Remote Power Systems - The Use of Solar Energy to Supply the Needs of Remote
Determine the use
As with any electrical installation, you must first decide how much power is needed. This is particularly critical of the PV, since it most likely will be the only source of energy. We need a conservative estimate of the current, voltage and time of use of the system size. By doing this, remember that most devices have a maximum amperage at startup. Some devices use five times its short operating amperage during remote power systems.
Most electronic devices are designed to take over AC, because that is what our network offers. From solar generated current, which often need to use an inverter to convert DC to AC. If we can avoid this, we will save the expense of the investor, anywhere from 5-20% of the energy lost investment. Often at the expense of using DC devices is offset by the savings in a UPS and remote power systems reduction of solar panels. The use of AC and DC electronics increases the complexity of the installation, but can be achieved with good design.
When designing a system, the critical factor is what we call “days of autonomy”. It refers to how long the system drives, if you do not have the sun. This is important because going from one day to three days, the autonomy of self-determination of the triple in size and cost of the remote power systems. An example of critical application traffic might be a spy or a communication system.
In both cases must take into account how local climate and determine what a likely scenario for the day without sunshine. For most of U.S. semi-critical applications (e.g. lighting, security, signaling), which is the plan for the days 3-4 of battery life.
Mounting and enclosures
How do I install the system is important since most of these remote power systems will operate with minimal maintenance. Systems generally require smaller Mat and battery cabinets to keep the bad weather. Sealed or AGM batteries are preferred in these systems, since they require no maintenance or ventilation. Another consideration is the design wind load, weight of snow and hail, because the sites are exposed to extreme weather conditions. Many solar energy kits now come with remote power systems, solar panels, and speakers in one complete unit can be transported to site development and implementation of a very short time.
