About Me
- Hi, I am currently a Student at Michigan Tech. pursuing Masters in Power System (Electrical Engineering). Have worked in the EPC industry for approximately 3.5 years and also had a short stint with lower level management (Supply Chain Analysis) while working with a major Cosmetic Brand. Currently working on my Photovoltaic System project. Short film making and acting take my time if not engineering or at least something related to engineering.
- Here's my Linkedin Profile - https://www.linkedin.com/in/anurag-yadav-5b622b68
Interested In
- Career wise in Solar Power, Project Management, Engineering Procuring and Construction.
- Interested in being able to support society be self-sustaining. Its fun to think how Utilities might get supported if domestic PV units becomes a mainstream practice. I strongly believe that small communities should try to sustain on their own power/ energy rather than fully being dependent on the Grid thus help minimize transmission congestion and energy cost and of course its Eco friendly too.
- Eager to learn new things and find striking a random conversation with strangers very interesting.

Literature Review
Bificial PV System in Aichi Airport-Site Demonstrative Research Plant for a New Energy Power Generation
- System Designed for Solar Power generation along with usage as Noise barriers.
- 3 types of solar PV used- 1) Multi Crytalline, 2) Amorphous & 3) Single Crystalline (Bi-FAcial)
- Apart from the combination of above, different types of fuel cells were also used
- Rear Side of the Bi-facial panels were approx 21% less efficient at site readings in terms of Pmax
Technical Guidance for Evaluating Selected Solar Technologies on Airports by Federal Aviation Administration:[2]
T. Uematsu, K. Tsutsui, Y. Yazawa, T. Warabisako, I. Araki, T. Joge, Novel applications for flat-plate modules utilizing bifacial PV cells, in: 12th International Photovoltaic Science and Engineering Conference, 2001, Jeju, Korea, pp. 805–808
The paper review early methods of developing bi-facial PV modules.
- 12.5X12.5 cm SOG wafers were used for manufacturing B^3 cells
- Bi-facial PV require long minority carrier lifetime to achieve high efficiency in the rare. (carrier lifetime - carrier lifetime is defined as the average time it takes for a minority carrier to recombine. The energy released due to recombination can be either thermal, thereby heating up the panel)
- The generated power of a bifacial module did not depend much on the facing direction. When the front and rear efficiencies were the same, the generated power was almost the same as that of a monofacial module tilted at 301 facing south, and it did not show decrease when facing other directions.
The first advantage is that the generated power is not sensitive to the facing direction of the module, which reduces the limitations on PV module installation sites. The second is that a bifacial module installed normal to the ground can generate equal or larger power than a monofacial module tilted at 301, which greatly reduces the area required for installing PV modules.
Colli, A.; Zaaiman, W.J., Maximum-Power-Based PV Performance Validation Method: Application to Single-Axis Tracking and Fixed-Tilt c-Si Systems in the Italian Alpine Region," in Photovoltaics, IEEE Journal of , vol.2, no.4, pp.555-563, Oct. 2012 doi: 10.1109/JPHOTOV.2012.2203794
The paper discusses and validate the performance evaluation through a methodology based on the effective maximum power of the PV modules.
- Three types of crystals were analyzed - i)polycrystalline silicon, ii)high-efficiency monocrystalline silicon, and iii)hybrid monocrystalline silicon
- Two types of support structure were also used, i) fixed frame at 30 degrees and ii) single axis tracker
- The irradiance detected by the tracker plane is higher than that monitored on the fixed support plane
- Inverter readings are used for collecting system data, therefore its important to check system tolerance for both, DC and AC measurements.
- The solar constant is the average amount of energy striking one square meter (perpendicular to the suns’ rays) each second at the top of the earths’ atmosphere. The satellite measured solar constant is 1366 W/m2. Of this energy reaching the top of the atmosphere as much as 70% can be absorbed & reflected by the atmosphere. Solar insolation is the amount of energy received by the sun at the earths’ surface. On a clear day ~1000 W/m2 reaches a surface perpendicular to the incoming radiation. This energy varies due to the angle of the incoming radiation and again cloud cover.[4]
Can we help reduce Temperature related stress on Airline hangers by using rooftop PV or worsen it further. Can Rooftop PV be helpful as an alternate roof structure or will it add on to the weight stress and building costs? reduces heating and cooling costs by insulating the roof, and extends roof life
Ricardo Rüther, Priscila Braun, Energetic contribution potential of building-integrated photovoltaics on airports in warm climates, Solar Energy, Volume 83, Issue 10, October 2009, Pages 1923-1931, ISSN 0038-092X
This paper discuss exactly the note point mentioned in the previously reviewed paper. Florianopolis International Airport in Brazil used Building Integrated PV to counter two problems at the same time.
- 1st being the air conditioning cost reduction - being a hot maritime location, air conditioning placed heavy loads in terms of power demand. This was done by using PV to facades leading to providing extra insulation and better cooling on roofs.
- 2nd is the supply of power from Solar. Being a location with solar radiation irranging from 1500 up to 1650kWh/m^2/year with small seasonal variations, this made up for an ideal location for solar PV.
- Simulation and sample studies performed support of using solar PV at airport system but 3 of the major troubles faced like Glare, Radio interference and airspace breach were neither incorporated nor discussed.

- Its important to keep in mind that most of the airports have conventional distribution grids and unidirectional power flow. Hence, it needs to be considered while upgrading protection schemes as well. As, the inclusion of solar PV will make the grid bi-directional in power flow.
