Photo voltaic panels have change into a well-liked possibility for producing electrical energy as a consequence of their clear and renewable nature. The 2 hottest sorts of photo voltaic panels are CIGS photo voltaic panels and polycrystalline photo voltaic panels. CIGS stands for Copper-Indium-Gallium-Selenide, whereas polycrystalline photo voltaic panels are made up of a number of crystalline silicon cells.
On this article, we’ll evaluate cigs photo voltaic panels vs polycrystalline, discussing their working mechanisms, benefits, and drawbacks. We may also evaluate the effectivity, value, sturdiness, flexibility, and warmth and light-weight absorption of each photo voltaic panels. Lastly, we’ll advocate the perfect photo voltaic panel kind based mostly on particular person wants and preferences.
CIGS Photo voltaic Panels
CIGS photo voltaic panels are made up of 4 components: copper, indium, gallium, and selenium. These components are deposited onto a substrate, comparable to glass or plastic, in skinny layers to create a photovoltaic cell. The CIGS cell converts daylight into electrical energy by absorbing gentle vitality and separating electrons from their atoms.
Benefits of CIGS Photo voltaic Panels
- Effectivity: CIGS photo voltaic panels have excessive conversion effectivity, starting from 14% to 22%. They’re able to producing extra electrical energy per unit space than polycrystalline photo voltaic panels.
- Flexibility: CIGS photo voltaic panels are versatile and could be made into varied shapes, permitting for extra design potentialities.
- Gentle Absorption: CIGS photo voltaic panels have a excessive absorption coefficient, which suggests they’ll take up extra gentle vitality per unit thickness than different photo voltaic panel varieties.
Disadvantages of CIGS Photo voltaic Panels
- Value: CIGS photo voltaic panels are dearer to provide than polycrystalline photo voltaic panels. The manufacturing course of is extra complicated, and the supplies used are dearer.
- Sturdiness: CIGS photo voltaic panels are much less sturdy than polycrystalline photo voltaic panels. They degrade sooner over time and have a shorter lifespan.
Polycrystalline Photo voltaic Panels
Polycrystalline photo voltaic panels are made up of a number of crystalline silicon cells. These cells are made by melting silicon and pouring it right into a mould to create a sq. or rectangular ingot. The ingot is then sliced into skinny wafers, that are then processed to create a photovoltaic cell.
Benefits of Polycrystalline Photo voltaic Panels
- Effectivity: Polycrystalline photo voltaic panels have a conversion effectivity of 15% to twenty%. Though they’re barely much less environment friendly than CIGS photo voltaic panels, they’re nonetheless able to producing a big quantity of electrical energy.
- Value: Polycrystalline photo voltaic panels are cheaper to provide than CIGS photo voltaic panels. The manufacturing course of is much less complicated, and the supplies used are cheaper.
- Sturdiness: Polycrystalline photo voltaic panels are extra sturdy than CIGS photo voltaic panels. They’ve an extended lifespan and may face up to harsh climate situations.
Disadvantages of Polycrystalline Photo voltaic Panels
- Inflexibility: Polycrystalline photo voltaic panels are inflexible and can’t be made into totally different shapes. This limits their design potentialities.
- Warmth Absorption: Polycrystalline photo voltaic panels take up extra warmth than CIGS photo voltaic panels, which may have an effect on their efficiency in high-temperature environments.
Comparability Between CIGS Photo voltaic Panels and Polycrystalline Photo voltaic Panels
Effectivity
CIGS photo voltaic panels are barely extra environment friendly than polycrystalline photo voltaic panels. Nevertheless, the distinction in effectivity will not be important sufficient to warrant the upper value of CIGS photo voltaic panels.
Value
Polycrystalline photo voltaic panels are cheaper to provide than CIGS photo voltaic panels. That is as a result of easier manufacturing course of and the decrease value of the supplies used. Polycrystalline photo voltaic panels are additionally extra extensively obtainable and could be bought at a decrease value per watt.
Sturdiness
Polycrystalline photo voltaic panels are extra sturdy than CIGS photo voltaic panels. They’ve an extended lifespan and may face up to harsh climate situations. Polycrystalline photo voltaic panels even have a decrease price of degradation over time than CIGS photo voltaic panel.
Flexibility and Inflexibility
CIGS photo voltaic panels are versatile and could be made into totally different shapes, whereas polycrystalline photo voltaic panels are inflexible and can’t be made into totally different shapes. This makes CIGS photo voltaic panels extra versatile when it comes to design potentialities.
Gentle and Warmth Absorption
CIGS photo voltaic panels have the next absorption coefficient than polycrystalline photo voltaic panels, which suggests they’ll take up extra gentle vitality per unit thickness than polycrystalline photo voltaic panels. Nevertheless, polycrystalline photo voltaic panels take up much less warmth than CIGS photo voltaic panels, which could be a bonus in high-temperature environments.
Conclusion
In conclusion, each CIGS photo voltaic panels and polycrystalline photo voltaic panels have their benefits and drawbacks. CIGS photo voltaic panels are extra environment friendly, versatile, and have the next gentle absorption coefficient, whereas polycrystalline photo voltaic panels are cheaper, extra sturdy, and have a decrease warmth absorption coefficient. The selection between the 2 photo voltaic panel varieties finally will depend on particular person wants and preferences.
If you’re in search of a photo voltaic panel that may be made into totally different shapes and designs, and you might be prepared to pay the next worth for a extra environment friendly panel, then CIGS photo voltaic panels could also be the best choice for you. Nevertheless, in case you are in search of a extra inexpensive photo voltaic panel that’s sturdy and may face up to harsh climate situations, then polycrystalline photo voltaic panels would be the more sensible choice.
Total, each CIGS photo voltaic panels and polycrystalline photo voltaic panels are efficient choices for producing electrical energy from the solar. The choice between the 2 must be based mostly on particular person components comparable to value, effectivity, sturdiness, and design potentialities.
If you’re in search of a dependable and high-quality photo voltaic panel model, we advocate BougeRV. They provide a variety of photo voltaic panel choices, together with polycrystalline photo voltaic panels, which can be sturdy and environment friendly.
