Information About A Passive Solar Greenhouse

A passive solar greenhouse allows plants to grow year round. The greenhouse allows delicate plants to survive when there is frost outside and temperatures drop below freezing. Passive solar energy allows heat to be stored so there is no need for additional heat at night when the sun is no longer shining and temperatures tend to drop to lows.

Traditional greenhouses are often heated with gas to prevent freezing. Since the walls are single thickness much of the heat is lost to the outside. While the system works well, it can be very expensive. Using passive solar heat keeps the plants warm but at a much lower cost than using gas. Three of the exterior walls are made to be insulated and a large mass is included to store the heat.

Since traditional greenhouses are all translucent panels they can be oriented in any direction. Solar greenhouses, with the insulated walls have only one translucent wall that needs to be oriented in such a way as to take the greatest advantage of the sun. As the sun shines into the greenhouse, it warms the air in the greenhouse and the solar mass.

In the warmer months it is possible for the temperature of any greenhouse will become too warm for the healthy plants to grow. It is important that you have a ventilation system that can bring in cooler outside air. Thermostatically controlled fans can be set to turn on at a certain temperature and prevent overheating of the greenhouse.

A greenhouse can allow a home to have fresh produce even when it would normally be out of season. Using a greenhouse can ensure that you are only feeding your family organic foods that have not been sprayed with chemicals. This produce can cut the cost of your family grocery bill.

The cost to build a passive solar greenhouse is about the same as the cost to build a traditional greenhouse. The savings in energy consumption is enough to offset any additional construction costs.
