Factors that Affect Solar Panel Costs in South San Francisco

While the average cost of a solar system in South San Francisco is $5,867, your final cost may differ. There are quite a few factors that can have a significant impact on the cost of a solar panel installation. Below are some of the more crucial things to keep in mind.

Solar Equipment

The cost of solar panels varies by thousands of dollars due to a few different factors. One of the main factors is the system size, which is measured in kilowatts (kW). Solar power systems with better efficiency or power production use 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 $2,730. The kind 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. On the other hand, more efficient panels could save you more in the long run on your power bills. Additionally, add-on products, like solar batteries, can bump up your total well above the South San Francisco average.

Solar Financing Terms

Many homeowners find the average cost of solar in South San Francisco to be prohibitively costly, even if the investment pays off over time. Fortunately, almost every solar installer in the area offers financing options. Solar loans substantially decrease upfront costs in most cases, but they also lead to paying more over time due to interest. It's wise to add the interest you'll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and how long it'll take to pay off the loan.

Solar Panel Installation Company

A final factor to consider when trying to figure out the cost of solar for your home or business in South San Francisco is the company you hire to install your solar system. Similar to choosing a company to install new cabinets, for instance, you'll have no shortage of solar installers that offer a range of services for different budgets. Larger national companies usually have lower costs, but some local companies keep up with them by offering sales and discounts. While the smaller companies might not have access to 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 kind of solar panels and the company you choose has an impact on your costs and your system's durability and efficiency, it's important to pick the right ones for you. Here are some things to keep in mind to help with your decision:

  • Warranty: A quality company rises above other companies by offering the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
  • Solar Panel Brands: The brand of solar panel you'd like plays a role in which company you should choose, since different companies provide different panels.
  • Reputation: Make sure your solar panel installer has a good reputation by confirming it has certifications and licenses, checking how long it's been in business and reading reviews by previous customers and solar experts like EcoWatch.
  • Contract: Although reading through a contract can be tedious, it's important to do it fully so you can make sure you understand how much the equipment and services will cost and how part repairs and replacements will be handled.
