When one creates a solar energy system, the important thing that is kept in mind is the method of collection. This is very important because if you want your solar energy system to be successful it must have an efficient collector which is able to collect energy from the sun in the best way possible. In the market one can find mainly three different types of collectors but the most popular and the most widely used collector in the market today is the Flat Plate collector.

What is A Flat Plate Collector?

What is A Flat Plate Collector

A flat plate collector basically consists of a rectangular box which is covered by a plastic glazing or a glass, and underneath this covering lays a metal plate. The heat is trapped in the rectangular box with the help of the plastic glazing or the glass covering. This heat is then absorbed by the metal plate which is colored to absorb maximum heat. This absorbed heat is then transferred to tubes which contain air or water. These tubes then carry this absorbed heat around the house and keep the house warm without the need of any heavy electrical appliances

Air and Liquid systems

There are two types of systems. One system contains air in the tubes and the other system contains liquid in the carrying tubes.

Air Systems

Air systems in which heat is carried around with the help of air are not very efficient. Read the full story

A set of photovoltaic consist of silicon wafers which absorb sunlight form the atmosphere and convert it into electricity. The electricity so produced is direct current (DC) which we cannot use directly to run our daily household electronic or electric devices. In order to convert the DC into alternating current (AC) we need an electronic deice commonly know as solar inverter. The current so generated by using the direct current by the inverter is used to power our daily household electricity consuming equipments.

Direct Current Functions

Direct Current Functions

Direct Current represents flow of electrons in one direction with a regular strength. The flow of the electrons is from negative node to the positive one. To understand the flow of direct current one can take case of batteries commonly used in vehicles or even smaller batteries used in battery operated devices. Other examples of DC are solar power cells, solar power systems etc. Although, almost every electronic circuit operates on DC but the problem with DC is it cannot be transmitted to use it away form its original place of generation.

Alternating Current Functions

Conversely the alternating current (AC) continues change its direction and its strength also keep variations. Probably due to the rapid change in directions of the current on alternates it is named alternating current. Step-up and Step-down transformers are used to increase and decrease respectively the voltage power of AC. Due to this functionality the AC is easy to transmit from the location of its generation to the locations of its use.

Many people have knowledge about the electricity and all use electricity in their houses, schools, offices etc. But all people don’t know about the direct current and the alternate current DC and AC respectively. They also don’t know what the sources of these AC and DC current are. One should have their knowledge which is beneficial for their own convenience. Solar panels also work on watts and store energy on their panels.

AC and DC Current

electrical generation

Electricity flows in two ways; either it will be the alternate current of the direct current. Electricity is just the flow of electrons, which moves along a conductor. The conductor may be wires etc. The difference between these two is the direction or flow of electrons is different in AC current and different in DC current. In DC current the electrons go in forward direction but in AC current the electrons go in forward direction and then come back in backward direction. The electricity in wall lights which are being used by us in houses is the AC current. AC current is in the light sockets which are being installed in houses, schools etc.

DC Watts

DC Watts can be quote in two ways. One is known as Standard Test Condition and it is very simple you just take the watt from the panel and multiply it with other panel .
