Sunforce kits are easy to set up and operate.
The Sunforce 50048 60-Watt Solar Charging Kit lets you harness the power of the sun, the most powerful and plentiful source of energy available to us. This inexhaustible supply of power is freely available wherever the sun shines, and gives users the freedom to power their homes, RVs, boats, batteries, and electronic equipment far from civilization or right in town. Solar power can help cut your energy bills by reducing your dependence on the main electrical grid, and can also provide back-up power during outages. Unlike nuclear and fossil fuels, solar power systems are clean and pollution-free, and they require very little maintenance to operate.
Sunforce Solar Panels are effective in areas of both high and lower
sun exposure, making them ideal for use in the United States.
The Sunforce 50048 60-Watt Solar Charging Kit has everything you need to start generating power. It includes four (4) 15-Watt amorphous solar panels with durable mounting frames, a 200-Watt modified sine wave power inverter, a 7-Amp solar charge controller, and a wiring kit with accessories for easy installation.
With built-in blocking diode technology, this solar charging kit is designed to protect against battery discharge at night. You can also use this kit to maintain the charge on any 12-Volt battery for clean, silent operation of various electronics, such as deer feeders and landscaping pumps. You can also use this kit to maintain the charge on any 12-Volt battery for clean, silent operation of various electronics, such as deer feeders and landscaping pumps and is a great choice for automobiles, recreational vehicles, tractors, all-terrain vehicles, boats, electric fences, telemetry and more.
About Amorphous Solar Power
Amorphous solar panels are created by spraying silicon on to glass in very thin layers, and are commonly known as thin film solar panels. This process allows them to be better at generating electricity in all lighting conditions, including cloudy or shady environments. Sunforce amorphous solar panels are weatherproof and suitable for outdoor use. They have a maximum operating temperature range of -40 to 176-degrees Fahrenheit, require virtually no maintenance, and are also effective on cloudy days. They can even withstand impacts from one-inch hailstones at 50 miles-per-hour.
Solar panels convert sunlight into an electric current, they do not store power. Sunforce Solar Charging Kits are primarily used to recharge 12-Volt batteries (not included), which store and provide usable power. The included 200-Watt power inverter allows you to use traditional 110-Volt appliances with this system. The included Sunforce 7-Amp Solar Charge Controller must be installed to prevent any connected batteries from overcharging. Once fully charged, it is normal for the charge controller LED to turn off and on as the battery voltage fluctuates from the discharge/recharge cycle.

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.Read more ›
Meanwhile Amazon got their hands on some obsolete & discontinued Sharp panels (12.5% efficiency vs the new 13.1% efficiency) - if you are serious about needing lots of solar power in a small space, this is a big kit - you can view it here: Sunforce 39126 246-Watt High-Efficiency Polycrystalline Solar Power Kit
My only concern about the kit is that due to the new panels being higher efficiency means it will be difficult to match panels if you find you still need more power later on. The other con on that system is it's price -- $1300+ but you get the wattage, along with a cheap charge controller and inverter, both of which could be upgraded for better system performance. It's just another solar system to consider in the $5/watt or less pricepoint for DIYers.
Update 9-18-2008 - Still going strong. I am very pleased with the summer power output of these panels. I wash them with a hose 1x/mo to keep the output current up.Read more ›
Like most manufacturer's specs, the 60 watt claim is hard to realize. The panels' current output is about 3.2 amps under bright sun, which yields only about 45 watts into a 12 volt gel cell battery at 14.2 volts. The panels can output about 20 volts which would indeed yield 60 watts, but not while connected with the included charge controller. A MPPT controller would achieve 60 watts, however.
The included controller is acceptable in that it works as advertised. One good thing about it is that it does not shunt the panels when the battery is charged, it actually opens the circuit, which means the excess panel output would be available for other uses. I intend to build another device for charging another set of batteries after the primary set is charged.
The included inverter works, but I did not use it in the system. Instead, I'll just keep it around for a portable inverter.
Also, I did not use the PVC pipe stand included with the system, instead mounting the panels directly to the roof.
The kit did include a variety of connectors allowing use with cigarette lighter plugs and jacks, alligator clips, and hardwire, but the charge controller is only usable if hardwired. I strongly recommend the charge controller be used, as the panels can easily overcharge most any 12 volt battery if a charge controller is not wired in.
