We’ll miss you Bosch Solar
Yesterday was a really sad day for fans of top-of-the-range solar panels. German giant Bosch announced that it could no longer bear to haemorrhage any more cash from its solar division. So it is going to shut the whole shebang down ASAP. [Read more…]
Panel prices have dropped 80% in 4 years – can they get any cheaper?
If you want to buy some absolute junk you can currently buy bottom end, ultra cheap solar panels for $0.50 per Watt. But I wouldn’t recommend it. Unless you want to risk your roof turning into a giant barbecue.
Most solar panel factories have been losing money hand over fist for at least the last couple of years. Many of the largest companies have lost many hundreds of millions. This has led many observers to believe that solar panel manufacturers will have to start raising prices in order to survive. In fact there is evidence of this starting to happen with panel prices rising slightly in the first 2 months of 2013.

What warranty are you really getting?
One of the most important things you have to watch out for when buying solar is the warranties that are offered.

How do you choose a good solar inverter? It’s a really important question. If you choose a bad inverter, it may turn out to be noisy, inefficient and unreliable. If you have a look at the inverter reviews that are coming in to SQ, some inverters appear to have an awful failure rate. For example at the time of writing the Beijing Kinglong New Energy (KLNE) inverter reviews report 7 failures from 13 reviews! Ouch!
Here is my attempt to answer this important question. And I’ve provided a transcript of my rantings below the video. [Read more…]
Crunching the numbers on your solar panels’ performance is fun!
One from the mailbag today that is bound to please fellow solar nerds:
Nigel Morris and a Dog’s Breakfast
Nigel Morris of Solar Business Services has described current renewable industry regulations as being like a “dog’s breakfast”. And while his comments may not come as a surprise to many solar power insiders, the fact that he admitted feeling sympathy for utilities networks just might. [Read more…]
