Residential PV

The first part of pv magazine’s review of 2019 considers Q1, when solar early adopter Italy offered an optimistic start to the year by fleshing out its plans for PV but uncertainty still clouded the world’s biggest solar market. The potential for household solar installations to rocket the world over – helped by ever cheaper panels – prompted strategic decisions in the inverter market and analyst expectations were confounded as the cobalt and lithium price plummeted, bringing the EV revolution a big step nearer.

CNBC has uncovered a recently granted building permit that allows Tesla to put up “two canopy covers” over its new “solar test houses.” Earlier this year, Tesla CEO Elon Musk announced that 2019 was “the year of the solar roof.”

The government claims 292 MW more solar was installed than in the same period of 2018. Taipei reported solar power generation increased 51.7% year-on-year for January-to-October.

As solar and wind power enter the post-subsidy era, the next few years will be critical for China’s energy transition with investors learning to navigate the uncertainties of market reforms. With the 14th five-year plan – touted as a watershed in China’s energy system development – in the works, a report has recommended clear targets for 2021-2025 in terms of solar and wind power deployment and a reduction of coal consumption.

Almost all of the energy supplied in the Buddhist kingdom of Bhutan comes from 1.67 GW of hydropower capacity but with a rising population and energy demand, and an expanding economy, the 12 GW of solar the International Renewable Energy Agency estimates the Himalayan nation could host might reduce the risk of climate change-related blackouts.

The Italia Solare Forum event held in Rome laid bare the difficulty of securing permits for large scale projects at national and regional levels. Fast-tracking the process for big solar parks appears necessary to get Italian PV back on track.

The U.S. residential solar market – and 15 states – are at record highs according to analyst WoodMac’s ‘don’t call it a comeback’ Q3 report, driven by new market forces. The research firm held its 2019 U.S. solar forecast at 13 GW.

The China Photovoltaic Industry Association secretary-general has revealed the world’s biggest solar market is unlikely to add more than 30 GW of solar generation capacity this year after just 17.5 GW was installed to the end of October.

Japanese utility Kansai Electric Power has extended a demonstration project with Australian P2P energy pioneer Power Ledger to track renewable energy certificates and trade PV-generated electricity.

An international research team has developed a new approach for solar power forecasting that combines neural networks and pattern sequences for the first time. The performance of the new Pattern Sequence Neural Network (PSNN) was tested on an Australian data set that includes information from two years of forecasts. It can be used with different clustering and cluster-sequence extraction algorithms, and can be applied to multiple related time sequences
