Government policies and incentives
Governments around the world have implemented supportive policies and financial incentives to promote the adoption of solar energy. These include tax credits, subsidies, grants, feed-in tariffs, and net metering programs, which make solar investments more attractive for individuals, businesses, and utilities. For instance, the Indian government has initiated multiple subsidies which are consistent with India's Intended Nationally Determined Contributions aim of achieving about 40% cumulative electric power installed capacity from non-fossil fuel-based energy resources by 2030. Thereby, driving the market growth over the forecast period.
Concerns related to cost and grid integration
While energy storage technologies continue to advance, the costs of establishing large-scale energy storage systems can remain quite expensive, limiting the overall economic sustainability of solar energy systems. Furthermore, integrating solar energy into existing energy networks can be technically challenging, necessitating infrastructure changes to handle two-way energy flows and assure system stability. Thus, this is expected to act as a major restraint for the market growth over the forecast period.
Expansion of product services by key players
The expansion of product services by key players is expected to offer an attractive opportunity for market growth during the forecast period. For instance, in January 2023, an Indian start-up, SOLAR-MAIT announced the offering of a 25-year warranty on its rooftop solar systems. with this offering, the company becomes country's first company to provide such a wide warranty and setting a new benchmark in the rooftop solar market. Simultaneously, SOLAR-MAIT has announced development ambitions and creative business models to build a system in India's rooftop solar sector. These initiatives include the formation of a company franchise in order to promote India's Aatmnirbhar Bharat Abhiyan (Self-reliant India campaign. Thereby, driving the revenue growth.
