Installing a solar energy gridconnected electricity system

Electricity bills have increased by an average of 20 per cent each year over the past five years and the cost is likely to increase by similar amounts over the next few years.  
How does a solar grid-connected system work?
Solar electricity systems capture the sun’s energy using photovoltaic (PV) cells. When light shines on the cell it creates an electric field. The PV modules generate DC electricity – or Direct Current – sending it to an inverter.  The inverter transforms the electricity from DC to AC (Alternating Current) for ordinary household needs. This system allows the solar electricity to be used as it is being generated.
Do I need permission from Iberdrola to install a system in my property?
Yes. Permissions need to be obtained before the installation takes place. Every grid-connected electricity system needs authorisation from both Iberdrola and the Spanish Government. Iberdrola is currently issuing fines of up to €30,000 for unauthorised installations.
What is the life expectancy of a solar grid-connected electricity system?
A well-designed solar system will last for 25-30 years. Both solar panels and inverters we use are guaranteed for 25 years.
Does solar energy only work on sunny days?
No. These cells don’t need direct sunlight to work – they can still generate electricity on cloudy days.  The stronger the sunshine, the more electricity is produced.
What happens to the electricity that is produced but not used?
Iberdrola will now buy back any solar electricity that is sent back to the grid.  
Do I have to pay tax to the Government if I install a system?
Two  years ago the government published a draft proposal which proposed a tax on electricity that was produced and consumed from solar grid-connected systems. However, it was met with enormous opposition. The proposal has effectively fallen by the wayside.
