    Oregon Solar Panel Guide for Homeowners and Business Owners

    Since the Willamette Valley is notorious for cloudy and rainy weather, it may not seem obvious that Oregon is one of the best states for installing home solar panel systems.

    In this article, we’ll explore;

    1. how solar in Oregon works

    2. what benefits you can expect, and

    3. how many solar panels you might need

    Our team of solar experts here at Sunbridge Solar is here to help, so if you have any additional questions about Oregon solar panels that we didn’t answer in this article, please get in touch with us!

    Quick Look: Solar Panels Oregon

    You may have already typed in Google, “solar panels Oregon” and done a bit of research, about the different types of solar energy. For a quick refresher, it’s important to distinguish that there are two types of solar panels: photovoltaic (PV) panels that produce electricity and solar thermal panels that are used to generate heat. For the purposes of this article, we will solely be looking at photovoltaic solar panels. Most solar companies in Oregon – as well as here at Sunbridge Solar – install only PV panels and not thermal solar panels.

    Essentially, a solar panel collects photons (particles of light) from the sun, which then knock electrons free from atoms within the panel materials, which generates an electrical current. 

    Each solar panel is actually a frame that contains many individual solar cells. If you have multiple solar panels wired together, that constitutes a solar array, and when the array is connected to batteries, inverters, and your home’s wiring, it becomes a solar energy system.

    Grid-Tied Vs. Off-Grid Systems

    Grid-tied systems are installed on homes that are already connected to a local energy utility grid, for the purpose of reducing energy costs and providing backup power in the case of a grid outage. If your solar energy system creates more electricity than you use in a month, you can usually take advantage of net metering, which allows you to amass credits for the excess energy you produce, which can be applied to your energy bills in subsequent months when your energy production is lower or your consumption is higher. If your system does not produce as much energy as you use, you will simply be charged the difference for grid electricity.

    Off-grid systems are primarily used in very remote or rural settings where no utility connection exists. They are designed to charge a battery system, which then provides power at night or whenever the solar panels are not generating power.

    Are Solar Panels in Oregon Efficient?

    Solar panels are very efficient, especially in Oregon. There are several factors that affect the efficiency of solar panels, but we’ll explore the four biggest factors.


    The first and most obvious factor is the amount of sunlight that hits the solar panel. Of course, this will vary during different seasons, since the days are significantly longer and generally sunnier in the summertime in Oregon when compared to winter days. However, solar panels do not need direct sunlight to produce energy, so even on cloudy or overcast days, they will still generate some electricity.


    Next up is the average temperature of the area. Solar panels lose efficiency the hotter it is, and actually have a temperature coefficient rating, which essentially indicates the percentage of power generation loss for each degree Celsius above 25 degrees Celsius (77 degrees Fahrenheit). Fortunately, Oregon is not exceptionally hot, so solar panels tend to do well and generate power efficiently here.

    Types of Solar Panel in Oregon

    The type of solar panel you select also dictates the overall efficiency of your system. Each model of solar panel has an efficiency percentage rating that’s generally between 15-20%, although some newer panels have ratings as high as 22%. The current drive in the solar panel industry is to improve the efficiency of panels while still keeping the costs reasonable.

    Angle and Orientation

    Finally, the angle at which your solar panels are mounted has a significant impact on efficiency. Solar panels work best when the sun is hitting them straight-on. Obviously, the optimal angle to achieve this varies throughout the year, but here in the northern hemisphere, the sun will always be to the south, so mounting solar panels on a pitched south-facing roof surface is the most effective.

    If you want to maximize your energy production, you can design your mounting system to be adjustable so that you can change the panel angle throughout the year.

    How Many Solar Panels Do You Need?

    This depends entirely on your household. A good way to decide what size of the system is appropriate for your home is to determine your current electricity consumption, assessed at different times of year – people generally have the lights on more in the winter and use energy to heat their homes, and don’t use as much energy in the summer unless they are running air conditioning units.

    You can find your consumption amount in kWh on your current energy bill to help find out how many solar panels you will need to power a house.

    100% Offset Using Just 13 To 33 Solar Panels

    Then decide how much of that energy consumption you can feasibly cover by analyzing your roof’s capacity for holding solar panels and the number of sunshine hours the panels will receive.

    In general, each kW of solar panels will require 100 square feet of south-facing roof space. Residential solar energy systems commonly range from about 4 kW to 10 kW to generate 100% of the home’s energy consumption or 13 to 33 solar panels to offset your consumption by 100%

    Are Solar Panels Worth It in Oregon?

    Installing a solar energy system at your home is definitely worth it.

    A Few Advantages

    Solar power provides a clean, renewable, emission-free energy source, which is critical in today’s environmental crisis. Installing solar panels will significantly reduce your carbon footprint, something we all need to strive to protect the planet.

    Nowadays, solar installations in Oregon are increasingly affordable, especially with federal, state, and local incentives. Most solar energy systems have a lifespan of about 25 years, and many systems will pay themselves off within 10-12 years, so you will get to enjoy free or very low-cost clean energy for over a decade.

    Solar energy also increases your home equity by an average of $14,000, so even if your plans change and you end up moving out of your home before the solar energy system has reached the end of its lifespan, you can get most or all of your initial investment back.

    You can also set up your solar energy system to provide backup power in the case of a grid outage, which will keep you comfortable and prevent the food in your refrigerator from spoiling every time the power goes out.

    A Few Disadvantages

    There are very few disadvantages of solar panels. One may be that the initial investment costs are significant, but even this large expense can be cut by up to 50% by taking advantage of all the federal, state, and local solar incentives.

    It could also be argued that solar panels are unsightly, but manufacturers are making increasingly sleek and unobtrusive panels that blend right into your roof. Tesla is also working on photovoltaic roof tiles that would be indistinguishable from regular solar roof tiles.

    Is It Worth Getting Cheap Or Free Solar Panels?

    In general, no. If you are going to spend the money to invest in a solar energy system, you will be much better off long-term if you invest in high-quality panels and other solar components. However, as we’ve mentioned, high-quality equipment doesn’t necessarily have to break the bank. Plus, it is now easier than ever to obtain financing for your solar project, so you can spread out the cost over several years.

    Cheap solar panels are likely to be less efficient, less durable, and have a shorter lifespan than better quality panels, so you may end up spending more money on maintenance and repairs than you would have on one set of high-quality panels that do not require much maintenance.
