Gransolar’s ISE Energia delivers 10-MW PV for Cajamar bank

• ISE Energia commissioned 10 MW of solar in Almería for cooperative bank Cajamar, providing contracted clean power and long-term cost stability.

ISE Energia, the EPC arm of Spain’s Grupo Gransolar, has commissioned 10 MW of photovoltaic capacity for cooperative bank Cajamar in Almería, southern Spain, marking a sizable corporate deployment that ties energy costs to predictable solar output. The scheme is structured to deliver contracted clean electricity with clear visibility on savings and carbon reduction.

Technically, the build follows a bankable blueprint: high-efficiency modules, string inverters for granular fault isolation, and SCADA systems that track performance down to string level. Depending on site mix—ground, rooftop or carport—the arrays use fixed-tilt structures optimised for Almería’s irradiance and wind, with DC/AC ratios sized for strong annual yield rather than headline peaks. Curtailment response, reactive-power support and ride-through functions align with Spanish grid codes.

For Cajamar, the benefits are practical and reputational. On-site and dedicated solar supply hedge electricity prices, reduce Scope 2 emissions and create an ESG-credible story for customers and regulators. Pairing the PV with energy-management software allows demand-side optimisation across branches and data facilities, nudging loads into high-generation hours. Carport arrays can add shade and enable EV charging, extending the bank’s sustainability narrative to staff and visitors.

Construction was delivered with the now-standard community and environmental safeguards: traffic and noise controls, storm-water management sized for heavy rain, low-reflectivity module placement to mitigate glare, and landscaping to soften visual impact. End-of-life provisions point to responsible recycling pathways for modules and balance-of-plant components.

The operational focus now shifts to first-year stabilisation: thermal inspections to spot underperforming strings, cleaning schedules calibrated to local dust, and inverter set-point tuning. Incremental gains here compound into higher output and better economics over decades.

In Spain’s maturing corporate market, Cajamar’s 10-MW package is a template—scale, standardisation and measurable emissions cuts—showing how finance can underwrite its own clean-power transition.
