Factors that Affect Solar Panel Costs in Sunnyvale
The cost of installing a solar system in Sunnyvale can vary by more than $10,000 from home to home. Your actual cost depends on several factors. The biggest one is your system size, and other factors include the equipment you choose, financing options and the solar company you choose.
Solar Equipment
When it comes to estimating the price of a solar energy system in Sunnyvale, one of the most important factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are largely based on your home’s energy usage, which you can figure out by looking at past power bills. Your overall cost can increase by around $3,470 for each additional kilowatt you need.The type of solar panels and equipment you get is another factor that will considerably impact costs. Solar panels that are more efficient, like monocrystalline panels, tend to cost more. Furthermore, solar equipment goes beyond just the solar panels themselves. You’ll also need to decide on the kind of racks used to mount the panels, inverters, solar batteries, etc. It’s important to take all of this into consideration when searching for a solar system that’s in your budget.
Solar Financing Terms
Solar panels can save you money on power bills over time, but they can also be a significant investment. That’s why many Sunnyvale homeowners choose to finance their solar panel systems to make paying for solar more affordable.However, the interest on solar loans also increases your total costs, so it’s crucial to include that in your estimate as well. You can always reduce 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 key cost factor you should keep in mind is the installer you choose. Given the massive popularity of sustainable energy solutions in Sunnyvale, you’ll have lots of options to choose from, but each comes at various price points for labor and equipment.The company’s size can sometimes play the most significant role in your total costs. Larger national companies, like SunPro and Sunrun, often have lower pricing because they have access to more resources and bulk pricing. Smaller local companies might be more costly, but they can sometimes have better customer service and more customization options, and the occasional sale or promotion can bring their pricing down to compete with bigger names.

How to Save on Solar Panels
There are a lot of solar installers to choose from, all of which offer different warranties, solar panel brands and price points. To help you pick the right company for you, here are some tips to keep in mind:
- Warranty: A comprehensive, long-term warranty can help keep your solar system running for a long time and save you money on part replacement and repairs.
- Reputation: Companies that have been in business for many years likely have a high reputation. This is important because it ensures that it will not only see your solar installation through, but will also provide adequate aftercare and customer support, such as part repairs and replacements.
- 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 like a system part breaking or the company going out of business.
- Installation Process: Make sure you’re aligned with the installer with regard to how the installation process will go and what needs to be done before your solar panels are installed, such as updating your electrical system or roof.
