How Solar Optimisers Work – And Why ArchaiPower Delivers Them

Solar optimisers have become one of the most important innovations in solar PV. They promise higher efficiency, improved safety, and smarter control. But do they work as advertised? Independent research from leading institutions worldwide provides the answer — and at ArchaiPower, we turn that insight into practical solutions for our clients.

Why Optimisers Matter

In a standard solar system, panels are wired in a “string.” The entire string performs at the level of the weakest panel. Shade from a tree, dirt on a single module, or natural ageing can reduce the output of the whole system.

Solar optimisers change this. Installed on individual panels, they ensure each module operates at its maximum output regardless of the others. This means your system is no longer held back by its weakest link.

The Technology at Work

Optimisers use module-level Maximum Power Point Tracking (MPPT). Unlike traditional inverters that optimise power at the string level, optimisers do this for every panel:

• Each module generates its maximum possible output.
• Arrays across different roof angles or orientations perform efficiently together.
• Performance can be monitored panel by panel in real time.

What the Evidence Shows

Global studies have confirmed the benefits:

• NREL (USA): Optimisers improve yield by mitigating shading and mismatch losses.
• ZHAW (Switzerland): Found up to 3.5% more energy under shading compared with string inverters.
• IEA-PVPS (2024): Reported clear benefits under partial shading, though gains are smaller in perfectly unshaded sites.
• S&P Global Commodity Insights: Noted growing adoption due to both efficiency and enhanced safety features.
• Tigo Energy (industry data): Reported average 7% more energy across thousands of installations, with gains as high as 17% in shaded systems.

Safety and Compliance

The role of optimisers goes beyond performance:

• Rapid shutdown: Ensures every module can be safely de-energised, protecting installers and first responders.
• Fire and electrical safety compliance: Increasingly a regulatory requirement.
• Smarter diagnostics: Real-time insights to identify and resolve issues quickly.

Where ArchaiPower Adds Value

At ArchaiPower, we don’t just install panels — we deliver systems built to last and perform. Integrating optimisers is part of how we:

• Maximise output: Every panel contributes its full potential, increasing long-term returns.
• Ensure safety: All our systems are designed with compliance and user protection built in.
• Give transparency: Clients get access to panel-level monitoring, so they know their system is performing as it should.
• Future-proof designs: We build for flexibility, making sure systems keep delivering even as conditions change.

The ArchaiPower Approach

Our role is to design solar systems that reflect the real world — where shading, roof layouts, and changing conditions are inevitable. Global studies show optimisers make a measurable difference in these scenarios, and our project experience confirms it.

That’s why ArchaiPower integrates optimisers where they bring the most value: delivering systems that are smarter, safer, and ultimately more profitable for our clients.

Conclusion

Solar optimisers aren’t just about boosting numbers on a datasheet. They are about delivering real-world performance, reliability, and peace of mind.

At ArchaiPower, we combine proven global evidence with hands-on expertise to ensure every solar system we deliver performs at its best — today and long into the future.
