Factors that Affect Solar Panel Costs in Castaic

Cost is usually one of the most important factors for homeowners who want to invest in solar. There are a few major factors that determine your overall cost in Castaic: solar equipment and system size, financing options and the solar installation company you choose. We'll cover each of these briefly below.

Solar Equipment

One of the most important factors to consider when it comes to the cost of going solar is the size of the solar system, which is measured in kilowatts (kW). The more power your household uses, the larger your system will likely need to be. You can expect to spend about $2,730 per kilowatt in Castaic. The brand of solar panels and equipment you choose is another factor that will largely affect costs. Solar panels that are more efficient, like monocrystalline panels, tend to cost more. Plus, solar equipment consists of more than just the solar panels themselves. You'll also need to consider the kind of racks used to mount the panels, inverters, solar batteries, etc. It's important to take all of this into consideration when looking for a solar system that falls within your budget.

Solar Financing Terms

For some homeowners, paying for a solar system out of pocket can be difficult. Solar loans are available from most installers in Castaic, which can lower, or in some cases totally eliminate, your upfront costs to make solar more accessible. However, the interest on solar loans also adds to your all-in costs, so it's important to consider that as well. You can always lower the total you pay in interest and possibly even your APR by putting more money down.

Solar Panel Installation Company

The solar installation company you pick will influence your total cost to make the switch to solar energy. Different companies will charge different amounts for the equipment and labor. Additionally, some companies in Castaic know more about local solar incentives and can help you make good use of additional rebates or tax exemptions. However, they may charge more for that service. Even if they cost more upfront, they could end up saving you more money in the long run.

How to Save on Solar Panels

The company that does your system installation will affect the warranties and brands available to you, and it will also have an impact on your total cost. Since picking a company can be a tough decision, we have some tips to help you, such as:

  • Installation Process: Get detailed information from your solar installer about the installation process and what to expect, such as when the site survey will be completed and how long it will take.
  • Solar Panel Brands: Different companies have various brands and types of panels. If you prefer a specific brand, make sure the solar panel company you're considering has it.
  • Warranty: If you're worried about the endurance of your solar panel system, verifying that your installer offers a 25-year, all-inclusive warranty can help put you at ease.
  • Contract: Even though reading through a contract can be tedious, it's important to do it fully so you can make sure you understand what services your solar company will provide and the terms of the warranty.

EcoWatch's Castaic, CA Solar Cost FAQs

How much does it cost to install solar panels in Castaic?

This is a hard question to answer exactly, because the cost depends on a few different factors. Generally speaking, it costs about $13,650 for a 5-kW system and $27,300 for a 10-kW system after the ITC is applied. You can expect to pay more if you want additional 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 less expensive solar panels.

Are solar panels free in Castaic?

A solar panel system isn't free in Castaic, but there are some options that can make getting them more feasible, such as leasing solar panels or getting a solar loan. There may also be local programs or incentives that can help lower the cost.

Does Castaic have a net metering program?

Each state has some kind of net metering programs except Tennessee, South Dakota and Alabama currently. Some states let you sell power back to the grid, but others just give you credit toward your future utility bills.

How often do you have to replace solar panels?

Although the average lifespan of solar panels is 25 to 30 years, that doesn't mean they should be disposed of at that time. What this means is the amount of energy they produce will have decreased significantly after that point. You can replace them once you've had them for that long or you can continue to use them at a lower efficiency.
