Self-consumption solutions

Energy efficiency technology Self-consumption solutions

The drop in the cost of solar photovoltaic improvement of the quality of electrical energy installations, coupled with the increased and exploiting the renewable resources cost of electrical energy borne by end that produce it, has designed solutions that consumers in recent years, has accelerated integrate energy distributed in the electrical the arrival of the so-called grid parity in many grid with instantaneous and time-delayed regions throughout the world. CIRCUTOR, by self-consumption applications for industrial establishing synergies between knowledge applications, service facilities and even of the measurement, management and residential buildings

A solution adapted to each need

Each consumer has a different demand curve, as well as specific situation in terms of access to the grid. To this end, CIRCUTOR has designed different solutions that adapt to each situation, offering optimum management of solar resources, optimising efficiency, simplifying management processes and achieving the highest possible cost savings.

The solutions offered fall into two categories, based on the time relationship established between solar production and the consumption of electricity in each case: yyInstantaneous or direct self- consumption, without storage yyTime-delayed self-consumption with storage yyInstallations isolated from the grid yyInstallations with DC coupling to the grid yyInstallations with AC coupling to the grid Instantaneous self-consumption Time-delayed self-consumption with control over the energy with energy storage injected into the grid It is necessary in buildings where the main consumption of Ideal for buildings with significant daytime electricity electricity is during night-time or low solar radiation hours. consumption. CDP (Dynamic Power Control) controllers adjust the maximum production power of photovoltaic Installations isolated from the electrical network inverters to that being consumed in the building at all times. It can supply energy to places that do not have good Therefore, we can guarantee that, for example, surplus access to the electrical distribution lines, catering for the energy is not injected into the grid or that the power fraction energy needs of different consumption types (residential, allowed by the specific laws of each country is injected into agriculture, tourism, etc.) The solutions isolated from the the grid. grid offer high quality electric supply for any common use of energy, such as lighting, household appliances, power In many countries, this type of installation allows the use units, etc., both in single and three-phase applications. of the photovoltaic system as an inherent element of the building's internal electrical network, becoming an energy Hybrid solar-diesel generation can improve the performance saving element and not an energy generation system that of the installation and minimise the use of the support requires the capacity to discharge energy into the grid to generating set, depending on the consumption features which it is connected. and intelligent management of storage and demand.

Installations with DC coupling to the grid Buildings connected to the grid can improve their degree of solar self-supply by installing a battery between the building and grid that stores surplus energy during periods of high insolation for its future consumption.

In these systems, controlling the battery charge plays a crucial role, since it manages the flows of energy between all elements in an installation. Therefore, the system can self-consume energy directly during the day, storing daytime surplus energy in the battery and, finally, reduce the consumption of grid energy during periods of low insolation by discharging the battery.

Instantaneous self-consumption with control over the energy injected into the grid Installations with AC coupling to the grid Buildings connected to the grid that already have a photovoltaic generation system installed can transfer part of the solar energy production for its consumption during periods of low insolation.

In these systems, controlling the battery charge can reduce or even eliminate surplus daytime energy transferred to the grid and reduce the power peaks required by the grid by injecting the power stored in the storage system.

CDP CB Combiner Box for protecting and managing solar installations

Description

Photovoltaic systems are composed of various separate DC circuits that must be combined in a single circuit before DC is transformed into AC, in order to use this AC power and inject it into the electrical network or use it for internal consumption of a dwelling or building. The Combiner boxes are used for such purposes. These connection cabinets group the different strings connected to the photovoltaic panels.

CIRCUTOR's CDP CB combiner boxes group all DC and AC electrical protection elements required, so that the user can have everything in a single cabinet.

In addition to the protection elements, the products of the CDP CB range come with a CDP-0, which guarantees that the user can manage zero injection into the electrical network, as well as a CVM-MINI power analyzer for measuring the electrical consumption.

The CDP CB combiner boxes feature a web server, through which the user can connect to monitor both the installation's consumption and generation of electricity.

The CDP CB range of combiner boxes has been designed to complement the range of self-consumption kits with zero injection to the grid. COMBINER BOX
