If you want to install a 20 kW system, the first question that may pop into your mind is: How much power does a 20 kW solar system produce per day in Pakistan? By power, we mean the amount of electricity used.

This is precisely what we will talk about in today’s post.

More specifically, we will discuss the following:

How to determine the output power of a 20kW solar system?
How much electricity (units) does a 20kW solar system generate in Pakistan?
Factors Affecting the Production Capacity of a 20kW Solar System.
Power is generated by 20kW solar systems in various cities of Pakistan, including Islamabad, Karachi, Peshawar, Quetta, Lahore, and others.
How can the energy production of a 20 kW solar system be optimized?

Before calculating the power output, several factors that affect the power generation capacity of solar plates must be discussed.

Factors Affecting Solar Power Production of 20kW Solar Systems

The electricity generated by a 20 kW solar system depends on various factors. This can lead to different power outputs in different locations, even if they have similar characteristics. For example, the same 20 kW system can produce different power under various conditions.

Why? Let’s see!

Solar radiation levels in your area

First, the amount of sunlight a solar system receives is the main factor determining its power generation. Pakistan has peak sunlight hours of 4 to 7 hours per day, making it a near-perfect location for solar power generation. However, the availability of sunlight can vary depending on the season and location within the country.

For example, Islamabad receives about 5.5 peak hours of sunshine, while Skardu gets about 3.4. This means that a 20 kW system installed in Islamabad will generate more electricity than its counterpart in Skardu.

Efficiency of solar panels and inverters

The efficiency of solar panels and inverters is crucial in determining how much electricity is produced. In Pakistan, the average efficiency of solar panels is around 18%, with newer panels offering an efficiency of over 20%. The more efficient your solar panels are, the more sunlight they convert into DC electricity.

When we talk about direct current, we need to convert it into alternating current using inverters. To fully convert the generated electricity into helpful energy, we recommend high-quality inverters with an efficiency of over 97%.

Solar panel orientation and tilt angle

When multiple solar panels are grouped together, we call it a solar array. The orientation and tilt angle of your solar array will significantly affect the power output of your 20kW solar system. For best results in Pakistan, solar panels should ideally face south at 180 degrees. The tilt angle should match the latitude of the installation site, which ranges from 23 to 37 degrees.

In Islamabad, the elevation angle will be around 25-40 degrees – the lower range for summer and the upper range for winter. If you want optimum performance throughout the year, it will be around 30 degrees. The correct orientation of the panel ensures maximum exposure to sunlight throughout the day.

Shading and Obstructions

Next, we have shading and obstructions. Shading from nearby structures, trees, or other obstructions can reduce the output of solar panels. Installing panels in locations with minimal shading is essential to maximize energy production. In situations where shading is unavoidable, measures such as using microinverters (if available on the market) can minimize their impact on system performance.

Dust and debris

Finally, the accumulation of dust, debris, or bird droppings on solar panels can reduce their absorption of sunlight, resulting in poor power generation. Regular cleaning and maintenance of solar panels are essential to ensure optimal performance and maximize power generation.

Understanding 20kw Solar Power System Power Generation in Pakistan

While calculating the power output, we will consider some of the factors mentioned above. Based on this, a typical 20 kW solar system in Pakistan can generate 68 to 100 kWh (units) of electricity daily, approximately 2040 to 3000 monthly units.

A 20 kW solar system is capable of powering large homes or businesses that consume approximately 2,000–2,500 kWh of electricity monthly. It can quickly run various appliances, including refrigerators, air conditioners, and other electrical equipment.

What is the daily production of a 20 kW solar system in terms of solar energy units?

To calculate the electricity generated by a solar system, use the following formula:

“Daily production of a solar panel = Solar panel capacity x Peak sun hours x Efficiency factor”

For a 20 kW system:

Daily Production = 20,000 watts x 5 hours x 0.8 = 80 kWh (units)

Please note that actual power generated can vary based on location, weather conditions, and system efficiency.

For example, in areas with 6 hours of sunshine, the energy generated daily will be 96 kWh (units). Similarly, the number of units generated may be slightly less in winter.

How many solar energy units does a 20 kW solar system produce monthly?

Calculating your monthly production volume is easy. Just multiply your daily production volume by 30, and you’ll get the result.

Monthly production of 20kW solar system = Daily production x 30 = 80 x 30 = 2400 units (kWh)

As discussed, the electricity generated monthly may vary depending on the abovementioned factors.

20kw Solar System power generation in different cities of Pakistan

The power generation potential of a 20 kW solar system may vary slightly across cities in Pakistan due to differences in solar radiation levels. Let’s look at the power generation estimates for major cities in Pakistan.

How much electricity does a 20kw solar system generate Power in Islamabad?

In Islamabad/Rawalpindi, a 20 kW solar system can typically generate between 78-88 kWh of electricity per day, totaling around 2,500 units monthly. With favorable solar conditions and net metering, Islamabad is an ideal location for solar power implementation. Additionally, since there is minimal load shedding, installing a grid-tied system makes practical sense.

How much electricity does a 20kw solar system generate Power in Karachi?

In Karachi, a 20 kW solar system can generate an average of 80-88 kWh of electricity per day, amounting to approximately 2,520-2,880 units per month. Karachi’s solar irradiation levels align with the national average, with around 5.2 peak hours of sunshine per day, making it a promising location for solar power. We recommend a hybrid solar system if your area experiences frequent load shedding.

What is the power output of a 20kw solar system in Lahore?

Similar to Islamabad, Lahore can also generate an average of 80-90 kWh of electricity per day with a 20 kW solar system. Depending on your requirements, you may consider installing a hybrid solar system.

How much electricity does a 20 kW solar system generate Power in Peshawar?

A 20 kW solar system in Peshawar can generate an average of 82-90 kWh of electricity daily. We will recommend a hybrid solar system for Peshawar as load shedding in some parts may not work well with an on-grid solar system.

How much electricity does a 20kw solar system generate Power in Quetta?

In Quetta, a 20 kW solar system can produce an average of 72-88 kWh of electricity daily. Quetta gets an average of 5.1 kWh/m²/day of solar irradiation. In summer, due to higher solar irradiation, it can achieve a higher power generation potential.

What can be used with a 20kW solar system?

A 20 kW solar system can power many appliances in a large home or medium-sized business. With more power than a 15kW solar system, a 20 kW setup can support more appliances simultaneously.

Here are some examples of devices that can be used with a 20 kW solar system:

Up to 20 fans
Up to 35 lamps
Either 4 units of 1.5-ton air conditioners or 5 units of 1-ton air conditioners (not permanent)
3 microwaves
One iron
Three refrigerators
5 LED TVs
Two washing machines
Four things.

And more.

The power of these appliances depends on the efficiency of the solar panel, the availability of sunlight in the area, and the usage pattern of the appliances. Note that you can run even more appliances – make sure that the instantaneous load does not exceed the instantaneous generation capacity of your solar system.

How to Maximize the Power Output of Your 20 kW Solar System

To maximize the power output of your 20 kW solar system, consider the following measures:

Choose high-quality solar panels with higher efficiency ratings. Investing in quality solar panels and avoiding low-quality components such as inverters and switches will ensure optimal performance.
Ensure the correct panel orientation and angle. Professional installers can effectively optimize sunlight exposure throughout the day to maximize your system’s performance.
Clean and maintain panels regularly, removing dust and debris to ensure they operate at their best.
Monitor the system’s performance to identify any problems or inefficiencies. If you experience any problems, contact your solar panel installer immediately, as faulty equipment can affect the entire system’s performance.
Choose an appropriate installation location to minimize shading. If your solar panel array is subject to shading, then regardless of the efficiency of the solar panels, your system will operate below the recommended level.

How much electricity does a 20kW solar system generate?
