Solar panels and solar panels income

Are high income households more motivated to install solar panels?

In contrast, households with high income may still be more likely to experience bill stress (and therefore be more motivated to install solar panels) if they have little accumulated wealth to cover large expenses which may exceed temporary income. Aggregation issues present another challenge for empirical analysis.

Does income affect solar-panel uptake?

As income increases, the marginal effects are positive and significant for category (2,1) and (3,1). The magnitudes are three and four percentage points respectively. These positive and significant coefficients suggest that higher income is associated with higher likelihood of solar-panel uptake, when focusing on the bottom quartile for assets.

Do higher incomes promote solar uptake?

Alternatively, higher incomes could promote solar uptake, which could instead suggest the possibility of a positive relationship. This is based on the fundamental notion that income is an economic resource which can allow households to afford the upfront cost of solar panels. There is also the possibility of a non-linear relationship.

Does income affect household solar-panel uptake in Australia?

Income has a non-linear impact on household solar-panel uptake in Australia. The impact of income is positive at low incomes but negative at high incomes. However, evidence of this non-linearity relates only to high-wealth households. Omitting wealth variables can inflate apparent income impacts.
