TSO, The South Oracle, a photovoltaic engineering company and pioneer of self-consumption in Spain, is in charge of designing and providing, with its ultralight solar panels, the plant that will supply solar energy to the Spain Pavilion at Expo 2020 Dubai,the first Universal Exhibition to be held in the Middle East and which will be inaugurated on October 20th. This initiative comes after the sponsorship agreement reached with Accion Cultural Española (AC/E),which is the public company responsible for managing Spain’s presence at the Universal and International Exhibitions.

The Pamplona City Council has chosen TSO’s ultralight panel to install a photovoltaic plant for self-consumption on the new sustainable roof of the Public Safety building, where the Municipal Police is located. The project has been carried out by Construcciones Leache, S. L. with an investment of 197,169 Euros.
This construction company has provided the Public Safety building in Pamplona with a modular roof made of wood from sustainable forests, in which they are integrated 266 ultralight flexible solar panels, which are exclusive products of the Sevillian company TSO, The South Oracle.
The photovoltaic plant of about 80 kW, with an estimated production of 95 MWh per year, will cover up to 20% of the energy consumed by the building. In terms of aesthetics, TSO has guaranteed a zero-visual impact with the total integration of their ultralight panels on the new sustainable roof. This is possible thanks to the technical features of these exclusive solar panels, which are flexible, glassfree, weigh less than 5 kilos and can be customized and adapted to any surface, reducing the installation time by up to 70% compared to that used in photovoltaic installations with conventional panels.
For this project, the ultralight TSO panel selected has no profile, has its junction box on the front and is composed by 60 monocrystalline cells, giving it a maximum power of 290 watts. The photovoltaic plant is made up of 38 rows of seven panels each, all of them bonded with a special polymer along a 900 square meters surface. This roof is supported and fixed on the existing one, serving also as waterproofing and improving the thermal insulation of the building. It is a ‘2 in 1’ system called ‘plug and play’ (roof plus photovoltaic installation) connected to the building’s interior network.
The electrical connection of these panels also presents an innovative solution. It has been integrated into a smart micro-network in the same building using BeePlanet’s reused second life battery storage, V2G technology charging posts for municipal electric vehicles and micro-network control technology developed by CENER. All this action is part of the European Horizon 2020 project called Stardust, to which the Pamplona City Council is a partner.
Furthermore, the Sevillian company TSO is a pioneer in the participation of photovoltaic integration projects in surfaces, buildings or existing structures. Some examples of this are the photovoltaic solar plant integrated in the carports of the Emirates Towers parking lot in Dubai and in the façade of Tower 2 in Seville, being this latter the first architectural integration in an existing façade in Europe.
TSO, The South Oracle, has patented an exclusive software for the automatic identification of failures in the images taken withdronein solar panels, which in addition to guaranteeing the maintenance of photovoltaic plants, also allows repowering.
In order to develop this project called OSR, Optimized Solar Repowering,TSO has a team of engineers and scientists within the Biomedical Technology Centre of the Polytechnic University of Madrid(Universidad Politécnica de Madrid) who work with leading-edge technology to complete this software that will be launched on the market in the first quarter of 2020.
What is OSR?
After an exhaustive analysis of photovoltaic plants in Europe, TSO’s R&D department saw the need to accelerate the maintenance process, minimizing costs and its duration. Therefore, the research focused on developing a computer system connected to drones, the aim of which was to provide in record time, a complete report of the current status of each photovoltaic panel within a plant.
Thus OSR, the preventive-predictive and corrective Smart Solar Maintenance (SSM) software, was born, which through thermography and visible image with drone also guarantees the Repowering/Revamping of solar plants, detecting failures in solar modules instantly and allowing the reinstallation of damaged panels for optimal solar production, even offering an economic study of such repowering/revamping. In this way, OSR will be presented as an innovative solution in the updating of photovoltaic plants that have already completed their warranty period and need to return to full performance.
With this software, TSO will put an end to the problems many current installations have nowadays, which gradually affect their production during their useful life, by predicting the panels that are going to fail before compliance with the guarantee and those that have to be changed in plants that have completed 10 years of operation and are therefore out of guarantee. Reports of this company indicate that around 6-8% of the solar modules present failures in plants installed 10 years ago and that 2% of the modules will fail throughout their useful life in any solar plant.
In conclusion, OSRwill cover three existing needs in photovoltaic plants. Firstly, the preventive-predictive and corrective(SSM); secondly, the plant repowering/revamping to optimize the production and finally, the economic study and the new proposal that will guarantee the maximum profitability of the solar plant.
Last October 30th, TSO, The South Oracle participated in the Agro-industry efficiency seminar, held at CADE Las Cabezas de San Juan (Seville). The event was organized by Andalucía Emprende, Junta de Andalucía foundation, and has for objective raising awareness among businessmen as the urgency of taking actions for energy efficiency to meet required CO2 emissions reduction.

As, last may, in similar previous event in Estepa (Seville), TSO has newly participated in this seminar with a presentation of the energy services contracts added value by its CEO, Antonio Calo, who spoke about the existing models, defined the guaranteed savings, and their set up. Next, the CEO of TSOkept talking about the advantages for companies to take actions for energy efficiency and explained ECO20 certification seal. This quality certificate differentiates those companies powered by solar energy, making them relevant from their competitors.

The clinic will have a solar plant of 41.6 kWpfor instant self-consumption, which will be installed over its 200 square meter rooftop space with the ultralight flexible solar panel, exclusive of TSO.
This installation will cover 89.35% of health center’s annual electricity day hours consumption and will reduce its annual emissions of CO2 in 28.600 kg, reaching an accumulated decrease of 673.700 kg throughout its estimated useful life.
Through PPA contracts,TSO offers their customers a non-risk way of financing while it takes care of all the bureaucracy system, engineering, installation to start-up the photovoltaic solar plant. In addition, the customer fixes his electricity price for 10 years, independently to electricity market prices, and will benefit from 100% of the savings.
Other advantages of TSOPPA contract is the seal ECO20® , which certifies that the healthcare center is powered with electricity from the sun.
Similarly, on December in 2017, The South Oracle was pioneer in the photovoltaic market with the first PPA contract into Spanish agro-food sector. The beneficiary company was Patatas Arrebola Group, a Sevillian firm, which now has an instant self-consumption solar photovoltaic plant of 41.28 kWp, with an annual production of 50,000 kWh. (It reduces 26 tons of CO2 emissions per year).
