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 is determined by several factors. The most significant one is your system size, and other factors include the equipment you choose, financing options and the solar company you choose.
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 power your household consumes, the larger your system will likely need to be. You can expect to pay around $2,730 per kilowatt in San Diego. The brand and type of equipment you get for your solar system can increase or decrease 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 can expect a higher equipment cost, but this can typically lead to more savings over time. Plus, if you want additional equipment like an electric vehicle charger or solar batteries, this will also raise the cost.
Solar Financing Terms
Most solar installers in San Diego provide solar loans, which reduce your upfront costs of installing a solar system. However, the interest on solar loans also adds to your all-in costs, so it's crucial to include that in your estimate as well. You can always reduce the total you pay in interest and sometimes even your APR by making a larger down payment.
Solar Panel Installation Company
Lastly, the company you opt for to install your solar panels can impact how much you pay. San Diego's solar companies all have different labor costs and add varying upcharges to equipment. The company's size sometimes plays the most significant role in the cost of installation. Larger national companies, like SunPro and Sunrun, often have lower pricing because they have access to more resources and bulk pricing. Smaller local companies might be more costly, but they can sometimes have better customer service and more customization options, and the occasional sale or discount can bring their pricing lower to compete with bigger companies.

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.
