Tesla Powerwall Installation in Conwy Valley – Solar & Battery Storage for Holiday Let

Client Background

The property:  in the Conwy Valley LL32

This detached holiday cottage required:

• Reduced running costs

• Protection from rising electricity prices

• Improved sustainability credentials

• Energy independence during peak tourist seasons

• A premium, future-proof battery system

Holiday lets consume significant energy due to guest turnover, heating, hot water demand and appliance usage — making battery storage essential.

Challenge

• • Annual electricity demand approx. 9,000 kWh

  • Mixed roof orientations

  • Desire for premium, reliable equipment

  • Maximise self-consumption rather than export

  The family wanted a Tesla Powerwall 3 installation to ensure reliability, backup capability and long-term performance.

Site Assessment

After full modelling and performance analysis

We designed:

☀ 9.55kW Solar PV System

• 21 x Jinko Tiger Neo 455W All-Black N-Type panels

• Installed across South West & North East roof elevations

• Designed for optimal generation in North Wales climate

Expected annual generation:
6,743 kWh per year

Installation & Outcome

Solar North completed a full premium solar and Tesla Powerwall installation at this Conwy Valley holiday let, delivering a future-proof renewable energy system designed for performance and reliability.

The installation included:

• A 9.55kW solar PV system using 21 high-efficiency 455W all-black Jinko panels

• Tesla Powerwall 3 with 13.5kWh battery storage

• Tesla Backup Gateway integration

• Full system commissioning and certification

The solar panels were installed across multiple roof elevations to maximise generation throughout the day, taking into account orientation and shading. The Tesla Powerwall 3 was carefully positioned for optimal performance, seamless integration, and long-term reliability.

All work was carried out by Solar North’s qualified in-house team, ensuring full MCS compliance and Tesla installation standards. The installation was completed efficiently with minimal disruption to the holiday let schedule.

As experienced Tesla Powerwall installers serving North Wales and Cheshire, we ensured a clean finish and a system built to last.

Outcome

The results were immediate and significant.

The system is expected to generate approximately 6,743 kWh per year, supplying a large proportion of the property’s annual electricity demand.

With the Tesla Powerwall installed, solar self-consumption increased substantially, reducing grid dependence to around 46% and delivering up to 54% energy independence.

The owners can now expect:

• Estimated first-year savings of around £1,588

• Significantly reduced exposure to rising energy prices

• Lower operating costs for the holiday let

• Improved environmental performance

• Annual CO₂ savings of over 1,300kg

For anyone searching for a Tesla Powerwall installer in North Wales or Cheshire, this project demonstrates how Solar North delivers premium solar and battery systems designed for performance, savings, and energy independence.
