Factors that Affect Solar Panel Costs in King City
There are several factors that can determine your solar panel installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that performs the installation.
Solar Equipment
The cost of solar panels varies by thousands of dollars due to some different factors. One of the main factors is the system size, which is measured in kilowatts (kW). Solar power systems that have greater efficiency or power production 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.The brand and type of equipment you get 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 can expect a higher equipment cost, but this can typically lead to greater savings over time. Also, if you want extra equipment like an electric vehicle charger or solar batteries, this will also increase the cost.
Solar Financing Terms
For some homeowners, paying for solar panels out of pocket can be difficult. Solar loans are offered by most installers in King City, which can reduce, or in some cases eliminate, your upfront costs to make solar more affordable.It’s wise to factor the interest you’ll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and the amount of time it’ll take to pay back the loan.
Solar Panel Installation Company
The solar installation company you pick will play a role in your total cost to make the switch to solar power. Different companies will charge different amounts for the equipment and labor.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 cost more. It’s best to do some research and find a company that offers the products, warranties and services you want and also fits within your budget.

How to Save on Solar Panels
The company that does your system installation will affect the warranties and brands available to you, and it will also have an impact on your total cost. Since choosing a company can be a tough decision, we have some tips to help you, such as:
- Warranty: Companies typically offer different kinds of warranties that provide different kinds of coverage. A 25-year, all-inclusive warranty is the gold standard.
- Solar Panel Brands: The kind of solar panel you want to get plays a role in which installer you should opt for, since different companies provide different panels.
- Installation Process: When making the switch to solar, it’s necessary to keep an open line of communication with your solar panel company. See to it that you understand how the installation process will go and the project timeline.
- Reputation: Your solar installer should have a sound reputation as a company and have proven expertise in the field. A couple of 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 good reviews from past customers.
