Choice of Solar inverters: How to choose a good solar inverter? Solar inverters are the next big thing in Australia. In such a scenario, it is inevitable to be equipped with the best of facilities. Hence choosing a good solar inverter becomes a must. From previous reviews, it has been found out that the failure rate of the inverters is abruptly high. All the power in a solar system flows through the solar inverter. Any fault with the inverter will ultimately effect the functioning of the entire solar system. Therefore, the solar inverter becomes the most critical component of a good solar system. The efficiency of the solar system depends much on the working of the solar inverter. The solar inverter is the only component which is likely to fail early in a solar system. One cannot ignore the importance of a good solar inverter and should invest little extra….

The 10 dumb myths of solar installers #10 You can’t split arrays on different inclinations Yes it can be done. Sure there is a loss of output (in technical speech, a cosine loss leading to voltage mismatch dynamics because of different MPPs within the series strings) but this must be balanced against other benefits in, say, reduced installation cost and the ability to fit more panels on a roof. The CEC guidelines say a maximum of a 5% difference in inclination, yet most installers won’t even do that. In reality the guideline should be scrapped or increased to a higher figure more like 15%, as long as the consequences are understood and explained to the customer and the economics of a larger system outweigh any losses per capacity invested. Please bury these myths for everyone’s benefit By burying these myths, Australians will be able to buy a lot more solar panels,….

The 10 dumb myths of solar installers #9 Frames should be used to ensure panels are optimally tilted to the North No, this is old thinking. Adding the cost of 20 or 30 cents per watt to a system that costs $1.00 per watt so the the panels are ideally tilted to eek out every bit of output from a panel is a complete waste of money. With the exception of completely flat roofs where build-up of dirt and grime will be a real problem, flat racking is the go. If space permits, you could instead install 30% more panels for the same price as using tilt framing. Better to install more panels than frame – because that creates economies of scale and brings the cost of panels down in the future!
