Factors that Affect Solar Panel Costs in Costa Mesa

Cost is usually one of the most important factors for homeowners wanting to invest in solar. There are a few key factors that determine your overall cost in Costa Mesa: solar equipment and system size, financing options and the solar installation company you choose. We’ll cover each of these briefly below.

Solar Equipment

The cost of solar panel systems varies by thousands of dollars due to a variety of factors. One of the key factors is the system size, which is measured in kilowatts (kW). Solar power systems that have greater efficiency or power production use better technology and/or more equipment, both of which can raise costs. For each additional kilowatt you need, your cost can go up by about $3,470.Some solar panel brands — like Maxeon from SunPower — are more costly upfront but also tend to offer higher efficiency. In a city like Costa Mesa, where sunlight is 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

Solar panels can save you money on energy bills over time, but they can also be a big investment. That’s why many Costa Mesa homeowners choose to finance their solar panel systems to offset upfront costs.You’ll have to consider the long-term cost of financing options, including the total 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 more than the principal 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 green energy can play a role in your total costs. There are about 3 solar panel companies operating in Costa Mesa, and each can charge varying amounts for labor and equipment.Larger national companies usually have lower costs, but some local companies undercut them by promoting sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or add-on services like electric car charger installation, they might be cheaper overall.

How to Save on Solar Panels

There are many solar installers to choose from, all of which offer different warranties, solar panel models and price points. To help you decide on the right company for you, here are some tips to keep in mind:

  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a respected certification organization for sustainable energy professionals. If your solar panel installer is NABCEP-certified, it likely has a solid reputation and is qualified to get the job done well. Another way you can research your installer’s reputation is by reading reviews.
  • Warranty: If you care about the longevity of your solar system, verifying that your installer offers a 25-year, all-inclusive warranty can give you some peace of mind.
  • Solar Panel Brands: Different companies carry different brands and types of panels. If you know you want a specific brand, make sure the solar panel installer you’re considering has it.
  • Installation Process: Make sure you’re aligned with the installer regarding how the installation process will go and what needs to be done before your solar panel system is installed, such as updating your electrical system or roof.
