Grid - Tied System - Grid-tied solar electric systems generate electricity for your home or business and route the excess power into the electric utility grid for compensation from the utility company. www.wholesalesolar.com/grid-tie-packages ; for more details see Grid - Tied System

Grid-Tied Solar Power Systems with Battery Back-up - When the grid is running properly, your home or business will use power generated from your solar panels or pull electricity from the grid. Any excess power generated over and above your needs go back to your utility company for credits on your power bill in areas where net-metering is available. In the event of grid blackouts, these systems will switch to "off-grid mode" drawing power stored in your battery bank to power your home AND using your solar panels to recharge your battery bank. These systems come with battery banks, but unlike a normal grid-tied system, a grid-assisted system can draw extra power FROM the grid (to help power your appliances or charge your batteries), but it cannot feed power back INTO the grid. www.wholesalesolar.com/grid-tie-battery-backup ; for more details see Grid - Tied With Battery
Off-grid Solar Power Systems - The systems are all "stand alone" systems, capable of producing electricity from solar energy and storing it for use when the sun is not shining. www.wholesalesolar.com/off-grid-packages ; for more details see Off - Grid System
