Interview with a multi-family complex owner in San Antonio, Texas who installed solar panels with Wells Solar. The interview discusses the unique challenges and opportunities that make commercial solar installations fun, and the financials that make it pencil-out.
Ramesh Mahbubani, "RK" to his friends, was born and raised in North Africa and attended school there, as well as in England and India prior to immigrating to the United States. He graduated from Drake University in Iowa and found his way to San Antonio in 1985 when his wife took a position with the San Antonio Independent School District.
Although knowing very little about renewable energy, RK and his wife decided to install a residential solar power solution on their home. They met with several solar companies in the summer of 2016. After evaluating the proposals, the couple began to appreciate the compelling economic advantages rooftop solar could provide.
They quickly realized solar might also make sense on one of their investment properties, a 20-unit multifamily apartment complex. They chose Wells Solar to install both systems and executed the contract in August. In a series of interviews, we discussed RK's experience with installing a commercial solar system in the San Antonio business environment.
This interview with a multi-family complex owner in San Antonio who installed solar panels with Wells Solar was originally published by Ron Zagarri, TXSES.
Multifamily Property Owner Interview - San Antonio
Ron: When you began this process, how familiar were you with the economic and technical aspects of photovoltaics as it applies to a commercial building?
RK: Not familiar at all. But the process of meeting with several people in the industry has helped me understand it a little. My technical knowledge is still very limited.
Ron: Tell us a little about the system itself. What is the total capacity, the number of panels, and panel type?
RK: The initial proposal was for a 62.44 kW system with 223 Hanwha Q CELLS modules. The expected first-year production was 81,743 kWh. However, the installer chose to use a different, more efficient panel, at the time of install.
Ron: Commercial solar power solutions present some unique challenges and opportunities that we do not typically see in single-family residential systems. Let's first talk about your motivation to even consider this project.
RK: The primary motivation was financial. After experiencing the positive affect solar had on our residential energy bill, we figured we could successfully translate that to a commercial property.
Ron: The apartment complex has a flat roof. How was the system installed to take advantage of that feature?
RK: Due to the flat roof, I did not want any roof penetrations for fear of water leaks. The system is ballasted. We had to work around a lot of HVAC systems and vent piping as you can see in the photos. Also with a ballasted system, it should be easier to temporarily remove a section of the system in the future in case a roof repair is needed.
Ron: How are the panels oriented?
RK: The panels were installed in a bi-directional basis, oriented both east and west. There are no other structures or trees that can create shadowing effects, so this was considered to be the optimal positioning consistent with the roof layout.
Ron: Multi-family residential properties present some unique metering and billing complications in terms of how the solar energy is apportioned to each household. Did you face this issue?
RK: Fortunately, no. One important element that made this particular property a good candidate for solar is that all utilities are included in the apartment rent, so there is just one electric meter and one utility bill that I as the owner pay.
Solar Rebates For Multifamily Properties in San Antonio, Texas
Ron: Let's talk about some of the financial considerations. What was it like working with CPS Energy, the municipal electric provider, and their solar rebate program?
RK: At the time of contracting, CPS was offering a 28 percent rebate, which was later increased to 32 percent. Of course, that is not counting the additional 30% federal tax credit on the balance. So our out of pocket cost ended up at around $60,000. Since this was a business investment, we can depreciate the investment over a very short period of time, approximately five years. The solar panels should be producing for at least 25 years, hopefully as much as 40 years
Ron: How did all that pencil out on a payback period basis?
RK: Our annual pre-solar electricity expenses were about $14,600. In the first post-solar year, our electric bills totaled $11,000 and $10,700 in the second year. If this trend of $11,000 continues, we will realize $3,000 to our bottom line on an annual basis. With the cost of the panels depreciated out after five years this will offer a great added benefit. So the bottom line indicates our payback period will occur in three to four years.
