    For a person new to these concepts, comparing a solar panel to a battery (AA for example) can really help to bridge the concepts. They can use a couple of batteries and see how connecting in parallel vs series changes the voltage. Then the solar panel discussions can make more sense. Thanks for the great intro video.

    You can eliminate the whole series panels going down in shade with a bypass diode. This should always be included in a series wired install so failure of one panel does not stop the output. Generally running panels in series up to 300vdc sections in series is best bet for reasonable controllers. Heavy parallel amps creates a lot of heat and requires heavy duty controls

    I have my panels set in sets of 9 240 watt panels. Having do a lot of heavy electrical work. I took my panels and set them up then I took a large cardboard and covered a panel I lost the out put from that panel and nothing more. I also covered just a spot of one panel and I lost about half of that panels out put. I have contacted the builder and they said all of there panels made over the last 10 years have bypass diodes built into them to reduce the lose. Now what I have found is two of my sets of 9 panels are then tied together and then I would block off one panel in one group of 9 and it dropped at the combiner the output of doth sets as if they only have 8 panels working together.

    You should consider that The search for flexible panels had free shipping. When I went to buy panels, a 300 Watt framed panel was $120 which seems fantastic. But they ship exclusively through freight shipping; that ended up being $260 for shipping one 300 Watt panel. I ended up going for a flexible 300 Watt kit for $360 with free shipping.

    @todddunn9456 жыл бұрын

    Nice job except for two things. First, your comment about controller capacity is somewhat misleading. First, if you are going to wire your panels in series or series parallel you will want to use an MPPT controller NOT a PWM controller. In that case you need to look at the maximum solar array wattage that the MPPT controller can handle AND the maximum open circuit voltage that the controller can handle. For typical 12 volt panels the open circuit voltage is in the 21.5 volt range NOT the 17.5 volts you mention, which is the operating voltage. So when picking an MPPT controller for series or series parallel wired panels you need a controller that can handle your total system wattage and the total open system voltage for your array as wired. For example, four panels wired in series will have a maximum open circuit voltage of 4 times 21.5 or 86 volts, so you need a controller that can handle at least 86 volts (say a controller rated for 100 volts) Another consideration is that the amperage rating for MPPT controllers is typically the charging amps NOT the panel amps. For a series wired array the charging amps can be estimated as array wattage (say 600) divided by charging voltage (say 14). So for the 600 watt array 600/14 = 43 amps, so you would need a 50 amp rated MPPT controller to handle a 600 watt solar array. Second although your graph showed the dependence of wire size on amperage AND wire length you completely forgot to mention length in your discussion. Wire length is a critical parameter in choosing wire size. The longer the wire run the larger the wires need to be. I say this is critical because someone listening to your video might come away thinking that wires should be sized based on amps alone. That can lead to a very unsafe setup. I say unsafe, because under sizing the wires can cause a fire. Other than those two details a very nice video.

    Gary Hornbuckle, you've got it reversed. Increased wire resistance will cause a VOLTAGE drop, NOT a current drop. Current is the same at all points in a series circuit. Ohm's Law says P = I*I*R. For example, if a wire carrying 8 Amps, has a total end-to-end resistance of 0.1 Ohms, the power dissipated in that wire will be 6.4 Watts. Decrease the resistance by making the wire larger, say to 0.05 Ohms, and that wire will dissipate 3.2 Watts. If it weren't a safety issue, then it wouldn't be an NEC violation to protect a branch circuit in a house comprised of AWG 12 wire with a 40 Amp breaker. AWG 12 wire is rated for 20 Amps max. The wire will eventually overheat and cause a fire long before the 40 Amp breaker trips.

    Its voltage drop that is the concern im going to be lazy with the figures but you will get the point Say you have 2000w solar system at 100v 20a and you have 10v drop over your cable well the charge controller will still see 20a but now only 90v so your useable power is 1800w it doesn't matter where on that circuit you test there will be 20a as for any danger well no if the cable is made for 20a it will be fine just wasteful, now i know what your saying about the cable affecting series resistance but it is such a negligible amount you never worry about it a 2mm or 12 gauge wire which is rated 20a is .5ohm per 100m or roughly 330feet which you would never do with a cable that size

    A total run of 100 meters wouldn't be too difficult. Don't forget you have to count both the supply side and the return side of a wire pair. So a 50m run of 2 conductor wire would effectively be 100m. My house is 120 feet long from end to end. My load center is 28 feet from one end of my house. There's four runs from the load center to a room at the opposite end of the house aproximately 90 feet away. Adding another 3m for vertical travel, i.e. from the load center to the attic and the attic to the receptacles, the total one-way distance for each of the runs is ~100 feet. accounting for the pair, that's 200 feet of wire per run. So while a 100m run is not likely to be a common occurance, it's definitely not difficult to do.

    Great video! You covered the basics quite well! I would only add that, when comparing poly and mono panels, the panel power ratings may be the same for full direct sun, but the poly panels perform better in less than ideal conditions, like partial cloudiness or a shallow angle to the sun. This difference can be significant over the long term. And, it can best be measured by looking at total daily solar production for both mono and poly panels added up for thirty days, then averaged by dividing the total production for 30 days by 30 to get the average production per day under identical but less than ideal conditions. Then, subtract the totals to get the difference. Spoiler: The poly panels win.

    Thanks for the info. Btw you didn’t mention about the big difference between mono and poly. Mono are designed to be exposed perpendicularly to the sun rays, the crystals are oriented all in the same direction. Poly has multiple oriented crystals, so less efficient compared to mono at 90 degrees but more efficient in any other angles. I think polys are best in winter, northern regions and places where the sky is cloudy the most of the day. This is what i found reading over internet but if i’m wrong or i’m missing something as technology improvements, feel free to correct me (sorry for my broken eng)

    Ran across your profile researching solar energy on KZread and want to pick your brain. I am renovating a 100 year old underground storm shelter and have made it to the point of installing a solar setup for a couple reasons. 1-power an exhaust fan and intake fan(12v PC fans inside 4” duct work that exit through ceiling) 24hrs day for air exchange and also for a few components that would only be used in a power outage (led light strip, interior circulating fan, maybe a small 12v heater.) I purchased a small kit from amazon see pic below. It’s a 20 watt panel, solar controller. I also purchased a 300 watt inverter, 20AH 12v battery. As my little projects normally do, they become way more than originally planned. Now I have a second 20AH 12v battery in route and Another solar panel, the 2nd one being 50 watt. I have built a removable panel that hangs on the wall that houses the batteries, solar controller, inverter, switches and a fuse block. After watching your video I know I want to wire the panels in parallel so they work independently even if one is in shade during a time frame in the day. I haven’t thought about the batteries and their wiring together yet. The solar controller is a 10amp pwm. I already want to upgrade this because I don’t think the low voltage disconnect is working as it should (battery drained to just under 8 volts during a two day cloudy period and fans were still running. I’m questioning my wiring for the switches. I connected the load from the controller +\- to the poles on the fuse block and wired off the accessory poles (see fuse block pic) to the components (pc fans, led light, etc. the switches do power the components but I don’t think this is right and may be drawing more energy from the battery. My battery is also wired to a master switch on the panel. Do you have any suggestions,thoughts, best practices knowing what I’m attempting? Knowing that I have two solar panels totaling 70 watts, 2 X 20 AH batteries, a 10amp controller, and my components, what replacement controller would you suggest or features to look for in one? I definitely want low voltage disconnect.

    An excellent presentation, a well done video, I just wanted to point out a way around the loss when running panels in series and one getting shaded, The reason for the loss when shaded is the fact that an unlit cell is almost an open circuit therefore allowing the rest of the cells to reverse the polarity of the shaded cell or cells, however most of the newer high quality panels have blocking diodes across portions of the panel as they cannot put them across individual cells as the forward voltage drop of a standard silicone diode which is 0.6 to the threshold and as high as 0.9 at it's full rated current, is greater than the voltage produced by a single cell which is 0.5 nominal depending on cell temperature. The easiest way to get a series string of panels to operate just like the parallel panels do losing only 25% when one panel is shaded in a group of 4 as he is showing, is simply to place a shot-key bearer rectifier diode across each panel, as they only have a 0.3 volt forward voltage drop to the threshold and will be less than 0.5 volts at full rated current making it equivalent to the loss of a single cell.
