Photovoltaic - grid-connected systems
With more than 30 MWp installed PV systems, EST is one of the leading companies in Germany in terms of planning, procurement, installation and maintenance of roof integrated PV systems.
Our activities extend in Italy, Spain, Greece, Austria, Czech Republic, USA and Switzerland where we plan in the next 2 years 40 MWp of projects.
Photovoltaic – stand alone systems / off-grid systems
EST has extensive experience in Photovoltaic stand alone systems, EST carried out many projects as subcontractor for Siemens Germany in the field of power supply for telecommunication in Sudan, Cameroon, Nigeria, Senegal, Lybia etc.
EST provides solutions for all kinds of systems that need a stand alone power supply ranging from 10W to any power limit needed.
Photovoltaic – hybrid systems with photovoltaic, wind generators and diesel generators
Photovoltaic – hybrid systems with photovoltaic, wind generators and diesel generators are the solutions that combine wind, sun and diesel generators for supply of electric power at any range.
By using photovoltaic and wind turbines you can provide electric power and with diesel generators α 100% availability is assured for applications like telecommunication stations, hospitals, offices etc.
Photovoltaic – UPS and emergency power supply
Photovoltaic – UPS and emergency power supply by means of photovoltaic and diesel generators UPS (Uninterruptible Power Supply) is essential for applications with 100 % power stability and secured uninterrupted power supply at any time, even in cases of power failure or power cut.
UPS systems are absolutely necessary for telecommunications equipment, computers, backup of power for hospital operating rooms.
UPS-systems can use any source of power supply like wind, sun, oil, supported by batteries to provide 100 % uninterrupted power.
By using photovoltaic as main source, the units are almost maintenance-free, have very low maintenance costs and are designed to last more than 20 years
Photovoltaic – solar home systems
EST provides designed Photovoltaic appliances which are easy to install for local electricians and trained personnel.
All components are made and designed as “plug & play”, which is easy to install and works almost maintenance-free.
It is for providing light in rural areas with no or unstable electricity.
Back up for homes, schools and especially for refrigeration of medicine in hospitals and pharmacies.
Obstruction lights / tower warning lights
For telecommunication towers and tall buildings
For telecommunication towers and tall buildings
With photovoltaic and batteries it is possible to light up parks and streets without connection to public power supply.
PV lighting systems do not need cabling, earth movement or connection to public power.
They are easily installed, they are independent from power-cuts, from public power, and they are not charged with electricity bills.
