Factors that Affect Solar Panel Costs in South Pasadena
The cost of installing a solar system in South Pasadena can vary by more than $10,000 from home to home. Your actual cost is dependent on several factors. The largest one is the size of the system your household needs, and other factors include the equipment you choose, financing options and the solar company you choose.
Solar Equipment
The size of the solar system you need for your home, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, you can expect your total to increase by about $3,470. The brand and kind of equipment you want for your solar system can increase or decrease the price quite significantly. If you prefer a trusted brand name like Tesla or SunPower, these often have a higher price tag than other brands. Efficiency also matters. Whether you’re opting for high efficiency because you have limited roof space or just want maximum energy production, you can expect a higher equipment cost, but this can typically lead to more savings over time. Plus, if you want add-ons like an electric vehicle charger or solar batteries, this will also raise the cost.
Solar Financing Terms
Most solar installers in South Pasadena offer solar loans, which reduce your upfront costs 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 more than the original cost. Making a larger down payment or getting a solar loan with a low APR could reduce your costs significantly.
Solar Panel Installation Company
A final consideration when trying to estimate the cost of solar for your home or business in South Pasadena is the company you hire to install your PV system. As with choosing a company to renovate your kitchen, for example, there are plenty of solar installers that offer a range of services at different price points.The company’s size can sometimes play the most considerable role in your total costs. Larger national companies, like SunPro and Sunrun, often have lower pricing due to access to more resources and better pricing. Smaller local companies might be more costly, but they generally have better customer service and more customization options, and the occasional sale or discount can bring their pricing down to compete with bigger names.

How to Save on Solar Panels
Since the kind of solar panels and the installation company you choose has an impact on your costs and your system’s durability and efficiency, it’s important to select the right ones for you. Here are some things to keep in mind to help with your decision:
- Contract: Look through the contract terms closely to make sure you understand how much it will cost, project timeline incentives and warranties.
- Warranty: An all-inclusive, long-term warranty can help keep your solar panel system running for a long time and save you money on repairs and maintenance.
- Reputation: Well-established companies likely have a high reputation. This is important because it ensures that it will not only see your solar installation through, but will also provide quality aftercare and customer service, such as part repairs and replacements.
- Installation Process: Make sure you’re on the same page with the installer with regard to how the installation process will go and what you need to do before your solar panels are installed, such as updating or replacing your electrical system or roof.
EcoWatch's South Pasadena, CA Solar Cost FAQs
How much does it cost to install solar panels in South Pasadena?
This is a tough question to answer precisely, because the cost depends on many factors. Generally speaking, it costs about $17,350 for a 5-kW system and $34,700 for a 10-kW system after the ITC is applied. You can expect to pay more if you want extra solar equipment or higher quality panels, or if you have above-average energy usage. On the flip side, you can spend less if you opt for a smaller solar panel system or cheaper solar panels.
Should I lease or buy solar panels in South Pasadena?
Leasing solar panels can be an appealing choice, as it often comes with low or $0 upfront payments. The drawback is that you won’t be able to save as much. If you lease, you don’t own the system, so you can’t claim any tax rebates and credits and your home value won’t increase. Buying solar panels is a better way to go if you want to maximize your savings.
Can you sell solar power back to the grid in South Pasadena?
Most states have net metering programs of some kind. Through these, you can either receive compensation 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.
What solar power system size is right for my home?
To figure out what solar panel system size you need, you should find out how much energy your home requires and how much sunlight your home gets. For a general estimate, however, since each panel can usually produce about 250 to 400 watt-hours per hour, the average house will need 20 to 35 panels.
