Geodes differ from vugs in possessing an outer mineral layer which is more resistant to weathering than the host rock. As such, complete geodes commonly weather out of rock exposures and accumulate in canyons, talus, rock detritus, etc.eodes differ from nodules in that a nodule is a solid mass of mineral matter, but some nodules may have a tiny void space in their interiors and the distinction between a geode and a nodule may be barely discernible if the cavity is miniscule.
As mentioned in the introduction, residential solar systems are typically sized from 3 to 8kW and end up costing somewhere between $15,000 and $40,000. In this section, we will look at the costs of the various components of a solar system (not installation or operational costs).
Why Solar Energy? A typical residential solar PV panel system in the U.S. costs $3.60/watt after installation, and the solar panels typically save the customer over $20,000 (net) over the course of 20 years. Learn more about the many advantages of solar energy.
