We have all heard about solar energy and how solar systems are an economical and efficient alternative to generate electricity. Perhaps we have even considered looking for information to learn more about what the different types of solar systems are and what they offer. But how can you choose the best option?
To understand what the different types of solar systems are, you have to start by explaining what solar energy is and how it works. Solar energy is the energy that is obtained directly from the sun. It is known as renewable and clean energy since it is obtained directly from solar radiation that reaches the Earth in the form of light, heat, or ultraviolet rays. But in order to use this solar energy in our homes, it is necessary to convert it into electricity through photovoltaic systems. Photovoltaic systems convert the light we receive from the sun into electricity so that it can be used as electricity in homes or businesses.
Two types of solar systems
There are mainly two types of solar systems that work by converting solar energy into electricity. This is achieved through the installation of solar panels that are formed by photovoltaic cells that collect the rays of sunlight directly and convert them into direct current or DC. Then, an inverter receives the direct current generated by the solar panels and converts it into alternating current or AC which is the most commonly used type of electricity. Among the solar systems available are the solar system that is connected to the grid (grid-tied) or the one that is completely isolated from the grid. A third option that currently enjoys a lot of popularity is to be connected to the power grid, but with a battery back-up system.
System connected to the mains
The grid-tied system that is connected to the power grid allows users to use all the energy they need for their home, but by being connected to the power grid (AEE) you can complement the use with that of the network and even exchanging the excess of your energy at no cost to you, in accordance with Law 114 of 2007. This system is the most economical, but it has a disadvantage that if there is no electricity from the network (AEE) it does not provide a system alternate.
Autonomous solar system
On the other hand, autonomous or remote solar systems include forms of storage, such as batteries, to supply energy in case it is needed since it is completely disconnected from the electricity grid (AEE) but is less efficient because it lacks energy conversion and more expensive since it needs a larger amount of batteries.
The alternative of the solar system tied to the grid or “grid-tied with backup” allows you to generate all the energy you need through the solar panels, store it through the connection to the network and use batteries to supply electricity in case the power grid fails. Either because you are interested in eliminating your dependence on the electricity grid, saving on your monthly energy bill, reducing environmental pollution or because you want to have electricity in your home or business 24 hours a day, there are specific types of solar systems that can be adjusted to your needs and your budget.
