Simple Solar LED Lighting and Off-Grid Solar Power Facts

  • Written by NewsServices.com

There are some important basic facts that everyone should know about solar LED lighting and off-grid solar power systems. When these facts are understood, it is easy to see how these systems operate and why the systems have certain specifications to ensure that the system you have installed is operational.

System Sizing – Grid Dependent

All solar power systems are grid dependent, and one must calculate the average sun hours to determine the available sun for the local area that you are installing your system in. The calculation of sun hours and the length of the night are calculated so that the average amount of power consumed can be determined. If you used about 100 watts twenty-four hours a day, seven days a week, three hundred and sixty-five days a year, then you would be able to determine your need for solar power of about 750 watts. When the sun is not as powerful your installed system could pull energy from the power grid to power your system.

Solar Sun Hour – What is That?

This is a unit of measurement that solar companies use when they are deciding if the available sun for the location where they will be installing a solar power system. Systems that are tied to the power grid need an average of the amount of power they utilize so that they are constantly operational and there is no lag in service. Off-grid systems need the proper information gathered so that the system is located correctly. Data collected helps to gain an idea of the average during the month with December being the most critical for low solar collection.

Sunlight amounts vary between locations. Northern areas tend to have a few solar sun hours during winter and southern areas can have up to five or six solar sun hours in a day. The NREL or National Renewable Energy Laboratory provides accurate information on the best off-grid solar lighting and the operation of solar power systems.

Solar Power Away from the Sunbelt

Solar power systems are installed all around the world and modified to suit whatever area of the world they are located in. Solar installations located outside of the sunbelt must be more efficient because they have less available sunlight. The power system must be configured to ensure that the system operates inside or outside of the sunbelt. If more power is required than what is available, the system can be set to operate differently drawing power from the grid when sunlight is not available to power the system.

Operation of Solar Panels

Solar Panels operate during the day and generate power. The solar panel can generate power and then it will feed it to the system. This power can be stored in batteries for when the system does not have access to sunlight. Power generation can be beneficial in that when there is excess power generated, it can be fed into the grid and that power is utilized and sent to where it is needed within that system.

What is the Average Lifespan of a Solar Lighting System?

Commercial solar lighting and solar power systems can last for quite a long time if they are set up correctly with the proper sizing. Each part of the system has a certain life span, and the entire system should last up to 30 years with the correct maintenance procedures. Solar panels do not require much maintenance, just some simple cleaning. The system will need to have access to full sunlight so that means that nearby trees and obstacles must be removed so give the sun access to the panels.

Solar Panels

The components that make up solar power systems are usually warrantied for up to 25 years. There are no mechanical moving parts so when these panels are installed, they can last for quite some time. The most important part is that these panels receive full sun, not shade, so it is important to locate them in the right area where they will receive that full sun.

Solar power is one of the most reliable power sources known to man. With the endless energy that comes from the sun, there is no way that we are going to run out of fuel to power solar panels. This makes solar energy a truly renewable energy source that is green and safe. As solar panel systems continue to evolve, they are becoming more affordable and appealing to homeowners and business owners alike. If you have been thinking about having a solar energy system installed, there is really no time like the present.
