Factors that Affect Solar Panel Costs in Lisbon

There are a number of factors that can influence your solar panel 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 notable factors is the system size, which is measured in kilowatts (kW). Solar power systems with greater efficiency or power generation 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 $2,800. There are many different solar panel brands and the one you pick also changes the cost. Typically, the brands that offer higher efficiency tend to also be more expensive. Plus, the type of equipment you're looking to get can affect your total cost. If you just need panels, your system will be much less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

If paying for a solar system in cash is out of reach, solar loans are a solid route because they cut back your upfront costs and let you pay for your system over five to seven years on average. You'll have to consider the long-term cost of financing options, 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 principal cost. Making a larger down payment or securing a solar loan with a low interest rate could reduce your costs remarkably.

Solar Panel Installation Company

The solar installation company you select will impact your total cost to go solar. Different companies will bill different amounts for the equipment and labor. Additionally, some companies in Lisbon are more knowledgeable about local solar incentives and can help you make good use of additional rebates or tax exemptions. However, they may charge more for that service. Even if they cost more upfront, they could end up saving you more money in the long run.

How to Save on Solar Panels

The solar company you opt for will affect not only your total costs, but also the kinds of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are some important things you should keep in mind, including:

  • Warranty: A comprehensive, long-term warranty can help keep your solar panels running for years to come and save you money on part replacement and repairs.
  • Contract: Before you sign a contract with a solar company, make sure to look it over completely so you understand the terms. Also, ask questions if you aren't sure about some of the terms, such as what to do if a part breaks or malfunctions and if there are any guarantees about energy production.
  • Installation Process: Homeowners should make sure they know how exactly the installation process will go, as well as important factors like the completion timeline.
  • Solar Panel Brands: Not all solar companies offer the same brands of solar panels, so the brand and type of panel you want can play a substantial role in the company you opt for.

EcoWatch's Lisbon, CT Solar Cost FAQs

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

This is a difficult question to answer precisely, because the cost depends on a few different factors. Generally speaking, it costs about $14,000 for a 5-kW system and $28,000 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 usage. On the other hand, you can spend less if you go with a smaller solar panel system or cheaper solar panels.

Should I lease or buy solar panels in Lisbon?

Leasing solar panels can be an appealing choice, as it often comes with low or $0 upfront payments. The drawback is that you won't be able to save as much. If you lease, you don't own the system, so you can't claim any tax rebates and credits and your home value won't increase. Buying solar panels is a better option if you want to maximize your savings.

Is switching to solar power worth it?

Solar panels can be a good investment for lots of homeowners, but they might not be worth it for everyone. If your home doesn't get enough sunlight and/or your power bills are already reasonably low, solar panels might not be for you.

What solar power system size is right for my home?

The exact number of solar panels you need depends on your household energy consumption and the amount of sunlight your roof gets. You can take a look at your energy bills for the past year to get an idea of the solar system size you'll need. The average household has to buy between 20 and 35 panels to account for their typical energy usage.
