PV solar panels are like puzzles made of tiny solar cells, enclosed in glass. These cells are made of silicon, a bit like computer chips. They have a positive part and a negative part that work together to make electricity, kind of like a battery. SunPower solar panels also have special adhesives and coatings to protect these cells and keep them working well even in different weather conditions.

With solar, as with many things, “you get what you pay for.” Not all solar systems are alike. The quality of the technology matters in the long run. The durability, reliability and efficiency of solar panels can vary widely by manufacturer. If you settle for Conventional Panels that might cost less out-of-pocket, you can expect to see average (or below average) results and less savings over time.

A higher quality panel like SunPower Maxeon might cost a little more up front, but you will see more predictable performance in the long run. SunPower Maxeon panels generate more energy, last longer, are backed by a stronger warranty, and are produced more sustainably than Conventional Panels. This means SunPower Maxeon panels will offset more of your electricity bill, saving you more, and do so with the peace of mind you expect from a top-quality product.

You can power your entire house using solar energy. By installing solar panels, you can generate electricity from sunlight and run your home's appliances, lighting, and other electrical systems. An inverter converts the solar-generated electricity into a usable form, and batteries can store excess energy for use during cloudy days or at night. Factors like your energy consumption, the size of the solar system, available sunlight, and location are all important. Our professional installers will help you determine the right setup for your needs.

There are several financing options for solar installations, including solar loans, solar leases, and Power Purchase Agreements (PPAs).

The amount you can save on energy bills depends on your energy consumption, the number of solar panels you have, and local electricity rates. On average, homeowners can save anywhere from 20% to 70% on their electricity bills with solar panels.

A typical home needs between 17 and 21 solar panels to cover 100 percent of its electricity usage. The number of panels you'll need to install depends on your geographic location, panel efficiency, panel-rated power, and personal energy consumption habits. While the answer isn't always simple, we've put together some example cases to help you understand how many solar panels you might need to install an effective home solar system.
