AUSTIN, Texas (AP) The installation of a natural gas monitor in the home of a Houston resident has helped boost the city’s natural gas supply and cut carbon emissions.

The Austin-based company installed the $7,500 solar panel last month and says it’s now the nation’s largest.

It also has installed panels on a second-floor balcony.

The company says the panels can monitor natural gas for more than two years.

It’s installed solar panels on the second floor of a house in Houston that has a natural-gas detector and monitor system.
