to change, and contribute to a more sustainable energy future.
