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.

The move, if it goes ahead, will mean Tokelau becomes the first country to source 100 percent of its energy from renewables with around 93 percent of the its energy being sourced from solar and 7 percent from locally grown oil. The tiny Pacific microstate, situated halfway between Hawa’ii and New Zealand — from which it is administered — used its platform at the Durban talks to mischievously call on the rest of the world to follow its lead.

Skilfully using his moment in the sun (ahem), leader Foua Toloa told a meeting on the fringes of the UN climate conference that “By September next year, we will become the first nation using 100%-renewable energy, and number one in percentage greenhouse gas reduction in the Pacific and elsewhere.”

The country has decided to become a world leader in terms of percent of its use of solar energy to set the example to reduce carbon emissions. Tokelau is one of the Pacific islands which will be most affected by any changes in sea levels brought about by global warming.

All great I hear you say, but there is one fly in the ointment (or cloud on the horizon) — funding for the venture is not fully secured. According to The Guardian report, the tiny state must find $900,000 of the share of the $7.5 million project, money the microstate was hoping to obtain  from the Green Climate Fund. The fund was agreed to by countries in last year’s Copenhagen talks however while launched officially at Durban, matters such as how to unlock finance from the fund as well as finding sources, have yet to be determined.

But good luck Tokelau…the world’s leader in the use of renewable energy as a percentage of its energy (if all goes well). Whether this will be the template for other Pacific nations who are also threatened with climate change, remains to be seen. If it eventuates, Tokelau will expect to save 12,000 tonnes of CO2 during the operational life span of the 1MW solar power plant,according to The Guardian.

Toloa is obviously proud of his country’s world leadership in renewables. “No more noisy generators will disturb the quiet of the islands. We will be an example to the world, even though we have done nothing to deserve this,” he said.

Don’t Make these 10 Mistakes When Buying a Solar Power System

1. Buying the cheapest – because it is the cheapest.

If a solar system seems too cheap to be true, then it is probably is!

Here are 4 ways they get the price so low:

a) The solar company is buying absolute junk panels and inverters on the spot market in China

ACT Charges out of the Solar Sheds With Large-scale FIT

Interesting announcement this week that the ACT Government has passed legislation that clears the way for the introduction of the country’s first large-scale feed-in tariff (FIT). The solar bonus schemes have received a great deal of negative coverage in the last year or so as various state governments have backed away from their versions faster than cats at bath time (or is that being a little unkind to cats?).

Various state governments have pleaded financial difficulties as the reason for their winding back of what have been proven to be very popular schemes with the public. However the major point of interest of the ACT’s version of the feed-in tariff is that it will also be made available to large scale solar projects.

ACT environment and sustainability minister Simon Corbell told reporters following the passage of the bill that the legislation would set the Territory on course to its intended carbon neutrality by 2060 and would provide up to 14 percent of the ACT’s minimum electricity demand.

Hard-nosed readers, accustomed to government policy flip flops, both state and federal, may be asking two questions: Does the ACT initiative have national implications? And will the large-scale nature of the legislation mean more solar investment in the ACT?

Firstly to national implications. While one cannot see the state governments returning to state-based FIT’s so soon after gleefully ditching, or winding back, their own programs, the emphasis on covering large-scale solar projects may well play a part as states look to attract large investments. This may well be the kick up the … type of incentive that will also attract fans in the national Parliament just down the road.

Indeed the political makeup of the ACT does have a familiar ring to it. Cheered on by the Greens, who support the Labor Government in a loose coalition (see what I mean), and with the usual harrumphing from the Opposition Liberal benches who described the legislation as “costly and ineffective”, the ACT Parliament could well be a scale model of its larger, federal cousin.

Early indications on the second question of whether or not the legislation will attract large-scale investment to the ACT are more positive. Minister Corbell announced the arrival of at least two major commercial solar projects and was effusive in his praise for the bill.

“The passage of this important bill through the Legislative Assembly allows the Labor government to move ahead with its vision to make Canberra Australia’s solar capital and start to make the shift from non-renewable energies to clean alternatives,” he said.

John Grimes, chief executive of the Australian Solar Energy Society, has also backed the legislation describing it as an “innovative way of driving investment in big solar”.

So will the ACT be the “ideas person” behind the next stage of solar development in Australia?
Obviously this is early stages and the benefits may not be seen for some time, as well as the important question of whether or not costs for the scheme blow out.

So do you think it’s a good start?

AuSES-sponsored Conference Spins the Big Solar Wheel

Two of the key issues covered this week at the Solar 2011 conference have been (1) the growing affordability of solar systems for both domestic and commercial outlooks as prices plummet, and (2) the growth of international large-scale solar projects. The first has been made possible by the growth of the Chinese solar energy sector and has made cheap solar panels available to Australian households and businesses.

However are we likely to see massive scale projects backed by the federal government in this country? Well yes if the event organisers have their way. [Read more...]
