A green energy company is installing solar panels for free and then selling the electricity to the owners at a reduced price.

Electron Green is to maintain more than 200 solar panels on a factory owned by PPE manufacturer, Respirex, in Redhill.

The electricity is then to be sold back to them, saving the company more than £500,000 over 25 years.

Respirex says it gives them certainty about long-term energy expenditure.
