A Guide for Properties with Prepayment Meters

‍

Solar energy is a fantastic way to reduce your carbon footprint and save on energy bills. But what happens when you have tenants with prepayment meters like Topupmeters? Can you still install solar photovoltaic (PV) panels and ensure everyone benefits? Absolutely! Here we guide you through the optimal setup for properties with prepayment meters.

‍

The Ideal Configuration

‍

The key is to connect your solar PV system to the property’s electricity supply between the prepayment sub-meters and the primary meter. This configuration offers several advantages:

‍

• Green Energy for Tenants: Tenants receive 100% green energy generated from the solar panels, reducing their reliance on grid-supplied electricity. This can be a strong selling point for potential renters.

‍

• Savings for Landlords: Solar generation offsets the property owner's overall electricity consumption, lowering their energy bills. This includes communal areas and their own usage.

‍

• Maximizing Solar Benefits: By feeding solar energy directly into the main supply, excess power can be exported back to the grid, potentially earning the landlord additional income through government export guarantee scheme.‍

‍

Why Not Install After the Sub-meter?

‍

While it might seem tempting to install the solar PV system on the load side of the prepayment sub-meter, this approach has a significant drawback. If the tenant's credit runs out, the sub-meter will cut off the electricity supply, effectively shutting down the solar PV system. This means:

‍

• No Solar Generation: The system will cease generating electricity, even if the sun is shining.

‍

• No Export to the Grid: Any potential surplus energy that could have been exported for profit is lost.

‍

While this setup would provide tenants with free electricity while the sun shines and they have credit, it's ultimately risky and doesn't maximize the benefits of solar energy for either the landlord or the tenant in the long run.

‍

Important Considerations

‍

• Regulations and Safety: Always ensure your solar PV installation complies with local regulations and safety standards. Consult a qualified electrician for advice and installation.

‍

• Meter Compatibility: Check with your energy supplier and meter provider on the main incoming meter to ensure compatibility with your chosen solar PV system and configuration.

‍

• Tenant Communication: Clearly communicate the benefits of the solar PV system to your tenants, emphasizing their access to green energy.

‍

By carefully planning your solar PV installation and choosing the right configuration, you can create a win-win situation for both landlords and tenants in properties with prepayment meters. Embrace solar energy and contribute to a greener future while enjoying significant cost savings!
