My best solar suitable roof is not north facing? So what are my options?
A grid connect solar system will generate in New Zealand the most solar electricity when the LG solar panels are facing north at a tilt angle of 15 to 30 degrees.
In general also consider a North/West or fully Western facing roof for your system, especially if you use air-conditioning after 2pm.
In summary solar modules can be facing anywhere from East, through North to West, and still provide good output performance. Think about the consumption you will have during the day and this can help you locate the solar panels in the best possible way. If you use lots of electricity in the morning, go for an Easterly roof. If you use lots of electricity during the day, go for North roof and if you use lots of electricity in the early and late afternoon – settle for North, West roof. With multi-string inverters you can also put one group of solar panels (one string) on the East and one onto the West – to cover a wider time span.
If you don't have any suitable roof, LG solar panels can be fitted to a ground mount system, maybe even with a tracker on a sunny spot on your land. Please allow for additional cost in regards to ground mounting systems for cable runs etc. Discuss the options with your local LG solar dealer.
