Types of Solar Panels and Their Efficiency
In the realm of solar panels, there are chiefly three types that homeowners and businesses tend to consider: monocrystalline, polycrystalline, and thin-film.
Monocrystalline panels, recognized by their uniform dark look and rounded edges, boast the highest efficiency rates because they are made from the highest-grade silicon. Typically, their efficiency ranges from 15% to 20%. They perform exceptionally well in warm weather, which makes them a solid choice for Norfolk's moderate climate, where summers can get warm but not excessively hot.
Polycrystalline panels, with their signature blue hue and square shape, have a slightly lower efficiency, usually between 13% and 16%. They are made by melting multiple silicon crystals together and are more cost-effective. However, they tend to have a higher temperature coefficient compared to monocrystalline panels, meaning their performance could dip a bit during hot summer days in Norfolk.
Thin-film panels stand out due to their lightweight and flexible design, making them versatile for many surfaces. They vary in material and efficiency, with some reaching about 11%. Their efficiency decreases the fastest in high temperatures and intense sunlight, which may not make them the first choice for Norfolk's sunny summer. However, their lower cost and adaptability can justify their use in specific applications, particularly where panel weight is a concern.
For Norfolk, Virginia, monocrystalline seems to be the preferred choice considering the balance of efficiency, performance in warmer temperatures, and long-term reliability. They might be more of an investment upfront, but their durability and efficiency may offer better savings over time, especially with Virginia's solar rebates and incentives.
