Renewable energy design in Asia 3
Introduction to renewable energy.
Renewable energies are form of energies that are natural inexhaustible however in limited supply over a
period of time. There are different types of renewable energy that are already in exploitation, credit to
advancement of technology over the recent years. Among available renewable energies includes wood,
solar energy, biogas, wind, hydropower and geothermal power. It is without no contradiction that
renewable energy is playing major roles in energy sector transforming lives of humankind. For instance,
wood was used for heating and providing light until the mid-1800s in the United States. For the ages,
hydropower and biomass, until 1990s, were their main source of energy. Revolution in technology has
made it possible for exploration of wind and solar power that is a share in the energy sector of US
(Eia.gov, 2019). Main advantages of renewable energy over non-renewable energy is their ability to
sustain power supply over a long period of time without getting exhausted. This type of energy is free in
nature, therefore, the operational cost is at a lower rate compared to generating utilities that uses fossil
fuel such as diesel generator. In addition, renewable sources of energy are most recognized source of
clean energy as they produce no hazardous carbon oxide gases into the atmosphere (Ayres, 2019). It
largely relies on technology that can be modified depending on the capacity power demand. Continuous
emission of carbon dioxide into the atmosphere relatively pollutes the environment.
Renewable Energy Information in the world and Asia
In this report, solar energy system in the world and Asia has been studied extensively. In solar energy
technology, photovoltaic cells in the panels convert sun rays into electricity using energy of the photon.
The system cascaded down to produce refined a.c or and d.c power depending on the type of the load.
Solar panels are manufactured in large volumes from manufacturing plants at suitable economic scale.
Therefore, as a result, solar energy has been extensively deployed in all scales globally. They are
designed either to operate in off-grid or on-grid depending on the country’s energy policy and quantity
generated.Studies have forecasted that China has risen to the occasion globally by decarbonizing their
energy generating utilities. It has since surpassed European Union by becoming largest consumer of
renewable energy.
PV solar energy generated in the world.

From the bar graph above obtained from “International Energy Agency”, China having installed many
solar PV power plant is the leading in production of solar energy. The rising trend as from the year 2017
has been projected until the year 2023. In Asian countries, the graph shown below shows capacity of
generated renewable energy in Asia.
SOURCE (Nikkei Asian Review, 2019)
New JRC PV 2018 status reports that solar power attracted the bigger share of new investments funds in
renewable energies. For instance, EUR140billion that was globally invested in solar energies accounted
for almost 60% of the global investments in renewable energies. The newly solar PV installed capacity
proportionally increased by 32% amounting to almost 100GW as in the year 2017 (Phys.org, 2019). This
values globally represents approximately 2% of the total energy produced in the world. Utility- scale
application accounts for over 60% of the total solar power generated while the remaining percentage is
utilized in off-grid system such as residential and commercial power system. The graph below shows total
solar energy production as from the year 2017 and the projected capacity (Iea.org, 2019). The graph
below shows worldwide consuming power of solar energy.

SOURCE (Ritchie and Roser, 2019)
From the graph above, obtained from “BP Statistical Review of Global Energy” Asia was leading in
consumption of solar energy by a magnitude capacity of 146TWh in the year 2016.
Asia amounts to more than a half of the energy consumed globally. 85% of the energy consumed in Asia
comes from fossil fuels. Rising demand of the energy has resulted to rapid development of renewable
energy is Asia potentially to boost urbanization and industrialization which heavily depend on energy.
(Irena.org, 2019). According to International Renewable Energy Agency, renewable energy generated in
Asia accounted for almost two-third worldwide (Nikkei Asian Review, 2019).
SOURCE (Nikkei Asian Review, 2019)
Asia was capable of producing 918 gigawatts of renewable energy with China and India contributing a
bigger share as in the year 2017. From the chart shown below, Asia cumulatively contributes the highest
percentage of installed solar capacity in the world.

For instance, China alone, having installed 130GW of solar power, contributes to nearly a half of globally
installed capacity. India is reported to contribute to about 10% of renewable energy globally from the data
of 2017. India generated 82GW of solar energy. Japan, seemingly, is the third largest in Asia with
production capacity of over 19GW of total capacity worldwide with its solar energy recording 96%
increase as in the year 2017.
Solar energy capacity rose to 32% in the year 2017. Rapid and fastest growth can be accredited to
simplified installation and operation of solar power plant as compared with other sources of renewable
energy. On addition, solar energy is cost competitive with fossil fuels (Nikkei Asian Review, 2019).
Design of Smart Solar system
Solar panels are mounted on programmed motorized pivotal motor on panels for maximum tracking of
the sun rays. The mechanism ensures panels capture maximum power from the sun that could have been
limited by angle of incident onto which sun rays strike surface of the panel.
Monocrystalline panels of high efficiency and improved technology have been used in the design. To
minimize effects of shadings, panels with inbuilt by-pass diodes have been recommended. Shading have a
great impact especially of panel array operating under high voltages. Shaded panels behaves like a semi-
conductive impedance that could slow of block current in cells connected in series.

Controllability of the plant can be effected remotely by use of remote control and cloud server. Remote
control improves efficiency and reliability of the protective scheme in case of a fault. Protective scheme
comprises of fuses, circuit breaker and robust Surge Protective Devices (SPD). The protective scheme can
be controlled on-site and remotely.
