How fitting a Suntile can save you £££s

We think it’s possible to save at least £30 a year off your electricity bill.

Here’s how we worked it out.

In full sunlight, one Suntile can produce the equivalent to a thousand watt light bulb. This country isn’t Barbados, it’s England so we thought we’d be conservative and take it to 300 watts in a five hour day.  Of course in summer we can have up to 16 hours of daylight but in winter it can only be about three so let’s say five. 

Because most of us have the odd holiday, visit the occasional relative, go to work etc, we took this five hour day and instead of saying it was five hours a day for seven days a week, we said a five hours day for five days a week.  So instead of 365 days a year, this calculation is based on 260 days a year.  With us so far?

300 watts, five days a week, so 260 days a year = 390,000 watts per year (390kwh)

OK?

The current cost of electricity is about 7½p per kilowatt.

£0.075 x  390kwh = £29.25.

So that’s why we say ‘at least £30 a year’ which we think is pretty conservative.

Of course, at Suntile, we think the savings to the environment are actually a bit more important than material savings.  We like Polar bears, Penguins, Sea Lions and all those endangered species up there on the ever decreasing Ice Cap.

Take the above 390kwh:
For a coal fired power station to generate that power, it would produce around
150kg of carbon dioxide (greenhouse gas)
800g of nitrogen dioxide (smog)
1kg of sulphur dioxide (acid rain)
For a nuclear power station to generate that power, it would create about 13g of high level nuclear waste.
… and all that is just one Suntile’s worth of savings.
