Off-Grid Advantage in Rural Mijas
For properties >500m from the electrical grid, off-grid systems are more economical than grid connection. Plus, they provide complete independence and protection against price increases.
Frequently Asked Questions
An off-grid quote follows assessment of seasonal demand, peak and starting loads, site-specific generation, usable storage, reserve, load shedding and any generator. Include protection, siting, fuel, maintenance, replacement and applicable procedures.
Use measured seasonal energy and power demand, winter generation, usable capacity, allowed depth of discharge, reserve and an agreed outage/load-shedding strategy. Floor area alone cannot determine array size or autonomy.
Model the actual site across seasons and prolonged poor-weather periods. Winter output cannot be assumed to be a fixed share of summer. Reserve, load shedding and any compatible generator strategy must be designed; year-round availability is not guaranteed.
Obtain the distributor connection assessment and compare its full scope with an engineered off-grid proposal. Include energy purchases or generator fuel, maintenance, battery replacements, finance and operating constraints. Distance alone does not determine the cheaper option.
Options can include suitable additional storage or a specifically engineered generator arrangement. Check inverter/generator compatibility, protection, switching, earthing, fuel, emissions, ventilation, noise and procedures. Wind requires a site resource and structural assessment; arbitrary sources cannot simply be combined.
A grid-connected hybrid inverter does not automatically provide off-grid operation. Backup needs an approved compatible configuration, safe grid isolation, earthing/protection design and defined circuits, loads and reserve. Transfer and runtime depend on the equipment and load.
