This 300 watt solar panel is a efficient. Renogy manufactures these rigid and strong solar modules.
The Mono Module works for 24/48V systems.
They manufacture it with diodes installed in the junction box. Also one pair 2.98 feet MC4 cables attached to the solar module.
It uses IP67 Rated MC4 connectors. The connectors are damp-proof and weatherproof.
It does not come with a charge controller or brackets to mount with.
It comes with an efficiency 18.44% and the color is black.
The panels come with high-performance cells encapsulated in EVA.
The heavy-duty aluminum frames provide for strong rigid panels.
One can use these solar panels for many years. You will experience no faults, defects or operating failures.

Residential and commercial rooftop systems
The IP67 rated junction box provides protection against damp and other harsh weather conditions.
There are three pre-installed diodes in the junction box.
The diodes are in parallel with the PV string cells. In the case of partial shading the diodes become active.
These diodes bypass the current
from the non-shaded cells. This limits module heating and performance losses.
The 300 watt solar panel comes without a charge controller.
The panel produces DC voltage. For charging of batteries you require a charge controller. It acts as a voltage regulator. This is to protect the batteries against overloading and surges.
It is important to match the panel output with the controller you want to use.
It is necessary to use an an inverter for changing direct current to alternating current.
To keep the system in good working condition always see that all cables are undamaged.
You have to clean the surface of the 300 watt solar panel with water using a soft cloth or sponge.
Use water and a soft sponge or cloth to clean. To remove stubborn dirt you can use a cleaning agent.
This is to prevent a drop in efficiency.
Other functions to maintain the solar panels should be done by a professional.
These panels are quite large and heavy. It can be hard
for the delivery person to handle them with utmost care.
Unpack and get out of the box on arrival for a quick
The 300 watt solar panel works great. It is real value for money and Renogy offers support that is more than satisfactory.
The module produces usable power. Even during bad weather conditions you still get reasonable output.
