how's it going you guys this is Scott with everyday solar today we're going to test out two of the most popular brands of 100 watt panels closer to me we have Eco worthy 100 wat panel and then reneges on the far side additionally I did get your feedback and we'll add some additional testing including a pretty interesting durability test to this round of testing to get you guys the information you need to make the smart decisions on your own DIY solar setup so let's jump into it so kicking off the day the first trial and it's looking like a glorious day for some we have a sun's out and the skies are clear now these 100 W panels are sized to produce 100 watt under standard test conditions what does that mean that means an ear Radiance of 1,000 watts per meter squared and also a temperature the actual panel temperature not necessarily just the outside temperature of 77° f or 25° C so I have this Fluke meter here and remember we're just getting started these panels are facing south and what we're seeing is our ear Radiance is at 700 watts per M squar and the panel temperature is heating up but we're under 80° F so right at standard test conditions for the temperature so the panel is not degrading much but because the sun is still lower in the sky we're not up to our full IR Radiance and I would expect that to go up substantially and we'll take multiple more points throughout the day but let's see what that's bringing in in terms of power in our Delta 2 and Delta 3 units so just plug things in on the Eco worthy for this side and we're using these little power meters to get our voltage and amperage but also in the lower left hand corner you'll see the wat hours those will accumulate up throughout the day and that's really how we're going to compare we can do spot checks here on the power so we're right at about 65 Watts but we really want to accumulate up the energy throughout the day so if any clouds move in or just conditions change it's going to be the same side to side so the eorth is going to be going through the same thing as the renogy so then we got the renogy over here right before 10:00 a.m. so we're not going to be producing the most we're going to see throughout the day hopefully we'll get these guys up to 100 Watts but looks like Renegy is around the 75 and you can see the voltage and amperage difference and again lower leftand corner that Scrolls through there's our amp hours and then ultimately we'll be comparing during the wad hours so we just finished up the morning side of the testing and now I'm moving on to the afternoon and then both of those will be about 2 hours each two to two and 1 half hours now let's look at basic dimensions and a few of attributes for these panels we have the E worthy here that's going to be 23 and E of an inch wide and 35 and 3/4 in length with a overall area of 827 Square in and that is 12.2 lb comparing that to to renogy renogy is 20 and 78 and then an overall length much longer at 41 and 7/8 total area of 874 Square in so Renegy is going to be the panel with the larger surface area we'd expect a little bit more power output and then 13.8 lb but let's go ahead and turn these around so this one's our Eco worthy we popped off the cover it is ip65 rated we have our soldered connections up top the two dodes between the three sections here and then we have our positive and negatives crimped and soldered on the bottom so now let's take a look at the spec plate so the critical parameters you'd be looking for to design your system we have our open circuit voltage at 22.7 volts short circuit current at 5.55 amps and then for a maximum PowerPoint that'd be more like a 19.5 volts and a current of 5.13 amps now I'll put all this information together in a t at the end of the video and I'll compare to all the other 100 wat panels we've tested so now we have the renogy cover plate off also ip65 rated soldered connections up top just like the ecoworthy two diodes and then we just have crimped not crimped and soldered so some were people were arguing that crimps better than solder now crimped and solder I'd say would be superior but a properly crimped connection should have no problem and hold up to vibration over time then looking at our specs plate here open circuit voltage for Ren 24.3 shortcircuit current 5.21 and then our maximum power point for voltage would be more like 20.4 and a maximum PowerPoint Uh current would be 4.91 now the only other thing I'll say from a design perspective I do like the rangji has these small plastic caps in the corner I think that'll help for durability oppose just your analyze aluminum rails with a miter cut which is more common for some of the different panels you'll see also the the lead length the wire lead length is much shorter on the renogy than compared to the E worthy so depending on how you're wiring these up you might have to make small pigtails to extend out this and put your panels in series or parallel while ecoworthy with this extra length you wouldn't now we'll roll everything up into tables and the one thing I will put in there is the wire length the wire lead length and that'll be measured from the end of the mc4 up to this connector here and then you'll be able to compare those from Brand to Brand so just finishing up the testing now for our second of the two trials throughout the day and we are getting some interesting results there's definitely a gap between these two and I've rolled that up into a table I think that table is going to be super valuable for you guys and we'll also make it so you can download it because depending on when you watch this I'll include pricing pricing might change so it'd be good for you guys to be able to change that and then that will help you with your purchase decisions but also I've been thinking through durabil ility test and we always talk about hail when it comes to solar panels so I wanted to figure out how the heck can I actually replicate a massive like baseball-sized Hailstone hitting the panels to see if it has any damage so what I ended up doing is taking these massive like cocktail ice cubes 2.5 in in diameter and I froze those in the freezer and then I took a little league pitching machine that maxes out at about 55 m per hour I only had six of these ice cubes so I had to be pretty accurate and got two test throws that actually missed the target so then we just went right into it with the third Ice Cube and was able to hit the Eco Worthy on the lower portion of the panel the second try on the Eco worthy we also hit the panel and then for the Renegy we had two direct hits as well so what I wanted to do obviously inspect the panels and they look perfect the things are insanely durable that they can take a hit like that so no visible damage was done but what about how they perform so I took the ecoworthy and the renogy and I swapped them out I saw what was each of the brand new panels that we were testing at the end of the testing for the day what do they produce then I swapped it out with the panels that just got hit with two chunks of ice to see if there's any difference and there wasn't they are still producing the same amount of power for the Eco worthy and the renogy so no damage was done and I would say both of these guys passed with flying color but give me some feedback what else do you think we should do in terms of a durability test on these solar panels I want to kind of get that standard testing procedure put together that gives you guys the most benefit to help you make an educated decision for your own project so now let's jump in and take a look at the results so 100 watt panels as you probably know are super flexible the amount of projects that they actually can come in handy for is very wide but it does not not stretch all the way up into offsetting your home's energy consumption to do that we're looking at more like 400 watt panels and most likely a professionally installed system if you want to start where I started there's a link in the description and with a little details on your home and your monthly power bill within minutes you can see what size of system would I need and how much roughly would that cost if that's within the ballpark of what you're looking for they can even connect you with installers in your area and you can start vetting those installers to see what is the right partner for are you going forward now I also did a project that saved me a ton of money because I took on the later I did the DIY project with a company called project solar they helped me with the designs the engineering prits pulling the permits sent me all the materials then I went to work documented that whole process and then we got it inspected and got our permission to operate that allowed me to lower my dollars per watt to get my monthly power bill offset so that link is also in the description if either of those two paths are in your near future so let's start looking at these results and I also brought in our other panels that we just tested last week so we brought in the Thunderbolt from Harbor Freight and Rich solar and I also included what you guys asked for so this exact Spreadsheet will be downloadable there's a link in the description along with all the other links for the panels the exact panels that we're using here but the Renegy and the ecoworthy is what we actually tested today I brought in the prices over the last 12 months the low the high and then the average price the average price is what we're using for some of our calculations and then this average power in watts is actually what we measured there is another tab down here in the spreadsheet and in that tab is all the detail on the testing so we have what orientation we are facing south what was the actual angle tilt angle of our solar panels and then we have test one and test two how long was that test and what did we measure in terms of energy that we able to put into the ecoflow Delta 2 and the Delta 3 then that gives us our average power so that is where I took my morning session which is test one and my afternoon session which is test two and I average those together I additionally for renogy and ecoworthy have e Radiance at start and finish and also panel temperature I did not get those for Rich solar and for the Thunderbolt but I will add those later on as we're going to continue to do more and more tests so going back to our resultant table we can actually start to compare apples to apples so what we want to do is we see the average power now the renogy had great results so it averaged out 96.2 Watts across the over four hours of testing that is amazing for a 100 watt panel now we also had amazing conditions today but the Eco they came in at 85.5 that's a significant hit now in the past we just took the two numbers and then that's where we got our percentage but you guys asked to actually start breaking that up here and also asked what's the performance on shaded power so I did do a small shaded test where I made a little cardboard Leaf in the lower right hand corner and I blocked a couple of the cells on each panel right here you'll see 32 out of 90 so for that test the renig was producing 90 Watts then I shaded it and it only produced 32 so it took a massive hit the ecoworthy was producing 81 Watts at that time I shaded it same size leaf and It produced 42 so the ecoworthy actually did better in the Shaded test now the metrics you'd want to look at when you're sizing out a system especially if you have like an RV application and that roof is a limited amount of area so we took average power per square foot from our actual testing data not from any advertised power but what did we actually test testing and we we can see from the Thunderbolt and the rich solar we at 13.3 and 14.1 but the Renegy did great so it was up at about 15.9 and the Eco worthy did well as uh compared to our last two at 14.9 so Renegy does have the advantage here and you're going to get the most out of that square footage when it comes to the reny panel compared to the other three that we tested now what about price maybe price sensitive maybe what you're doing you got to really keep that price down that's where you'd want to look at this column and that's going to be average price for the power that you produced and here you can see the Thunderbolt although the Thunderbolt does really well and produces a lot of power it also costs a lot and it comes with sa connectors one thing I didn't mention you can actually hit this plus sign over here and expand out to get additional details on each of these panels what is my width length overall area where you using that area right to do our calculations weight VCC ISC uh lead wire length how long are those wires so you know and then what kind of connectors do they have so I just take that and I put it out of the way so we can actually see the results so back here here's your power or here's your price for the power right so it's a17 and I do need to I'll change those units it's $17 per watt that is the label here for Thunderbolt and one 08 for a rich solar you want it low you want it as low as possible in terms of getting bang for your buck when it comes to these panels Renegy very respectable at a 086 but because e Worthy is so low on their pricing and you'll that link right over here in the table or the link in the description you'll see they actually offer good prices all the time and every once in a while they have a price all the way down to $50 for the 100 watt panel so you'll they're all the way down at 73 which is best in class thus far for the four panels we've tested so don't forget you can download this sheet why that would be valuable if you're watching this 12 months or 24 months in the future maybe that average pricing or price has changed you could download this you could go ahead click all these links get your updated pricing and you enter it in that sell and then you're going to update your Fields over here to give you that Benchmark where you can compare them side by side now if you're just getting started in solar and you need a little help on wiring series wiring parallel and then when would you do series parallel you can check out this video right here and I'll walk you through all three use cases so you can apply that to your own project and then if you need to actually land that into a portable power station which is a very common application you can check out this video right here and we'll try to get the maximum solar input power into our ecoflow portable power station so thanks for joining this video don't forget to let me know your feedback down in the comments and we'll catch catch you on the next video take care ...
