What is a solar power optimiser?
A solar optimiser, also known as a power optimiser for solar panels, is a module-level power electronic device installed on the DC side between an individual solar panel and a compatible central inverter.
Attached to each panel, these DC-to-DC converters perform Maximum Power Point Tracking (MPPT) at module level and condition the panel’s DC output to support overall system performance.
This allows each panel to operate independently while still feeding into a single central inverter, helping maximise energy harvest in systems affected by shading, different roof orientations, soiling or module mismatch.
Benefits of power optimisers
Enhanced energy yield
- Each PV panel optimiser independently maximises its module’s output, helping reduce losses under shading or uneven operating conditions.
- Design flexibility
- Optimisers can support uneven rooftops, multiple orientations and partially shaded arrays, allowing greater flexibility in PV system design.
- Rapid shutdown support
- Selected optimiser systems support module-level rapid shutdown for maintenance and emergency situations.
- Real-time monitoring
- Compatible systems can provide panel-level performance data, supporting fault detection, remote diagnostics and proactive maintenance.
- Improved long-term performance
- Optimisers help reduce losses caused by shading, module mismatch and soiling, while panel-level monitoring can help identify underperforming modules earlier.
- Compatible with central inverters
- Power optimisers provide module-level optimisation while retaining a compatible central inverter, balancing performance, monitoring and cost efficiency.
