This 400 watt solar panel: It is to be to be very efficient

4 x 100Watt solar panels4 x 100 Watt solar panels.

A 400 Watt Solar Panel that is a high performer. Distribution of the rigid and strong modules is from Renogy. 

They call this high-efficiency panel the Renogy 400W Monocrystalline Starter Kit. 

This system uses 4 x 100 Watt solar panels to deliver a peak output of up to 400 Watt on a sunny day.

The module comes with an efficiency of 21%.

The four 100w panels take up about a 3ft x 8ft space.

You can connect the four Renogy 100-Watt Monocrystalline solar panels in parallel.

Do it by making use of three pairs of branch connectors. The branch connectors come with the kit.

It has a  TPT (Tedlar Polyester Tedlar) back sheet. This  ensures smoothness of performance over a long period.

The heavy duty anodized aluminum frames  provide for high in quality panel rigidity.

You can enjoy faultless operation  for many.

This 400 watt solar panel comes with a very good  warranty for as long as twenty five years.

On a sunny day in mid summer, when there is  6 hours of sunlight, the panel can generate 2 Kilowatt power.

This is 6 x 400 watt = 2.4 Kw.

Allow for a losses of about 15%. Now you have  2400 * 85/100 =  2.04 KiloWatt

Throw away  0.04 and you have 2 Kilowatt.

Operating the 400-watt solar panels

For full operation of the  400 watt solar panel  we need a battery , inverter and

 a charge controller.

It comes with a 30  Amp charge controller.

Divide total watt by volts to size the battery

This is 400 watt x 6 hours daily sun ( Depending on season and area.) X .85 for loss divide by  12 volt x 2 for D O D.

You get 400 x 6 x .85 / 12 * 2 =  340 Ah.

Use  2 x 200 Ah batteries.

Decide the max watts to utilize and size the inverter.

Max out is 400 watt. 

By rule of thumb you will use an inverter one and a quarter  to one and a half times more than max requirement.

We use a 400 * 1.5 = 600 watt. A 600 watt inverter is a good choice.

Connecting the charge controller

First you will connect the battery, then  the load and lastly the panel.

This ensures safe operation and it safeguards the  equipment against overload.

One should never connect the solar panel to the controller without a battery.

It is good practice to install the charge controller indoors to keep it well ventilated, cool and dry. Keep the controller away from damp.
