One of the most common hindrances to achieving maximum efficiency from solar panels in Australia is the issue of shading. Shade can occur due to the trees and buildings around the property and can obstruct sunlight to fall directly upon the panels. This reduces the output efficiency of even the best solar panels in Australia.
Since the last several years, many dominant solar panel companies in Australia have switched to manufacturing half-cut solar panels from the earlier commonly manufactured full-size square cell panels.
The square cells are now cut in half and connected together in two different upper and lower groups on the same panel. This cell design enhances panel efficiency as the cells in both groups function at a common voltage but half the current. The lower current creates a lower working temperature for the cells and prevents hot spots or any other cell damage due to heat.
Shade causes minimal power losses in half-cut panels which results in higher panel efficiency. Let us see how:
How half-cut cells work in shade
Half-cut cells work in split-cell solar modules to improve performance and productivity when panels are partly shaded. When one part of the solar panels in Australia is shaded, the functioning and productivity of the other half are undisturbed. This is achieved by placing the half-cut cells in two groups on the same panel, in a parallel design, functioning much like two separate panels. The voltage is at par in both cell groups and the current is lowered by fifty percent creating maximum panel efficiency when partially shaded.
Half-cut solar panels in Australia are more efficient than other panel technologies. They have double the number of cells at 120 to 144 than monocrystalline panels. They are based on the industry-leading PERC technology which provides high panel productivity.
Merits of half-cut solar panels
1) Power loss caused due to shade is minimal in these panels.
2) Half-cut panels work efficiently with low irradiation.
3) The half-cut technology gives panels high shade tolerance by allowing the unshaded part of the panel to continue generating power even when the other part cannot perform optimally as shaded.
4) Due to the cell design the half-cut panels are more compact which prevents the occurrence of cracks.
5) Due to the low current functioning, the operating temperature becomes lower which diminishes the chances of hot spots in the panels.
6) Current flows easily as the half-cut design provides low electrical resistance.
7) Half-cut panels are highly reliable and durable.
8) These latest solar design panels are made with superior quality and robust materials.
Demerits of Half-Cut Solar Panels
1) The initial cost is higher than other types of panels.
2) Half-cut panels may require some soldering.
3) Internal cellular dysfunction due to cutting might be a possibility.
Half-cut solar panels, like other solar panels, must be maintained well to ensure the smooth functioning of your Australia solar. They can be cleaned using brushes, sponges, and even your garden hose to get rid of dirt and other debris. Regular inspection of components and efficiency must be done to detect any malfunction and its cause. The right care taken to repair or replace the damaged parts at the earliest will enhance the longevity and success of your solar system.
Half-cut solar panels significantly improve the energy output when shading is an issue. This unconventional solar technology yields greater productivity for a longer time period, affecting higher savings from your solar.
