Factors that Affect Solar Panel Costs in Lisbon
Even though the average cost of a solar system in Lisbon is $11,856, your final cost may be above or below the average. There are several factors that can have a sizable impact on the cost of a residential solar panel installation. Below are some of the more crucial things to keep in mind.
Solar Equipment
System size, which is measured in kilowatts, is one of the largest factors that determines the overall cost of installing solar panels. That’s why it’s a priority to accurately gauge the size of the solar energy system needed for your home by figuring out your average energy use.The brand of solar panels and equipment you get is another factor that will greatly impact costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to be more pricey. Plus, solar equipment goes beyond 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 researching a solar system that’s in your budget.
Solar Financing Terms
For some homeowners, paying for solar panels out of pocket can be a challenge. Solar loans are offered by most installers in Lisbon, which can lower, or in some cases completely eliminate, your upfront costs to make solar more affordable.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 can only get a high-interest loan, then your total can be hundreds or even thousands of dollars above the equipment and labor cost. Making a larger down payment or finding a solar loan with a low interest rate could reduce your costs significantly.
Solar Panel Installation Company
The final key cost factor you should take into consideration is the installer you choose. Given the booming popularity of renewable energy solutions in Lisbon, you’ll have plenty of options to choose from, but each comes at varying price points for labor and equipment.Additionally, some companies in Lisbon have more knowledge about local solar incentives and can help you make good use of additional rebates or tax exemptions. Though, they may charge more for walking you through the whole process. Even if they cost more upfront, they could help you save more money in the long run.
