The rapid expansion of solar photovoltaic (PV) systems is a result of the growing need for sustainable energy. PV systems are a desirable alternative for lowering carbon footprints since they directly transform sunshine into power [1]. The widespread use of PV systems is hampered by a number of issues, despite their enormous potential. We now outline some of these difficulties and provide potential ways to get beyond them. The difficulties and the suggested solutions are presented side by side.

The challenges vis-a-vis our proposed solutions are briefly presented here.

Expensive Upfront Expenses

The challenges with huge costs of initial upfront payments for their deployments and installation could be ameliorated via the following solutions:

Financing Models: A wider range of people can have access to solar installations courtesy of creative financing models like community solar projects, power purchase agreements, and solar leasing. Customers can take advantage of solar energy with these solutions without having to pay for it all up front [2].

Strategies for Cutting Costs: Labour expenses can be decreased by creating standardized designs and installation techniques. Furthermore, local production of solar components can reduce shipping costs and generate employment locally [3].

Energy Storage and Intermittency

Battery Innovations: New battery technologies such as lithium-sulfur, solid-state, and flow batteries offer longer lifespans, faster charging times, and higher energy densities. The intermittency and energy storage issues related to solar and PV systems would be greatly alleviated by these developments in battery innovation designs [4].

Systems for Energy Management: Advanced energy management system (EMS) implementation can improve grid stability, balance supply and demand, and maximize the utilization of stored energy [5].

Limitations on Efficiency

Material Innovations: Efficiency and cost-effectiveness advances may result from research into alternative materials such as dye-sensitized solar cells (DSSCs), organic photovoltaics (OPVs), and tandem solar cells [6].

Concentrated Solar Power (CSP): By directing sunlight onto high-efficiency PV cells or thermal storage systems, combining PV systems with CSP technology can increase overall efficiency [7].

Space Necessities

Urban Solutions: Installing solar panels on windows, facades, and other vertical surfaces can make the most of the restricted space in urban settings [8].

Agrivoltaics: This technology, which combines solar panels with agricultural land, enables dual land use by producing crops and energy [9].

Environmental Impact

Lifecycle Assessment: From raw material extraction to end-of-life disposal, conducting thorough lifecycle assessments (LCA) of PV systems can pinpoint areas for environmental performance improvement [5].

Sustainable Practices: The environmental impact of PV systems can be reduced by encouraging manufacturers to implement sustainable practices, such as using more recyclable components and fewer hazardous materials [4].

Grid Integration

Demand Response: By putting demand response plans into place, energy usage may be synchronized with times when solar power is at its peak, which will ease grid strain and improve system dependability [1].

Micro grids: Especially in isolated or underserved locations, creating micro grids with PV systems might improve energy resilience. During blackouts or emergencies, micro grids can function independently of the main grid [9,10].

Photovoltaic (PV) and solar systems present many challenges, but they also present enormous opportunities for sustainable energy and a more environmentally friendly future. Solar energy solutions can reach their full potential if all of these issues highlighted are resolved by technological innovation, supportive legislation, and strategic planning. We may gradually move toward a cleaner, more resilient energy system that benefits society and the environment by overcoming these challenges.
