Factors that Affect Solar Panel Costs in Discovery Bay

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

Solar Equipment

When it comes to estimating the price of solar panels in Discovery Bay, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are mainly based on your home's energy usage, which you can determine by looking at past power bills. Your overall cost can increase by about $2,730 for each additional kilowatt you need. The type of solar equipment you choose can increase or decrease your cost by thousands or even tens of thousands of dollars. If you opt for the most efficient solar panel brands, you'll end up paying more upfront than if you opted for the most affordable panels. However, higher efficiency could save you more over time on your energy bills. Additionally, extra products, like solar batteries, can bump up your total well above the Discovery Bay average.

Solar Financing Terms

Solar panels can save you money on utility bills over time, but they can also be a significant investment. That's why many Discovery Bay homeowners choose to finance their solar panel systems to make paying for solar more affordable. Though solar loans make adopting solar energy more accessible for Discovery Bay homeowners, they can also add to the total you pay for your system due to interest. If you make a larger down payment, though, you can avoid paying as much in interest.

Solar Panel Installation Company

A final factor to consider when trying to figure out the cost of solar for your home or business in Discovery Bay is the company you hire to install your PV system. Similar to 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. Larger national companies usually have lower costs, but some local companies keep up with them by promoting sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or add-on services like electric car charger installation, they might be cheaper overall.

How to Save on Solar Panels

The company that does your solar system installation will affect the warranties and brands you have access to, 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:

  • Solar Panel Brands: Different companies will offer different brands and types of panels. If you prefer a specific brand, make sure the solar company you're considering has it.
  • Contract: When reading over your solar company's contract, ask for clarification about any terms you're not sure of and make sure you understand what happens in scenarios such as a system component breaking or if the company goes out of business.
  • Installation Process: Homeowners should understand how exactly the installation process will be carried out, as well as important factors like the project timeline.
  • Reputation: Your solar installer should have a good reputation as a company and have demonstrated expertise in the field. Two ways to check this are to look for whether a company has technicians that hold a certification from the North American Board of Certified Energy Practitioners (NABCEP) and if it has satisfied reviews from previous customers.

EcoWatch's Discovery Bay, CA Solar Cost FAQs

How much does it cost to install solar panels in Discovery Bay?

The average cost of solar panels in Discovery Bay is about $13,650 for a 5-kW system and $27,300 for a 10-kW system before the ITC, but the actual cost will depend on things like the type of solar panels you want, what size system you need and how much energy you use.

Should I lease or buy solar panels in Discovery Bay?

Leasing solar panels can be an option if you can't afford to pay upfront or get a solar loan, but since you don't own the system, you don't have access to many solar incentives. Also your home value won't increase, so you'll have less savings over time. If you can afford to buy a solar system upfront, then buying is the better option if you want the most savings from going solar.

How will solar panels impact my property 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 Discovery Bay is currently $588,501, so you can expect a value of about $24,129 more than houses without a solar system. The exact figures will vary, but most experts agree that installing solar panels in Discovery Bay is a rewarding investment.

How long do solar panels last in Discovery Bay?

Even though 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 how much energy they produce will have decreased significantly after that point. You can decide to replace them after having them for that long or you can keep using them at a lower efficiency.
