Solar Power Systems: Are They Worth It?
Learn interesting and useful facts about solar power systems and find out why they are becoming a popular source of alternative energy.
Most people now are aware of the benefits of solar power systems, which can generate electricity from the rays of the sun. This widespread awareness is undoubtedly, mainly because of the ever-increasing popularity of these systems in all parts of the US, as well as in various other nations. Hence, an understanding of how these systems function should be an interesting study. The process, in which the solar power systems can trap, store and process energy to produce electricity, as also their method of working on a cloudy day when there is no sun in the sky, would form the main focus of this discourse.
The rays of the sun comprises of photons. These photons are trapped by the silicon wafers of the solar power systems and converted into DC electrical current. Once this DC power is changed into usable forms of 120 volt AC electrical power, this renewable current source can be directly plugged on to an electrical grid, or the electrical setup of a building. However, the various intricate hazards as also their advantages and disadvantages are not known by most and this can be a problem. Thus, when a person chooses one particular company for the installation of the system at his/her home or office, (s)he must be cautious and be aware of all relevant data. Ideally, the past records of the company, as also the quality of work rendered before should be looked into.
There are certain specific factors that need to be discussed separately to get a hang of the working of the systems. These factors include the add-on features of the system that is grid-tied, the primary parts of the setup, monitoring the performance over the web, the main causes of success and the proper way to run and preserve the solar energy system.
A solar power system that is grid-tied: Grid-tied solar energy systems represent an ideal device for generating electricity at all times during the day. These systems are cheaper as well. Solar power systems generally can easily produce electricity as long as sunlight is available during the day, but they stop working at night, and this is hardly desirable. If people opt for grid-tied solar power systems, the energy stored on the grid can be drawn upon to generate electricity at night. Excess electricity can also be sold off in exchange of money and this offsets the cost of electricity generation. If these grid-tied systems are not used, battery backups, that have a much higher price, need to be opted for.
Chief components of solar power systems: At the core of the solar power systems are the solar or photovoltaic cells. Generally, a ‘module’ is created by assembling several of these cells. Once some of these modules are attached together, we can create a solar panel. The panel then needs to be installed at such sites that receive abundant sunlight during most parts of the day, such as on the rooftop. Even those who are not experts have frequently seen these solar panels, which are rather prominent anyway. Hence, the panels can be said to be the point of introduction of people to solar power systems.
There are a number of other components too, apart from the panels. For generation of 120 volt AC current that would have the requisite cycles and would be usable, an inverter is used, through which the DC electrical power is passed. Wires are also used to keep all the different components of these systems attached. Clamps and stands, which are non-conducting in nature, are used to keep the panel in the recommended position, while, for installing the systems on top of roofs, racks are used. Make all these available and you can be sure that the system will work just fine.
Monitoring via the web: This allows people to keep a close eye on the way of working of the solar power systems. This monitoring can be done using different portable gadgets as well. Several web browsers are also used for this purpose.
Main factors for success: Does your solar energy system contain ‘phantom loads’ in the form of computers or television sets, which are kept connected to the solar power system, even when these devices are powered down? For efficient performance, such ‘phantom loads’ have to be removed. A study of the climate is also required. As an example, let us consider that, the morning in San Francisco is foggy. This is a clear indication that a good amount of electricity is likely to be available during the afternoon period. The direction in which electric current would be produced at optimal level is another of the key success factors. All solar energy system supplying companies are aware of these points.
Operating and properly maintaining the system: Solar power systems should ideally be cleansed once every 12 months. In case batteries are present, they also need to be replaced after a gap of 5 to 10 years.
There are several benefits to be enjoyed once solar power systems are installed. You should ideally consult a manual that offers detailed instructions on the procedure of installing the system, the best spot where it should be placed, as well as wiring the system. Such a guide would also let you know how you can get the components at reduced prices, the batteries for free, and the safety measures as well. All these instructions would help you greatly in setting up efficiently your home solar power system.
