System Upgrades & Extensions

Get More From Your Existing Solar Installation

Your electricity usage may have changed since your solar system was first installed. You may now have an electric vehicle, heat pump, battery or higher daytime electricity demand.

Solar Support assesses existing installations and identifies practical ways to increase generation, storage capacity, visibility or overall system performance.

Solar Upgrade Options

Depending on the existing installation, upgrades may include:

Adding More Solar Panels

Before extending an existing array, we assess:

1
Available roof space
2
Roof orientation and shading
3
Existing panel specifications
4
Inverter capacity and voltage limits
5
Electrical and cable capacity
6
Mounting-system compatibility
7
Grid-connection requirements
8
Whether matching panels are still available

Newer panels may have different electrical characteristics from the original equipment, so they cannot always be added directly to the same string.

Upgrading to a Hybrid Inverter

Many older solar installations use a standard string inverter that was not designed to operate with a battery.

Replacing it with a battery-ready hybrid inverter may make it possible to:

The existing panels, strings, cabling and electrical protection must be checked before an inverter is replaced.

Adding More Battery Capacity

If you already have a battery, additional capacity may be possible. However, battery expansion depends on:

Some manufacturers restrict the mixing of batteries of different ages, capacities or generations. Compatibility must be confirmed before additional modules are ordered.

Start With a System Assessment

Before proposing an upgrade, we review what is already installed and how it is performing. We then compare the available options and explain whether the proposed upgrade is practical.

Where appropriate, we will also advise whether repairing the existing system, replacing individual components or installing a separately managed extension would provide better value.

Planning an Upgrade?

Send us photographs of your inverter, panels, meter and consumer unit, together with a recent electricity bill. We will review the existing installation and recommend the next step.
