Grid tied solar power systems are by far the most common types of solar power systems. These systems have been adopted by a great number of people. If you are considering installing a grid tied solar power system in your home then you should first fully understand all components of grid ties solar power systems.

Utility Connected Systems

Utility Connected Systems

Utility connected system create electricity from the sun by a process and then this energy is supplied to the house where it is needed according to the amount that is needed, while the surplus amount of energy that remains unused is moved to the utility grid. According to the Public Utility Regulatory Act of 1978 (PURPA), all public utilities are directed to buy the surplus amount of energy from small energy producers, for example, you and your home.

Net-Metering

The above process is actually called net-metering that simple means that the public utility has to pay you for the electricity which you give back into the utility grid. In net-metering your electricity meter runs in backward direction and gives you credit on your electricity bill. However, it is not necessary for the public utility to pay back you the same rate that you usually pay off them for using the electricity. In simple words it indicates that there is often a gap between the utility rates.

Types of Grid Tied Solar Power Systems

Generally, there are two distinct types of grid-tied solar power systems hat are readily available at marketplace. These are system with battery back up and system without battery back up.

Grid –Tied System With Battery Back Up System

This type of grid tied system comes with a built-in battery that provides energy to your house during the absence of sunlight like during nights and cloudy days. Read the full story

With the passage of time advancements are coming in solar technology. This technology is improving and providing affordable energy. The proof of the advancement is new solar cells, the related industry is expanding and innovations are coming day by day. New one is better from the previous one. Now solar cells are available type of sizes and shapes.

Three generations of the solar cells

Three generations of the solar cells

You will find three generations of the cells which the solar industry has produced, each of them have cells of their own kind. In the very first generation you will find silicon-based cells. In the second generation variety of cells were introduced, these cells were mainly coated with a thin-film moniker and silicon is still used in these cells. To achieve maximum efficiency at low production coast, in the third generation cells the edges of the cells were cut. Every cell coming out of these generations has its own characteristic.

The solar cells are mainly differentiated by their size, shape and their semiconductor material. The solar cells having same material can also be differentiated further on the basis of unique characteristics. This characteristic separates one cell from other and also separates solar modules from one another.

Mono-crystalline solar cells

The mono-crystalline solar cell is known as father of modern solar power system. These cells are single-crystal and are made from a block of silicon known as cylindrical ingot. Read the full story

The working of solar panels is not a complex thing to understand. It is very simple and can easily be understood. In this simple process, sunlight strikes a certain type of material where it excites electrons and generates a current and voltage. That voltage can be utilized to empower devices. Following is the explanation of the working of solar panels.

Silicon as Semiconductor

Silicon as Semiconductor

Silicon is obtained from the earth. It is one of the most abundant elements of the earth. It is readily avoidable in all types of sand and rocks. Silicon is a semi conductor that is used for various purposes. Copper is also used as conductor in copper wires. Rubber is an insulator that is used to coat the copper wire. Silicon is half insulator and half conductor that is why it is known as semi-conductor. Read the full story

Disadventages of Solar Water Heater

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.
