This product works great it provides me with enough power to keep in touch with the outside world.

80 Watts/4.67 Amps = 17 volts.
Be sure to size your system appropriately to minimize voltage drop to your inverter.
Sunforce isnt the cheapest, but still a good price and a nice, solid product with a 25-year warranty.
Note: GET A SOLAR SURVEY – you might not qualify for any tax rebates if you dont get one!
Also do the math yourself. If you live on the 43rd paralell and get 4.4 sun hours per day average, do NOT place these at 43 degrees! Tilt them closer to the SUMMER sun angle. You’ll get more sun in summer and less in winter, but you arent getting much in winter anyways! You’ll get more yearly output (or get a tracker and not do any math)
The technology is getting better; cheaper manufacturing processes and better spectrum band as well as improvements leading to higher efficiencies. If you want better stuff, I dont know how “long” you should wait. It can only get so good, the potput isnt going to duble or anything. Laws of physics

As my first venture into solar energy this has been a nice panel. I’ve had it about a month. I paired it with a “Xantrex Technologies 802-1500 XPower Powerpack 1,500-Watt Portable Backup Power System” and a “Sunforce 60032 30 Amp Digital Charge Controller”. The panel is 12 volt, 4.6 amps though at this point I’m seeing up to 13.6 volts and 5 amps. I suspect over time as the panel weakens it will be more toward the 12 volt, 4.6 amp. The panel was simple to hook up and came with what was needed. I did go purchase new wire as I needed more distance for where I mounted it. I’m able to charge the battery from dead to full in 2 days. If I were to rotate the panel through the day I feel I could fully charge in 1 day.
Nice for backup charging and learning. For any real application you would need a ton of these though.

Took the panel to Death Valley for a few days to charge my trailer battery and while I ran laptop and iPod stereo for hours during the night, it quickly recharged the battery the next morning. Built a solid stand/rack to keep it upright using pvc pipe that’s easy to disassemble, secure and lock. At 80 watts, it’s just one panel where some 65watt units have 3 panels.

I purchased 4 of these solar panels. They were easy to setup, and have been working just fine for the last month. They have been operating at near the specified 80 watts each which is pretty good for December in Utah.
