Solar Panels at Home – How to Prepare Your Electrical Installation?

The decision to install solar panels usually comes at the finishing stage – which is a mistake. A well-designed photovoltaic installation requires adequate space in the distribution board and pre-installed cabling. This way, panel installation will be quick, cheaper, and non-invasive to the facade.

What to Plan for a PV Installation?

• Cable route from distribution board to inverter mounting location,
• Conduit for DC cables from the roof,
• Free modules in distribution board for protection devices,
• Dedicated circuit for inverter and energy metering.

What Protections Are Required?

A PV installation must meet AC/DC protection standards:

• Type 1/2 DC SPD – surge protection,
• AC SPD in distribution board,
• Type A or B RCD for inverter,
• Overcurrent breaker + PV isolation switch.

Inverter Mounting Location

Best locations are garage, utility room, or plant room – cool, dry, with good ventilation. Inverters don't like high temperatures.

If you prepare the installation in advance – PV installation will be quick, neat, and without unnecessary wall chasing.
