Factors that Affect Solar Panel Costs in Harpswell

The cost of installing a solar system in Harpswell can vary by more than $10,000 from home to home. Your actual cost is determined by several factors. The biggest one is the size of the system your household needs, and other factors include equipment choices, financing options and the solar company you choose.

Solar Equipment

When it comes to estimating the price of solar panels in Harpswell, one of the most important factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are mainly based on your home's energy consumption, which you can gauge by looking at past energy bills. Your total cost can increase by around $2,830 for each additional kilowatt you need. The brand of solar panels and equipment you want is another factor that will largely affect costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to come at a higher price. Moreover, solar equipment consists of more than just the solar panels themselves. You'll also need to make decisions about the kind of racks used to mount the panels, inverters, solar batteries, etc. It's important to take all of this into consideration when looking for a solar system that's in your budget.

Solar Financing Terms

Solar panels can save you money on power bills over time, but they can also be a big investment. That's why many Harpswell homeowners decide to finance their solar panel systems to make paying for solar more affordable. It's a good idea to add the interest you'll pay in your final cost estimate. If you can afford to pay a larger down payment, you can reduce your total costs and the amount of time it'll take to pay back the loan.

Solar Panel Installation Company

A final factor to consider when trying to estimate the cost of solar for your home or business in Harpswell is the company you choose to install your solar system. Similar to choosing a company to build a deck or pool, for instance, there are plenty of solar installers that provide a range of services at different costs. Some companies 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 with an above-average cost. It's best to do some research and choose a company that offers the products, warranties and services you want and also fits within your budget.

How to Save on Solar Panels

There are many companies to choose from in Harpswell, and some homeowners feel overwhelmed considering their options. Selecting the right company for you can be difficult, so here are some tips to help you decide:

  • Contract: Review the contract terms carefully to make sure you understand how much it will cost, project timeline rebates and warranties.
  • Solar Panel Brands: Homeowners will have different preferences for panels based on their locations and how much efficiency they need. While there are many options for which model of solar panel you can get, not every company will have the exact one you may want or need, so be sure to peruse their list of offerings before deciding.
  • Installation Process: Make sure you're on the same page with the company with regard to how the installation process will go and what needs to be done before your solar panels are installed, such as updating your electrical system or roof.
  • Warranty: Warranties that provide coverage for replacement parts and repairs over a long period of time such as 25 years are the best you can get in the business, and offering that kind of warranty is one sign of a quality company.
