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).
Buying a home solar system. If youâre buying a home solar system, how much can you expect to pay? The average cash price of a residential (photovoltaic) PV system ranges from $15,000 to $40,000, depending upon home size and utility bill, but the old adage, âYou get what you pay for,â applies. Not all solar systems are alike.
