The most profitable property upgrades often hide in plain sight. For many owners and managers, solar panels and electric vehicle (EV) charging stations may feel like futuristic add-ons rather than immediate necessities. Yet the reality is that these improvements can significantly boost property value, attract higher-quality tenants, and reduce long-term operating costs. The challenge lies in projecting the return on investment (ROI) with accuracy and confidence.

Why ROI for Energy Efficiency Is Tricky to Calculate

Unlike a straightforward rent increase, the ROI on energy-efficient upgrades has multiple moving parts. The payback depends on:

• Local energy costs: Higher utility rates mean greater savings from solar.

• Regulatory incentives: Tax credits, rebates, and utility subsidies can dramatically shorten payback periods.

• Tenant demand: EV charging stations may generate little value in areas with low adoption, but in urban hubs, they can be decisive in tenant retention.

• Property type: Multifamily buildings, office complexes, and retail spaces all see different utilization patterns that impact ROI.

Ignoring these nuances can lead to inflated expectations—or worse, missed opportunities.

Solar Panels: A Case of Predictable Returns

Solar panels tend to deliver more predictable ROI compared to other upgrades. Savings on electricity bills are measurable and usually rise over time as utility costs increase. According to the U.S. Department of Energy, commercial properties often see payback periods between 5 and 10 years, depending on location and incentives.

For example, a 50,000-square-foot office building in California could install solar panels that offset 60 percent of its electricity use. With state rebates and federal tax credits, the project might pay for itself in seven years, while also boosting the property’s market valuation.

However, in regions with low sunlight or inexpensive electricity, the timeline could stretch to 12 years or more. That gap underscores the importance of modeling assumptions around local energy pricing and usage.

EV Charging: A Value Play, Not Just a Cost Play

EV charging stations are less about direct cost savings and more about enhancing tenant experience and property competitiveness. Multifamily buildings with chargers can justify higher rents, while commercial properties may attract corporate tenants looking to meet sustainability goals.

ROI here is less about simple payback and more about capturing value through:

• Higher tenant retention: Residents or employees with EVs are less likely to leave if charging is available on-site.

• Increased leasing velocity: Properties may lease faster when marketed as sustainable and future-ready.

• Potential revenue streams: Owners can choose to bill per charging session, offsetting installation costs.

The challenge is timing. In regions where EV adoption is still low, chargers may sit idle. Yet in markets like California, New York, or Washington, demand is rising so quickly that not having chargers can become a competitive disadvantage.

How to Model ROI Effectively

Property managers can use a three-part framework when evaluating upgrades:

1. Baseline analysis: Measure current energy costs, tenant turnover, and leasing velocity.

2. Scenario modeling: Project savings or revenue streams under different adoption rates and energy pricing forecasts.

3. Risk adjustment: Factor in uncertainties like fluctuating utility incentives, future regulations, or technology costs.

This approach not only sharpens financial estimates but also prepares owners for contingencies that could either accelerate or slow down payback.

The Bigger Picture: Beyond Numbers

Projecting ROI is critical, but energy-efficient upgrades also deliver intangible returns that are harder to model yet highly influential. These include improved brand reputation, alignment with ESG (environmental, social, and governance) standards, and increased resilience against future regulatory changes.

In many cases, these “soft benefits” translate indirectly into higher asset valuations and stronger tenant loyalty. Ignoring them risks undervaluing the true payoff of solar panels, EV charging, and other green investments.
