blocking diodes are good for combining batteries of different charge levels. Also important for wind systems so the batteries don't drive the wind generator as a motor
@SVAdAstra

Hello Will, Blocking diodes provide one other function: fault tolerance. If a panel in a parallel array experiences a short circuit, only the current from that failed panel will flow into the fault. Without blocking diodes, the current from the entire parallel-connected array will flow to the fault. I install Schottky diodes in series with every parallel panel. the loss is miniscule. This is especially important with "flexible" (bendable) panels that are constructed of flammable materials or may have flammable materials nearby. This has been an issue with the sailing community where fires have been started when "flexible" panels are placed on top of fabrics (Biminis, etc.) and constant flexing fatigues the internal cell interconnects.

Nevertheless it seems that this “fault protection” is not really needed on hard panel.

Nice presentation. 100% agreement with your description of bypass diodes. I would add that the bypass diode also prevents a reverse bias breakdown of the photovoltaic diodes. Which prevents panel fires. 99% agreement on the blocking diodes. Areas of agreement. Don't need them on a single string. Needed them with older charge controllers, not needed on new controllers. Small power loss. Parallel panels facing the same direction not needed. Except I would expect a limit where fusing would be needed. Solf Disagreement with needed on east west roof configurations. I haven't gone thorough analysis yet. So far there does not appear to be a safety issue, there maybe a performance loss. I need to think about this more. Scattered light will create enough volts to prevent current going into the panel. I do agree with the use of multiple charge controllers instead, for maximum power harvesting. One item left off, was blocking diodes prevents electric defrosting of solar panels. This technique uses backfeeding the panels with a constant current source power supply. This method not needed in the Southwest. I have not considered safety issues from rare events yet. Cars backing into trailer mount systems. I need to do more thinking for parallel configurations. Overall positive nod of my head.

Hey Will- talking about bypass diodes. I did some testing to see what it takes for the diodes to turn on and found that when that when that loaded string of (shaded) cells output voltage drops to just less than .8 volts the diode turns on and allows current to fully bypass that that string of cells. The output of that panel or string of cells becomes zero but at least it allows current to continue to flow through the series circuit.

@@jasonbrown467 think of the solar panel as a water pump connected to hoses (the wires). One hose brings water to the pump, the other hose takes it away. Sometimes the pump is off. When it's off, you have other "pumps" connected that are trying to push water through the system. So a check valve is installed between the in coming hose and the leaving hose. That way if the pump is off but other pumps are on the pressure from the other pumps will push water through the check valve instead of trying to push it through the pump that's off. A check valve only lets water flow one way. A diode only lets current flow in one direction. So when the pump turns on, the pressure in the outlet hose is higher than the inlet hose. This pressure difference closes the check valve. Same with the voltage difference created by a solar panel in the sun

Diodes have a voltage drop, and therefore they emit heat. I’ve heard that these hotspots caused by the bypass diodes taking current can shorten the life of these panels. Given that the strings can have 30 amps passing through them, then it stands to reason that the diodes need to be rated to dissipate 15 Watts of heat assuming a 0.5 Volt drop. That’s a fair bit of heat for such a small surface area on the diode.

I actually removed the 10A rated diodes from my two 50 Watt panels (in series). That alone got me from 55 Volts to 70 Volts(2 x 36v). The shading is only relevant at certain hours of the day and is already low efficiency. Mine are stacked on top of each other in portret mode and I discovered that panning them on the Y-axis (horizontal angle to the sun like a door) produces a lot more also. It seems that some panels have difficulty absorbing direct sunlight shining exactly straight on them making them hotter reducing voltage, that is what I discovered.

I like to always use bypass diodes, as you said, to avoid the back flow of electricity from a panel to the other (panels have great resistance to electricity, and it will be loss as heat). But also, while this should not happen with good controllers, cheap chinese controllers may allow the backflow of electricity from the battery to the panel(s). This is very easy to check, because it will produce a considerable loss in battery voltage during the night.

At 2:52 the diagram for blocking diode is an example how NOT to use them. The panels should have been in parallel. Internally the panel should also have bypass diodes for each cell to avoid hot spot damage due to reverse bias current when a panel is partially shaded. A panel with 144cells that's wired internally as 72s2p also should have internal blocking diodes in series with the 72s before internally connecting the two cell strings in parralel.

Thanks! Very interesting to hear about these aspects that I had no idea existed! I suspect my PWM is allowing current from the battery to go out to my single solar panel on my boat, as I read a low voltage (4-5V) when connected despite totally covered and turned upside down. Maybe a diode would be helpful there.

Nice diode roundup Wil! Thanks. Would you recommend that if I have two MPP Solar units hooked together for split phase operation and I have east and west arrays it would be best to hook an array to each MPP rather than using a diode combiner? Mike I did see that crazy illusion with the black diamonds jumping all around. Funny they disappeared when you looked specifically at them.

@@WillProwse No he didn't. He did some experiments about the diodes when he bought used solar panels some time back, not yesterday. BTW I think Will's explanation is much clearer. I think ideally we should have a bypass diode for each individual cell, may be not economical/practical though?

A very nice, straightforward explanation. 👍 from Wales U.K. 😀🏴.
