There are three basic types of Solar Electric Systems The "grid-tie", "grid-tie with battery back-up" and "stand-alone" systems. Ranch Hand Solar Project installs all three types our systems, depending on their specific needs.

GRID-TIED SOLAR ELECTRIC SYSTEMS

Grid-Tied solar electric systems are the most efficient type of system and the least costly, making them the most common. The system consists of photovoltaic solar modules and an inverter. The modules, which can be mounted either to an existing roof or on a ground-mounted structure, convert the sun’s energy into direct current (DC) power. The Inverter takes the DC power from the modules and converts it to high quality alternating current (AC) electricity, which is compatible with your home and the utility. The inverter is then tied into your electrical breaker panel allowing you to use the sun’s energy to power your home or business. Grid-tied systems must be connected to the utility to function; therefore they do not operate during a utility power outage.

GRID-TIED with Battery Back-Up SOLAR ELECTRIC SYSTEMS

Grid-Tied with Battery Back-Up solar electric systems differ from straight grid-tie systems in that they have a battery bank and will continue to operate when there is a power outage. They operate in conjunction with the grid just like a grid-tied solar electric system, but if the power goes out your solar electric system will continue to power critical circuits in your home. Battery Back-up solar electric systems have a higher cost of installation, and the system is not as efficient as a straight grid-tied system.

STAND ALONE SOLAR ELECTRIC SYSTEMS

Stand-Alone solar electric systems operate on the same basic principles as grid-tied with battery back-up systems, however instead of tying into the local utility they function independently from the grid. They are used for properties where utility power is not available, or very costly. A stand-alone system utilizes a battery bank to store the energy produced by the modules, allowing you to draw electricity even when the modules are not receiving energy from the sun. After being stored in the batteries, the DC power flows to the inverter where it is converted to AC electricity for use in your home.
