What is the Difference Between Monocrystalline and Polycrystalline Solar Panels?

What is the Difference Between Monocrystalline and Polycrystalline Solar Panels?

Solar panels take advantage of a powerful yet free energy source - the sun. In a single hour the sun transmits more energy to the earth's surface than the world uses in a year. Our guide outlines how you can use solar panels to make use of this free source of energy to generate electricity and hot water for you home. Types of solar panels The two main types of active solar panel systems are Monocrystalline Panels ,Polycrsytalline Panels (also known as multicrystalline)
The differences between these two types of solar panels relate to the manufacturing process rather than product characteristics. Monocrystalline solar cells are produced from a single crystal of silicon while polycrystalline solar cells are produced from a piece of silicon consisting of many crystals.
The solar cells in monocrystalline panels are slices cut from pure drawn crystalline silicon bars. The entire cell is aligned in one direction, which means that when the sun is shining brightly on them at the correct angle, they are extremely efficient. So, these panels work best in bright sunshine with the sun shining directly on them. They have a uniform blacker colour because they are absorbing most of the light. Pure cells are octagonal, so there is unused space in the corners when lots of cells are made into a solar module. Mono mono panels are slightly smaller than poly panels for the same power, but this is only really noticeable on industrial scale installations where you may be able to fit a higher overall power with monocrystalline.
Polycrystalline Panels (also known as multicrystalline)
Polycrystalline panels are made up from the silicon offcuts, moulded to form blocks and create a cell made up of several bits of pure crystal. Because the individual crystals are not necessarily all perfectly aligned together and there are losses at the joints between them, they are not quite as efficient. However, this mis-alignment can help in some circumstances, because the cells work better from light at all angles, in low light, etc. For this reason, I would argue that polycrystalline is slightly better suited to the UK’s duller conditions, but the difference is marginal.
The appearance is also different you can see the random crystal arrangement and the panels look a little bluer as they reflect some of the light. Since they are cut into rectangular blocks, there is very little wasted space on the panel and you do not see the little diamonds that are typical of mono or hybrid panels. Some people prefer this more uniform appearance, others like the diamonds. The choice is yours because the overall size and cost is very similar to monocrystalline.

How do solar cells work?

Solar (or photovoltaic) cells convert the sun’s energy into electricity. they rely on the the photoelectric effect: the ability of matter to emit electrons when a light is shone on it. The solar cells are made of silicon and other materials which made up of at least 2 semi-conductor layers, one layer called P layer with extra electrons, another is called N layer missing equivalent electrons.  When the sun shines on the solar cells, free electrons from the P layer flow to N layer. Then it forms the electrons current. When the sun shines on the solar cells, the sun will realize photons, which contains sun energy. Many of the photons are reflected, pass right through, or absorbed by the solar cell. As these  hit the silicon atoms of the solar cell, they transfer their energy to loose electrons, knocking them clean off the atoms. The photons could be compared to the white ball in a game of pool, which passes on its energy to the coloured balls it strikes. E lectrons are freed f

How to choose between a on-grid and a off-grid system

On Grid or off Grid Firstly, we should probably explain just what a grid is. A grid is a network that supplies electricity to consumers. Nothing is too complicated - it's the vehicle which supplies electricity to businesses and residences. But what’s the difference between on-grid and off-grid? Before you make decision, let’s take a closer look at the pros and cons. On grid Solar System On-grid solar systems allow you to connect your solar panel system to the electrical grid. Electricity generated by the solar panels is put into the grid during peak production. It is stored and then recovered whenever needed. On Grid systems do not require a battery, because the grid acts as the battery. With "net metering", the utility meter spins backwards and credits the solar system owner for their energy production to keep track of it.  Advantage Using renewable energy on the grid avoids most, if not all, the disadvantages of being off grid. The utility is like
