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 effiiency than typical square cell panels

Full silicone solar 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 silicone solar 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.

Independent Off-Grid Solar Power Source

One or more solar panels can be connected a battery bank and power inverter using a solar charge controller. You can therefore have a 240v power supply anywhere in the world without grid supply. Please see our solar power kits.

Solar Panels do still generate power during cloudy and rainy weather

A rough to guide solar panel power output relative to weather conditions:-

• 100% power output - clear sky midday sun with the panel fully tilted toward the sun's position in the sky.
• 75-85% output - clear sky midday sun but with the panel laid flat
• 50% output - thin cloud, or intermittent small clouds
• 10-20% output - midday overcast sky or rainy conditions

In the event that the solar panel is in shade for a prolonged period, our solar panels either have one or two built-in bypass diodes which will enable the panel to continue generating.
