ProtecttheEnvironment TheSunforce39810 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 tous. This inexhaustible supply of power is freely available wherever thesun shines, and gives users the freedom to power their homes, RVs,boats, batteries, and electronic equipment far from civilization or right intown. Solar power can help cut your energy bills by reducing your dependence on the main electrical grid, and can also provide back-uppower during outages. Unlike nuclear and fossil fuels, solar power systems are clean and pollution-free, and they require very littlemaintenance to operate.

systems. It comes with a voltage tester, wiring and mountingaccessories to make installation easy. These solar panels can be usedindividually, 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). Thecharge controller prevents the solar panel from overcharging anddamaging connected batteries or electrical systems. It also preventsreverse current from sapping your battery strength at night. SunforceHigh-Efficiency Polycrystalline Solar Panels can be connected in parallelfor 12-Volt systems, or in series for 24- and 32-Volt applications. Pleaseensure that the components being used in your system are compatiblewith 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 cutfrom a silicon crystal which has grown in several directions. Thisadvanced surface texturing process provides polycrystalline solar panelswith a higher power output than amorphous panels of the samedimensions, and makes them more cost and space-effective. Theseindividual 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. Thissolar panel has a maximum power output of 80-Watts/4.67-Amps.

Solar panels convert sunlight into an electric current; they do not actuallystore power. Sunforce Solar Power Panels are primarily used torecharge all types of 12-Volt batteries, including lead-acid automotivebatteries, deep-cycle (traction type) batteries, gel-cell batteries, andheavy-duty (stationary type) batteries. When using these solar panels torun appliances on a regular basis, the use of deep-cycle marinebatteries is recommended. This type of battery is designed to withstandthe frequent charge and discharge cycles associated with solar paneluse.

"Great Panel - packed poorly" 2010-02-27By R. Rothen 

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. The mounting- kit, cable

and free tester were just floating in the box. I bought two panels (2 separate

orders) - both times it was shipped in the same manner.

The panels would deserve 5 stars... but because of poor packing... onl y 3 stars. 

"Sunforce does the Job" 2010-02-07By John E. Miles (LAURINBURG, NC, US)

I've purchased the Sunforce 39810 80-watt solar panel, and completed the easy installation. I also purchased the 30 Amp controller. Both units are working as

advertised. The panel provides approx 4.7 amperes on a sunny day to recharge

my battery.

"An excellent bargain for either battery usage or grid tie - great sizetoo" 2010-02-05By HMMWV (santa clara, CA USA)

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 thanthat 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). Sothat 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 

"Off grid power" 2009-10-05By Wayne Shappy This product works great it provides me with enough power to keep in touch

with the outside world. 

"Rising force in the market" 2009-09-06

By V S (Milwaukee WI)

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 a25-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 ph ysics
