Researchers at the University of Sydney have made a significant leap forward in solar cell technology by achieving the highest efficiency reported to date for a perovskite-CIGS tandem solar cell built on a flexible steel substrate. This innovative design boasts a record-breaking 18.1% power conversion efficiency, paving the way for a new generation of adaptable and highly efficient solar panels.

Factors to consider when choosing your solar system

So you want to go solar and save your hard earned money by generating your own power instead of making a quarterly donation it to the power companies, who only ever seem to raise power prices.

A key reason that someone would get rooftop solar is because they would dearly love to never pay another power bill again. The problem is it is not immediately obvious which PV system will eliminate your bill as it depends on a number of factors.   If you are unfamiliar with solar it is difficult to know what questions to ask a solar retailer and how to distinguish valid claims from invalid claims. So how do know what your annual power bill is likely to be for a given solar system?  Here is a broad overview of how to work that out:

A Chinese Government controlled company has slashed by half the solar power capacity Canberrans can have on their roofs, blindsiding MPs who fell asleep on their watch.

While the ACT Environment Minister Mick Gentleman, Climate Change Minister Shane Rattenbury and their parliamentary colleagues were looking the other way, power distributor Evoenergy unilaterally declared that the territory’s residents would be forced to rely on fossil-fuelled power indefinitely.

Good news if you are a fan of Tesla, their Q2 2019 sales numbers absolutely crushed sales forecasts by the many Wall St 'gurus' with an irrational dislike of Tesla (perhaps it is because they have lost so much money shorting Tesla stock) with a record 95,200 cars sold (the Wall St 'gurus' predicted around 86,000 sales).

Most people think of a solar system as a way to save energy (at least energy drawn from the grid) and save money (which it certainly does). But few people think of their solar system as a revenue generating asset that will give you a higher rate of return than a high interest bank account.

Solar panels that are installed at an angle (in line with a pitched roof or on tilt frames) are generally self cleaning. However in dry, dusty areas or where panels are installed flat; dirt dust, grime and other substances such as bird droppings can build-up reducing the power output of the PV panels. Due to the nature of solar panels grime and bird droppings doesn’t need to cover an entire panel to reduce output significantly.
