Residential PV

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.

Dipal C Barua started installing rooftop solar systems in Bangladesh when the PV industry itself was in its infancy, with his company Grameen Shakti. Now heading up the Bright Green Energy Foundation, Barua installs small residential systems, streetlights, and irrigation pumps throughout rural Bangladesh under various government programs.

Dutch researchers have shown that power peaks caused by solar generation may be stronger under partial cloudiness than clear skies. According to their findings, mixed-cloud conditions can enhance PV power production due to light reflected off clouds, as well as their intermittent shadows on arrays, which reduce module temperatures.
