Project Breakdown

We installed a 174 kW solar power system with the objectives of reducing energy costs and grid dependence. With an annual generation capacity of 164,421 kWh, it meets 80,215 kWh of yearly self-consumption needs and exports 84,206 kWh of surplus energy per year.

Hardware

At Sustain Commercial Solar, we prioritise quality and reliability by exclusively using Tier 1 brands and top-notch hardware for our solar installations. This commitment ensures that our systems deliver maximum efficiency, durability, and performance.

For the Porsche solar project, we installed:

  • 431 HTSAAE 405W Monocrystalline Modules

These high-efficiency panels are known for their superior performance and long lifespan, making them a perfect fit for high-demand environments. Additionally, we utilised:

  • 1 x 120kW Solax X3 Inverter
  • 1 x 40kW Solax X3 Inverter

These inverters are renowned for their advanced technology, high efficiency, and robust performance, ensuring optimal conversion of solar energy.

By selecting only the best quality components, Sustain Commercial Solar guarantees that our systems not only meet but exceed industry standards, providing our clients with reliable, long-term solar solutions.

System Monitoring

We have implemented an advanced monitoring system for the Porsche solar project, allowing the client to access real-time data and insights into their energy usage and generation.

This sophisticated monitoring solution is designed to provide comprehensive visibility and control over the solar power system's performance. With user-friendly dashboards and detailed analytics, the client can track live updates on energy production, consumption, and export, ensuring they are always informed about their system's efficiency and output.

If you would like a live link to a public version of the dashboard, please get in touch.
