PV solar panels, or as they are often referred to photovoltaic solar panels are speedily becoming more and more efficient as the technology of photovoltaics advances. Solid state silicon PV panels are now nearing the theoretical top efficiency of 29%, a figure that is determined by the thermodynamic physics of reflectivity and thermodynamics. Coupled with these technological advances, production costs have also fallen which means the whole economics of solar panels has now got favourable even in cities where the sun’s strength is not very large. Indeed pv production businesses are beginning to boast of fabrication costs less than 65c per watt or $65 per kilowatt or better.
Whilst for manufacturers the target is the concept of grid parity – a price performance level at which photovoltaic panels match current electricity generation costs – for electricity consumers in Britain, the market is even better with feed in tariffs positively incentivising businesses to install free solar panels. Such free solar panel installations typically require a house to be south facing in order to maximise the free power available from the sun.
Grid parity is already being obtained in high sunshine places such as Hawaii but that doesn’t mean that a significant contribution to a household’s electricity usage can’t be supplied in less tropical locations, particularly because solar panels generate electricity at some level during all daylight hours. This on-going, steady generation means that one of the most sensible ways of utilising panels is to connect them directly to the national electricity network. This lets the delivery of any excess power to the national network for use by other households and businesses and ensures that if the greatest solar power production happens not to overlap with the household’s own peak demand, power is not just wasted. Additionally, the householder is credited for power fed into the grid, often at premium rates.
In the United Kingdom home installation companies of PV solar panels are given an economic incentive to do this under a scheme known as the renewable heat incentive which pays high prices for an kilowatt hour of energy fed to the grid. Consequently we can expect to observe the steady growth of solar panel usage, particularly across the south of the UK where insolation levels are highest.
