Three Tree Roofing Infographic: How Solar Works

How Solar Panels Work

Solar energy is derived from converting the sun's radiation into electricity through photovoltaic cells or thermal collectors. Each PV cell is made of silicon, which is a semiconductor material that can convert light into electricity. When sunlight hits a PV cell, it excites the electrons in the silicon atoms, causing them to flow and generate an electric current. This direct current (DC) is then sent to an inverter, which converts it into alternating current (AC) that can be used to power your home.

The use of these technologies enables us to generate power without generating any emissions. In addition to being clean, inexpensive, and reliable, solar-powered systems are also low maintenance and highly efficient. This makes them an attractive option for homeowners who want to reduce their reliance on traditional sources of energy like oil and gas.

Types of Solar Panels

Image showing different types of solar panels

There are several types of solar panels available in the market. Below are the most common types of solar panels.

Monocrystalline Solar Panels icon

Monocrystalline Solar Panels are made from a single, high-purity silicon crystal, which makes them highly efficient and space-efficient. They are usually more expensive than other types of solar panels but have a longer lifespan and higher energy output.

Polycrystalline Solar Panels icon

Polycrystalline Solar Panels are made from multiple silicon crystals, which makes them slightly less efficient than monocrystalline solar panels. They are also less expensive and can be a good option for homeowners on a budget.

Bifacial Solar Panels icon

Thin-Film Solar Panels are made from a thin layer of photovoltaic material, which makes them lightweight and flexible. They are less efficient than monocrystalline or polycrystalline solar panels but can be a good option for certain applications, such as portable solar systems.

Bifacial Solar Panels icon

Bifacial Solar Panels have a transparent backside, which allows them to capture sunlight from both sides of the panel, increasing their energy output. They are typically more expensive than monocrystalline or polycrystalline solar panels.

ROOFER PRO TIP: Monocrystalline Solar Panels are most commonly installed on residential homes.

What are My Options for Solar Energy Systems?

We have discussed factors to consider when assessing your home's suitability for solar. Now we are moving on to discuss the various types of solar systems available. Grid-tied Solar Systems are the most common type of solar system. They are connected to the utility grid, allowing excess energy produced by the panels to be sold back to the grid, and ensuring a steady supply of electricity when the solar panels are not producing energy.

Off-grid Solar Systems

Off-grid Solar Systems are not connected to the utility grid and are designed to provide all of the electricity needs for a home or property. These systems require a battery bank to store excess energy produced during the day for use at night or during periods of low solar production.

Hybrid Solar Systems

Hybrid Solar Systems are a combination of grid-tied and off-grid solar systems. They allow for energy storage in batteries and can switch between drawing energy from the grid and the battery bank depending on the needs of the home.

Building-Integrated Photovoltaics (BIPV) Systems

Building-Integrated Photovoltaics (BIPV) Systems integrate solar panels directly into the design of a building's roof or walls. This type of system can replace traditional building materials and provide a clean and aesthetically pleasing energy source.

Concentrated Solar Power (CSP) Systems

Concentrated Solar Power (CSP) Systems use mirrors or lenses to concentrate sunlight onto a small area, which heats a fluid to generate steam and produce electricity. This technology is typically used in large-scale utility installations and not generally used for residential solar systems.

Portable Solar Systems

Portable Solar Systems are designed to be easily transported and set up for use in remote areas or for outdoor activities like camping or RV trips and not generally used for residential solar systems.

Community Solar Systems

Community Solar Systems are shared solar installations that allow multiple people to benefit from a single solar array. This type of system is especially useful for those who do not have suitable roofs for solar installations or cannot afford a solar installation on their own.

Solar Panel Manufacturers

There are varying opinions on who is the best solar panel manufacturer. SolarReviews released there 2023 Best Solar Panel Manufacturers list.
