Factors that Affect Solar Panel Costs in Redwood City

Although the average cost of a solar system in Redwood City is $5,867, your actual cost may differ. There are quite a few factors that can have a major impact on the cost of a residential solar panel installation. Below are some of the more important things to take into consideration.

Solar Equipment

The size of the solar panel system you need for your home, which is measured in kilowatts, is the most important cost factor to consider. For every additional kilowatt you need, your total will most likely increase by around $2,730. The kind of solar panels and equipment you want is another factor that will largely affect costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to cost more. Further, solar equipment consists of more than 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 falls within your budget.

Solar Financing Terms

Solar panels can save you money on energy bills over many years, but they can also be a big investment. That's why many Redwood City homeowners opt to finance their solar panel systems to offset upfront costs. It's a good idea 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 how long it'll take to pay off the loan.

Solar Panel Installation Company

A final factor to keep in mind when trying to evaluate the cost of solar for your home or business in Redwood City is the company you hire to install your solar 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. Companies that only sell high-quality, high-efficiency and high-price products — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come at a higher cost. It's best to do some research and decide on the company that provides the products, warranties and services you want and also fit into your budget.

How to Save on Solar Panels

The solar company you go with will be a major factor in determining not only your overall costs, but also the kinds of solar panel brands, warranties, and other equipment you can get. When choosing a solar company, there are a few important things you should keep in mind, including:

  • Solar Panel Brands: Homeowners will have different preferences for panels based on their roof configurations and energy needs. Even though there are many options for which kind of solar panel you can get, not every company will have the exact one you may want or need, so make sure you peruse their list of options before making your decision.
  • Reputation: Your solar installer should have a good reputation as a company and have demonstrated expertise in the field. Two ways to check this are to look for whether a company has technicians certified by the North American Board of Certified Energy Practitioners (NABCEP) and if it has positive reviews from past customers.
  • Warranty: If you care about the endurance of your solar energy system, ensuring your installer offers a 25-year, all-inclusive warranty can help put you at ease.
  • Contract: When reading over 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 component breaking or the company going out of business.

EcoWatch's Redwood City, CA Solar Cost FAQs

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

The average cost of solar panels in Redwood City is about $13,650 for a 5-kW system and $27,300 for a 10-kW system before the ITC, but the real cost will depend on certain factors such as the kind of solar panels you want, what size system you need and how much energy you use.

Should I lease or buy solar panels in Redwood City?

Leasing solar panels can be an option if you are unable to pay upfront or secure a solar loan, but since you don't own the system, you don't have access to many solar incentives. Also your home value won't increase, so you'll have less savings over time. If you can afford to buy a solar system upfront, then buying is the better option if you want the most bang for your buck from going solar.

Can you sell solar power back to the grid in Redwood City?

The majority of states offer net metering programs of some kind. Through these, you can either get paid for the extra power your system generates or or receive credits to put toward future utility bills. Currently there are just three states that don't have any net metering laws: Alabama, Tennessee and South Dakota.

How long do solar panels last in Redwood City?

Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely at that time. What this means is how much energy they produce 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.
