Pros and Cons of Solar in Washington

Unfortunately, nothing is perfect - including solar. To avoid buyer's remorse, you should think about all the pros and cons associated with installing solar equipment on your home. Then weigh them against each other to decide if it makes sense for you.

Everyone has their own opinion on how to interpret and weigh the pros and cons against each other. Our goal is to present the most common pros and cons and let you make your own choice.

Washington Solar Pros

  • Cost Savings: Reduce or eliminate electric bills
  • Energy Independence: Generate your own electricity to reduce reliance on the grid
  • Sustainability: Reduce your carbon footprint
  • Home Value: Increase home value (4.1% on average)
  • State Incentives: Washington offers a Solar Production Incentive that pays homeowners for the electricity they generate.
  • Net Metering: Washington has a net metering policy, allowing you to sell excess electricity back to the grid, which can offset your energy costs.
  • Community Solar: For those who can't install solar panels, Washington offers community solar programs where you can buy into a larger solar array and receive credits on your electricity bill.

Washington Solar Cons

  • Compatibility: Not viable for all roofs or homes
  • Upfront Costs: The initial cost of the system, including Installation costs can be steep.
  • Variable Generation: The amount of electricity produce by the panels is of course determined by how much sun you get. Sunnier days get more power.
  • Financial Liability: If you sign into a solar lease contract, make sure you read the fine print. There have been cases of customers being responsible of more than they thought.
  • Efficiency Factors: The efficiency of your solar setup can be affected by various factors like the angle and orientation of your roof, and the amount of sunlight your location receives.
  • Policy Changes: While current incentives are attractive, changes in state or federal policies can affect the long-term savings. 
  • Savings vs Other States: While solar can save you money, the savings might not be as high as in states with higher electricity costs.

EnergyBot's Take

Weather in Washington is probably the biggest factor when considering solar. Western Washington is significantly cloudier than Eastern Washington. Which is why Washington ranks 34th in the national solar ranking. While it’s not the best, there are still some things to consider. 

Let’s consider the financials. The average life expectancy of solar panels is 20 to 25 years. And even after that they often can still produce power, just not as efficiently. Solar panel technology is also becoming better at producing power during less sunny days. With that in mind, the average payback ranges from 8 to 12 years, depending on where you live and your house conditions. You’ll also have to consider roof structural strength, orientation, and angle. 

Washington also offers various state incentives including net metering and community solar programs. These advantages make a compelling case for solar adoption, especially when you consider the positive environmental impact and the potential to increase your home's value.

If you are on the fence you can use this tool to get an accurate cost breakdown for your home based on your historical energy usage.

Leasing vs Buying Solar Panels in Washington

There are several ways you can purchase and/or finance your solar panel installation in Washington. Your goals and financial situation will dictate which option is best for you.

Cash Purchase

The most straightforward option. You pay upfront for the entire cost of the rooftop solar system. No interest, and fewer headaches, but many people are hesitant about spending several tens of thousands of dollars out of pocket.

Solar Loan

The most common method for buying solar systems. Like many other types of large purchases, you can finance your solar system through a bank or solar loan provider.

This sounds great, and many other solar loan salespeople will leverage the low payment to justify the costs. You will likely hear something like "You pay $250 a month on your electric bill, with a solar loan you will pay $200 and have free electricity."

Do your due diligence before you sign on the dotted line. There are many horror stories of variable loan terms, ballooning interest rates, and harsh missed payment penalties.

Solar Lease

Leasing solar panels generally involves less money out of pocket upfront. But, it's important to note - you do not own your solar energy system. You essentially renting the solar system. A solar provider will install the equipment and charge you a fixed monthly fee.

Most solar lease contracts last for a couple of decades, during which time the provider will keep an eye on the system's hardware and performance. At the end of your lease, you can choose to:

  • Renew your lease agreement
  • Purchase the system
  • End your lease agreement

Solar leases can be complicated. Not all are bad, but in many cases the lease terms in not in favor of the buyer. Before you decide on a solar lease make sure to read your contract thoroughly. If you don't understand something, ask an expert.

Power Purchase Agreements

A power purchase agreement (PPA) is a financial agreement where a solar company will design and install a solar system on your home or business with little or no cost upfront. Instead of paying a monthly fee like a lease, the agreement includes a fixed price per kilowatt-hour (kWh) of electricity generated.

For example, you agree to pay $0.12 per kWh of electricity generated for the next 20 years. The solar company will install and maintain your system and sell the power back to you that you use. They may also collect payment for any additional energy they put back into the grid.

Just like a lease, you do not own the panels. When the contract is up, they will either be removed or your contract may have other terms for you to buy or renew your power purchase agreement.

Power purchase agreements can be complicated. Before you sign make sure you review the contract and if possible have an expert in power purchase agreements review the details.

Washington Solar Incentives

Don’t forget about Solar Incentives! While there is the Federal 30% Tax Credit that came from the Inflation Reduction Act, there may be others that are statewide or local.

Check to see if you are eligible for solar incentives, they could significantly reduce the cost of solar panel installation. While some incentives are statewide, others are more local. Your city, utility, or other local company could offer hundreds or thousands of dollars in incentives to install solar systems.

This table shows the available incentives in Washington. But hey, this isn't the end-all-be-all list. Check with your local utility for other potential incentives.

We believe comparing these three names in the solar industry will give you the info you need to decide if solar panels are right for you.

Before You Install Solar Panels

Just because solar is a popular discussion right now, doesn’t mean it makes sense for everyone. It is still a large and expensive decision. Installing solar has great financial and environmental benefits but it won’t feel beneficial if you run into issues. Along with studying a 20-year cost comparison for your home, read some more tips to keep in mind when mulling over your decision on your installer, system design, and financial plan.

  • What are the long-term savings and payback period for installing a solar panel system?
  • How will installing solar panels impact my home's value?
  • What is the system’s Return on Investment (ROI)?
  • Are there any specific design or aesthetic considerations for solar panel installation?
  • How do I weigh the environmental benefits against the costs of installation?
  • What are the specific terms and conditions for the installer?

Technology’s Assistance in Solar Planning

Washington and Oregon are utilizing interactive mapping tools to identify the best locations for solar farm development. Their aim is to be proactive in their planning by involving the community early. Their hope is this will both minimize conflicts with local communities, farmers, and wildlife, and help projects get built more quickly. 

The mapping tools are helping developers pinpoint the best locations. This approach not only speeds up the transition to renewable energy but also takes into consideration the long-term impacts on various stakeholders.

It is important to note that while these mapping tools are a valuable resource, they still don’t solve everything. They currently lack information on culturally sensitive areas and tribal lands. Additional on-the-ground surveys and community engagement are still necessary. 

Despite these limitations, the mapping initiative is a significant first step in creating a more streamlined and conflict-free process for solar development, ultimately contributing to the states' carbon-free electricity goals. Maybe more states will follow Washington’s lead.

Washington Solar FAQs

The cost of solar panel installation in Washington can vary significantly based on a number of factors, including the size and type of the system, the complexity of the installation, your solar installer, and the specific location. However, the average cost of solar panels in the U.S. was about $3.13 per watt, before any incentives or tax credits.

A typical residential solar system is usually around 8 kilowatts (8,000 watts), but varies based on energy use and the size of the house. The US average cost for a 6 kW system is $18,771 and the US average cost for a 10 kW system is $31,285, before incentives. The average price for a home solar panel system in Washington is $19,500 for a 6kW system or about or about $3.25 per watt.

The number of solar panels you would need depends on a variety of factors such as:

  1. Your home's energy consumption: The first step is to calculate your household's energy use. You can do this by looking at your electricity bills to see how much electricity you use in a year, usually measured in kilowatt-hours (kWh). The average U.S. home uses around 10,400 kWh per year, but this can vary widely based on the size of your home, the efficiency of your appliances, and your personal habits.
  2. The amount of sunlight your location receives: This can vary depending on where you live. For example, if you live in a place that has many sunny days like Arizona, you might require fewer solar panels compared to someone living in a place with less sunlight like Seattle.
  3. The efficiency of the solar panels: Not all solar panels are created equal. Some panels can convert sunlight into electricity more efficiently than others. On average, residential solar panels have an efficiency rating between 15-20%. The higher the efficiency, the fewer panels you would likely need to meet your energy needs.
  4. The size of the solar panels: Solar panels also come in different sizes. A common size for residential use is roughly 65 inches by 39 inches. Each panel typically produces around 250 to 400 watts of power, but this can vary.

To give you a rough estimate, let's say you live in a location that receives about 5 hours of peak sunlight per day, your solar panels have an efficiency of 20%, and each panel has a power rating of 300 watts. If your home uses about 10,400 kWh per year, you would divide this by 365 to get your daily energy use (about 28.5 kWh). You would then divide this by the hours of peak sunlight (5 hours), to get your required power output per hour (about 5.7 kW). If each solar panel produces 300 watts (or 0.3 kW), you would divide 5.7 kW by 0.3 to get the number of solar panels you need, which would be about 19 panels.

  • Lower Electricity Bills:
    Once your solar panels are installed, you can generate your own electricity and reduce your reliance on the grid, which can lower your monthly bills.
  • Environmental Benefits:
    Solar energy is clean and renewable, so using it helps reduce greenhouse gas emissions and other harmful pollutants.
  • Increased Home Value:
    Installing solar panels can increase the value of your home and make it more attractive to potential buyers.
  • Long-Term Savings:
    While the upfront cost of installing solar energy systems can be high, they can pay for themselves over time through lower energy bills and other savings.
  • Location:
    Homes in areas with lots of sunlight are generally better candidates for solar panels. If your home is shaded or doesn't receive much sunlight, it may not be the best choice.
  • Roof Orientation:
    Ideally, your roof should be facing south to get the most sunlight throughout the day.
  • Roof Condition:
    Your roof should be in good condition and able to support the weight of the solar panels. If your roof needs repairs or replacement, it's best to take care of that before your solar installation.

The installation process for solar panels can take anywhere from a few days to a few weeks, depending on the size of the system and the complexity of the installation.

Your installer should be able to give you an estimated timeline based on your specific project.

One of the great perks of solar panels is their low maintenance. However, to ensure they keep producing clean, green power, a few key maintenance steps are recommended.

  • Inspections: have your panels inspected every few years by a professional. This ensures they are operating at their peak performance.
  • Regular Cleaning: Dust, debris, and dirt can accumulate on your panels over time, affecting their efficiency. Consider giving them a gentle clean once a year to keep them in tip-top shape. 
  • Maintenance Services: Many solar panel installers offer maintenance services for an additional fee, saving you the hassle of DIY upkeep.

Another benefit of solar panels is their longevity. Most come with a 25 to 30-year performance warranty which spans their Effected Useful Life (EUL). While the EUL is supposed to give you an estimate of how long the equipment will last, solar panels often continue to produce power long past this timeframe, just not as effectively as they used to. However, with anything, it's crucial to delve into the fine print to understand precisely what's covered.

The inverter is a critical component that converts direct current (DC) from your panels into alternating current (AC) for your home. Inside the inverter are electro-magnetic parts that move quickly and often. Because they have these moving parts, inverters have a shorter lifespan than the panels themselves. Know ahead of time that you will have to replace the inverters at least once during the lifespan of your panels. This should be factored into your long-term cost considerations.

Great question! Some homeowner's insurance policies may cover solar panels, but it's wise to double-check. You might need to add a separate rider or explore different insurance providers to ensure everything is adequately protected.

While solar panels seem straightforward with no moving parts, taking on a DIY installation might not be the best choice for most homeowners. The primary challenges lie in the intricate electrical work. Mistakes can not only damage the expensive system but also pose safety risks, especially if you're not an electrician. Before attempting a DIY project, consider getting a professional quote. You might be surprised to discover that labor costs are a relatively small part of the overall expense.

When it comes to selecting the right solar panels for your home, you'll typically encounter two main types: Monocrystalline and Polycrystalline. Each has its pros and cons, making the choice a bit of a balancing act.

  • Monocrystalline panels are more efficient but come with a higher price tag.
  • Polycrystalline panels are slightly less efficient but are more budget-friendly.

Keep in mind that due to the efficiency difference, you may need a few more poly-panels to match the output of mono-panels. Additionally, various factors such as your roof's weight capacity, area, angle, orientation, and budget should influence your decision. To make an informed choice, it's best to consult a professional solar installer who can assess these factors and provide a tailored recommendation for your specific situation.

Instead of making a blind choice, consult with a solar installer who can assess various factors like your budget, location, and energy requirements. They can provide a tailored recommendation, ensuring you get the most efficient panels for your specific situation.
