I am planning to build a solar powered(solar PV system) greenhouse. I prefer a passive solar design and solar panels that produce electricity to power equipment in the greenhouse like fans, pumps, lights.I found an interesting article on solar power trends to watch in 2017(http://www.cestarcollege.com/blog/solar-power-trends/5-inter...). I believe integrating solar panels would allow an energy efficient greenhouse to be net-zero energy or possibly off-grid. This, in turn, ensures an abundant source of food which is entirely self-powered and self-heated. I believe it would make me self-reliant, providing a reliable source of power reducing carbon emission.
