Connecting solar panel into domestic electrical circuit

If I bought a solar panel to take abroad could I link it up directly to the
house electricity cables after the voltage meter?
Would this draw less power from the grid during the day?
Kindest regards, Saiduz.

Unfortunately it's not that simple! Solar panels produce DC electricity, usually at 12 volts, which is fine for battery charging. But it's not compatible with 240 volt AC mains electricity. You can use an inverter (eg the Silverline Inverters or Steca Inverters on our website)  to produce mains electricity from the battery that you have charged, but even then you can't simply plug that electricity straight into your mains circuit, as the frequencies they are running at will be slightly different and out of phase. Any equipment running off the inverter would have to be on a completely seperate circuit.

It is possible to get a type of inverter which can connect into your mains electricity. However these 'grid-connect' inverters are far more expensive, and only really suited to big arrays of solar panels.
