You'd need to check on your local energy providor.
In certain areas the local utility gives rebates on it.

When its a new system in the area (and they are promoting
it) you might be able to get locked in at a great rate when
sending electricity into the grid. Over the course of a few
years the system can pay for itself depending on your area.
The higher the chargeback fee the faster it'll pay for itself.

Quick but maybe trick question:
My house does not need extra-power supply. a couple oftvs, fridge, 2
computers, washing machine (not on all the time)... etc

Would it be possible to get solar panels to produce enough energy for
the house? if so, are these things stupidly expensive or it is worth
the cost? (I have sun most of the year, including winter)

Thanks.
