That gleaming review of NewPowa panels has just about convinced me to make the purchase....they fit the space I have but had not seen any "real world" reviews...thank you for the information...I'm ready to purchase panels now.

Thank you for the great advice. I will try to purchase the 250 watt or the 220 watt panels and go from there. I would like to be as self-sufficient as possible without shore power. I have the ability to connect to shore power now but free charging is the goal.

Sorry, yes 1(for now) 12v 100ah timeusb lifepo4..

Question for the great minds here...I am about ready to purchase solar panels and wondering if more IS better? I only have room for 2 panels on the roof of my converted cargo trailer. I am considering the 250 watt 12v Rich Solar units however I have seen several 200 watt panels that I am...

I am an absolute beginner at solar and all it encompasses which is more than I have anticipated it was going to be. I'm not afraid of a challenge or the work that comes it. Just looking for good sound advice from someone who has been there and learned and has real life experience to share.

Does anyone have a "go to flat panel or a stay away from these panel" I really only want to this once..maybe twice...I'm 69 and REALLY don't want to do it more than twice.

I think I have resigned myself to getting new panels. Now for the $64,000 question. I am leaning towards 2 200 watt panels so I would have room for 2 more if need be on the roof. What panels would you suggest? This is a twofer for my $64,000 ...my plan for mounting would be unistrut the...

Ok the pictures I am posting are in order right front, right rear, left front, left rear..not sure if it makes a difference

Oops I knew there was something I missed...I will have those numbers in 10 minutes....

More numbers for y'all to digest. The panels are grouped in pairs and I tested each panel separately and I will list each. Right front 2.0 amps, right rear 2.7 amps, left front 2.8 amps, left rear 1.8...left rear is beginning to delaminate/wrinkle. The right side I washed and the left I did...

Sorry if I wake any of you up this early on a Sunday BUT before I take any of the connections apart I have a couple of questions. It appears that the right 2 panels are connected together and the left 2 panels are connected together. Meaning that the positive on 1 right side panel is...

The sun is setting and everyone has giving me great advice and lots of things to look at and test. The person I purchased the trailer from used a power station ..either a Bluetti or an ecoflow...I'm thinking I can do better and custom build a system that would be best for our needs and be able...

After watching the video I think I will disconnect all the panels and test each individually and if everything is close to one another I will continue with the project if not I will be back here for more AWESOME ADVICE...

I set the multi meter to dc amps red probe to the red wire in the connector and black probe to the black wire of the connector

Correct a multi meter..so the question is the voltage and amperage within acceptable for me to continue on with the project of battery, charge controller and inverter ?

I haven't gotten to the point purchasing parts yet. Again I am sorry for ignorance of terminology. I have 4 panels in total. There are "Y" connectors connecting 2 panels together and those are connected to the other 2 panels then the 2 sets of panels are connected to a "RED and BLACK pair of...

Sorry for the poor panel picture but the sun had a huge glare on the screen I was able to see what I was looking at. It shows 2 columns and the 3rd one is on the right. The rows have a half cell on each side and 4 full cells in between.

I'm not sure exactly how count the number of cells BUT it appears to me that there are 3 columns of 60 cells so 180 cells per panel x 4 panels = 720 cells i am attaching pictures of the panels and volt and amp readings at 4pm central time near corpus christi tx.

There is a barcode that I can try and get a clear picture of if that will help.

As best I can tell they are TP/SOLAR this is What Amazon has listed that best matches the panels I was told they were.

Ok I do not have any paperwork on the panels and the are already glued on the roof so looking for a label on the back in not an option unless I absolutely have to. I will climb on the roof and see what I can see but they have been on the roof for 18 months already so things will mostly be faded...

Hello everyone and a thank you for the awesome advice I am going to receive. Here's my question(s) 1. I have 4 panels on the roof of a cargo trailer I purchased and decided to check the voltage output. Much to my surprise I got 36.4 ...I'm confused about that number. Do I have a dead panel ...

Sorry if my frustration shows. Here is the deal, I have 400w Solar panels and that is all I plan to have. I will buy or build a 100ah or 200ah or bigger lifepo4 battery to run minimal lights and charging ports and 1 roof MaxxAir fan. This is all I want in the small camper. Anything more than...

I guess the bottom line is I have 4 100 watt panels on the roof and cabling inside the trailer. I do not plan to change the panels or add to it as they are covering the roof now...so I am asking i need next. Do I just add up all the listed watts for the items I plan to have in the camper ? I am...

Ok, this is my thoughts. 12v will be the primary usage. It will be used to charge devices and run led lights more than likely a small cooler. I have a 400 watt aray that is already installed on my 6x10 converted cargo trailer to camper. I have been reading Wills suggestions for a small system...

Ok I think I am committed(or should be committed) to building my own solar system. I've been watching come of Wills older videos and would like real user real world advice on the best not the most expensive MPPT 50 volt 20 amp and 1000-1500 watt inverter and real life recommend 100ah-200ah...

Its the power supply that comes with the cpap unit...I'm going to see if we can get a second cpap that is better suited to the 12vdc system.

I was thinking about the Bluetti EB 120. At this point I am looking at a 12v cool with no freezer, 6 -3 watt led puck lights, a MaxxAir roof vent, a 12v TV probably with its own battery to be charged as needed, 2 -3 battery powered fans that will be charged as needed, 6 to 8 USB device ports 1...

I have received great food from thought...here's my next question. Which is the better option? 1. Build a complete system less the solar panels...meaning purchase the solar charge controller, wire and terminals and what ever else is needed OR 2. Purchase a complete solar power station with all...

While waiting for some awesome advice I found a calculator(Renogy) that that says about 350 watts with 400ah battery(s) could last 6 hours and recharge in my 5 ish hours of full sun time. So now I need to check ALL items I plan to power with 12 v that I will fudge up 1 full number. Next...

The thread title is a good indication of my experience. This is the question for the great minds here. The advice i am looking for is what do I need to build a complete solar system to run. I understand that specific watts and amps will be needed to be more precise but overkill is an excepted...

I plan to connect my 400w Solar panels to my system BUT can I add a wind turbine to it also ? We are in south Texas and the Wind rarely stops here...cloudy days are somewhat common and enough to prompt me to ask about wind turbine. Yes I understand that this is a Solar forum but I am sure I...

I could do all the research but I prefer to have real world/use advice. Here is our thoughts, I plan to install 4 possibly 6 led puck style lights, a Maxxfan roof vent fan, 1 possibly 2 120v outlets 1 dedicated to a cpap machine the other to a switched outlet so only hot when switched on. I...

Air conditioning, sorry... I knew what I was talking about lol.

So basically if I want ac I will need shore power or a generator......
