Hyundai Solar Panels?

[dgsail]

We are new boat owners looking to install solar panels .... just got a quote on a good deal on Hyundai Solar Panels MG Series... wondering if anyone has any info/reviews/experience regarding these panels?

Looking at the specifications for the Hyundai solar panels, it seems that their efficiency is in the 14 to 16 percent range. Given that space and weight is often an issue on a boat, I would consider panels with a higher efficiency.

I personally use Sunpower (SPR-90) panels and I am very pleased with them. They now make them over 20 % efficient. See here: Monocrystalline Solar Panels | Cleversolar UK

They only make them up to 135 watts, but I know that Sanyo makes large highly efficient panels too (HIT series). I have no personal experience with them, though.

Welcome to the forum
I have not heard of them before, but their specifications look OK for a 12v (not 24v) system with a MPPT regulator.
The efficiency as Bjarnek points is a bit less than the best, but about typical for many panels.
The number of bypass diodes is a bit low, which will make them a bit less shade tolerant than some. There have been some concerns with many companies not honouring the warranty in marine systems, but frankly they so rarely fail I do not think its much of an issue.

The most important thing is to get the most watts for the space you have at a good price.

The two most powerfull and lightest panels for there size are Sunpower 240 watt 31”X61” and Sanyo 235 watt 31x 62 both weight 33 lbs.
SunPower also makes a 337 watt 41 x 61 panel.

1) Buy panels first to fit your mounting location.
2) Mount your panels
3) Buy a MPPT(maximum power point tracking) controller to match you panels output
4) Mount the controller as close to your house batteries as possible
5) Buy the 10 gauge wire with the MC4 connectors to run from panel to controller
6) Wire the whole system together putting a wrap of red tap on all + leads will help.
7) Check your wiring
8) Check your wiring again
9) Start your system up
