Solar energy is renewable energy that is a result of the radiations of the sun. It is among the most renewable and major sources of energy on earth. The sun itself produces such enormous quantity of energies in the shape of electromagnetic radiations and this energy can be harnessed and converted using some technologies into forms that can be utilized to generate electricity or harnessing heat. Solar energy can take any of two dominant forms, that is, photovoltaic (PV) and solar thermal. A type of photovoltaic device that directly converts sunlight to electricity is known as a photovoltaic system. Sunlight falling on these panels provides power in the form of electric current by a process known as photovoltaic effect. These systems are typically applied in housing rooftops, solar farms and transportable solar gadgets. Conversely, solar thermal systems only maintain sunlight by focusing using mirrors or lenses and extracts heat and uses it to steam generating electricity or domestic sectors by offering direct heat. The exploitation of solar energy has received considerable attention with the reason being; that solar has environmental advantages and has the capacity of reducing reliance on fossil energy. In contrast to the traditional sources of energy, solar energy does not produce neither greenhouse gases, nor pollutants as there is no production process that accompanies the use of this energy source. Also, the development of new solar panels, energy storage devices, and governmental policies contributed to the increased availability of affective solar energy and its affordability. The importance of solar infrastructure is so high that countries all over the world are investing in this field to satisfy the increasing energy needs sustainably and fight with climate change.

Recent Development

• One of the last stages of the observatory's construction was the installation of solar panels on NASA's Nancy Grace Roman Space Telescope on June 14 and 16. These panels, together known as the Solar Array Sun Shield, will power and shade the observatory, allowing for all of the mission's observations and assisting in the cooling of the instruments. The six panels that make up the Solar Array Sun Shield are all coated in solar cells. Once Roman is in orbit, the remaining four panels will swing up to line up with the centre panels, while the two centre panels will stay attached to the outer barrel assembly, which is the outer shell of the observatory. To give the observatory's electronics a consistent supply of power, the panels will face the Sun for the duration of the expedition.

Market Dynamics

Drivers

Technological advancements and the increasing popularity of solar energy as a renewable source of power – The development of solar technologies with a specific reference to photovoltaic (PV) cells, which has achieved remarkable success in terms of efficiency, durability, and cost-efficiency is among the major, internal set-forces. The creation of more efficient processes of manufacture such as monocrystalline panels and bifacial panels has allowed solar energy systems to be more reliable and effective than ever. At the same time, the recent drop in the prices of the solar components, including solar panels, inverters, and mounting systems, has had the effect of a sharp fall in the total price of the whole systems, making the solar energy available to a larger market base. Moreover, the improvement of energy storing technologies like lithium-ion batteries has been possible to gather the surplus solar energy to use within the times it was not sunny and solve the problem of intermittency and make solar systems more reliable. The level of investment into the solar installation by homeowners, businesses, and industrial users to minimize the use of traditional grid supply power and hedge against the fluctuation of electricity cost is growing. This also provides energy security particularly in hard to reach or underserved areas. In addition, solar energy systems, as well as being highly scalable through varying per-capita demands, can be highly modular and therefore be deployed on all levels, including rooftop residential, to large-scale utility solar farms. Finally, the cost of operation and maintenance is low, with long life duration of the solar installation bringing in tempting returns with time.

Restraints

Technical and financial limitations – Regardless of the huge disparity in prices experienced over the years, the use of substantial amounts of money up-front to buy and install the solar panels, inverters, and other devices necessary is still the key hindrance to many consumers and businesses. This upfront cost is prohibitory. The second important limitation is the intermittent nature of the solar energy production that relies greatly on weather conditions, time, and seasonal fluctuations. These fluctuations cause random production of power thus it becomes hard to depend completely on solar energy without proper storage systems. Even though battery technologies are on the rise, the existing energy storage systems are costly and have rather little storage capacities, unable to be readily used and influence the general reliability of a solar source. Also, the physical space of a solar installation needs substantial space especially the mass scale solar farms these are difficult to give in and around urban regions due to the compact urban region and scarcity of lands. Efficiency of solar panels is another constraint: although efficiency keeps rising, given current rates, many of the panels only capture a subset of sunlight, and transform it into electricity only, thus lowering its output in regions that are not as sunny.

Opportunities

Supportive government policies and incentives – Government policy and incentives are among the most important of drivers. Solar power has been subsidized, but to varying degrees, by many countries through feed-in tariffs, tax credits, net metering and subsidies. These friendly policies reduce the upfront financial burden, enhance the growth of solar projects being undertaken by homeowners, companies and utilities. Moreover, environmental guidelines and international climate treaties, which include the Paris Agreement, fascinate countries to decrease their carbon emissions, so the movement towards clean sources of energy, including solar energy, increases. Number one among the factors is the increasing costs of electricity that act as a critical factor in propelling consumers to solar energy. Solar power is a form of energy that is affordable as the rates of utility rise, and it has the capacity of saving long term energy bills especially in those places that have high energy rates and incidence of sunlight. Rising awareness and concern on climate change and green issues also increase the demand of solar energy. People and companies are becoming more conscious of matching their energy consumption engagements with overall sustainability priorities, which led to increased investment into renewable energy infrastructure. In addition, the trend of fast conducting urbanization and industrialization in the developing economies like India and China is generating serious intensity in evolution that the traditional fossil-based power production cannot supply in a sustainable manner. The increasing demand can be served by solar energy because it is scalable and environmentally friendly.
