How Solar Works

Solar Modules

Photovoltaic (PV) modules are mounted on the roof or the grounds of your facility. The module is made up of PV Cells which convert sunlight into electricity in the form of a direct current (DC). When sunlight strikes the PV cell it excites electrons which run through extremely thin wires along the top layer of the PV cell which is encapsulated by a glass or plastic cover to protect it. The Photovoltaic modules are connected together to form an array. The array is connected to an inverter.

Inverter

The inverter takes the Direct Current (DC) of the PV module and converts it to Alternating Current (AC) which is the identical power sent to you by the utility grid.

Electrical Panel

Power travels from the inverter to the facility’s breaker box / electrical service panel. Once this is completed the electricity is available for your facility’s needs.

Utility Grid

In order to provide electrical power during the time the PV system isn’t producing enough electricity, or for those times when excess electricity is produced, the system needs to be connected or “tied-in” with the utility grid. (Customers wishing to be completely independent of the electrical power grid or planning to use the grid solely as a backup may want to discuss the use of batteries and fuel cell systems. Also, to combat spikes and the penalties associated with high peak pricing, Ultra Capacitors may be considered and incorporated into the customer’s custom design.)

Net Metering

A net metering agreement states that the utility will allow the generator of solar electricity to receive full compensation for any unused electricity that is provided to the utility electric grid at the wholesale rate. Renewable energy generators may see a credit applied to their traditional electric bill for renewable energy provided to the utility.

A Time-Of-Use Meter

A time-of-use meter allows credit for power sent at higher peak rate (most expensive rates) periods and debits during off peak rate periods (less expensive rates). Peak rates are determined by the time of day, day of the week and month of the year. This system is only effective if you generate more power than you use. Bottom line, if consumption is greater that the output to the utility grid, then a “spin Backwards” effect is not possible.
