How to effectively install a solar system for your home in Pakistan?
In this era of advancement and technology our nation is still relying on the oldest way to generate electricity, whole world has now moved to the advanced technologies of energy harvesting and the most reliable one is via solar energy, this procedure costs less and it is more effective as compared to the old conventions of harvesting energy, the main motive of this article is to, To attract people of Pakistan toward this innovation, To Give people awareness about this natural way to generate electricity, How effective this solar phenomena will be in our homeland.
As we all know that the main sources of electricity generation in our country are only three which are Thermal Power, Hydro Power and Nuclear power, and all these phenomenon are very costly and due to high demand of electricity in our country we are unable to fulfil the demand of user as result breakdown of electricity often occur in summers, due to high demand of electricity government implements different time plans to get rid of this shortage problem and still we didn’t find a suitable solution for this problem, but now solution is available we can use sun light to produce electricity and use it in our homes easily whole world has moved to this technology because cost of this method is quite low and there will no distortion of electricity in this method. After seeing the climate of Pakistan this solar energy harvesting method can be very effective for the whole community and no one will depend on the supplier companies to provide services.
As per rich climate of Pakistan we have effective sun light which can be utilized to produce electricity from it and work has already started by the private companies which are providing equipment to generate electricity from sunlight, government of Pakistan also want to get rid of this energy crisis and that’s why solar energy systems parks are also build in difference t hot cities of Pakistan where effective sunlight can be used to complete the needs of energy, The main government made pant of solar energy is situated in Bahawalpur and that consists of 500 acres and once it will get completed then the generation capacity of this park will be 1000MW.
Every year our demand and supply fluctuated in between the figure of 5000MW – 7000MW and as result we all face unavailability of electricity for several hours, Chinese companies are also cooperating with Pakistan to overcome this crisis, A Turkish company (Zorlu Enerji Holding) has also offered there services in the beginning of 2017 that will also help to build more solar energy harvesting power plan. This method can only be effective in that regions where sunlight remains effective for most of year, and we can also use this project for the larger production because we have some hot areas in Pakistan,
MAIN WORKING OF SOLAR POWER PLANT:
Solar phenomena of energy harvesting is quite easy to install every place where effective amount of sunlight reaches and that can be used to generate electricity.
Following thing needed in making of solar power bank which can be used to run home appliances:
- Good quality solar panel
- Internal circuit( maybe vary on demand, Arduino based or controller based)
It is very simple to install this system in home it only need smaller space on the roof where we can fit solar panel, solar panel is designed in such a way that it convert solar energy into the usable electric energy and then we can store that energy into battery then via help of invertor we can use that harvested amount of electricity to our needs in home, this is a low cost phenomena to produce electricity and it is far less cost consuming as compared to other ways to produce electricity.
Types of Solar Panels :
Solar panel of different sizes are available in market for the residential energy harvesting and many local and branded companies are providing solar panels in the market. The common size used in residential plants are 65 by 39 inches while in commercial 77 by 39 inches is used. And TESLA is the largest manufacturer of solar panel in Pakistan and it provide wide variety with
Different panels with difference generation capacities are also available in market as per user requirement. It depend on the electricity consumption of that house where this system is to be fitted and there are different types of solar panel are available which are distinguished on basis of generations.
In first generation solar panels there are following types:
- Monocrystalline Solar Panels (Mono-SI)
- Polycrystalline Solar Panels (p-Si)
- Thin-Film: Amorphous Silicon Solar Panels (A-SI)
- Concentrated PV Cell (CVP)
The best one to use from the first generation solar panel is Concentrated PV cell because its efficiency is quite higher up to 41% as compared to the rest of types and it can be more enhanced by the tracking of sun.
Prices also varies as the precision of efficiency increase and the if you are going for the low cost then mono crystalline will be suitable and if you want a mild one then it will be thin film “ AMORPHOUS SILICON SOLAR PANEL”. And if you want high precision without any cost hurdle then go for CVP.
Prices of Solar Panels in Pakistan are as Follows:
Mono-crystalline solar panel cost for normal residential use in Pakistan is round about Rs.12000, and the price of Poly-crystalline for normal house is Rs.15500 and price for thin film solar panel is round about Rs.10500 for 121 watt production and now the best one for the efficient use that is CVP that cost Rs.20000 per 250 watt cell.
Following brands are here available in Pakistan that are providing their solar system in the market and most of them are international brands and they prices are also reliable for the home use,
- Canadian Solar ( Canadian company)
- Lorentz ( German brand)
- Yingli ( Chinese brand)
- LDK ( Chinese brand )
Other local brands are also available but their performance is not guaranteed that’s why they are not included in the list,
Now coming toward the another major part of solar plant that is invertor and it is very essential because the energy produced by the solar panel is in DC and invertor will be used to convert it into the AC so that out home accessories can work easily and we can find many type of solar invertor in market, it depend on the user requirement how much he can spend to make his solar plant more effective and efficient and types of invertors used with solar panels are:
- String inverter
- Central inverter
- DC/DC converter Power optimizer
The best inverters to use for higher efficient result are:

Types of Batteries use for solar system:
Specific batteries are used with the solar panel to operate home appliances and It depend on the consumption of electricity and production that which one is suitable for the system. Those are enlisted as following.
- Lead Acid Batteries
- AGM Batteries
- Lithium ion Batteries
It depend on the user which kind he want to use as according to the power plan. AGM batteries are best for use because these are built on the advance technologies and their efficiency is also higher as compared to others and its cost is also higher as compared to the rest of others.
Solar System Fitting Cost in Pakistan:
Cost mainly depend on the consumption of electricity in a house and mainly for a normal house solar system of 2000 watts cost for 3 to 4 lacs and it is way better than the paying of electricity bills on monthly basis only you have to bear expense in start and then you will enjoy free electricity for the rest of life and there are different companies providing fitting of system and whole life maintenance for free and their work is totally outstanding, prices varies per 100 watt and every house has his own consumption so this price may not fit for every user.
- Pak solar services
- Nizam energy company
- Premier energy company
- SE solar Pakistan
As we are still under developed country this idea will take a lot of time to get famous In our region only few people have knowledge about this technology but world has gone above this, now sun tracking solar systems are also available which are more efficient as compare to this fixed solar systems. I will write whole article on that type of solar systems sooner or later and it will take time to get adjusted in our society and as a nations we should accept the new technologies and this innovation can reduce load shedding to the lower level and we can provide nonstop facilitation to every area.
