Water Generator Project Update

Scope and Requirements The objective of this project is to provide water for drinking and cooking in places where access to water is limited. A dehumidifier is operated using solar panels and rechargeable batteries to condense water vapor in the atmosphere. In this phase of testing, our intent is to establish a methodology assess the performance of the system, as well as put a data acquisition system in place to enable remote monitoring over time.

Hardware Used

Axpert KS 1 KVA Inverter: The inverter used in our project can be connected to different monitoring and control systems via serial port. It uses MPPT to manage solar panel output, and provides pure sine wave AC output using DC input from the batteries.
Laptop
RS-232 to USB cable
RS-232(male) to RJ-45 cable
Belin BL-830E 330W 30 liter 220V dehumidifier
Five solar panels of 150W each from Mono Select China
Two 12V rechargeable Gel batteries from Narada. Each battery is 100Ah capacity
Circuit breakers
Mounting stands 14G adjustable
7mm to 10mm wire – thickest wire is between charge controller output and battery input

The picture of some of the hardware is shown below

RS 232 male to Cat6 connector for inverter

RS 232 female to USB cable plugs into laptop

System Connections The five solar panels are connected in series, and the batteries are also connected in series. The schematic is shown below:

Power Consumption The power consumption of the dehumidifier is shown in the table below. Clearly, the power during startup of compressor will be highest, and will fall a bit during steady-state operation. The particular dehumidifier cuts-off at 40% relative humidity.

Orphanage Solar Update

Objective: The objective of the project was to install a solar panel solution to a load shedding stricken orphanage in the less developed areas of Karachi,

The first step of the process was to survey several orphanages and decide which one was the most suitable for installation of A Solar Panel solution. The three orphanages that were visited were as follows:

1. Al Mustafa Academy

1. SHED foundation

Edhi Centre

Al-Mustafa Academy:

Address:

Plot No. 82, Sector 40-C, No. 1, Noorani Turning, Karachi, Pakistan

Observations:

“Al-Mustafa My home Orphanage” is situated near Korangi no.1, a thickly less privileged area of Karachi. It occupies a wide area. All the area is surrounded by boundary walls and there are three gates for the entrance.

There is a guard available on the main for security purposes. It also consists of a Medical Centre, a girl’s college and an orphanage. In my observation the place is safe for the installation of our solar power project. It can be place at the top of the children hostel.

Here is the picture of the Khadija Girls College which is under construction in the boundary:

POWER OUTAGE:

Power outage has been a serious problems in the areas of city like Orangi and Korangi etc.

There has been a power outage of more than 8 hours in the day time. The people are suffering from these problems. Al-Mustafa Orphanage has a small generator only covering the needs of an Orphanage. They don’t even have some facility for the clinic which is available at low cost for the poor.

I also consider it safe for our installation. Also the authorities are more friendly and co-operative than any other organization.

SHED FOUNDATION:

Address:

SHED Homes Complex & Hospital, Beside Aiwan-e-Sanaat o Tijarat Hospital.

1/2-A، Karachi, Pakistan

Observations:

Here’s a picture of plan of SHED Foundation which helps us to understand the structure and details:

We can do our installation at the top of the building of children hostel. All the area is surrounded huge boundary walls and there is a guard available 24 hours at SHED main gate. It is located in the North of Karachi in a thickly populated area near Nagan Chowrangi.

Power Outage:

Power outage has been a serious problems in the major areas of city but in SHED Foundation the power outage problem is controlled by a stand-by generator available. This generator covers the School, mosque, mentally ill building section and senior citizen shelter. It has a huge power output. There has been a power outage of more than 4-5 hours in the day time. The people are suffering from these problems.

Edhi Centre:

Address:

R5J7+45, Landhi Rd, Korangi 5, Karachi, Sindh

Unfortunately the staff at Edhi Centre were not willing to cooperate with us therefore there isn’t any more information to provide on this location

Area Analysis:

Load Analysis:

The visit that took place by the team to both the places have well-constructed infrastructure with quite of load including both of necessity and luxury which leads to the prior decision of the load capacity that Sawayra would agree to provide with. The following details contain the no of load in respective organizations.

After a through comparison of both the respective organizations it was decided that Al Mustafa was more suitable for Solar Panel Installation hence it was selected for this project.

Load auditing:

After the project location was selected it was decided that an energy audit was to be performed. For this four vendors were contacted.

1. Greenewables

1. Pak Solar Services

1. Premier Energy

Zi Solar

Out of the four contacted only Greenewables visited Al Mustafa. Sir Jawwad was also present for this visit and surveyed the location as well. After a complete tour and survey they deduced that:

The Process of industrial energy auditing would be too expensive for a load this simplistic.

Alternative Load Auditing methods:

In order to audit without using the expensive industrial method, the following three devices were listed and compared:

1. Emon PI

1. Iota Watt

Smart PI 2.0

SMART-PI 2.0	EMON PI	IOTA WATT
It consists of three terminals for connecting output of Current Transformers.	It consists of only two terminals for connecting Current Transformers.	It monitors up to 14 circuits.
It is very small in size	It is bigger than smart-pi 2.0	The size is not so big
It can be imported from Russia	It can be imported from UK	–
We can analyze or see it’s circuit	We haven’t seen or studied about its circuit components	It’s based on the ESP8266 IoT platform using MCP3208 12 bit ADCs to sample voltage and current at high sample rates.
It is an open source with all codes available.	It is an open source with all codes available.	It is an open source/open hardware project.
The Smart Pi have less reviews or it is belong to a single person who have made it	It has greater reviews and belongs to an organization	No reviews available on the iota watt website
We can buy the pre-installed things with complete assembling.	We can also buy it in the same way. But we cannot buy separate components	We can buy the devices and other components are available in Pakistan
We can buy separate components. E.g.: only board, only casing, only Raspberry pi 3	We cannot buy separate components	We just need to buy the main board and other components are available in Pakistan
We’ve to learn both for setup but it do not requires so deep understanding.	We’ve to learn it but it also requires to understand some features linking to its Wi-Fi adapters or power source.	Flexible configurations

It can gives information on the web display.	It gives information on its little 16×2 LCD Display. Also web interface is available but not too much friendly	The Iota Watt supports automatic over the air (OTA) firmware updates. Where all the data can be excessed through Wi-Fi on phones
Overall finally, it requires some knowledge to have final working setup.	It is easy to assemble, do not requires great knowledge. But it is limited to very few quantities	It is very easy to assemble.
Wi-Fi adapter is not present but built in Wi-Fi works well.	Built in Wi-Fi + a Wi-Fi adapter is also available	It has built in Wi-Fi

After consideration it was decided that Iota Watt was the most suitable device for load auditing. However before the Iota Watt could be installed at Al Mustafa, two things needed to be done. Get more equipment to undertake the auditing of this scale and test the Iota Watt in Pakistan as so far it had only been tested in South Korea by Sir Jawwad.

Procurement of Equipment:

In order to install the Iota Watt at Al Mustafa for load auditing certain equipment had to be purchased. For this I and Syed Umaid Ahmed went to Saddar in May to purchase said equipment.

Testing of Iota Watt:

Before the Iota Watt could be installed at Al Mustafa, it was required to be tested to see how it performs on Pakistan’s Power System. It was installed at Sir Jawwad’s home in Pakistan under his supervision by me and Syed Umaid Ahmed.
