Building Solar on a Forested Property: What Shading Really Costs You Building solar on a forested KZN property meant solving a shading problem before solving an energy problem. R35,500 in structural and arborist work later, the system peaks at 3,794W on clear days and 1,158W on heavy overcast — the honest production range on a shaded South African winter installation. What the data shows, what it cost, and what I would do differently. Read More →
