Case Study: Cold Harbour Police Station Solar Energy Solution

Case Study: Cold Harbour Police Station Solar Energy Solution

Client: Kent Police
Location: Maidstone

Overview: Cold Harbour Police Station, operated by Kent Police, faced a pressing challenge due to the continuous escalation of energy costs and uncertainties surrounding future energy market conditions. To address these issues, the police station sought an energy-efficient solution that would not only reduce their operational expenses but also enhance security and sustainability.

Problem: Kent Police's Cold Harbour Police Station was experiencing a significant increase in energy bills, posing a financial burden on their operations. Additionally, the unpredictability of future energy conditions added to their concerns, necessitating a proactive approach.

Solution: After a comprehensive assessment, Kent Police opted to implement a 120-panel solar energy solution, complemented by 120 micro-inverters. The choice of micro-inverters was made to maximize on-site security. Micro-inverters convert DC power to AC instantly, eliminating the safety risks associated with high-voltage DC electricity. They also come with a 25-year warranty, in contrast to the 5-year warranties of string inverters. Micro-inverters undergo rigorous testing to withstand extreme weather conditions, making them an ideal choice for a police station.

Key Figures:

• Array Size: 60 kW solar panel system
• Daily Peak Output: 273 kWh
• Lifetime Yield: 3.86 MWh
• Estimated ROI: 3 years and 10 months*
• Installation Time: 4 days

Results:

1. Reduction of Carbon Footprint: The installation of the 120-panel solar solution immediately led to a substantial reduction in Cold Harbour Police Station #3's carbon footprint, aligning with their sustainability objectives.

2. Increased Security: The use of micro-inverters significantly enhanced on-site security compared to a string inverter solution. Micro-inverters' ability to convert DC power to AC instantly eliminated potential safety risks associated with high-voltage DC electricity.

3. Energy Savings: The solar panel system provided considerable energy savings, effectively reducing the station's monthly energy bills, and alleviating financial pressure.

4. Future-Proofed Business: Kent Police ensured the station's resilience against potential energy market fluctuations, positioning them as a forward-thinking and adaptable organization.

5. Infrastructure for Expansion: The installed solar infrastructure provided flexibility for future expansion, allowing for the addition of more panels or batteries as needed.

6. Green Credentials: The police station's dedication to sustainability and environmentally responsible practices was further solidified, reinforcing their commitment to green initiatives.

7. Satisfied Client: Kent Police expressed satisfaction with the results, emphasizing the immediate and tangible benefits of the solar energy solution with micro-inverters.

*Note: ROI figures are projections and will be verified after a minimum operating period.

Conclusion: Kent Police's Cold Harbour Police Station's decision to implement a 120-panel solar energy solution with 120 micro-inverters not only addressed their immediate energy cost concerns but also enhanced security and positioned them as a sustainable and resilient organization. This case study exemplifies how the adoption of renewable energy solutions, coupled with innovative technologies, can deliver substantial financial benefits while reducing carbon emissions and ensuring the safety of critical infrastructure.
