How Grid-Connected Solar Systems Function
At its core, a grid-connected solar system is designed to harness the sun’s energy and convert it into usable electricity for your home, while simultaneously interacting with the existing electrical grid provided by your utility company. This interaction is the defining characteristic of these systems.
The Role of Solar Panels (Photovoltaic Modules)
Your solar system begins with solar panels, also known as photovoltaic (PV) modules.
Solar Cells and Sunlight Conversion
These panels are composed of numerous solar cells, typically made from silicon. When sunlight strikes these cells, it excites electrons, creating a direct current (DC) flow of electricity. The more direct sunlight that hits the panels, the more electricity they generate. The orientation and angle of your roof in Sendero Springs play a crucial role in maximizing this energy capture, with south-facing roofs generally being optimal in the Northern Hemisphere.
Panel Efficiency and Output
The efficiency of a solar panel refers to the percentage of sunlight it can convert into electricity. While laboratory efficiencies are constantly improving, commercially available panels for residential use typically range from 17% to 22% efficiency. The total output of your system will depend on the number of panels, their individual wattage, and the available sunlight, often measured in kilowatts (kW).
The Inverter: Bridging DC and AC Electricity
The electricity generated by your solar panels is in the form of direct current (DC). However, the appliances in your home and the electricity grid operate on alternating current (AC). This is where the inverter comes into play.
Types of Inverters
There are generally two types of inverters used in residential grid-connected systems: string inverters and microinverters.
String Inverters
A string inverter is a central unit that connects to multiple solar panels (forming a “string”). It converts the DC electricity from all panels in that string into AC electricity. This is a more traditional and often more cost-effective solution.
Microinverters
Microinverters are installed individually on each solar panel. They convert DC to AC electricity at the panel level. This offers advantages like maximizing energy production from each panel independently, even if some panels are shaded or experience different levels of sunlight. They also provide panel-level monitoring.
Managing Power Flow
The inverter’s primary function is to convert the DC energy from the panels into AC energy that you can use immediately in your home. It also manages the flow of electricity between your home, the solar panels, and the utility grid.
The Connection to the Utility Grid
The most critical component of a grid-connected system is its link to the existing electricity grid.
Net Metering and Exporting Excess Power
When your solar panels generate more electricity than your home is currently consuming, the excess power is exported back to the utility grid. In Texas, most utilities offer net metering or a similar compensation mechanism. Under net metering, the electricity you send back to the grid is credited to your electricity bill. This essentially means you’re trading your excess solar electricity for future electricity you might need from the grid.
Importing Power When Needed
Conversely, when your solar panels are not generating enough electricity to meet your home’s demand (e.g., at night or on heavily overcast days), you automatically draw electricity from the utility grid, just as you would with a traditional energy setup. You are billed for this imported electricity according to your utility provider’s rates.
The Role of the Utility Meter
Your existing utility meter is replaced with a bi-directional meter, also known as a net meter. This meter accurately tracks both the electricity you import from the grid and the electricity you export to the grid, forming the basis for your billing and credits.
