DOKIO 160W 18V Solar Panel Kit Monocrystalline Portable Flexible Folding

I am going to give this a full 5 stars. I suggest you read the 1 star ratings about how much power people think these solar panels deliver also. At 2:50pm UK mid July (sun very high) the "160watt" solar panel was outputting (unplugged) 20.1v. When I connect an amphere meter across the output I got 6.9 amp. volts x current = wattage 20.1 x 6.9 = 138 watts This is where I think their 160 watt solar panel description comes from. On another day perhaps that would go a tiny bit higher. The current / amphere meter doesn't lie. Nor does the volt meter. One thing that I don't know is how much the voltage drops under load because I cant measure both at the same time BUT, the voltage will drop - this is important. Connecting the supplied box of tricks to the solar panel shows (see photos) and using its readings (they wont be wrong, perhaps not as accurate as a multimeter but not bad) what it showed was 14 volts and 6.2 amp = 86.8 watts. The problem between the 2 sets of readings is time and the fact tiny little clouds roll by which will have made a difference. The conditions were not perfect today for solar generation but certainly not bad - perhaps it is a 90 to 95% day (more heat would reduce efficiency but today may be a little hazy). All in all the first figure is calculatated wrong as the volts and amps are done separately but explains how they get their 160 watt figure and the 2nd figure I feel was a little down as conditions were slightly different. So lets be sensible and up the measured wattage by 10% to be fair. The solar panel was producing 86 to 95 watts today. Which isnt bad for an inexpensive flexible light weight solar/charger set. I think it could possibly go to 100 watt. Compared to my over twice the price solar panels this is OK if not quite good. My other panels get 90 to 105 watts and they are rated at 120 watt. Ignore the rating, are you happy with 80 to 90+ watts from this solar charger for £86? I am. The next issue is the output voltage to charge a battery. It was 14v and this wont be enough to properly charge a LifePO4 battery. In fact it was only charging my battery at 0.2a...but I wasnt expecting much because the battery is already fully charged. What I need to do is test the charging with a flat battery (I'll update this in a few days - today is 16th July). I want to see a charging voltage of 14.4 to 14.7v and most of that 6 amps, or at least 4 amps charging. This is very promising so far - a good solar panel. Many people complain about scratches and marks over the panels, yes I also have those marks (same as other peoples photos, the exact same scuff marks a year or 2 from when they did!). The marks do not effect the panels enough to worry about.

I was delighted that this solar panel survived the storms on Friday but also the caravan was on site over the bank holiday weekend where we had no electric hook up. I wired an extra leisure battery in parallel with this panel and fitted a 15amp fuse on the live connection from the panel to the battery and from Thursday night until about 8:00 pm on bank holiday Monday the batteries showed fully charged at the end. Without the solar panel I am sure the batteries would have been flat within a day or so. People charged their phones from the charge controller and power was used for 12volt lights, the electric toilet flush pump, the water pump and for igniting the gas cooker and gas fridge. I did not have time to fit the mains inverter I had bought which would have drawn a lot of current if it was used. In conclusion I would highly recommend this solar panel kit. This was my first time I had gone into solar panel generation and it has given me the confidence to install off grid solar for my home garden workshop where larger 36v solar panels will be used with a much larger charge controller. When folded up the solar panel was small enough to fit flat in the bottom of the caravan wardrobe keeping it safe when towing the caravan.

Really good piece of kit. Good value for money. Easy to use and charges the leisure battery well. Sadly the solar controller stopped working after a few weeks. Currently in talks with the seller to arrange a replacement, but been happy so far

Excellent price. Great performance even in Scotland where there's not much sun

Although it comes with a solar charge controller I am using this panel on holiday with a Victron mppt 75/10 which gets the most out of these 18 volt panels. So far, even in the dank weather we are having at the moment , the system is keeping my 100 ah lithium battery at optimum charge even with a fridge/freezer box permanently connected. Very much recommended! Just one thing though, I would have preferred some sort of attachment to the back of the panels to keep them propped up. As it is I leave them propped against the awning.

This is definitely not a 160w panel. My 120w panel was sitting next to it and was producing more power

Great product. Folds easily and has good output. Light portable and a good output of power.

Was disappointed with this item. It's very big, and cumbersome. Couldn't get any higher than 100w output even aimed directly at 33C sunlight. Folded size is also very large for transporting . Managed to get 160w from a different 200w solar panel, so it's not my device that is limited.

super panneau solaire assez grand simple à installer et à utiliser charge assez rapide rien à redire conforme à la description et aux photos ravie de mon achat très bon rapport qualité prix livraison rapide

tutto ok come da descrizione

The solar item works perfect, and easy to plagen to the car

This is an excellent bit of kit. Lightweight, portable and works really well.

Jättesmidig och tar ingen plats när den inte används, Ett jättebra köp i mitt tycke.
