Factors that Affect Solar Panel Costs in San Francisco

There are several factors that can affect your total installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar system.

Solar Equipment

One of the most important factors to consider when it comes to the cost of adopting solar energy is the size of the solar system, which is measured in kilowatts (kW). The more energy your household uses, the larger your system will likely need to be. You can expect to pay about $3,470 per kilowatt in San Francisco.The brand of solar panels and equipment you want is another factor that will significantly affect costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to come at a higher price. Further, solar equipment is more than just the solar panels themselves. You’ll also need to decide on 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 falls within your budget.

Solar Financing Terms

Many homeowners find the average cost of solar in San Francisco to be prohibitively expensive, even if the investment pays off over time. Fortunately, almost every solar installer in the area provides financing options. Solar loans substantially decrease upfront costs in most cases, but they also lead to paying more over time because of interest.It’s wise to factor the interest you’ll pay in your final cost estimate. If you can afford to pay a larger down payment, you can reduce your total costs and how long it’ll take to pay off the loan.

Solar Panel Installation Company

The last significant cost factor you should consider is the installer you choose. Given the massive popularity of renewable energy solutions in San Francisco, you’ll have plenty of options to choose from, but each comes at different price points for labor and equipment.Companies that only sell products with high efficiency and therefore a higher price point — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come at a higher cost. It’s best to do some research and decide on the company that has the products, warranties and services you’re looking for and also fit into your budget.

How to Save on Solar Panels

Since the type of solar panels and the installer you choose considerably impacts your costs and your system’s durability and efficiency, it’s important to select the right ones for you. Here are some tips to keep in mind to help with your decision:

  • Installation Process: Get detailed information from your solar installer about the installation process and what to expect, including when the site survey will be completed and how long it will take.
  • Solar Panel Brands: Different companies will carry different brands and kinds of panels. If you prefer a specific brand, make sure the solar panel installer you’re considering has it.
  • Warranty: An all-inclusive, 25-year warranty can help keep your solar panels running for years to come and save you money on repairs and maintenance.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for clean energy professionals. If your solar panel installer is NABCEP-certified, it likely has a good reputation and is qualified to get the job done well. Another way you can research your installer’s reputation is by reading reviews.

EcoWatch's San Francisco, CA Solar Cost FAQs

What is the average cost of installing solar panels in San Francisco?

This is a tough question to answer precisely, because the cost depends on a variety of factors. Generally speaking, it costs about $17,350 for a 5-kW system and $34,700 for a 10-kW system after the ITC is applied. You can expect to pay more if you want additional solar equipment or more efficient panels, or if you have above-average energy needs. On the other hand, you can spend less if you go with a smaller solar panel system or less efficient solar panels.

Is it better to lease or buy solar panels in San Francisco?

Leasing solar panels can be an appealing choice, because it usually comes with low or $0 upfront payments. The downside is that you won’t be able to save as much. If you lease, you don’t own the system, so you can’t claim any tax rebates and credits and your home value won’t increase. Buying solar panels is a better way to go if you want to maximize your savings.

Does San Francisco have a net metering program?

The majority of states have net metering programs of some kind. Through these, you can either receive compensation for the extra power your system generates or or receive credits to put toward future energy bills. Currently there are just three states that don’t have any net metering laws: Alabama, Tennessee and South Dakota.

How long do solar panels last in San Francisco?

Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they should be disposed of at that time. What this means is how much energy they produce will have decreased significantly after that point. You can replace them once you've had them for that long or you can continue to use them at a lower efficiency.
