Factors that Affect Solar Panel Costs in Atherton
There are a number of factors that can determine your solar panel installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that does the installation.
Solar Equipment
The size of the solar panel system you need to offset your energy usage, 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 nearly $2,730. The type of solar panels and equipment you choose is another factor that will significantly impact costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to be more expensive. Furthermore, solar equipment goes beyond just the solar panels themselves. You'll also need to think about 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
If paying for a solar system out of pocket is too expensive, solar loans are a solid option because they decrease your upfront costs and let you pay for your system over a term of, on average, between five and seven years. It's a good idea 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 off the loan.
Solar Panel Installation Company
The solar panel installer you pick will affect your total cost to go solar. Different companies will charge different amounts for the equipment and labor. Companies that only sell products with high efficiency and therefore a higher price point — 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 go with the company that has the products, warranties and services you're looking for and also fit into your budget.

How to Save on Solar Panels
The solar installer you choose will influence not only your overall costs, but also the types of solar panel brands, warranties, and other equipment you can get. When choosing a solar company, there are some important things you should consider, such as:
- Warranty: If you care about the endurance of your solar energy system, ensuring your company offers a 25-year, all-inclusive warranty can give you some peace of mind.
- Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a respected certification organization for sustainable energy professionals. If your solar panel installer is NABCEP-certified, it most likely has a solid reputation and is qualified to get the job done well. Another way you can verify your installer's reputation is by reading reviews.
- Solar Panel Brands: Not all solar companies offer the same brands of solar panels, so the brand and type of panel you want can play a big role in the company you opt for.
- Contract: When reading over your solar installer's contract, ask for clarification about any terms you're not sure of and be sure you understand what happens in scenarios such as a system part breaking or if the company goes out of business.

EcoWatch's Atherton, CA Solar Cost FAQs
How much does it cost to install solar panels in Atherton?
This is a difficult question to answer exactly, because the cost depends on a variety of factors. Broadly speaking, it costs about $13,650 for a 5-kW system and $27,300 for a 10-kW system after the ITC is applied. You can expect to pay more if you want other solar equipment or higher quality panels, or if you have higher-than-average energy usage. Conversely, you can spend less if you choose a smaller solar panel system or cheaper solar panels.
What other factors should I consider aside from 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 why you decided to go solar. In areas where rooftop space is limited, efficiency can trump the cost. Other factors that are important to keep in mind are the quality and durability of your solar panels.
Does Atherton have a net metering program?
Most states have net metering programs of some kind. Through these, you can get paid for the extra power your system generates or or receive credits to put toward future electricity bills. Currently there are just three states that don't have any net metering laws: Alabama, Tennessee and South Dakota.
How often do you have to replace solar panels?
On average, the lifespan of solar panels is about 25 to 30 years. Some even last up to 50 years, but their efficiency goes down by about 0.8% each year. You can choose to replace them sooner if you want to maintain a larger amount of energy production.
