Solar panels in Seattle are surprisingly reasonable at about $2.50 to $2.60 per watt. Most of the time, solar panels come in 250 watts, which is the industry standard size, which means you’re going to end up needing 20 to 28 panels to be completely independent of the grid. The end result means you’ll end up paying something between $12,500 and $18,500 to power an average household. This of course will differ from user to user, based on a lot of factors- everything from how much hot water you use to what temperature you prefer to keep your house at. This cost will also be lowered substantially by various rebates, tax incentives and other little bonuses we’ll talk about later. So keep reading!

Washington is a great state to go solar in, and a big part of that is the incentives that the state provides for customers who want to do it. Below is a short breakdown of some of the big incentives that are available for those interested in going solar:

Most homes require somewhere between 6 kw and 8 kw of power to be self-sufficient. This comes out to between 24 and 32 solar panels. The amount of power you’ll need will vary from person to person however, largely based on your own personal preferences- hot water usage, preferred temperature, etc, not to mention the number of people living in the home.

How much do solar panels cost in Seattle, Washington?

In almost every case, solar panels are warrantied by their manufacturer for 20-25 years, so in the case of a manufacturer’s defect or similar flaw, they can be replaced. Similarly, most solar installation companies offer warranties, quite often of the same length as those of the manufacturer- 20-25 years. Therefore, it is very reasonable to assume that your solar panels will last at least a similar length of time. Once again, if your solar panels pay for themselves in as little as 15 years, then you’re looking at at the very least 5 to 10 years of “free” electricity, with a possibility of more afterward.

So if you’re looking into solar panels, it’s a good idea to know at least a little about the different kinds that are available, since one or the other may suit your needs better than the rest.

So first up, let’s talk about panels. Obviously these are the key to any solar energy system, as they collect the sunlight that will be converted into electricity. Simply stated, there are two basic kinds that are readily available for use in home systems- Polycrystalline panels and monocrystalline panels. Essentially, what this boils down to is that monocrystalline panels are smaller, more efficient and can operate with less direct sunlight than others, but they also tend to be more expensive, so a lot of homeowners will look past them. Polycrystalline panels on the other hand are the bigger ones, the kind that as often as not are installed on the ground due to their size. They are less efficient and require direct sunlight to operate at any large capacity, so they are not feasible in some situations.

What incentives are there for going solar in Seattle?

Your inverters are the devices that actually turn the captured sunlight into usable electricity, and the kind you get are largely going to be dictated by the type of panels you use and their placement. So there’s really not much to worry about here. Suffice it to say, there’s three major types- string inverters, microinverters and power optimizers. String inverters are the most common type used in home installations as they tend to be the cheapest and most flexible kind.

So it rains a lot in Seattle, right? Everybody who ever listened to grunge rock knows that. But how does weather affect your solar panels? Let’s take a look at some common weather conditions and see.

Rain: Believe it or not, a little rain is actually good for your solar panels. It helps wash the dust, grime and other assorted accumulations that tend to build up on them over time, especially if they’re place on a rooftop. So rain is actually a positive.

How Much Solar Power Do I Need?

Clouds/Fog: Unfortunately, the cloud cover associated with rainfall is bad for your panels in the sense that the less sunlight that gets to them, the less electricity they will produce. Same goes for dense fog. Your panels can produce up to 70% electricity on an overcast day than a sunny one.

Snow: Snow is bad for solar panels mainly because any significant accumulation can completely block the sunlight reaching your panels, which in turn completely stops your production of electricity. The snow itself is not damaging however, but if you’re able you may want to have a plan to remove the snow from your panels when it gets built up or you could be without solar energy till it melts. And that could be a while.

Temperature: Sunny weather and high temperatures mean more solar power, right? Sort of. Sunny is great, but higher temperatures actually reduce the efficiency of your panels by an estimated 1% for every degree they rise above 77 fahrenheit. Lower temperatures, however, actually increase the efficiency of your panels up to a point, so the optimal weather for solar panels is a bright sunny day in the 50s. Seattle of course doesn’t get a ton of those, but you can always hope.

How long do solar panels last?

As with any major investment, you’re going to want to do your research before dropping a lot of money on a solar panel system, and the internet gives you an outstanding resource to this end. Here’s just a few things to look for when considering a solar company:

Time in the industry: Just like in any other industry, the longer a company has been in operation, the more reliable they are likely to be. Furthermore, companies that stay in business for a long time tend to be the ones that keep good relationships with customers and therefore have good word-of-mouth advertising. This doesn’t mean new companies can’t do a good job, it’s just a little more comforting to know someone has been doing this for 20 or 30 years and hasn’t gotten sued out of existence yet.

Types of Panels: So believe it or not, some companies don’t like to work with certain types of panels. As a result, if you think you’d prefer to use a certain kind of panel or definitely don’t want to use one kind, you might want to check with your solar company and make sure they are comfortable working with your preferred panels.

Types of Panels & Inverters

Payment Options: So obviously this is going to be an investment, and there’s going to be a substantial cost associated with it before you receive any kind of rebates or credits. So how are you going to pay for this? Some people may be able to just write a check  for the full cost and call it a day, but that’s not an option for the vast majority. So you’re more than likely going to need some kind of financing. Some companies will offer some form of in-house financing, but most are going to leave it up to you. Either way, just be aware of what’s going to be expected of you payment-wise before making any decisions.

Warranties: Your solar panels will more than likely come with a warranty of some variety, usually 20-25 years, which means the company itself will repair or replace your panels if they malfunction due to a manufacturer’s error. Your solar company quite often will have a similar warranty, often guaranteeing their work for 20-25 years with the promise that they will fix anything that comes up due to an installer’s error. However, make sure you read the fine print- many companies will ask for service charges and other fees when you ask them to honor their warranty. So just make sure you know what you’re getting into before you sign anything so you don’t end up with any nasty surprises when you need some work done.

Reviews: Probably the most important thing to consider is any reviews you can find online. Customers online tend to be brutally honest- if they’re not completely and 100% satisfied with a company, they’re gonna let you know about it. So by all means, scour the internet and find out everything you can about a company before making any commitment.
