A STUDY conducted by researchers from Ateneo de Manila University has identified high initial costs and limited public awareness as major obstacles to the widespread adoption of rooftop solar power in the Philippines.

The study, led by Economics Professor Rosalina Palanca-Tan and published in Challenges in Sustainability, surveyed 403 households in Metro Manila and neighboring provinces to uncover the reasons behind the hesitance to invest in solar energy, despite its long-term benefits.

Although most respondents acknowledged the potential for solar energy to offer savings and contribute to environmental protection, the average installation cost of over $1,700 (or P100,000) proved prohibitive for many, especially those on minimum wage.

The study also highlighted that trust in providers, warranties, and perceived quality of installation often influenced decisions more than the upfront cost.

Despite 82% of respondents expressing interest in solar panels, only 20% had concrete plans to install them, with concerns about the lack of information on benefits and reliable installation services standing in the way.

The researchers recommend that government actions, including improved net metering rates, accessible financing options, and enhanced provider accreditation, could help overcome these barriers and boost solar adoption.

Additionally, word-of-mouth recommendations and community-based success stories were found to be effective in encouraging solar energy installations.

The study concludes that a combination of public education and targeted policy support is vital to unlocking the full potential of solar energy in the Philippines.
