Technical FAQs 4

Can solar panels be installed on a north-facing roof?

If your roof is north-facing and not your run-of-the-mill shape, adjustments can be made to accommodate solar panels. Shading over the roof: Any surrounding trees may need to be trimmed back to allow for as much sunlight as possible. Other immovable structures that are throwing shade on your roof for the majority of the day may pose a bigger issue.

What angle should solar panels be on a north-facing roof?

For panels on a north-facing roof, the recommended angle is between 10 ° and 20°. If your roof space allows for it, increasing the number of solar panels can be highly beneficial for homes facing north. This allows for higher energy production and may shorten your ROI period.

Can a 5kw solar panel fit on a north-facing roof?

I can only fit about 5kW of panels on the north-facing roof. If Max loses a quarter of his energy to shading – the 5kW array becomes the equivalent of a 3.75 kW array in full sun. That’s a bit small for a modern home.

Are north-facing solar panels better than south-facing?

There is a significantly lower output from north-facing solar panels compared to those that face south. If you are living in the northern hemisphere and you have a south-facing roof with solar panels between a 20° and 50° angle the effectiveness is considered to be 100%.
