For years, you really only had one option to power your home: connection to the electrical grid, which subjected you to usage rates that could fluctuate seemingly at the whims of your utility company. Today, you’re no longer stuck in this arrangement—it’s easier than ever to power your home on your own using clean, sustainable solar power and a battery-backup system.
How it Works
Solar power is great for producing electricity, but only during the day when most homeowners are away at work. At these times, municipal grids usually face an abundance of excess electricity because generation far exceeds consumption. Later on, when homeowners return home from work, energy usage spikes, placing a lot of added stress on the power grid.
The same is true for your solar panels.During the day, high-efficiency solar panels will generate clean, renewable power. However, without anywhere to go, that power will simply disappear uselessly. A battery backup system instead takes this excess energy and stores it in a battery system for future use. When your panels can no longer generate enough power to sustain your home, your batteries switch on, providing you with clean, reliable power.
Those Batteries Store a Lot of Power
As you can imagine, battery powering your home requires more than just your average AA-cell alkaline batteries like you put in the TV remote. At RevoluSun, we’re proud to be a certified installer of the Tesla Powerwall, the latest and greatest in home battery backup technology. These systems use high-capacity lithium-ion type batteries to store an immense amount of excess energy that your solar panel system generates but your home doesn’t use, allowing you to keep it for later when the sun goes down. When there is enough sun, solar power and a Tesla Powerwall system can keep your home powered and running indefinitely.
The Tesla Powerwall installs easily in nearly every type of home, and many states, including Hawaii, are considering incentives and tax credits to homeowners who install these systems and reduce the strain on our state’s aging electrical infrastructure.
And perhaps the best benefit is this technology is the cost, which has dropped tremendously over the last few years. In fact, the cost has dropped an average of 24% per year since 2010. Whereas these systems cost upwards of $800 per kilowatt hour as little as five years ago, today the average cost is hovering somewhere around $250 per kilowatt hour, dramatically reducing the payback period.
