Key Components of Home Solar Power Systems in Oregon

Reputable solar companies in Oregon custom design home solar power systems. Every rooftop site is unique, and homeowners differ in terms of energy usage, so the configuration is individually planned to meet each customer’s needs.

That being said, most home solar arrays in Oregon share the same basic components. Here’s a look at the main parts of a residential rooftop PV system.

Solar Panels

Photovoltaic modules, or solar panels, are the core of any home solar power system. Comprised of dozens of PV cells, the modules soak up sunlight and transform it into electric energy – that’s what’s known as the photovoltaic effect. The greater the electricity usage of an Oregon household, the more PV modules are needed.

Solar Inverters

Direct current (DC) electricity is the type of energy created by the photovoltaic effect, but as you likely know, almost all homes in Oregon use alternating current (AC) electricity. Residential solar power inverters are designed to take in the DC energy produced by PV modules and convert it into useful AC electricity.

Mounting Racks

The rooftop is the most common site for home solar power systems, and professional photovoltaic contractors in Oregon use mounting components that are specifically designed for residential PV modules. The racks may require that a few holes be drilled in the roof, but special flashing and silicone work to create a leak-free, watertight seal.

Wiring and Connections

In a residential rooftop PV system, the solar panels are wired together in a series or string to form an array. Wires connect the string to the inverter and to a home grounding system. Wiring is also used to provide a connection with the utility grid, allowing for both net metering and a steady supply of electricity for use when the sun isn’t shining.

Utility Power Meters

Oregon homeowners benefit greatly from net metering, as the policy allows them to generate their own electricity and send any excess energy produced to the grid. Credits for that energy appear on their utility bills, significantly lowering or even completely offsetting the amount due. A special power meter is necessary to make this all possible.

Monitoring Systems

Residential solar power systems often have in-home monitors that track energy output. Many homeowners in Oregon go the extra mile by adding a web-based monitoring system, as this makes it easy to keep an eye on electricity production and household usage. And, alerts can be configured to notify homeowners of performance issues.
