Strengths of Construction of Solar Energy PV Panel
The current global scenario has contributed towards exploitation of renewable energy resources and emissions of harmful gases such as Greenhouse gases (Weitemeyer et al., 2015). The gases are harmful due to the fact that the released gases are absorbed by the atmosphere on the Earth to warm the atmosphere at an extreme level. The gases are toxic which can endanger human life, animals and aquatic life on Earth (Zou et al. 2017). The world’s energy demand is growing rapidly and to meet their requirements different countries has established strategies for effective use of renewable resources (Kannan and Vakeesan, 2016). The renewable energy sources contributing 13% of the total energy development including bio-fuel, solar, wind, hydro, geothermal and others (Hosenuzzaman et al., 2015). However, the main energy sources in use are fossil fuels which are the main sources of emission of carbon dioxide resulting in global warming (Hosenuzzaman et al., 2015). The PV panels are the most useful technology in the construction industry where installation of PV panel is growing and so the market share and job positions in construction industry are also growing (Zou et al. 2017).
The key resources for large scale renewable energy resources are wind and solar energy (Breyer et al., 2017). The solar energy PV panel construction is the major technology in the recent scenario adopted by major countries such as Poland, Britain, Turkey and other countries (Breyer et al., 2017). Hence there is a need to use solar energy PV panel construction which is described as converting the solar energy directly into electricity for residential and commercial purposes (Sampaio and González, 2017). The solar energy is paving ways for construction industries in a way that with growing rise of PV panels, there is growing necessity of its installation (Koo et al. 2017). Thus construction industry is growing in this aspect were the cost of each panel decreases and open opportunities for constructing PV panels in every building whether existing or newly constructing.
The construction of solar energy PV panel for buildings contributes to various strengths which are described in the following paragraph.
The deployment of PV panel is determined by crystalline silicon wafer-based technologies while building construction (Jean et al., 2015). This technology provides benefits of high power conversions, determined manufacturability and ample materials. The silicon based PV technology systems are modular which shows its strength of linking modules together to provide power from watts to tons of megawatts while deployment (Ellabban, Abu-Rub and Blaabjerg, 2014). The solar energy PV panel module has 10% overall efficiency which has manufacturing cost of $1/Watt (Aman et al., 2015). This has resulted in economic growth of PV panel construction. According to Li et al., 2015, the minor social impacts of solar energy PV panel construction is also a factor which makes it most favourable. The government subsidies and incentives in the construction of solar energy PV panel construction for residential commercial buildings (Li et al., 2015). There are environmental benefit from installing PV panel as it reduces the harmful gases released in the atmosphere where there is only room for sunlight usage (Koo et al. 2017). The solar energy PV panel is the most useful technology where it can never exhaust as its main source is sunlight (Smith et al., 2014). The materials needed to convert sunlight into electricity are solar panels, inverter, net meter, silicon cell, metallic electrodes and fused array combiner consisting of PV cables (Hansen and UNEP 2017). The solar energy PV panel has higher penetration level in the PV smart grid which helps in ensuring security and economic integration of the energy development (Wan et al., 2015). The PV smart grid is a system which supports energy flow in a bi-directional form that has no geographical boundaries. The smart grid is reliable and maintains the ratio of generating renewable energy to total energy (Sampaio and González 2017). The power generation of the PV panel is high and its demand is huge in the current scenario which makes it a most reliable energy resource (Breyer et al., 2017).
Weaknesses of Construction of Solar Energy PV Panel
The construction of solar energy PV panel for buildings contributes to some weaknesses that are discussed in the following paragraph.
The government subsidies and incentives are required to be embarked taking up solar energy installation in construction industry for constructing commercial and residential buildings (Bhandari et al., 2015). There is high cost of capital and spaces for establishing grid systems and utility plant for residential and commercial purposes which poses challenges for construction industry (Talavera et al., 2015). The construction of solar energy PV panel contributes to distributed system designs which cause base load difficulties in the deployment for constructional professionals (Sun et al., 2014). The major weakness is that till now the research and development of projects simulation designs for shaded conditions are not yet taken up by the construction industry (Bhandari et al., 2015). The sunlight is the main source of the solar energy PV panel however sunlight source is not available at night which is the major disadvantage (Kouro et al., 2015). The availability of solar energy in bad weather conditions is not possible which results in major disadvantage of PV panel construction for construction industry (Sun et al., 2014). The solar energy PV panel produces direct current which requires use of an inverter (Li et al., 2015). The awareness of solar energy PV panel construction is huge in urban and populated areas however in remote areas the technical support lacks (Breyer et al., 2017). The solar energy PV panel construction is more frequent to people who are aware of it (Kannan and Vakeesan, 2016). This shows that there are some areas such as construction industry which require improvement.
The construction of solar energy PV panel for buildings has some opportunities that can be looked upon are discussed in the following paragraph.
The construction of solar energy PV panel is the ultimate target of the Federal Government to achieve in the coming future (Ondraczek, Komendantova and Patt, 2015). This shows that there are huge demands of solar energy PV panel across the world (Smith et al., 2014). The solar energy PV panel developers in construction industry easily get statutory and clearances on the PV panel construction (Jean et al., 2015). The smart grid connection is a thrust for establishing in buildings which enhances security and integrity around the building and surroundings (Sampaio and González, 2017). This will ensure sustaining of smart grid in any condition such as bad weather which will grow its importance in construction industry (Hansen and UNEP 2017). The more companies entering into the market of constructing solar energy PV panels for buildings may lead to reduced cost across the globe (Wan et al., 2015). The construction of solar energy PV panel will contribute to better economy and reduction in harmful gases through the use of fossil fuels (Kouro et al., 2015). Therefore, these areas should be considered to make the solar energy PV panel construction more valuable.
Opportunities of Construction of Solar Energy PV Panel
The construction of solar energy PV panel for buildings poses threats that are discussed in the following paragraph.
The threats are basically related to the cash flow in off-peak seasons such as rainy season and bad weather conditions (Hosenuzzaman et al., 2015). There are dearth of skilled professionals for solar energy PV panel construction in some parts of world (Kouro et al., 2015). There are high risks involved with the construction of solar energy PV panel as it converts solar energy directly to electric (Jean et al., 2015). The solar PV panel’s installation poses risks of electrical situations where electrical risks can occur such as electric shock (Heiskanen, Nissilä and Lovio 2015). This direct conversion can be dangerous as it can have negative impact on anyone (Sampaio and González, 2017). The solar energy PV panel has an alternative which is also considerable and has similar specifications as solar energy and that is wind energy (Kannan and Vakeesan, 2016). The construction industry will be impacted as small mistake in deploying PV panel can damage property in case of new building construction harming workers (Heiskanen, Nissilä and Lovio 2015). The fire is another threat which can occur in PV panels. The wind energy alternative is also a threat to the construction of solar energy PV panel construction across the world.
