How Policy Can Shape Future Solar Energy Expansion

The solar photovoltaic (PV) market is experiencing rapid growth. In 2021, the sector was valued at $160.3 billion globally, with forecasts predicting a compound annual growth rate (CAGR) of 15.7% between 2020 and 2030, leading to a projected market value of $607.8 billion by the end of the decade.

Government policies significantly influence this growth by affecting the affordability and accessibility of solar power systems for both homeowners and businesses. In the United States, federal tax credits make new solar installations more affordable, while the European Union is developing a comprehensive strategy to expand solar energy capacity to meet energy needs.

These government plans and policies are pivotal for the future of solar energy. Beyond general efforts to increase solar adoption, authorities can implement practical measures such as mandating clean energy for new buildings and simplifying the permitting process for solar panel installations.

Here is an in-depth look at solar-positive government policies and how they help increase the accessibility of PV systems.

Loosening Rules on Tax Credits for Renewable Energy Investments

Adjusting current regulations is one way to make solar more accessible. For example, in 2023, the European Union made efforts to ease restrictions on tax credits, simplifying the process for member states to provide them for solar installations. This led to changes such as France's clean energy tax credit. The EU is also working to create incentives and change permitting processes to retain clean energy companies, many of which have moved operations to the U.S., where incentives and solar-friendly laws are already in place.

Investors have several options for putting capital into renewable energy:

• ​Commercial or residential solar PV systems: Direct investment in these projects supports renewable energy and reduces reliance on the grid.
• ​Real estate investment trusts (REITs): Purchase shares in eco-friendly properties with clean energy features.
• ​Green bonds: Similar to traditional bonds, but funds are used for clean energy projects or environmentally-friendly developments.

Relaxed permitting rules and incentives for both companies and homeowners make solar power an attractive sustainability-related investment.

Streamlining the Permitting Process for Solar Farms

The EU has faced challenges with complex administrative processes and permitting rules, which conflict with clean energy goals. The EU Commission has plans to streamline the permitting process for renewable energy projects and cap the wait time for permits on large-scale projects. These changes aim to reduce administrative delays and foster a more positive outlook for renewable energy.

New technology, such as solar design software, is also making it easier for investors and homeowners to maximize the yield of their solar power installations. Permitting and large-scale design tools benefit commercial and utility-scale solar projects, while technology and incentives are also available for small-scale solar.

Offering Tax Credits for Small-Scale PV Systems

New laws in the EU are making solar more accessible for residential users. For example, Germany has introduced tax exemptions for small-scale residential and commercial PV systems, combined with new tax credits to make installations more affordable. These changes are designed to increase the accessibility of rooftop solar and mirror U.S. incentives, which currently offset 30% of a project's cost.

Mandating Rooftop Solar for New Construction Buildings

The EU is taking further action by mandating the use of clean energy in new buildings. Commercial and public-use buildings must install rooftop solar panels by 2026, with larger public buildings required to add panels by 2027. By 2029, new residential constructions will also need to have solar panels. Technology, such as software for roof-mounted solar arrays, helps optimize panel placement and output, which is especially important for rooftop installations.

Freeing Up Land for Utility-Scale Solar Development

Land availability is a significant challenge for utility-scale solar development. A one-megawatt (MW) solar array can require up to 10 acres of land. Authorities are working to free up land to support the expansion of utility-scale solar. In the U.S., the Bureau of Land Management (BLM) has developed a long-term roadmap for using public lands for utility-scale solar, including both solar arrays and battery storage facilities.

These developments are crucial, as the U.S. aims to generate 30% of its electricity from solar by 2030. Globally, the use of utility-scale solar could triple by the end of the decade, necessitating careful land use and management of conflicts between solar farms and agricultural businesses.

Providing Training Programs for Renewable Energy Careers

The expansion of solar power also requires a skilled workforce. Europe will need one million solar workers by 2025, but there is currently a shortage of trained professionals. The European Institute of Innovation and Technology (EIT) has launched programs to upskill and reskill energy workers, providing pathways for new workers to enter the field.

How Can Your Business Contribute to the Future of Solar Energy?

Businesses can invest in solar energy to gain multiple benefits, including reducing their carbon footprint, qualifying for tax credits and subsidies, and lowering operating expenses by generating their own energy. Solar technology software can help businesses maximize solar output and minimize energy purchases from the grid. By investing in solar, businesses become part of the transition to clean energy.

Conclusion

The future of solar energy is bright. While challenges such as administrative processes remain, policy-driven initiatives are expected to continue shaping the renewable energy landscape. By streamlining permitting processes, offering financial incentives, and mandating sustainable practices, governments are catalyzing the growth of the solar market and paving the way for a more sustainable and energy-secure future.
