Indepement Systems

It all began in 1839 when the French physicist Edmund Bequirel (father of Nobel laureate Antoine Henri, for the discovery of radioactivity) first discovered the photovoltaic phenomenon. That is, the direct conversion of solar energy into electricity by means of photovoltaic cells (or otherwise called solar cells or solar cells).

Almost 177 years later, the development has made the stand-alone photovoltaic power supply system the first choice for buildings and facilities. This is because it produces electricity from the sun (photovoltaic) without necessarily being connected to the public electricity grid by providing energy autonomy. Such a system can also work in conjunction with another alternative energy source that can be renewable (eg wind turbine) or conventional (eg power generation) and is then characterized as a hybrid system.


These systems are able to store excess electricity through the batteries so that it can also be used during periods of no sunshine (evening hours, cloudy).
The size of an autonomous photovoltaic power generation system depends on the demands of the electrical loads and the autonomy demanded.
The autonomous photovoltaic electrification systems are ideal for permanent and summer residences (caravans, cottages), small businesses, boats, hotels, agricultural applications (solar irrigation pumps, greenhouses), but also for tourist businesses (camps, rooms to let).
Also, autonomous power systems are an optimal alternative (in the event of power failure) to ensure autonomy for some basic appliances (refrigerator, lighting, television, internet, alarm, medical equipment, etc.)


An integrated stand-alone system consists of:

– Photovoltaic panels

– Charge regulator

– Power converter

– Accumulators

It is necessary to study correctly

One of the most critical points before implementing an autonomous system is the proper study that ensures the security and functionality of the system. A very important role is played by the quality of the materials offered, so never two systems have the same values ​​(two batteries with the same capacity and the same trend may differ dramatically for example in the number of life cycles).
Our years of experience in autonomous photovoltaic power systems combined with our specialized scientific and technical staff guarantees the choice of the optimal solution for the independent power supply you need at the best prices.

Why choose a photovoltaic system?


The fall in the prices of photovoltaic panels combined with the increase in electricity costs and other charges, resulting from the connection with PPC, make the investment sustainable and efficient. The return on investment is ejected if the public network is remote and the initial interconnection cost is high.


Renewable Energy Sources are the world’s first choice, which is imposed by the European Union’s legislation on environmental protection.


Modern autonomous photovoltaics are far from the systems of previous decades. The choice of ECO//SUN, which will carry out the right study and optimally install the best quality materials, will guarantee a reliable result without unexpected power outages and technical failures.


Choosing a company with the experience and know-how of ECO//SUN guarantees the safe operation of the system and user protection (switches, DC and AC fuses, anti-electro-relay relays, etc.) in any possible error or emergency.


An autonomous photovoltaic system operates completely silently and can not be compared to the noisy liquid fuel generators, which do not fit perfectly with the tranquility that the interested person desires in his country home, listening to the tranquility and tranquility of the majestic Greek nature.


An autonomous electrification system can be transferred to another building or expanded at any time, recommending a lining that never comes into play.

Minimum maintenance

The maintenance of a qualitative ECO//SUN stand-alone system is minimal and does not compare to the frequency and maintenance cost of a liquid fuel generator.

It is placed everywhere

An autonomous system can be installed everywhere, in any location and in any building, as opposed to the public network that can not or at least requires a great deal of cost to drain at any point.
