Rooftop PV

Researchers in the U.S. have demonstrated, using simulations, PV system generation can range from 18-60% of clear-sky potential during hurricanes – provided the arrays do not suffer damage. According to them, solar installations could continue to provide back-up power when grids are down during hurricanes, especially if coupled with energy storage.

Module price falls driven by the energy demand slump and Chinese oversupply may reverse at the end of the year, Germany appears immune to the Covid rooftop curse and emergency funding has been offered up to EU businesses affected by the crisis.

The government is considering a €0.12/kWh feed-in tariff for PV installations with a generation capacity of up to 5 kW and of €0.10 for 5-30 kW systems. If implemented, the scheme will come into force next month.

Coronavirus-related disruption severely impacted solar installation during the first three months of the year, as the nation added only 689 MW of utility scale PV, against the 1,864 MW that was scheduled to be commissioned.

Australia’s rooftop PV fleet continues to grow in the face of uncertainty surrounding the outbreak of the pandemic, posting another big month above 200 MW. Mega-household solar systems are growing in popularity, but retailers and installers can see the storm clouds gathering.

U.K. business Roof Tiles Technology Ltd has developed a solar tile with a claimed efficiency of 17.5% and power output of 175 W per square meter. The company’s founder, Antonio Lanzoni, said a PV system featuring the product would cost 25-30% more than a standard solar rooftop.

Minister of economic affairs and climate change, Eric Wiebes, has written to parliament to confirm grid companies do not have to pay PV system owners when their installations are disconnected from the network due to capacity issues or poor-quality voltage.

The incentive scheme awards a 23-year, $0.12/kWh feed-in tariff to rooftop arrays with a generation capacity of up to 200 kW. Already, 141 municipalities have applied to install 116 MW of rooftop solar capacity and the government has increased the program’s budget from $28.5 million to $143 million.

The figure took the nation to a cumulative 120 MW at the end of the year, according to figures published by Norwegian solar industry organization the Solenergiklyngen. Around 2 MW of the capacity added in 2019 came in the form of off-grid projects.

According to the Czech Solar Association, the move against solar will likely trigger defaults for thousands of PV projects. The Czech government also plans to build more nuclear power plants and has vowed to extend the lifespan of its coal-fired plants.
