About SOLARIC
Solar Intercontinental (SOLARIC) Ltd. is a Bangladeshi registered Research and Product Development Company in the field of Renewable Energy (Solar) since 2009. The company started its commercial operation in 2011 to productize the newly invented technology. With a factory established and operated by 50 employees, the company is producing thousands of Energy Efficient Solar Home Systems per month since June 2011. SOLARIC develops new and appropriate technology such as 3rd generation Solar Home System (3G-SHS) and also manufacturing the product and distributing them through its own network and partners.
Background
Energy crisis and Environmental pollutions are two of the most important issues in the world now. Bangladesh along with most of the developing countries is the victim of these crises. Bangladesh being a low income country and having least possible proven mineral resources, struggling from the beginning to meet the growing energy demands. The shortfall between the demand and supply has been sky rocketing in the last few years as the purchasing power of the rural and middle class is growing due to influx of foreign remittances. The quest for alternative source of energy and the thrust for energy conservation are the inevitable outcome of this crisis.
Realizing these facts, SOLARIC devoted itself since 2009, in the research of developing a new technology to address the need of the time, namely affordable solar solutions and Conservation of Energy. The concentration was on the applications of solar energy and making it commercially viable for domestic and commercial uses and reducing environmental pollutions. After one and half years of research, the company successfully developed “SOLAR OPTIMIZER” which dramatically improves the efficiency of Solar system and reduces the end-user cost by as much as 50%. Built-in features like Intelligent Power Tracking (IPT), Efficient Power Management and the use of innovative new appliances like Energy-saving Fan and LED Lights, the power consumption can also be reduced by 90% and thereby reduce the system cost dramatically. Based on the patented technology, SOLARIC now offers 3G-SHS which is a combination of Solar Optimizer, LED lamp, Energy efficient fan, Solar Battery and Solar Panel.

SOLARIC Projects
UISC Project: 3,208 Union Parishad
Case Study: User Experience
One of the biggest projects completed by SOLARIC so far was to install Energy Managed Solar System (EMSS) at all 3,208 union parishad offices for Bangladesh Government under Union Service and Information Center (UISC) project. These offices are grid power connected. However, SOLARIC’s objective was to ensure proper solar power back-up while grid power interrupts.
This system consists of some high technological device like solar optimizer, energy tracker, photo voltaic module and batteries. We called this system as 3G solar system where output voltage is 125V dc instead of conventional 12V dc system. This high voltage dc system creates a huge difference compare to other solar system and increase the system efficiency by reduced voltage drop.
Energy Tracker is a unique device by SOLARIC which enables to shift between Low & High power mode. For instance, users will be able to run devices like laptop, printer, scanner, webcam, led light, fans etc at low power mode (regular load).
UISC Location:Bangaon Union Parishod,
Savar, Dhaka
Entrepreneur Name: Md. Riyad Khan
Before Installation of EMSS the Entrepreneur
Mr. Riyad Khan didn’t work properly due to
load shedding and the people had suffered a
lot to get their service from UISC. People
were wait until power come back and income
of entrepreneur was poor. After this system
has been installed the entrepreneur doesn’t
wait for power supply and their income has
now increased.

Bangladesh Bank Project: 108 KWp Grid Free System
To help Bangladesh Bank’s “Green Building” initiative, SOALRIC has successfully completed one of its mega projects by installing a 108Kwp Grid free system at their head office.
The objective was to Installing Solar System with no additional battery. Due to its various disadvantages, Grid Tie was not the option they were looking for. So, SOALRIC innovated a new technology called “Grid Free” with an intelligent Delta controller.
The heart of the system is an intelligent charge control algorithm that senses the load and the Sun condition ( Irradiance) and appropriately sets the charging current from the PV so that it can support the load and also stores a small energy to cover the fluctuation of irradiance during day time. The amount of energy harnessed from the PV per day is equal to the energy consumed per day. As a result, a small size energy buffer is required to store the momentary excess. The PV is over-sized in a way such that it can offer significant amount of energy even at low irradiance (morning and afternoon) to elongate the backup time. It is a significantly cheaper trade-off as the price of the battery is 6 times more than the PV and it also poses health hazard and space constrain.
Some of the key attributes are below
Component Attributes
PV 108 Kwp
Battery No extra battery
Load 50 Kw
Operating hours 6 hours/day
Rooftop Space 80 sqft/Kwp
PV panels at the roof of BB

Patent of products
The department of Patent, Design and Trademarks of the Government of the Peoples Republic of
Bangladesh has granted three patents to the company, title of which with brief descriptions is given
below:
1. Improved Solar Home System Key features: 3G-SHS is a complete solar home system that removes the
limitations of traditional SHS (1G and 2G) by converting the low voltage (12V)
into higher standard voltage (120V or 220V). The conversion technique is DC-DC
to ensure high energy efficiency. The output voltage is highly regulated (less than
0.1% over variation of load and input level) so that LED lamp can be used directly
driven by the converter without any additional driver for the LED lamp. The choice
of output voltage in the 3G-SHS, within the range of 85V-265V (universal voltage
range) makes it possible to operate any standard energy efficient appliance such
as color TV (LCD or LED), CFL lamp (220V, AC), Laptop, energy efficient fan etc..
Standard wiring, unlimited distance, ability to charge mobile phone without any
additional adaptor etc. are the key benefits of using 3G-SHS in the off-grid areas.
2. Standalone Prepaid DC Energy Meter Key Features: SPDC-EMS is a complete energy metering system that removes
the need to have any remote communication using telephone, mobile phone,
internet etc. such that the system can operate independently in the area where it
is used. This unique system has been developed with three distinct features in
mind such as Standalone operation, Simple and low cost prepayment system,
Wide range of DC voltage as the source. The embodiment of the entire system has
been realized by developing 2 pieces of equipment known as Code generator and
DC prepaid meter. Code generator accepts input such as the amount of pre-
payment, meter ID etc. from the operator manually and generates a unique code
which is different every time and can be recognized by the DC prepaid meter only
which matches the meter ID. The DC pre-paid meter can be operated from a wide
range of DC voltage (12V to 600V) and can accept the unique code generated by
the Code generator and updates the available balance upon successful
authentication. Both devices are used in the same geographical location (usually
Intelligent Delta Charge Controller
16 www.solaricglobal.com
1-2 km) and does not need any other communication outside the location for
successful pre-payment and metering operation.
3. A highly energy efficient modularized DC – DC converter with a
small controller for turning ON the appropriate no. Of modules
by sensing the load
Key Features: is a highly energy efficient DC-DC conversion system where the
self-consumption and the conversion loss have been reduced dramatically by
using a number of smaller DC-DC converter modules in parallel and controlling
them using a smart controller which turns ON and OFF the appropriate number of
modules by sensing the load. Many of these converters can be used in parallel to
further increase the load capacity of the system. This unique system has been
developed with three distinct application nature in mind such as Efficient energy
conversion regardless of the load condition, 24 hour operation with variable load
and low cost easy scalability of the system.
And … The Future
One of the main differences between SOLARIC and other solar technology developer companies is
that SOLARIC always keeps one question at the back of mind – “How this innovation will improve
the quality of human life?” Reason behind that is the intention and commitment towards the
underprivileged community who always thrived for a better life. Many a times the company had to
choose the harder path, as it never compromises with quality, safety and service issues. The
dedication and hard work has already paying its dividend as SOLARIC was able to gain the trust of
the Government of Bangladesh within very short time by successful completion of various projects.
The reputation has even crossed the border of the country. Quite a few reputed and successful
organizations have put faith on SOLARIC products and enthusiastic to work together. These are big
achievements for a company started up not so long ago. However, SOLARIC believes that it is only
the beginning of the big, bright future lies ahead.
