Factors that Affect Solar Panel Costs in San Marcos
The cost of installing a solar system in San Marcos can vary by more than $10,000 from home to home. Your actual cost depends on several factors. The largest one is the size of the system your home needs, and other factors include equipment choices, financing options and the solar installer you choose.
Solar Equipment
The cost of solar panel systems varies by thousands of dollars due to some different factors. One of the notable factors is the system size, which is measured in kilowatts (kW). Solar power systems that have better efficiency or power production need better technology and/or more equipment, both of which can raise costs. For each additional kilowatt you need, your cost can go up by about $3,470.The brand and kind of equipment you want 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 limited roof space or just want maximum energy production, you will be looking at a higher equipment cost, but this can typically lead to more savings over time. Plus, if you want add-ons like an electric vehicle charger or solar batteries, this will also raise the cost.
Solar Financing Terms
Many homeowners find the average cost of solar in San Marcos to be prohibitively costly, even if the investment pays off over time. Thankfully, nearly every solar installer in the area offers financing options. Solar loans remarkably decrease upfront costs in most cases, but they also lead to higher prices over time because of interest.However, the interest on solar loans also adds to your all-in costs, so it’s important to keep that in mind as well. You can always lower the total you pay in interest and in some cases even your APR by making a larger down payment.
Solar Panel Installation Company
The last major cost factor you should consider is the installer you choose. Given the massive popularity of sustainable energy solutions in San Marcos, 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 want and also fit into your budget.

How to Save on Solar Panels
The solar panel company you choose will influence not only your total 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 keep in mind, such as:
- Warranty: A high-quality company rises above other companies by offering the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
- Contract: Before signing a contract with a solar installer, make sure you read it through carefully so you understand the terms. Also, ask questions if you’re unsure about some of the terms, such as what to do if a component breaks or malfunctions and if there are any guarantees about energy production.
- Solar Panel Brands: The brand of solar panel you need plays a role in which installer you should opt for, since different companies offer different panels.
- Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a respected certification organization for clean energy professionals. If your solar panel installer is NABCEP-certified, it likely has a solid reputation and is qualified to install your solar system. Another way you can verify your installer’s reputation is by reading reviews.

EcoWatch's San Marcos, CA Solar Cost FAQs
How much does it cost to install solar panels in San Marcos?
This is a hard question to answer exactly, 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 extra solar equipment or higher quality panels, or if you have above-average energy usage. On the other hand, you can spend less if you choose a smaller solar panel system or less efficient solar panels.
Is it better to lease or buy solar panels in San Marcos?
Leasing solar panels can be an appealing choice, as it commonly 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 incentives and your home value won’t increase. Buying solar panels is a better option if you want to maximize your savings.
How will solar panels impact the value of my home?
Solar panels can increase the value of your home significantly as long as you buy or finance your panels and don’t choose a solar lease or power purchase agreement (PPA). According to research done by Zillow, the average home value increases by about 4.1% after installing a solar system."
What solar power system size is right for my home?
The exact number of solar panels you need depends on your household energy needs and how much sunlight your roof gets. You can take a look at your energy bills for the past year to get an idea of the solar system size you'll need. The average household has to get between 20 and 35 panels to account for their typical energy usage.
