Using Passive & Active Solar Heating Systems in a Hobby Greenhouse
Let the sunshine in, using solar energy to heat your greenhouse will save you money! All greenhouses are solar heated to some extent, anyone who has been inside for a few minutes on a summer day knows how warm the sun can be. A greenhouse acts as a natural solar collector but it cant retain the suns heat at night. Consequently 75% to 80% of the cost of heating a greenhouse by conventional energy sources is expended at night. To retain the suns heat you need something the heat can be stored in a heat sink. Heat sinks can consist of barrels of water, rocks, concrete walls or some other thermal mass. At night stored heat radiates throughout the greenhouse.

Add Mulches To Protect Plant Roots
Another way to protect plants over the winter months is to use mulches to protect plant roots. Laying a thick mulch or ground cover over the soil can help avoid the need for extra heating.
For example, it could allow you to successfully overwinter root crops and alliums in colder climates without finding a way to heat your greenhouse.
Mulches that could be useful for this purpose include: straw, bracken and sheeps wool, for example. Heres a full list of garden mulches to consider.
Whether or not you actually need to heat your greenhouse this winter, think about heat energy where it comes from and where it goes. This can help you make the best choices long term both for your own growing endeavours, and for future generations.
Maximize Light And Heat In The Winter
Solar greenhouse design and passive solar design in general relies on the premise of strategically controlling light and heat gain. Namely, you want to maximize light when it is absolutely needed and reduce light when it is abundant and creates too much heat .
Its important to keep in mind the angle of the sun during different seasons, as shown in the graphic above. In the winter, light comes in at a low angle and in the summer it is much higher in the sky . Thus, on vertical South surfaces, you want to use a high light-transmittance material, such as glass, to absorb as much of this light and heat as possible. You do sacrifice insulation at night, but at this time of year light and heat gain are the top priority. Thermal mass should be used to store some of this heat for temperature regulation. You can also angle the South face of your greenhouse so that it absorbs more light as shown in the commercial solar greenhouse below.

The Downsides Of Solar Air Heaters:
The Achilles heel of most renewable energy generators like solar air heaters is reliability, but also energy storage. The wind doesn’t always blow and the sun doesn’t always shine . So the main drawback of solar air heaters is that you only get heat when the sun is shining.
Short winter days and unpredictable cloud coverage make it difficult to rely on solar air heaters as a primary heat source because you will gain all your heat during sunny hours but then have to go an easy 16 hours at times with no heat input. And shorter days in winter means that they generate the least amount of heat when you need it most – though this can be mitigated by south facing wall mounting. In all but the most heavily insulated homes in more gentle climates, with thermal mass included for heat storage, you will likely need an additional heat source like high efficiency wood-burning stoves or fireplaces, or if off-grid an electric-free wood pellet stove.
Orient The Greenhouse Toward The Sun
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 . 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.

How To Heat A Greenhouse With Solar Panels
Exploiting natural resources to make industrial processes more ecological is the flag of agricultural technology these days. At the moment, solar panels are not among those devices which are unrelated to greenhouses or crop fields. Solar power is used to create clean energy to heat a greenhouse. Besides heating solar panels are also used to power automatic irrigation systems, lighting, or anything else that is powered by 110V or 220V. Believe it or not, the world is slowly changing to become a better place! If you want to be part of the change, stay with us, and learn how to heat a greenhouse with solar panels.
Fireplace Insert With Heat Extender Using Fans
Another practical option in heating a greenhouse using solar energy is finding another heat source aside from heaters.
In this setup, we will use a wood-burning insert as the heat source and utilize solar-powered fans to regulate the heat in the greenhouse from the top to the ground.
In this setup, we suggest placing a wood-burning insert if youre in a location with freezing temperatures.
Then, place a heat-powered stove fan on top of the wood-burning insert to distribute the heat throughout the greenhouse. Also, you may set up your off-grid solar system beforehand as mentioned above in this post.
Then, with a running solar system, connect an outlet extension to the inverter and connect the temperature-sensitive switches. These switches have a sensor that only turns on an appliance connected to it when it reaches a specific temperature. It helps ensure that the fans will only run when needed. Place the switches near the location of your fans.
Next, set up the fans around your greenhouse and plug them in the temperature-sensitive switch next to it. If youre going to use more than one fan, you may add another battery to help sustain the energy demand.
To check if the heat is distributed well, place a temperature monitor on top of the greenhouse and below.

How The Climate Affects Your Greenhouse
Greenhouse gardening can be affected heavily by climate change. It will be easier to maintain the house in hotter climates as you only have to be alert about letting the excess heat out. In colder temperatures, it takes extra effort to maintain the heat and the plant. It might need more time in colder climates than usual to grow a plant as the weather is cold. Ensure the structure hotter in the colder climates, or tropical plants may suffer in growth. Be sensitive to the weather and climate changes.
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.This is usually where traditional greenhouses fail: they collect just as much energy as solar greenhouses but cant retain that heat when temperatures drop. Solar greenhouse design depends on adding insulation on every surface that is not needed for light collection. This means the entire North wall should be fully insulated. In addition, you can / should insulate some of the east and west sidewalls. These only get direct sun for a few hours a day and thus can lose more heat than they gain, depending on your location and climate.
How much insulation is right? It all depends on your climate and site. Look at other solar greenhouses, or contact a solar greenhouse designer who can provide a climate analysis or suggestions, to get an idea.

Thermosyphon Diy Solar Water Heater
The inner pipe system of this heater is organized in such a way that water flows from down to up in every section. The black-painted pipes are put inside a wooden box with glass top panel. But having the water inlet of the collector at the bottom and the outlet at the top, the thermosyphon effect will make hot water rise and suck cold water in. This negates the need for an extra water pump.
What Is A Solar Greenhouse
All greenhouses use the sun, but solar greenhouses harness that solar power for more than just growing tasty veggies. Traditional greenhouses made of glass or plastic usually rely on fossil fuels to provide additional heating needs during colder months. A solar greenhouse, on the other hand, creates a warm, nurturing environment all year long using nothing more than natural materials, energy-efficient design and the power of the sun.

Do You Need To Heat Your Greenhouse
Weve now explored some interesting solutions to heat your greenhouse in winter. But before you determine which plan is right for you, think about whether you need to heat your greenhouse at all.
Your greenhouse as it stands may already be sufficient to provide the protection required over the winter months without taking steps to raise the temperatures at all. The following steps might make it possible to avoid the need for additional heating altogether.
Add Thermal Mass To Regulate The Temperature
Before you think about any heating system, its important to think about how to catch the heat already in the system. Take steps to increase the thermal mass in your greenhouse.
Materials with high thermal mass catch and store the heat energy from the sun slowly during the day and release it slowly when temperatures fall at night.
Materials with high thermal mass include:
- Bricks/ ceramics
Here are some things you can do to add thermal mass that could prevent the need for winter heating in a greenhouse:
- If you dont already have a greenhouse, consider an earth-sheltered one.
- Place barrels, tanks or other containers of water inside your greenhouse.
- Add paths and bed edging made from materials with high thermal mass.

Setting Up A 250 Watt Solar Panel Based Heating System
Here is a simple Example on How you can heat your Greenhouse:
The video should give you a clear understanding of how to setup up a greenhouse heater using solar panels. The most important thing that you need to consider is the size of the heating system that you install in your greenhouse. For a small greenhouse a 250-450 watt electric heater would do the job. I think for most of the people 250-watt heater will do just fine. If you need the exact wattage for your greenhouse, you can ask us by posting a question in our Forum.
Things that you will need for setting up your solar panels powered greenhouse heater:
Solar Panel Kit:
You will need to buy a solar panel kit, if you are planning to build 250-watt solar heater , you should buy 500 Watt solar panel kit. I highly recommend the ACOPOWER Solar kit , this is one of the best deals you can find on Amazon.
This kit uses an MPPT controller, which is efficient than the PWM controller and it also provides cables and connectors for connecting the solar panels to the charge controller. They have provided a diagram that you can follow to connect the solar panels to the charge controller.
For heaters, you have two options. 1) Use 12 volt DC heater and connect it directly to the charge controller. 2) First, convert 12 volt DC into 110 volts AC and connect it to the AC heater. Both of these options have benefits and drawbacks. Lets discuss them in detail.
