As a landlord, making smart, long-term investments in your properties is key to maximizing returns and maintaining a competitive edge in the rental market. One of the most forward-thinking upgrades you can make is installing solar panels on rental homes. Not only can this help reduce energy costs for your tenants, but it also makes your property more attractive and environmentally friendly. But how do you calculate the return on investment (ROI) for houses with solar panels? Here's a step-by-step guide to help you determine if the investment is worth it.

1. Understand the Costs of Installing Solar Panels

The first step in calculating ROI is determining the upfront costs of installing solar panels. These costs typically include:

  • Solar panel system : The price of the panels themselves can vary depending on the size and brand.
  • Installation fees: Professional installation is a must, and prices depend on the complexity of the job.
  • Permitting and inspections: Some areas require permits and inspections before and after installation, which can add to the overall cost.
  • Maintenance costs : While solar panels require minimal maintenance, there might still be occasional cleaning and repairs to factor in.

On average, solar panel systems for homes can cost anywhere from $10,000 to $30,000 or more, depending on the size of the system and the location. Be sure to get a detailed estimate from a solar provider to understand your exact investment.

2. Calculate the Energy Savings

One of the main benefits of installing solar panels is the reduction in energy costs. To estimate how much you'll save, you need to know:

  • Average monthly electricity usage: Look at the electricity consumption of the house per month or year. Your tenants' energy usage will largely depend on the number of people living in the house and how energy-efficient the home is.
  • Size of the solar panel system: The larger the system, the more electricity it can generate, and the greater your potential savings.
  • Energy savings per month : Once you've determined the potential energy output of the system, you can calculate the monthly savings. For instance, if your solar system covers 80% of the property's energy needs, you would reduce the tenant's monthly utility bills by that percentage.

On average, solar panels can save homeowners between $100 to $200 per month on energy costs, depending on the system size and energy usage. Multiply this savings by the number of months your tenants stay in the property to calculate the annual savings.

3. Consider Potential Rent Increases

Another way to calculate ROI is to consider whether the solar panels allow you to increase your rent. Many tenants are willing to pay more for homes with solar panels because of the energy savings they provide. The added value is especially appealing in markets where electricity costs are high.

You'll need to research how much rent you can increase and what tenants in your area are willing to pay for homes with solar energy. In some markets, a solar-equipped home can demand a rent premium of 5% to 15% above the typical market rate. For instance, if your monthly rent is $1,500, a 10% rent increase could add an extra $150 per month, or $1,800 per year.

4. Take Advantage of Tax Incentives and Rebates

Many governments offer tax incentives, rebates, and credits to encourage the use of renewable energy. In the U.S., for example, the federal government offers a Solar Investment Tax Credit (ITC), which can reduce installation costs by up to 30%. Local and state governments may also have additional incentives.

To calculate ROI, factor these savings into the upfront cost of the solar panel system. For example, if your system costs $20,000 and you qualify for a 30% federal tax credit, your cost would be reduced by $6,000, bringing the total investment down to $14,000.

5. Factor in Long-Term Maintenance Costs

Although solar panels are low-maintenance, they're not maintenance-free. Over time, you may need to replace parts, repair the system, or clean the panels. Typically, solar panels last 25 years or more, but parts such as inverters may need replacement every 10 to 15 years.

Estimate the long-term maintenance costs, such as:

  • System cleaning and inspection : Cleaning the panels every 6 months or as needed.
  • Inverter replacement : Inverters typically need to be replaced every 10 to 15 years.
  • Repair costs: These can vary depending on the system's performance and the weather conditions.

Include an estimated annual maintenance cost in your ROI calculation to get a more accurate picture of your investment.

6. Estimate the Payback Period

The payback period is the time it takes for the energy savings and potential rent increase to offset the initial cost of the solar panels. To calculate this, divide the total cost of the solar system by the annual savings (energy savings + rent increase). For example, if the system costs $15,000 and you're saving $2,000 annually through energy savings and rent increase, the payback period would be 7.5 years ($15,000 รท $2,000 = 7.5 years).

7. Calculate Long-Term ROI

To calculate long-term ROI, you need to estimate how much you'll earn from energy savings and rent increases over the life of the solar system. Using the same example, if the system lasts 25 years, you would earn $2,000 annually for 25 years, which totals $50,000. Subtract the initial investment of $15,000 and the maintenance costs over the years to get your net gain.

Long-term ROI is a great way to evaluate the financial benefits of solar panels because it reflects both the ongoing savings and the potential for long-term asset appreciation.

8. Assess Property Value Appreciation

Lastly, solar panels can increase the overall value of your rental property. Homes with solar energy systems tend to sell for higher prices and are more appealing to buyers looking for energy-efficient homes. Even though this may not immediately affect your rental income, it's a significant factor to consider if you plan to sell the property in the future.

Studies show that homes with solar panels can sell for anywhere from 3% to 4% more than comparable homes without solar systems. This can be a considerable increase in property value, making solar panels a valuable long-term investment.

Conclusion

Calculating the ROI of houses with solar panels requires a comprehensive understanding of upfront costs, energy savings, potential rent increases, tax incentives, and long-term value. While the initial investment can be significant, the benefits of reduced energy bills, higher rent, and improved property value make it a wise decision for many landlords. By carefully considering all the factors and calculating the potential savings, you can determine whether installing solar panels on your rental property is a good investment that will pay off in both the short and long term.
