Would the solar industry be better off without government support?

Sir Humphrey discusses the UK's Solar Feed In Tariff

Fascinating article this. The UK’s only Green MP, Caroline Lucas, takes to the pages of The Guardian to launch a broadside against the UK Government’s investment policy in relation to solar energy.

The UK Government this week lost an appeal in the High Court against a lower court’s ruling that its retrospective attempt to change the solar feed-in tariff rates imposed by the previous Labour Government was “legally flawed”. The Cameron Government had tried to reduce the rates before the agreed consultation period had expired.

Innovative solar energy project to aid off-grid rural communities in Africa

The British-based solar energy charity organisation SolarAid has teamed up with Cambridge-based solar technology company Eight19 to provide solar energy at affordable prices to poorer people in rural parts of Africa.

SolarAid are a charity group working in rural areas throughout eastern and southern Africa with a bunch of great ideas. According to their website they believe jobs and business opportunities for poorer people in the rural areas of Africa is important. [Read more…]

Your Solar Panel & Inverter Warranty And The Law: What You Need To Know

Person signing a solar system warranty

Your Solar Panel Warranty and Solar Inverter Warranty have tough new minimum standards by law. Changes to the Australian Consumer Law came into effect on 1 January 2012. These are good changes which help protect you as a solar consumer from toothless warranties when buying a solar system. [Read more…]

Construction on Mildura solar system begins but what can taxpayers expect?

The announcement last month from R&D company Silex Systems that construction on Australia’s largest solar power station at Mildura, VIC, has begun gladdens the heart. And the hip pocket nerve. After all Victorian and federal taxpayers are helping to fund this venture to the tune of around $120 million.

How Much Does Off Grid Solar Cost?

off grid solar system

I had a phone call from a mate today asking for advice on buying an off grid solar system for his new house in suburban Melbourne. He was pissed off about paying the daily grid connection charge when his solar system was easily going to produce more power than he used. A typical grid connection charge is about $1 per day.

So what is the extra cost of getting completely off the grid with your solar system in the city compared to a standard grid connect solar system?

AC Solar Panels (microinverters) : The #1 Solar Trend to watch for in 2012?

Will 2012 be the year of the AC Solar Panel?

Before answering that question I should probably explain exactly what an AC Solar Panel is…

An AC Solar Panel converts sunlight to AC electricity at the solar panel.


What is an AC Solar Panel?

The short answer is: An AC Solar Panel is a solar panel that takes sunlight in and spits AC (Alternating Current) electricity out. This compares to a “conventional” DC Solar Panel which takes sunlight in and spits DC (Direct Current) electricity out.

AC Electricity is the type of electricity you need to power the appliances in your home. DC panels need a Solar Inverter to convert the DC electricity to AC. The big advantage of AC panels is that there is no need for an inverter to do that conversion, so you have a really simple design, a simpler installation, and adding extra panels becomes almost plug and play.

The Problems With Thin Film Solar Panels

If you are looking to buy a solar power system and have done any kind of research on the web, then you have probably  come across lots of people  arguing over the pros and cons of Thin Film Solar Panels compared to the more common monocrystalline or polycrystalline solar panels. In a nutshell, there are 3 major types of solar panel technology on the market:

  • MonoCrystalline,
  • PolyCrystalline
  • Thin-Film

It seems a lot of people are firmly in either the “Crystalline” or “Thin-Film” camp. And when discussing which panel is best, they can easily lose their objectivity with arguments along the lines of “Thin Film is the only way to go” or “Mono Crystalline and Poly Crystalline are junk!”.

Tiny Tokelau Takes on the World With Solar PV Plunge

By Rich Bowden

One of the least reported, though possibly one of the most important, announcements to come out of the recent climate change gabfest in Durban earlier this month was the one from tiny Tokelau, with a population 1,500 (and three cars as reported by the Guardian). The Pacific state said it is planning to replace its aged diesel generators with a $US7.5 million solar PV system.

Tassie comes in from the cold

Vast solar arrays in the middle of our hot baking deserts or mainland cities awash with solar panels are generally considered the most efficient way to soak up the abundant sun for energy in our country. In terms of suitability for solar farms in this wide, brown land of ours, the mind definitely points to swelteringly hot parts of the mainland, rather than the cool, fresh, green island of Tasmania.

Not so according to a recent study by the American Chemical Society journal Environmental Science & Technology which says the cooler regions of the world are, contrary to general belief, an excellent area to generate massive amounts of solar energy. The report says that cool climates, particularly those at a higher altitude, have massive potential to generate solar-powered electricity.
