Getting Started With Solar Panels in Washington County
Washington County homeowners can use solar panels to produce clean electricity at home.
Solar power in local areas like Hillsboro, Beaverton, and Tigard involves the installation of photovoltaic panels on rooftops or on the ground, harnessing sunlight to generate electricity.
This guide provides a comprehensive overview of residential solar power, including how the technology works, how Pacific Northwest weather might affect solar panels, and why it makes sense to install them in Washington County.
How Do Solar Panels Work?
Washington County solar panels collect sunlight with photovoltaic cells and send the power through an inverter to your home.
These solar cells have a special photovoltaic material, usually silicon, that absorbs photons from sunlight. The photons knock electrons loose from their atoms, allowing the electrons to flow freely and generate a current.
The solar cells are wired together in a panel to produce direct current (DC) electricity. This DC passes through an inverter, which converts it into alternating current (AC) electricity that can be used to power homes and appliances.
The basic steps in how solar panels generate electricity are:
- Photons from sunlight hit the solar panel and are absorbed by the solar cells.
- These photons contain energy that knocks electrons loose in the solar cell material, allowing them to flow freely.
- The free-flowing electrons generate direct current (DC).
- An inverter changes the DC to AC.
- The electricity is then ready for use in the home or to be fed back into the utility grid.
To summarize, solar panels produce clean renewable electricity by converting sunlight into an electric current using special materials like silicon. This conversion happens through the photovoltaic effect at the atomic level inside the solar cells. They require no fuel other than sunlight to generate emissions-free power.
What About The Weather?
Solar works in Washington County year-round, with its best output in summer.
Contrary to its reputation for rain, Washington County enjoys lengthy daylight hours in summer, which helps solar production. While many may initially believe rain is bad for energy production, rain helps clean off debris that may accumulate on the panels, increasing efficiency once the sun is back out and shining.
Furthermore, solar panels installed in Washington County, Oregon are designed to capture scattered light, effectively converting it to usable electricity even on overcast days.

Environmental Benefits of Solar Power
Going solar lets you reduce pollution and your carbon footprint at the same time.
Solar energy doesn't emit harmful greenhouse gases and aids in battling climate change. Crucial environmental benefits include:
- Reduction in carbon emissions: By utilizing solar power instead of fossil fuel-generated electricity from the grid, homeowners can significantly cut carbon emissions associated with their energy use. This directly decreases their carbon footprint. Solar panels produce no direct emissions while operating.
- Conservation of water resources: Fossil fuel energy production consumes vast amounts of water. Solar power cuts this demand, conserving freshwater resources. This is especially important in arid regions facing water scarcity.
- Decrease in dependence on fossil fuels: Widespread adoption of solar energy reduces reliance on polluting energy sources like coal and natural gas. This facilitates a cleaner energy mix for the future.
- Promotion of a healthier environment: By curbing air pollution and emissions, solar power contributes to better air quality and environmental health. This benefits public health as well.
The Installation Process
Washington County solar installers assess your property, design a system, handle permits, install, and test.
Property Assessment
Washington County solar installers will evaluate the property's suitability for solar panels, considering factors like structure, sun exposure, and energy usage patterns. This allows them to determine the ideal system design and placement.
System Design
A tailor-made solar panel system is designed specifically for the property to maximize efficiency and aesthetics. The experts take into account the roof layout, ideal tilt angles, solar access, and expected energy needs.
Securing Permits
The necessary permits, including building and electrical permits, are obtained on the homeowner's behalf. This simplifies the complex process of navigating local regulations and codes.
Installation
Once the permits are secured, experienced technicians will install the solar panels and other system components. This is when the property begins its transition to solar power.
Testing
Thorough testing and commissioning ensure the system functions as intended before completion. The technicians verify correct wiring, performance, safety, and integration with the home's electrical panel. If your panel is old or can't handle the added load, we'll let you know during system design and recommend an electrical panel upgrade.
Throughout this streamlined process, the homeowner can expect clear communication and steady support, making the switch to solar energy simple and straightforward.
Types of Residential Solar Installations
Washington County solar installs come in different layouts, so the system can match your property.
The main types of solar installations are:
Rooftop Solar
Rooftop solar panels are installed directly on the roof of a home or building. This is a popular option for many homeowners as it utilizes unused roof space to generate electricity.
- Make efficient use of space, not requiring additional land
- Can meet much or all of the home's electricity needs
- Close proximity to the point of use reduces energy loss
Ground-Mount Solar
Ground-mount solar arrays are installed on the ground, often in backyards or open spaces on a property.
- Allows flexible positioning for maximum sun exposure
- Easily scalable to increase system size

Net Metering: How Does It Work?
Washington County solar owners can use net metering to bank credit for surplus power and use it later.
Here's a quick rundown of how those credits work:
- Your solar panels may produce more electricity than you use during sunny daylight hours. This excess energy gets fed into the local utility grid.
- The utility company installs a special net meter at your home. This meter can spin backward when your solar panels generate extra electricity, unlike a standard meter which only goes forward.
- At night or during cloudy weather, when your solar system produces less power, you pull electricity back from the grid.
- At the end of each billing cycle, your utility company calculates the net difference between what you took from the grid versus what you supplied back.
- If you give more power than you use, your net meter reading will be negative or in "credit" - and the credits roll over on your electricity bill.
- Depending on your state's net metering policies, your utility company may also pay you for excess credit over a year.
So in short, net metering provides a direct financial incentive for going solar by giving you credit for the extra clean power you produce. Those credits can offset your electricity purchases from the grid when needed.
This means that for many solar homeowners, annual electricity costs drop. How much depends on your system and usage.
