advantages and disadvantages of solar energy: can solar technology overcome three big drawbacks? - electrical energy storage systems
Considering the conversion of solar thermal energy to electric energy and photovoltaic, here are some shortcomings and how to solve them: 1)
Solar energy can only be used during the day, and the impact of climate change or geographical location is a big problem.
The availability of solar energy during the day is a difficult fact and could be a trade --
Given that solar energy is available to everyone for free.
Power plants adapt to this fact by using solar energy during peak or off peak periods
Peak times of the day according to weather conditions and electricity demand.
Another option is to provide hot storage for use at night or during peak/off peak periods
Peak hours of the day. 2)
Energy Conversion rate or efficiency is low compared to other energy sources.
Low energy conversion rates for solar thermal power generation and photovoltaic power generation are being addressed through increasingly enhanced R & D activities by key companies --
Efficient Materials and costs-
Centered on solar systems or facilities.
In addition to turning to highly efficient solar cell materials, another way to mitigate this inefficiency problem is to develop solar applications that require less power.
In addition, another method is to improve the efficiency of solar storage using efficient batteries.
Ideally, these efficiencies
The cost is also increasing.
Opportunities for reduction should be combined to achieve the best results in the use of solar energy. 3)
High capital cost requirements for purchasing or producing materials and installing solar systems or facilities.
This high capital cost requirement is offset by the following:)
Use cheap barren land not affected by climate change, which usually has clear weather conditions throughout the year, new building designs for solar facilities and houses, and incorporate solar panels into the photovoltaic field.
In design, fixed or fixed facilities are suitable for solar panels with architectural style.
As technology advances, the installation of solar panels will now become less troublesome. b)
Reduced operating costs considering that solar energy is free.
The only limiting factor is that although solar energy is free, availability is limited by half a day or less in addition to climate factors
Issues related to preventing peak power generation.
In addition, due to the low conversion efficiency, this means that more solar modules will need to be installed to increase the available power. c)
Reduce harmful effects on the environment (
Reduce carbon emissions)
Compared with other energy sources such as crude oil.
There is no doubt that we can say that solar power is eco-friendly.
Don't worry about carbon emissions.
In addition, the installation of solar panels does not require too many strict prerequisites or requirements.
The only key issue is to get the best power of PV, which requires a good tracking mechanism to achieve the correct position of the sun's direction when the sun moves from east to west.
The more automated the tracking mechanism is, the more efficient the installed system will be.
With no major complications, trouble shooting and preventive maintenance measures will not be very difficult.
The potential problems that may eventually arise will be natural phenomena or damage caused by human beings. made accidents. d)
Reduce dependence on imported crude oil.
The most critical issue of oil dependence is the volatility of oil prices, which affects most of the world's economic markets.
Therefore, as renewable energy sources such as solar energy provide electricity, the dependence on imported crude oil is reduced.
However, there are limitations in the application of solar energy.
The challenge is to identify which applications need to maximize potential savings or reduce costs.
In addition, recent developments have shown that some key companies have improved the manufacturing capacity of solar panels.
This will ultimately reduce the unit cost of producing high-efficiency silicon photovoltaic.
Solar panel production companies have increased production as demand increases.
With the increasing complexity of technology, the application of solar energy is becoming more and more extensive.
No matter how difficult these key companies are to produce solar energy or other forms of renewable energy, the advantages are far greater than the disadvantages.
As the world waits for the coming of the energy revolution, researchers must take the time to further develop solar energy. ReferencesU. S.
