Panel works well in most condutions. Even when cloudy it still charges the battery. Using this panel to keep a 12v 9amp battery topped up. The battery is used via a timer to power a 12v 2bar water pump that irrigates my allotment via a soaker hose system.
Really pleased with this. Seems really good quality and works really well. My only minor complaint is that the crocodile clip leads are far too short. They are in a nicely insulated lead until they separate out a few inches from the end. They are not even long enough to reach the poles on a standard leisure battery which is surely what most people will be connecting it to. I had to cut back the insulation to make them longer which is a shame. They could also do with being larger as they don’t open wide enough to fit round the battery poles. Other than that it’s a great product.
I found the 25W solar kit so good I bought it twice. The service and communication were exceptional, with next day delivery.
When I need another solar panel I would not hesitate to buy from Eco Worthy.
I currently have this setup on my daughter’s Wendy house with an 8ah LifePo battery.
Running various bits through the charge controller I have lights and a 12v USB socket to charge tablets etc.
So far I haven’t been able to get my battery below the 50% led indicator and it will recharge with in an April cloudy day in the UK quite easily. Sub 100 you can get a nice little kit to run some basic off grid stuff, ideal if your looking for a alloment Shed, Garage or other garden building.
This is the third of these I have bought and they are good for the job, they may not be the cheapest but looking at comments for others they seem to be better value for the money. All three panels are doing the job required of them.
Otherwise I am happy so far.
I bought this for my allotment shed to keep a leisure battery charged. Fairly robust panel and whilst the charge controller is pretty cheaply made there is nothing wrong with it at all. It does a great job in direct sunlight and by the end of any bright day I’m hitting 13v no problem. On overcast days it doesn’t do such a great job but I live in South Wales and it has kept two 3w lights going for 4-5 hours a day through all of December without any issues. So I’m happy. Would recommend for sure.
Got 3 of these panels now, they all work great, the charger however is not so good, My batteries were at 15.2 volts with this and the output is the same , surely it should regulate the output to 12v ish. Was going to buy another to replace my blue cheap Chinese ones but this seems worse
Charging up boat batteries very effectively, about 12 watts being seen on a sunny day from behind the windscreen and not perfectly aligned to the sun according to the battery monitor.
I had the solar panel (10W) at ~15:00 April UK (south Wales) under full sunshine and the panel was producing 21.1V and 0.61amps. My simple calculatations (voltage x amps) suggest that this panel exceeds its 10W and was producing ~12.9W. Of course this is short circuit with a mutimeter and not under load, but it is rated as 0.61amps (short circuit) and I was getting this in April. Under somewhat cloudy weather it was producing ~0.4amps, quite good considering the clouds and that it is April in the UK. I have not yet fully tested it, as it draws a bit of current while the solar panel does not get sunshine, but at ~32mA standby current for 10h during a night it would draw 320mA, which is nothing.
The charge controller works as expected, but remember to connect the battery first and then the solar panel. Pretty simple to setup up with a sealed lead acid car battery. The default of the charge controller is sealed lead acid battery, but if that needs changing, simply hold the on/off button for 5s and 3 settings can be selected, sealed, gel and flooded.
Overall more than happy with this purchase of a 10W solar panel and charger controller kit for 26.
One slightly negative thing is that the PV and Load led lights are a bit too bright, they could have toned them down a bit. Also, there is no way to change the load light coming on (or load being on) when the device is disconnected. For the price these are really minor things.
Edit: After a bit of testing it is pretty good solar panel. Even in April (South Wales), 11am, behind a double-glazed window my power meter was showing 4.5W and 300mA (see photo of the 4.5W produced under load). It is unevitable that the double-glazed window will reduce the power output, so pretty happy with this purchase. In addition, the charge controller will go into a float mode of ~13.7V after the bulk charge of 14.4V. Thus, it will not over-charge your car battery. I also put the solar panel outside (end of April south Wales; 13h) and my wattage meter was showing 8W and 584mA generated under load (12V car battery). So, the specs are spot on.
I’ve installed on my boat to keep the cranking battery charged up. I have a Chargemetrix device installed so can remotely monitor the battery condition, and I can see the effect of the solar panel straight away. Superb bit of kit.
The charge light came on a 07:36 on cold damp morning, but taking measurements I found that in fact the battery was discharging at 3.7mA, with the PV panel switched off the discharge reduced to 2.4mA. This means 1) the charge LED only indicates that there is a voltage generated by the PV panel and does not necessarily mean the battery is actually charging, and 2) the battery will lose charge overnight or in overcast conditions if left connected to the controller.
Connecting the panel to the battery via a Schottky diode on an overcast day generated about 10mA in the morning, increasing towards midday and then back down again in the evening. Much better on a sunny day as you’d expect.
The implication is that if you leave the controller permanently connect to a battery during the winter, you could end up with a flat battery. To keep a battery in condition over winter I would go for a panel with crocodile clips and no controller.
EDIT – from experiments it would appear that this unit does NOT have a blocking diode, bear this in mind if you want to connect it directly to a battery or in parallel with other panels.
Edit – swift response from seller, the controller needs to be connected to a Charged battery initially, which I didn’t find in the manual.
Excellent product, used for charging car battery while my car is in storage for 6 months, as it is a summer use only car. Good response to a few queries on its use from suppliers!
