Today, it’s challenging to find something pure. Even if you ignore other essentials, no one can overlook the importance of hygienic food items, especially vegetables and fruits.
Growing vegetables by yourself at home not only ensures their purity but adds an extra flavor to them. A greenhouse lets you grow plants all year long without a pause.
However, you need to provide proper heat to get the best out of your greenhouse. One of the more recent and most energy-efficient ways is using a solar heater for greenhouses.
But, it may be a bit difficult for you to find suitable heaters for a greenhouse if you aren’t experienced.
By and large, installing a new heater in your greenhouse is not as pricey as you may think. You can easily get your hands on quality heating equipment with a bit of effort.
Here’s a guide on how to select a suitable solar heater for greenhouses. In addition, we will also discuss some of the best solar heaters for greenhouses.
Solar-powered Heater for Greenhouse
Conventional greenhouse heating techniques such as using electric or gas-powered heaters are expensive, to say the least. Moreover, they are unreliable too as a power cut can ruin your whole hard work in no time.
Therefore, seemingly, solar heaters are the correct answer to all your greenhouse heating needs. They are cost-effective and provide a continuous source of energy even on the days when sunlight is low.
Moreover, they help provide heat to the plants throughout the year, even in winter, leading to a healthy greenhouse environment.
Generally, there are two types of solar panels that are incredibly efficient including:
Monocrystalline Solar Cells
Made from monocrystalline silicon, these cells have a dark color and cylindrical shape.
These cells consume small space and have an efficiency rate of 15-20% that is above average. In addition, they show high performance even on cloudy days.
However, a drawback associated with them is that they might be more expensive than the other solar cells in the market.
Polycrystalline Solar Cells
Unlike monocrystalline cells, the production of polycrystalline cells has no silicon waste. Also, the high temperatures do not affect them negatively. In terms of costs, polycrystalline cells are more affordable than their counterparts.
Nonetheless, they tend to occupy more space and are less efficient than monocrystalline solar cells.
Things To Consider When Choosing Solar Heaters For a Greenhouse
Finding a solar heater that best fits the greenhouse can be tricky for someone with no prior experience. However, with care and guidance, you can get your hands on a product that is worth the money.
There are some factors that you must keep in mind before buying a solar panel greenhouse kit.
To start with, the solar panels for greenhouse heater will hugely depend on the size of the greenhouse itself. If you have a big outdoor greenhouse, you will undoubtedly need to have strong panels.
Plants Inside the Greenhouse
Secondly, the type of plants you are growing or want to grow decides what kind of solar heater you need. The reason for this is every crop requires a different temperature.
For instance, if you are growing plants that need more heat in winter, using small heaters for a greenhouse won’t do the job.
Moreover, plants release heat of their own too. So, if you are not consuming the entire greenhouse, then even a small heater will be sufficient for the purpose.
Level of Insulation
Another essential thing to consider is how well your greenhouse is insulated. You should insulate your greenhouse well enough so that the heat leakage is minimum. It will allow you to buy even small solar panels for a greenhouse heater.
Handy Controls in the Panel
Ideally, the panel should have some user controls to help you regulate them more easily. They may include;
- A controller for overcharging
- Mounting bracket
- Temperature sensors
- The additions like these make your panel more trustworthy and secure.
Easy to Install
The solar panel must be easy to install with a direct mount option. Moreover, some panels are also versatile in terms of installation. You can fix them on a boat, cabin, or any rough surface.
You will find a variety of solar heaters for a greenhouse in the market with different price brackets. So, before going out to buy one, you must at least have a rough estimate of your budget. This will save you much time and effort.
Advantages of Solar Powered Heater for Greenhouse
Apart from just effectively heating the greenhouse, a solar heater has other benefits too.
Here are the potential pros of using a heater for greenhouse that is solar powered.
Although it may look somewhat expensive at first, a solar-powered heater is highly cost-effective in the long run. As a solar heater will use the sun as a source of energy, you won’t have to worry about monthly charges.
Generally, the electricity or gas heaters mass up hefty bills at the end of the month. However, a solar heater for greenhouse will immediately start saving you money as it does not have any running costs.
Uses Renewable Energy
The most alluring benefit of these heaters is that they get energy from the sun. Therefore, unlike natural gas, the sun is a renewable source of energy.
In addition to being inexpensive, the solar heaters are friendly to install too. You do not need to have a tight grip on science or technology to get it up and running. Mere know-how of how solar heaters work will get you through the process.
No Power Cuts
If you use electric or gas heaters for a greenhouse, you fear the power going out. However, a properly set-up solar heater will provide you with constant power. It also prevents your prize crop from getting destroyed in case of an extensive power outage.
Favorable to Environment
The sun is not only renewable but also a clean source of energy. This process does not produce harmful by-products or substances while heating the greenhouse. Therefore, you contribute towards a clean and green environment by reducing the carbon footprint.
