Solar Inverter Efficiency: What you need to know before buying.

January 28, 2012 2025-07-29T09:39:58 by 1 Comment

Everything goes through the inverter so its efficiency is critical.Solar inverter efficiency is a critical specification that directly affects the efficiency of your entire solar system. It is almost always a much more important consideration than solar panel efficiency.

All the power generated by your solar panels has to go through your inverter before you can either use the power in your home or export it to the grid (and get paid) so every percent of extra efficiency that you can squeeze out of your inverter will directly improve the performance and payback of your solar system.

So do you just need to pick the inverter with the highest “efficiency” number on the specification sheet? Well I’m afraid it isn’t quite that simple. (You guessed I was gonna say that didn’t you?!) [Read more…]

How Much Does Off Grid Solar Cost?

January 12, 2012 2017-06-28T11:29:28 by 81 Comments

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?

January 10, 2012 2016-05-30T14:06:40 by 15 Comments

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.

Will your solar power system protect you from power cuts?

I get asked this question a lot.

Unfortunately the short answer is: No – A standard grid connect solar system will not protect you from blackouts.

Kind of counter intuitive isn’t it? You go to the trouble and expense of your own little solar power station, and then you have no power if the electricity grid goes down. [Read more…]

The Problems With Thin Film Solar Panels

December 29, 2011 2024-10-03T09:31:56 by 26 Comments

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!”.

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
