Product Description
Amazon.com Product Description
The Sunforce 39810 80-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 homes, cabins, 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 80 Watts of clean, free power in all weather conditions.
Convenient Power That Helps You Save Money and Protect the Environment
The Sunforce 39810 80-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, cabins, batteries, appliances and electronic equipment far from civilization--or even 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.
Flexible Power for New or Existing Systems
The Sunforce 39810 80-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 80-Watts/4.67-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.
 Sunforce panels can be easily added to new or existing systems. |

QUICK UPDATE: Sunforce is selling obsolete Sharp 12% efficient panels no longer in production at 123W/panel, 2 panels to a kit with a junky inverter and charge controller.. See my review at Sunforce 39126 246-Watt High-Efficiency Polycrystalline Solar Power Kit but choose cautiosly as that product is from 2008 and is now obsolete which makes expansion of your system difficult due to the efficiency change.
---back to the review as it stood originally---
In evaluating solar panels (and systems of many panels) the typical pricepoint is $5.10/watt in high volume production. If you are finding better pricing than that something is wrong.
An example may be inefficient panels that use larger panels, causing massive panel size such that it is 4-8 times larger than this panel with the same output.
Other inefficiencies to watch out for are caused by voltages that are not useful. You could, for example, have a panel that output 500V at 1/10 A for 50W sold for $250 - looks good financially but very few charge controllers go much over 250 volts (and many dont make 250 volts - some are 12 or 48 volt systems). So that panel is not much use
This panel is in the sweet spot - enough power to be useful (80W/3 is a simple approximation for what useful power you can get with a battery all day long - about 25W or so given inefficiences. So theoretically it could support a 25W load 24x7 with an 8 hour day of sun.
The last inefficiencies to watch out for are panels that need heavy sun before they produce any output. Some panels produce usable (1-2 amps) output with just ambient scattered light such as a foggy day, while others give near zero output unless the sunlight strikes them head on. This panel design gives output whenever there is light, which is good. More light is always better, but it could be worse.
So to sum it up - there are no pitfalls here. It passes all the checks for pricing and performance. We load tested a string of 12 of these for a customer to profile their output to help decide if a rotator would help and it showed that very little gain would come from the expense of an automatic rotation system due to the panel's efficiency at many angles. With 12 panels we produced 1KW for 8 hours with taper up and down on both sides.
Best of all this can be used in series strings for grid tie systems or with battery maintainers

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.

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.

Great panel for small scale 12 volt systems
This is a very high quality panel by sharp. Provides good power even in the Northwest overcast days. I plan to buy more.

Great Panel - packed poorly
The panel is great - built very solid, as well.
One thing I did not care for: it was packed poorly. An extra layer of heavy cardboard on the outside of the box would be good. Read more
