Shade-Tolerant Solar Panels for Boats: Keeping the Lights On, Even When the Clouds Roll In
Solar panels have become increasingly popular on boats, offering a quiet and simple way to power onboard systems. However, traditional solar panels suffer from a significant drawback: their performance plummets in partially shaded conditions. This can be a major issue on a boat, where sails, booms, masts, and other onboard equipment can cast shadows on the panels.
Fortunately, advancements in solar technology have led to the development of shade-tolerant solar panels. These panels are designed to mitigate the effects of shading and maintain energy production even when partially shaded, unlike the vast majority of solar panels available which when even a small portion of the panel is shaded the panel output drops precipitously. Let's delve into the technical aspects that make the shade tolerant panels stand out:
1. Wiring of the panels:
Wiring the panels such that they are split in half, acting as two independent panels in one. A manufacturer can further divide those halves in half again with bypass diodes so it can effectively be four independent panels in one.
2. Bypass Diodes:
Traditional solar panels connect individual solar cells in series. When one cell is shaded, the entire series is affected, significantly reducing output. Shade-tolerant panels incorporate bypass diodes within the panel's circuitry. These diodes allow current to "bypass" the shaded strings of cells, minimizing the impact on the overall power output.
3. Maximum Power Point Tracking (MPPT) Charge Controllers:
MPPT charge controllers are essential for maximizing the efficiency of shade-tolerant solar panels. These sophisticated devices continuously monitor the panel's output and adjust the voltage to extract the maximum possible power, even under varying shade conditions.
4. Panel Design and Cell Configuration:
Some shade-tolerant panels utilize innovative cell configurations, such as half-cut cells or shingled cells. These designs reduce the impact of shading by dividing the panel into smaller, independent sections. If one section is shaded, the other sections continue to generate power independent of the shaded section.
5. Shade tolerant cells by Sunpower, and A+ grade as well:
Sunpower Maxeon cells are back contact which means the wires are across the rear of the cell and cannot be seen. This allows the solar cell itself to be shade tolerant. You can shade any portion of the cell and the cell will continue to produce power. This differs from the other solar cells on the market with front contact, where small amounts of shading can shut down one cell and thus the entire string of cells will go down, similar to Christmas lights.
6. Maximum efficiency solar cells:
Use A+ grade Sunpower solar cells (24.4% efficiency, the maximum commercially available on the market) to generate power even when the cell itself is partially shaded. This also maximizes power output over the course of a day, as better cells do better at low sun angles (and high sun angles), generating more watt hours over the course of a day than cheaper, lower quality, and non shade tolerant solar cells.
Benefits of Shade-Tolerant Solar Panels on boats:
-
Increased Energy Production: By mitigating the effects of shading, these panels generate more power throughout the day, especially in dynamic onboard environments. This maximizes watt hours generated per day.
-
Improved Reliability: Consistent power output ensures critical systems remain operational, even under fluctuating light conditions.
-
Greater Flexibility in Panel Placement: Sailors have more options for mounting panels, without being limited by potential shading issues.
