Don't Lose Power During an outage and cut your energy bill completely
Going off-grid may seem scary at first
Going off-grid with your solar installation can seem scary. You may be asking “What if it’s too dark for too long?” or “What if I don’t produce enough energy?”. North Texas Solar can answer all these “What if’s” by their expert quoting and installation services. If your plan is to go off-grid there are three crucial things you should know:
#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.
