Benefits of Solar Energy

What are the Advantages of Solar Energy?

Solar energy is derived from the sun’s radiation. The sun is a powerful energy source, and this energy source can be harnessed by installing solar panels. Did you know that the energy it provides to the Earth for one hour could meet the global energy needs for one year? However, we are able to harness only 0.001 percent of that energy.

There is a reason why solar energy has become atrending topic when talking about renewables. While it has been widely criticised for being expensive or not very efficient, solar energy has now proved to be extremely beneficial -not only for the environment but also financially speaking.Thanks to various solar panel grants as well as the ever-increasing higher demand, the technology has been improved considerably and has been complemented by solar battery storage systems, turning into a significantly more efficient source of clean energy.

Advantages of Solar Energy

1. 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.

2. Reduces Electricity Bills
Since you will be meeting some of your energy needs with the electricity yoursolar systemhas 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, there is also a possibility to receive payments for the surplus energy that you export back to the grid. If you generate more electricity than you use(considering that your solar panel system is connected to the grid).

3. Diverse Applications
Solar energy can be used for diverse purposes. You can generate electricity (photovoltaics) or heat (solarthermal). 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.

4. 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. If in doubt, you can always rely on specialised cleaning companies, which offer this service from around £25-£35. Most reliable solar panel manufacturers offer 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 be changed after 5-10 years because it is continuously working to convert solar energy into electricity and heat (solar PVvs. solar thermal). Apart from the inverter, the cables also need maintenance to ensure your solar power system runs at maximum efficiency. So, after covering the initial cost of the solar system, you can expect very little spending on maintenance and repair work.

5. Technology Development
Technology in the solar power industryis 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.

Solar Batteries – The Evolution of Your Storage System
It’s common to face some confusion when first determining your solar battery storage system costs. Some of the major contributors to solar battery costs are the chemical materials that make up the battery, the life cycle of the battery, the storage capacity, and the usable capacity.

Why Do You Need a Solar Battery Storage System?
Coupling solar batteries with solar arrays is a relatively new practice. The advantage of doing so is four-fold. First, a solar battery stores the energy generated during sunlight hours and makes it readily available for use during non-production hours, such as at night or on cloudy days, essentially enabling your home to run on 100% renewable solar energy around the clock, as long as electricity demand does not exceed the supply that the battery can provide.

Second, a solar battery storage system can lower your energy costs significantly. By charging the solar battery during off-peak hours and discharging it during peak hours,you can avoid paying a lot for electricity from your utility company. The savings from this can serve towards reducing your solar battery system costs.

Third, you can earn money by selling the energy stored in your solar battery back to the electrical grid when electricity prices are at their highest—if your utility allows net metering. Lastly, by adding a solar panel battery to your solar system, you can choose to be independent from the national grid at any time, thereby ensuring energy security for your household.

❖Energy storage as a support for (fast) charging infrastructures

Several millions of Electric Vehicles (EVs) are expected to be sold in Europe by 2025. Most EVs are and will be mainly recharged at home or at work, but charging stations open to the public will be necessary to avoid present range anxiety and to offer new services that will help EV market share penetration and extend EV trips.

Hundreds of thousands of charging infrastructure points have been rolled out throughout Europe, including thousands of 50 kW fast chargers15. In order to prepare for the short term arrival of very high range EVs on the market, brand-new high power fast charging infrastructures are being designed and deployed: power levels ranging from 150 kW to 350 kW per EV charging point will be requested to rapidly charge these new generations of EVs.

The total power demand at the grid interface will spread from 350 kW to 1 MW or more depending on the station configuration. The impact of the charging infrastructure development on the electrical grid will be very substantial, both in terms of power demand and grid investment16. Energy storage systems can be used to mitigate the impact of such EV development on the electricity network and to increase RES penetration levels in the transport sector by being connected to charging points.

-Energy storage systems can charge electricity from the grid at times of low demand and discharge at times of high demand. They can also avoid/defer costly grid reinforcements for DSOs and TSO sespecially in remote locations such as rural areas18.

-Energy storage systems increase RES penetration levels in the transport sector, with minimised curtailment and at optimised system cost, by storing renewable energy when there will be excess of sun or wind power and by discharging at times where sun will not shine and wind will not blow. Energy storage technologies coupled to EV chargers would also enable multiple vehicles to be charged at the same time, with power being supplied both by the grid and local RES.
