Sunforce 50048 60W Solar Charging Kit Review

I purchased two of these kits (8 panels) and mounted them on the top of my RV. I have had them on the top of my RV now for approximately 8 months.

When I received the units, I tested each of them for the open voltage measurement noted in the instructions with a digital meter and found each to be producing 21 volts unloaded. Encouraged that the panels were working properly, I went ahead and took the time and expense to mount them to the top of my RV.

After 8 months, here's what I found:

First of all, the 15 watt, 1 amp peak output rating that Sunforce advertises is not correct. The peak output rating for each of these panels should have been advertised at approximately 750 milliamps per panel. The total peak output that one could typically expect from the 4 panels in this kit would be around 3 amps. 3 amps under perfect conditions.

I have noticed that the boards are extremely prone to large drops (upwards of 45%) in current output when they begin to heat up. In other words, the boards are VERY intolerant to high temperatures. But even under perfect conditions, the 8 panels that I have mounted on my RV only produced 6 amps, and I am in Hawaii.

Another problem: The boards shut down in lower light situations. In other words, early morning and later afternoon lighting, significant cloud cover, or other low light situation will be cause for either a total shut down of output, or the boards will be very poor performers - in the low milliamps for 8 panels in parallel.

Within a very short period of time (about 4 months) the output from the panels gradually decreased by nearly 50%. And right now I am getting about 40% of the advertised peak output in perfect conditions.

The plastic construction is very cheap, in my opinion, and I am now worried that the plastic may break away around the screws that hold down the panels and fly off the vehicle. Needless to say, I am removing the panels.

I'm out some money, a lot of time and effort, but I've learned a lot about solar panel technology over the past 8 months.

For just a few bucks more, I will purchase a decent monocrystilline, 36 cell panel that will far and away outproduce the 8 panels that I have on my RV now, and take up far less space and be much safer on top of the vehicle.

Don't waste your time or money on this kind of solar panel technology. You will be very sorry.
