Costa Rica has many beautiful, isolated properties far from power lines and not easily accessible. Such properties are best served by independent power systems, of which solar is always a viable option unless completely under tree cover. While solar hours vary from region to region of Costa Rica, even the rainiest areas get at least an average of four solar hours a day over the course of a year.
Independent Solar Systems are much more complex and costly installations than grid-tie systems because of the extra equipment required. Independent systems require batteries and inverters to store power generated during daylight hours.
