Summary: This paper compares the economic sustainability of net metering, net billing, and all energy buy/sell methods for industrial PV systems in Bangladesh. The results show that the net billing and all energy buy/sell schemes have higher plant capacity factors and lower levelized cost of energy. They also achieve higher net present value and profitability index in the large PV system.

Summary: Commercial grid-connected rooftop solar PV systems are widely used in Malaysia, with the recently announced Net Energy Metering (NEM) 3.0 allowing commercial buildings to connect up to 75% of their maximum demand to the grid. This results in cost savings and energy offset for owners over a 10-year period.

Summary: This work compares the Brazilian first distributed energy net-metering policy with the new system. It reviews international distributed energy regulation development and the impacts on distribution grids. Equations are used to compare energy billing for consumers under the old and new policies. Simulations show that an increase in power injection could overload transformers and cause overvoltage. The new Brazilian policy reduces revenue losses but poses a risk for misplaced investments in the distribution grid.

Summary: Transitioning towards low-carbon energy systems requires increasing residential Photovoltaic (PV) contribution through PV self-consumption, which can be supported by adopting PV self-consumption policies and incorporating batteries. However, it is crucial to assess and mitigate the technical impacts of PV policies on distribution networks. Implementing a two-stage planning framework that optimizes PV and battery sizes, and evaluates impacts on distribution networks through Monte-Carlo simulations, is essential for achieving sustainable energy goals.

Summary: The government of Saudi Arabia has recently adopted regulations allowing consumers to install grid-connected PV systems in different sectors. However, the current energy exchange tariff is not encouraging for installation. This study investigates the economic feasibility of installing PV systems from the consumer side, using RETscreen software to simulate different cases in five cities. The results show that installing grid-connected PV systems is feasible if the system is designed to meet the annual energy demand of the house or less, with a payback time of around 10 years and a LCOE of 0.095 SAR/kWh.

Summary: This study analyzes the grid parity of distributed photovoltaic generation in San Juan Argentina, showing that the levelized cost of DG-PV is higher than the tariff price for residential customers. In order to achieve grid parity, the government should implement incentive mechanisms like Net Billing. The impact of different incentive mechanisms on residential users and utilities are compared, with a focus on the profitability of PV systems and the importance of considering taxes and tariffs in implementing incentives.

Summary: Recently, residential photovoltaics (PVs) for self-consumption have been rapidly proliferating due to various support mechanisms. The net-metering scheme, a prevailing support mechanism, enhances the economic benefits of PV adopters but also suffers from disadvantages such as missing utility network revenue and the spread of cross-subsidies. This paper analyzes the cross-subsidy effect of residential PV proliferation in the Korean electricity market and suggests introducing a new network charge design and targeted deployment policies to reduce the cross-subsidy effect.

Summary: As the global population grows, the demand for food, energy, and water will increase significantly. However, limited land availability and competition for solar resources pose challenges to resource generation technologies. In the United States, both agriculture and solar energy production have adopted densification schemes to improve yields and energy output per unit of land. This research proposes an Agrivoltaic food and energy coproduction architecture that optimizes power generation while maintaining crop productivity by implementing ideal anti-tracking during critical growth periods. This technology offers a viable pathway for widespread solar implementation throughout the contiguous United States.
