Most Common Types of Solar Panels

For the past 10 years, solar power has not been considered to be helpful since for some people, their benefits are implausible. But today, the concept of solar energy has hit its tremendous place. Since coals and fossil fuels are experiencing limited supply and are consumed much sooner, photovoltaic — a branch of technology that concerns on electric current — utilizes solar energy in the form of solar panels in homes as an alternative source of electricity.

It is no secret that the time solar panel is first launched to the market, many residential and commercial customers who want to generate their electricity with solar power are discouraged mainly for the reason of hefty upfront cost. To mitigate this issue, solar installers and developers generated the concept of providing solar power without requiring the customer to own a solar electric system. As a result, more and more households are considering the use of solar energy.

Types of Solar Panels

There are different types of solar panels and as a buyer, you might be confused which one best suits your taste. The following are the most common types of solar panels:

Monocrystalline silicon (mono-silicon or single silicon). This type of panel has a slice cut form of solar cells that is purely drawn in crystalline silicon bars. Monocrystalline silicon panels work best during bright sunshine as the cells are aligned in a particular direction causing the rays of light to gleam on them in a perfect angle.

Polycrystalline silicon (multicrystalline, multi-silicon, ribbon). This type of panel is formed into a perfectly squared wafer. The alignment of the blocks is helpful for the cell to work better from light at all angles as well as in low light. As compared to Monocrystalline, the installation process of polycrystalline solar panels is simpler and cheaper. In addition, the amount of waste silicon is less compared to Monocrystalline.

Hybrid Panels. Hybrid panels have thin layers made from amorphous solar film. This is the most efficient panel available to date as they occupy lesser space on your roof.

Black Frames and Black Backed Panels. Black frames are composed of completely black panels with a black backing behind the cells to give a much better appearance on traditional cottages with dark coloured tiles or with slate roofs.

Thin-Film Solar Cells (TFSC). Perhaps, the major boon in installing thin-film solar cells type is it is cheaper to manufacture than crystalline solar cells. Also, it is flexible to many types of potential applications. TFSC  has the following components:

Amorphous Silicon (a-Si) Solar Cells

Cadmium Telluride (CdTe) Solar Cells

Copper Indium Gallium Selenide (CIS/CIGS) Solar Cells

BIPV (building integrated photovoltaics). BIPV looks like a real roofing tile but they are less efficient and expensive compared to traditional solar-powered roofs.

Solar hot water (thermal) panels. This type of solar panel has nothing to do with electricity. Solar hot water panels work by producing hot water for homes which in turn provide a heat-and- air conditioning system.

Tips To Buy the Best Solar Panel

Before investing in solar panels, check the cost, the panel quality, temperature coefficient, light conversion efficiency, embodied energy, durability, warranty, longevity, size, watts, and types of solar cell used.

All in all, the following are the major points you should bear in mind when selecting solar panels for your home:

1. Consider the manufacturing process and the materials used.

2. Cite some reviews on how solar panels work in real situations.

3. Determine warranty and free-services for the panels.

4. Review reputable companies, like Hawaii Metal Roofing Supply, that have successful records in manufacturing solar panel products.
