50 Watt Solar Panels 50 watts panels are great for portability. You can put one in the truck for camping trips. Even put one in the window that is closest to direct sun. And prices have been coming down. Most these days come with heavy duty fittings also.

You can run things like 12 volt fans, solar pumps with no problem. Expand-ability is always an option. You can start stacking them as you get more room. If you live in the country, solar operated access gates are nice and 50 watts usually work well for this application.

A 12 volt 9 amp battery can be fully charged off a 50 watt solar panel during the day and will give you 3-4 hours running something like 10 watt lamps. Like the LED variety. It is advised to use a regulator in this type of situation.

There’s a Renogy 50 watt 12v panel on amazon that gets good reviews. A lot of the buyers are saying it’s the best they could find in a 50 watt using mono-crystalline cells. They have MC4 leads coming out of the panel which works with the MC4 adapter kit by the same company so the hook up can be straight forward. (and secure) One person had just one mounted on the roof of his house and loves it for quick top offs and such. the dimensions: 21.3 x 1.2 x 24.8 inches Item Weight 9.9 pounds

The build quality is what these panels are known for at this point. If you’re on Amazon prime you can get one in 2 days which is nice. With the hurricanes this year and living near the coast this is good for the last minute ” do I need one more panel?” After you collect so many panels over the years you start recognizing good build quality when you see it. Especially when it’s not laying flat against something as in mounted by 2 brackets or situations like that. People were also impressed by the output the panel gets even before they can get anywhere near direct sunlight.

Like one new 50 Renogy panel doubled the output the person was getting from another 50 watt panel. Charging a 35ah 12 battery in a few hours.

The supplied hardware and wiring is good quality also along with the anodized aluminum parts. The packaging is nice and protective. Isn’t it funny when you get something like a panel in fedex and the box is packed in such a way that if it took a shot from the wrong direction it would be DOA at your house, not with Renogy according to several posters.

I love these quick and dirty setup videos. I can get ideas for other projects. I like the way he used the old computer case to hide all the components. Also what I never thought about is the air flow holes in the top of the case make it convenient to tie wrap small components down for testing.

this is just quick bit 50 watt solar backup setup this is a renergie 50 watt panel puts about 17 volts out Oh about 20 volts open circuit I know this isn’t the best location but it gets enough Sun for I use it for charging cellphones and stuff it has a those mc4 connectors that come down into what is a PC case on the top I have a five volt USB power regulator as a built-in multimeter and eight 220 watt peak yeah DC to AC power inverter about it’ll handle 120 watts continuous I got this for like five bucks at Walmart so I can’t complain how it performs it does a pretty good job as another USB connection on it is one of those horrible universal plug though that all the plugs want to fall out of okay on the inside here I have the solar panel coming in with the way oversized wiring this is like what is it 10 gauge I think yeah 10 gauge and it comes into this 10 amp charge controller this is about 10 bucks at Walmart I just get the parts wherever I can get them cheapest for this and they’re connected up to these batteries it charges these two these two scooter 12-volt scooter batteries they’ve seen a lot better days this one right here feels pretty cool but this one feels almost hot so this one has a pretty high internal resistance would probably work better if I just completely took this out and only ran on one battery but yeah it’s just wasting most of the power it’s taking in from heath even though it’s only at 13 point 5 volts right now I have a positive here it’s kind of a makeshift wiring but it works when I get better batteries all wired up better I by negative here I ran a black wire side to use a red wire for my negative on this this goes to the power inverter I connected up to a breaker so if it pulls more than 20 apps it blows the breaker and then the positive goes straight into the inverter and then these two what our speaker buyers I fused temporarily like that with it the 5 amp usually think now it’s a 20 amp fuse but I should put a 5 amp in there that goes up to the 5 volt regulator this will do 3 amps at 5 volts it has a USB connection and you can also connect up wires up for a 5 volt output which I did do and they’re wired to the USB connections in the front of the case and I was I did have a switch connected this so I could leave the inverters plugged into the breaker because I don’t want it to pull any power wins just sitting here but all the switches I had none of them could take 10 amps or more so I would have to find a switch somewhere that’ll take 10 amps but I’ll pry do more videos on this when I do a less makeshift set up this is a right now this little this’ll charge up my little Chromebook it’ll uh me see if this will focus here it’ll charge up my Chromebook it’ll power my router and and my modem they’ll charge phones and stuff just little things but I really do need better batteries these are pretty much toast thanks for watching uh maybe I’ll do some more videos on this kind of stuff later if anyone’s interested
