Factors that Affect Solar Panel Costs in San Carlos
For many San Carlos homeowners, the decision to adopt solar energy comes down to cost. However, the range of solar installation costs can be quite wide in San Carlos, with typical prices between $20,000 to $40,000. There are various factors that greatly influence the price you’ll pay, which we'll go over below.
Solar Equipment
The cost of solar panel systems varies by thousands of dollars due to a variety of factors. One of the main factors is the system size, which is measured in kilowatts (kW). Solar power systems that have higher efficiency or power generation require 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.There are several different solar panel brands and the one you pick also affects the cost. Generally speaking, the brands that are more efficient tend to also cost more. In addition, the type of equipment you want to install can affect your total cost. If you just need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.
Solar Financing Terms
If paying for a solar system in cash is difficult, solar loans are a popular route because they reduce your upfront costs and let you pay for your system over a term of, on average, between five and seven years.You’ll have to consider the long-term cost of loans, including the total interest you’ll pay over the length of the loan. If you can only get a high-interest loan, then your total can be hundreds or even thousands of dollars above the equipment and labor cost. Making a larger down payment or getting a solar loan with a low APR could reduce your costs significantly.
Solar Panel Installation Company
The solar company you pick will affect your total cost to go solar. Different companies will charge different amounts for the equipment and labor.The company’s size can sometimes play the most significant role in the cost of installation. Larger national companies, like SunPro and Sunrun, often have lower pricing because of greater resources and better pricing. Smaller local companies might be more costly, but they generally have better customer service and more customization options, and the occasional sale or discount can bring their pricing lower to compete with bigger names.

How to Save on Solar Panels
Since the model of solar panels and the company you choose considerably influences your costs and your system’s efficiency, production, and durability, it’s important to pick the right ones for you. Here are some tips to keep in mind to help with your decision:
- Solar Panel Brands: Homeowners will have different preferences for panels based on their locations 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 access to the exact one you may want or need, so make sure you peruse their list of offerings before making your decision.
- Reputation: Your solar installer should have a solid 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.
- Warranty: Companies typically offer different types of warranties that cover different things. A 25-year, all-inclusive warranty is the gold standard.
- Contract: When reading through your solar company’s contract, ask questions about any terms you’re not sure of and be sure you understand what happens in scenarios such as a system component breaking or if the company goes out of business.
