Solar energy is a wonderful solution for many, brings new options that will be very convenient and attractive for many reasons. Below we explain some of them.

  • REDUCE YOUR CARBON FOOTPRINT: Join the planet’s carbonization plan and take care of the planet and yourself.
  • ECONOMIC SAVINGS: Using Solar Systems, such as solar panels, can drastically reduce your electricity consumption payments.
  • ECONOMIC PROTECTION: You are economically protected against increases in the cost of electricity.
  • COMPETITIVENESS: With the reduction of your electrical expenses, you will be one step ahead of your competition.
  • IT’S FREE: Solar energy is free and inexhaustible.
  • ADAPTABILITY: At any time you can add solar panels to an already installed system, this because the panels are modular; so that it could (if necessary) increase the available power and the available energy. 
  • 25 YEARS OF LIFE: Photovoltaic systems are guaranteed by their manufacturers to last up to 25 years and can continue to generate beyond that time. 

  • COMMITMENT SAMPLE: You will demonstrate a commitment to sustainability and the environment, which your customers will greatly appreciate. 
  • RELIABILITY: Even in severe conditions, solar systems remain a very reliable way to produce energy. 
  • LESS SOUND POLLUTION: The systems are quiet in operation.
  • EASY INSTALLATION: The systems install quickly and are attractive solutions for remote sites difficult to access.
  • AUTONOMY: The systems are capable of being 100% independent of the electricity network of the distribution company in your area. This is due to the possibility of using batteries that will store your produced energy.

We begin our edition of TYPES OF PHOTOVOLTAIC SYSTEMS, explaining the most economical system used by the vast majority of solar consumers, the INTERACTIVE SYSTEM

⦁ These types of systems exchange energy with the service NETWORK, be it the ICE, CNFL, among others. They can also be known as “interconnected” and “interactive” systems.
⦁ What differentiates them from traditional photovoltaic (PV) systems, is where they store their energy, since they do not need battery storage.
⦁ The user generates his own energy and the excess energy (if not used at the time it is produced) is sold to the distribution network to which they belong. This enters the NETWORK and is used by another user who needs it at the moment.
⦁ When the user requires more energy, and it is at a time when their panels are not generating energy (as at night), they will use energy that is extracted from the commercial network of their distributor.
⦁ In the case of Costa Rica, The user receives energy (electricity) from the NETWORK at a price much cheaper than that of another common consumer. As for example, at a commercial rate of ICE the cost kilowatt hour (kWh) is 71.8 crc; that same kWh will cost 27.8 crc for the user that feeds the PV power to the NETWORK.
⦁ In the event of a power failure by the distribution NETWORK, the inverter switches off automatically and does not continue to pass PV electricity to the NETWORK.
⦁ So there will be no electricity at that time, as there is no storage; so it is that in some systems batteries are also used, in case of failures by the distribution network.

In most countries, electricity is provided by a centralized generation. Centralized generation is when electricity is generated that is then transmitted through power lines to millions of end users. This is the type of Energy Generation has been used in Costa Rica for many years. Distributed energy is the ideal way to take advantage of Clean Source energy generation. In this case, the electricity generated by Solar Energy

What is distributed energy?

It is the generation and management of electrical energy in a De-Centralizedway. It is given as close as possible to its place of consumption using mostly renewable energy sources.


* In this case, for the interest of all, we will propose the definition according to the Costa Rican Energy Distribution System *

How does Distributed Energy for Self-Consumption work?

  1. Properly install a Solar Generation System in your home / commerce / industry.
  2. Solar panels capture solar energy and convert it into electricity. Thanks to the photoelectric effect, electricity travels in the form of direct current to an inverter that transforms it into alternating current.
  3. The current passes through a meter that records the generation of electricity.
  4. Finally to a  which distributes it throughout the building.

Solar Generation Systems with Distributed Energy are recommended for users who consume the vast majority of electricity during the day (daylight hours).


In this way, the electricity produced by the Solar Panels at the moment is consumed. Even so, there are always surpluses of Electric Power.

Energy needs to be reserved or used at the moment.

So the Energy NOT used by the user enters the National Energy Network. 


Storage of Distributed Energy is done in the National Energy Network.

BATTERIES ARE NOT USED


Frequent questions:

What happens if I don’t use electricity during the day? or If I only consume a part of the electricity that was generated during the day?
  1. The Energy surplus is injected into the National Energy Network.
  2. A bi-directional meter is installed.
    • Why a bi-directional meter? : This measures the energy that enters and is consumed from the National Energy Network,
When Solar Panels DO NOT generate Energy?

Solar Panels DO NOT generate Energy during the night and can generate less Energy levels on cloudy days.

In a Distributed Energy System, who generates the Energy of the National Energy Network?

You, your neighbors and the government. Being a De-Centralized System, it means that Energy is generated everywhere. So you and your neighbors can contribute to the generation of Distributed Energy in your community. Being a clean energy contributor and strengthening your sense of community.

Can I use at night the same energy that generated hours of sunshine?

Not really. The Electric Power generated during the day and not used, is not stored. But it is not wasted either, since it is immediately used by other users connected to the National Energy Network.

What about the surpluses?

The distribution companies will recognize up to 49% of the electricity it generates. This means that the Electricity you consume from the National Energy Network, during the night, will be charged at a lower cost than the established price. The cost of this rate is decided by the ARESEP.

That is to say: Energy at a lower cost, in recognition of its contribution to the national network.

What about the energy I injected into the network and that the distribution company did not recognize me?
  • The Energy you provide improves the efficiency of the National Energy Network.
  • Energy flow decreases from large generation plants.
  • It is clean energy: from a clean, renewable and free source. IT DOES NOT POLLUTE.

If you are going to install Solar Panels, remember that the ideal thing is that in your house the highest consumption of Electric Energy is during the day so that you can consume your own Free Energy

Solar Panels need very little maintenance. These are the cares and recommendations that Seléctrica suggests you follow to keep them in optimal conditions:

Care

Photovoltaic Modules (Solar Panels)
  • Clean the modules with water. Only the top.
  • If it becomes necessary to use more than water, you can apply a mild detergent. DO NOT use strong and abrasive detergents.
  • It is possible to use a windshield wiper to facilitate cleaning. Again, do not use fabrics that can cause some kind of damage to the panels.
  • Clean the panels early or late, when the panels are cold and do not suffer a thermal shock.
  • You can end up drying with a soft cloth or with the windshield wiper.

Solar Panel and Cleaning

recommendations

  • Avoid shadows: The growth of trees and other vegetation that can produce shadows on solar panels. This can lower their performance.
  • Consulting with experts on the solar issue: When you decide to install your solar generation system, look for people trained in the subject; To guarantee a good installation. In this way they will make a proper study of your particular case and will have professionals at your side who can always advise you in the future, if necessary.

Frequency:

The weather and how the Solar Panels look will be a key indicator to know. The frequency can be between 1 or 2 times a year, but it will always depend on the conditions they face, depending on the area of the country where the installation is located.

Why an Electric Verification?

The Electric Verification, is an indispensable requirement, to obtain the Operating Permit, by the Ministry of Health, which, for a few years, only grants this type of permits, if there is the aforementioned Electrical Verification, performed by an electrical engineer who holds CAP Certification (CFIA Professional Update Certificate).

The CAP engineer certifies and records the Electrical Verification, that the installation complies fully with what is established in the construction plans, with the use that will be given to the service, as well as with the voltage needs that are had, so that the building receives, in a safe way, the electrical supply.

As stated in the previous paragraphs, we can conclude that, without Electric Verification, we do not have an Operating Permit and without this permission, we do not have an electrical supply to operate, hence, therefore, the importance of an Electrical Verification.

Why do I need an Operating Permit?

There is an obligation, for all physical businesses, industries and meeting centers, to provide their buildings, with electrical installations that comply with current regulations, electrical safety of the NEC, National Electrical Code. In order for any of these buildings to function freely, you must have an Operating Permit.

An Operating Permit certifies with guarantees that, at least, the electrical installation of a building is completely safe and reliable, for the people who use it and it is for this importance, that prior to the permit, a CAP engineer (the only certificates in terms of training and updating, on the latest electrical safety regulations of the NEC, National Electrical Code), must perform and certify a Electrical Verification.
