Factors that Affect Solar Panel Costs in Watertown

There are several criteria that can play into your installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that does the installation.

Solar Equipment

The cost of solar panel systems varies by thousands of dollars due to a variety of factors. One of the major factors is the system size, which is measured in kilowatts (kW). Solar power systems that have better efficiency or power production use better technology and/or more equipment, both of which can increase costs. For each additional kilowatt you need, your cost can go up by about $3,580.The solar equipment you choose can increase or decrease your cost by thousands or even tens of thousands of dollars. If you opt for the most efficient solar panel brands, you’ll end up paying more upfront than if you opted for the most affordable panels. On the other hand, higher efficiency could save you more over time on your energy bills. In addition, extra products, such as solar batteries, can bring your total well above the Watertown average.

Solar Financing Terms

Most solar companies in Watertown offer solar loans, which reduce your upfront costs of installing solar.It’s a good idea to factor the interest you’ll pay in your final cost estimate. If you can afford to pay a higher down payment, you can reduce your total costs and the amount of time it’ll take to pay off the loan.

Solar Panel Installation Company

The solar installer you choose will influence your total cost to make the switch to solar energy. Different companies will bill different amounts for the equipment and labor.Companies that only sell products with high efficiency and therefore a higher price point — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come at a higher cost. It’s best to do some research and decide on the company that offers the products, warranties and services you’re looking for and also fits within your budget.

How to Save on Solar Panels

There are a lot of solar installers to choose from, all of which offer different warranties, solar panel models and price points. To help you pick the right company for you, here are some tips to keep in mind:

  • Contract: Look through the contract terms thoroughly to make sure you understand the overall cost, completion timeline rebates and warranties.
  • Warranty: If you’re worried about the longevity of your solar system, verifying that your installer offers a 25-year, all-inclusive warranty can help put you at ease.
  • Solar Panel Brands: Homeowners will have different preferences for panels depending on their locations and how much efficiency they need. Although there are many options for which kind of solar panel you can get, not every company will have access to the exact one you may want or need, so be sure to ask for their list of offerings before making your decision.
  • Installation Process: Get details from your solar company about the installation process and what to expect, such as when the site survey will be done and what the project timeline is.

EcoWatch's Watertown, SD Solar Cost FAQs

What is the average cost of installing solar panels in Watertown?

This is a difficult question to answer exactly, because the cost depends on many factors. Broadly speaking, it costs about $17,900 for a 5-kW system and $35,800 for a 10-kW system after the ITC is applied. It will cost more if you want extra solar equipment or higher quality panels, or if you have above-average energy needs. On the other hand, you can spend less if you opt for a smaller solar panel system or less efficient solar panels.

Is cost the most important consideration when buying solar panels?

The upfront cost is a very important factor to consider, but whether it’s the most important for you depends on your reasons for going solar. In areas 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.

Is switching to solar power worth it?

Whether or not solar panels are worth it depends on some different factors like how much you pay for electricity and the amount of direct sunlight your roof gets.

How often do you have to replace solar panels?

Even 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 how much energy they produce will have decreased significantly after that point. You can choose to replace them once you've had them for that long or you can keep using them at a lower efficiency.
