maintenance of the solar panels due to dust accumulation and atmospheric calamities like thunderstorm, heavy winds and heavy snow-ball falls. Solar energy is not a
continuous source. During nights, it is very difficult to maintain performance of the
biogas generation unit (Mahamudul et al. 2019).
There are other problems that reduce the performance of the Solar Collector based
systems. These can be overcame by routine and timely look-after and maintenance.
3.4 Improvement of the Performance of Solar-Based Power
Units/Set Ups
The methods that may increase the efficiency of the solar based power units are as
dictated follows.
(1) In order to pick the power plant performance up, dust accumulation on the
reflecting surfaces need to be prevented, by regular dry/wet cleaning. Since, it
is observed that the glass plates transmittance reduces by 39.4%, on an average
on account of exposure to the solar radiation for say about 38 days. Super-hydrophobic materials are specifically recommended to inherit the self-cleaning and
anti-contamination properties in the concentrating solar power mirror (Xu et al.
2016).
(2) The heat transfer fluids which are thermally more stable even at higher temperatures also mend the solar energy system’s performance. The requirement
of pumping power reduces for lesser viscous heat transfer fluids. The sizes of
thermal energy storage tanks can be mitigated by using working fluids having
higher values of specific heats. These two factors help increasing the efficiency
of a solar collector system (Xu et al. 2016).
(3) The performances of solar systems can also be improved by replacing the aluminium concentrator by galvanized steel structure. In addition, Aluminium
polymeric reflector be replaced by thin-silvered glass reflector and by providing selective surface coatings on the absorber surface of a receiver in a way
to improve the outcome of the system. A practice of using of steel and thin
glass reflector also raise the performance of the system by about 12% that may
diminish the cost of energy to be supplied by about 25% (Njoh et al. 2019).
(4) The use mirrors having high reflective qualities allow more than 98.5% reflectivity to the solar rays incident on the reflector surface, also assist enhancing the
system performance (Price et al. 2002).
3.5 Concluding Remarks
In order to cope up domestic energy poverty, the developing countries should keep on
high priority an access to electricity to each and every remotely located region. It may
