DUELA POWER SOLUTION

Editor’s note: welcome to another great time of awakening the giant in you! Today, we have yet another addition to the duelapowersolution writing fold today, his name is – Olasunkanmi Emmanuel. Sit back and get inspired by his very first piece and remember to check his bio at the end of the piece. Also, kindly drop your comments so we know you read this piece.

Happy Reading 

The modern definition of the subject of this post has made the need to write the post even more compelling. Many have missed it as a result of their inability to distinguish between these two words. Let’s consider these two words and compare them?

The word success as defined by Wikipedia as “The achievement of something planned, desired or attempted”. While on the other hand, perfection can be described as the condition, state or quality of being free or as free as possible from all possible flaws or defects.

These two words if put in contrast can be said to contradict each other as it will only mean that there would be no need to attempt, plan or desire something, it is already there! You already posses the ability to make your desire come to life. You can become whatever you desire without going through any stress. Everything is just there for you! At the snap of your finger, everything come to be! Mind you, this is not true! The world is not meant for perfect people. Sure you agree with me?

Perfection is not a common virtue common among men; in fact, no man can claim to be perfect. Why is it then confused for success? Perfection is a trade-mark only associate with God. He made man with perfection but man lost it as soon as he fell to the serpent (Devil) ever since, he has strived and will continue to strive to attain perfection. Little wonder why they say we all aim towards perfection! Never heard anyone say that he/she has achieved it! Man will always aim to achieve this but the best we can record can only be success! The best a man can achieve is to be successful in his/her attempt in accomplishing a set goal or target.

The misconception surrounding the subject of this post has led a lot of people astray. Men with goals and aspirations have lost it as a result of their inability to fully understand what success really mean. No wonder scriptures said “my people perish because of lack of wisdom.”

An attempt just as earlier mentioned to accomplish a particular goal or target has already put you enroute the path to success. Your ability to be consistent, dogged and determined to accomplish that particular goal will confirm you as being successful though someone somewhere else with a similar goal might go even a step further. That point when you feel you have achieved success might just be a stage for another person towards accomplishing that similar goal or even a part of the process. In anyway, that point when you gain personal satisfaction after an attempt or fulfillment of a desired goal or target is when you can say you have achieved success.

Get it right, a proper definition of your goal will give you a proper insight as to when success is achieved. Therefore, it is very important when setting a goal that you  attach a purpose to it and properly define your objective, thoughts like “what do I intend to achieve?” “Is it really necessary for me to do this”? “What will happen if I don’t do it?” should always be considered when setting a goal.

The lesson that should be taken from this post is simple: don’t work with someone else’s clock (timing). Clearly define and be purposeful when setting a goal or target. At that point when you feel you are satisfied with what you have achieved, then you can congratulate yourself and be glad you achieved success. Only a not well defined goal will lead to confusion not even perfection as it was intended.

Now that you know, I believe you can retrace your steps if you have missed it and get that goal right. Change your mind set about success and tap into the real meaning. Aim to be successful.

Remember, success doesn’t mean perfection; you can always try again!

If You Are Building A House And You Want To Incorporate Solar Energy, Read This

Hello I am Olayinka a Business Developer for Africa Sustainable Energy.
As electricity bills and price of fuel increase around the country, solar panels are increasingly being installed by homeowners wishing to take advantage of a system that produces greener energy and insulates them from rising energy prices. 

If you are building your house and you have not factored solar energy into your budget then you need to go back to your drawing board. No one can run away from electricity needs, because it drives the economy. Only smart individuals understand that they can spend less on solar energy in the long run than using fossil generators.

Solar energy needs no introduction, with the abundance of sun in Nigeria; we still are not harnessing the energy. With the current price of fuel, every smart individual knows that solar energy is the way forward.
The major challenge of solar energy in Nigeria is the cost but what people have failed to factor is that theses system has a life span of 25-30 years. It has no moving parts, it needs no maintenance.

When building a new home, you have the opportunity to build it right from the get-go, saving yourself thousands of naira in utility bills over the decades (as well as offsetting the associated fossil fuel emissions).

High efficiency appliances make the most of the energy they consume. Electricity is appealing because you can generate it for free with solar panels on your roof.

However, the amount of electricity generated at a particular site depends on how much of the sun's energy reaches it. Thus, PV systems function most efficiently in the northern part of the country, which receives the greatest amount of solar energy.
Before selecting system components and sizing a PV system for an existing home, you should evaluate your energy consumption patterns and try to reduce your home's electricity use. You can start by performing a load analysis with the help of a good installer.

By understanding your "energy habits" and becoming more energy efficient, you can reduce the size of the PV system you'll need, lowering both your capital and operating costs.
If you're designing a new home, you should work with the builder and the solar professional to incorporate your PV system into your whole-house system design -- an approach for building an energy-efficient home.

There are 3 types of Solar Energy Installation

1 Back-Up System
Back-Up Installation are essential, UPS that provides uninterrupted electricity when the power from PHCN goes off. They mainly consist of Inverter and batteries. The batteries sustain power for a give number of hours at a time before recharge.
A Back-Up installation can later be upgraded, by adding solar panels.

Who needs this Installation?
This system of installation is suitable for people who have at least 10 hours of electricity per day. If you are not sure of the number of hours, you can still install now and later upgrade. The most important thing is you have started.

2 Stand alone system
A Stand alone system is a system solely relying on solar energy and does not require PHCN for charging its own system. It isn't connected to a electricity distribution grid operated by a utility.
When considering Stand alone system, you should hire an expert installer to know the energy audit of your appliance, positioning of solar arrays and number of panels required to let your system run for 24 hours otherwise your batteries may not be getting charged. 

Who needs this Installation?
This system of installation is suitable for people who want some part of their appliance in their home or all of their appliances be totally independent of National grid.

3 Hybrid Systems
In a hybrid Solar Installation, there is always electricity round the clock because more than one source is required and available for battery charging. For example, there is the presence of at least two of the following: 

• PHCN
• Solar array
• Wind energy
• Fuel/Diesel Generator 

Hybrid Installation provides the highest form of power efficiency and availability.

Who needs this Installation?
This system of installation is suitable for people who cant afford the stand alone installation, so the number of solar array is reduced reduc to let other source cover up for the time charging.

There are 3 factors everyone needs to consider before coming up with a budget.
I Energy Load
2 Number of Hours the Battery can sustain without charging
3 Price of each system Component 

I have prepared a simple quote that describes the design and cost analyst for a 1.2kva, 2kva and 3.5kva stand alone solar generator stand alone system.
In the quote I will be sending out, you get the:

1 The Total wattage of all your house appliance for 1.2kva & 2kva System
2 Current price of every component, that makes up the solar generator.
3 1.2kva Quote for back up and Stand alone system
4 2kva Quote for back up and Stand alone system
5 We also compare the price of the solar installation to the cost of same 1.2kva fuel/ Diesel generator for a period of 1 year.

        STEP BY STEP WAYS  TO INSTALL  SOLAR RENEWABLE ENERGY

This instructable will show you everything you need to put together a pretty good sized electric solar panel system. Things you will need: 






Supplies: 
Solar panels 
Charge controller 
Battery charger 
2 AWG cable 
At least one 12 Volt marine deep cycle battery 
Mechanical lugs 
1 power inverter 
1 Rubbermaid tote or other container 
1 battery charger 

Tools: 

Cable cutters 
Red electrical tape 
Screwdriver 
Drill 
Crescent Wrench 


Gather supplies and lets get started. 

Step 2: Place batteries in container

Once the batteries are fully charged, place them in the container and. Make sure all the positive (+) terminals are on one side and negative (-) on the other. Once in place, measure from terminal to terminal to make the jumpers.

Step 3: Creating the jumpers

Next, we want to connect the batteries in parallel. To do this, Make some jumpers out of 2 AWG cable.

Note: Make sure to size your jumpers for your system. If you want to use a larger inverter you will need to use larger cable. 1200 Watts/12 Volts = 100 Amps. Depending on where you look, 2 AWG cable is good for around 100 Amps. If you want to run say, a 2400 watt inverter, you should use 2 cables per jumper.

Measure between terminals and cut cable to length. Then add the mechanical lugs. Since the battery terminals were a bit bigger than the holes in the lugs I bought I drilled them out to fit. 

Step 4: Preparing the lid

Now, add some holes in the lid to run the wires for the charge controller and the inverter. I wanted the charge controller outside so it was visible. You could just as easily put it inside the container for a more concealed look.

Step 5: Connecting the charge controller and inverter to the batteries.

Next we connect the charge controller and the inverter to the batteries. You will want to make sure the inverter is turned off and the charge controller is not connected to the solar panels yet.

Step 6: Final set up and test.

It should all be wired together. All that is left is to connect the charge controller to the solar panels and turn the inverter on and check to see that it works.

                                                     How to Design Solar PV System

What is solar PV system?

Solar photovoltaic system or Solar power system is one of renewable energy system which uses PV modules to convert sunlight into electricity. The electricity generated can be either stored or used directly, fed back into grid line or combined with one or more other electricity generators or more renewable energy source. Solar PV system is very reliable and clean source of electricity that can suit a wide range of applications such as residence, industry, agriculture, livestock, etc. 

Major system components

Solar PV system includes different components that should be selected according to your system type, site location and applications. The major components for solar PV system are solar charge controller, inverter, battery bank, auxiliary energy sources and loads (appliances).
  •   PV module – converts sunlight into DC electricity.
  •   Solar charge controller – regulates the voltage and current coming from the PV panels going to
      battery and prevents battery overcharging and prolongs the battery life.
  •   Inverter – converts DC output of PV panels or wind turbine into a clean AC current for AC
      appliances or fed back into grid line.
  •   Battery – stores energy for supplying to electrical appliances when there is a demand.
  •   Load – is electrical appliances that connected to solar PV system such as lights, radio, TV, computer,
      refrigerator, etc.
  •   Auxiliary energy sources - is diesel generator or other renewable energy sources.

Solar PV system sizing

1. Determine power consumption demands

The first step in designing a solar PV system is to find out the total power and energy consumption of all loads that need to be supplied by the solar PV system as follows:

     1.1 Calculate total Watt-hours per day for each appliance used.
           Add the Watt-hours needed for all appliances together to get the total Watt-hours per day which
           must be delivered to the appliances.

     1.2 Calculate total Watt-hours per day needed from the PV modules.
            Multiply the total appliances Watt-hours per day times 1.3 (the energy lost in the system) to get
            the total Watt-hours per day which must be provided by the panels.
2. Size the PV modules

Different size of PV modules will produce different amount of power. To find out the sizing of PV module, the total peak watt produced needs. The peak watt (Wp) produced depends on size of the PV module and climate of site location. We have to consider “panel generation factor” which is different in each site location. For Thailand, the panel generation factor is 3.43. To determine the sizing of PV modules, calculate as follows:

     2.1 Calculate the total Watt-peak rating needed for PV modules
           Divide the total Watt-hours per day needed from the PV modules (from item 1.2) by 3.43 to get   
           the total Watt-peak rating needed for the PV panels needed to operate the appliances.

     2.2 Calculate the number of PV panels for the system
           Divide the answer obtained in item 2.1 by the rated output Watt-peak of the PV modules available
           to you. Increase any fractional part of result to the next highest full number and that will be the
           number of PV modules required.

Result of the calculation is the minimum number of PV panels. If more PV modules are installed, the system will perform better and battery life will be improved. If fewer PV modules are used, the system may not work at all during cloudy periods and battery life will be shortened.

3. Inverter sizing

An inverter is used in the system where AC power output is needed. The input rating of the inverter should never be lower than the total watt of appliances. The inverter must have the same nominal voltage as your battery.

For stand-alone systems, the inverter must be large enough to handle the total amount of Watts you will be using at one time. The inverter size should be 25-30% bigger than total Watts of appliances. In case of appliance type is motor or compressor then inverter size should be minimum 3 times the capacity of those appliances and must be added to the inverter capacity to handle surge current during starting.

For grid tie systems or grid connected systems, the input rating of the inverter should be same as PV array rating to allow for safe and efficient operation.

4. Battery sizing

The battery type recommended for using in solar PV system is deep cycle battery. Deep cycle battery is specifically designed for to be discharged to low energy level and rapid recharged or cycle charged and discharged day after day for years. The battery should be large enough to store sufficient energy to operate the appliances at night and cloudy days. To find out the size of battery, calculate as follows:

     4.1 Calculate total Watt-hours per day used by appliances.
     4.2 Divide the total Watt-hours per day used by 0.85 for battery loss.
     4.3 Divide the answer obtained in item 4.2 by 0.6 for depth of discharge.
     4.4 Divide the answer obtained in item 4.3 by the nominal battery voltage.
     4.5 Multiply the answer obtained in item 4.4 with days of autonomy (the number of days that you
           need the system to operate when there is no power produced by PV panels) to get the required
           Ampere-hour capacity of deep-cycle battery.

Battery Capacity (Ah) = Total Watt-hours per day used by appliances x Days of autonomy
(0.85 x 0.6 x nominal battery voltage)

5. Solar charge controller sizing

The solar charge controller is typically rated against Amperage and Voltage capacities. Select the solar charge controller to match the voltage of PV array and batteries and then identify which type of solar charge controller is right for your application. Make sure that solar charge controller has enough capacity to handle the current from PV array.

For the series charge controller type, the sizing of controller depends on the total PV input current which is delivered to the controller and also depends on PV panel configuration (series or parallel configuration).

According to standard practice, the sizing of solar charge controller is to take the short circuit current (Isc) of the PV array, and multiply it by 1.3

Solar charge controller rating = Total short circuit current of PV array x 1.3

Remark: For MPPT charge controller sizing will be different. (See Basics of MPPT Charge Controller)

Example: A house has the following electrical appliance usage:

• One 18 Watt fluorescent lamp with electronic ballast used 4 hours per day.
• One 60 Watt fan used for 2 hours per day.
• One 75 Watt refrigerator that runs 24 hours per day with compressor run 12 hours and off 12 hours.

The system will be powered by 12 Vdc, 110 Wp PV module.

1. Determine power consumption demands

Total appliance use = (18 W x 4 hours) + (60 W x 2 hours) + (75 W x 24 x 0.5 hours)
	= 1,092 Wh/day
Total PV panels energy needed	= 1,092 x 1.3
	= 1,419.6 Wh/day.

2. Size the PV panel

2.1 Total Wp of PV panel capacity       needed	= 1,419.6 / 3.4
	= 413.9 Wp
2.2  Number of PV panels needed	= 413.9 / 110
	= 3.76 modules

                                                              
          Actual requirement = 4 modules
          So this system should be powered by at least 4 modules of 110 Wp PV module.

3. Inverter sizing
    Total Watt of all appliances = 18 + 60 + 75 = 153 W
    For safety, the inverter should be considered 25-30% bigger size.
    The inverter size should be about 190 W or greater.

4. Battery sizing
    Total appliances use = (18 W x 4 hours) + (60 W x 2 hours) + (75 W x 12 hours)
    Nominal battery voltage = 12 V
    Days of autonomy = 3 days

    Battery capacity = [(18 W x 4 hours) + (60 W x 2 hours) + (75 W x 12 hours)] x 3
                                                (0.85 x 0.6 x 12)
    Total Ampere-hours required 535.29 Ah
    So the battery should be rated 12 V 600 Ah for 3 day autonomy.

5. Solar charge controller sizing
    PV module specification
    Pm = 110 Wp
    Vm = 16.7 Vdc
    Im = 6.6 A
    Voc = 20.7 A
    Isc = 7.5 A
    Solar charge controller rating = (4 strings x 7.5 A) x 1.3 = 39 A
    So the solar charge controller should be rated 40 A at 12 V or greater.
