Solar power generation can be divided into two technological schemes: photovoltaic (PV) and concentrating solar power (CSP). The principle of CSP generation is to utilize large-scale mirrors to collect solar thermal energy, heat it through a heat exchanger to produce water steam, and then supply it to traditional turbine generators for electricity generation .

Impacts over the life of PV systems are quantified using life cycle assessment (LCA) methods and can be used to estimate energy and carbon payback times. Energy payback time (EPBT) is the time required for a PV system to generate the same amount of energy used during system manufacturing, operation, and disposal.
Energy payback time (EPT) is the time required for a generation technology to generate the amount of energy that was required to build, fuel, maintain and decommission it. The EPT is closely linked to the energy payback ratio and depends on assumptions made on the lifetime of a technology [59,70–73].
The solar payback period is the length of time it takes for solar panels to pay for themselves. While the initial investment in a solar PV system may seem expensive, one of the main benefits of solar panels is that they require very little maintenance.
Energy payback time (EPT) is the time required for a generation technology to generate the amount of energy that was required to build, fuel, maintain and decommission it. The EPT is closely linked to the energy payback ratio and depends on assumptions made on the lifetime of a technology [59,70–73].

The payback period for rooftop solar could fall by 31%, from 12.6 years in 2022 to 8.7 years in 2030. Heat pumps have the shortest payback periods under the “average power price” scenario. The payback period could decrease by 28% in this time frame, from 12.5 years in 2022 to nine years in 2030.
A great way of shortening the solar payback period is to sell excess electricity generated by solar PV panels back to the grid. Your energy supplier will pay you for electricity that you supply back to the grid by means of the Clean Export Guarantee under the Micro Generation Support Scheme.
