## Customer Reviews

### ⭐⭐⭐⭐⭐ My first time with PV
*by G***E on April 14, 2013*

I ordered this 50 watt solar panel to charge my RV batteries while the RV sat in storage and to use when we dry camp (camping with out power or hook ups). At present i have only had the opurtunity to use this unit to maintiane the two six volt batteries charge and it is doing a great job. I originally ordered this with the HQRP solar charger (the charger was damaged on shipment and was returned) I have sinced purchased another charger ( a sunforce 10 amp ) and had a chance to bench test the system with a automotive style battery. The instructions say that you should start the system with a charged battery (these charge controlers do not have the capacity to charge up a dead battery, too many amps to draw, and they are designed to shut down to protect themselves under heavy loads) which I did. I attached a a/c-d/c converter, a volt meter and a in-line amp meter to the battery to observe the performance and operation of these devices. I was very impressed with the performance. I put a 4 amp load onto the converter/battery and on a clear sunny day this solar panel maintained the battery charge and ran the 4 amp load for about two hours till the sun light was blocked by light clouds, only until then I saw the battery start to discharge. I allowed the battery to discharge till the voltage fell into the low 11 volts. I disconected the 4 amp load and allowed the solar cell to charge the battery only and in about an hour the battery was charged and above 12.8 volts. Very good performance for northern california.I will re-post when I do dry camp. I will be able to give a better idea of how this system performs under a real working load condition over time.Update, Nov, 2013. I have had this panel on my RV and it has kept all the batteries charged and in good order. It has been in the weather, good and bad, hot and cold and has held up very well. I have also installed an isolated parallel circuit for this system to charge the RV's 12 volt engine battery. I have seen it written that you should not mix 6 volts and 12 volt batteries (I have two 6 volt batteries set up in series to produce 12 volt) and charge both on the same circuit. As I said I have installed isolation diodes/relays and paralleled the charging circuits and made sure that the controller was sized correctly and it appears to be charging all the batteries fine. BTW, the isolation relays are to disconnect the solar charging circuit from the engine battery when the ignition is turned on. This is to keep the engines alternator charging circuit from back feeding voltage into the solar circuit (even though diodes will do this job alone, I like my redundancy).Update, July 2016, I have had these same products on my RV since I purchased it. I also have the same batteries from the same install date. That means that this system has not allowed the batteries to either over charge and cook the cells in the batteries nor under charge and allow the batteries to fail. I have also dry camped, several times, for over a week and had to run my two 12 volt heaters all night and even though I did see a large voltage drop on the coach batteries by the morning. During the day, the single solar cell charged both batteries up fully for several repeated nights running of my heaters (during the day I run a small gas indoor heater to keep warm but to be safe, I don't like to sleep with the idea that a heater is burning my oxygen and producing carbon monoxide). The controller does "condition" the batteries as described which dis-allows sulfates from developing but I did notice that this controller does cause the water level in the battery to drop over a few weeks so I do need to make sure I visit the batteries, in the off season while the RV sits, and keep an eye on the battery water level. So far I have been very impressed with my little set up and I have not seen an issue with mixing 6 volt and 12 volt batteries on the same charging system (see mention above in last update). I am currently ordering three more of these solar cells and will be installing a bank of four 6 volt batteries and a 12 volt to 120 volt converter so I don't have to run my noisy/smelly generator to power my tv and lights at night (and save my gas for traveling).

### ⭐⭐⭐ Not a full 50
*by F***T on August 1, 2014*

I could only get about 30 watts out of these in the middle of summer in the central valley of california where it was 107 degrees outside and clear and sunny although there was some smoke in the air it appeared clear.

### ⭐⭐⭐⭐ Frugal spender
*by A***R on April 20, 2012*

Mounted this on a flat roof on my motor home. The measured current and power is way below the advertised 50W. The power varies during the time of day as expected. The maximum power registered about noon is about 29 watts. I paid $120 for this panel and was thinking of adding another panel but found the price has increased to $145. The panel is not worth that price of over $5/watt on a flat roof. Even if I could tilt the panel for max power and assume the 50 watt spec is accurate then it is still $3/watt. The quality of this panel is excellent. I have used this for 1.5 years and it is good for charging my batteries.
