As sustainability becomes a key priority, asset managers are turning to solar energy retrofits across their property portfolios. Yet, deploying solar retrofits on a large scale introduces unique challenges, from thorough site assessments to prioritising projects and ensuring scalability. Adopting a phased approach with a well-structured roadmap can enhance ROI, align projects with budget cycles, and minimise disruptions across multi-asset portfolios. This strategic guide offers insights into phasing solar installations across diverse assets, emphasising crucial steps like prioritisation, site evaluation, and planning for scalable growth.
1. Define Clear Objectives and Assess Portfolio-Wide Goals
Before initiating any retrofitting, it’s critical to establish clear goals. Solar energy can help properties meet net-zero targets, reduce long-term operational costs, and increase property value, but priorities might differ across assets. For example:
- Energy Cost Reduction: Properties with high energy costs may benefit most from an immediate retrofit.
- Sustainability Targets: Assets within municipalities enforcing sustainability regulations could require prioritised attention.
- Tenant Demand and Property Value: Areas with high tenant interest in sustainability often provide an added value for solar investment.
Strategic Insight: By partnering with a solar solutions provider like PowerMarket, which has expertise in multi-asset portfolios, asset managers can set clear objectives and create tailored sustainability strategies that account for regulatory requirements and tenant preferences across different properties.
2. Prioritise Properties Based on Key Metrics
When managing a diverse portfolio, it’s essential to determine which properties should receive retrofits first. Prioritisation enables a phased rollout that respects budget limitations, operational impacts, and location-specific needs. Important factors to consider include:
- Current Energy Usage and Peak Demand: Assets with high energy consumption stand to gain the most from solar, particularly if they have consistent daytime demand.
- Building and Roof Age: Properties with newer roofs may be easier to retrofit and reduce the risk of needing repairs shortly after installation.
- Regulatory Requirements and Incentives: Some jurisdictions offer incentives or subsidies that make retrofits more cost-effective, or even mandate certain environmental standards.
- Tenant Lease Structures: Properties with long-term tenants may benefit most from stable, lower energy costs that support tenant retention.
Efficiency Tip: Leveraging insights from a data-driven solar partner allows for a streamlined analysis of energy use patterns, property conditions, and local incentives. This can help identify the properties with the highest ROI potential, optimising the order of phased installations.
3. Conduct Site Assessments and Feasibility Studies
After prioritising properties, it’s time to assess each site’s solar potential. This involves an in-depth analysis of several factors:
- Solar Irradiance: Measure the solar exposure of each property. Properties with south-facing roofs or open spaces with few obstructions will typically yield higher returns.
- Structural Considerations: Determine if the roof or other structures are fit for the weight and configuration of solar panels. Some assets may require structural upgrades or alternative installation solutions, such as carports or ground-mounted panels.
- Energy Storage Potential: Integrating energy storage may add flexibility and resilience, but it requires both space and budget. Consider storage for properties with high variability in energy usage.
- Grid Connection and Infrastructure: Assess the grid connectivity and the infrastructure’s capacity to handle additional energy loads. Areas with limited grid support might necessitate more complex setups or smaller systems.
Outcome: Use this assessment to create a feasibility report for each property, identifying high-priority, mid-priority, and low-priority locations for solar retrofits. This analysis helps quantify anticipated energy savings and installation costs, ensuring the most impactful investments are prioritised.
4. Plan Phased Installations Based on Portfolio and Budget Cycles
Once the properties are prioritised and assessed, align the rollout with your financial cycles. Phasing installations allows you to maintain flexibility and evaluate the performance of initial installations before scaling. When designing your phases, consider:
- Budget Allocations and ROI Benchmarks: Decide on budget allotments for each phase and establish key performance indicators (KPIs) for ROI. These can include metrics like energy savings, cost reductions, and emission reductions.
- Contractor Selection: Consider a strategic partnership with a single installer across phases to streamline logistics, secure volume discounts, and ensure consistent quality.
- Pilot Programme and Benchmarking: Start with a pilot programme on a smaller subset of high-priority properties. Measure the effectiveness, cost, and ROI, using these results to inform and optimise subsequent phases.
- Flexibility for Future Phases: Include room for adjustments in future phases, based on changes in energy pricing, technology, and regulation. A flexible approach ensures that your retrofit plan can evolve as new innovations in solar tech and storage emerge.
Implementation Insight: Working with an experienced solar coordinator simplifies logistics, streamlines contractor management, and provides financial forecasting support. This ensures each installation phase aligns with financial expectations and has the flexibility to adjust in response to regulatory and technological changes.
5. Focus on Scalability for Long-Term Portfolio Growth
To future-proof a multi-asset solar retrofit, plan for scalability. This involves choosing technologies and partners that can support future expansions, as well as adopting portfolio-wide best practices that simplify future installations. Key considerations include:
- Standardisation: Choose systems and installation processes that can be standardised across the portfolio. This reduces complexity and aids in creating uniform energy reporting and maintenance processes.
- Data-Driven Monitoring: Deploy energy monitoring systems that provide real-time analytics across all retrofitted properties. These systems enable better energy management and help identify which sites are best suited for potential expansions or additional battery storage.
- Staff and Maintenance Training: Solar installations bring new operational needs, so prepare maintenance teams with adequate training to maintain system health and maximise performance.
- Leverage Property Management Software: Integrate the solar retrofit data with existing property management platforms. A cohesive view of solar performance across all assets makes it easier to monitor, adjust, and scale the installations in the future.
Outcome: Scalability not only supports expansion but also creates operational efficiencies, allowing asset managers to manage all installations with greater ease, from a single dashboard or platform.
6. Measure, Optimise, and Plan for Continuous Improvement
After completing each phase of the retrofit, it’s crucial to evaluate its performance against initial KPIs. By consistently tracking solar output, cost savings, and operational impact, asset managers can derive valuable insights that inform future installations. Effective steps for ongoing assessment include:
- Annual Performance Reviews: Compare actual performance with projected savings, adjusting future phases if necessary.
- Feedback from Tenants and Building Staff: Obtain qualitative feedback on operational impacts, which may reveal new opportunities for improvement or highlight benefits for tenant retention.
- Policy Monitoring: Stay updated on local, state, and federal incentives or regulations that could impact the economics of solar retrofits. The policy landscape for renewables is dynamic, and new incentives could accelerate the ROI of future phases.
Example: A mid-phase review might reveal that storage solutions provide additional ROI in high-demand areas, encouraging additional investments in these systems for future properties.
Conclusion
A well-structured, phased approach to solar retrofits enables asset managers to strategically deploy solar across multi-asset portfolios while controlling costs, managing timelines, and meeting sustainability goals.
