Once upon a time

There was once a poor, ignorant peasant farmer who wanted to buy a farm

Once upon a time

So, believing the assurances of the government he bought one without mains electricity

Once upon a time

So, believing the assurances of the government he bought one without mains electricity

(which just goes to show how stupid and ignorant he was)

Once upon a time

And so for 3 years he got through a series of generators and a lot of money to provide electricity for just a few hours a day

(blowing up several washing machines and uncountable light bulbs on the way)

Once upon a time

This made him a very sad, poorer peasant but perhaps a little less ignorant (at least about generators)

Once upon a time

Then one day along came simple, inexpensive, solar power system

Once upon a time

From one day to the next he had a bountiful supply of clean, free, electricity 24 hours a day

Once upon a time

This made our simple peasant very, very happy, eventually a lot less poor, and with every expectation of living happily every after.

Why

320 days of sunshine per year Ecologically friendly Reliable Clean ‘Free’ energy Increasingly cheaper to install Low maintenance

Why Not?

Building Licence for Panels ‘High’ cost of installation ‘High’ cost of upgrade Space occupied Noise
