Annex 4
Testing Laboratories
1. The establishment of a credible laboratory is far more challenging than the acquisition of the
test equipment itself. The mission recognizes that establishment of these laboratories in Bangladesh is
particularly challenging, but also notes that the proposals for the laboratories, and the considerable
resources allocated, were intended to overcome the many constraints of having to conduct tests outside
of the country. These laboratories are intended to be facilities of excellence both within Bangladesh,
and globally.
BUET Testing Laboratory
2. The mission visited the laboratory on 18th October 2016, and met with BUET team led by Prof
Ziaur Kahn, as follow-up to the 17th April 2016 meeting. Discussion resulted in the following
observations.
Laboratory itself is established within the Department of Electrical and Electronic Engineering.
It is physically located on 6th floor in a large open area with requisite space available. It will
be managed by an organized team with functional responsibilities allocated within the
laboratory structure which will facilitate IEC 17025 accreditation.
Initial work for establishment of the laboratory dates back to late 2012 with MoU signed in late
2013. Test equipment procurements took place in late 2014 in several lots. Most of the
equipment was delivered in by April 2016.
As of October 2016, all of the test equipment that was previously delayed at Dhaka customs is
now delivered. All essential equipment is one site, including the PV module testing equipment,
battery testing equipment, and light dome.
Now that the test equipment is on site, the immediate delays in commissioning the equipment
are related to physical infrastructure.
o A large PV testing darkroom must be constructed within the laboratory for the flash
testers – this is not yet done as it requires BUET management approval to relocate a
doorway.
o Light dome requires to be housed within a controlled and dust-free environment. It
would be to same specification as the PV darkroom. This is not yet built.
o Battery testing: BUET proposes to demolish the existing concrete water bath for
temperature control – due to space constraints. The dust from this demolition will
certainly be problematic for the two “dust-free” darkrooms unless this demolition is
completed first and the dust allowed to settle fully.
o Therefore it seems that better planning and co-ordination is needed to ensure that the
test equipment on site is not damaged by dust during these ongoing construction
stages, and to expedite laboratory operation.
o Only after the completion of the building infrastructure will final commission and
training be done. Is it intended that these will be complete by January 2017, with
training shortly thereafter.
The physical infrastructure challenges are not the only delays. After commissioning and before
the laboratory can be fully operational, the laboratory organization staffing, management,
quality assurance approach, need to be finalized. It became clear during discussion that the
proposed test procedures and test methods are not yet finalized and that requisite documents
are not yet with the laboratory.
Accreditation of the laboratory to IEC 17025 will only be possible after some years of
successful operation. It was also mentioned full accreditation is likely not possible via local
20
accreditation agent due to the specific nature of the laboratory tests, and that this would need to
be done using international agents, further adding to time and costs.
In order to reduce impact of further delays, it is necessary to approach the challenges in a
parallel manner. Specifically, IDCOL laboratory consultant should begin his work
immediately, prepare the laboratory management and all test procedure documents for
distribution to the BUET staff, and require laboratory to be set-up before December 2016.
In terms of changes to the original proposals, BUET has already taken consideration of :
o LED lumen maintenance, ascertained by aging LED under controlled conditions to
100hr, 1,000hr and up to 4,000hr to assess quality. The lab had not provided for LED
aging. The lab is adopting procedures and facilities for LED aging at ambient
temperatures, at no additional cost. TSC standards for LED are already updated to
include lumen maintenance requirements, and Lighting Global/ IEC 62257-9-5
procedures are already being considered. LM79, LM80, LM25 procedures and
methods may also be of interest.
o Charge controller and inverter testing will be performed using existing laboratory test
and measurement equipment of BUET. An additional requirement is a temperature
controlled chamber to measure performance, set-points, efficiencies and stability under
elevated ambient temperature conditions. This has not been provided for under the
procurement and is a constraint. IEC test procedures have been shared with BUET by
from other sources.
IDCOL Technical Monitoring Facility and Equipment
3. A meeting was held at IDCOL with Md. Wahidur Rahman on 20th October 2016, with the
following observations. This facility is intended to strengthen IDCOL’s technical ability for monitoring
SHS, solar mini-grid and solar irrigation, biogas slurry testing, ICS, and water quality.
IDCOL facility will be located at another space rented by IDCOL near its head office.
Construction alterations were designed by IDCOL consultant and works are underway to ready
the facility, due for completion in May, 2017.
Equipment procurement for the facility has been undertaken for three lots:
o Lot 1: Successful procurement, with equipment delivery by 28 June 2016 for
monitoring SHS, solar mini-grid and solar irrigation.
o Lot 2: Unsuccessful initial bid. Rebid under a “shopping” procurement process, with
equipment expected to be installed by end November 2016, for equipment for biogas,
slurry and water quality testing.
o Lot 3: Successful procurement, with equipment delivered by 31 June 2016 and training
has been given for improved cookstove and emission measuring equipment.
Equipment and laboratory is expected to be fully operational by December 2016.
IDCOL has appointed a test facility manager to commence on March 2017.
United International University – DC Test Laboratory
4. A visit was conducted to the laboratory on 17th October 2016, and met with UIU team led by
Prof. Rezwan Kahn, and Mr Shahriar Chowdhury, as follow-up to the 17th April 2016 visit. Discussion
resulted in the following observations.
The Laboratory is now established within the UIU, physically located on new building on roof
level, with large PV arrays on the new laboratory roof space.
21
The concept for this facility dates back to early 2012, and the final proposals and agreements
and MoU were signed in late 2014. The building construction was completed in late 2015.
The unique facility is for promotion of DC mini-grids. The laboratory is intended to answer the
questions on whether and how DC mini grids can be implemented, and to compare performance
of DC mini grids with the existing AC mini grids. Facility is designed for assessment and
demonstration of performance, safety, and fine-tuning of both AC and DC mini-grids and their
key components. Primarily, it is intended to address the perceived safety and performance
arguments, together with lack of standards, which are barriers to large scale DC mini-grid and
micro-grid roll-out.
The hardware and components of the AC mini-grid are fully installed and operational as of
April 2016. These include 3 x 48V battery banks, SMA 3 phase bi-directional inverters and
AC coupled inverters with switch gear and safety features.
The facility is intended to be switchable between DC and AC mini-grids. The DC mini-grid
change-over as designed is not complete. Development work is still ongoing on DC mini-grid
development and demonstration. It is not yet possible to demonstrate a DC mini-grid with the
same performance and safety features as the current AC mini-grid installed (refer to boxes 3
and 4 shared in October 2014).
As of October 2016, UIU has submitted a draft final report on the progress of DC mini-grid
component development, which is suited for micro-grid level performance. It seems that this
research work has not utilized at all the specialized mini-grid equipment installed under
laboratory, and might have been possible in an existing electrical or electronics laboratory. Key
questions that must be answered to allow promotion and financing of DC mini-grids, and the
raison d'etre for the facility itself, remain largely unfulfilled. The mission conducted follow-up
meeting with the UIU laboratory director to clarity expectations.
There are other uses and benefits of for the DC/AC mini-grid laboratory:
o The laboratory can be also used to resolve AC mini-grid technical issues arising, under
controlled environment, including:
addressing perceived performance issues relating to AC-coupled component
interactions; including phase-shift fold-back power limiting of grid-tie
inverters and DC charge current limiting of bi-directional inverters using the
same SMA equipment deployed at 95% Bangladesh PV mini-grids.
resolution of remote data-logging issues and remote monitoring deficiencies,
evident at most mini-grids installed under IDCOL programme, including
measurement of parameters that are not currently captured (battery in/out
energy; AC feeder power / energy; diesel engine power/energy).
o General testing of mini-grid add-ons before approval and installation in the field:
testing of data-logging system for non-SMA equipment or for DC mini-grids.
enhancement of central data-capture and data viewers to collect all the
necessary information from all remote mini-grid data-loggers, using SCADA
database or SMA OPC server.
UIU laboratory is intended for the purpose of identifying these types of problems inverter under
controlled environment. Therefore the mission requests the following:
o The AC mini-grid configuration implemented so far is based on minimal 1-day
autonomy battery sizing, and thus requires on-demand operation of the hybrid diesel
generator for reliable plant functioning. Mini-grid sponsors were turning off the diesel
permanently to save money – but these challenges now appear resolved through
awareness raising to the need for generator on-demand operation. However, there are
suggestions that it remains to be proven that the overall solar plant is operating at
22
optimal design efficiency, and is not relying on costly generator operation to sustain
energy supply.
o Further, it has been demonstrated that the remote monitoring systems installed as-is as
inadequate for performing even basic energy balance, or addressing challenges
remotely. Specific needs are in the box 1 below.
o Mission requested UIU in April 2016 to conduct a simple depletion and charge test
using their laboratory to bench mark the AC system charge performance. This has not
been done. The specific procedure is in the box 2 below.

Box 2: IDCOL mini-grids – AC coupled array charging efficiency
o It has been suggested that the AC-coupled PV arrays in the existing IDCOL mini-
grids may not be charging the batteries at maximum efficiency via the AC-DC bi-
directional inverters supplied, in all cases being SMA Sunny Island (SI) units6.
o The problem, when present, is understood to manifest in and be related to frequency
shift curtailment of the PV-AC inverter by the SI. The result would be that the PV
array is not operating near its maximum power point, which would not ensure
maximum charge to the battery when needed. If this were the case, it has significant
implications for all IDCOL mini-grids, which use SI, and are now all moving
towards 100% AC coupled arrays, with the DC coupled arrays being discontinued.
o The issue, when arising, may be related to firmware, or settings within the inverters,
or transient interactions, configuration issues, or SMA design issues. Or the problem
may not be present within certain SMA batches or serial numbers.
In any case, IDCOL needs to know if there are set-up, design, configuration, or
warranty problems, or not
UIU as owners engineer needs to know the same.
UIU as AC/DC mini-grid experts should be in position to take a lead role in this
investigation.
o The issue is difficult to assess on site under uncontrolled conditions.
o Since this laboratory is specifically and fully equipped and mandated to assess and
make these comparisons, it should be done with urgency.
o The basic procedure to be conducted while measuring all electrical inputs is:
Deplete battery to a state that it will absorb the full array power (say 50% DoD),
Charge battery via PV only, with no grid feed supply.
Measure or asses the actual array MPP
Measure array actual output (Vop, Iop)
Assess whether AC grid tie SMA STP is curtailing the array, or is operating at
MPP
Assess whether SI is curtailing STP AC grid inverter
Under what conditions does this occur / replicate
Quantify the impact, in Ah delivered to battery, to system energy performance,
and to battery life.
Solution – what is the remedy?
Is AC coupled array adequate under these conditions?
o While it is understood that these are Lenders Engineers issues, it is in the interests
of the Owners Engineer to resolve these.
6 Essentially, the issue relates to historical problems with compatibility between SMA STP and Sunny Island as a
result of firmware issues, limiting bi-di battery charger performance of the AC coupled arrays. The problem, once
identified, is known to be very difficult to correct, and requires an SMA technician to attend to it as the most cost effective
solution.

Research and Development (R&D) on Renewable Energy in Bangladesh
1. USD1 million was set aside out of the USD6 million of technical assistance fund under the
original credit (Cr. 5158) of the REREDII project to support R&D initiatives. IDCOL invited
Expression of Interest (EoI) from national entities/individuals interested to conduct R&D activities for
improvement of existing renewable energy technologies as well as for development of new renewable
energy solutions for Bangladesh. Till date 13 projects have been awarded to different research teams to
develop different R&D facilities.
2. IDCOL has extended grant support to different research teams of United International
University (UIU) for four different projects. One is to develop a hybrid mini cold storage and to study
the financial feasibility of establishing cold storage while another team is working on the development
of solar PV panel energized boats. Both the projects are mainly designed for the rural remote areas of
the country. Third team is developing a smart solar irrigation monitoring system suitable in the context
of the country.
3. Under the fourth project, UIU and Solshare have developed a robust and affordable Community
based DC Nanogrid for combined household and Productive use. This project has received worldwide
recognition and acclamation from international bodies i.e. 2016 Intersolar Award – “Outstanding Solar
Project” and 2016 UN Momentum for Change Award as the first Bangladeshi institution.
4. BRAC University has developed 15 solar powered electric rickshaw-vans (human hauler,
ambulance, cargo). Torque sensor paddle was used to minimize initial inrush current.
5. A team led by a professor from Dhaka University of Engineering & Technology (DUET) is
conducting research to design & develop a thermal energy storage system using proper Phase Changing
Material (PCM) i.e. water to avoid expensive battery backup system of conventional solar cold storage.
6. Another project to facilitate source segregation and safe disposal of wastes in Bagherhat
municipality was awarded to Practical Action. The objective of this task is to develop a Public-Private-
Partnership (PPP) model for a community based biogas plant considering the municipal solid waste
(MSW). The project activities include design and construction of a treatment plant, supply and storage
of biogas for cooking and running machines etc.
7. Bangladesh Atomic Energy Commission is working to produce dye-sensitized solar cell using
local technology and resources.
8. To find a sustainable alternative source of electricity ‘Solar E Technology’ has developed a
facility having solar powered battery charging booths for electric vehicles i.e. easy bike, electric
rickshaw and electric car. Under a separate project Solar E Technology is also developing a cost
effective and sustainable solar hybrid cold storage systems for rural areas to preserve fresh produce,
fresh milk & medicines.
9. IDCOL extended grant support to Bangladesh University of Engineering & Technology
(BUET) to develop a R&D facility to synthesize and characterize mutiferroic nanoparticles to enhance
their photo-catalytic activity and to produce hydrogen fuel by photo-catalytic decomposition of water.
10. IDCOL has awarded two separate projects to BAU and B. Tech Construction & Consulting to
analyze cow, buffalo dung and microbial community, analyze microbial dynamics during anaerobic
digestion of animal dung, pH and temperature dynamics to increase the efficiency of biogas production
and augmentation of cow dung with other organic feedstock. Both the organizations have the same
objective, although their approach to the problem is different.

Annex 7
Household Energy Component
1. Improved Cook Stoves
(i) ICS Implementation Progress: The program was started with IWA Tier-1 efficiency7 ICS
dissemination which were available at the time. R&D on the development of higher tier of the
low cost ICS was started early in the project which has now succeeded in developing Tier-II
and higher specification ICS. From July, 2016 Tier-1 ICS are no longer disseminated. With this
transition higher efficiency ICS, the dissemination dropped drastically in July (Fig.1) but rate
has started recovering. It is likely that the rate will stabilize at around 40,000 per month. With
this pace of implementation, the project target of dissemination of one million ICS is likely to
be reached before June, 2017 which is 18 months before the planned date of end 2018. In order
to keep the program going until the end of 2018 which is the project closing date, more
resources will be needed for the incentives for POs.
Fig. 1: Rate of ICS installation per month (Transition to Tier-II ICS lead to drastic fall in
July, 2016)
(ii) R&D on Higher Efficiency (Tier) ICS
The ICS program was initially started using concrete ICS of Tier-1 performance level for which designs
were available. In order to improve the performance levels of the concrete ICS, a R&D contract was
signed with to improve the efficiency and emission of concrete ICS and as well as development of
metallic body ICS with IWA Tier II& higher level performance. BUET has now completed the
assignment and 6 models of better performance concrete ICS have been produced. The comparison of
the performance of these models with base models originally adopted by IDCOL are shown in table-1.
The emission levels are also lower for these improved models. These model are being progressively
introduced for dissemination as reported above.
7 IWA (International Workshop Agreement) is an interim standards for ICS agreed in 2012 which is to be
followed by a future ISO standard.
