How the solar system integrates with the Grid (Net Metering)

In a Net Metering installation, the solar panels supply electricity to the customer during daylight hours with any additional required power supplied from the utility. Surplus solar-derived electricity is sold back to the grid at either a pre-determined price or as a retail credit, depending on local regulations.  This allows the system to generate electricity during peak sunlight hours and reduce overall energy costs. This type of setup also allows the option of battery storage for additional off-grid power or as back-up.  The diagram illustrates the basic setup. 

Ground Mount

Panels are mounted on racks on open ground.  Physical ground is required but there are no constraints regarding the age of the roof.

Building Integrated

Panels are integrated onto the building itself.  

Basic Types of Solar Systems

A solar cell is a photo-diode which is made from semi-conductor grade silicon. When exposed to sunlight, electricity (DC current) is generated. Solar cells are joined together in a matrix to form panels. Panels are tied together to form an array that meets required power output. 

How Solar PhotoVoltaic (PV) Panels Work


Panels are mounted on the roof itself.  This requires a roof that will last the life of the PV system.
