Cheap VS Expensive Solar Panels | 12v Touring | Project Cyan

Published on Jan 29, 2019 1,365,819 views

Looking after your deep cycles batteries that you spent so much money on is important to ensure a good life span, solar panels allow you to keep them constantly at full charge while your touring.
Are expensive solar panels worth it? is there anything wrong with using cheap solar panels?
In this video I test a cheap solar panel from Sunyee and a expensive panel from a local store called Itechworld. Also in this test we see if having an MPPT solar regulator is really does give your more amps over a PWM regulator.

  • James Tan
    James Tan 1 month ago I'm just speculating but the reflective coating may improve the lifespan of the panel or make it easier to clean and upkeep. It could also reflect unnecessary wavelengths that may degrade components in the long run. It'd be really interesting to see how well these two stack up against one another in a few years time.

  • j mcmann
    j mcmann 1 month ago (edited) not really...mathematics begins where variables start..the exact answer isnt the goal....arithmatic is just a variation on the only operation possible ..addition..the other operations are variations of addition..6x7 means add 6 to itself a total 7 times as an cannot go into the forest and multiply rocks but one can add could argue math begins at anything past straight addition i suppose
  • maixck
    maixck 1 month ago @j mcmann You could argue that but you would be wrong, Arithmetic is just a branch of mathematics that studies numbers and basic operators. And the part about variables? no, that's Algebra, you know, another branch of Mathematics.

  • Laurence Warriner
    Laurence Warriner 3 weeks ago @Michael Metzler Sr This is a regional thing. For the word 'Mathematics', most of the world uses 'Maths'. The US uses 'Math'. "If i've done my mathematics correctly..." or "If I've done my mathematic correctly". It kinda makes sense though, as he used multiple calculations, so used the plural (Mathematics=Maths). If you wanted to get really picky, both are actually wrong and it should be 'Mathematica'.

    Benny Banger 3 months ago The problem is not that the "cheap panels" are always nasty - you proved some are not - but the expensive panels can be just really cheap panels with a brand name attached and huge mark up. It's not that I don't trust the cheapies - you get what you get, but I don't trust the pricey ones - maybe it is a good one, maybe its not, yet you pay through the nose - you can't judge by the price. What a great review Michael! Please keep them coming. Your enthusiasm and fun spirit is such a change from the others (not saying others aren't good, just not as good as yours!)

Then someone said to raise it to $1500 and I sold it 2 days later for $1200. Just shows if something has a big price tag on it, people think it's better.
  • Hugh Leyton
    Hugh Leyton 3 months ago The best, and simple way to check the best Solar Panels is to measure the Open Circuit Voltage and the Short Circuit Current. Now take 80% of the Open Circuit Voltage multiplied by 90% of the Short Circuit Current, to give you the POWER The Open circuit Voltage should be fairly consistent regardless of how much sun or cloud there is. It is the Short Circuit Current that is the all important one that varies with how bright the Sun is. Good panels will give you more Short Circuit Current under identical conditions. Divide your power by the surface area of your solar panel in square meters, to get the Power per sq.meter. These should be around 16% to 18% efficiency from the actual Sun's energy on your panel. Full Sun on a cloud free dark blue sky around midday should deliver about 1,000W. So at 17% efficient, you could get 170W. Quality may then simply come down to how long they will last. Solar Panels can last 50 years or more, if looked after and protected from damage.

  • bill
    bill 3 months ago @Mikey Gee Just got to love those 1000 watt led that pull 105 watts from the wall. By the way, Quantum Boards penetrate much better than Plurple leds.
  • Mikey Gee
    Mikey Gee 3 months ago (edited) @bill you have to know how LEDS are rated to understand that wattage rating. It's not like with hps, mh etc, lights. Wattage is useless anyway. It's all about the micromoles, light distribution, etc. Blurple lights are already phasing out in favor of full spectrum even on the cheap ones. I do hear quantum is good, but if you're just a hobbyist grower you don't need to spend hundreds or thousands of dollars to get good returns
  • bill
    bill 3 months ago @Mikey Gee Micky I understand all that. I was making a joke about those plurple lights that claim they are 1000 or 2000 watts (and sell for a couple of hundred dollars) but can barely support one plant. Besides QB's penetrate better than plurple anyway.

  • bill
    bill 3 months ago @Mikey Gee Atreum is about to take preorders for QB strips: "Comes in 4-ft and 2-ft versions (1154mm and 594mm, to be exact) 4-ft version is rated at 120W (2.3A @ 52V), 2-ft version is 60W (1.15A @ 52V). These are matched for the Meanwell HLG-120H-54 and HLG-60H-54, respectively. The spectrum is 4000K + 660nm deep-red supplementation. CRI is 90+. The light output is gorgeous! Custom-extruded heatsink, matched to the strip. By custom, I mean we did the thermal analysis, designed the profile, made an extrusion die, and machined in all mounting holes. We also include brackets to hang each strip individually, or mount to a rail. Comes pre-assembled with a 2-foot pigtail, ready to plug and play Pre-orders opening soon"

  • Trumpet Player
    Trumpet Player 3 months ago @Seek Adventure Another thing to look for, is also how much the performance deteriorates over time, for a cheap v.s. a more expensive panel. A certain percentage over time. That can be quite difficult to evaluate.
  • Allen Blum
    Allen Blum 3 months ago @Benny Banger Well put. Before I buy, I try to find several independent opinions. On Amazon, I look at the ratio of 4-5 star reviews to 1-2 stars. I look at the low ratings to see if there is a common thread Something to keep in mind is that many reviews only cover features, performance, and initial quality. Medium- and long-term Reliability info is much harder to find.
