Factors that Affect Solar Panel Costs in Duarte

Cost is often one of the most important factors for homeowners considering investing in solar. There are a few key factors that will push your cost above or below the average in Duarte: 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 a few different factors. One of the notable factors is the system size, which is measured in kilowatts (kW). Solar power systems with higher efficiency or power production need 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.Some solar panel brands — like Maxeon from SunPower — cost more upfront but also tend to offer higher efficiency. In a city like Duarte, where sunlight is abundant, efficiency can quickly pay off. Also, if you have a small roof or you don’t have a lot of space for your panels, higher efficiency options will be a better option. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

Solar panels can save you money on utility bills over many years, but they can also be a big investment. That’s why many Duarte homeowners opt to finance their solar panel systems to make going solar more affordable.It’s a good idea to include the interest you’ll pay in your final cost estimate. If you can afford to pay a larger down payment, you can reduce your total costs and how long it’ll take to pay back the loan.

Solar Panel Installation Company

Lastly, the company you choose to install your solar system can play a part in determining how much you pay. Duarte’s solar companies all have different labor costs and add varying upcharges to equipment. Larger national companies generally have lower costs, but some local companies undercut them by offering sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or extra 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 company you choose significantly impacts your costs and your system’s durability and efficiency, it’s important to pick the right ones for you. Here are some tips to keep in mind to help with your decision:

  • 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 done and what the project timeline is.
  • Warranty: If you’re concerned about the endurance of your solar panels, making sure your company offers a 25-year, all-inclusive warranty can help put you at ease.
  • Solar Panel Brands: Different companies will offer various brands and models of panels. If you want a specific brand, make sure the solar panel company you’re considering has it.
  • Contract: It’s important to read your solar installer’s contract well to understand what services they will provide, what the warranty covers and what you can expect about the cost.
