What is the difference between amorphous Polycrystalline and Polycrystalline panels?
Amorphous solar panels are created by spraying silicon on to glass in very thin layers (TCO), 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.

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.

General Characteristics:
All three products are environment-friendly, generate free and renewable power. The panels convert sunlight into electronic current, they do not store power directly. If you want to store electronic power, please use lead-acid automotive batteries, deep-cycle (traction type) batteries, gel-cell batteries, or heavy-duty (stationary type) batteries. Deep-cycle marine batteries are recommended to use with these panels. These panels need no maintenance one installed. They can be integrated together with compatible products to generate more power. The panels are under 25 years warranty but not the compatible devices.
Differences
Sunforce 50044 has built-in blocking diode, while Sunforce 39810, Sunforce 39110 need a compatible charge controller, which is sold separately from the main products. Other accessories are free with the main products.
Sunforce 50044 adopts amorphous design while Sunforce 39810, Sunforce 39110 adopts Polycrystalline design. The former is more cost-efficient but has a little lower conversion coefficient.
Sunforce 50044 can work under all kinds of weather conditions whether it is sunny, cloudy, or even very weak light conditions. While Sunforce 39810, Sunforce 39110 are also weather-proof but less efficient with weak light conditions.
Sunforce 50044 needs pvc support while Sunforce 39810, Sunforce 39110 don’t need.
Sunforce 39110 cannot be shipped to APO/FPO, Hawaii, Alaska, or Puerto Rico while the other 2 products can be shipping all over the states.

The factors affect solar system design:
1.   Where the system will be located and the solar radiation conditions at the spot;
2.   The load power size;
3.   Output voltage, DC or AC;
4.   System function time each day;
5.   How many days to be supported if there is no sunlight at all;
6.   Load conditions, pure resistive, capacitive, or inductive, starting current.

Solar Panel Introduction
Solar energy panels are photovoltaic (PV) devices to produce power from sunlight, the ultimate source of energy.

Solar energy is harnessed using photovoltaic cells. Groups of photovoltaic cells are known as solar modules. There are a range of products using single crystal solar cells producing 6 to 123 watts of power. The modules can be adapted to off-grid or on-grid power generation needs. The modules offer a 25-year warranty.

The modules based on crystalline silicon are one of the most efficient available on a commercial basis. The modules are formed by a series of cells wired together and are available in complete packages for residential, commercial, and industrial purposes.
Using solar energy bestows one with up to a thirty percent tax credit from the federal government. More than that, solar power does not release harmful emissions, whereas most other forms of power release effluents leading to global warming, acid rains, and smog. Backup batteries ensure the unlimited supply of power even in the absence of sunlight.

Solar energy panels can use the sun’s energy to heat water for sanitary use at home or for pools and hot tubs. PV panels, on the other hand, convert light into electricity. Most commonly, these panels are placed on the roof. The power generated by PV panels is transmitted to a battery for storage. Household power needs are drawn from this storage.
