storage options for solar do exist but they are only marginal improvements. renewable credit systems are retarded and are a glaring hole in the viability of renewables. just because you gave me a kilowatt last week doesn't necessarily mean i have one to give you in return next week, see peak demand. this is somewhat like like giving a bushel of corn to market in a farming village and asking for it back during a famine. the best power production is strong in all weather, never needing credits as it can produce 24/7.
