Around 200 solar panels have been installed by Borders College and Heriot-Watt University at their shared Borders College Campus in Galashiels.
The installation is the largest of its type in the Scottish Borders.
The project is one of many being undertaken by the Campus, in a bid to lower their CO2 emissions.
The new panels are expected to produce over 42,000 kilowatt hours of electricity every year, which will reduce electricity costs and cut consumption by around 4%.
The panels are expected to continue to produce electricity for up to 40 years.
"This development demonstrates Borders College's continuing commitment to environmental sustainability and is one of a range of measures that the College is taking to reduce its carbon emissions.
"More than that, it is an excellent example of how the partnership with Heriot-Watt University continues to support an efficient and sustainable further and higher education campus in the Scottish Borders."
