Solar 101

Solar panels or solar modules (which are normally installed on the roof) are made up of photovoltaic (PV) cells, and those cells convert sunlight into direct current power; keep reading for additional Solar Information Las Vegas.

The direct current (DC) power from those solar panels is sent to an inverter. From there it is converted into alternating current (AC) power, or standard electrical current that can be used in your home.The AC power then travels from the inverter to the electrical panel, which is often called a breaker box, and from there the power is ready to use in your home. In order to measure your electrical supply, a utility meter is set up to correctly monitor this. If your solar power system is producing more than necessary, the meter will spin backward, which will allow you to accumulate credit with your utility company towards your next bill. Also, your home will remain connected to the utility grid in order to supply you with extra electricity when you need it, most commonly at night. Should there be a power outage, National Electrical Code requires the solar system to shut down to avoid injury to crews.


With net metering regulation changes happening at many utilities nationwide, Energy Storage Technology is forging ahead in the industry. Storage addresses a fundamental problem of solar energy: while solar production peaks during midday, the rate of energy consumption can be at its highest in the morning and evening. With storage, you can save the energy you produce for when you need it most. Robco Electric will be beta testing the new Enphase Storage System on one of our homes later in 2016!

Here is a Storage Glossary of Terms:

  • Demand Charges are charges that commercial customers pay for the peak amount of power (load) that they draw from the grid. Demand charges can be a substantial portion of a utility bill; a battery helps lower them by allowing the commercial building to draw from the battery instead of the grid during peak times.
  • Demand Response programs compensate utility customers for reducing their electricity use (load) at the request of the utility.
  • Frequency Regulation happens when the utility calls upon batteries to inject power into the grid or take power off the grid to help the grid maintain a stable frequency. Battery owners are compensated for this service.
  • Lithium Ion is the overarching term for any lithium-based rechargeable battery. The name refers to lithium ions that are shuttled between cathode and anode when the battery is charged and discharged.
  • Load Shifting is the process of shifting the time when energy is used. For example, running the dishwasher at night to take advantage of off-peak energy prices.
  • Peak Shaving is the process of reducing peak power usage.
