“Create electricity with solar radiation”
A solar photovoltaic installation permits to produce electricity by using the solar radiation. The necessary components are the photovoltaic modules and (On-Grid) inverter. However, concerning the intended use, some elements can be added such as: chargers (regulators) solar (MPPT / PWM), battery (gel, AGM, OPZS, Lithium, Redox…), supply inverter (or switch), Off-grid inverter, Smart-Grid inverter…
Between 2006 and 2011, incitation measures were set in place by the majority of European states, for boosting the photovoltaic grid connected market (sale electricity generate by the solar installation). Since 2011, electricity purchase price are constantly decreasing, therefore the photovoltaic market is currently deeply restructurted around the new self-consumption / self-production model.
“Using the wind to create 100% renewable electricity”
A wind-turbine creates electricity with kinetic energy. There are two types of wind generators: vertical axis wind-turbines (Darrieus / Savonius / Maglev) and those with horizontal axis. Different kinds of configurations are possible:
“On-Grid” installations (injection to the grid)
“Off-Grid” installations (with battery, for remote sites)
Smart-Grid installations (coupling On-Grid / Off-Grid)
Realizing an estimation of the production potential of wind-turbine systems, involves consideration of multiple complex settings: On site climatology, ground roughness, topography, and environment.
IMEX-CGI provides instrumentation studies (mast measurement / telescopic / datalogger / data acquisition station) define the on site’s potential. By considering: records, production curves of wind-turbine and some physic laws (Weibull…), IMEX-CGI defines the envisaged production per wind generator.
“Ensure almost the totality of hot water needs thanks to solar”
A solar thermal installation heats the water with solar radiation. This water can be used in order to cover a part or the totality of the sanitarian hot water (Individual solar water heater )or/and in heating CSS (combined solar system). Some solar thermal systems can generate steam and can be used for industrials applications. In most of the case, an installation is composed of solar sensors and accumulators which can be equipped with one or multiple exchangers. There are different types of solar sensors technologies: the “plans” sensors and “tubes” (caloduc / upipe). Each one of these technologies present some advantages and also some inconveniences according to the type of applications.
IMEX-CGI, advices its customers by sizing project and by guiding them through the most appropriate technology.
