https://imechanica.org/node/13307
<div class="field field-name-body field-type-text-with-summary field-label-hidden"><div class="field-items"><div class="field-item even"><p> </p>
<p><strong><span>Discussion topic 5:<br />
In recent years, millions of solar panels have been placed on roofs around the<br />
world. Discuss how safe are they? Discuss the hidden pollution caused by solar<br />
panels.</span></strong></p>
<p class="MsoNormal">
<strong><span>The earth is in constant supply of solar power of up<br />
to 100,000TW, this is enough energy to meet the energy needs of the earth’s<br />
population every hour. The solar radiation thus supplied to the earth can be<br />
put to meaningful use by applying the concept/technology of photovoltaics (PV)<br />
– converting solar radiation into direct electricity using semiconductors (monocrystalline<br />
silicon,<span> </span>polycrystalline silicon,<br />
amorphous silicon, cadmium telluride and copper indium gallium<br />
selenide/sulphide) that exhibit the photovoltaic effect and illuminating them<br />
by photons [1].</span></strong>
</p>
<p class="MsoNormal">
<strong><span>Even though PV systems have been known to offer<br />
plentiful energy, the cost of solar energy technology (SET) along the<br />
production line in terms of environmental, accident and associated risk issues<br />
is still high [1]. </span></strong>
</p>
<p><strong><span>ENVIRONMENT<br />
IMPACT FROM SOLAR THERMAL HEATING SYSTEM.</span></strong></p>
<p class="MsoNoSpacing">
<strong><span>Only little amounts of the large quantity of<br />
materials used for production of solar thermal (ST) systems are consumed during<br />
their operation [2]. At the operation stage of solar panels, the safety concern<br />
and exposure to hazards comes as a result environmental pollution from changing<br />
the coolant. A good organizational safety policy/work practice can address this<br />
problem [2]. </span></strong>
</p>
<p class="MsoNoSpacing">
<strong><span>Leakage of the coolant system can cause fire and<br />
gases released from vapourised coolant all constitute a major health and<br />
environmental safety issues [2].</span></strong>
</p>
<p class="MsoNoSpacing">
<strong><span> </span></strong>
</p>
<p class="MsoNoSpacing">
<strong><span>Loss and changes to an existing ecosystem can also<br />
result when large-scale deployment of solar panels is required [2]. Installation<br />
of solar panels can cause water to leak from the roof and at installation, the<br />
workman is faced with the risk of falling from the top of the roof [2]. </span></strong>
</p>
<p class="MsoNoSpacing">
<strong><span> </span></strong>
</p>
<p class="MsoNoSpacing">
<strong><span>The cost components associated with the accident<br />
that may occur are those incurred before occupational injuries, at occurrence<br />
of the accident and that spent on its prevention if properly identified [3].</span></strong>
</p>
<p class="MsoNoSpacing">
<strong><span> </span></strong>
</p>
<p class="MsoNoSpacing">
<strong><span>The pollution associated with the transport and<br />
manufacture of SET are also of considerable significance. Large deployment of<br />
SET proves to have effect on health because of the emissions involved in<br />
material processing, the chemicals involved in the batteries that are used as<br />
well as the raw materials needed for their production [2]. Heat transfer fluids<br />
such as water, oil and liquid sodium are involved in SET, accidental release of<br />
any of these fluids can cause occupational hazard [2].</span></strong>
</p>
<p class="MsoNoSpacing">
<strong><span> </span></strong>
</p>
<p class="MsoNoSpacing">
<strong><span>The equipment for solar energy conversion requires<br />
solar cells which in turn require the use of heavy and rare earth metals, and<br />
the risk of pollution is inherent in their mining, manufacture, construction<br />
and disposal after the useful life of these assets. </span></strong>
</p>
<p class="MsoNoSpacing">
<strong><span> </span></strong>
</p>
<p class="MsoNoSpacing">
<strong><span>On September 19, 2012, a village in eastern china<br />
rioted against a local solar panel manufacturing firm for dumping harmful and<br />
toxic chemicals into its river [4]. Thus, the illusion of green, clean energy<br />
only transfers/exports environmental ruin and damage to countries/places where<br />
the panels are manufactured. This can be classified as a form of risk control<br />
strategy –risk transfer [3].</span></strong>
