Casa Guadiana is an eco-house. Its electricity supply comes from solar panels and as such is limited. It therefore requires sensible management of power use. There should be enough power for lighting and charging phones and computers, but you should turn off lights when not needed and avoid leaving anything on all night long as this prevents the system going into hibernation mode.
The washing machine can be used when the sun is shining on the panels, but other heavy-duty items with heating elements such as hair dryers, curling tongs and irons must NEVER EVER be used as they risk damaging the system.
There is no internet access at Casa Guadiana but there is a public wifi internet service and computer terminals available for public use in Alcoutim library for a nominal fee. There is also wifi at the Riverside Café. There is a weak mobile phone signal on the terrace at Casa Guadiana but if you drive 2km back up the road you’ll get a full-strength signal.
