*A solar panel is a device that converts sunlight into electricity through the photovoltaic
(PV) effect, using photovoltaic cells, typically made of silicon.
*Sunlight strikes
the cells, creating an electric field that generates direct current (DC) electricity, which
is then converted to alternating current (AC) by an inverter for use in homes or businesses
or to be sent to the electric grid.
Types of solar pannel
| Solar Cell Type | Efficiency Rate | Advantages | Disadvantages |
|---|---|---|---|
| Monocrystalline Solar Panels (Mono-SI) | 20% | High efficiency rate; optimised for commercial use; high life-time value | Expensive |
| Polycrystalline Solar Panels (p-Si) | 15% | Lower price | Sensitive to high temperatures; lower lifespan & slightly less space efficiency |
| Thin-Film: Amorphous Silicon Solar Panels (A-SI) | 7-10% | Relatively low costs; easy to produce & flexible | shorter warranties & lifespan |
| Concentrated PV Cell (CVP) | 41% | Very high performance & efficiency rate | Solar tracker & cooling system needed (to reach high efficiency rate) |
The best type of solar panel
*Monocrystalline solar panels are the best type of solar panel in terms of efficiency. Their
ability to capture sunlight is higher than both polycrystalline panels and thin-film solar
panels. This is also why they are more expensive than cheap solar panels, which are almost
always made from polycrystalline.
*All black solar panels and most integrated solar
panels are monocrystalline in nature. Compared to the process for polycrystalline panels, the
structure of the silicon is aligned better in mono panels. As a result, they have higher
sunlight absorption rates.
1st Generation Solar Panels
Monocrystalline Solar Panels
*Monocrystalline solar panels are the best type of solar panel in terms of efficiency. Their ability to capture sunlight is higher than both polycrystalline panels and thin-film solar panels. This is also why they are more expensive than cheap solar panels, which are almost always made from polycrystalline.
Polycrystalline Solar Panels
*You can quickly distinguish these panels because this type of solar panels has squares, its angles are not cut, and it has a blue, speckled look. They are made by melting raw silicon, which is a faster and cheaper process than that used for monocrystalline panels.
2nd Generation Solar Panels
Thin-Film Solar Cells
*If you are looking for a less expensive option, you might want to look into thin-film. Thin-film solar panels are manufactured by placing one or more films of photovoltaic material (such as silicon, cadmium or copper) onto a substrate. These types of solar panels are the easiest to produce and economies of scale make them cheaper than the alternatives due to less material being needed for its production.
Amorphous Silicon Solar Cell
*Have you ever used a solar powered pocket calculator? Yes? Then you have definitely seen these types of solar panels before. The amorphous silicon solar cell is among the different types of solar panels, the one that is used mainly in such pocket calculators. This type of solar panel uses a triple layered technology, which is the best of the thin film variety.
In the world,the percentage of electricity generated from solar power has been as follows in recent years
*When looking at the graph below, it becomes easy to see the rapid increase in solar photovoltaic
power generation that has taken place during the last couple of years in the United Kingdom. Within
one year (2014-2015) solar PV power generation increased by almost 87%.
*Only few people are
aware of the different technologies that exist on the market for solar energy such as solar thermal
and solar water heating.
*Whereas these alternatives to the classical types of solar panels
are mainly used for heating water, the following paragraphs give a more detailed introduction to the
different types of solar panels that are used for generating green electricity. Several decades of
research, work, and development have lead to the wide range of different types of solar panels now
available on the market for solar panels
Benefits
*Renewable energy:Solar power is a renewable energy source, meaning it is replenished
naturally and will not run out.
*Reduced carbon footprintGenerating your own electricity
from the sun helps decrease reliance on fossil fuels and lowers carbon emissions.
*Lower
electricity bills:You can significantly reduce your monthly electricity costs by generating
your own power.
*Low maintenance:Solar panels require very little maintenance, with many
systems coming with long warranties
*Supports the economy:The solar industry supports jobs
and economic growth.
