Solar + Brightbox™

Add Brightbox, Sunrun's battery storage system, to your solar installation in Diamond Bar. This can help keep you powered during outages, cloudy days, rainy afternoons, at night, or during Time-of-Use (TOU) rate spikes.9

Climate change and utility neglect have made wildfires and related outages more common across the Golden State.

Electric companies are rolling out Public Safety Power Shutoffs (PSPS), which leave homes without electricity for hours or days at a time.

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 and affordable back-up energy for later use.

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

No fuel, no fumes, no noise, no hassle. Brightbox is a superior back-up energy solution compared to loud and dirty generators.

You can monitor your Diamond Bar solar power production and storage daily with the online dashboard and mobile app.

All monthly plans include 24/7 proactive monitoring and maintenance to ensure your home solar energy system runs smoothly. This perk sets Brightbox apart from other solar batteries in Diamond Bar.
