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).
Generally, Solar PV systems that generate electricity from sunlight cost between $2.50 to $7 per installed watt. Typically, the larger the system, the lower price per watt.Large commercial systems are typically well below $4 per watt.Residential systems, because of their smaller size are usually somewhat higher. For example, in Ohio a 5 kW residential system with an average monthly production of about 530 kWh would cost approximately $19,000 or about $3.77 per watt.Larger systems have a significantly lower cost per watt.or example, in Ohio a 5 kW residential system with an average monthly production of about 530 kWh would cost approximately $19,000 or about $3.77 per watt.
