When you consider whether it is worth installing photovoltaic solar panels in companies or at home, the first things to consider are the necessary steps to make self-consumption legal, thats why you need to know about permits and procedures for their legal use . 

Without a doubt, photovoltaic consumption is an excellent investment, so it is good to know all the aspects involved.

When you start researching, you will know that there are different options: with surplus and without surplus. In this article, we are going to learn how to legalize a solar photovoltaic installation with surplus, which brings many benefits to the long term.

Why do solar panels require permission?

Although the installation of solar panels is covered by whoever wishes to use them, regardless of the type of location, whether it is a home, office, shopping mall, etc., the installation companies require a permit approved by the legal authorities, depending on where you are located.

These agencies have already approved the use of electricity provided by the state or by private companies; to use solar panels you will need approval and legalization, parallel to this, you need to notify the electric company about these new changes.

The truth is that efficient self-consumption is not very popular yet, but its use is valid. The documentation and paperwork to obtain approval are not as cumbersome as you might expect.

What is a surplus photovoltaic solar panel installation?

It is especially important to know what surplus self-consumption is. This type of photovoltaic installation not just provides you with energy for your home; all the energy produced in your panels which you do not consume can be fed directly into the electricity grid. 

In more modernized places you could receive compensation for the donation of this energy but it all depends on the conditions and the place where you live.

Steps to legalize a self-consumption installation with surplus:

  • Design of the photovoltaic installation

The type of grid connection and the power you will install is relevant to know what type of document is required. A certified technician must sign the design document, after evaluating the site and creating the design plan.

For high voltage installations, it is also necessary to submit a technical project and a report.

  • Energy compensation:

If you are going to receive compensation in your electricity bill thanks to the discharge of surplus energy to the grid, you must follow other requirements. 

  • The power can not exceed 100kW.
  • The energy must come from renewable sources
  • To have a contract with a trading company for the compensation of the surplus
  • Do not have another remuneration system associated with that installation

The installation company’s technician will process these documents. An authorized installer must sign the electric bulletin, and the solar panel installation company must stamp the service certificate.

The distribution company grants access to the distribution line.

  • Environmental and public utility authorizations required for approval

Installations with a capacity of less than 100 kW do not require environmental impact or public utility permits. 

  • Building permits

To obtain this license, the company must be guided by the municipal regulations since the installation depends on the requirements of the locality where the solar panels will be placed. You can contact the local town hall directly for more information.

  • Performing the installation

Different factors are involved; it all depends on the voltage of the installation. Home installations are considered low voltage; therefore there are a series of specific criteria for their installation.

  • Installation certificates

Once the installation work is completed, certificates must be issued directly to the local town hall. This certificate is issued by the installation company, in this case, URSUS.

In installations of a higher power, you must also submit a certificate of completion signed by a specialized technician.

  • On-site inspections

In this case, high-voltage photovoltaic installations must be periodically inspected by local control authorities.

Other procedures include:

  • Authorization for the operation of photovoltaic solar panels.
  • Access and energy supply contract
  • Registration in the local self-consumption registry
