Using solar power is an eco-friendly way of catering
to the requirement of energy across the world. Solar photovoltaic (PV) panels
are among the primary renewable energy-based power generation technologies. The
solar panels are installed on free land or on rooftops. However, a major
drawback of these solar PV systems is that they occupy large land area and
various parts of the world do not have such kind of space where these systems
can be installed, thereby restricting the deployment of solar PV systems on a
large scale. But now with the emergence of the floating solar panel technology,
these problems can be taken care of easily. Floating solar panel makes use of
water surface for installation of solar panels, therefore, floating solar power
plants can be installed on lakes, reservoirs, ponds, rivers, and sea.
The floating solar panels have various
advantages over land-mounted solar panels, such as increased efficiency because
of the cooling effect of water and evaporation control. Apart from this, the
installation of these systems requires no heavy equipment or tools, the
construction materials utilized are recyclable, and evaporation control saves
water which can be utilized for irrigation and drinking. Because of all these
advantages, various governments across the world have initiated different
schemes and projects for the promotion and encouragement of using technologies,
such as floating solar panel, for generating renewable energy. Various
countries, including the U.S., France, Japan, the U.K., Brazil, and India, have
started focusing on developing floating solar power plants. Moreover, some of
these countries are even providing tax benefits and subsidies to the solar
panel manufacturers. There are two types of floating solar panels, namely
solar-tracking floating solar panels and stationary floating solar panels.
Among these, the stationary floating solar panels were more popular.
Among all the major regions, including Asia-Pacific
(APAC), North America, and Europe, APAC witnessed the highest adoption of
floating solar panels. This was due to the heavy investment made by the key
solar panel manufacturers for developing floating solar panels and the
increased support provided by governments for floating solar power projects.
For example, in April 2015, the construction of two mega floating solar power
plants was completed at Higashihira Pond and Nishihira Pond in Kato City, Hyogo
Perfecture, Japan. These plants are designed to produce 3,300 megawatt hours of
electricity per year.
