Can you live off-grid if you have solar panels?

With enough solar panels and a solar battery, you can store solar power and live off-grid. However, there are benefits of remaining connected to a utility provider - also known as being "grid-tied." Even if you produce enough solar energy to be self-sufficient, you can make money back from your utility provider through Net Metering.

Will subsidy phase-out accelerate the diffusion rate of solar PV technology?

Some scholars argued that the subsidy phase-out would accelerate the diffusion rate of solar PV technology (Wang et al., 2021; Chen and Wang, 2022), while others expressed concerns about residents' complaints in response to the subsidy phase-out policy (Zander et al., 2019; Liu et al., 2023).

Does PV generation subsidy phase-out affect total electricity consumption?

The results of our study indicate that there is a larger rebound effect on total electricity consumption during the announcement of the PV generation subsidy phase-out. However, this effect gradually weakens over time as the policy is implemented.

How long do solar panels last?

Based on recent estimates of panel lifetime, we assume that a solar panel lasts 30 years on average. Using BNEF data up to 2020, through a whole-model data upgrade, we update realised capacity factors for onshore, offshore, and solar technologies to the most recent values.

Why are PV installations carried out after the subsidy phase-out?

The installations carried out right after the announcement of the subsidy phase-out are likely in part due to the backlog of the firms installing household PVs.
