Solar Equipment

If you choose 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 energy bills. Additionally, add-on products, like solar batteries, can bump up your total well above the San Diego average.
Solar Financing Terms
Solar panels can save you money on energy bills over time, but they can also be a significant investment. That’s why many San Diego homeowners choose to finance their solar panel systems to offset upfront costs.It’s wise to factor the interest you’ll pay in your final cost estimate. If you can afford to pay a higher down payment, you can reduce your total costs and how long it’ll take to pay back the loan.

There are about 3 solar panel companies operating in San Diego, and each can charge varying amounts for labor and equipment.You may see national solar installers that have lower prices due to their bigger brand name and access to bulk pricing, or you might see small, local installation companies offering deals or promotions to compete with those major players.

How to Save on Solar Panels
The solar installer you go with will impact not only your overall costs, but also the kinds of solar panel brands, warranties, and other equipment you can get. When choosing a solar company, there are a few important things you should consider, including:
- Installation Process: When making the switch to solar, it’s important to maintain an open line of communication with your solar company. Confirm that you understand how the installation process will go and the project completion timeline.
- Reputation: Your solar installer should have a sound reputation as a company and have proven expertise in the field. A couple of 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 good reviews from past customers.
- Contract: Look through the contract terms thoroughly to make sure you understand how much it will cost, completion timeline rebates and warranties.
- 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.
