Solar is a great alternative.
The 150w solar panel comes with an efficiency of 18.6%. Phaesun GmbH manufactures these rigid and strong solar modules.
Phaesun GmbH is a German company. Their headquarters are
in Memmingen Germany with their manufacturing facility in China. They
manufacture high quality off and on-grid solar modules.
They call the module the Phaesun Sun Pearl 150 12V 150W solar panel.
The manufacturer of this 150w solar module makes use of shingle cell technology.
For each panel, they use some strings. They connect the
strings in parallel. Each string now generates full module voltage.
Despite the shading of single cells the solar panel still
generates a full voltage. This is because of the parallel connection.
The solar module has a homogeneous appearance with its dark Monocrystalline cells. This is because they do not use surface cell connectors, also known as bus bars.
The 150w solar panel comes with a 90 cm cable that is 4mm thick.
It is IP65 rated ensuring better performance during harsh weather conditions.
On a sunny day with 7 hours of sunlight in mid-summer, you can bargain for the generation of about 890 watts.
That is 7 x 150 watt = 1050 watt.
Now you allow for a loss of 15% and you get 1050 X 85/100
Ignore 2.5 and you get a fair 890 watt.
Nominal current: 8.6 A.
Nominal voltage: 12 V.
Open circuit voltage: 22.5 V.
Short-circuit current: 8.6 A.
Voltage (max): 18.2 V.
Maximum Operating Temperature: +85 °C, +185°F.
Minimum Operating Temperature: –40 °C, –40 °F.
Dimension: 1031 x 785 x 35 mm.
Perfect for mobile applications for charging batteries;
Also to charge 12 to 48 VDC batteries for off-grid remote systems.
The solar module comes with a limited warranty of 2 years on materials and workmanship.
The power rating at standard test conditions will remain
at 90% or more. This is for a period of at least 10 years.
The 150w solar panel is precision made and with high-quality materials. It produces high wattage per square meter.
