THE PROJECT:

RSE had been operating with a 10-year-old solar PV system that increasingly exhibited performance issues. Despite initial energy savings, the aging system struggled with efficiency, which led to higher operational costs and frequent maintenance.

RSE’s original solar PV system, installed in 2013, was once a modern solution that helped reduce energy costs and supported the company’s sustainability goals. However, over the years, the system’s performance deteriorated, with its characteristics becoming outdated and wear and tear causing decrease in reliability. With issues such as frequent earth faults, inverter failures, reduced energy output and high maintenance costs hampering the overall performance.

THE WORKS:

After thorough analysis, RSE decided to upgrade to a new solar PV system. Taking into account a range of factors, alongside support from the specialist team at RI Cruden, the below key considerations were discussed:

  • Technological Advancements: Modern solar panels and inverters offer significantly higher efficiency and reliability.
  • Cost Savings: Projected energy savings and reduced maintenance costs would offset the initial investment.
  • Sustainability Goals: A new system would better align with the company’s long-term sustainability objectives.
  • Existing Feed In Tariff: the original system was installed with a Feed In Tariff (FIT). This tariff is transferable to the new system and with this added benefit the payback period was less than 5 years.
  • Existing Grid Connection: Due to the existing grid connection no waiting time was required as DNO authorisation was already in place.

 

RI Cruden provided a complete solution including the following;

  • New design using much fewer panels due to increased panel performance.
  • Removal and recycling of existing panels.
  • Cleaning the roof from years of debris build up.
  • Supply, install and commission new Solar Edge solar system with 20-year extended warranty.

OVERALL RESULTS:

Since the upgrade, RSE has experienced significant improvements:

  • Increased Energy Output: The new system generates 25% more energy compared to the old system, significantly lowering electricity bills.
  • Enhanced Reliability: The new system’s reliability has ensured continuous operation, reducing the risk of production delays.
  • Return on Investment: The initial investment in the new system is projected to be recouped within 4.6 years, thanks to energy savings and available incentives.
  • Environmental Impact: The enhanced efficiency contributes to a 30% reduction in the company’s carbon footprint, supporting their sustainability commitments.

By replacing the outdated system, RSE not only resolved performance issues but also achieved substantial cost savings, improved operational reliability, and reinforced their commitment to sustainability. This case underscores the value of upgrading aging solar infrastructure to leverage advancements in technology and maximise financial and environmental benefits.
