ARENA backs cloud tracking project to boost solar output

An Australian-made cloud tracking system that predicts cloud movements to help get the most out of solar panels, is being backed by the Australian Renewable Energy Agency (ARENA).

ARENA announced on Thursday it would give $442,000 in funding to Fulcrum3D to further develop its advanced cloud tracking system.

cloudcamARENA CEO Ivor Frischknecht said that the $904,000 project was part of a suite of ARENA funded projects to improve the reliability and increase the use of solar PV in Australia.

“Effectively predicting off-grid solar PV output means diesel generators can be switched on before production drops or solar output can be gradually ramped down, smoothing energy delivery and potentially allowing more solar to be used.

“Cloud tracking also has potential on-grid applications. At higher solar penetration levels accurately predicting energy generation is important for system stability, on or off-grid.

“Fulcrum3D’s ‘CloudCAM’ forecasting technology takes a clever approach to cloud tracking”, Frischknecht said.

The ARENA funding will help get home-grown technology from the development stage to pilot scale demonstration.

It will be developed and trialled at the 1 MW Uterne solar PV plant in Alice Springs, which is currently being expanded with 3.1 MW of additional solar.

“The project will trial ground-based sensors that can better identify cloud height and track clouds that are layered at different altitudes and moving at different speeds,” said Frischknecht.

“This is a step forward from current forecasting technologies that do not cope well with multi-layered cloud bands.

“The approach marries fit-for-purpose camera hardware with specialised software to predict changes in PV energy output using cloud characteristics and velocities.”

The project is scheduled for completion in September 2015.

    Any technology that allows network operators the ability to deal with fluctuations in solar generation proactively instead of reactively would greatly increase grid stability.

    One more tool in the toolkit of technologies needed to increase the penetration of intermittent generation technologies.

    Yes, and it’s not too much of a stretch to envisage fully automatic control of switching in/out of solar assets with fully computerised oversight.
