Factors that Affect Solar Panel Costs in San Martin
While the average cost of a solar system in San Martin is $7,249, your final cost may be above or below the average. There are quite a few factors that can have a sizable impact on the cost of a solar system installation. Below are some of the more crucial things to keep in mind.
Solar Equipment
The size of the solar energy system you need, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, your total will most likely increase by nearly $3,470. The brand and type of equipment you choose for your solar system can increase or decrease the price quite significantly. If you prefer a brand name like Tesla or SunPower, these often have a higher price tag 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
Solar panels can save you money on utility bills over many years, but they can also be a big investment. That’s why many San Martin homeowners decide to finance their solar panel systems to make going solar more affordable.However, the interest on solar loans also adds to your overall costs, so it’s important to include that in your estimate as well. You can always bring down the total you pay in interest and in some cases even your APR by putting more money down.
Solar Panel Installation Company
Lastly, the company you hire to install your solar system can affect your pricing. San Martin’s solar companies all have different labor costs and add varying upcharges to equipment. Some companies only sell high-quality, high-efficiency and high-price products — 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 go with the company that offers the products, warranties and services you want and also fits within your budget.

How to Save on Solar Panels
The solar panel company you choose will be a major factor in determining not only your overall costs, but also the types of solar panel brands, warranties, and other equipment you can get. When choosing a solar company, there are several important things you should consider, such as:
- Reputation: Make sure your solar company has a good reputation by confirming it has certifications and licenses, checking how long it's been in business and reading reviews by previous customers and solar experts like the EcoWatch team.
- Installation Process: Make sure you’re on the same page with the installer regarding how the installation process will go and what needs to be done before your solar system is installed, such as repairing your electrical system or roof.
- Solar Panel Brands: Homeowners will have different preferences for panels depending on their roof configurations and how much efficiency they need. Although there are many options for which kind of solar panel you can get, not every company will have the exact one you may want or need, so be sure to peruse their list of options before making your decision.
- Warranty: Companies typically offer different kinds of warranties that cover different things. A 25-year, all-inclusive warranty is the gold standard.
