Whether "black on black" solar panels are "better" depends on various factors and perspectives, and there is no definitive answer.
For some homeowners, the all-black design of solar panels can be more visually appealing, blending in better with darker roofs and other architectural elements. This can be a plus for those who prioritize aesthetics when installing solar panels.
The color of solar panels, specifically whether they are black or another color, does not directly affect their energy conversion efficiency. Solar panel efficiency is determined by factors such as the type of photovoltaic (PV) cells used, the quality of the materials, and the panel's design. Therefore, black on black solar panels are not inherently more efficient than other colored panels.
Black surfaces tend to absorb more heat than lighter colors. However, modern solar panels are designed with materials and coatings that help manage heat and prevent overheating, regardless of their color. While black panels may absorb more heat initially, this does not necessarily translate to lower performance or efficiency over time.
The durability of solar panels is not significantly impacted by their color. Instead, it's more closely related to the quality of the materials used, the panel's construction, and the manufacturer's warranty.
From an environmental perspective, the color of solar panels has little to no impact. What matters more is the clean energy they produce and the reduction in greenhouse gas emissions they enable.
