McGuinness Renewables installs advanced solar battery storage systems and provides expert guidance on selling excess solar electricity back to the grid.

Serving homes and businesses across North Wales, Wrexham, and the wider UK, we help you make informed decisions that support energy independence and long-term savings.

What is Solar Battery Storage?

Solar battery storage allows you to store the energy generated by your solar PV system during the day for use at night or during peak tariff periods.

When combined with a SmartGrid-ready setup, you can also export unused energy to the grid and receive payments through schemes like the Smart Export Guarantee (SEG).

What We Offer

Pros & Cons of Solar Battery Storage Systems

Pros

  • Lower Energy Bills
    Use more of your self-generated energy and rely less on expensive grid electricity.
  • Greater Energy Independence
    Stay powered during outages or grid failures.
  • Grid Flexibility
    Store off-peak or surplus solar power for use when you need it most.
  • Environmental Impact
    Further reduce your carbon footprint by using clean energy day and night.
  • Compatible with New or Existing Solar PV Systems
    Retrofit battery options available.

Cons

  • Upfront Cost
    Battery systems represent a significant initial investment.
  • Longer ROI Period
    Payback times may be longer than for solar PV alone, depending on usage patterns.
  • Limited Capacity
    Some systems may not cover your full overnight or peak usage without additional storage.

We help clients in North Wales, Wrexham, and UK-wide assess whether a battery system is right for their property or usage patterns, and how best to scale it.

Selling Solar Electricity Back to the Grid – Is It Worth It?

Thanks to the SEG scheme, you can now earn money for exporting unused solar electricity back to the grid.

Grid Export Benefits

  • Monetise Surplus Power
    Get paid for energy you don’t use.
  • Fast Payback When Usage Is Low
    Ideal for businesses closed at weekends or homes unoccupied during the day.
  • Clean Energy Contribution
    Help reduce demand on fossil fuel power sources.

Considerations

  • SEG Rates Vary by Supplier
    Some providers offer higher export rates than others – we’ll help you compare.
  • You Still Need a Battery to Maximise Use
    Without storage, you only benefit during active generation hours.
  • Usage Profile Matters
    Export is more beneficial if your property doesn’t use much power during the day.
