Well the best solution is probably nuclear meeting the base load while solar helps with daytime peaks.

But otherwise pumped storage has promise. Have 2 reservoirs at different elevations connected by a turbine and pumps. When there is excess power durning the day, pump water to the upper reservoir. At night, let the water flow by gravity to the lower reservoir through a turbine and make power.

Transoceanic power transmission is just too expensive.
