What is a 180 watt solar panel?

This 180 Watt Solar Panel includes Monocrystalline solar cells (A-class). The solar panel is very powerful and is very suitable for charging batteries and solar generators on the boat, gazebos or camping. It is weatherproof and waterproof and can therefore be permanently mounted. The 180 W solar panel has a universal MC4 output.

Is the 180 watt solar panel waterproof?

It is weatherproof and waterproof and can therefore be permanently mounted. The 180 W solar panel has a universal MC4 output. Via this output, the solar panel can daily generate an average of 850 Wh of energy. You can store this energy in a solar generator or 12V lead-acid batteries (in combination with a charge controller).

How much power does a solar panel use?

This means that the real world performance of this panel is between 175W and 185W Max Power Voltage (Vm, or Vmp) The Vm is the voltage produced by the panel when it is operating at maximum power. If you have an MPPT solar controller, this is the voltage that power will be drawn out of the panel at when it is performing at it's peak.

How efficient are enerdrive 180W solar panels?

Using the Enerdrive 180W panels as an example The 180W panel specification sheet lists a panel efficiency of 17.8%, which matches our calculated efficiency . Panel efficiency is not particularly important when planning your solar array, but it can help you confirm that the specifications listed on the panels you plan to purchase are legitimate.

How does temperature affect solar panel voltage?

The voltage of solar panels also has an inverse relationship to temperature, which means that an increase in temperature means a decrease in voltage and vice versa. This relationship is measured with the temperature co-efficient of Voc. In the case of a the Enerdrive 180W panel, the temperature coefficient is -0.30%/˚c.

How many enerdrive solar panels do I Need?

It is not a relevant number for most off-grid applications because it will usually exceed the maximum input voltage of an MPPT solar controller and require you to connect a massive number of panels. In the case of the Enerdrive 180W panel, you need to connect 40 panels in series for this figure to be relevant. Testing Conditions
