Solar farms offer scalability, allowing them to be customized to meet specific energy demands. Solar farms can be created and put into operation modularly, offering flexibility and adaptation, whether it’s a small-scale installation for a neighborhood or a significant utility-scale undertaking.

Technology evolution

The development of photovoltaic technology is still ongoing. The potential for creating more sophisticated solar cells and cost-effective production techniques is enormous. It is anticipated that photovoltaic technology will advance over time if past trends are any indication. Additionally, the cost per watt of power will drop. The solar sector will expand and become more accessible shortly.

Reduce the use of fossil fuels

The majority of the world’s energy still comes from fossil fuels. A small portion of the world’s overall energy supply comes from renewable sources. The worst pollutants are coal and natural gas power stations, which release millions of tons of carbon dioxide annually. We can lessen the adverse effects of fossil fuels by going toward solar farms.

Promotes energy democratization

Promoting energy democratization gives people and communities more authority over how much energy they produce and use. With solar farms, people can generate electricity, reducing dependence on centralized power grids and traditional energy providers. This decentralization of energy production allows for greater energy independence and choice.

Solar farms allow people and communities to actively participate in the energy transition by transforming from passive consumers to active providers of clean energy. This encourages the development of a more democratic energy system where a larger population, regardless of location or socioeconomic level, may benefit from renewable energy.

Increase the local economy and employment

This argument might not be very persuasive, considering that other power plants have the same issue. The local economy is boosted, and solar farms create jobs. However, the early stages of the project, before commissioning, receive the most boost and employment creation.

Additionally, the bulk of occupations are contract-based. Additionally, since there is more employment, there are more expenses, which drives up the cost of power.

Zero emissions

Fossil fuel power facilities emit many pollutants and chemicals, including greenhouse gases, into the environment. The increase in carbon dioxide levels causes a serious threat to the ecosystem worldwide. Contrarily, emissions from solar farms are completely negligible.

They are pretty eco-friendly. There are no greenhouse gas emissions in the direct form. Unlike nuclear power plants, they do not discharge any radioactive nuclear waste.

It is crucial to remember that solar panels and other components do, in fact, already have a carbon footprint. This indicates that carbon dioxide and other gases are emitted while manufacturing solar modules and other solar farm components. However, this greenhouse gas emission pales in comparison to the total beneficial effects of solar farms.

Cons of Solar Farms

By examining the benefits of solar farms, it is evident that they have a promising future. But they still have a lot of problems that need to be fixed. The drawbacks of solar farms are listed below.

Land and habitat impacts

Solar farms require significant land for installation, especially for large-scale projects. This can lead to habitat disruption, fragmentation, and the displacement of wildlife. The clearing of land for solar farms can have adverse effects on local ecosystems and biodiversity. Careful site selection and impact assessments are necessary to minimize these impacts.


The initial capital investment required to construct and install solar farms can be substantial. Costs include land acquisition, equipment, and installation expenses. Although the price of solar panels has declined, some investors or communities may still find the initial expenses a barrier. The fact that solar farms have much lower long-term operational costs than conventional electricity facilities must always be kept in mind.

High-cost energy storage

The weak storage cells in today’s cell phones are one of its many issues. Because of this, we are forced to charge our phones or use battery backups constantly. Solar technology has a similar issue.

Electricity is generated via solar farms during the day. But the solar panel system won’t function at night or in the evening. As a result, the grid won’t be able to power our homes with solar energy at night. Batteries are useful in this scenario because we can store the energy during the day and use it at night.

The problem with batteries, though, is their high price. They are heavy and quite pricey. When we desire a device to have a long battery life, it makes our cell phones and computers more expensive and bulkier.

Storing all the extra energy PV panels produce is not a good idea. The solar farm’s economics might not be successful. Moreover, the project can become impossible.

Manufacturing and disposal of solar panels

The production of solar panels involves the use of various materials, including rare metals and chemicals. The extraction and processing of these materials can have environmental consequences, including habitat destruction and pollution.

Additionally, at the end of their life cycle, solar panels can contribute to electronic waste if not properly recycled or disposed of. Appropriate recycling and end-of-life management procedures are crucial to reduce the negative environmental effects of the production and disposal of solar panels.

Take up a lot of room

There is no denying that renewable energy has a terrible reputation for requiring a lot of land. According to an NREL analysis, the one-axis photovoltaic system requires 8.7 acres of land per MWAC.

On the other hand, a straightforward analysis from strata.org indicates that each MWAC of coal power in the US requires 0.699 acres of land. The stark contrast between the two values is evident. Compared to coal power plants, solar farms require a lot more space.

Solar farms do have the advantage of having easily recoverable land, though. On the other hand, reclaiming the land utilized by coal or nuclear power facilities is expensive.

Low capacity factor and high upfront costs
