Factors that Affect Solar Panel Costs in San Jose

Cost is often one of the most important factors for homeowners who want to invest in solar. There are a few key factors that affect your total cost in San Jose: solar equipment and system size, financing options and the solar installation company you choose. We'll discuss each of these briefly below.

Solar Equipment

The size of the solar system you need for your household, 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 about $2,730. The solar equipment you choose can increase or decrease your cost by thousands or even tens of thousands of dollars. If you opt for the most efficient solar panel brands, you'll end up paying more upfront than if you opted for the most affordable panels. However, higher efficiency could save you more over time on your electric bills. In addition, extra products, such as solar batteries, can bump up your total well above the San Jose average.

Solar Financing Terms

For some homeowners, paying for a solar system out of pocket can be financially overwhelming. Solar loans are provided by most installers in San Jose, which can bring down, or in some cases completely eliminate, your upfront costs to make solar more accessible. You'll have to consider the long-term cost of loans, including the amount of interest you'll pay over the length of the loan. If you're only able to 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 finding a solar loan with a low APR could reduce your costs considerably.

Solar Panel Installation Company

Finally, the company you opt for to install your solar system can play a part in determining how much it costs. San Jose's solar companies all have different labor costs and add varying upcharges to equipment. You may come across national solar installers that have lower prices because of their bigger brand name and access to bulk equipment prices, or you might see small, local installation companies offering deals or promotions to compete with those larger companies.

How to Save on Solar Panels

The solar installer you go with will affect not only your overall costs, but also the kinds of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are several important things you should consider, such as:

  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for renewable energy professionals. If your solar panel installer is NABCEP-certified, it most likely has a good reputation and is qualified to install your solar system. Another way you can verify your installer's reputation is by reading reviews.
  • Solar Panel Brands: Different companies have different brands and kinds of panels. If you know you want a specific brand, make sure the solar installer you're considering has it.
  • Contract: Although reading through a contract can be tedious, it's important to do it thoroughly so you can make sure you understand how much the equipment and services will cost and the terms of the warranty.
  • Warranty: Each company may offer different types of warranties that cover different things. A 25-year, all-inclusive warranty is the gold standard.

EcoWatch's San Jose, CA Solar Cost FAQs

How much does it cost to install solar panels in San Jose?

The average cost of solar panels in San Jose is about $13,650 for a 5-kW system and $27,300 for a 10-kW system before the ITC, but the actual cost will depend on things like the type of solar panels you want, what size system you need and how much energy you consume.

Is cost the most important consideration when buying solar panels?

Cost is definitely one of the most important things to keep in mind when buying solar panels, but other important factors include efficiency, durability, and quality.

Is going solar worth it?

Solar panels can be a fruitful investment for most homeowners, but they might not be worth it for everyone. If your home doesn't get enough sunlight and/or your energy bills are already reasonably low, solar panels might not be for you.

What solar power system size is right for my home?

To figure out how many solar panels you need, you need to know how much energy your home requires and how much sunlight your home gets. For a general estimate, however, since each panel can typically produce about 250 to 400 watt-hours per hour, the average home will need 20 to 35 panels.
