Mono crystalline solar cells are the earliest form of solar cells. With the growing demand of energy in the world, the concept of renewable energy has attracted the attention of not only the scientists and researchers but also the consumers and common people.

How are mono crystalline solar cells formed?

There are several steps involved in their production and formation. But the basic outline of the procedure involves the following steps.

  • Cylindrical ingots of silicon are used for the preparation of these solar cells.
  • Ingots are long rectangular or oblong blocks of silicon.
  • Thin wafers are cut out of these oblong blocks of silicon.
  • The process of sawing is used the most frequently for cutting of the wafers.
  • Great care has to be taken since the wafers are extremely thin and the dimensions have to be very accurate.
  • Another important thing which is required is a rigid glass substrate.
  • The wafers of silicon are then deposited on the glass substrate.

Appearance of Mono crystalline Solar cells

These cells appear to be polka dotted. They have gaps at all corners of the cell this shape gives them a unique appearance. Among all kinds of solar cells, these cells are the most easy to recognize.

The use of solar energy as an alternative source of energy is on the rise. Several equipments and house hold items are run on the power generated from the sunlight. These items include solar powered lights, solar inverters, generators, and solar water heaters. Solar heater provides the facility of warm water whenever needed. It is no doubt that solar water heater come with advantages, but there are certain disadvantages of solar water heater as well.

Soaring Prices of Solar Water Heaters

Solar Water Heater

There are several types of water heaters available in the market. People purchase these heaters according to their affordability and according to their needs. Though the sale of products which run on solar energy is on the rise, but not all the people can afford solar water heater, or require them. There are heaters which use gas or electricity to produce heat. These heaters are cheaper than the solar water heaters.

If a comparison is made between the prices of gas or electric heater to the prices of solar heater, you will see an astonishing difference. A solar water heater can cost you from 800 USD to 32, 00 USD. The cost of solar panel used in the heater makes the price of the solar water heater high.
