If you opt for the most efficient solar panel brands, you’ll end up paying more upfront than if you opted for the most affordable panels. However, more efficient panels could save you more in the long run on your power bills. Additionally, add-on products, such as solar batteries, can bring your total well above the Petaluma average.

EcoWatch's Petaluma, CA Solar Cost FAQs
How much does it cost to install solar panels in Petaluma?
This is a hard question to answer precisely, because the cost depends on a few different factors. Broadly 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 extra 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 choose a smaller solar panel system or less efficient solar panels.
Is cost the most important consideration when buying solar panels?
The upfront 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 cities where rooftop space is limited, efficiency can trump the cost. Other factors that are important to consider are the quality and durability of your solar panels.
Does Petaluma have a net metering program?
Most states have net metering programs of some kind. Through these, you can either get paid for the extra power your system produces or or receive credits to put toward future energy bills. Currently there are just three states that don’t have any net metering laws: Alabama, Tennessee and South Dakota.
How many solar panels should I get to power my home?
To figure out how many solar panels you need, you should find out how much energy your home uses and how much sunlight your home gets. For a general estimate, however, since each panel can typically produce about 250 to 400 watt-hours per hour, the average home will need 20 to 35 panels.
