Low cost reflector augmented PV module - patent pending
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.
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 hereWe 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.
Our R&D team has developed number of innovative photovoltaic and thermal solar solution that described on these pages.
Spatially for solar parks, we are developed solar reflector system for conventional PV-array that doubling the energy yield of solar parks.

Note:
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 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.
Ecological advantages of building integrated PV-systems
Photovoltaic (PV) based electricity
production is pollution-free at the local as well as the global level, it
does not emit greenhouse gases, it does not dip into finite fossil fuel
resources and it can be easily integrated into the urban environment, close
to major consumption needs. However, prior to producing electricity,
manufacturing and installing PV systems and later on dismantling and
recycling them require spending a certain amount of energy, which must be
“reimbursed” before PV can be considered as renewable and clean. The purpose
of this report is to provide clear and well-documented answers to
politicians, decision-makers and the general public about what PV can and
cannot achieve in terms of renewable, clean energy production and
environmental protection. The conclusion of this study is that, depending on
the location, rooftop-mounted PV systems produce the amount of energy so as
to recover their energy content from manufacturing and recycling in the
range of 1.6 to 3.3 years and produce during their energy production period
or service life between 17.9 and 8 times their initial energy content. Once
they have reimbursed their initial energy input, rooftop-mounted PV systems
can avoid, during their
lifetime, the emission of up to 40 tons of CO2 depending on their
location and on the local electricity mix available.
Results for PV facades are logically slightly worse than for roof-top PV systems since they produce less energy for the same installed power. They produce the amount of energy to recover their energy content from manufacturing and recycling in the range of 2,7 to 4,7 years and produce during their service life between 10,1 and 5,4 times their initial energy content. Their contribution to CO2 emissions mitigation can be up to 23 tons of CO2 per kWp installed.
