Residential PV

The race is on to process applications for central payments across the world’s biggest solar market, particularly as qualifying projects must reportedly be grid connected this year. The final electricity price will be a major competitive factor considered by the Beijing authorities.

With clean energy being generated at lower and lower prices around the world, solar power is playing a leading role in bringing the curtain down on coal, and will help the decarbonization of transport and space heating too.

Rebates and zero-interest loans for solar panels, solar hot water systems and batteries account for one of the major spends in Victoria’s 2019/20 budget and come at a cost of $1.3 billion.

There’s nothing high tech about resistance heating in the form of an immersion hot water element. But when added to rooftop solar PV, it can be a powerful way to maximise self consumption – when coupled with a smart control system. 

The Institute for Energy Economics and Financial Analysis has estimated the effect on the payback period of PV systems when adding EVs and storage in Germany and Britain. In both cases, system owners are likely to reduce their payback period by significant margins as increased self-consumption can offset the incremental phase out of government incentives.

The Victorian Government has taken the decision to pay rebates, under its Solar Homes package, to some 600 otherwise eligible households who installed solar PV systems but failed to follow the program’s procedure. 

The first million took 40 years, the second million took two years and the third million will arrive two years from now.

The latest figures from the Australian Energy Market Operator (AEMO) show that solar continues to eat into the share once firmly held by coal on the back of a dramatic increase in installations over the past 12 months. The trend was backed by energy storage facilities which continued to gain foothold as providers of frequency control and ancillary services, lowering overall costs in the first quarter of 2019.

The Beijing authorities have confirmed the payment levels to be made according to type of project and region from July onwards but an auction process will be involved so the figures are for guidance only. No decision has yet been made on the 30 GW of capacity added since the end of May.

Due to a jump in medium (+15kW) to large (+100kW) rooftop solar installations, there has been a dramatic increase in grid scale solar generation. This has contributed to renewables supplying monthly 14-15% of total generation since last November, an increase from 10-11% share this time last year, new research from The Australia Institute finds.
