Have questions?

    • Useful starting information includes your project location, what equipment needs power, expected energy use, seasonal or year-round operation, existing electrical equipment, available generators or charging sources and your priorities for backup and reliability. RES can use that information to help determine what additional site assessment or system planning is needed.

    • Solar can contribute to battery charging and onboard electrical needs in marine applications. The appropriate system depends on the vessel, available installation area, electrical loads, battery system and other charging sources.

    • Yes. RES works with RV and mobile power applications. System design can account for available installation space, expected loads, battery capacity and available charging sources.

    • Yes. Cabin systems can be designed around seasonal or year-round use, expected electrical loads, available renewable resources, battery storage and backup power requirements.

    • Yes. RES works with residential, commercial and remote applications and can evaluate renewable generation, battery storage, generator integration, electrical infrastructure, controls and ongoing support as part of a complete system.

    • Yes. Generators are commonly integrated with batteries and renewable generation in hybrid power systems. The system can be designed so each energy source supports the site’s operating requirements.

    • Most fully off-grid solar applications require some form of energy storage or another source of power for times when solar generation cannot meet the load. The appropriate battery capacity depends on energy use, desired autonomy, seasonal conditions and the overall system configuration.

    • Solar can be part of an Alaska off-grid energy system, but system design needs to account for location, seasonal solar availability, electrical loads and the other energy sources available at the site. Battery storage and generator backup may also be incorporated depending on the application.

    • A geothermal system uses underground loops and a heat pump to transfer natural heat between the earth and your building, providing highly efficient heating and cooling without generating heat.

    • Yes, RES manages permits, inspections, and utility coordination.
