This guide explores both options, helping you make an informed decision that aligns with your energy needs, budget, and aesthetic preferences.

What Are Solar Shingles and Solar Panels?

Solar shingles and solar panels both capture sunlight and convert it into electricity, yet they differ in appearance and application. Solar shingles are integrated into your roof, functioning as both a roofing material and an energy source. Made to resemble traditional roofing, they offer a sleek, modern look while generating solar power.

In contrast, traditional solar panels are mounted on racks above the roof. These panels are larger and more visible but are widely recognized for their high efficiency and lower installation costs. For many homeowners, the choice between solar shingles and solar panels boils down to factors such as aesthetics, installation complexity, and energy output.

Solar Shingles: Integrated into the roof, blending with the structure.
Solar Panels: Mounted on racks, visible but highly efficient.
Main Difference: Solar shingles act as both a roof and an energy generator, while solar panels are added to the roof as separate units.

How Each Technology Works

The Technology Behind Solar Shingles

Solar shingles operate on photovoltaic (PV) technology similar to that used in traditional solar panels. Each shingle contains small PV cells, which capture sunlight and convert it into electricity. Unlike conventional solar panels, however, solar shingles are designed to look and function like standard roofing shingles, blending seamlessly with the roof’s structure.

Photovoltaic Cell Integration: The PV cells in solar shingles are embedded directly within the roofing material. This integration allows solar shingles to capture sunlight directly on the roof’s surface, without additional mounting or support structures.
Electricity Generation: Once sunlight hits the PV cells, the energy is converted into direct current (DC) electricity. This DC electricity is then routed through an inverter, which converts it into alternating current (AC) suitable for powering household appliances and other home energy needs.
Seamless Roofing Functionality: Solar shingles replace the existing roof material, serving a dual purpose as both an energy-generating source and a roofing material. Because they are installed in place of standard shingles, they must be installed with precision to ensure the roof remains watertight and durable.

Solar shingles are a great choice for homeowners who want a clean, integrated appearance. However, because they require full roof integration, they are generally best suited for homes undergoing a complete roof replacement.

The Technology Behind Solar Panels

Solar panels, like solar shingles, rely on PV cells to capture sunlight and convert it into electricity. However, the structure and setup of solar panels differ significantly, making them a more flexible option for a wider variety of roof types.

Photovoltaic Cell Structure: Solar panels are composed of a series of PV cells arranged in a larger grid. These cells are typically mounted within a metal frame and protected by a glass covering. This structure allows them to capture and convert sunlight efficiently while being shielded from the elements.
Racking System for Installation: Solar panels are installed on racks or mounting systems placed above the roof. This design keeps them elevated, which allows air circulation beneath the panels, helping to maintain performance and longevity even in warmer climates.
Energy Conversion and Routing: As with solar shingles, the energy generated by solar panels is initially in DC form and requires an inverter to convert it to AC power. Solar panel systems often include a centralized or micro-inverter to manage this conversion process.

This elevated design of solar panels makes them easier to install, maintain, and replace if necessary, as they do not require structural changes to the roof.

Efficiency and Energy Output

When comparing the energy efficiency of solar shingles vs. solar panels, traditional solar panels generally provide a higher energy output per square foot. This increased efficiency is due to the flexibility in positioning, which allows panels to be installed at optimal angles to capture the maximum amount of sunlight.

Solar Panels: The adaptability of solar panels enables them to be positioned at angles that maximize sunlight exposure. As a result, they tend to have a higher energy output, which makes them ideal for homes with greater energy needs.
Solar Shingles: Because solar shingles are part of the roof itself, they are limited by the existing roof pitch and orientation, which can affect how much sunlight they capture. While modern solar shingles are quite efficient, they generally produce slightly less energy per square foot than panels, particularly if the roof orientation isn’t ideal.

Installation Complexity

The installation of solar shingles involves more extensive work than that of solar panels due to their integrated design. Solar shingles must be installed in place of traditional roofing materials, which requires the removal of existing shingles and careful alignment of the solar units to ensure both weatherproofing and energy functionality.

Solar Shingles Installation: The shingles need to be laid out and positioned precisely, as they replace parts of the existing roof. This requires more time and often means higher labor costs, particularly if a roof replacement is necessary.
Solar Panels Installation: The process for installing solar panels is typically faster and simpler. Panels are mounted on racks, which are secured to the roof without needing to remove existing roofing material. This makes installation faster, and panels can often be repositioned or adjusted more easily.
