The term off-grid-solar power system refers to not being connected to a municipal electricity grid, mainly used in terms of not being connected to the main or national electrical grid. In electricity, off-grid can be stand-alone systems (SHS) or mini-grids typically to provide a smaller community with electricity. Off-grid electrification is an approach to access electricity used in countries and areas with little access to electricity, due to scattered or distant population. It can be any kind of electricity generation. The term off-the-grid (OTG) can refer to living in a self-sufficient manner without reliance on one or more public utilities.
If however you live in climate zone 1,2 or 3 off grid solar power systems may not be cost effective. They are best suited for mild climates that do not require air conditioning. But grid connected solar powered systems are PERFECT for extreme heat or cold! The power company buys or credits your energy production! Talk to an expert about solar panels for homes.
Before you think about Off Grid Solar Power Systems.. You must understand ELECTRIC POWER (inductance, Reactive,Resistive), induction motors, life style choices and complex systems that require maintenance and replacement. Unlike utility grid AC Power, 48 Volts Direct Current (DC) can stop your heart without the need of a ground path… DC power can also arc across the air! Children, animals, guest and other family members should not have access to this equipment. Also batteries must be in fire rated enclosures stored in temperature controlled rooms with fire protection systems (smoke, chemical and sprinkler system) for reliable power and long life. If not, what could have lasted 10 years, may only last 2-4 years ($$$$) and you may be setting in the dark during the winter months. Batteries for your car only require enough power to start an gasoline engine, batteries for a home requires more power than you ever thought.
Today’s new battery technology is being used in areas with high peak (middle of the day) energy charges like California. If you are a residential consumer of Texas grid power, off-grid has no economic value. However grid connected solar power systems can pay for themselves in less than 3-8 years! Talk to an expert!
Despite the hype or the desire to disconnect from grid power in Texas….THERE ARE NO U.L.Off Grid Solar Power Systems CERTIFIED for Residential use. Please let us know if a manufacturer, distributor or installer tells you anything different. Off Grid Solar Power Systems work best in climates that do not require air conditioning, DO NOT put these Off Grid Solar Power System in your garage or home. FIRE HAZARD! If your in Texas… Talk to an expert about grid connected systems and utility grade solar panels for home or business use.
