The world is increasingly going towards renewable sources of energy and one of the best possible alternatives to achieve this is by turning towards solar energy as a source of sustainable energy provision. Those who are thinking of solar energy should learn about the various forms of Solar setups. The major types are off-grid, and on-grid solar systems. Each person has their unique list of advantages, disadvantages, and uses for their 5 Marla home.
A solar panel system involves several essential and optional elements that can be added or eliminated depending on the specific solar system being factored and the individual needs. Solar panel systems are capable of generating electricity only when the sun is shining. The solar panel system will not be operating all other times. On-grid or off-grid systems can provide solutions to this problem using solar panel systems.
The on-grid solar system is connected to the national power grid. A solar inverter changes the direct current (DC) produced by the panels into an alternating current(AC) which can be used in 5 Marla Homes. In case you have a connection to a grid, you are able to feed the grid with more energy. The solar setup utilizes the available source of power. It maintains a steady supply of energy.
One of the benefits of on-grid solar systems is that they can help you save money on your energy bills. When you generate electricity yourself, then your energy costs will come down. Solar setups with net metering are also quite common. You can use any surplus solar power to forward it into the grid during the day. To this you are rewarded with points or money. This will further reduce your power bills and it can even eliminate your electricity bills.
The on-grid solar equipment ensures that a supply of power is always available. You will never run out of power with this sort of hybrid approach. It will not stop such off-grid systems that involves the use of batteries.
In most cases, the initial investment for on-grid solar systems is smaller than that for off-grid systems. It is cheaper to install them since they do not require the use of precise solar battery storage. This allows many homes and companies that wish to access solar energy to obtain cheaper on-grid systems.
Solar panels do not require a lot of maintenance and they are built to withstand different environments including weather changes, so they do not have a lot of working parts. They ensure the system is functional. The cost of maintenance is also reduced in the long run since no batteries to be repaired.
Using solar energy, you reduce your carbon and make the earth stay healthy. This assists the efforts made by Pakistan in combating climate and turning the future green.
Installing a solar system on the grid will increase the value of your residence. People are willing to purchase products with low consumption in terms of energy such as solar panels. They desire to pay less on energy and assault the earth less. This may be able to make your 5 Marla house more attractive to the people who may come to get it and also be able to increase its value when you choose to sell it.
You should understand the cost of an on-grid solar system. The following is the list of most critical cost factors:
In Pakistan, the prices of solar panels have become less expensive. This is due to the increased availability of providers in the market and the emergence of more advanced technology. The price ranges of solar panels are PKR 30,000 to PKR 50,000 per kW. Better quality panels could be expensive. They are more effective and arrived with superior warranties.
An inverter is another component of an on-grid solar setup. It receives the DC power supplied by solar panels and converts it into AC power. This is used at work and home. Transformers vary in size and type, the price likewise varies. In Pakistan, there exist various brands, and forms of hybrid or grid-tie inverters with prices starting as PKR 50,000 or PKR 100,000.
The installation cost has the labor cost, mounting equipment and electrical costs. Its installation cost is subject to change. The cost varies depending on the complexity of the system, the size of the installation as well as the location of land.
Net metering allows you to earn some money on something that you do not use solar energy. Fees may be charged, however. These may include application fees, meter installation fees, business running costs among others. Obtain information about the rules and fees for net metering with your local energy company.
Operating costs are not significantly elevated in on-grid solar systems. Regular cleaning of the solar cells at regular intervals, along with occasional checks, is sufficient. Other service providers provide warranties or repair programs. They will pay to fix and replace and this will reduce the upkeep cost.
It depends on size, its power consumption and energy cost. It will be worthwhile in 4-7 years. This will depend on the efficiency of the system and the savings of money used in power bills. The savings continue to increase after the loan is repaid. This will save your money in the long term.
This is an excellent method of people in Pakistan to use solar energy by using on-grid solar systems. These devices are a favorite among businesses and homeowners. They save money, electricity is steady, less is invested in investments and the planet is assisted. Using cost study, the on-grid solar systems turn out to be a good investment despite being heavy at the beginning of the investment. Generators, solar panels, and their establishment are costly. They save money and increase the house’s value in the long run.
On-grid solutions are excellent options of people wishing to utilize solar energy. They perform satisfactorily on the national power grid. Invest in sunny technology. It helps create a sustainable tomorrow. And also you will save money as well as the earth.
An off-grid solar system is an independent power generation system that is disconnected from the main electricity grid. In off-grid systems unlike on-grid systems which utilise the utility companies to provide backup power and excess power, the power generation will be utilised through renewable sources of sunlight.
An off-grid solar setup has a few important elements without which it will not work and you will lack power. The essentials are the following:
Solar panels absorb sunlight to give electricity which is also referred to as photovoltaic or PV panels. To have a sufficient amount of power toward an off-grid system, you will need several panels. The number of the panels and watts will be determined by your consumption of electricity and your battery capacity.
A charge controller is an accessory to your solar panels to ensure that your batteries are charged without being damaged due to a surge of electricity. The device will be used to obviate overcharging and protect your batteries against damage. Select a charge controller rated to work on your system.
We have a lithium iron phosphate battery, which is a rechargeable battery and is characterized by having an extended cycle capability, several high rates of discharging and thermal stability. Among the advantages of such a solar battery is that it is less prone to catching fire or exploding, unlike certain lithium ion batteries.
This is because it is necessary to convert the DC power your batteries have into AC power to run your appliances and electronics. An inverter serves this purpose. Use a pure sine wave inverter on sensitive loads, such as electronics, in an off-grid system.
You will require wiring to join the items, safety disconnect switch, the ground rods, and maybe lightning arrestor. Efficiently installed protection systems can assist in making your system run smoothly and avoid other dangerous issues such as electric shock, fire and electric power surges.
What this should mean is that you will be well on your way to a well designed off-grid solar power system knowing these key requirements. It is also important to remember the energy consumption and requirements, location, and budget of the places when building a personalized solar solution. By a bit of planning you will be able to attain energy independence and sustainability.
An off-grid solar system battery of 1 kW can supply and support approximately 3-4 hours of operation to run two fans and four lights. It is a feasible solar setup on small houses with 1 to 2 rooms, and it is estimated that it will be PKR 300,000 to 400,000.
The 3 kW system has a backup ranging between 4 to 5 hours and can support lights, fans and a TV. It is best suited for small to medium-sized houses, with an approximate price range of PKR 700,000 to 950,000.
An off-grid solar power system with 5 kW will run light, fans, a refrigerator, and other premises in 5-6 hours. This capacity is ideal in medium-sized houses and it costs typically between PKR 1,200,000 and 1,600,000.
A system with 10 kW is applied to large energy demands with the possibility to supply more than 8 hours of backup on various applications. It is most appropriate in large homes or shops and farm houses and the cost of installation is between PKR 2,500,000 and PKR 3,200,000.
We may have a look at the major differences:
| Aspect | Off-Grid Solar System | On-Grid Solar System |
| Grid Connection | Not connected to the utility grid. | Connected to the utility grid. |
| Access to Electricity | Limited to solar generation and battery storage. Needs big batteries and perhaps a generator to keep power on. | Grid access to electricity at all times even during periods when the solar system is not generating. |
| Power During Grid Outages | Unaffected by grid outages; operates independently. | Does not work during grid outages for safety reasons (utility worker protection). |
| Excess Electricity Handling | Excess electricity is stored in batteries for later use. Needs a large and costly battery bank. | Excess power is fed into the grid and compensated via net metering (if available). |
| Electricity Bills | No electricity bills, since it’s entirely independent of the grid. | May receive bills for grid usage, service charges, or if more power is consumed than produced. |
| System Cost | Higher cost due to battery bank and generator setup. | Lower upfront cost, especially without battery storage. |
| Energy Independence | Complete energy independence. | Partial dependence on the grid. |
| Suitability | Ideal for remote or rural locations with no grid access. | Best for urban or suburban areas with reliable grid availability. |
| Reliability | Highly reliable if batteries are adequately sized; dependent on sunlight and battery level. | Highly reliable when paired with net metering; limited during outages unless hybrid. |
As is always the case, selecting an off-grid or an on-grid solar system is a matter of personal preferences and requirements. Look at elements in terms of whether you can afford a particular system, how you use power and the availability of the electricity grid.
A grid-connected system might be ideal if you are located in a grid-liable region to take advantage of net metering. An off-grid system, on the other hand, may be more suitable, as it has energy storage capability, either in a remote area or in case you wish to be independent of the larger energy grid.
Eastern Housing Lahore is a developed modern urban society with reliable and stable accessibility to the national electric grid. This prefers to use an on-grid solar system, which is more feasible and affordable to the majority of homeowners in the region. By opting to use an on-grid system, residents will have the opportunity of making the best of net metering, where they can feed solar energy to the grid which can be credited or deductions can be provided to them as far as electricity charges are concerned.
In addition, the on-grid systems do not depend on the costly services of battery storage hence their initial investment cost is considerably lower than that of two off-grid systems. This solar setup will also be capable of supplying steady and consistent electricity since the grid will be used to step in whenever there is low solar generation like at night or when it is cloudy.
Which one best suits you will be contingent on your special needs and environment in 5 Marla home. Neither of those two systems (off-grid or on-grid solar system) is actually more advantageous than the other, they both have their disadvantages and advantages. The two solar setups will facilitate some form of eco-friendly and sustainable energy which will improve the use of non-renewable resources. By choosing either the necessities of on-grid or the independence of off-grid solar systems, using solar energy adds a reasonable sense of a green and sustainable world. So, select wisely according to your needs.
