Factors that Affect Solar Panel Costs in Lafayette

Cost is typically one of the most important factors for homeowners who are considering investing in solar. There are a few key factors that determine your overall cost in Lafayette: solar equipment and system size, financing options and the solar installation company you choose. We'll go over each of these briefly below.

Solar Equipment

One of the most important factors to consider when it comes to the cost of going solar is the size of the solar system, which is measured in kilowatts (kW). The more electricity your household uses, the larger your system will likely need to be. You can expect to spend about $2,730 per kilowatt in Lafayette. The solar equipment you choose can increase or decrease your cost by thousands or even tens of thousands of dollars. If you get the most efficient solar panel brands, you'll end up paying more upfront than if you opted for the most affordable panels. On the other hand, more efficient panels could save you more over time on your power bills. In addition, extra products, such as solar batteries, can bump up your total well above the Lafayette average.

Solar Financing Terms

Solar panels can save you money on utility bills over many years, but they can also be a big investment. That's why many Lafayette homeowners opt to finance their solar panel systems to make paying for 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'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 APR could reduce your costs remarkably.

Solar Panel Installation Company

A final consideration when trying to estimate the cost of solar for your home or business in Lafayette is the company you hire to install your PV system. As with choosing a company to build a deck or pool, for example, you'll have no shortage of solar installers that provide a range of services at different price points. Additionally, some companies in Lafayette know more about local solar incentives and can help you take advantage 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.

How to Save on Solar Panels

There are numerous companies to choose from in Lafayette, 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:

  • Reputation: Make sure your solar system installer has a good reputation by confirming it has certifications and licenses, checking how long it's been in business and reading reviews by past customers and solar experts like the EcoWatch team.
  • Warranty: Companies typically offer different kinds of warranties that provide different kinds of coverage. A 25-year, all-inclusive warranty is the gold standard.
  • Contract: Though reading through a contract can take a lot of time, it's important to do it thoroughly so you can make sure you understand what services your solar company will provide and the terms of the warranty.
  • Solar Panel Brands: Each solar panel brand and type has varying levels of quality, durability and efficiency. They will come at different costs as well. The company you choose has an impact on which solar panel brands you have access to.
