Michael, Of course - but the energy balance is just a theoretical concept,
a beancounter's satisfaction if you will of checking that the two sides of a scale balance out - with exact specified quantities on each side of the scale, no matter whether that is practical. It is also a means to get a feeling when you install a solar system, how much energy it needs to produce before it has earned back the energy that went into making it. Something to feel-good about when naysayers claim that you are generating a net loss with all those high-energy-content panels on the roof - so it is also used to support the claim that after some 1-2 years, the panels have generated more energy than they ever costed, so it is not a net-energy-loss as some claim. Whatever your inclination - there is a whole world out there that is not accounted for when considering narrow definitions, so for a lot of practical applications, this is moot. Most people look at the money and see that their system generates money after approx 7 years. So they are happy and whoever says "but it is an energy sink" gets the reply: and what is your car? Both and energy and money sink. At least the solar panels are generating money (and energy)...

Thank you Cor, This is just me experimenting with the ideas.... Can we really disregard the energy cost of all those other items making up the totla cost? I guess can see leaving out profit (which is sort an excess since everyone involved already put food on the table, got medical care, and so on. The people drawing the profit may not have undertaken the PV at all without the promise of profit, so maybe that too is part of the cost - energy wise, but it isn't clearly so); but the energy to transport the panels afterward, to market them, to shuffle salesmen and installers around, the energy cost of the inverters, disconnects wiring, lights and heating in the installers physical plant. Wouldn't all these be foregone if the panels were never made? -------------- next part -------------- An HTML attachment was scrubbed...
