Half cut solar cells

• Solar Panels with half-cut solar cells and 9 to 12 buzz bars connecting the cells are 8-10% Smaller than typical square cell panels
• Solar Panels with half-cut solar cells and 9 to 12 buzz bars connecting the cells are 3% higher efficiency than typical square cell panels

Full siliconesolar cells used to be square, sometimes with the corners cut off, but now the mainstream trend with all the big solar manufacturers is for half cut, small rectangular silicone cells, due to their higher efficiency.

Solar panel technology has moved on considerably in the last few years with the introduction of half cut solar cells which can provide 2 to 3% more efficiency and higher watts per square metre. This means that the same power solar panels used in the past can now be 8-10% smaller. Alternatively you can have bigger solar panels with higher power output, but don't take up as much space.

This works by doubling the number of solar cells and increasing the number of ribbons, (BB's / buzz bars) which connect the siliconesolar cells together within the panel. This helps to lower resistance in the panel, which in turn reduces tiny voltage drops in the many panel connections. Overall this provides more power output. The smaller cells are also less likely to have microfracture issues and with improved cloudy day performance.

MPPT Smart 100/30

Smart Solar MPPT 100/30A is one of the leading MPPT solar charge controllers on the market. The controller gathers power from your solar panels and safely charges your batteries. MPPT: Ultra Fast Maximum Power Point Tracking ensures that every drop of available power is rinsed out of your panels, and harvested for storage. The advantage of this is most noticeable when the sky is partially clouded, and light intensity is constantly changing. Built-in bluetooth by pairing with your smartphone allows you to monitor performance, change settings and update firmware. The intelligent load output function prevents damage by not allowing batteries to run ‘flat'. MPPT controller will improve energy harvest by up to 30% compared to PWM charge controllers and by up to 10% compared to slower MPPT controllers.
