For example, Germany’s FIT policy spurred significant growth in solar energy capacity by ensuring a predictable return on investment. The implementation of FITs encourages both large-scale solar farms and smaller distributed generation projects, fostering a diverse and resilient energy sector.

• Renewable Portfolio Standards (RPS)

  RPS mandate that a certain percentage of electricity sold by utilities must come from renewable sources. States with RPS, such as California, have witnessed substantial increases in solar energy capacity as utilities seek to comply with the regulations. This policy mechanism creates a consistent demand for renewable energy, driving innovation and cost reductions.

• Tax Incentives and Rebates

  Tax credits and rebates reduce the upfront costs of solar installations, making them more affordable for homeowners and businesses. The federal Investment Tax Credit (ITC) in the United States has been instrumental in promoting solar energy adoption by lowering the initial capital expenditure. These incentives stimulate demand and accelerate the deployment of solar technologies across various sectors.

• Net Metering Policies

  Net metering allows solar energy system owners to receive credit on their electricity bills for excess energy they send back to the grid. This incentivizes self-consumption of solar energy and promotes distributed generation. States with strong net metering policies, such as Massachusetts, have seen significant growth in rooftop solar installations, empowering individuals to generate their own clean energy.
