Once you go solar with Harmon, you’ll use less energy from the utility. New solar battery technology is dramatically expanding the effectiveness of typical solar energy systems by giving homeowners and business owners the flexibility to create and use power how they want and when they need it.
Whether it’s Tesla’s new PowerWall, a cordless drill power-pack or a golf cart battery, the concept is the same: a charged battery stores electrical energy for later use.
In the last ten or so years, there has been over $17 billion in private research and development focused on energy storage. Advancements are happening fast. And customers are benefiting significantly.
When it comes to batteries, price and capacity are the most important criteria. You must be able to store enough electricity to power your home or business (CAPACITY) at a price that is lower than what you can buy the same amount of power for from your local utility company.
"We are very pleased with the solar installation on our home.
The representatives listened to my concerns and went above and beyond to alleviate the same.
Work was performed professionally and timely."
Co-owner of Harmon Electric / Solar, Dan King, turns off his connection with the utility and relies solely on his 15.0 kw solar system and three Tesla Powerwalls for two days. Tesla states on their website, "PowerWall can detect an outage, disconnect from the grid, and automatically restore power to your home in a fraction of a second. You will not even notice that the power went out. Your lights and appliances will continue to run without interruption. If you have solar and PowerWall, then solar energy will continue to power your home and recharge PowerWall. Without PowerWall, solar will shut down during an outage." And it proved to be true.
Of the 3 most common battery types, Lithium-Ion Batteries are the most popular. Although a bit more costly than Lead-Acid and Flow Batteries, Lithium-Ion batteries that are connected to your local utility grid provide superior performance and have proven their reliability.
At Harmon, every residential and commercial solar system we design and install is “fully forward compatible” with storage, whether or not a solar battery pack is installed at the time of the initial installation. These solar batteries will keep your power on when the sun (or the utility grid) is down.
