Learn interesting and useful facts about solar power systems and find out why they are becoming a popular source of alternative energy.
Over the past few years, there has been a truly remarkable upsurge in the demand for solar energy systems in most countries including the United States. As a natural consequence, people are currently interested to know all about these systems. The function of these systems can be stated in a straightforward manner – the use of the sun’s rays to generate electricity. Hence, topics like how these devices actually function, the process by which sunlight is trapped, processed and whether the systems can continue to function normally, have to be examined with due care. This article is devoted to the discussion of precisely these issues.
The actual process starts when the photons that are present in the rays of the sun are trapped by the silicon wafers of the solar power systems. DC electrical power is then generated from the captured photons and this DC current, in turn, is converted to usable 120 volt AC electricity. The systems hence, need to be connected to either an electrical grid or to the electrical setup of a home directly. A problem might arise if all people associated with the sales of solar power systems do not know the necessary details about the devices. Hence, prudence and discretion are called for, when you are selecting a supplier for domestic use. Ideally, the user must check the prior records, credentials and the expertise of the company as well.
Different factors have to be kept under consideration, when one selects a solar power system. Such important factors include: i). the add-on features that come with a grid-tied solar system, ii). Chief parts of the system, iii). Monitoring the progress of the system, iv). The main factors of success, v). The ways to operate and properly maintain the unit.
Solar power systems that are grid-tied: This kind of system has a lesser cost than the other types. A grid-tied solar energy system is ideal for the processing and production of electric current at all times of the day. Without a grid, the system can work only as long as sunlight is available. As soon as evening sets in, it comes to a stop, and this is hardly desirable. Battery backups can be opted for, but they are too expensive. In fact, grid-tied solar energy systems offer the best solution to this problem. Users can easily get the power they require at night from the electricity that gets stored on the grid during the day. And if there is something extra, then it can even be sold off. And this gives an opportunity to recover some of the investments made initially.
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 internet: Web browsers can be used to monitor the performance and efficiency of the systems. Even portable gadgets can be used for this purpose.
Main factors of success – Most established suppliers of solar energy units are aware of these factors. The success factors include monitoring the climate to facilitate the process of electricity generation, and determining the direction in which, if the system is placed, it would yield the best results. As a case in point, if there is fog in the morning at San Francisco, chances are that the best yields of electric power would be available in the middle of the afternoon. TVs and computers that have been powered but are kept plugged in, and any other such ‘phantom loads’ need also be eliminated to ensure that the system operates at best efficiency. If all the above factors are closely examined, and all requisite measures are adopted, the system is more likely to operate in an effective manner.
Mode of working and maintaining the system – The solar power panels need to be thoroughly cleaned at least once a year. The batteries (if present) used in the system need also be replaced after every 5 to 10 years.
The benefits of solar power become evident as soon as such a system has been set up. However, a prior thorough knowledge regarding the installation procedures, the ideal place where it should be installed, the wiring, as well as the information about the safety measures is required. Users also need to know from where they can get cheap components as well as free batteries from. Once installed properly, solar power systems can indeed be great additions to any home.
