Factors that Affect Solar Panel Costs in Atherton

For many Atherton homeowners, the decision to install solar panels comes down to cost. However, the range of solar installation costs can be quite wide in Atherton, with typical prices between $20,000 to $40,000. There are several factors that significantly influence the price you'll pay, which we'll go over below.

Solar Equipment

When it comes to estimating the cost of a solar energy system in Atherton, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are primarily based on your home's energy consumption, which you can figure out by looking at past energy bills. Your total cost can increase by around $2,730 for each additional kilowatt you need. The brand and kind of equipment you choose for your solar system can increase or decrease the price quite significantly. If you prefer a brand name like Tesla or SunPower, these often come at a higher price than other brands. Efficiency also matters. Whether you're opting for high efficiency because you have a small roof or just want maximum energy production, you will be looking at a higher equipment cost, but this can typically lead to greater savings over time. Also, if you want additional equipment like an electric vehicle charger or solar batteries, this will also increase the cost.

Solar Financing Terms

If paying for solar panels out of pocket is difficult, solar loans are a popular option because they decrease your upfront costs and allow you to pay for your system over a term of, on average, between five and seven years. You'll have to consider the long-term cost of loans, including the total 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 getting a solar loan with a low interest rate could reduce your costs significantly.

Solar Panel Installation Company

A final consideration when trying to evaluate the cost of solar for your home or business in Atherton is the company you get to install your PV system. As with choosing a company to build a deck or pool, for example, there are plenty of solar installers that provide a range of services at different costs. Larger national companies usually have lower costs, but some local companies undercut them by promoting sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or add-on services like electric vehicle charger installation, they might be cheaper overall.

How to Save on Solar Panels

The solar panel company you go with will be a major factor in determining not only your total 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, such as:

  • Solar Panel Brands: The kind of solar panel you'd like to install plays a role in which installer you should opt for, since different companies have different panels.
  • Contract: Even though reading through a contract can take a lot of time, it's important to do it carefully so you can be sure you understand how much the equipment and services will cost and how part repairs and replacements will be handled.
  • Warranty: An all-inclusive, 25-year warranty can help keep your solar system running for a long time and save you money on part replacement and repairs.
  • 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 check your installer's reputation is by reading reviews.

Do solar panels increase your property value?

Solar panels can increase the value of your property by about 4%, according to research done by Zillow.

The exact figures will vary, but most experts agree that installing solar panels in Atherton is a worthwhile investment.

How long do solar panels last in Atherton?

Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable at that time. What this means is how much energy they produce will have decreased significantly after that point. You can decide to replace them after having them for that long or you can keep using them at a lower efficiency.
