Factors that Affect Solar Panel Costs in San Diego

There are many factors that can play into 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

System size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of going solar. Because of that, it’s crucial to accurately ascertain the size of the solar energy system needed for your home by figuring out your energy needs.The brand and kind of equipment you choose for your solar system can increase or decrease 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 limited roof space 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 add-ons like an electric vehicle charger or solar batteries, this will also increase the cost.

Solar Financing Terms

For some homeowners, paying for solar panels out of pocket can be financially overwhelming. Solar loans are provided by most installers in San Diego, which can bring down, or in some cases totally eliminate, your upfront costs to make solar more accessible.However, the interest on solar loans also increases your total costs, so it’s crucial to keep that in mind as well. You can always lower the total you pay in interest and in some cases even your APR by putting more money down.

Solar Panel Installation Company

The solar company you go with to handle your switch to sustainable energy can have an effect on your total costs. There are about 3 solar panel companies in San Diego, and each can charge varying amounts for labor and equipment.Larger national companies usually have lower costs, but some local companies compete with them by promoting sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or additional services like electric car charger installation, they might be cheaper overall.

How to Save on Solar Panels

There are a large number of companies available in San Diego, and some homeowners feel overwhelmed considering their options. Picking the right company for you can be tough, so here are some tips to help you decide:

  • 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 likely has a solid reputation and is qualified to install your solar system. Another way you can research your installer’s reputation is by reading reviews.
  • Solar Panel Brands: Not all solar installers offer the same brands of solar panels, so the brand and type of panel you want can play a considerable role in the company you choose.
  • Warranty: Warranties that provide coverage for defective panels and repairs over a long period of time such as 25 years are the gold standard in the business, and offering such a warranty is one sign of a good company.
  • Contract: Even though reading through a contract can take a lot of time, it’s important to do it thoroughly so you can be sure you understand what services your solar company will provide and how part repairs and replacements will be handled.

EcoWatch's San Diego, TX Solar Cost FAQs

What is the average cost of installing solar panels in San Diego?

The average cost of solar panels in San Diego is about $16,650 for a 5-kW system and $33,300 for a 10-kW system before the ITC, but the real cost will depend on stuff such as the model of solar panels you want, what size system you need and how much energy you consume.

Should I lease or buy solar panels in San Diego?

Leasing solar panels can be an option if you can’t afford to pay upfront or secure a solar loan, but since you don’t own the system, you don’t have access to many solar incentives. Also your property 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.

Is it worth going solar in San Diego?

Whether or not solar panels are worth it depends on a variety of factors like the cost of electricity near you and the amount of direct sunlight your roof gets.

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 amount of energy production.
