Grid Tie Inverters
For most people a simple system
containing a few PV solar panels, leisure baterries and an
inverter is their starting point, however it is now possible
to expand this simple system and make some positive savings.
You can achieve this by adding a 'Grid-Tie Inverter', these
range in price from about £75 to £1,000 plus.
They are more or less plug and play as they come with a lead
and plug ready to plug into you house electricity supply (some
bigger models do need hard wiring and a qualified electrician
would be recommended).
It works like this, supposing
you were using the PC and a few lights in your home which
in total were drawing about 150 watts and you had a couple
of solar panels connected to a 'Grid-tie inverter' plugged
into your home 13 amp power socket supplying 200 watts of
power. Then your PC and lights would be powered entirely by
your solar panels and the 50 watts surplus would be lost to
the national grid. Like wise if your PC and lights etc totalled
250 watts then you would only be using 100 watts of grid power
and you would be making a saving on you grid power supply.
Very soon this page is having additional work commissioned
with circuits and trials reported on.
