Is Solar-Grid All we need ? @ a big question

A country development entirely depends on the on-growing development of technology specially energy sectors. Energy sectors are the foundation of the entire technology system, no energy no technology.

To develop a strong energy system in the country government usually takes a lot of initiatives to overcome scarcity in the energy sectors and in this frame the picture of solar technology shines with the bright smile.

developing countries like Bangladesh or other Asian or African countries are deprived of sufficient amount of energy sources. These countries can change their future only if they are smart enough to utilize natural sources with 100% efficiency. And what I mean by efficiency here, this means input of a country which includes labor and money and other resources.If an country can manage the input resources efficiently then  losses will be reduced and prosperity can be higher (InsaAllah)..

What is Solar -grid: This is  a power plant system of generating electricity  which includes solar technology (Solar Panels / Inverter/ Battery ). This is not a huge power giving grid , it is basically a mini or micro grid system where the output power is under 10MW. In Bangladesh it varies from 100KW~150KW most which is very small for locality. and it has long list of troubles which I mean authentic troubles.Let me list  it for you, 

• High in Investment and calculate in millions without government or foreign subsidy cannot be done .
• It takes a lot of space like a football field or something.
• High labor input and hard to manage human resource.
• High transportation cost for transferring heavy elements (Solar Panel/ Inverters).
• Need more work to set up whole system and needs long time.
• If anything happens in the solar-grid it is hard to find out and harder fixing it. 
• The line losses are high and for sure payment is high i.e electric bill.
• Very dangerous high voltage DC system.
• We can build more Small home Solar system if we use lost power in the solar -grid.
• The connections are complicated and friction loss is higher.
• There is extra cost for software installation and running it.
• Any kind of failure in grid can shut down entire load system.
• The electric charge is higher then the conventional.
• The connection cost from the grid to user takes additional charge and also takes metering charge.
• Normal people has less access to the technology. 
• It makes rich people rich and poor people poor.

 Solution : Solution to this all problems is build small but efficient solar systems which is different for different load system..

•  100W~2KW solar system for house hold , mosque, single shops.
•  2KW~20KW solar system for School, Colleges , Universities, Shopping Malls.
•  20KW~ above solar system for Small or medium Industries.

Note :   Small initiatives are the best for saving efficiency in the resources and make everyone part of the system , so no matter poor or rich can both can access and enjoy this growing technology..Ameen. :)

How you know how much electric load in your house ??

What is Load : In electrical concept the power amount of  electric devices is called Load.  

Let me clarify for you.

If in your house you have a room in which you have a 70W of electric fan and  30W of CFL light and a Computer which consumes 120W, the total load of your room is summation of each power of each load.

That means Load of our room is  = (70+30+120 ) W = 220W total. (1st Room).

Now if you have another room which has a table lamp of 30W, a Table fan of 55W and a CRT Televison of 140W, then the Load of that second room is = (30+55+140) W = 225W total ( 2nd Room).

So if your house has only two rooms and nothing else then total Load of your house is = ( 1st+2nd) Room Load = (220+225)W = 445W of Total Load...But if your house has kitchen or Bathroom or other rooms then you have to calculate them manually then finally sum every loads of individual rooms.This is that simple.

note :  The necessity of knowing your house load information is very crucial and important.One should know his/her house load information for controlling the bills and the payment for electricity...

This is a very simple but very important knowledge that everyone should have...

Hope this post helps you(Jajakallahu Khair) 

   

Is Solar Energy Can Solve Your monthly Bill (100%)

There could be a question in the minds of every users, is solar energy can erase all electric bill. The answer is yes.

Solar Energy system can be your life time guarantee for living without paying electric bills.

How I am guaranteeing this ??

If you want to follow what I am saying below then it might be :

Process :

• Establish a Solar System for your house big enough that can give 24 hours supply.
• Use mostly DC appliances instead of AC appliances  as much as possible.

Reason why this process will help :

• First you need to know how your bill is coming from your electrical device... use my bill calculator..
• Then find out are those DC or AC devices, you will see AC devices are costing you the most.
• AC devices are costing you most because typically they are high in power rating and more the power rating then more the payment.
• Generally  most of the electrical devices in the house are AC .
• And generally DC electrical devices consume less power then AC electrical devices, why? because AC devices are high in voltage rating but less in current rating but in our houses most important devices are mostly current driven. Let me give an  example to you , if   you have a rice cooker or a tea maker or a toaster in your house then if you check you will find those are all high power( 500W-1800W)  products and if you go deep in this matter you will find this power consume ratings are high because of high voltage and lower current ratings. Let me explain more the working principle of any heat creating devices which are rice cooker or toaster has a coil inside of it and that is made of a metal called Nichrom which has a high resistivity and that creates high heat for higher current but due to less current rating in AC source AC products become less efficient.
• DC products always consume lower power than AC products with the same efficiency and actually this is the main reason of higher electric bill in AC devices.
• AC system consists of high power loss because of its frequency which generally 50/60Hz, but in DC system frequency is 0Hz which makes a better power efficient system.

Note : As you will learn how to reduce your home loads your bill will start to go down. using DC devices instead of AC Devices  as much as possible will reduce monthly loads of your house and that will cut price from the installation of you solar home system which is a first time payment and later all free..

Hope I make you understood (God Bless U)

DC or AC Products

In our household  there are two types of electrical appliances, i) DC ii) AC.

In some electronics device that could be both but  basically driving current as  ac or dc current...

In world today in every house or every store or in every office most of electrical products are AC built in system...because the generation of electricity is coming from synchronous generators alias alternators which are AC generators, so there is no other 

choice for manufacturers to develop but AC electrical appliances could be AC bulbs, fans or freezer...

Now you could ask me why not DC power are generated from the electricity manufacturing company at the first place, the answer is they are not rookies.It takes much more cost in some case impossible to generate huge DC power from energy conversion technology.

Yes in this case Solar Technology is the best because this is the only source where you can expect huge DC power comparing to other but still you can't compare with alternator technology which is built in AC.

Here everything put on a question which product should be manufacture, which is more efficient and available and cost effective. 

The answer is not that easy and I will tell you why, as because about 98% of the world electricity generation is AC power and other 1~2 % is DC power, so by general condition every manufacturer company will decide to produce AC products but where DC product is the most efficient and cost effective. 

Benefits of DC products :

• It consumes the least power ( Even DC Iron, TV, Cooker are less than 200W which is amazing, you can't find in AC but same capacity products) 
•  It is the best for household system because it is low in voltage and more safer.
• Electricity Savers  (the best)
• Compare DC products to AC product you will find approximately 20~300W differences with the same capacity product which is outstanding. 
• 1 AC Light = 4~10 DC lights,   1 AC TV = 5 DC TV, 1 AC Cooker = 3~4 DC Cooker, here you can imagine how much electric bill you can save (My God).
•  More important we can use solar power to run this DC product and which is amazing because solar power is free just you need first installation cost , and it is totally off-grid which means no load-sheeding.
•  May be one day if every home, office or store install a solar system of 500W with a good storage battery bank probably 50% of the government power generation will be saved for the future.
• And thanks to God that we have technology of flexible solar panels which we can use anywhere with DC products like , Solar Bag, Solar power Bank, Solar Mobiles etc.
• In house DC products can be more efficient if you have solar tables and solar products (Solar table lamp) which use indoor light to generate DC power (Amazing).

 More or less every day we need DC and AC product but in future may be if possible there will be only DC appliances in every home and why not just think about the money that DC products gives over AC products.

May be one day we don't need to pay electric bill anymore or it could be  like 20~50Tk/month... Just a dream (InsaAllah).

Which light Bulb is the best @ Incandescent ,CFL, LED (Review)

  Incandescent ,CFL, LED (Review)

The most Important electrical appliance in the house is the electric light bulb,and we need it everyday even though other devices are not available because darkness is scary.......Literally...

Trust me monthly bill mostly covered with lighting cost, and they can steal your money :( . because you are using it  almost  day & night and that makes a hard earned man worried & wicked....

In  market places there are a lot of product on lighting, and trust me market places are getting weirder everyday, they always find something new and can give you a craving for buying it..

• But Typically in house we mostly find three types of light bulbs : i) Incandescent light ii) CFL iii) LED

Let put them in the test :

Incandescent Light :

This lights are based on heating up by electricity where high temperature causes glowing light comes out of it . In Incandescent light a filament is used called Tungsten Filament and because of its high resistivity  high current creates heat and light..

•  This light bulbs are filled up with inert gas ( Argon, Nitrogen etc) which prevent the Tungsten Filament from evaporated and extends its lifetime...
• Comparing other lighting bulbs it comes out very cheap and easy to get anywhere..
• But it uses the higher power supply then any other energy saving bulbs with the same lumen capacity.
• This is the device which is responsible for your deadly electric bill.......Beware...
• It has the least life span then other lighting bulbs...

CFL lights :

This light is the compact form of traditional Florescence Tube Lights. and it works with the same principle...that is why it is called Compact Florescence Light.

• CFL light has integrated electronic ballast inside it which make it compact..
• This light is filled up with Mercury Vapor which is the main source of light, when voltage is applied between the electrodes and electron make mercury exited which create a UV radiation in the tube which later turns into normal light when it passes through the phosphor coating (Spiral Part)..
• These lights are way energy saving then the Incandescent lights , it consumes less power then the Incandescent lights for the same lumen  that why these are called Energy saving lights...
•  It shows four-five times more life -time span comparing Incandescent lights, and that is why it market price is very high but worth it for long time.. 

LED Lights : 

LED bulbs is made of LED lights in a fixture which is very efficient comparing to any other bulbs, even better then CFL bulbs.. The construction of this light containing Heat-sinker which absorbs heat from the circuit and keep it cool, Driver circuit which deliver required current and voltage form input to output, and LED panel which contain a string of series and parallel LED lights..

• Led light are the most efficient Light bulbs, better than any florescence and incandescent light bulb..
• Very Lower wattage consumption comparing both CFL & Incandescent, 4~6 time CFL & 10~20times Incandescent.
• Price is higher then both comparing CFL & Incandescent....But worth it.
• Life Span is very high about 30000Hours ~50000Hours,
• Comes with high warranty 1~3 years..
• Comes with different colors.

Comparison : 

 You can easily can identify which has the best performance by the reading the given statistics.

 LED & CFL is far more better than the Incandescent light bulbs....

 

Lumen/Watt means the bulb capacity of radiating lights using power, for per watt power the best lumen given by the LED lights which is way better then CFL & Incandescent light....

Note : If you compare and assemble your all data and statistics then you will realize LED bulbs are the best at it performance and longevity, please buy LED bulbs if they are available in your locality, but is that means CFL & Incandescent light are useless, answer is no both lights are good in some points like incandescent bulb is not only source of light but also a source of heat, it has some great use in incubators or where warm heat is need and CFL has closer performance compared to LED bulbs and cheaper in price, so if your locality has no dealer of LED bulbs then go with the CFL......

Flexible Solar Panel

Flexible Solar Panel : 

One of the outstanding innovation and great development of solar technology..

Flexible Solar Panels are the same as the conventional solar panels which are built in frames. 

Flexible Solar Panel built just like other solar panel with solar cell, but because of it's flexibility it extends the uses of application. 

The efficiency , voltage , currents are exactly same here as we know in framed solar panels.

It is also categorized in three 1) Mono 2) poly and 3) Thin Film.. 

Mono & Poly Flexible Solar Panels used mostly bigger applications like power grid, or vehicular construction  but Thin Film Flexible Solar panels are versatile and diverse in small application..

Just as you and I know that Solar Panels and cells are only uses on the roof or on the pole or in mini-grids application, but the reality is the more you research the more you discover new applications.

Benefits :

•  It can be use most of the places where conventional framed Solar Panel can't be use.
• It is lighter in weight then other Solar Panels, so easier to carry and that makes it water better  portable.
• The shape and size is variable, and this make a lot of easier for installation..
• You can take it anywhere you want like picnic, or camping...
• You can use it many places like cars, boats, house windows, or many other applications..
• Flexible Solar Panel are using for different decorative house hold systems which is diversifying the indoor application of solar panel which I will explain broadly in Solar Indoor Outdoor Decor section.
• Various outdoor application can be designed by flexible solar panels where you can't use framed solar panels..like curved tables or Solar trees or street led chairs.
•  
   
  
  
  
  

  
  
  Because of its flexibility you just can install anywhere, and the thin solar cell make its contribution here the most. As the Thin Solar cell can be design very small they are very handy with this type of flexibility technology which make the solar application much more versatile..

•  Flexible Solar Panel can be found very smaller power rating with very small size... https://www.seeedstudio.com/2V-1W-Thin-film-Flexible-Solar-Panel-p-1856.html, https://www.seeedstudio.com/5W-CIGS-Solar-Cloth-p-2455.html
•  We can use various way for different application using series and parallel of this flexible solar panels specially Indoor applications..

This is an awesome product, you can use it for diverse application by your self, I will show many other ways of using flexible solar panels in  upcoming Solar Indoor Outdoor Decor section..
