Advanced Photovoltaic Parks Design and Engineering

Ecowat JSCo. established 1998 by George Tonchev. ECOWAT JSCo is a leading Bulgarian company providing all steps of wind energy and solar power engineering. ECOWAT JSCo is wholly owned by its directors and has no equity stake in any wind turbine or photovoltaic manufacturers or wind energy plant - its advice is independent and impartial. ECOWAT JSCo counts among his clients local and foreign wind energy investors and developers. Some 70% of ECOWAT turnover is generated outside the Bulgaria. Some Bulgarian municipalities are also our clients.

Our solar and wind projects activities includes micro and macro sitting, environmental vision, feasibility studies, investment evaluations, technical pre-design, infrastructure and energy output analysis, geotechnical site investigations, foundation, grid connection and other civil and electrical construction activities in the fields of wind and solar power plants.

We bring customers over 11 years in-depth experience and knowledge of Solar Energy Audit and photovoltaic power system design under own brand Solextra^TM .Design services  combines mechanical, structural, and electrical engineering expertise with best-of-breed computer-aided design automation tools and industry-leading system layouts to deliver high-performing solar energy systems. For a selective solar energy audit we developed and used an own 5 dimension measurement method and related device.

ECOWAT JSCo has competence of the whole spectrum of wind turbine design and related know-how based on the inventions of our ECOWAT Team

ECOWAT JSCo experience includes outline design and network connection studies and execution of wind and solar photovoltaic projects. We can assist in the tendering process by writing specifications, short listing contractors, and evaluating tenders. Often ECOWAT JSCo has been involved in this work for the entire renewable energy projects, either directly for developers or as part of a technical due-diligence review for Investors and financing organizations.

In recognition of the need for strategic planning to ensure successful implementation of local, regional and national renewable energy projects and programmers, A key objective of most strategic studies is the effective targeting of investment to maximize leverage or returns.

Ecowat JSCo. is focused on electrical and photovoltaic system design and assembling of PV power plants - solar parks. We can provide code compliant electrical design for grid-tied or stand-alone PV systems, as well as other forms of distributed generation. We provide customers with today’s most advanced solution for maximizing both solar energy production and financial project savings on large-scale solar projects.

The new invented Wind-PV synergy energy system exploits a passive ground based PV-modules supporting structure as an wind accelerator directed accelerated wind to wind turbine JET blades. This invention is applicable as an upgrade of the turbines operating in Wind Farms, as well. The hybrid systems, generally, is better energy source from energy-system point of view. Another invention related to low cost energy storage system is applicable to all renewable power plants.

Low cost reflector augmented PV module

PROBLEM TO BE SOLVED:
To increase yearly electricity yield of PV modules in solar parks and building integrated PV installation by  providing a photovoltaic reflection device for solar power generation for acquiring much more power generation quantity than a conventional manner by reflecting sunlight on the concave reflector of rays of light to intensively emit the sunlight to a solar cell module.

SOLUTION:
A photovoltaic reflector is rotated by an angle of rotation so that sun can come to the extension of the reflector of the rays of light installed on a solar battery module, and mobile leg is moved by an computer controlled elevation unit at the bottom part of the module to adjust the angle of the reflector so that sunlight reflected on the reflector can be emitted to a solar cell module.

ADVANTAGIES:
Low cost upgrade of existing solar PV parks and other PV installations aimed an enhancement of yearly electricity yield of non tracking PV modules by movable controlled reflector without any changes of existing module configurations and inclination.

A spatial design based on advanced software aimed land and space saving low cost PV park layout.

The best technical solution based on "power output/PV module size" maximization.

APPLICATIONS:
For development of new solar PV projects aimed bigger electricity yield of the inclined non tracking modules and upgrading of existing solar PV parks and other PV installations. A video of patented Solar PV reflector augmented system see at:   www.youtube.com/user/miscbeep#p/a/u/0/XE-mOgND07I . Shown on road power plants is using for charging the battery of electric cars and plug-in hybrids, as well.

Photovoltaic / Wind hybrid system

More common applications of Distributed Power Generation are Photovoltaic /Wind hybrid system. Natural resource as wind and sun very differ site to site. The first priority of our project is  to maximize both PV and Solar power output for every site. We are using a complete set of match calculation method for optimal of a PV/wind hybrid system. In this method, more accurate mathematic models for characterizing components as well as models for estimating the available natural resources are adopted; in order to find the optimum configuration which generate power at the minimum cost. Because wind blows in wide range of velocity is very important the right choice of the wind turbine type. A video of an advanced wind turbine for hybrid applications is presented here    

We have developed an advanced planning models integrated into a GIS-computational tool, based on a detailed differential solar irradiation measurement (according to a patented 5D solar measurement method) in an interaction with Geographic and Solar statistic Information Systems, for evaluating solar energy resources. Our aim is to select the most suitable photovoltaic technology, and calculating the cost associated with its installation and the economic value of the generated electric energy. These design and planning models allow for obtaining economic competitive projects among different PV technologies, including inverter configurations, power distribution network expansion costs, electric power demands and PV installations in different geographical locations. The tool has been applied successfully in Bulgaria and Greece and can be easily adapted to any other region in the world. The computer results can currently also be remotely accessed by intranet and they will be available on the Internet in the future too. The new method and tool can be applied to real life studies that are useful for technicians involved in the construction of new buildings, engineering design offices, electric utilities, public national or regional energy agencies, economic development agencies, public and private environmental protection agencies and regional government authorities.
