Global Horizontal Irradiance solar (GHI) solar holds immense promise for its efficiency and adaptability. However, the widespread adoption of GHI solar systems has been impeded by the challenge of affordability. In this article, we embark on a journey to explore innovative strategies and solutions aimed at making GHI solar more accessible and cost-effective. From technological advancements to policy incentives, each facet contributes to a brighter, more sustainable future powered by the sun’s abundant energy.

1.Economies of Scale:

Expanding the scale of GHI solar projects can significantly reduce costs. Larger installations benefit from economies of scale, as the cost per unit of energy generated decreases as the size of the project increases. Encouraging utility-scale GHI solar installations can, therefore, make this technology more affordable.

 2.Financing Options:

Solar leases and power purchase agreements (PPAs), for example, can increase the accessibility of GHI solar to a broader range of users. Individuals and businesses can use these ways to create solar systems with little or no upfront investment and pay for the electricity they generate over time.This approach spreads the financial burden and makes GHI solar a viable option for more people.

3.Research and Development:

Investing in research and development focused on GHI solar technologies can lead to breakthroughs that significantly reduce costs. This may involve innovations in materials, energy storage, or tracking systems that improve the efficiency and reliability of GHI solar installations.

4.Training and Education:

Skilled labour is crucial for the installation and maintenance of GHI solar systems. Training programs and educational initiatives can help develop a qualified workforce, reducing labour costs and ensuring the long-term viability of GHI solar installations.

5.Regulatory Streamlining:

Streamlining the regulatory process for GHI solar projects can cut down on permitting and administrative costs. Simplifying approvals and reducing bureaucratic hurdles can make GHI solar more attractive to investors and project developers.

6.Local Manufacturing and Supply Chains: 

Encouraging local manufacturing of solar components and fostering regional supply chains can contribute to cost reduction. When solar components are produced and sourced locally, transportation costs and import tariffs are minimised. This can lead to a more competitive market for solar equipment and, ultimately, lower prices for GHI solar installations. Governments and businesses can collaborate to support domestic solar manufacturing initiatives, thereby creating jobs and reducing the reliance on international markets, which can be subject to price fluctuations and supply chain disruptions. A robust local solar industry can drive affordability and resilience in the GHI solar sector, benefiting both the economy and the environment.
