Solar power is a great way to save money. But, it has some drawbacks. You can’t see the solar panels. They are usually placed on the roof of a building. The sun shines in the windows, and you have to be right there to capture it. There are also weather conditions that can affect the performance of solar power systems.
One of the problems with solar energy is that the panels need to be in place to collect enough sunlight. Solar thermal energy systems concentrate and collect the sun to generate the high temperatures required to generate electric current using photovoltaic cells (PV). The collection and concentrated solar energy are then sent through a tracking system to a converter box that changes the temperature of the solar heat to household voltage. Photovoltaic (PV) cells produce direct current (DC) from the solar energy by the photoelectric effect. To change this into usable alternating current (AC), a generator is needed.
To store energy for a long time, a solar thermal power system must be large enough. It has to be located on the roof or side of a building. These solar thermal power systems are called solar thermal energy storage systems (STES). The two-plant facility has larger solar thermal energy storage systems. These facilities use a variety of technologies.
For a STES to work, there must be space available for prominent solar collectors and converters. The sunlight hits the mirrors that focus the light onto the solar panels. The light is then converted into AC using photovoltaic cells. The AC generated is then sent to the house.
Usually, the mirrors used in STES solar collector arrays are large silicon mirrors. These mirrors have been designed using the latest materials, like gallium arsenide (GHG). These materials are capable of absorbing a large amount of sunlight. This increases solar output. Since the mirrors are made of unique material, more solar production is absorbed, leading to larger solar panels and greater power output.
The main components used in STES solar power system are the solar collector, solar power converters and the solar trough solar power converters. The solar collector serves as the ‘apparatus’ for collecting sunlight and transferring it to solar cells. Since the system has to handle a large quantity of sunlight, the solar power converters are used. These devices transform the DC energy into AC energy. They also control the flow of current into the batteries.
Another important component is the solar power plant. The plants usually stand-alone and do not interact with the other components of the solar energy system. The main job of the plant is to store solar energy and change it into electricity. The stored electricity is normally sent to the mains of the house. But some of the plants also send electricity to the grid.
There are two types of solar power plants – the active and passive systems. The passive power plants are the most popular since they produce electricity at their own. They don’t need sunlight and do not need any storage batteries. In the active solar energy system, a power plant is required along with solar collectors, batteries and converters. The passive solar energy plants need less sunlight and power them on during cloudy days. These plants are also known as active solar power plants.
Now let’s have a look at concentrated solar power plants. These plants do not require sunlight to generate electricity. All the solar cells in these plants are designed to focus the sunlight. The concentrated solar power plants can use both, sunlight and wind to produce electricity. This is very convenient for areas which receive minimal sunlight or wind.
The technology is complicated and expensive, but it is one of the best ways to increase the net summer electric generation capacity of a house. A solar power tower is a great addition to the solar energy system. The solar power tower increases the amount of sunlight that falls on your roof, and this produces more electricity. The tower heats the water that is used for the hot water system.
In the future solar power systems may become a major contributor to the world’s electricity supply. One day solar energy may be the cheapest source of electricity people will need. Right now, solar energy only accounts for about 2% of the world’s electricity. Solar power may soon be the dominant source of electricity. If you want to invest in solar energy, consider getting a solar power system. They are relatively affordable.
