Solar Panels

What is the difference between mono and poly solar panels?

PV (photovoltaic) panels are made using silicon. The main difference between Monocrystalline & Polycrystalline silicon is the purity of the silicon. The higher the purity of the silicon, the better the solar cell will be at converting sunlight into electricity.

Monocrystalline solar cells are made from a single silicon structure, and in many cases a higher grade of silicon is used. This produces a solar panel with a higher efficiency. Another advantage of a monocrystalline solar cell is that it is space efficient – with a higher efficiency, you can often produce more power per square metre of panel.

Solar cells made from Polycrystalline silicon are produced by melting silicon into square moulds and slicing wafer-thin perfect squares, resulting in a light blue square pattern. Polycrystalline silicon solar panels are generally a bit cheaper than Monocrystalline, but they can also be slightly less efficient.

Astronergy was founded in 2006 and has established itself as a Tier 1 trusted solar panel manufacturer of monocrystalline and polycrystalline PV modules. Astronergy specializes in cutting-edge research, development and production of high-efficiency solar modules. With over 10 years of steady development, Astronergy achieves significant growth in terms of capacity expansion and downstream engagement.

Astronergy expanded its production capacity from 25 MW to 3,000 MW in the trend of embracing clean energy around the world. Astronergy is also one of the biggest solar project developers in China.

In 2014, Astronergy acquired Conergy’s production plant located in Germany and became the first Chinese solar company to establish a production facility in Germany. The merge of the German plant increased Astronergy’s market share in EU significantly combined with another 5 production sites around the world in Hangzhou, Haining, Jiuquan, Thailand and Malaysia.

Jinko Solar solar panels reviewJinko Solar is a Chinese company producing tier 1 panels. All the panels they currently sell in Australia are salt mist corrosion resistant and suitable for installation in any location. They carry a 10 year product warranty that is standard for the industry and they have an Australian office that provides that gives you someone in the country you can call if you have a problem.

Jinko Solar is one of the world’s largest manufacturer of solar panel manufacturers. In 2016 Jinko appeared to take the lead and their solar panel production for 2017 was from 8.5 to 9 7 gigawatts.  That is around 8 times as much as the whole of Australia installed in that year.

Manufacturing capex through the first nine months of 2018, reached US$385 million, however fourth quarter capex guidance was expected to be in the range of only US$15 million to US$16 million, according to the company. Image: JinkoSolar

Jinko solar have production facilities in China and one each in Malaysia, Portugal, and South Africa. China has the largest capacity. Its Malaysian factory can produce about 450 megawatts of Jinko panels, Portugal 200 megawatts, and South Africa 120 megawatts. The South African, Capetown assembly plant produces solar panels from imported parts, employs 250 locals, and is one of 5 solar manufacturing plants in South Africa.

Jinko’s employs around 15,000 people for the past three years while its production capacity has doubled. That’s the way things go these days thanks to automation and robotics.
