More than four million Texans were left without electricity for days.4 In San Antonio, Texas, Winter Storm Uri was unlike anything seen in over 30 years.5 The temperatures fell to 6 °F (-14 °C)5 and left 300,000 San Antonians in the dark without heat.6 

Snowstorm Uri’s deep-freeze disaster also caused electricity prices to spike more than 10,000%.7 Now with Sunrun’s solar and battery storage solutions, you have the chance to put a stop to the uncertainty.

Solar + Brightbox™

Add Brightbox, Sunrun’s battery storage service, to your solar installation in San Antonio. This can help keep your devices and appliances running during outages, cloudy days, rainy afternoons, or at night.

High demand for electricity in summer and winter, paired with unpredictable weather, have put Texas at a higher risk of blackouts—like the major impacts caused by back-to-back winter storms, Uri and Viola.14​

To protect the whole grid from going down during snowstorms, The Electric Reliability Council of Texas (ERCOT) imposed rolling blackouts. These blackouts left millions of homes without electricity for days.15,16

Brightbox can help you back up your entire home with a Tesla Powerwall, or you can back up just the rooms you need with an LG Chem solar battery.**

When the sun is out, Brightbox can store clean, safe, and affordable backup power for later use.

Brightbox is the San Antonio battery storage solution that puts you in control. It can turn on during an outage and will work to recharge until the grid's restored.

Unlike generators, Brightbox doesn’t run on fossil fuels, which produce carbon monoxide (CO) that’s poisonous and dangerous for your health.17,18​

Brightbox is fueled by the sun, so you can forget about the hassle of buying expensive gas and diesel. You can even monitor your San Antonio solar energy production and storage daily with the online dashboard and mobile app.

With an energy storage solution like Brightbox, electricity is as reliable and local as you can get.
