Stand-alone solar power systems are incredibly useful in areas with limited (or completely unavailable) utilities. Using a completely off grid solar systems requires some extra equipment in the way of batteries and/or other energy storage devices, but the result is complete independence from any outside utility provider. One of the pitfalls of the off-grid solar system is that you often waste unused energy, as battery storage is limited. In certain places, there are also regulations that dictate that residences and businesses must be tied into a grid. Going off-grid means complete utility freedom, but if this is the route you take, it’s best to invest in some heavy-duty solar storage devices and to double check all local laws and regulations to make sure off-grid is an option for your area.
