How to Design a Solar Greenhouse for Your Garden

A solar greenhouse in your garden is the perfect way to grow fruits and vegetables year round. The greenhouse uses the sun for heating and growing your plants. During the cold winter months, a solar greenhouse can create a warm environment for all your growing needs. However, if you’re planning on building a solar greenhouse in your garden there are a few things you need to know. 


When deciding on a place for your solar greenhouse, it’s pertinent to find the perfect location in your garden. You’ll need to face the greenhouse towards the sun to maximize your energy needs. Find the perfect location that will allow you to capture enough energy from the sun to heat your greenhouse year-round.


Insulating the greenhouse is important to keep the heat inside. Therefore, it’s important that you add a layer of insulation to the ground of your greenhouse. When the temperatures drop outside, the greenhouse will stay warm inside.

Wall Insulation

To help capture enough heat from the sun, it’s important to insulate the north wall of your greenhouse. Insulating the north wall and part of the west and east walls will help hold the heat inside your greenhouse during the colder months of the year.


During the summer months, it’s important to decrease the amount of light in your greenhouse. The hottest months of the year generate too much heat inside your greenhouse. Therefore, it’s a good idea to use a light-diffusing glaze on the roof.


During the colder months of the year, it’s important to increase or maximize the amount of light in your greenhouse. This keeps your greenhouse warm during the cold winter months.


Every greenhouse needs ventilation to keep the air moving and the greenhouse cool for your plants. Therefore, it’s important to place vents in your greenhouse to help control the temperature. Place intake vents around the bottom of your greenhouse to draw in the cooler air from outside. Afterwards, place exhaust vents around the upper walls of your greenhouse. As the heat rises the vents force the heat outside.

Thermal Mass

Your greenhouse will need a system for storing thermal mass. In a greenhouse, water will act as your thermal mass. The water in your greenhouse will store four times more heat than air alone.
