But, an aquaponics greenhouse can minimize trips to the grocery store, eliminate the need for plastic packaging, eliminate shipping from farms to stores, and provide healthier non-GMO nutritious foods. That saves a huge amount of wasted energy. "A kilowatt saved is a kilowatt earned."

@MaddHatter That's why batteries shouldn't be discharged over 50%. I also noticed that there was no mention of a battery management system, aka BMS. It's built into the Tesla Power Wall. But, he incorrectly stated that batteries can be powered directly from the solar panels' DC output. Charge currents must be well regulated and match the battery type. Battery technology is the holy grail for sustainable energy. There are many companies frantically conducting R&D on alternatives to LiFePO4 to become #1. It's only a matter of time before inexpensive reliable batteries are on the market.
