Restraint/Challenge

High Initial Capital Investment and Installation Costs

• Despite declining module prices, high upfront costs associated with rooftop solar PV installations remain a key barrier to widespread adoption, particularly for residential consumers and small-scale businesses. Expenses extend beyond panels to include inverters, batteries, mounting systems, and professional installation, making the initial investment substantial
  • For instance, homeowners in Europe and Asia have reported that installation costs can represent nearly half of the total system expenditure, limiting affordability even with available subsidies. As a result, adoption rates among middle-income households tend to lag behind commercial and industrial segments with stronger financial capacity
• Challenges also arise from the need for specialized labor, electrical upgrades, and compliance with grid-connection regulations, which contribute to extended project timelines and added costs. These technical requirements deter many potential users seeking rapid deployment and limited maintenance involvement
• The lack of uniform financing structures and limited awareness about long-term economic benefits further exacerbate consumer hesitation. Some end users remain cautious about payback expectations and potential changes in energy tariff regulations that could affect return on investment
• To overcome these limitations, key industry stakeholders are promoting leasing models, community solar projects, and pay-as-you-save schemes to reduce entry barriers. As costs continue to decline due to scale economies and innovation, addressing affordability through accessible financing and streamlined installation practices will be crucial for sustaining market growth in the rooftop solar PV sector
