To get the right combination of solar panels and battery storage, homeowners from Phoenix to Tucson rely on the pros at Energy Solution Providers. The amount of backup power you need will depend on the size of your home, the appliances you have, the amount of energy you consume, and many other factors. How Many Batteries Do You Need for Off-Grid Solar?Ĭalculating the amount of electricity your home needs is an important step in equipping an off-grid home, both for the number of solar panels and the number of storage batteries. In an off-grid system, all that excess electricity is stored in solar batteries, giving you a backup power source that you can use at night or when it's overcast. We get a lot of sunshine here in Arizona, and on most days, your solar panels will produce more electricity than you need. Excess Electricity Is Stored in Solar Batteries Throughout the day, the solar inverter converts DC electricity to AC electricity that is fed into your home’s electrical system. Appliances, heating and cooling, lighting, and essentials such as sump pumps, well water pumps, and septic systems are powered by AC electricity. Solar Inverters Convert DC Electricity to AC Electricityīecause the electricity produced by the solar panels is direct current it needs to be converted to alternating current (AC) for household use. The panels are either ground-mounted or roof-mounted and connected to a main DC power line that connects to the system’s inverter. Solar companies install PV panels to maximize the arc of the sun throughout the year, facing in a generally south direction, at an angle. Residential solar photovoltaic (PV) panels collect energy from the sun and convert it into direct current (DC) electricity. Here’s how an off-grid solar system works step-by-step: 1. Off-grid solar systems must include battery storage and many off-grid homes also include a backup generator for additional backup power. The difference is that off-grid systems are not connected to the electric grid and cannot access the electricity that it generates your off-grid system needs to be able to meet your electricity needs fully. ![]() Off-grid solar systems generate power the same way grid-tied solar systems do. ![]() Many homeowners wonder what the meaning of an off-grid solar system is. Keep reading to learn more about how off-grid systems work and how you can go off the grid with solar. Like solar panels, battery backups have improved in design and efficiency and come down in price in recent years, making off-grid solar a viable option for many Arizona home and business owners. Off-grid solar systems in Arizona rely on solar battery banks to store solar energy so that it can be used at any time of the day or night. Off-grid solar systems provide 100% of the power a home or business needs by transforming energy from the sun into free, renewable electricity.īut solar power is only available when the sun is shining, so how does an off-grid system work at night? That’s where battery storage comes in. Off-grid solar makes it possible to live a comfortable life or run a successful business without having to rely on a utility company for electricity.
