Solar PV, Aberdeen and me - Update 3

May 062018

I am currenly holidaying in sunny Gran Canaria and whilst dozing by the pool, I caught sight of a bank of solar panels. "Ah" I thought, I have those.

Its also been a while that I last blogged, so I thought I would kill two birds with one diamond laser and post an update. See graph.

It has been up and down with the generation rate but it has surpassed the conservative expectation that the installer gave me. Quite pleasing. The generation estimate was made against the avg Aberdeen sunlight hours, direction of panels, angles etc and the performance tracks  the avergate sunlight hours/day nicely - below, yellow line.

The sunlight hours highs are May followed by August, which appears odd at first (July being the hottest month) until you realise heat and sunlight are not the same thing. It does make me want to investigate all this talk on micro heat-powered Sterling engines I hear so much about. These are dinky blacker-than-black heat traps that expand and contract gasses to drive turbines that generate UnLiMeD POWER!!@%@45£!

At a 60% to 70% efficancy rating, Sterling engines kick solarpanels and their 20% max efficancy off the ballpark. They are more complicated I am given to understand, however the clever dicks are working on the problem and hope to have something investors can overspeculate on soon [1]. When done, we can call China and ask actual ballparks of them - hurrah.
