Solar Energy: Advantages and Disadvantages

What is Solar Energy?

The most potent resource on Earth is solar energy. It can be gathered and used in various ways and is an important element of our clean energy future as a source of renewable power. Solar energy is the Sun’s radiant light and heat used by various technologies, such as solar heating, Photovoltaics, solar thermal energy, solar architecture, salt plants and artificial photosynthesis. The energy supply is always evolving.

Decrease the carbon footprint

Solar power is free of pollution and does not emit greenhouse gases after installation. Solar is a clean and renewable energy source which can help lower emissions of carbon dioxide and reduce our environmental impact.

Reduced foreign oil and fossil fuel dependency

Unlike traditional fossil fuels such as coal and oil, solar energy does not directly lead to air and water emission of pollutants (like carbon dioxide). Solar is a more environmentally friendly solution even in comparison to nuclear energy.

Renewable Source of Energy

The clean energy available each day of the year produces a certain amount of power even in cloudy days. The most important thing is that solar energy really is a source of renewable energy among all the advantages of solar panels. It is available every day and can be used in all areas of the world. Unlike some other sources of energy, we cannot run out of solar power.

Solar energy will be accessible as long as we have the sun, so we have at least 5 milliards of years of sunlight when scientists say the sun will die.

Investment return unlike payment of bills.

As the electricity that your solar system generates meets some of your energy needs, your energy bills will drop. The size of the solar system and your use of power or warmth will depend on how much you save on your bill.

This switch can have great benefits, for example, if you are a company that uses commercial solar panels because the big system size can cover large parts of your energy charges.

Virtually no maintenance for solar panels as it last over 30 years

In general, solar power systems do not require much maintenance. You just have to keep them relatively clean, so it is a job to clean them several times a year. 20-25 years guarantee is offered by the most reliable manufacturers of solar panels.

There is also no wear and tear because of no moving parts. The inverter is the only part which has to be changed after 5-10 years, since solar energy is always transformed into power and heat (solar PV vs. solar thermal). In addition to the inverter, the cables also need to be serviced to guarantee maximum efficiency of your solar power system.

Therefore, you can expect very little maintenance and repair expenditure after the initial solar system costs are covered.

Sets up jobs through the employ of manufacturers of solar panels, solar installers…

Excess energy can be returned to the power company if the grid intersects

In addition, you can not only save on the electricity bill but also receive surplus energy payments which you export back to the grid using the Smart export guarantee (SEG). If more electricity is generated than used (considering that your solar panel system is connected to the grid).

Grid free environment

The ability to live without grid, if sufficient power for the house / building is generated. No trenching is required because the solar can be near or at the installation site.

Energy independence

In contrast to coal and natural gas the sun is an infinite energy source, and almost everywhere solar panels can be installed. Solar panels can reduce your dependence on external oil and fossil fuels and make your energy savings more stable and predictable, especially when the energy requirement is high. Uses batteries to store additional night power

Wide range of Applications

Solar can be used for heating of water, power houses, buildings and even electric vehicles. Aesthetics improve the flexibility of the solar in comparison with older models, e.g. printing, flexibility, solar bars, etc.

Safety and Efficiency

More secure than traditional electricity. The efficiency is always improved to make tomorrow more effective the same solar size that is available today

Government’s financial support

When installing solar panels at home or business, federal and state tax advantages are available. Taxpayers may claim 30% of installation cost with advantages varying from state to state. In addition, the solar power industry provides jobs for solar panel manufacturers and solar plants, helping the economy

Disadvantages of Solar Energy

  • High Initial Investment
  • Uses huge batteries
  • The size of the system is determined by the amount of available space.
  • Limited by a country’s climate
  • Sunlight is required for the best results.
  • Rebates by government may not be there forever
  • Solar panels manufacturing can damage the environment
  • Cannot Be Used At Night
  • Low conversion rate for energy
  • The installed location of solar panels is fixed

High Initial Investment

High material and installation initial costs and long ROI. The initial investment in solar panels is quite high and not everyone can afford it. It covers solar panels, inverters, batteries, wireless systems and plant systems. However, the development of solar technologies is continuing, so that prices can be assumed to decrease in the future.

Uses huge batteries

Solar power is used to charge batteries, allowing the use of solar powered devices during the night. It is often possible to use large, heavy batteries, which take up space and must be substituted occasionally.

The size of the system is determined by the amount of available space.

The space is a major factor in the installation of solar panels. If your roof isn’t big enough, you might have to downsize your system or think about solar.

Solar panels are still quite large products, which means they need to instal a large area. The disadvantage in size means they can’t be placed in small areas and they actually need a big roof.

However, some systems offer flexible roofs designs.

Limited by a country’s climate

The generation of electricity depends entirely on countries which are exposed to sunlight.

Sunlight is required for the best results.

Energy can be generated only when the panel is touched and converted by sunlight. Therefore, no energy will be produced if there is no sun.

Even if solar panels can produce power over cloudy days (because UV light is the source of energy), they are best performed on sunny days.

When not enough of the sunlight hits the panels on rainy days, your panel performance will be adversely affected.

Rebates by government may not be there forever

The government’s incentives and rebates may not last forever. This is another good reason to use these discounts and incentives now.

Because the prices of solar panels become more affordable, the government may reduce the discounts and incentives they offer in future.

Now it is best to jump on the car to make the most of it before it is gone!

Solar panels manufacturing can damage the environment

Although solar panels produce clean renewable energy, they can harm the environment by manufacturing them.

Mass solar panel production may lead to the combustion of fossil fuels and plastic waste.

For solar panels this is a disadvantage, even when they produce green, renewable energies themselves.

Cannot Be Used At Night

Your solar panels are unable to produce energy at night, which means that your solar panels can produce energy only 12 hours a full day. There will be no energy produced without sunlight hitting the solar panels.

This is an adverse factor for solar panels but could be overcome with new technology in the future. There are already discussions about a “anti-solar panel” that can produce electricity at night.

Low conversion rate for energy

Even advanced solar panels only convert 20-25% of the energy in the sun to electricity. It demonstrates how far better technology is needed to maximise the full force of the sun.

However, many things must be considered, such as the direction and position of the panels.

The solar panels of Jinko have a few times claimed the world record.

The installed location of solar panels is fixed

Panels on your roof are installed there pretty much for good.

Without paying for the dismantling, removal and transfer of your system to a different location, Solar panels will be stuck in one location.

Solar systems aren’t at all mobile, which means you have to leave the system behind if you buy solar but decide to sell.
