Factors that Affect Solar Panel Costs in Harpswell
Even though the average cost of a solar system in Harpswell is $10,380, your final cost may be higher or lower than that. There are quite a few factors that can have a major impact on the cost of a residential solar panel installation. Below are some of the more crucial things to take into consideration.
Solar Equipment
When it comes to estimating the cost of a solar energy system 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 determine by looking at past electricity bills. Your total cost can increase by around $2,830 for each additional kilowatt you need. Some solar panel brands — like Maxeon from SunPower — cost more upfront but also tend to offer better efficiency. In a city like Harpswell, where sunlight is relatively abundant, efficiency can quickly pay off. Plus, if you have a small roof or you don't have a lot of space for your panels, higher efficiency options will be a better option. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.
Solar Financing Terms
If paying for a solar system in cash is too expensive, solar loans are a popular option because they cut back your upfront costs and allow you to pay for your system over five to seven years on average. You'll have to consider the long-term cost of loans, including the amount of 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 more than the original cost. Making a larger down payment or getting a solar loan with a low interest rate could reduce your costs remarkably.
Solar Panel Installation Company
The solar panel installation company you pick will play a role in your total cost to adopt solar power. Different companies will charge different amounts for the equipment and labor. 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 at a higher cost. It's best to do some research and find a company that provides the products, warranties and services you're looking for and also is within your budget.

How to Save on Solar Panels
The solar company you go with will impact not only your total costs, but also the types of solar panel brands, warranties, and other equipment you can get. When choosing a solar company, there are a few important things you should take into account, including:
- Warranty: A high-quality company stands out from other companies by offering the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
- Contract: Though reading through a contract can take a lot of time, it's important to do it fully so you can be sure you understand how much the equipment and services will cost and how part repairs and replacements will be handled.
- Solar Panel Brands: Different companies have different brands and types of panels. If you prefer a specific brand, make sure the solar panel company you're considering has it.
- Installation Process: An important thing to understand when going solar is the installation process itself. Be sure to align on any details you need to know with your solar installer, such as what permits you should acquire and what the project timeline is.

EcoWatch's Harpswell, ME Solar Cost FAQs
What is the average cost of installing solar panels in Harpswell?
This is a difficult question to answer precisely, because the cost depends on a few different factors. Broadly speaking, it costs about $14,150 for a 5-kW system and $28,300 for a 10-kW system after the ITC is applied. You can expect to pay more if you want extra solar equipment or more efficient panels, or if you have above-average energy usage. Conversely, you can spend less if you opt for a smaller solar panel system or cheaper solar panels.
What other factors should I consider in addition to cost when buying solar panels?
The initial cost is a very important factor to consider, but whether it's the most important for you depends on why you decided to go solar. In areas where rooftop space is limited, efficiency can trump the cost. Other factors that are important to take into account are the quality and durability of your solar panels.
Does Harpswell have a net metering program?
Most states have net metering programs of some kind. Through these, you can be compensated for the extra power your system generates 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 Harpswell?
On average, the lifespan of solar panels is about 25 to 30 years. Some even last up to 50 years, but their efficiency goes down by about 0.8% each year. You can choose to replace them sooner if you want to maintain a larger level of energy production.
