Can Home Battery Storage Work For Me?

Sonnen home battery storage solution

Many customers are wondering if now is the time to add home battery storage to their Solar Tracker systems.  With an 80% drop in lithium ion battery prices in the last five years, more affordable options are now available to store solar output for times when you need it most.  Better still, battery storage qualifies for a 26% Federal Tax Credit when installed with a new or existing solar system.  Here are six reasons why adding a home battery may make sense for you:

  1. Solar when the power is out.  Most solar arrays are designed to shut off when the grid goes down to protect line workers as they fix the grid.  A home battery equipped with a smart inverter allows your Solar Tracker to keep home electrical devices running, without the need to fire up a generator.  Weather permitting, a solar-charged battery can cover a power outage up to several days.
  2.  Solar when you want it.  A Solar Tracker typically produces more power than you need during the day (and, of course, no power a night).  A home battery system stores the power for your preferred times of use, like when you’re at home and running more of your appliances and favorite electrical devices.
  3. Solar when it pays the most.  Your Solar Tracker takes any excess power not used in your home and sells it into the grid; otherwise the power is lost.  By adding a home battery, you can store some of this power for sale at times of peak demand, when spot prices are high.  Time-of-use-pricing – which is available out West and should be coming soon to the Northeast – constantly monitors this demand and can be used to dispatch power when it’s fetching the highest price.
  4. Solar that keeps your electric vehicle on the go.  A Solaflect Tracker produces enough electricity for 20,000 miles of driving a year for an average EV, at a price equivalent to about 75¢/gallon.  That’s a savings of about $2,000 a year if you drive 10,000 miles a year – all without tailpipe or carbon emissions!
  5. Solar to help utilities meet their goals.  You’re not the only one trying to shrink your carbon footprint.  Utilities also have goals to boost renewable energy use; priority is often given to in-state sources that promote local jobs and greater energy independence.  Batteries charged with solar power are key to building out “virtual grids” that offer cleaner, more reliable and affordable electricity for your home and the local power company.
  6. Solar that powers the 21st century grid.  The move to electric vehicles with eventual bidirectional charging is changing how we think about the grid.  In Vermont, we estimate that 25,000 EVs equipped with the latest batteries could meet a goal of 20% power from in-state renewables.  This would eliminate the need for large, utility-scale battery plants, and boost local jobs and local control over future energy management decisions.
