Factors that Affect Solar Panel Costs in Lisbon

Cost is often one of the most important factors for homeowners considering investing in solar. There are a few major factors that determine your overall cost in Lisbon: solar equipment and system size, financing options and the solar installation company you choose. We’ll discuss each of these briefly below.

Solar Equipment

Solar system size, which is measured in kilowatts, is one of the largest factors that determines the overall cost of going solar. For that reason, it’s crucial to accurately ascertain the size of the solar energy system needed for your home by figuring out your energy needs.The model of solar panels and equipment you get is another factor that will substantially affect costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to cost more. Furthermore, solar equipment is more than just the solar panels themselves. You’ll also need to decide on 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 big investment. That’s why many Lisbon homeowners choose to finance their solar panel systems to make paying for solar more affordable.You’ll have to consider the long-term cost of loans, 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 more than the original cost. Making a larger down payment or securing a solar loan with a low interest rate could reduce your costs significantly.

Solar Panel Installation Company

The solar installer you opt for to handle your switch to clean energy can have an effect on your total costs. There are about 3 solar panel companies in Lisbon, and each can charge different amounts for labor and equipment.Companies that only sell high-quality, high-efficiency and high-price products — 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 go with the company that provides the products, warranties and services you’re looking for and also is within your budget.

  • Installation Process: Make sure you’re aligned with the company in regard to how the installation process will go and what needs to be done before your solar panel system is installed, such as updating or replacing your electrical system or roof.
