Solar & Emergency Power: Solar panels

Description

There are three main types of Solar Panels with details and differences outlined below, Shingled panels have the highest efficiency and durabilty, high energy ouput with longer life in severe conditions.

High module conversion efficiency

Half Cell Technology with Module efficiency upto 21.68%. Withstanding harsh environment, high quality leads to a better sustainabie solution even in harsh environments like desert, farm and coastline.

PERC (Passivated Emiter Rear Cell) Technology allows the cell to absorb more light than other conventional cells and improves the modules performance during low light conditions. Shingled Cell Module Design is the way the sliced cells of the panel are connected.

Half-cut cells provide several benefits over traditional solar cells. Most importantly, half-cut solar cells offer improved performance and durability. Performance-wise, half-cut cells can increase panel efficiencies by a few percentage points. Shingle solar cells are solar cells which are cut into typically 5 or 6 strips. These strips can be overlaid, like shingles on a roof, to form the electrical connections.

Essentially the three key advantages of the shingled solar panel design are they :

produce more power,
improve reliability
and are aesthetically pleasing.

EM10505

Shingled PERC technolology has now overtaken both Half Cell and Half Cut technology and is our first oferring of choice.

EM1050004

PID Resistance

Excellent Anti-PID performance guarantee via optimized mass-production process and materials qualoty control.

Excellent weak light performance

More power output in weak light condition, such as cloudy, morning and sunset.

EM10505

Extended wind and snow load tests

Our modules are certified to withstand extreme wind (2400 Pa) and snow loads (5400 Pa). The power generation panel is suitable for household power supply, mountain areas, schools, car charging in parking lots, factory and warehouse power and other scenarios.

How many Panels ?

The number of panels is linked to the number of peak hours of sunlight for your location, this map of Europe shows the equivalent peak hours.

From the graph above the "Daily Totals" is the number of hours of peak level sunlight available each day that is used to calculate the number of Solar Panels needed. So, for exanple, in London 10x 480 watt Solar Panels should produce a long term average power of 3x10x480 = 14.5 kwh per day.
