Solar Panel Battery Backup Storage
Remember Hurricane Sandy? Or the great ice storm of December 2013? Those storms deprived millions of households and businesses of electricity. Many did not get power back for days.
Extreme weather events like hurricanes, tornadoes and other storms are happening more frequently as our global climate shifts. It’s not uncommon for them to take down power lines. When they do, there’s no telling how long the power will be out.
Nearly everything you use in your home runs on electricity: Your lights. Your computer. Your refrigerator. Your air conditioning. Losing power may even mean losing the ability to cook your food, heat your home, or even access clean, safe drinking water. Could you survive 10 days without power?
Solar Power Battery Backup: Built-In Power Outage Protection
Many people assume that if you have solar panels, you’ll have power when the grid goes down. Unfortunately, with a grid-tied system, this is not usually the case. To operate your solar panels independently of the grid, you also need to have some kind of on-site solar energy storage. Typically, that means solar power battery storage.
Solar battery backup is an ideal solution if you are concerned about electrical grid failure. With an independent battery solar power bank, you can continue to enjoy electricity, even when everything around you goes dark.
How Solar Panel Battery Backup Works
Most solar power systems are designed to either connect to the grid or to be completely off grid — not both.
The reason for this lies in the inverter. This is a component that converts the direct (DC) electrical current that your solar panels produce into alternating current (AC) power — the type of electricity that powers the lights and devices in your home or business. While it is simple in concept to add a battery bank to a grid-tied solar system, in reality you can’t use a typical grid inverter with batteries.
In addition to a solar panel battery bank, our battery/grid solar systems include a special, dual-purpose inverter capable of sensing when the grid power goes off or comes on, and switching to the correct mode — the best of both worlds.
Who Should Consider Solar Power Storage?
Batteries do add somewhat to the cost of a system, so they are considered optional. However, if you experience frequent power outages, or if losing power is more than a minor inconvenience for you, we encourage you to consider solar battery backup. It is far more cost effective to install them in the first place than to have to redesign your entire system later.
Unlike a backup generator, this type of solar energy storage is noiseless, doesn’t require fuel, and switches on automatically when the grid goes down. Battery power starts smoothly, without the 10-15 second delay that is common when a generator starts.
Your solar power battery storage system will also recharge your batteries automatically — an important feature in the event of a long-term power outage.
One More Critical Thing …
When designing a grid-tied battery solar system, it’s even more important than usual to size it right. That’s because you want to be sure you’ll have enough power to cover your critical loads (most important uses of electricity) should the grid go down.
