Introduction to Oregon Solar Panels
Looking to reduce your energy bills, gain energy independence, and contribute positively to the environment? Consider installing Oregon solar panels in your home or business! With abundant sunlight (during the summer months) coupled with local and federal solar incentives, Oregon is an excellent location to utilize the power of solar energy.
This post is a comprehensive guide to everything about solar panels in Oregon. Let’s begin!
Solar Energy: The Basics
Solar panels, often referred to as photovoltaic (PV) panels, are the primary tool in harnessing the sun’s plentiful energy. This amazing technology allows us to tap into the most abundant energy source on earth, the sun, and convert it into usable electricity for our homes and businesses.
Each solar panel is made up of many photovoltaic cells, which are organized in a grid-like pattern on the surface of the panel. These cells are the heart of the solar panel as they perform the crucial task of energy conversion. They’re typically made from semiconductive materials like silicon, which generate an electric charge when exposed to sunlight.
The process is a bit like this: when sunlight, composed of tiny energy particles called photons, reaches the surface of a solar cell, it stimulates the cell and knocks electrons loose. This movement of electrons creates a direct current (DC).
|Key Components in Solar Energy Generation||Function|
|Photovoltaic Cells||Convert sunlight into DC electricity.|
|Inverter||Converts DC into AC electricity.|
|Electrical Panel||Distributes the electricity throughout the home or business.|
However, most home appliances and systems use alternating current (AC) not DC. That’s where the inverter comes in. An inverter is a vital piece of solar equipment that converts this DC into the AC, which is then fed into your home’s electrical panel and distributed for use.
Solar energy is clean, renewable, and abundant. It offers us an opportunity to lower our utility costs, reduce our carbon footprint, and contribute towards a more sustainable future. It’s an incredible process, and what’s even more remarkable is that all of this happens silently and without any moving parts!
Let’s look at the distinct solar characteristics of Eastern and Western (Willamette Valley) Oregon.
Eastern Oregon versus Western Oregon
Eastern Oregon and Western Oregon, particularly the Willamette Valley, present different solar opportunities due to their varied climates and geographic attributes. Let’s explore their differences with a comparative table:
|Eastern Oregon||Western Oregon (Willamette Valley)|
|Climate||Semi-arid and experiences more sunny days annually.||Temperate maritime climate with more cloudy and rainy days.|
|Average Annual Sunlight Hours||Approximately 3000 hours.||Approximately 2000-2500 hours.|
|Solar Power Potential||Higher due to increased sunlight.||Lower due to cloudier and rainier conditions, but still substantial.|
|Solar System Efficiency||Likely to be higher because of more consistent sunlight.||Might be slightly lower due to fewer sunlight hours but modern panels are designed to function well even in less sunny conditions.|
|Solar Installation Cost||Can be similar as the costs are more affected by system size, technology, and installation specifics rather than location.||Same as Eastern Oregon.|
|Solar Incentives and Policies||The same statewide and federal incentives apply. Check with local solar electric providers for city-specific incentives.||The same statewide and federal incentives apply. Check with local solar electric providers for city-specific incentives. Now, let’s delve deeper into some key factors:|
Climate and Solar Potential
Eastern Oregon has a semi-arid climate and enjoys more sunny days throughout the year compared to Western Oregon. This greater amount of sunlight naturally results in higher solar power potential, meaning solar panels in Eastern Oregon might produce more electricity on average than those in the Willamette Valley.
However, Western Oregon, particularly the Willamette Valley, while having a temperate maritime climate with more cloudy and rainy days, still has significant solar potential. Modern solar panels are designed to function well even in less sunny conditions, capturing diffuse light on cloudy days. Therefore, despite receiving fewer annual sunlight hours, the region can still benefit substantially from solar energy. One benefit of more rain is less dust and debris may accumulate compared to less rain and dustier Eastern Oregon.
Solar Installation Costs and Incentives:
The costs of solar installations in both regions can be quite similar as they are more influenced by the size of the system, the type of technology used, and specific installation aspects rather than geographic location. Both regions also have access to the same statewide incentives, such as the Oregon Department of Energy’s Solar + Storage Rebate Program, the Energy Trust of Oregon’s Solar Within Reach program, and the Federal Solar Tax Credit. However, regional solar incentives may vary.
In short, while Eastern and Western Oregon present different climates and solar potentials, both regions offer significant opportunities for harnessing solar energy. The critical factor is choosing the right system for your specific location, needs, and budget.
Tesla Solar Shingles VS Traditional Solar Panels
Let’s take a detailed look at the differences between traditional solar panels and Tesla Solar Shingles, two popular solar solutions available today.
Traditional solar panels, which you’re likely quite familiar with, are large, flat structures that are mounted on the roof of a building or on the ground. These panels are filled with photovoltaic cells that collect sunlight and convert it into electricity.
On the other hand, Tesla Solar Shingles, also known as Tesla Solar Roof, is a relatively new innovation introduced by Elon Musk’s company, Tesla Inc. These solar shingles are a combination of solar cells with traditional roofing materials, which means they serve a dual function: they protect the house from the weather just like ordinary roofing tiles, and they generate electricity from the sun.
Now let’s break down some pros and cons:
|Factor||Traditional Solar Panels||Tesla Solar Shingles|
|Appearance||While some people don’t mind the look of traditional panels, others may find them aesthetically unappealing. They are usually blue or black and can stand out, especially on older homes.||Tesla Solar Shingles mimic the look of traditional roofing materials and can blend seamlessly with the architecture of the house. They’re designed to be a part of the roof rather than something added on top.|
|Cost||Traditional panels are generally less expensive to install compared to Tesla Solar Shingles.||Tesla Solar Shingles can be more costly due to the integrated roof-and-solar technology and the installation process, which requires a complete roof replacement.|
|Efficiency||Solar panels tend to be more efficient at electricity production as they can be angled optimally towards the sun.||While improving, solar shingles may not be as efficient as traditional solar panels due to their flat position on the roof.|
|Installation||Panels can be installed on nearly any roof and adjusted for optimal sun exposure. It’s a simpler and quicker process than installing solar shingles.||Tesla Solar Shingles require a complete roof replacement and are more labor-intensive and time-consuming to install.|
|Durability||Solar panels are durable, but they’re also bulky and can be damaged by severe weather.||Tesla claims its Solar Shingles are three times as strong as standard roofing tiles and more resistant to weather damage.|
Despite the differences, both traditional solar panels and Tesla Solar Shingles offer the fantastic benefit of renewable energy, reducing carbon footprint and offering significant energy savings over time. The choice between the two will largely depend on individual circumstances like roof condition, aesthetic preferences, budget, and overall home design. It really depends on your budget and wants.
In sunny Oregon, either option can be a great choice, but it’s essential to consider these factors and perhaps consult with a solar professional before making a decision. Regardless of the choice you make, you’ll be contributing to a greener future with the power of the sun!
What is Total Solar Resource Fraction (TSRF)
In simple terms, the TSRF, or Total Solar Resource Fraction, is a measure used to assess the efficiency and effectiveness of a location for solar energy production. It gauges the total amount of sunlight that can be captured by a solar panel system installed in a specific site, taking into account factors such as geographic location, panel orientation, shading, and tilt angle.
|Key Factors in TSRF||Description|
|Geographic Location||Certain locations receive more sunlight due to their proximity to the equator.|
|Panel Orientation||Solar panels are most efficient when facing south in the northern hemisphere.|
|Shading||Trees, buildings, or other obstacles can block sunlight.|
|Tilt Angle||The angle at which the panels are installed affects the amount of sunlight captured.|
Why TSRF is Important
Why does this matter for Oregon solar incentives, you ask? The Energy Trust of Oregon, as part of its commitment to supporting sustainable, renewable energy, encourages the efficient installation of solar panel systems. To qualify for its solar incentives, your site must score at least 75% on the TSRF rating. This requirement ensures that the solar energy systems being installed are efficient and effective, and contribute meaningfully to the state’s renewable energy goals.
|Incentive||TSRF Score Requirement|
|Energy Trust of Oregon Incentive (PGE & PP)||75% or above|
Therefore, understanding and optimizing your site’s TSRF score isn’t just a technical detail—it’s a crucial step toward accessing the valuable solar incentives provided by the Energy Trust of Oregon. By doing so, you’re not only optimizing your own solar energy production and potential savings but also contributing towards a greener and more sustainable Oregon.
Solar Equipment Types
There are three main types of solar panels used in Oregon:
These panels are created from a single-crystal structure, which means they’re formed from cells made from a single crystal of silicon. The use of high-grade silicon contributes to their characteristic high-efficiency rates and their sleek, uniform black color.
- Highest efficiency rates
- Long lifespan
- Requires less space
- More expensive than other types
- Performance can decrease if covered by dirt or snow due to the entire circuit breaking if a section is covered
These are made from cells derived from various silicon fragments melted together. They have a blueish hue and a somewhat shattered glass appearance due to multiple crystals in each cell.
- Less expensive than monocrystalline panels
- Slightly less efficiency isn’t typically an issue unless space is limited
- Lower efficiency
- Requires more space for equivalent energy output
- Shorter lifespan
These are the least expensive and easiest to produce, made by placing one or more films of photovoltaic material (like silicon, cadmium, or copper) onto a substrate. They offer the least efficiency among the three types but are incredibly flexible in terms of design.
- Most affordable option
- Highly flexible, can be made into ultra-light and flexible formats
- Performs better in hot weather
- Lowest efficiency
- Requires a lot of space
- Not suitable for residential rooftops due to size and weight
- Shortest lifespan
Thin-film panels are often used in large-scale commercial projects or where space is not an issue due to their lower efficiency and larger size requirements.
Battery Backup and EV Chargers
A critical factor to think about when investing in Oregon solar panels is battery backup. A battery storage system captures and stores surplus energy produced by your solar panels. That stored energy can then be utilized during periods of low sunlight or during power outages. In this way, you’ve ensured a consistent, reliable supply of electricity regardless of the weather or time of day.
Moreover, here are some added benefits of having a battery backup:
- Reduces reliance on the grid
- Provides power during grid outages
- Enables you to utilize more of your solar power by storing excess generation for later use
Electric vehicle (EV) owners have another reason to smile. Solar panels can be used to power EV chargers. This means you can harness the sun’s energy to power not just your home, but also your vehicle, making your transportation greener and more sustainable.
Solar Panel Maintenance: Cleaning and Upgrading
Maintaining your solar panels involves regular cleaning and potential upgrades. Dust, bird droppings, leaves, and other debris can accumulate on the surface of your panels, impeding their efficiency. Hence, periodic cleaning is essential to ensure your system’s optimal performance. It’s recommended to have professional cleaning at least once a year, but you may need it more frequently depending on your location and environment.
In addition to regular cleaning, here are a few tips to maintain your solar panels:
- Monitor your system’s energy production regularly
- Inspect the panels for any physical damage
- Schedule annual professional inspections
When it comes to upgrading, it’s essential to consider your home’s electrical load. With the addition of solar panels, and possibly an EV charger, the demand on your home’s electrical system may increase, which could necessitate an upgrade to your existing electrical panel. It’s recommended to consult with a professional electrician or solar installer to determine if an upgrade is necessary and ensure it’s done safely.
Pros and Cons of Oregon Solar Panels
While not an exhaustive list, here are the major pros and cons of switching to solar in Oregon.
|Lower energy bills||Initial installation cost|
|Energy independence||Dependence on weather|
|Environmental benefits||Maintenance needs|

Energy Oregon Solar Incentives
The Energy Trust of Oregon offers cash rebates to homeowners and businesses who are customers of Portland General Electric or Pacific Power. These solar incentives can vary and are subject to availability. They are calculated on a per-watt basis.
To qualify for these solar incentives, you must reside or own a business within the service area of Portland General Electric or Pacific Power. Your property should fall under one of the following categories:
- Nonprofit or school-related
For eligibility, the solar installation should be new, meet all applicable standards, and have warranties on all parts. Moreover, it should comply with site-specific criteria such as total solar resource fractions and be connected to the grid.
The rebate incentives offered by utilities are as follows:
- Portland General Electric: $500 flat per project
- Pacific Power: $600 flat per project
Other OR Solar Rebates & Incentives
Like the sunlight, Oregon offers an abundant amount of various solar rebates and tax credits to incentive the installation of solar. Please check with your local solar installers as city-specific incentives are not all covered here.
Portland Clean Energy Fund
The Portland Clean Energy Fund was established as a community-led initiative to combat climate change’s disproportionate effects on communities of color and low-income residents. The fund can also be used to provide grants to nonprofits for solar energy system installations.
Solar Within Reach Program
Alright, let’s delve into an exciting solar initiative in Oregon known as the ‘Sunlight Within Reach’ Program. Spearheaded by the Energy Trust, this program is particularly geared toward making solar panel installations affordable for low-income families. The upshot? A considerable reduction in their energy expenses.
In terms of eligibility for this Oregon-based solar perk in 2023, you must be the proud owner of a dwelling in any of the following categories: a solo-family house, multiple-family home, pre-fabricated residence, houseboat, or even a condo. Also, collaboration with an Energy Trust-vetted solar trade partner is a requirement. One last criterion is that your yearly gross income must not surpass the program threshold according to your household size.
|Household Size||Maximum Gross Annual Income|
The rebate value hinges on the installed solar energy system’s size, with a top limit of $1.40 per watt and an overall incentive limit of $8,400 per residence.
|Portland General Electric||$1.40/watt||$8,400 maximum incentive per home|
|Pacific Power||$1.00/watt||$6,000 maximum incentive per home|
Undoubtedly, the Sunlight Within Reach program brings the dream of solar energy closer to reality for many Oregon residents!
ODOE Rebate for Solar and Battery Backup Systems
Let’s shine some light on another impressive initiative – the Oregon Department of Energy (ODOE) Solar and Battery Backup Systems Rebate Program. Its mission? To lighten the financial burden of installing either standalone solar energy systems or combined energy storage systems (home solar power coupled with battery backup). This rebate can shoulder up to 60% of the net cost of installation, with a maximum of $5,000 for exclusively solar systems and $7,500 for solar plus battery systems.
To qualify, the installation site must be nestled within the beautiful state of Oregon and achieve at least a 75% score on the total solar resource fraction rating, which assesses the volume of sunlight the system will soak up. All project components must be purchased from and fitted by an ODOE-certified contractor.
Here’s the rundown on the rebate calculation:
|Customer Type||Rebate Calculation|
|Low- or moderate-income homeowners||$1.80 per watt (DC) of installed capacity, up to 60% of the net cost* or $5,000, whichever is less.|
|Homeowners not considered low- or moderate-income, but eligible for an electric utility incentive||$0.20 per watt (DC) of installed capacity, up to 40% of the net cost or $5,000, whichever is less.|
|Homeowners not considered low- or moderate-income, and not eligible for an electric utility incentive||$0.50 per watt (DC) of installed capacity, up to 40% of the net cost or $5,000, whichever is less.|
So there you have it! The ODOE Rebate for Solar and Battery Backup Systems makes transitioning to solar energy more accessible for the sunny people of Oregon.
30% Federal Solar Tax Credit
Great news for sunshine lovers! Thanks to the Inflation Reduction Act of 2022, the 30% federal tax credit for solar panel installations is extended all the way through to 2032. After that, the credit doesn’t just disappear but gradually tapers down to 26% in 2033, 22% in 2034, and phases out entirely in 2035, unless Congress decides to gift us another extension.
Let’s break down the Investment Tax Credit (ITC). Essentially, it’s a 30% credit on the total cost of your solar installation, which comes back to you in the form of federal tax credits. If your tax credits surpass your tax liability, don’t worry. The remaining credits will simply be rolled over into the following tax year.
Here’s how it works in practice: Imagine that the cost of installing your solar system is $20,000. With the ITC, you’ll be able to deduct 30%, or $6,000, from your federal taxes. If your federal tax bill is $4,000, you’d use up that amount from the $6,000 credit, leaving you with $2,000 to carry over to the next tax year.
To illustrate the timeline, let’s lay it out in a table:
|Year||Federal Solar Tax Credit|
|2035 onwards||Phased out|
The federal solar tax credit makes investing in solar energy not just an environmentally conscious decision, but also a smart financial move. Enjoy the sunshine, Oregonians!
Oregon Net Energy Metering (NEM)
Net energy metering is a program that allows you to sell surplus energy generated by your solar panels to the grid in exchange for credits on your utility account. This policy can save you money and shorten the payback period for a solar energy system.
What is Net Energy Metering (NEM)?
- Power Trading: Net Energy Metering is an arrangement where homeowners with solar panels can “sell” their excess generated electricity back to the power grid. Think of it as a type of power trading, where you only pay for the “net” amount of electricity you use.
- Energy Credits: For every excess kilowatt-hour of electricity your solar panel system generates and feeds back into the grid, you earn an energy credit. This means you’re essentially banking the power you don’t use immediately for use later on.
- Utility Bills: These energy credits translate into savings on your utility bills. If you produce more power than you consume, the excess is credited to your account, effectively reducing your future power bills.
- Two-way Meter: The key to NEM is the two-way electricity meter. This device measures the electricity you draw from the grid and the surplus power your solar panels send back to the grid.
- Solar Energy Storage: Even when the sun isn’t shining, you can draw upon your bank of energy credits, making the energy you’ve generated with your solar panels on sunny days work for you at night or during cloudy weather.
- Economic Benefits: By providing homeowners with a financial incentive, NEM programs like the one in Oregon, promote the use of renewable energy and accelerate the payback period for solar energy system installations.
Remember, net metering policies can vary from utility to utility slightly. With NEM, your journey to energy independence can also lead to significant cost savings, making it a win-win deal for you and the environment!
Oregon Solar Panel Costs
As a rule of thumb, the average cost of solar panels before incentives is around $2.50 to $3.50 per watt. Given that the typical home solar panel system size is about 6 kilowatts (kW), we can estimate a gross cost range before incentives.
|System Size (kW)||Cost Range (before incentives)|
|3 kW||$7,500 – $10,500|
|4 kW||$10,000 – $14,000|
|5 kW||$12,500 – $17,500|
|6 kW||$15,000 – $21,000|
|7 kW||$17,500 – $24,500|
|8 kW||$20,000 – $28,000|
|9 kW||$22,500 – $31,500|
|10 kW||$25,000 – $35,000|
It’s important to remember that these costs are offset by federal and state incentives, reducing the net cost of the system significantly. In addition, you’ll see savings on your energy bill that will contribute to the overall return on investment. When considering solar panels in Oregon, it’s clear to see that the benefits are worth the initial costs!
Real World Example
Imagine you’re a homeowner in Portland, Oregon, and you decide to install a 6-kilowatt (kW) solar panel system on your roof. On average, the cost of this system might be around $15,000 before incentives. With the current incentives, rebates, and tax credits available in Oregon, you could potentially reduce this upfront cost by up to 50%.
Now, let’s calculate your potential savings:
- Incentives: The Energy Trust of Oregon might offer an incentive of $500. If you qualify for the Solar Within Reach program, you might receive an additional $1.40 per watt, totaling $8,400.
- Federal Tax Credit: The Investment Tax Credit could reduce your federal tax liability by 30% of the cost of your solar system. For our $15,000 system, that’s a reduction of $4,500.
After these deductions, your total out-of-pocket cost is only around $1,600. With the average annual energy bill in Portland being about $1,200, your solar panels could essentially eliminate your energy costs.
This means that your Oregon solar panel system could pay for itself within less than two years, and then continue to generate ‘free’ electricity for you for the next 20-25 years. This is a clear example of the fantastic ROI potential of solar energy systems, thanks to the great incentive programs in Oregon and the long-term energy savings they provide!
However, we highly recommend you get a quote because this example is a near-perfect one. An installer will come to your property and access it giving you a more true cost and ROI on your investment.
Is Solar Worth It In Oregon?
Let’s dive into whether solar energy is worth it in Oregon, considering all the factors involved.
To start, let’s examine the initial costs. As of 2023, the average cost of a solar panel system in Oregon is about $2.50 per watt. If you’re installing a standard 6 kW system, you’re looking at an initial investment of about $15,000. This might seem steep, but with incentives and energy savings, the real cost comes down significantly.
|Solar System Size||Average Cost|
Next, let’s factor in the Oregon Department of Energy (ODOE) rebate. If you’re a homeowner who’s not considered low or moderate income and you’re eligible for an electric utility incentive, you’ll get a rebate of $0.20 per watt. That’s a saving of $1,200 on your 6 kW system!
Now, don’t forget about the Federal Solar Tax Credit! You’ll get a 30% tax credit on the cost of your solar installation. This credit applies to your post-rebate cost, bringing your total cost down by $4,140.
|Federal Solar Tax Credit||Savings|
Adding in the savings from these incentives, your net cost for the solar system is just under $9,660. But we’re not done yet!
Once installed, your solar panels will begin generating free electricity. If your system generates more power than you use, Oregon’s net metering policy allows you to sell that extra power back to the grid, earning you credit on your electricity bill. In Oregon, the average electricity rate is $0.12 per kWh. If your 6 kW system generates around 7,000 kWh per year, you could save about $840 annually.
|Annual Energy Savings||Amount|
Over 25 years, which is the average lifespan of a solar panel, you could save a whopping $21,000!
|Total 25-Year Energy Savings||Amount|
|25 Years @ $840/Year||$21,000|
Summing it all up, your total net cost after the initial 25 years would be a negative value, meaning you come out $11,340 ahead.
|Initial System Cost||$15,000|
|Federal Solar Tax Credit||-$4,140|
|25-Year Energy Savings||-$21,000|
|Net Cost Over 25 Years||-$11,340|
With these substantial savings, in addition to helping the environment and increasing your property value, the question isn’t “Is solar worth it in Oregon?”, but rather, “How quickly can I go solar in Oregon?” The sunny future is looking bright!
