Photovoltaic electric power

More and more people talk about photo-voltaic electric power which can be obtained independently by a home. Many things are said but what is essential about this matter is usually omitted. It is not profitable.

The materials and equipment needed for a photovoltaic system are very expensive and can damage very easily. The amount of electric power generated by a photovoltaic system depends greatly on weather: if it is sunny or cloudy. Because the electricity consumption does not take place simultaneously with its production, electricity storage is needed. The storage is made in batteries which are very bulky and heavy.

The most profitable way (at least at this moment) is still the old way: to be connected to the National Power Grid. Electricity produced by electromagnetic induction is not stored and it is based on the fact that not everybody consumes electricity at the same moment, so overall it fits to the optimum parameters of consumption.
