What are Half Cell Modules?
Traditional full cell panels ( 60 cells) are made with 60 or 72 cells on the entire panel. A half-Cell module doubles the number of cells into 120, 144 or 166 cells per panel. The panel is the same size as a full cell panel but with double the cells. By doubling the number of cells this technology creates more avenues to catch energy from sunlight to send into the inverter.
Essentially, Half-Cell technology is the process of cutting cells into half, reducing resistance so efficiency can increase. Traditional full cell panels with 60 or 72 cells produce resistance which can lower the panel's ability to produce more power. Whereas Half-Cells with 120, 144 or 166 cells have lower resistance which means more energy is being captured and produced. Half-Cell panels have smaller cells on each panel which reduces mechanical stresses on the panel. The smaller the cell the lesser chance of the panel micro cracking.
Moreover, Half-Cell technology provides higher power output ratings and are usually more reliable than traditional full cell panels.

Why turn to Half-Cell technology for your next install?
The opportunity to generate more power for your customers and to save them money is at the forefront of any rooftop PV system sale. Half-Cell technology can take your solar installs to the next level.
The increase in Half-cell popularity over the years is due to some very distinct advantages such as:
- Excellent performance in low light situations
Half-cell technology is excellent in low light situations. This is due to the design the increased number of cells feeds more power to the inverter.
- Half-cell technology is more durable for long-life performance
HC technology is less susceptible to micro-cracking due to the smaller size of the solar cells. The mechanical stress on the entire panel is lessened which reduces the opportunity for micro cracks to develop. Therefore, HC panels are more durable and less prone to cracking over long periods of time.
- Performs better in high-heat conditions
Half-Cell technology is proven to perform well under high heat conditions. As we know Africa never falls short of hot weather conditions. This is the reason why Half-Cell technology is increasing in popularity in the African solar market. Half-Cell technology is less susceptible to panel malfunctions.
Hot spots are very common in poorly manufactured solar PV panels and can severely reduce the lifespan of a solar PV panel. Half-Cell solar PV panels have less heat below the individual cells on the panel. Hot spots are common and a negative that comes with solar PV systems that receive high levels of constant heat. In some major cases, hot spots can cause fire risks to the customer's home. Having a split junction box reduces cell heating and the possibility for hot spots occur.
