Off-Grid Solar and Battery Back-Up keeps you up and running, even when the grid isn’t
making and Storing your own power gives you peace of mind
Battery Back-Up and Off-Grid Solar are the ultimate in energy independence. If the grid goes down energy storage keeps all of your most important things running. Keep you food from going bad, stay connected with a TV or wireless router, don’t lose critical medical equipment, and keep your security system up and running. Let us help you design a system to achieve all of your goals.
#1 - You need an energy storage system: The typical solar installation includes panels, inverters, racking equipment and a performance-monitoring system. However, for going off-grid, a battery bank needs to be added to the list to store the electricity for later use. Batteries can serve as a short-term backup when there is an outage, or even when the sun isn’t shining. In 2017, it was estimated that 43% of solar system installations were off-grid systems. According to a study by Grattan Institute, an average home needs a 7 kW solar system and a 35 kWh battery storage pack in order to achieve 95% reliability on solar power supply. Residential-scale solar batteries on the market today can store enough energy collected during the day for night use.
#2 - You need some space to store an energy storage sytem: A complete, off-grid system requires a bit of space. Although, it could also depend on the level of off-grid living you want to achieve. The average U.S. household uses about 11,000 kWh of electricity per year. Assuming that all solar panels are facing the appropriate direction, every square foot of roof space can generate 15 watts of solar energy. This means that a typical homeowner may need to install 25 solar panels. Since the most common solar panel size is 5.41x3.25ft, it would take almost 400 square feet of roof space to provide the right amount of electricity.
It’s not just the panels you need space for, you will also need space to house the solar batteries. For a functional off-grid system, approximately 20 to 30 solar batteries are required. The battery bank needs to be kept in a cool, dry area in order to increase its lifespan. With an efficient solar energy storage system, you will get the power you need, even with a couple of days of no sun.
#3 - With or without space, solar energy can still save you money: Going off-grid with solar is highly feasible but rarely cost-effective. Off-grid systems recommended for remote rural areas - such as farms - where bringing utility power can be expensive, making an off-grid system cheaper. There are also special cases wherein off-grid solar battery systems are the only option. GTM Research estimates that solar batteries will become a $2.5 billion market in the United States by 2020. By installing more storage technologies for renewable sources, the electricity generated can be more easily managed.
