Factors that Affect Solar Panel Costs in Walnut
For many Walnut homeowners, the decision to install solar panels comes down to cost. However, the range of solar installation costs can be quite wide in Walnut, with typical prices between $20,000 to $40,000. There are numerous factors that significantly influence the price you’ll pay, which we'll go over below.
Solar Equipment
When it comes to estimating the price of solar panels in Walnut, one of the most important factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are largely based on your home’s energy consumption, which you can gauge by looking at past energy bills. Your total cost can increase by about $3,470 for each additional kilowatt you need.The solar equipment you choose can increase or decrease your cost by thousands or even tens of thousands of dollars. If you get the most efficient solar panel brands, you’ll end up paying more upfront than if you opted for the most affordable panels. However, higher efficiency could save you more in the long run on your electric bills. In addition, add-on products, like solar batteries, can bring your total well above the Walnut average.
Solar Financing Terms
Most solar installers in Walnut provide solar loans, which reduce the initial cost of installing solar.You’ll have to consider the long-term cost of financing options, including the amount of interest you’ll pay over the length of the loan. If you can only 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 remarkably.
Solar Panel Installation Company
A final consideration when trying to figure out the cost of solar for your home or business in Walnut is the company you hire to install your solar panel system. As with choosing a company to install new cabinets, for example, you’ll have many options for solar installers that provide a range of services at different costs.Larger national companies typically have lower costs, but some local companies undercut them by promoting sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or additional services like electric car charger installation, they might be cheaper overall.

How to Save on Solar Panels
Since the model of solar panels and the installer you choose has an impact on your costs and your system’s efficiency, production, and durability, it’s important to select the right ones for you. Here are some tips to keep in mind to help with your decision:
- Installation Process: When making the switch to solar energy, it’s important to keep an open line of communication with your solar company. Make sure you understand how the installation process will go and the completion timeline.
- Contract: Look through the contract terms carefully to make sure you understand how much it will cost, project timeline incentives and warranties.
- Warranty: Many companies offer different kinds of warranties that provide different kinds of coverage. A 25-year, all-inclusive warranty is the gold standard.
- Solar Panel Brands: Not all solar installers carry the same brands of solar panels, so the brand and type of panel you want can play a significant role in the company you opt for.

EcoWatch's Walnut, CA Solar Cost FAQs
How much does it cost to install solar panels in Walnut?
The average cost of solar panels in Walnut is about $17,350 for a 5-kW system and $34,700 for a 10-kW system before the ITC, but the real cost will depend on certain factors such as the type of solar panels you want, what size system you need and how much energy you consume.
Are solar panels free in Walnut?
You can’t get solar panels for free in Walnut. However, you may still be able to install them on a lower budget. You can lease solar panels for a low upfront cost or, if you want to own your solar panels, you can finance them with a solar loan.
Can you sell solar power back to the grid in Walnut?
The majority of 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 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 how much energy they produce will have decreased significantly after that point. You can choose to replace them once you've had them for that long or you can continue to use them at a lower efficiency.
