6 Frequently Asked Questions about “Solar charging backflow”

Can a Schottki diode feed a battery charger to a solar panel?

I have a solar panel and an external power source feeding into a DC converter (U10) that are both used to feed a battery charger (U2): In a previous design I used 2 schottki diodes to prevent back feeding from solar to U10 and from U10 to solar.

Why do solar panels need a blocking diode?

There is a possibility of the current flowing from the battery to the solar panel, thereby discharging the battery overnight. To prevent this from happening, a blocking diode is installed. It allows the current to flow from the panel to the battery but blocks the flow in opposite direction. It is always installed in series with the solar panel.

How does a DC-coupled solar & storage system work?

The sun hits the solar panels which in turn push energy through conduit through an inverter. In a DC-coupled Solar + Storage system, where a battery is installed in front of the inverter along with the PV, power can flow either directly to the grid through the inverter or to the battery where it can be stored and later discharged to the grid.

Will charging a lower voltage panel harm the panel?

You will not harm the panel by charging a lower voltage panel. The battery will "clamp" the panel output to the battery voltage and supply whatever current it cam. You should add a diode between panel and battery to prevent "backflow" when panel voltage is lower than battery voltage.

What happens if you push an electrical charge into a PV panel?

Pushing an electrical charge into a PV panel can damage the panel. Unfortunately, in certain Solar + Storage or PV repowering situations, this damaging result can occur.

How to prevent back current?

To prevent the back current in this solution you will simply add a diode (perhaps some Schottky's) in series. If you will use L7809 as a voltage regulator, you could not prevent some back current, I'm afraid. Look at the internal schematics in PDF for details. You will lose the current through internal output resistors etc.
