Marble Falls high goes solar for long-term savings

Marble Falls Independent School District officials like to take advantage of the sunny side of things.

In fact, the school district made a nearly $2 million investment aimed at capturing the sun’s rays and turning it into energy.

More than 950 panels, or solar modules, were installed at Marble Falls High School over the summer on rooftops over the auditorium, Fine Arts wing and 400 and 300 hallways, on the south end of the main building.

According to documents., the project includes “a 565.8 kW DC solar array comprised of

959 photovoltaic modules, 959 power optimizers, and four SolarEdge 120 kW inverters,

creating a distributed energy resource integrated directly into the high school’s existing

facilities.”

Marble Falls ISD spokeswoman Lauren Jette offered insight about the installation which promises to translate into savings.

“By utilizing solar power on existing structures, we should see some yearly savings on the high school’s utility costs,” she said. “Solar won’t completely power the whole campus, but it will make a dent in the bill, and allow that savings to be used in another capacity.”

Funding for the system was included in the 2025 Bond approved by voters (Prop A). The board approved $1,948,491 towards the cost  in January 2026.

Jette says, “School districts across Texas are continually looking for ways to maximize the value of their facilities while planning for the future. 

“At Marble Falls High School, that opportunity was found above the students and staff who use the building every day. “

Officials consider the finished product “ ….a long-term energy asset for the district, existing facilities can be leveraged to support operational goals without expanding the campus footprint.”

Jette said, “By utilizing available rooftop space, Marble Falls ISD is making an investment that supports both facility performance and long-term stewardship of district resources.”
