What happens when your inverter gets old?

Ok, so if solar panels are supposed to last 25 to 30 years, how many years can you expect your solar inverter to last?

A very good question, with no clear-cut answer, I'm afraid.

Consider Corrosion

Corrosion issues should be considered for solar panels and framing systems on roofs, as it is a harsh environment up there, AND the general expectation is that these things should last for 25 years, at least! In this context, corrosion is a real issue over time.

Some common sayings we all hear: "Dissimilar metals corrode!" and "Only use stainless-steel with aluminium, as they don't corrode". Well, they are only 'sound-bites', and there is a LOT more to it. Suffice to say, a well-designed system with selected materials will give the longest life.

Dangers of Coal

We all hear things like: "There are a lot of harmful emissions from fossil-fuel generators like coal", and perhaps there is mention of "CO2" and "climate-change" or even "global warming", and we assume its all the one thing - well, its not.

Coal is called "dirty coal" for very good reasons - namely, health reasons.

Electricity and Gas GOING UP!

Here is what I thought a good summary of how the energy market in Australia has got itself in a *real knot*, due to decisions made within/by/for the Australian energy market itself!

Unfortunately, the losers include all of us - prices of electricity and gas will rise. There is some saving grace in the measure of price stability that big wind and solar generation will give us, ie prices could be more volatile without them.

Electricity and gas prices: why you're paying more

SA Leads the way for *Low Energy*

This article highlights a few things: How low SA power usage has gone; How low it is forecast to go by the national Australian Energy Market Operator (AEMO); How SA is a now a world leader(!) in the ratio of Renewable Energy to non-renewable energy usage; AND the speed with which the *change* of this ratio is occurring.

The AEMO are the folk who are charged with running the *artificial* energy market system Australia - and they seem to be in a difficult spot at present with solar, wind and energy efficient plant and appliances, all *severely* reducing, in a very quick way, the nice forecasts of rising power demand they made for the coal and gas people.

Renewable target cuts would deliver billions to gentailers as power prices soar

Scrapping or winding back Australia’s Renewable Energy Target would lead to significant increases in electricity prices, while delivering a windfall profit to power companies of as much as $70 billion, according to new analysis from Bloomberg New Energy Finance.

FREE solar!

I was cold-called the other day to see if I was interested in having solar installed for *FREE*!

Now, being in the solar game for 14 years, and never having encountered a true 'free lunch' yet, I thought I would just ask a few questions and get some idea of how this offer would work. It seems that, yes, the solar truly is installed for *FREE*!, but you then pay for the 'solar electricity you use' at a reduced rate.

The advent of Micro Inverters - Scourge or Saviour?

Any new technology comes about for good reasons - folk won't buy if it does not deliver.

The question of concern here is - will it deliver for our market, and the signs we've seen so far give us doubts. Now that's not to say that these doubts can't be cleared up, its just that we are not getting the answers we would have thought.
