There has been a legit spike in demand for renewable energy sources in several industrial markets in the last few years. One such source that helps us meet this demand is solar energy, and one of the most robust backbones of this resource is solar panels. Solar panels consist of solar cells, which are layers of silicon, boron, and phosphorus. These cells help in the accumulation of solar energy and its conversion into electricity. The process of electricity generation from a solar panel is known as the photovoltaic effect. If you want to explore the different types of solar panels, welcome to this comprehensive guide.
Monocrystalline Solar Panels
Monocrystalline solar panels are also known as single-crystal panels, and they are composed of a pure silicon crystal bifurcated into wafers. They often have a dark black color due to their silicon composition. If you are looking for a space-efficient and long-lasting solar panel, it is a perfect choice. Also, if you want your panels to stay clean 24/7, consider exploring an automatic solar panel cleaning system price and buy one which is cost-effective yet efficient.
Polycrystalline Solar Panels
These solar panels are composed of more than one silicon crystal where the fragments are melted and put in a square mold. In this way, we face less wastage of silicon, making this solar panel an affordable choice. However, one must consider the fact that silicon used isn’t pure before buying these solar panels. Because of lower silicon purity and construction are not efficient in converting sunlight into electricity and space management. Lastly, they offer you a lower heat tolerance, so avoid purchasing these panels if you have a high-temperature environment.
Passive Emitter and Rear Cell Panels
Are you looking for an improved version of traditional monocrystalline cells? If yes, then PERC panels will suit you the best! Passive emitter and rear cell panels have passivation attached to the back surface that helps enhance the effectiveness in the following ways:
- It increases the absorption of solar radiation.
- It stops the flow of electrons in the system and decreases the recombination of electrons.
- In traditional models, the wavelengths of over 1180 nanometers pass through the wafers without being absorbed. It causes the back sheet to turn hot and reduces the efficiency of the cell. But the passivation in modern PERC panels reflects these wavelengths, thus preventing the heat.
But remember that almost 30% of the energy is lost due to unclean panels. Therefore go on to check the automatic solar panel cleaning system price and get one for your panels.
Thin-Film Solar Panels
These solar panels have thin and flexible layers, and they are easier to install because each panel doesn’t need frame backing. One unique aspect of these panels is that they are available in multiple sizes. There are further three variations available for thin-film solar panel
- Cadmium Telluride
These cells offer you the lowest water requirement, carbon footprint, and energy payback. That is why you enjoy a cost-effective edge when you choose it. However, the cadmium used in such panels is toxic, and it poses difficulty in recycling and turns the process expensive.
- Amorphous Silicon
If you take a molecular look, these panels are not structured like mono and polycrystalline cells. Therefore they are shapeless at the molecular level. Amorphous silicon panels need a minimal amount of silicon, making them more budget-friendly, and they require less power like pocket calculators to operate.
- Copper Indium Gallium Selenide
It is a solar panel with a layer of copper, indium, gallium, and selenium on a glass. These layers help enhance the efficiency of power generation.
Consider the cost and environmental factors before deciding on your solar panel, and investing in a cleaning arrangement or kit is a great idea. The price of an automatic solar panel cleaning system differs from a manual cleaning kit. Therefore, looking at the cost and benefit ratio makes a wise decision.
