Tigo optimization contributes 4,854 kWh of Reclaimed Energy, representing 25% of monitored solar production at a tree-shaded campsite
Camping La Toma del Agua, located in the wooded countryside of Riópar in Spain’s Albacete province, operates entirely off-grid. The campsite historically relied on a diesel generator to supply its electricity, with annual fuel expenses of approximately €70,000.
The owner engaged AURA Ingeniería Energética to reduce this dependence through a solar-plus-storage installation that would respect the site’s natural surroundings. Commissioned on July 1, 2026, the system combines 116.59 kWp of solar capacity, 228 kWh of battery storage, and Tigo module-level optimization.
Available rooftop space was spread across multiple buildings, roof sections, and orientations. Mature trees cast partial shade on different parts of the array throughout the day, creating uneven module operating conditions and recurring mismatch losses.
Preserving the trees was central to the project. AURA therefore needed to make effective use of the available rooftops while managing the impact of shading. Solar generation and storage also had to support the campsite’s electricity needs and reduce generator use.
Electrical safety was a further consideration in this rural, wooded setting. AURA sought module-level technology with rapid shutdown functionality to help reduce DC voltage during an emergency.
AURA’s approach began with the campsite’s operating needs. As Sergio López, CEO of the company explains:
“At AURA, every energy project starts with understanding the customer’s business: how they consume energy, when they need it, and where they can reduce costs. That understanding guides the technology we select and how the system is managed. Our work goes beyond installing solar panels. We focus on energy management so that each installation meets the day-to-day needs of the business.”
For Camping La Toma del Agua, the resulting design uses 178 LONGi 655 Wp PV modules, each equipped with a Tigo TS4-A-O optimizer. Module-level optimization helps reduce mismatch losses by limiting the effect of an underperforming module on others in the same string.
Cloud Connect Advanced (CCA) and Tigo Access Points (TAP) support communication with the TS4-A-O devices. Through the Tigo Energy Intelligence platform, the operator can review individual module performance, observe the effects of shading, and identify potential issues across the dispersed rooftops. The platform also reports the additional energy attributable to optimization as Reclaimed Energy.
The TS4-A-O devices provide rapid shutdown functionality, addressing AURA’s requirement to help reduce DC voltage for safer intervention during an emergency.
The PV array is integrated with a 110 kW three-phase Sigenergy hybrid inverter and a Sigenergy SigenStack storage system comprising 19 battery modules of 12 kWh each. This configuration allows solar electricity to be stored for use when generation is insufficient, reducing reliance on the diesel generator.
According to AURA Ingeniería Energética, the campsite can now meet its electricity needs throughout the summer without operating its generator. Remaining winter fuel expenditure is estimated at €15,000 per year. Compared with the previous annual diesel bill, this represents projected fuel savings of €55,000, or approximately 79%.
Monitoring data also quantifies Tigo’s contribution. Between July and October 2026, the Energy Intelligence platform reported 4,854 kWh of Reclaimed Energy out of 19,454 kWh of total monitored PV production, a share of approximately 25%.
Reclaimed Energy accounted for 23% of monitored production in both July and August, 26% in September, and 31% in October.
For the campsite, the installation provides a way to reduce diesel use while retaining the trees that define its setting.
