Factors Affecting 7kW Solar System Price in Pakistan
Besides all the things, there are some factors which greatly affect the 7kW solar system price in Pakistan and the budget can be adjusted by keeping these factors in mind.
- Good quality and branded solar panels are always expensive as compared to basic traditional solar panels. But expensive ones give a relaxation of mind, provide long life-span and best performance over years.
- Solar panels’ price mainly vary depending on the type of solar panels. N-Type solar panels are expensive than P-Type panels, Bifacial(Double Glass) solar panels are expensive than Monofacial(Single Glass) solar panels. The all new Longi Hi-Mo X10 is expensive of all due to its out-standing performance and technology. So choosing among types of solar panels can decrease and increase the system cost.
- Solar inverter is the second most important component of a solar system. Without it, obtaining maximum efficiency from the solar system is not possible. Solar inverters of different types and technology are present in the market and have different prices. So choose the one which adjusts in your budget.
- Installation cost matters for consumers when installing solar systems. It depends on the capacity of system i.e. high capacity solar system’s installation is more than low capacity solar system. Labor cost, type of solar system, type of roof etc. all may increase the cost in case of big solar systems.
- If you are installing hybrid or off-grid solar system, then the batteries are also included in the package. Batteries are crucial in hybrid and off-grid solar systems. If using off-grid system, then more batteries will be required or if using hybrid system, then number batteries will be decreased. The capacity of batteries to use also depend on the backup time. If you want more backup time, then you need more batteries and this is different for both hybrid and off-grid solar systems. We have explained that below in a separate section.
Units Production of 7kW Solar System in Pakistan
A 7kW can reduce bills 100% because it generates enough electricity for easily for a normal house. In Pakistan, peak of sunlight is 5-6 hours and size of solar system is 7kW. So to find out daily production of units of electricity by 7kW solar system, we have to apply the formula: Total Production= Size of System x Sunlight Hours.
- Daily Production of Electricity Units = Size of System x Sunlight hours = 7kW x 5.5 hours = 38.5 Units or kWh
- Monthly Production= 38.5 x 30 = 1,155 Units or round about 1000 Units or kWh
- Yearly Production= 38.5 x 365 = 14,052.5 Units or round about 14,000 Units or kWh
The production of units may decrease depending upon the weather. During cloudy conditions, the production may reduce to 800-900 Units per month.
Appliances Supported By 7kW Solar System
A solar as big as 7kW can power all the appliances of a house without turning off other appliances when using large load appliances. Below is a table of detailed overview of appliances that can run on 7kW solar system.
| Appliances | Power Consumption | Quantity | Total Load |
|---|---|---|---|
| LED Bulb | 10W | 10 | 100W |
| Ceiling Fan | 80W | 4 | 320W |
| Inverter AC(1.5 Ton) | 1800W | 2 | 3,600W |
| Refrigerator | 150W | 1 | 150W |
| Water Pump | 750W | 1 | 750W |
| LED TV(42 Inch) | 100W | 1 | 100W |
| Laptop | 60W | 2 | 120W |
| Mobile Charger | 30W | 4 | 120W |
| Iron | 1,000W | 1 | 1,000W |
| Washing Machine | 500W | 1 | 500W |
| 6,760 Watts |
The Load after using all the necessary appliances is 6,760 watts and 240 watts are still left which would be used when more watts are required by any appliance. This will help the appliances to stay safe in case of any power outages.
Usage of Batteries in 7kW Solar System
Batteries are used in 7kW solar system only in hybrid and off-grid solar systems. Lets take a look at both of them. If you are installing hybrid system, then the use of batteries depend on the backup time. As we know, it is also connected to grid so 3-5 hours of backup is enough for hybrid system. If you want 4 hours backup time, then 12 batteries of 12V 200Ah will be connected such that set of 4 batteries will be connected in series and according to 4, 3 sets of batteries will be connected in parallel. You can increase or decrease backup requirement according to your needs.
Now we come to off-grid solar system. If you want a backup time of 8 hours in case of off-grid solar system, as the system is off-grid so usually more backup time is used, then 24 batteries of 12V 200Ah will be connected in such a way that 6 sets of batteries will e connected in parallel and each set will have 4 batteries connected in series. This might look terrible to understand but the professional installers would be taking care of that during installation.
Savings After Installing 7kW Solar System
After installing 7kW solar system, consumers may get several savings. Electricity bills get reduced 100% and you don’t have to pay for electricity bills. Instead you can earn credits by net metering if you are using grid tied or on-grid solar system. In net metering, the extra energy generated by solar panels is sent back to grid utility and you get payed for it. There is also a benefit of 7kw solar system it provides 24 hours electricity without any interruption.
Components of 7kW Solar System
A 7kw solar system consists of the following components:
- First of all is the solar panels and without them a solar system is not a solar system. These are TIER 1 solar modules from the top brands like Longi, Canadian, JA, Jinko, Trina and other famous brands.
- Second thing is the solar inverter which provides maximum efficiency of solar system and optimizes the system for maximum output.
- A monitoring system for detecting the performance of solar system from time to time.
- Solar panel mounts on which solar panels are to be installed for protection.
- You can also consider batteries as components if installing hybrid or off-grid solar system.
- DC and AC cables for connecting all the components together in a system.
- Disconnect switches also play an important role in the protection of solar system.
Area Needed for 7kW Solar System Installation
Usually, for 1kW solar panels’ installation, 100-120 sq. ft. area is required. Let’s take an average of 110 sq. ft. of area for 1kW solar panels’ installation. According to this, 110 x 7 = 770 sq. ft. of area is required for 7kW solar system installation. If the roof is flat, then 770 sq. ft. of area is good. But if the roof is tilted mounting, then 800-850 sq. ft. area will be required.
Conclusion
A 7 kW solar system is an ideal choice for medium to large households and small businesses in Pakistan. It can efficiently power multiple appliances, reduce electricity bills, and provide backup during load shedding. With an average daily production of around 38.5 units and a monthly generation of approximately 1,155 units, a 7 kW solar system offers a reliable and cost-effective energy solution.
While the initial investment may seem high, the long-term savings on electricity bills and the potential to sell excess power to the grid through net metering make it a smart and sustainable choice. Investing in a 7 kW solar system can lead to energy independence and significant financial benefits over time.
