Bulgarian B2B network. Bulgarian territory is very sunny and is an attractive place for development of Solar PV Parks. The best feed-in-tariff.

Bulgarian territory is very sunny and is an attractive place for development of Solar PV Parks. The agricultural land now is not expensive. But the main attraction is the Preferential conditions for stimulating photovoltaic development in Bulgaria include but not limited to special government guaranteed sell prices of power generating by PV (feed-in-tariff as minima) for 25 years as follows:

420 euro per MWh generated by PV up to 5 kWp power installed.
386 euro per MWh generated by PV as high as 5 kWp power installed.

Typical sun irradiation on Bulgarian territory varies from 1 300 up to 1 500 kWh/m² per year.

Spatially for solar parks, we are developed number of advanced solution to increase energy yield. E.g. - solar reflector system for conventional PV-array that doubling the energy yield of solar parks. This system allows to reduce significantly pay-back period of the solar park investment and to increase the internal rate of return.

Simple pay-back period of the PV investment in Bulgaria is 5-6 years.

Internal rate or return (IRR) is about 17%

The cost of PV solar power generated is about 0.1 Euro per kWh

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.

Photovoltaic Parks Design and Engineering

Ecowat JSCo. established 1998 by George Tonchev. At same year ECOWAT JSCo is joined to B 2 B ^TM network.

ECOWAT JSCo is 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.
