Factors that Affect Solar Panel Costs in Port Washington

Cost is often one of the most important factors for homeowners considering investing in solar. There are a few key factors that affect your total cost in Port Washington: solar equipment and system size, financing options and the solar installation company you choose. We’ll go over each of these briefly below.

Solar Equipment

One of the most important factors to consider when it comes to the cost of going solar is the size of the solar system, which is measured in kilowatts (kW). The more energy your household consumes, the larger your system will likely need to be. You can expect to spend around $3,880 per kilowatt in Port Washington.The type of solar panels and equipment you want is another factor that will considerably impact costs. Solar panels that are more efficient, like monocrystalline panels, tend to cost more. Moreover, solar equipment goes beyond just the solar panels themselves. You’ll also need to consider the kind of racks used to mount the panels, inverters, solar batteries, etc. It’s important to take all of this into consideration when researching a solar system that falls within your budget.

Solar Financing Terms

Solar panels can save you money on power bills over many years, but they can also be a significant investment. That’s why many Port Washington homeowners opt to finance their solar panel systems to make paying for solar more affordable.You’ll have to consider the long-term cost of financing options, including the total interest you’ll pay over the length of the loan. If you’re only able to get a high-interest loan, then your total can be hundreds or even thousands of dollars above the equipment and labor cost. Making a larger down payment or getting a solar loan with a low APR could reduce your costs considerably.

Solar Panel Installation Company

The solar company you choose will affect your total cost to adopt solar energy. Different companies will charge different amounts for the equipment and labor.The company’s size can sometimes play the most significant role in the installation costs. Larger national companies, like SunPro and Sunrun, often have lower pricing because of access to greater resources and better pricing. Smaller local companies might be more costly, but they generally have better customer service and more customization options, and the occasional sale or discount can bring their pricing lower to compete with bigger names.

EcoWatch's Port Washington, WI Solar Cost FAQs

How much does it cost to install solar panels in Port Washington?

The average cost of solar panels in Port Washington is about $19,400 for a 5-kW system and $38,800 for a 10-kW system before the ITC, but the actual cost will depend on stuff such as the type of solar panels you want, what size system you need and how much energy you consume.

Is cost the most important thing to consider when buying solar panels?

Cost is a key factor to consider, but whether it’s the most important for you depends on why you decided to go solar. In places where rooftop space is limited, efficiency can be more important than the cost. Other factors that are important to consider are the quality and durability of your solar panels.

Does Port Washington have a net metering program?

Most states have net metering programs of some kind. Through these, you can either get paid for the extra power your system produces or or receive credits to put toward future utility bills. Currently there are just three states that don’t have any net metering laws: Alabama, Tennessee and South Dakota.

How long do solar panels last in Port Washington?

Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable at that time. What this means is their energy production will have decreased significantly after that point. You can opt to replace them once you've had them for that long or you can continue to use them at a lower efficiency.
