Community Service


On November 2, 2018 esVolta teamed up with GRID Alternatives GLA to bring renewable energy technology to an underserved community in Long Beach, California.

With the help of our friends from GRID Alternatives GLA, we installed a 2.24 kw-dc solar system on a small single-family home, which is projected to have the following environmental and economic impacts for the family and the community:

  • $8,035 of savings over the system’s lifetime of 20 years

  • 25 tons of emissions reduced

    • Equivalent to planting about 583 trees

    • Equivalent to taking 4.8 cars off the road

Overall, a great day of teamwork, learning and social contribution!
