Hello Solar experts,

I am wondering whether the cost, subsidised or not, of a domestic PV solar installation may be set to come down.

My house roof orientation is not ideal for solar panels but I have a flat-roofed studio in the garden that is not overlooked and which could be a good site.

But my main question was whether anybody had knowledge/experience of orientation sun tracker systems. I read that the overall efficiency could be increased by up to ~30% by optimising solar capture and I would like to know whether the cost or complications of a tracker system make this viable? Am even wondering whether a diy system might be feasible?

Many thanks for any insights.

Chris
