Residential PV

To accelerate the adoption of technological innovation and digitalization in the renewable energy sector, concerted efforts are needed from policymakers, industry leaders, and technologists alike. Governments can create supportive policy environments, invest in research and development by providing incentives, at the same time supporting early-stage companies by creating favorable regulatory environments to fostering public-private partnerships.

A group of researchers in Australia has outlined a new methodology to determine the minimum power rating of energy storage systems (ESSs) used for emergency under-frequency response. The ESS size must be calculated to maintain the frequency within the standard operating range.

The Chinese manufacturer’s new battery energy storage system consists of an inverter ranging in size from 5 kW to 13 kW and a storage system of 10 kWh to 30 kWh. Up to five units can be connected in parallel.

The grid needs to modernize to meet a booming demand for electricity, which is only predicted to grow even further in coming years. IEC Standards are key to help with the transition.

Large-scale solar + storage deployment is the main option left to avoid power shortages, as they can be deployed much faster than new thermal and hydro assets. Recent gigawatt-scale solar + storage auction results, with a record low price of INR 3.4/kWh, show that such deployment will be highly economical, says a new study from the University of California’s India Energy and Climate Center.

Waaree Renewable Technologies, the solar EPC arm of Waaree Group, has reported a revenue of INR 236.35 crore and net profit of INR 28.16 crore for the first quarter of FY 2024-25.

Researchers in Malaysia have proposed a new approach to identify the optimal power sizing ratio to balance PV energy capture with inverter costs. The calibrated model is said to accurately reflect the relationship between inverter efficiency and real-world system behavior.

The adoption of smart technologies is reshaping the utilities industry, with a particular focus on smart grids. Smart grids leverage advanced sensors, Internet of Things (IoT) devices, and real-time data analytics to transform how electricity is generated, distributed, and consumed.

In its latest monthly column for pv magazine, IEA-PVPS provides a comprehensive overview of the state-of-the-art practices, best practices, and recommendations for managing reactive power amidst the growing integration of distributed energy resources (DERs). The article describes the regulatory frameworks and practical applications, underscoring the essential role of reactive power management in maintaining a stable and efficient power grid.

Multiple factors affect lifespan of a residential battery energy storage system. We examine the life of batteries in Part 3 of our series.
