photovoltaic installation with surplus in an industrial warehouse"},"content":{"rendered":"\n<h2 class=\"wp-block-heading\"><strong>Sustainable resource management<\/strong><\/h2>\n\n<p class=\"wp-block-paragraph\">The implementation of self-consumption photovoltaic installations in industrial environments is a key step towards a <strong>more sustainable and efficient management of resources<\/strong>.<\/p>\n\n<p class=\"wp-block-paragraph\">In this context, PRODEN Group has assumed the execution of the project for the 15 kW photovoltaic self-consumption installation connected to the grid, intended to cover part of the energy demand of an industrial building located in the municipality of Molins de Rei (Barcelona).<\/p>\n\n<h2 class=\"wp-block-heading\"><strong>Main characteristics of the project<\/strong><\/h2>\n\n<p class=\"wp-block-paragraph\">Rated power: 15 kW.<\/p>\n\n<p class=\"wp-block-paragraph\">Number of modules: 30 high efficiency photovoltaic panels.<\/p>\n\n<p class=\"wp-block-paragraph\">Layout: flat roof with 0\u00b0 slope.<\/p>\n\n<p class=\"wp-block-paragraph\">Conversion system: inverter connected to the grid.<\/p>\n\n<p class=\"wp-block-paragraph\">Type of supply: self-consumption with surplus with compensation.<\/p>\n\n<h2 class=\"wp-block-heading\"><strong>Project objective<\/strong><\/h2>\n\n<p class=\"wp-block-paragraph\">The objective of the project was to define the technical, material and regulatory conditions applicable to the design and execution of the installation, guaranteeing its technical feasibility, legal compliance and safety, in addition to serving as a basis for obtaining licenses and authorizations from the competent authorities and agencies.<\/p>\n\n<p class=\"wp-block-paragraph\">The PVGIS estimation program for any point in the world (except for the poles) provides us with:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>the line on the horizon according to the location<\/li>\n\n\n\n<li>Monthly Irradiance on a fixed plane<\/li>\n\n\n\n<li>Monthly photovoltaic energy production hours<\/li>\n\n\n\n<li>Monthly energy production of the photovoltaic system<\/li>\n<\/ul>\n\n<h2 class=\"wp-block-heading\"><strong>Applicable regulations and legal framework<\/strong><\/h2>\n\n<p class=\"wp-block-paragraph\">The installation is governed by current legislation on electric self-consumption and industrial safety, among which the following stand out:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>New Low Voltage Electrotechnical Regulation according to Royal Decree 842\/2002 of August 2, 2002, both in terms of general and specific regulations, and its complementary technical instructions, according to table 1, depending on the use of the installation, and its subsequent modifications.<\/li>\n\n\n\n<li>Royal Decree 244\/2019 of April 5, 2009, which regulates the administrative, technical and economic conditions for the self-consumption of electricity.<\/li>\n\n\n\n<li>Royal Decree 1627\/97 of October 24, 1997, establishing the minimum Health and Safety provisions.<\/li>\n\n\n\n<li>Norms established by the Supply Company as well as the Municipal Ordinances of the City Council, and all those that affect the installation at the time of its execution.<\/li>\n\n\n\n<li>Regulation (EU) No. 305\/2011 of 9 March 2011 laying down harmonized conditions for the marketing of construction products.<\/li>\n\n\n\n<li>LAW 24\/2013, of December 26, 2013, on the Electricity Sector.<\/li>\n\n\n\n<li>ROYAL DECREE 9\/2013, of July 12, 2013, adopting urgent measures for the financial stability of the electricity system.<\/li>\n\n\n\n<li>ROYAL DECREE 1110\/2007, of August 24, which approves the unified regulation of measurement points of the electricity system.<\/li>\n\n\n\n<li>ROYAL DECREE 1699\/2011, of November 18, which regulates the connection to the grid of small power production facilities.<\/li>\n\n\n\n<li>ROYAL DECREE 413\/2014, of June 6, which regulates the connection and the activity of electricity production from renewable energy sources, cogeneration and waste.<\/li>\n\n\n\n<li>ROYAL DECREE 900\/2015, of October 9, which regulates the administrative, technical and economic conditions of the modalities of electricity supply with self-consumption and production with self-consumption.<\/li>\n\n\n\n<li>ROYAL DECREE-Law 15\/2018, of October 5, on urgent measures for energy transition and consumer protection.<\/li>\n<\/ul>\n\n<h2 class=\"wp-block-heading\"><strong>Materials and equipment<\/strong><\/h2>\n\n<p class=\"wp-block-paragraph\">The materials and equipment used were mainly:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>Mono-crystalline silicon photovoltaic modules with support structure adapted to flat roofs.<\/li>\n\n\n\n<li>Grid-connected inverter with integrated protections and monitoring systems.<\/li>\n\n\n\n<li>Electrical protection and switching panels, with overcurrent and overvoltage protection.<\/li>\n\n\n\n<li>Wiring and conduits dimensioned according to REBT.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">This action will <strong>optimize the<\/strong> plant&#8217;s <strong>energy consumption<\/strong>, <strong>reduce operating costs and contribute to environmental sustainability<\/strong> through the generation of renewable energy and the compensation of surpluses in the grid.<\/p>\n\n<h3 class=\"wp-block-heading\"><strong>PRODEN Group: Trusted engineering for a sustainable future<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">This project consolidates PRODEN Group as a benchmark in the improvement of resource management towards an<strong> energy transition <\/strong>based on a sustainable, decarbonized, efficient and decentralized system, in which renewable energies and energy efficiency play a central role.<\/p>\n\n<h4
