Battery = Storage

HOEPER GREEN POWEREnvironmentally Friendly Building Solutions

Why do we need storage?

Why Energy Storage ?

o I want to reduce my utility costs

o I often experience power outages

o I want to be more energy independent

o I want to have reliable power off the grid

o I want to be prepared against natural disasters

o My electricity provider makes it difficult to go solar

Common uses for storage:

-Off Grid

-Backup Power-Reducing Peak Demand Charges

-Self Consumption

HOEPER GREEN POWEREnvironmentally Friendly Building Solutions

Storage becomes much more

important as intermittent and

variable generation becomes more prevelant
