Factors that Affect Solar Panel Costs in Lake Mathews

Cost is typically one of the most important factors for homeowners who are considering investing in solar. There are a few primary factors that will push your cost above or below the average in Lake Mathews: solar equipment and system size, financing options and the solar installation company you choose. We’ll go over each of these briefly below.

Solar Equipment

The cost of solar panel systems varies by thousands of dollars due to some different factors. One of the most significant factors is the system size, which is measured in kilowatts (kW). Solar power systems with better efficiency or power generation require better technology and/or more equipment, both of which can increase costs. For each additional kilowatt you need, your cost can go up by about $3,470.The brand and type of equipment you want for your solar system can raise or lower the price quite significantly. If you prefer a brand name like Tesla or SunPower, these are often more expensive than other brands. Efficiency also matters. Whether you’re opting for high efficiency because you have a small roof 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 extra equipment like an electric vehicle charger or solar batteries, this will also raise the cost.

Solar Financing Terms

Many homeowners find the average cost of solar in Lake Mathews to be too steep, even if the investment pays off over time. Thankfully, almost every solar installer in the area offers financing options. Solar loans greatly decrease upfront costs in most cases, but they also result in paying more over time because of interest.While solar loans make going solar more accessible for Lake Mathews homeowners, they can also add to the total you pay for your system, depending on your interest rate. If you make a larger down payment, though, you can avoid paying as much in interest.

Solar Panel Installation Company

A final consideration when trying to evaluate the cost of solar for your home or business in Lake Mathews is the company you get to install your PV system. As with choosing a company to build a deck or pool, for example, you’ll have many options for solar installers that offer a range of services at different price points.Companies that only sell high-efficiency and high-priced products — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come with an above-average cost. It’s best to do some research and choose a company that provides the products, warranties and services you’re looking for and also fits within your budget.

How to Save on Solar Panels

There are many companies available in Lake Mathews, and some homeowners feel overwhelmed considering their options. Choosing the right company for you can be challenging, so here are some tips to help you decide:

  • Contract: When reading over your solar installer’s contract, ask questions about any terms you’re not sure of and be sure you understand what happens in scenarios like a system part breaking or if the company goes out of business.
  • Installation Process: When going solar, it’s essential to maintain an open line of communication with your solar company. See to it that you understand how the installation process will go and the project timeline.
  • Solar Panel Brands: Different companies have different brands and kinds of panels. If you prefer a specific brand, make sure the solar installer you’re considering has it.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for renewable energy professionals. If your solar panel installer is NABCEP-certified, it most likely has a solid reputation and is qualified to install your solar system. Another way you can verify your installer’s reputation is by reading reviews.

EcoWatch's Lake Mathews, CA Solar Cost FAQs

How much does it cost to install solar panels in Lake Mathews?

The average cost of solar panels in Lake Mathews is about $17,350 for a 5-kW system and $34,700 for a 10-kW system before the ITC, but the actual 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.

Is it better to lease or buy solar panels in Lake Mathews?

Leasing solar panels can be an attractive choice, as it typically 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 option if you want to get the most savings.

Do solar panels increase your home value?

Buying or financing solar panels for your home can increase the value of your property by about 4%, according to research done by Zillow. The average home value in Lake Mathews is currently $577,757, which means you could be looking at a value of about $23,688 more than houses without a solar system. The exact figures will vary, but most experts agree that installing solar panels in Lake Mathews is a rewarding investment.

How often do you have to replace solar panels?

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