What is a solar greenhouse? Don’t all greenhouses use the sun? Well yes, but a solar greenhouse uses the sun’s energy not only for growing, but also to provide all of the greenhouse’s heating needs. In contrast to traditional all-glass or all-plastic greenhouses, which often rely on fossil fuels to grow year-round, solar greenhouses can create warm year-round growing environments using only the power of the sun, natural materials and energy-efficient design. As a result, they can grow much more --citrus, avocados, fruiting tomatoes - year-round using less energy, water and resources.

 Here are the seven basic elements of solar greenhouse design. By following these, you can create a naturally abundant, self-sufficient growing oasis, allowing you to grow more with less energy and hassle. For more on designing your own solar greenhouse, see The Year-Round Solar Greenhouse: How to design and build a net-zero-energy greenhouse, which includes how-to info as well as many case studies for tailoring your structure to any climate.

1. Orient the Greenhouse Toward the Sun (the South)

This is where solar greenhouse design begins: the sun. The sun is not only your source of light for growth in the greenhouse, but your source of heat. Thus, if growing year-round in cold climates, you need to capture enough solar energy through your glazing to heat the greenhouse. Glazing is just a word for transparent materials, such as glass or clear rigid plastics. All these light-capturing materials should face where light is coming in: the South if you are in the Northern hemisphere (*For the rest of this article we’ll assume a location in the Northern hemisphere). The sun moves higher and lower throughout the year, but it is always South. A very small percentage of light comes directly from the North, and thus these sides are better off insulated.



2. Insulate the North and Everywhere Else

Solar greenhouse design depends not just on capturing enough solar energy, but trapping it in order to keep the greenhouse warm enough during cold periods.

I used the plans at WWW.EASYWOODWORK.ORG to build a greenhouse – I highly recommend you visit that website and check their plans out too. They are detailed and super easy to read and understand unlike several others I found online. The amount of plans there is mind-boggling… there’s like 16,000 plans or something like that for tons of different projects. Definitely enough to keep me busy with projects for many more years to come haha Go to WWW.EASYWOODWORK.ORG if you want some additional plans :)
