Factors that Affect Solar Panel Costs in Redwood City

Cost is typically one of the most important factors for homeowners who want to invest in solar. There are a few key factors that will push your cost above or below the average in Redwood City: solar equipment and system size, financing options and the solar installation company you choose. We’ll go over each of these briefly below.

Solar Equipment

When it comes to estimating the price of a solar energy system in Redwood City, one of the most important factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are mainly based on your home’s energy consumption, which you can figure out by looking at past energy bills. Your overall cost can increase by around $3,470 for each additional kilowatt you need.There are several different solar panel brands and the one you pick also affects the cost. In many cases, the brands that have better efficiency tend to also cost more. In addition, the type of equipment you’re looking to get can affect your total cost. If you only need panels, your system will be much less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

If paying for solar panels in cash is too expensive, solar loans are a solid option because they cut back your upfront costs and allow you to pay for your system over a term of, on average, between five and seven years.It’s wise to factor the interest you’ll pay in your final cost estimate. If you can afford to pay a larger down payment, 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 panel installation company you pick will affect your total cost to go solar. Different companies will charge different amounts for the equipment and labor.You may notice national solar installers that have lower prices because of their bigger brand name and access to bulk prices, or you might see small, local installation companies offering deals or promotions to compete with those major players.

How to Save on Solar Panels

Since the kind of solar panels and the installer you choose has an impact on your costs and your system’s efficiency, production, and durability, it’s important to pick the right ones for you. Here are some things to keep in mind to help with your decision:

  • Warranty: If you care about the longevity of your solar panel system, making sure your installer offers a 25-year, all-inclusive warranty can give you some peace of mind.
  • Contract: Review the contract terms closely to make sure you understand how much it will cost, project completion timeline rebates and warranties.
  • Reputation: Make sure your solar panel installer has a good reputation by confirming it has certifications and licenses, checking its number of years in business and reading reviews by past customers and solar experts like EcoWatch.
  • Installation Process: One of the most important things to understand when going solar is the installation process itself. Be sure to clarify any details you should know with your solar installer, such as what permits you should secure and what the project timeline is.

EcoWatch's Redwood City, CA Solar Cost FAQs

How much does it cost to install solar panels in Redwood City?

This is a hard question to answer precisely, because the cost depends on a few different factors. Generally 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 other solar equipment or more efficient panels, or if you have higher-than-average energy consumption. On the flip side, you can spend less if you opt for a smaller solar panel system or cheaper solar panels.

What other factors should I consider aside from cost when buying solar panels?

Cost is a crucial factor to consider, but whether it’s the most important for you depends on why you decided to go solar. In places where rooftop space is limited, efficiency can be more important than the cost. Other factors that are important to consider are the quality and durability of your solar panels.

Is making the switch to solar worth it?

Solar panels can be a good investment for a majority of homeowners, but they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight and/or your power bills are already pretty low, solar panels might not be for you.

How often do you have to replace solar panels?

On average, solar panels can last about 25 to 30 years. Some even last up to 50 years, but their efficiency decreases by about 0.8% each year. You can choose to replace them sooner if you want to maintain a higher amount of energy production.
