Factors that Affect Solar Panel Costs in California

The cost of installing a solar system in California can vary by more than $10,000 from home to home. Your actual cost is dependent on several factors. The largest one is the size of the system your household needs, and other factors include the equipment you choose, financing options and the solar company you choose.

Solar Equipment

The size of the solar system you need for your home, which is measured in kilowatts, is the most important cost factor to consider. For every additional kilowatt you need, your total will most likely increase by nearly $3,550. The brand and type of equipment you want for your solar system can raise or lower the price quite significantly. If you prefer a trusted brand name like Tesla or SunPower, these often come at a higher price 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 will be looking at a higher equipment cost, but this can typically lead to greater savings over time. Plus, if you want add-ons like an electric vehicle charger or solar batteries, this will also increase the cost.

Solar Financing Terms

Most solar companies in California provide solar loans, which reduce your upfront costs of installing solar.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 principal 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

Lastly, the company you choose to install your solar system can influence how much you pay. California’s solar companies all have different labor costs and add varying upcharges to equipment. The size of the company sometimes plays the most considerable role in the cost of installation. Larger national companies, like SunPro and Sunrun, often have lower prices because of more resources and bulk pricing. Smaller local companies might be more costly, but they generally have better customer service and more customization options, and the occasional sale or promotion can bring their pricing lower to compete with bigger companies.

How to Save on Solar Panels

The solar company you go with will affect not only your overall costs, but also the kinds of solar panel brands, warranties, and other equipment you can get. When choosing a solar company, there are some important things you should consider, including:

  • Warranty: If you’re concerned about the endurance of your solar system, ensuring your installer offers a 25-year, all-inclusive warranty can give you some peace of mind.
  • Solar Panel Brands: Different companies have various brands and kinds of panels. If you prefer a specific brand, make sure the solar company you’re considering has it.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a respected certification organization for renewable energy professionals. If your solar panel installer is NABCEP-certified, it likely has a good reputation and is qualified to do the job well. Another way you can verify your installer’s reputation is by reading reviews.
  • Installation Process: Make sure you’re aligned with the installer regarding how the installation process will go and what you need to do before your solar system is installed, such as updating or replacing your electrical system or roof.

EcoWatch's California, PA Solar Cost FAQs

Generally speaking, it costs about $17,750 for a 5-kW system and $35,500 for a 10-kW system after the ITC is applied. It will be more expensive if you want other solar equipment or higher quality panels, or if you have higher-than-average energy usage. On the other hand, you can spend less if you opt for a smaller solar panel system or less expensive solar panels.

Are solar panels free in California?

Solar panels aren’t free in California, but there are some options that can make getting them more affordable, such as leasing solar panels or getting a solar loan. There may also be local programs or incentives that can further reduce the cost.

Is switching to solar power worth it?

Whether or not solar panels are worth it depends on some different factors like how much you pay for electricity and how much direct sunlight your roof gets.

What solar power system size is right for my home?

To figure out what solar panel system size you need, you need to know how much energy your home needs and how much sunlight your home gets. For a general estimate, however, since each panel can usually produce about 250 to 400 watt-hours per hour, the average house will need 20 to 35 panels.
