Net metering is a service to an electric consumer under which electric energy generated by that electric consumer from an eligible on-site generating facility and delivered to the local distribution facilities may be used to offset electric energy provided by the electric utility to the electric consumer during the applicable billing period. continue..

When your home is equipped with a renewable energy source (such as wind or solar power), it sends the excess energy that's generated back into the grid to power other homes. An electrical converter called an inverter turns the DC (direct current) power coming from your renewable energy source into AC (alternating current) power, which matches the voltage of the electricity flowing through the power line. continue..

Net metering allows customers of certain electric distribution companies (note:  check whether your company is listed below) to generate their own electricity in order to offset their electricity usage.  All customer classes are eligible for net metering.  Common examples of net metering installations include solar panels on a home or a wind turbine at a school.  These installations are connected to a meter, which will measure the net quantity of electricity that the customer uses (“retail meter”).  continue..

The layout of the array was made to maximize the roof space given by the building, which was specifically designed to easily install the largest possible grid-tied system for the given area. The entire array will be placed on a South Facing roof at a 15ยบ inclination on a rib-type metal sheet, allowing for a quick installation and an optimal yield. An inverter room was provisioned on the top floor to house the 4 single phase inverters designed to connect to the building’s 3 phase Delta grid (230V Line-Line), which is a common grid constellation found in Manila.  continue..
