Growth Drivers

• Emerging need for energy independence: The need for energy independence is gaining demand thus solar generators are being greatly preferred by individuals, businesses, and communities to reduce dependence on grid electricity and increase self-sufficiency. The trend of growing demand for solar generators draws focus from concerns such as grid reliability, energy security, and sustainability, besides cost-saving and autonomy. Solar generators allow individuals and the community at large to take responsibility for generating cleaner energy, reducing their carbon emissions, and mitigating risks related to price volatility. As a result, solar generators are increasingly adopted as they render backup power to people in grid outages and natural disasters, ensuring continuity of energy supply and supporting emergency preparedness.
• Technology innovations: The solar generator market is being powerfully driven by technological innovations. The continuous development in improving solar panel efficiency, energy storage, and smart grid technologies yields benefits in improved performance, better cost-effectiveness, and wider accessibility of solar generators. The better integration of solar generators into the existing energy infrastructure has been made even easier with the incorporation of such smart grid technologies as grid-tie inverters and monitoring systems, thus making them increasingly deployable and resilient.
  
  Furthermore, all these technological advancements have contributed to increased solar generator market growth and thus have made solar generators an increasingly viable and attractive option for renewable energy generation. For instance, according to ArcVera Renewables, bifacial designs allow to capture of sunlight from both sides of the panel increasing the solar generation capacity up to 25%.
• Advancement in energy storage: Energy storage advancements have been crucial in increasing the viability and acceptance of solar generators to store excess energy supply generated at times of high production. Improvements in the development of lithium-ion batteries by increasing capacity and durability are cost-effective, thereby being instrumental in driving recent solar generator market growth. For instance, Tesla Powerwall is a fully integrated AC battery system for residential or light commercial use. It comes with a rechargeable lithium-ion battery pack that provides energy storage for solar self-consumption, time-based control, and backup.
  
  These advancements have addressed the concerns of energy storage, the reliability of solar generators, and being a consistent source of renewable energy during periods of low sunlight or high energy demand. Thus, making energy storage an integral and inseparable function in solar generator systems, further pushing the use of sustainable energy solutions.

Challenges

• Intermittent energy supply: The intermittency of energy supply by solar generators, heavily depends on weather, season, and time of day. For example, a generator can function at its highest capacity of 100% or even more on a sunny day but on a cloudy day, it might produce only 20-30%. The change in weather patterns can bring about energy deficiencies making solar generators inadequate in supplying sufficient energy for baseload needs. This intermittency shows the growing need for advanced energy storage systems, grid management technologies, and hybrid power solutions to curb the variability in solar energy generation.
• Comparison with traditional energy sources: Solar generators are in intense competition with conventional sources of energy, such as fossil fuels, that have built infrastructure, achieved economies of scale, and captured a larger solar generator market share. For instance, natural gas, the most preferred energy mix is characterized by relatively low electricity generation costs an average of 6-8 cents per kWh compared to the average cost of solar energy generation at 10-15 cents per kWh. Moreover, conventionally derived resources are assisted by government subsidies, tax concessions, and other supportive regulations unlike solar generators, which strengthen their market dominance thus, making traditional sources more reliable.
