Factors that Affect Solar Panel Costs in San Diego
The cost of installing a solar system in San Diego can vary by more than $10,000 from home to home. Your actual cost depends on several factors. The most significant one is your system size, and other factors include equipment choices, financing options and the solar installer you choose.
Solar Equipment
The cost of solar panels varies by thousands of dollars due to a few different factors. One of the most significant factors is the system size, which is measured in kilowatts (kW). Solar power systems that have higher efficiency or power production need better technology and/or more equipment, both of which can increase costs. For each additional kilowatt you need, your cost can go up by about $2,730. There are a lot of different solar panel brands and the one you choose also changes the cost. In many cases, the brands that are more efficient tend to also cost more. Additionally, the type of equipment you choose can affect your total cost. If you only need panels, your system will be much less expensive than if you also need solar batteries or an electric vehicle charger.
Solar Financing Terms
Most solar companies in San Diego provide solar loans, which reduce the initial cost of installing solar. Even though solar loans make adopting solar energy more accessible for San Diego homeowners, they can also raise the total you pay for your system, depending on your interest rate. If you make a larger down payment, though, you can cut back on how much interest you have to pay.
Solar Panel Installation Company
The last major cost factor you should keep in mind is the installer you choose. Given the massive popularity of renewable energy solutions in San Diego, you'll have plenty of options to choose from, but each comes at various price points for labor and equipment. Companies that only sell high-efficiency and high-priced products — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come with an above-average cost. It's best to do some research and go with the company that has the products, warranties and services you want and also is within your budget.

How to Save on Solar Panels
Since the kind of solar panels and the installation company you choose significantly influences your costs and your system's efficiency, production, and durability, it's important to pick the right ones for you. Here are some things to keep in mind to help with your decision:
- Solar Panel Brands: Not all solar installers offer the same brands of solar panels, so the brand and type of panel you want can play a large role in the company you go with.
- Installation Process: Get details from your solar company about the installation process and what to expect, such as when the site survey will be done and how long it will take.
- Reputation: Your solar installer should have a good reputation as a company and have verifiable expertise in the field. Two ways to check this are to look for whether a company has technicians that hold a certification from the North American Board of Certified Energy Practitioners (NABCEP) and if it has positive reviews from past customers.
- Contract: Though reading through a contract can be tedious, it's important to do it thoroughly so you can be sure you understand how much the equipment and services will cost and the terms of the warranty.

EcoWatch's San Diego, CA Solar Cost FAQs
What is the average cost of installing solar panels in San Diego?
This is a tough question to answer precisely, because the cost depends on many factors. Generally speaking, it costs about $13,650 for a 5-kW system and $27,300 for a 10-kW system after the ITC is applied. It will cost more if you want other solar equipment or higher quality panels, or if you have above-average energy consumption. On the other hand, you can spend less if you opt for a smaller solar panel system or less expensive solar panels.
Should I lease or buy solar panels in San Diego?
Leasing solar panels can be an appealing choice, because it often comes with low or $0 upfront payments. The drawback 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 incentives and your home value won't increase. Buying solar panels is a better option if you want to get the most savings.
Can you sell solar power back to the grid in San Diego?
The majority of states have net metering programs of some kind. Through these, you can receive compensation for the extra power your system generates or or receive credits to put toward future electricity 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 Diego?
Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely at that time. What this means is the amount of energy they produce will have decreased significantly after that point. You can replace them after having them for that long or you can keep using them at a lower efficiency.
