Expansion and optimisation
Most older systems lose 10–25% of production to shading, poor stringing or ageing inverters. We bring it back.
When is it worth it?
- Consumption has grown (heat pump, EV, pool) and the system is too small
- A chimney, tree or neighbouring building shades part of the roof
- The inverter is 8–10+ years old or has no monitoring
- You want to add a battery to an existing system
Solutions

Frequently asked questions
Can I add panels to an old system?
Yes, but expansion requires a new DSO application and the added part falls under gross metering – we take that into account in sizing.
