Hello and welcome to ReviewsPK! My name is Ameer. We are seeing for a long time that there is a shortage of power in Pakistan, because of which we also saw load shedding and the cost of electricity in Pakistan is very high, now there is a way that the pressure of demand of the electricity you can lighten it up from the system and along with it you can save money as well as make money. You definitely have heard the term renewable energy, this is a type of energy that we take from wind or hydro that is from water or solar, that is from the Sun So, in today's video we will talk about how you can use Solar energy, with the help of an On-Grade Solar Power System, by placing it at your home or in your office, not only you can save money but you can also make money.
I hope that our today's video will be beneficial for you, and if you have any benefit from it then I request you to share it with your friends as well, so that they can also take advantage of it. So that is all for the intro. Lets move towards the video now. Keep watching. Special thanks to MASCO SOLAR who helped us in the production of this video. Visit their website for further details.

And now we are on Instagram as well so follow us @reviews_pk What is Solar Power system after all? and what is its purpose? In a solar power system, or in a photovoltaic system, there are some solar panels which are placed on the roof, or in any other open area where the sunlight shines bright.
The size of a Solar panel is usually 1m x 2m and its peak output ranges from 330V to 400V. When the sunlight strikes on these panels, they produce electricity from this sunlight. And these panels are connected to an inverter. The electricity that is produced from the solar panels enters this inverter in the form of a D/C current and converts into an A/C current on which your bulbs, fans, TV, etc runs. Every solar power system has a total Kilo Watt capacity. And this system, at its peak, meaning at its maximum capacity, works at that time of the day when the sunlight is at its maximum. We call this KWP, meaning Kilo Watt Peak Output. And just as the sun sets, the output of the system also reduces gradually and becomes zero at night. As much electricity an On-Grid system produces it is utilized at your home or in your office. And any else need other than that, is overcomed by the Grid Electricity, meaning WAPDA, KE, etc. And if your system is producing more electricity than you need, then it is supplied in the Grid by using Net-metering. But we will talk about that later in the video.
Lets talk about the cost of a Solar Power System now and how much money can you save or make from it? Primarily, the cost of a Solar Panel depends upon these four things: The Quality of the Solar Panels, The better the quality, the longer the life and the greater the output of electricity will be. The Quality of the Inverter. Obviously, the greater the quality, the more experience would it be. The material of the stand or structure that holds the Solar Panels. Galvanized iron is cheap but it rusticates with time and its durability is not like that of Aluminium If we use the Aluminium stands, then they are expensive but they don't rusticate and goes on for long. And lastly, which quality of wires are being used. If we take a collective look at it, then an On-Grid Solar Power System, that excludes the batteries, its cost vary from Rs 90/- to Rs 120/- per Watt.
This is just a superficial account. But for our today's video, we will take the figure of Rs 100/- per Watt. And according to that, a system of 5,000 Watts would cost you around Rs 5,00,000/- and keeping in mind, this system will produce 5 Kilo Watts only when maximum sunlight is striking upon it. But the sunlight shines differently in every area. Less at some places, while more the others. So how much sunlight gets in your area, how to find that out? Guys, this is 2019 and the technology is very vast now. There are such websites available where, when you enter your location, they can let you know that considering day-night and summer-winter cycles, how much sunlight will get in your area. And one of such tool is Global Solar Atlas. Which is formed with the participation of World Bank. The address of the website is globalsolaratlas.info Click on the location search bar here and enter your city. Keeping in mind that the amount of production of electricity will vary according to each city. There will be all these details on the right side.
If you will scroll down here, there will be a section of 'CHOOSE PV SYSTEM TO CALCULATE ENERGY YIELD' where you will choose your category. Ours is small residential. Then, a new window will open when you will click on
'change PV system' You can enter the details of your system here. 'Azimuth' is the direction of your panel. We will let it be on 'Optimum' And 'Tilt' is the angle of your panel. We will let it be on 'Optimum' as well. The person who would be installing your Solar Panel, would know these things if he would be smart. And below this is 'System Size'. We will change 1 Kilo Watt into 5 Kilo Watt here. and then we will click on 'Apply'. So here, we got 8.010 Mega Watt hours per year. Meaning, in a whole year, considering summers, winters and day-night cycles, your system, will produce 8.01 Mega Watt/hour meaning 8,010 Kilo Watt hour meaning 8,010 electricity units. But obviously, this is just an estimation, and in actual the electricity might be less or more than this.
I asked MASCO SOLAR about this, they said the difference is very minor. Meaning, its superficial account is quite accurate and they use it regularly. So guys now we know that how much electricity our Solar Power System will produce in our area. Now we will calculate that how much money we will save. One unit of electricity here, meaning 1 Kilo Watt hour ranges from Rs 12/- to Rs 22/- And it depends upon where you live, and whether your electricity connection is of home, commercial or of business.
And how much of electricity do you use? Suppose if our single unit is of Rs 15/- then according to 8,010 kW it results in Rs 1,20,150/- If we consider a 90% downtime as well, then that results in Rs 1,08,135/- If our system cost us Rs 5,00,000/- then the total payback time is 4.6 Years. Meaning, in 4.6 Years, we will get our money's worth. As much expensive the unit, as much of the savings, and as early you'll earn the worth of your money. So if your electricity is more expensive than this, you will get the payback earlier.
If we talk about the life of Solar Power Systems, Then usually, the rated life of Solar Power systems is said to be almost 25 Years. And the inverter that is present along with it, its life is also said to be around 15-20 years. And if you will buy it of a good quality, they usually come with a 5-Year warranty as well. So guys, we will talk about Net Metering now. The concept of Net Metering has been used in plenty of other countries before. Net Metering means that all your electricity production which is more than your needs, you can sell it into the system. If you do not have Net Metering, then all of your extra production will be wasted. To activate the Net Metering, you usually have to submit an application form for that. After that, your site inspection is done. And when all the approvals are done, then a bi-directional meter is fitted at your home. It is different than a regular meter because a regular meter is only one way but this is bi-directional. Meaning, it sends as well as receives the electricity. And its price is also said to range between Rs 40,000/- to Rs 70,000/- So after activating Net Metering, you could provide electricity to the Grid, and at the end of the month all the electricity that you would've provided, it will either Net-Off from your bill and all the amount above it, you will receive via payment.
Let me add one thing here, check this in your area too that if anyone has Net Metering, then ask them whether or not they are receiving the payments n time? I will not take any responsibility regarding this matter. Don't get stuck in any unfortunate event or any other issue. Therefore, research about it yourself. Along with that, on every location a limited number of Net Metering connections will be given. So if that limit has reached in your area, then you won't be able to get it. So it will also be good if you researched it first that whether more spots for Net Metering are available in your area or not.
Lets talk about some downsides of On-Grid Solar Power System. So the first downside is that there is no battery in On Grid systems. Because of which, when there is no sunlight, then you would have to use the electricity on the Grid Along with it, if you have no electricity and even if the sunlight is there, this system still won't work. Because it requires a reference voltage to work Another downside is that although the life of Solar Panels is quite long, but other things of the system, like inverters, the stands under the Solar Panels, and wires, can get destroyed with time. So they might need repair and maintenance time to time. And no system works on a 100% efficiency and there will be some downtime.
We took a suppository number of 10% in our calculations, but if the downtime is longer than that then it might take longer to payback. So this was some of our research on Solar Energy. Right now, Solar Energy is catching speed in Pakistan. And the primary reason for that is its payback is very quick. 4 to 4.5 years is considered great in business sense. And if your electricity is more expansive than this, then your payback might be in 3 to 3.5 years as well. And as the electricity will get more and more expansive with time, then this deal will get even more sweeter. And it takes only few days to set it up, not much long. So my advice to you would be that if it is workable in your area, then you must consider it. If you want to share your Solar Power experience with us, then let us know in the comment section below.
