Product Description |
The Sunforce 39110 123-Watt High-Efficiency Polycrystalline Solar Panel Module will give you several more reasons to love the sun. It provides the power you need, while helping you save money and protect the environment. This panel is ideal for cabins, recreational vehicles, remote power, back-up power, and 12-Volt battery charging. This panel comes with compatible wiring, accessories and a voltage tester to help you start producing up to 123 Watts of clean, free power in all weather conditions.
 Sunforce panels can be easily added to new or existing systems. | Convenient Power That Helps You Save Money and Protect the Environment
The Sunforce 39110 123-Watt High-Efficiency Polycrystalline Solar Panel Module 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.
View Larger | Flexible Power for New or Existing Systems
The Sunforce 39110 123-Watt High-Efficiency Polycrystalline Solar Panel Module is an ideal addition to both new and existing solar power systems. It comes with a voltage tester, wiring and mounting accessories to make installation easy. These solar panels can be used individually, or they can be connected together to boost power output.
Sunforce High-Efficiency Polycrystalline Solar Panels must be connected to a compatible charge controller (sold separately). The charge controller prevents the solar panel from overcharging and damaging connected batteries or electrical systems. It also prevents reverse current from sapping your battery strength at night. Sunforce High-Efficiency Polycrystalline Solar Panels can be connected in parallel for 12-Volt systems, or in series for 24- and 32-Volt applications. Please ensure that the components being used in your system are compatible with the individual and total output voltage of your solar panels.
About Polycrystalline Solar Power
Polycrystalline silicon is a material consisting of thin wafers that are cut from a silicon crystal which has grown in several directions. This advanced surface texturing process provides polycrystalline solar panels with a higher power output than amorphous panels of the same dimensions, and makes them more cost and space-effective. These individual wafers are assembled into panels that are covered by durable, weatherproof tempered glass. Thanks to their efficiency and durability, these solar panels require virtually no maintenance once installed. This solar panel has a maximum power output of 123-Watts/7.16-Amps.
Solar panels convert sunlight into an electric current; they do not actually store power. Sunforce Solar Power Panels are primarily used to recharge all types of 12-Volt batteries, including lead-acid automotive batteries, deep-cycle (traction type) batteries, gel-cell batteries, and heavy-duty (stationary type) batteries. When using these solar panels to run appliances on a regular basis, the use of deep-cycle marine batteries is recommended. This type of battery is designed to withstand the frequent charge and discharge cycles associated with solar panel use.

 New Camping Freedom |
| Review Date: April 25, 2009 |

| I purchased one of these about 8 months ago, along with the Sunforce digital 30-A controller and Duracell 800-w inverter to use on our motorhome when in campgrounds with no hookups or when boondocking. Works great! Really nice to have the extra freedom, and to not run the noisy/smelly generator. Provided plenty of battery charge for lighting, furnace fans, laptop, TV, etc for week long trip to Oregon outback in September. Have also used for numerous 3 - 5 day stays in California and Arizona in Feb - Apr. I built a portable/adjustable stand that takes only a few minutes to set up. |
Great panel, but check the voltage tester

| I purchased 4 of these for a small home solar system. I didn't have an optimal location to put them, so are shaded sometimes, but still put out a decent voltage even when the sun is setting and sunlight is not direct. They each come with an LED voltage tester, so I built 2 of them into the system to montior the panel & batteries. One caveat about those little testers though - the ones I got were defective. The upper LED will burn out quickly. This is because a zener diode was installed instead of the correct 910 ohm limiting resistor for this LED. I would recommend opening up the unit before using it and checking this. Actually I replaced all six 910 ohm resistors with 1.5k's to reduce the current draw to about 10 mA per LED, since they are in continuous use. Overall this is a great product so far. |
