Thousands of people have spent vast sums of money installing eco-friendly
solar panels but most will have probably had them fitted facing the wrong
way, according to energy experts.
The solar power industry is being urged to reconsider its approach to
installing panels after one of the UK’s leading experts, Professor Ralph
Gottshalg of Loughborough University says too many solar panels are facing
in the wrong direction.
Professor Gottshalg said Germany has too many solar panels which means that
its grid is disrupted on sunny Summer lunchtimes with a flood of solar power
so cheap it has to be almost given away.
He is urging to the UK to follow Germany’s recent policy of putting panels on
east-west facing roofs to smooth the supply of power during the day and
prevent spikes of power at midday.
Conventional wisdom in the northern hemisphere is to face solar panels south
so they get the most exposure to sunlight during the day.
And, of course, that is precisely the correct direction if your goal is to have a source of power for your battery banks in the event of a grid-down situation.
Not that anything like that could ever, ever happen.
