Comment Re:What about tile roofs? (Score 1) 53
I hate to say it but until it can install solar onto an expensive "100 year" tile roof that is somehow also extremely fragile, I can't be bothered. My stupid 100 year tile roof would cost over $80,000 to replace, and "market rate" maintenance is about $150 PER TILE.
Until solar can be safely installed on THAT kind of roof (very common in my area), it's just something that other people do.
I have concrete tiles on my roof. They look a bit like terracotta tiles but they are just moulded concrete. They are just over 50 years old. In 2020 we hadd 5.6kW of photovoltaics fitted on the roof. The photovoltaics were mounted on rails about 100mm above the roof. The rails are attached to the same timber battens that hold the original tiles, which remain in place. We had to replace a dozen or so tiles after the solar panels we fitted due to the accumulated 50 years of damage and some additional damage from the contractors who fitted the panels.
The rest of the roof was left as-is. The roof doesn't look "new" but it keeps the weather out like it did when it was new. The solar panels shade the roof so we need less AC in summer. Barring some kind of never-before-seen-in-our-area weather event I expect to get at least another 30 years out of the roof + panels (The panels have a 25 year warranty) though we may add more solar and a battery before that.
