Solar panels are also known as photovoltaic solar modules, solar plates, solar PV modules, and solar power panels, etc. If you are planning to install a solar panel you may be wondering how much does a solar panel costs. Solar panels are made up of a bunch of 60-72 solar cells that convert sunlight into electricity.
Solar cells are made from an element called “silicon“. To manufacture the solar cells, fragments of silicon or silicon crystals are melted together in a mold and cut into wafers.
If we install two or more solar panels together and connect them with a solar inverter, the solar battery will then become a solar power system that can be used in houses, companies, schools, industries, etc. Solar panels are the main part of the solar system and all types of solar systems (off-grid solar systems, on-grid solar systems, and hybrid solar systems) contain the same type of solar panel.
Types of Solar Panels
There are various types of solar panels that have different capacities. This panel varies from each other on the basis of their material used, formation, etc. To provide a brief knowledge about all types of solar panels, we are listing their type below.
- Polycrystalline Solar Panel
- Monocrystalline Solar Panel
- Thin Film Solar Panel
Out of these solar panels, only polycrystalline solar panels and monocrystalline solar panels are the most successful panel to use for home solar systems and commercial solar systems
Polycrystalline Solar Panel
Polycrystalline solar panels are the most common type of solar panels. The efficiency rate of a polycrystalline solar panel is around 16%-17%. These solar panels are best to work under extreme weather conditions. To manufacture a polycrystalline solar panel, low purity silicon is used.
Monocrystalline Solar Panel
Monocrystalline solar panels are the second most successful type of solar panel. A monocrystalline panel is made out of pure high-quality silicon. The efficiency level of mono panels is more than poly panels i.e 19%-20%. These panels have blackish-hue on their surface.
Mono vs. Poly Technology
Difference Between A Polycrystalline Solar Panel And A Monocrystalline Solar Panel
| Poly-crystalline solar panels | Mono-crystalline solar panels |
| Cost-Effective. Panel efficiency up to 16%. Looks bluish in color. It takes more rooftop space. Low efficiency in cloudy weather. |
Expensive solar panel. Panel efficiency up to 20%. Looks black in color. It takes less rooftop space. Better efficiency even in low light. |
Which Type Of Solar Panel Is Best?
Solar panels efficiency refers to the amount of sunlight converted to electricity in a specific area. Under the above two types of solar panel technology, monocrystalline is the best in terms of efficiency.
The monocrystalline panels have the highest efficiency of up to 20%, require less space but they are a little more expensive than a polycrystalline solar panel. A 100-watt poly and monocrystalline panel will generate the same amount of power but the mono-crystalline panel will take up less space than a poly-crystalline panel.
- Mono-crystalline efficiency – 20%
- Poly-crystalline efficiency– 17%
Solar Panel Price
The most important factor that influences our mind at the time of purchasing solar panels is, ‘how much does a solar panel cost’. Normally, the prices of panels are measured in solar price per watt. Investment in solar is big and like a one-time investment. So if you are going to install a solar panel at your home or business, you should know the prices of solar panels. For your convenience, we are providing you the price list of all capacities and brand’s solar panels below.
