Product Description

Tired of all the noise and smell from your diesel generator? The Instapark SP-50W solar panel offers you a quiet, clean while carbon-free alternative. Capable of converting virtually unlimited solar energy into clean, green, most importantly, free electricity, this solar panel is made of high efficiency mono-crystalline solar cells embedded in transparent vinyl acetate behind tempered glass with heavy back sheet ensuring maintenance free performance. Unlike amorphous solar panels, which only last about 5-7 years of continuous use, mono-crystalline solar panels can still retain over 80% of efficiency even after 25 years of continuous use. Also, the mono-crystalline panels are much more efficient and thus smaller in size while producing higher wattage.

This solar panel is designed and engineered to primarily charge 12-Volt batteries, which store and provide usable power when needed, ideal for powering your RVs, ATV, marine boats and electronic equipments. Other than recreational applications, solar power can also help lower your energy bills by reducing your dependence on the main electrical grid and provide back-up power during power outages.

Watch this video if you need help with solar power setup. This will help what you need to buy, guaranteed!Sunforce 60031 10 Amp Digital Charge Controller] ][[ASIN:B001TE0IMG Cobra CPI 880 800 Watt 12 Volt DC to 120 Volt AC Power Inverter with 5 Volt USB output Instapark® 50W Mono-crystalline Solar Panel These are the items I bought for my solar power setup plus everstart marine battery 27DC-6 from walmart.

P.S. Pure sine wave inverters are also 3x more expensive than modified sine wave inverters. Modified sine wave inverters can do most of the jobs pure sine wave inverters do. I didn't mention this in the video but most of the times, deep cycle and marine batteries have 2 rectangular caps, look in the video closely, you have to put distilled water or drinkable water(it's okay), and fill it up until about 1 inch below the opening of the holes. Check these water levels about once every 3 days(recommended). Just take the caps off to put the water in if needed. Also, charge controllers are heavily recommended if you use a solar panel greater than 10 to 15 watts. Mono-crystalliine and poly-crystalliine solar panels are recommended, amorphous panels are not recommended because they're not efficient as the other two types of panels and they generally last shorter than the other two. You can buy a smaller inverter, smaller controller, smaller battery,smaller panels or larger of them depending on your needs.

3.0 out of 5 stars Very nice panel, seems to work well., July 25, 2011

This panel works well. Even in a very overcast day, I still get good voltage and decent amperage from it.

The only downside, which is why I only gave it 3 starts, is that the factory cable did not have any connectors on it as the description mentioned. It simply had a cable with the ends slightly stripped back, and the penetrations into the J-Box can not make a good seal with the factory cable. This is not a big deal for me as I was planning on making my own wiring harness anyway.

Yesterday we hooked up our solar panel. It works great!! We hooked it up with a 10 Amp charge controller. This panel is keeping our 5th wheel powered up great. It charges even when the sun is not directly on it which is nice. We hooked it all into our electrical system and it started charging immediately. This panel does NOT come with the connecters as shown in the pictures so be ready to crimp your wires. Also ours did come with the positive and negative wires marked. If we add another panel then we will get a 30 Amp charge controller for a better charge to our batteries. I am glad that we had a friend that used to work in the solar industry explain that to us. But for now we are just going to add another battery and we should be good. Maybe next month we will add another panel. This seems to be built well, nice and heavy construction. Not a wimpy piece of junk. Great value for the price. If I had it to do over again I would order this panel. It showed up in perfect condition. Shipping was quick and it was packed nicely with styrofoam padding all of the way around it. No problems there.
