When installing a new solar energy system – a lot of people ask, “Do I also need batteries in addition to my solar array?”
The answer is: “Maybe.” While the cost of batteries is still relatively expensive, prices continue to drop, and the peace of mind they can offer is often priceless. If you are prone to power outages, experience frequent inclement weather or are affected by major storms, then batteries may be right for you.
When you use a battery as part of your overall solar PV system, you can store the excess electricity your panels produce and store it for later use. The higher the capacity of the battery, the more solar power you can store.
Batteries work by using some of the power produced by your solar panels to charge your battery. The DC electricity produced by the solar panels is converted to AC power by a standard solar inverter or microinverters. This inverter supplies the solar electricity to your home. Excess electricity is routed to the battery, converted back to DC, and saved for future use. Just like a solar inverter is needed to convert the DC power to AC power, stored power in the battery is converted to AC power before it is used to power your home. Note: some batteries contain inverters integrated within the system. When a battery is installed – you may still send electricity back to the grid (in grid-tied systems). This only occurs when your battery is fully charged and your home does not consume all of the electricity produced by the solar panels.
At Hilton Head Solar, we design battery systems to provide power to the essential items in your home that need to operate in the case of a power outage. To remain cost-effective, we like to design our battery systems to handle emergency dedicated circuits first. Dedicated circuits such as your refrigerator, security system, internet router, a few kitchen receptacles, hallway and outdoor lights, and your water pump. While we would all like the batteries to be able to offset your cooling and heating loads – the power demands of most common cooling and heating systems cannot be supported by a standard battery system.
Whether you’re preparing for intermittent power outages, storm recovery or overall electricity system failure, our battery solutions can power your critical needs.
When we compare the cost of electricity purchased from the power company to the cost of electricity from solar, we find that the cost of electricity from solar is consistently less than the local power company. The cost of electricity from solar doesn’t go up every year like your power company bills do.
