100 - 450watt 24v 36v mono and poly solar panel half cell
Product description
Solar panels (also known as "PV panels") are used to convert light
from the sun, which is composed of particles of energy called
"photons", into electricity that can be used to power electrical
loads. Simply put, a solar panel works by allowing photons, or
particles of light, to knock electrons free from atoms, generating
a flow of electricity. Solar panels actually comprise many, smaller
units called photovoltaic cells. (Photovoltaic simply means they
convert sunlight into electricity.)

Main features
1. Higher Yield Due to Better Shading Response. Half Cell Module comprises two separated and identical solalr cell
arrays, which means the ordinary strings of cells are cut into
halves, and these shorter strings compose which has separated
current paths. When a module is shaded, only one side shaded
array's current will be impacted, while the other array will still
be functionally producing power. Under this circumstance, when a
module is shaded, the affected working areas of Blade will be 50%
less. By cutting solar cell into halves, the internal power loss
will be lower and hot spot effect will also be reduced.
2. Less Mismatch Loss. Instead of 6 internal strings of cells, half cell module has 2*6
shorter ones. This design effectively deals with the mismatch
happened between cells caused by shadow, out of sync performance
degradation, etc.
