How do the Solar Panels work?
The solar power is the conversion of energy from sunlight into electricity. This is made easier with CIGS Solar Cells, using direct and indirect solar power. CIGS solar panels are a step forward in Photovoltaic systems using solar panels on the go, converting sunlight directly into electric power. Conventional solar panels are restricted to the use of solar power outside your home due to its weight and inefficiency. For higher efficiency in conventional solar panels, there is need for micro inverter. With CIGS Solar Panel, there is no need for inverter and it can be used even with a damaged section and within overcast conditions.
Solar Panel Technologies Comparison
Monocrystalline Silicon Solar Cells
Mono-Si are called single crystalline silicon, are quote easily recognizable from its even coloring and rigid uniform look. Mono-Si are made out of silicon ingots which are in cylindrical shape. To optimize performance and lower costs of a single monocrytalline solar cell, four sides are cut out of cylindrical ingots to make silicon wafers.
The disadvantage is that it can be heavy and has to be cleared regularly to keep the efficiency of the solar cells even.
Polycrystalline Silicon Solar Cells
P-Si (Polycrystalline Silicon) are one of the first to be introduced to the market. Since then, many solar cells have showed huge more potential than its predecessors.
Copper Indium Gallium Selenide (CIGS) Solar Cells
Compared to the other thin-film technologies, CIGS solar cells have showed the most potential in terms of efficiency. Contains less amounts of the toxic material cadmium. Before the commercial production of flexible CIGS Solar panels, it was used for military use only due to its roll-able and easy to carry features. This is most likely to be the future for Solar cells.
Pros and Cons
|Highest Efficiency rate (15-20%)||p-Si||Showed the most potential when compared with other solar panels|
|Require Less Space to install||Simpler than Mono and cost less||Less amount of toxic material is found in CIGS Solar Panels|
|Longest life time||Lower heat tolerance than monocrytalline solar panels (meaning perform slightly worse than mono in high temperatures)||Efficiency is a tradeoff between its flexibility and cost. (10-12)%|
|Performance rate similar to Poly||13-16% efficient||Highest energy yield in low light and over cast conditions|
|Tend to perform at low-light conditions||Covers Large area to output same power as mono.||Tend to perform with damage sections|
|Very Expensive||Enormous Potential in the future|
|Dirt or snow, the entire circuit can break down||Military Grade|
|Not Waterproof||Not Waterproof||Less Toxic material has attracted a huge sale (low environmental impact and sustainability)|
|Reasonably Heavy||Heavier than CIGS||Lightweight and Durable|
|Uses more toxic cadmium material||Use of cadmium material (Toxic)||Waterproof|
|Highest efficiency of thin film PV technologies|
|Flexible material offers low weight per area (kg/m2) and low weight power generated (kg/W)|
