Factors that Affect Solar Panel Costs in Cupertino
There are a number of criteria that can affect your total installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar system.
Solar Equipment
The size of the solar system you need, which is measured in kilowatts, is the most important cost factor to consider. For every additional kilowatt you need, you can expect your total to increase by about $3,470. Some solar panel brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer better efficiency. In a city like Cupertino, where sunlight is abundant, efficiency can quickly pay off. Plus, if you have a small roof or limited space for your panels, higher efficiency options will be more impactful. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.
Solar Financing Terms
Solar panels can save you money on energy bills over many years, but they can also be a significant investment. That’s why many Cupertino homeowners opt to finance their solar panel systems to offset upfront costs.However, the interest on solar loans also increases your overall costs, so it’s vital to include that in your estimate as well. You can always reduce the total you pay in interest and sometimes even your APR by putting more money down.
Solar Panel Installation Company
A final consideration when trying to figure out the cost of solar for your home or business in Cupertino is the company you hire to install your solar panel system. As with choosing a company to renovate your kitchen, for example, there are plenty of solar installers that provide a range of services for different budgets.You may notice national solar installers that have lower prices due to their bigger brand name and access to bulk prices, or you might see small, local installation companies offering deals or specials to compete with those major players.

How to Save on Solar Panels
The company that does your system installation will affect the warranties and brands you have access to, and it will also have an impact on your total cost. Because selecting a company can be difficult, we have some tips to help you, such as:
- Reputation: Make sure your solar system installer 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.

EcoWatch's Cupertino, CA Solar Cost FAQs
How much does it cost to install solar panels in Cupertino?
This is a hard question to answer precisely, because the cost depends on a variety of factors. Broadly speaking, it costs about $17,350 for a 5-kW system and $34,700 for a 10-kW system after the ITC is applied. It will be more expensive if you want additional solar equipment or more efficient panels, or if you have above-average energy consumption. Conversely, you can spend less if you go with a smaller solar panel system or less efficient solar panels.
What other factors should I consider in addition to cost when buying solar panels?
The initial cost is a very important factor to consider, but whether it’s the most important for you depends on your reasons for going solar. In cities where rooftop space is limited, efficiency can be more important than the cost. Other factors that are important to be mindful of are the quality and durability of your solar panels.
Can solar panels eliminate my energy bills?
Solar panels can potentially eliminate your electricity bills depending on where you’re located and the efficiency of your system. Even if it doesn’t get rid of them completely, you can save a lot of money on your bills, about $1,610.35 per year.
How often do you have to replace solar panels?
Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they should be disposed of at that time. What this means is their energy production will have decreased significantly after that point. You can opt to replace them after having them for that long or you can continue to use them at a lower efficiency.
