Factors that Affect Solar Panel Costs in Altadena

There are many criteria that can determine your installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that does the installation.

Solar Equipment

The size of the solar panel system you need, which is measured in kilowatts, is the most important cost factor to consider. For every additional kilowatt you need, you can expect your total to increase by nearly $3,470. The brand and type of equipment you want 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 limited roof space or just want maximum energy production, you will be looking at a higher equipment cost, but this can typically lead to more savings over time. Also, if you want extra equipment like an electric vehicle charger or solar batteries, this will also raise the cost.

Solar Financing Terms

Most solar installers in Altadena offer solar loans, which reduce your upfront costs of installing a solar system.However, the interest on solar loans also adds to your all-in costs, so it’s crucial to keep that in mind as well. You can always reduce the total you pay in interest and possibly even your APR by making a larger down payment.

Solar Panel Installation Company

The remaining key cost factor you should consider is the installer you choose. Given the massive popularity of renewable energy solutions in Altadena, you’ll have a great number of options to choose from, but each comes at varying price points for labor and equipment.The company’s size can sometimes play the most significant role in the cost. Larger national companies, like SunPro and Sunrun, often have lower prices due to access to greater 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 promotion can bring their pricing down to compete with bigger companies.

How to Save on Solar Panels

Since the brand of solar panels and the installer you choose significantly influences your costs and your system’s efficiency, production, and durability, it’s important to pick the right ones for you. Here are some things to keep in mind to help with your decision:

  • Installation Process: When going solar, it’s necessary to keep an open line of communication with your solar panel installer. Make sure you understand how the installation process will go and the completion timeline.
  • Warranty: A quality company rises above other companies by providing the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
  • Contract: When reading through your solar company’s contract, ask questions about any terms you’re not sure of and make sure you understand what happens in scenarios like a system part breaking or if the company goes out of business.
  • Reputation: Solar installers that have great reviews from their customers and that have been in business for many years in most cases offer high-quality solar panel installation and expertise.

EcoWatch's Altadena, CA Solar Cost FAQs

What is the average cost of installing solar panels in Altadena?

This is a hard question to answer precisely, because the cost depends on a few different 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. It will be more expensive if you want extra solar equipment or more efficient panels, or if you have higher-than-average energy usage. Conversely, you can spend less if you choose a smaller solar panel system or less efficient solar panels.

Can you get solar panels for free in Altadena?

You can’t get solar panels for free in Altadena. However, you may still be able to get them on a lower budget. You can lease solar panels for a low upfront cost or, if you’d rather own your solar panels, you can finance them with a solar loan.

Can you sell solar power back to the grid in Altadena?

The majority of states offer net metering programs of some kind. Through these, you can receive compensation for the extra power your system generates or or receive credits to put toward future utility 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?

On average, solar panels can last about 25 to 30 years. Some even last up to 50 years, but their efficiency decreases by about 0.8% each year. You can choose to replace them sooner if you want to maintain a larger level of energy production.
