A Realtor's Guide To Listing A Property With Solar.

As a real estate agent, you have probably come across property listings with a solar energy system.  Whether you are representing the buyer, the seller, or acting as a dual agent, you will need to know the specifics about that solar system.  Are you prepared to discuss the pros and cons of solar ownership and solar leases with your clients?  Do you know if the solar system is an asset or liability?  Do you know how to capture the value that solar photovoltaic (PV) systems add to the transaction?  This simple guide is designed to help you navigate the complexities of real estate listings with solar.

A Realtor’s Guide to Property Listings with a Solar System. 

Step 1: Find Out If The Solar System is Owned, leased, or a Power Purchase Agreement
The first step in the process is to understand the differences between solar ownership and solar leasing or power purchase agreements.  There are substantial differences in the value of the property depending on whether the solar system is owned, financed, or leased with a power purchase agreement.

Solar Ownership

Solar ownership is when the property owner buys the solar system using either cash or financing.  Once paid for, they own the solar system.  There are several financial incentives that favor solar ownership including:

  • 30% federal investment tax credit
  • Depreciation for commercial solar systems
  • State and local grants are available in certain areas
  • Solar Renewal Energy Certificates (SRECs)
  • Reduction or elimination of energy costs
  • Increased property value

When you purchase a solar system, you get a federal tax credit equal to 30% of the purchase price.  This is a dollar-for-dollar tax credit with the flexibility to carry it forward if you can’t use it in the current year.  In addition to the federal tax credit, businesses can depreciate the solar system giving them additional tax savings.  SRECs have the potential to be an ongoing revenue stream for the owner of those credits.   SREC markets are not available in all states, and SREC values fluctuate based on supply and demand.  One of the great benefits of solar ownership is the increase in property value.  According to a 2011 study by the National Bureau of Economic Research (NBER), the average solar energy system added 3% to 4% or approximately $22,500 to the average home’s value.   Another study by the Lawrence Berkely National Laboratory concluded that “home buyers consistently have been willing to pay more for a property with PV across a variety of states, housing and PV markets, and home types.  Average market premiums across the full sample of homes analyzed here are about $4/W or $15,000 for an average-sized 3.6kW PV system.”   See figure 1.1 below.  While there is a slight variance between the two studies, there’s no doubt that solar ownership increases the value of a property, and that buyers are willing to pay more homes with solar ownership.  As a general rule of thumb, solar increases the property value by the net cost of the solar system (total purchase price minus the incentives).

If you have a listing where the solar is owned, free and clear of loans and/or financing then the solar system is an asset to the transaction for the following reasons:

  • Reduced or no electric bill
  • Lower carbon footprint
  • Potential SREC income for the buyer
  • Increased property value

Power Purchase Agreements (PPAs) and Long Term Leases

Leases and PPAs have been attractive to solar buyers primarily because they allow the property owners to go solar with little or no money down.  A third party pays for and owns the solar system, and in turn, sells the electricity to the property owner at a pre-determined rate.  They usually have an attractive introductory rate equal to, or in some cases, even less than their current electric rate.  This is attractive up front, but they almost always include inflation escalators equal to or higher than the actual inflation of electric rates.  Furthermore, these agreements are usually long-term agreements ranging from 20 to 30 years.  As a result, these agreements are beneficial in the early years of the agreement but have the potential to be more expensive later on.  If you are listing a property with a power purchase agreement or a lease, you will need to either, find a buyer that is willing to assume that agreement or have the seller buy out of the agreement before listing the property.  Both of these scenarios make listing a property with a power purchase agreement or a lease more challenging.  Unfortunately, leases and power purchase agreements very seldom add any value to the property.  For the most part, they are detrimental to the transaction.

Step 2: Determine The System Size, Production, and Savings

The next step in the process is to determine the size of the system, the production of the system, and the savings from the system.  For this particular step, we recommend using the Listing A Property With Solar Worksheet.  The best way to capture this data is from the paperwork received from the company that installed the solar system.  The original solar installer should have included the size of the system, the projected annual production in kilowatt hours, as well as the avoided cost of electricity per kilowatt hour.  If this information is unavailable, you can calculate the size of the system by multiplying the amount of solar panels by the wattage of each panel.  For example, a solar system with 30 panels that are 300 watts per panel will be a (30 x 300 = 9,000) 9,000 watts or a 9 kilowatt system.  The next step in would be to calculate the annual production of the solar system.  There are many variables that go into calculating production such as the amount of shade, the orientation of the solar panels, the tilt of the roof, etc. which make calculating the production more challenging.  As a general rule of thumb, assuming little to no shade, the solar system will generate approximately 120% of the total watts of the system.  For example, a 9,000 watt system would generate approximately 10,800 kilowatt hours (kWh) per year.  Once you know the projected annual production, it is relatively easy to calculate the annual savings by multiplying the kilowatt hours by the avoided cost of electricity.  For example, 10,800 kWh X $0.14 = $1,512 in annual savings.

Step 3: Write Your Listing

The third and final step in the process is to make sure that you have the correct messaging in your listing to make sure that potential buyers have a complete understanding of the solar system.  Here is the recommended message:

Solar Ownership Messaging

This property includes a 9 kW solar system that generates over 10,000 kilowatt hours per year.  The utility bill for this house is $12 per month.  This solar system saves the owner approximately $1,500 per year.  The solar system is still under warranty and all warranties transfer to the new owner.

Summary

If the solar system is under a power purchase agreement or lease agreement it is likely that the system does not add value to the property.  Furthermore, PPA or lease agreements will also add challenges to the transactions including finding a buyer that will assume the agreement along with increased costs.  Solar ownership, on the other hand, increases the property value, lowers the utility bills, and could help you sell the property more expeditiously.
