State-of-the-art drones check renewable installations

Specifically, Endesa has used a Matrice 210 drone equipped with a Zenmuse XT2 thermal imaging camera to check part of the company's three photovoltaic plants in Badajoz.

Source: Digital Region

There are three installations located in Casas de Don Pedro and Talarrubias - Navavillar, Valdecaballero and Castilblanco - with 372,000 solar modules.

The drones used to fly over these facilities are multi-rotor and quadcopters, which allow for "greater stability" in the event of wind, even with the addition of the latest generation photographic equipment with top quality image capture systems, tracking of moving objects and a thermographic camera for the technical inspection of the facilities.

Thanks to the use of these drones, it has been possible to review a surface area of 10 hectares, capturing 2,900 thermal images which are now in the process of being analysed to study the behaviour of the installations and thus extend the study to the total of the 250 hectares of surface area of Endesa's three photovoltaic installations.

Q-Energy sells portfolio of 73 solar photovoltaic plants

Q-Energy announces the sale of a portfolio of regulated solar PV assets in Spain to Caisse de dépôt et placement du Québec (CDPQ), a global institutional investor.

The portfolio is made up of 73 assets with a total capacity of 216 MWp located throughout Spain. These assets produce 355,000 GWh annually, enough electricity to supply more than 115,000 homes, equivalent to the consumption of cities such as Valladolid, Alicante and Cordoba.

This investment represents the first step in CDPQ's creation of a platform in Spain, to which it expects to add new renewable assets. Following this transaction, Q-Energy will continue to take on the comprehensive management of CDPQ-owned assets, carrying out both the management and supervision of the 73 assets, as well as their operation and maintenance. The Q-Energy team already manages more than 150 renewable energy plants in Spain, Italy and Germany with a total capacity of more than 1,300 MW. On the investment side, Q-Energy has invested more than €6 billion in the sector since 2007, in solar photovoltaic, thermoelectric and wind assets.

This portfolio of assets was owned by the Q-Energy III fund, launched in 2018, which in just two years is practically invested and in the process of divestment. The closing of the transaction will be formalised over the coming months. Q-Energy has been advised in this transaction by Royal Bank of Canada and Cuatrecasas. CDPQ has been advised by BNP Paribas & Watson Farley & Williams.

Learning to measure solar irradiance

One of the variables that we must check before carrying out a photovoltaic inspection with drones is the irradiance, for this we must use a solar meter like this one shown in the video. It is a device that we can buy online and is designed to measure the value of irradiance in open environments, we should not confuse the solar irradiance meter with a light meter because the measurements and the ranges that we are going to obtain are different.

 

To measure the irradiance before carrying out an inspection of a solar plant, we must place the equipment perpendicular to the photovoltaic panel. If the value obtained is around 400 W/m2, we are within the minimum limits. The value obtained in the video is about 200 W/m2, in this case this value of solar irradiance is not suitable for carrying out the work.

 

For a successful inspection (as far as irradiance values are concerned) we must have values from 600 W/m2 as stated in the IEC TS 62446-3standard.
