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.
Solar energy pros and cons: Solar thermal systems by Dino Green on December 29, Solar energy systems are classified into three system categories: In this article we review the operation of Solar Thermal technologies and identify the main Advantages and Disadvantages of Solar thermal systems.
Solar Thermal Technology Systems Solar Thermal systems constitute an important renewable green energy technology by exploring the naturally renewable energy of the sun. Solar Thermal systems use thermal energy absorbed by sun radiation heat and use it to heat up water or other medium e. This Thermal energy contained in the material at high temperature can be used for a range of applications such as: For providing hot water in buildings HW for use For heating of buildings and spaces solar heating systems For cooling of buildings and spaces solar cooling systems For the generation of electric power Power Industry ; such systems are called Concentrated Solar Thermal CSP The basic operation of solar thermal systems incorporates a means of absorbing solar radiation by different technological applications.
In general the solar collectors may be flat plate collectors or evacuated tube collectors examples of which are typically seen on building roof tops with a hot water storage tank. In CSP systems, used for electrical power generation, different applications exist such as Power towers, parabolic dishes or parabolic troughs.
These solar thermal systems use different technological configurations to gather solar energy in the form of heat. It is normal to expect a variation of performance levels amongst the different configurations in terms of efficiency, environmental impact and cost.
In conjunction to other energy systems using renewable or non-renewable energy sources solar thermal systems can offer several advantages.
Advantages of Solar Thermal Systems As all renewable green energy technologies, Solar Thermal Systems, contribute to reducing consumption of fossil fuels.
Solar collectors used for heating are a mature technology offering a high energy contribution at a fairly low cost.
That is why solar thermal systems have formed an established norm in the construction industry. Solar thermal systems exhibit in general high efficiency levels when it comes to solar heating applications.
In combination to their moderate costs they offer a good return on investment at short repayment periods. Depending on environmental conditions repayment of initial investment is expected within first five years; in cases of available subsidy funding repayment is even earlier.
Moreover, solar systems can easily store thermal energy by use of storage tanks and use it when it is required without interference from immediate environmental conditions; e. This is especially important in power generation with concentrated solar power plants CSP.
Concentrated Solar technology is particularity suitable for Power generation because it makes it possible to reach very high temperatures. High temperatures can supply a steam turbine to produce electricity without the consumption of fossil fuels. In general, solar thermal panels can easily be used in a modular manner and on a wide range of technological configurations.
As a renewable green energy source they are expected to grow even further with a higher contribution in the global energy mix. As in everything in real life, solar thermal systems also have disadvantages. Disadvantages of Solar Thermal Systems Although we have noted that storage tanks are an important advantage which can be used to provide for an uninterruptible energy supply, the fact that sun only shines during the day is an inherited disadvantage for all solar energy systems.
Depending on the place of installation and environmental conditions, seasonal variation of solar radiation may be of high influence to the reliability of a solar system. For power generation it is important to note that CSP systems come at large scales of about MW or larger, thus they involve an extremely high initial cost.
At Energy Matters, we want young Australians to be as inspired by solar as much as we are to ensure the good work already being done in moving towards Australia’s renewable energy future continues. Solar is a capturing the sun rays, converts and stores its electrical energy. Here you know about solar energy advantages and disadvantages. In this video lesson you will understand how water can be used to generate electrical energy. You will also identify some benefits and drawbacks.
Consequently, economical viability of concentrated solar power CSP will continue to remain a main disadvantage before costs can be reduced, or before costs for alternative energy solutions increase e.
In review of the advantages and disadvantages of solar thermal systems it is important to understand that pros and cons are variable attributes depending on comparable alternatives available and on other external factors — see the ultimate list of solar energy pros and cons.Disadvantages of Solar PV – in a nutshell.
As in all renewable energy sources, solar energy has intermittency issues; not shining at night but also during daytime there may be cloudy or rainy weather.

Here are 5 major advantages and disadvantages / pros and cons of solar energy: Solar Energy Disadvantages – The Cons #1. Solar Energy is expensive. In this video lesson you will understand how water can be used to generate electrical energy. You will also identify some benefits and drawbacks. Here are 5 major advantages and disadvantages / pros and cons of solar energy: Solar Energy Disadvantages – The Cons #1.
Solar Energy is expensive. Solar trackers are rising in popularity, but not everyone understands the complete benefits and potential drawbacks of the system. Solar panel tracking solutions are a more advanced technology for mounting photovoltaic panels.
