Factors that Affect Solar Panel Costs in San Diego

For many San Diego homeowners, the decision to install solar panels comes down to cost. However, the range of solar installation costs can be quite wide in San Diego, with typical prices between $20,000 to $40,000. There are a few factors that greatly influence the price you'll pay, which we'll go over below.

Solar Equipment

System size, which is measured in kilowatts, is one of the largest factors that influences the overall cost of going solar. Because of that, it's crucial to accurately gauge the size of the solar energy system needed for your home by figuring out your typical energy use. The brand and type of equipment you choose for your solar system can increase or decrease the price quite significantly. If you prefer a trusted brand name like Tesla or SunPower, these are often more expensive than other brands. Efficiency also matters. Whether you're opting for high efficiency because you have a small roof or just want maximum energy production, you can expect a higher equipment cost, but this can typically lead to greater savings over time. Also, if you want extra equipment like an electric vehicle charger or solar batteries, this will also increase the cost.

Solar Financing Terms

Most solar installers in San Diego have solar loans, which reduce the initial cost of installing solar. 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're only able to 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 securing a solar loan with a low interest rate could reduce your costs remarkably.

Solar Panel Installation Company

The remaining key cost factor you should keep in mind is the installer you choose. Given the massive popularity of sustainable energy solutions in San Diego, you'll have many options to choose from, but each comes at various price points for labor and equipment. Additionally, some companies in San Diego know more about local solar incentives and can help you learn about additional rebates or tax exemptions. Though, they may charge more for that service. Even if they cost more upfront, they could help you save more money in the long run.

How to Save on Solar Panels

The solar panel company you opt for will influence not only your total costs, but also the types of solar panel brands, warranties, and other equipment you can get. When choosing a solar company, there are some important things you should keep in mind, such as:

  • Contract: Before signing a contract with a solar company, make sure to read it through completely so you understand the terms. Also, ask questions if you're not 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: Make sure you're on the same page with the installer regarding how the installation process will go and what you need to do before your solar panels are installed, such as updating your electrical system or roof.
  • Solar Panel Brands: Different companies will have different brands and models of panels. If you prefer a specific brand, make sure the solar company you're considering has it.
  • Reputation: Make sure your solar 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 EcoWatch.
