Advantages of Solar Energy

SOLAR ENERGY

What are the Advantages?

Renewable Energy Source

Among all the benefits of solar panels, the most important thing is that solar energy is a truly renewable energy source. It can be harnessed in all areas of the world and is available every day. We cannot run out of solar energy, unlike some of the other sources of energy. Solar energy will be accessible as long as we have the sun, therefore sunlight will be available to us for at least 5 billion years when according to scientists the sun is going to die.

Solar power helps to slow/stop global warming

Global warming threatens the survival of human society, as well as the survival of countless species. Luckily, decades (or even centuries) of research have led to efficient solar panel systems that create electricity without producing global warming pollution. Solar power is now very clearly one of the most important solutions to the global warming crisis.

Solar power provides energy reliability.

The rising and setting of the sun is extremely consistent. All across the world, we know exactly when it will rise and set every day of the year. While clouds may be a bit less predictable, we do also have fairly good seasonal and daily projections for the amount of sunlight that will be received in different locations. All in all, this makes solar power an extremely reliable source of energy.

Solar power provides energy security

On top of the above reliability benefit, no one can go and buy the sun or turn sunlight into a monopoly. Combined with the simplicity of solar panels, this also provides the notable solar power advantage of energy security. Especially in times where most of the fossil ressources are in political instable contries (Venecuela, Iraq, Iran), or hold by monopolies like OPEC putting money into the development and installation of solar power systems makes sense.

Solar power provides energy independence

Similar to the energy security boost, solar power provides the great benefit of energy independence. Again, the “fuel” for solar panels cannot be bought or monopolized. It is free for all to use. Once you have solar panels on your roof, you have an essentially independent source of electricity that is all yours. This is important for individuals, but also for cities, counties, states, countries, and even companies, eg. Ukraine in recent years has saved approximately $3 billion in reduced oil and gas imports from Russia thanks to the solar power plants.

Reduces Electricity Bills

Since you will be meeting some of your energy needs with the electricity your solar system has generated, your energy bills will drop. How much you save on your bill will be dependent on the size of the solar system and your electricity or heat usage. Moreover, not only will you be saving on the electricity bill, but if you generate more electricity than you use, the surplus will be exported back to the grid and you will receive bonus payments for that amount (considering that your solar panel system is connected to the grid). Savings can further grow if you sell excess electricity at high rates during the day and then buy electricity from the grid during the evening when the rates are lower.

Diverse Applications

Solar energy can be used for diverse purposes. You can generate electricity (photovoltaics) or heat (solar thermal). Solar energy can be used to produce electricity in areas without access to the energy grid, to distil water in regions with limited clean water supplies and to power satellites in space. Solar energy can also be integrated into the materials used for buildings. Not long ago Sharp introduced transparent solar energy windows.

Low Maintenance Costs

Solar energy systems generally don’t require a lot of maintenance. You only need to keep them relatively clean, so cleaning them a couple of times per year will do the job. Most reliable solar panel manufacturers give 20-25 years warranty. Also, as there are no moving parts, there is no wear and tear. The inverter is usually the only part that needs to changed after 5-10 years because it is continuously working to convert solar energy into electricity (solar PV) and heat (solar thermal). So, after covering the initial cost of the solar system, you can expect very little spending on maintenance and repair work.

Technology Development

Technology in the solar power industry is constantly advancing and improvements will intensify in the future. Innovations in quantum physics and nanotechnology can potentially increase the effectiveness of solar panels and double, or even triple, the electrical input of the solar power systems.
