Residential PV

Faced with raw material and labor shortages, solar manufacturers have stressed the need to find alternative supply chains and to push automation and internet of things applications on the factory floor to keep production running.

Bridge to India figures show dominance of Chinese inverters, which supplied almost 80% of installs from July last year to the end of June.

As of June 30, the country installed 90.5 GW of renewable energy capacity from solar (utility-scale and rooftop), wind and biomass resources. 

Solar curtailment might become a valuable aspect of future PV deployment, particularly if grid operators start focusing on ‘curtailment management’ instead of ‘curtailment prevention.’ Management would include measures such as flexible generation, storage, load flexibility, and regional coordination.

The state electric company has issued a call for expressions of interest in installing the residential arrays.

French researchers have developed a machine-learning model to clean low-power PV projects and standalone solar arrays in rural areas isolated from the grid.

The story of residential rooftop solar is one of liberation. Confronted with high module prices, early PV adopters experienced significantly longer payback periods – it was not unheard of for homeowners to be making monthly finance payments higher than their utility bills. But consumers were motivated, seeking independence from the stranglehold that electricity providers had on them with ever-increasing utility rates.

Australian scientists have identified seven methods to prevent PV losses when overvoltage-induced inverter disconnections occur. The methods include battery storage, reactive power inverters, export limits, distribution static synchronous compensators, the replacement of old conductors in power grids, load reconfiguration, and dynamic voltage restoration.

A new report by ICRA says large-scale solar in the country will likely achieve the 60 GW target set by the Indian government. Rooftop solar and wind, however, will see a shortfall.  

The projects are to be carried out on a turnkey basis, with solar modules and inverters supplied by Rajasthan Electronics & Instruments Limited (REIL). Bidding closes on August 4.
