Solar Helps Some Of The World’s Poorest Households Save $734,000 In 12 Months

Pollinate Group - solar power for the poor

Financial Year 2019-20 was a big year in SolarQuotes’ support for the NGO Pollinate Group, which supports low-income households in India by helping them replace expensive kerosene lighting with solar powered alternatives. By sending $1 to Pollinate Group for each quote request on this site, we’ve been able to send $64,655 their way in 12 months. [Read more…]

South Australian Government Push Ahead With Ill-Conceived Inverter And Smart Meter Rules

South Australia new inverter and smart meter rules

The SA government wants to unilaterally pick technology winners, write inverter standards and architect new grid control schemes. God help us!

This seems to have snuck under the radar: last week, the consultation period for proposed new South Australian smart meter and inverter rules closed and as far as we can tell, even in the renewable energy specialist media it attracted no attention. [Read more…]

Confession: I Believed Solar PV Was Causing LV Network Over-Voltage Problems. I Was Wrong.

You’ve heard the one about how the growth of grid-connected solar power is causing voltage rise on low voltage (LV) networks?

I sure have. I’ve written plenty about the phenomenon, often with an eye to what networks are doing to try and counter the problem.

However, courtesy of an e-mail from Green Energy Markets’ Tristan Edis, I have learned to my surprise that the “blame solar power” narrative simply isn’t true. [Read more…]

Worried about how a renewable-powered world keeps the lights on when “the sun doesn’t shine and the wind doesn’t blow”? Interested in energy systems modelling? [Read more…]

ARENA Study: Network Upgrades Better Than Solar Curtailment

citi power powercor report - Future Grid For Distributed Energy

More solar power on the grid has its challenges. Lots of people (and governments) are claiming the challenges can be solved with batteries and inverter control. Those solutions have a part to play, but a new study suggests there is important work to be done upgrading local networks.

While electricity distributors emphasise the importance of seeing “behind the meter” to manage the impact of renewable energy on low voltage (LV) networks, a study published by ARENA suggests network upgrades are going to be more effective in the long term. [Read more…]

New Solar Carport Design Allows 72 Panels To Be Installed In One Day

solar carpark

Don’t you wish rooftop solar was this easy? 72 panels installed in a day.

This is cool: PVDynamics in South Australia has come up with a fast, low-labour way to put solar panel roofs on outdoor structures such as pergolas and car parks. [Read more…]

Community Batteries Benefit The Grid More Says Latest Research

Community batteries - benefits

There is a middle ground between home and utility-scale batteries: the community battery. New research shows community batteries bring more benefit than individually owned energy storage systems.

The ACT government reckons there’s a gap between the household battery and grid-scale batteries: community batteries, either owned by or at least serving the needs of collectives of households. [Read more…]

Solar Power Is Getting Cheaper, Faster Than Anyone Predicted

Ramez Naam on the cost of solar energy

Solar energy is getting cheaper faster than anyone predicted says Ramez Naam.

Utility-scale solar electricity is going to drive fossil fuels out of the power generation market, sooner rather than later, according to clean energy investor and advocate Ramez Naam. [Read more…]

Regional Victorian Councils Go Public With EV Charger Strategy

EV charger locations in Victoria

If you haven’t got a Tesla EV (red dots =. Tesla chargers) then your options to recharge across Victoria are limited.

Regional Victoria is awash with public EV charging stations if you happen to be a Tesla owner. An April report by the Central Victorian Greenhouse Alliance says if Tesla charging stations (only usable by cars of the same marque) are excluded from an assessment of that state’s charging infrastructure, EV drivers face coverage gaps away from the city.

National Geographic Gives You A Peek At Your Hometown’s Climate – In 2070

Your Climate, Changed

What will your local climate be like in 2070?

Okay, this is cool: National Geographic’s latest contribution to climate change education is to try and give people a way to understand what their home cities will be like 50 years from now, if climate change follows the RCP 8.5 scenario. [Read more…]
