Solar Panels

 

 

Solar panels are made of photovoltaic cells that consist of a positive and a negative film of silicon placed under a thin slice of glass. As the photons of the sunlight beat down upon these cells, they knock the electrons off the silicon. The negatively-charged free electrons are preferentially attracted to one side of the silicon cell, which creates an electric voltage that can be collected and channeled. This current is gathered by wiring the individual solar panels together in series to form a solar photovoltaic array. Depending on the size of the installation, multiple strings of solar photovoltaic array cables terminate in one electrical box, called a fused array combiner. The electricity produced at this stage is DC (direct current) and must be converted to AC (alternating current) suitable for use in your home or business.

 

TYPES OF SOLAR PANELS

Mono Crystalline Solar Panels

Advantages:
-- Made out of the highest-grade silicon hence have better efficiency.
-- Efficient in low-light conditions areas. (Northern Areas).
-- Better life than polycrystalline due to high-grade silicon.
-- Monocrystalline solar panels tend to be more efficient in warm weather. Difference is small.
Disadvantages:
-- Higher costs than polycrystalline (5-10Rs per watt).

 

Poly Crystalline Solar Panels

Advantages:
-- Lower costs than monocrystalline solar panels.
-- Modern technology have made polycrystalline panels more efficient, close to monocrystalline.
Disadvantages:
-- Made out of lower silicon purity, hence have lower efficiency than monocrystalline solar panels.
-- Not efficient as monocrystalline solar panels in low-light conditions.
