Factors that Affect Solar Panel Costs in Sonoma
For many Sonoma homeowners, the decision to install a solar energy system rests on cost. However, the range of solar installation costs can be quite wide in Sonoma, with typical prices between $20,000 to $40,000. There are various factors that greatly influence the price you’ll pay, which we'll go over below.
Solar Equipment
When it comes to estimating the price of a solar panel system in Sonoma, 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 usage, which you can figure out by looking at past energy bills. Your total cost can increase by about $3,470 for each additional kilowatt you need.There are several different solar panel brands and the one you choose also changes the cost. Generally, the brands that have better efficiency tend to also cost more. Additionally, the type of equipment you’re looking to get can affect your total cost. If you just need panels, your system will be much less expensive than if you also need solar batteries or an electric vehicle charger.
Solar Financing Terms
Most solar companies in Sonoma offer solar loans, which reduce your upfront costs of installing a solar system.It’s wise 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 back the loan.
Solar Panel Installation Company
A final consideration when trying to figure out the cost of solar for your home or business in Sonoma is the company you hire to install your PV system. As with choosing a company to build a deck or pool, for instance, you’ll have no shortage of solar installers that provide a range of services at different price points.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 additional services like electric vehicle charger installation, they might be cheaper overall.

EcoWatch's Sonoma, CA Solar Cost FAQs
How much does it cost to install solar panels in Sonoma?
The average cost of solar panels in Sonoma is about $17,350 for a 5-kW system and $34,700 for a 10-kW system before the ITC, but the actual cost will depend on certain factors such as the model of solar panels you want, what size system you need and how much energy you use.
Is cost the most important consideration 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 trump the cost. Other factors that are important to be mindful of are the quality and durability of your solar panels.
How much can I save on power bills after switching to solar?
It is possible to eradicate your electricity bills with solar panels, but for most homeowners in Sonoma, that will require at least a 10-kW system. Not all homes will have the roof space for that size system, so you’ll want to contact a local solar installer to see how many panels can fit on your roof.
How often do you have to replace solar panels?
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 their energy production will have decreased significantly after that point. You can replace them after having them for that long or you can keep using them at a lower efficiency.
