New solar panel technology breakthrough
Fast advancing solar panel technology has made photovoltaic (converting sunlight to electric power) and solar thermal (converting sunlight to heat) installations viable even in less sunny countries like Ireland.
Yet another solar panel breakthrough won one of the innovation prizes at the recent Agriscot show in Edinburgh.
A highly commended certificate was presented to Soltropy, a startup business, for its newly invented modular solar thermal panel which does not require anti-freeze.
Solar panels used to generate heat normally have a pressurised, closed system which transfers heat to, for example, a house’s central heating. The closed system must contain anti-freeze to protect the panel from damage when the temperature is very low.
It is recommended that the system be flushed out with clean water, and the anti-freeze renewed, every few years.
However, Soltropy devised a special inner core to make panels ice-resistant, a system which is also claimed to be three times more efficient than conventional solar panels.
It’s good news for farmers who use solar panels to generate hot water in the milking parlour, or in the home.
