In choosing solar panels, understanding the differences in types and materials is important. Each option has unique features that suit different needs and budgets.
Monocrystalline vs. Polycrystalline
Monocrystalline solar panels are made from a single crystal structure. They are known for their high efficiency and long lifespan. These panels take up less space, making them a great choice for residential roofs.
Polycrystalline panels are made from multiple crystal structures. They tend to be less efficient than monocrystalline panels but are generally more affordable. We see many clients choose polycrystalline panels when they want to keep costs down.
When considering efficiency, monocrystalline panels often offer around 15-20% efficiency rates, while polycrystalline panels usually range from 13-16%. We recommend assessing your roof space and energy needs to choose the right type.
Thin-Film Solar Panels
Thin-film solar panels are lightweight and flexible. They are made by placing a thin layer of photovoltaic material on a backing surface. This allows them to be integrated into various surfaces.
These panels are less efficient than crystalline options, usually around 10-12%. However, they perform better in low-light conditions and high temperatures. Thin-film panels are often a good fit for commercial applications or structures with specific installation needs.
Installation is easier with thin-film panels because they are lighter. This can lead to lower installation costs and fewer structural concerns for roofs. We have found that they are a popular choice among our commercial clients.
Mounting and Racking Systems
Proper mounting and racking systems are essential for solar panel installation. They ensure that panels are secure and positioned correctly to capture sunlight.
Roof-mounted systems are the most common. They utilize brackets attached to the roof structure, providing a strong foundation. This system is suitable for most types of roofs.
Ground-mounted systems are another option. They are installed on the ground and can be adjusted for optimal sun exposure. This type is ideal for homes with ample yard space.
We use quality materials in our mounting systems to ensure durability. This minimizes the potential for damage from weather and adds to the panel's longevity.
