How Did We Rank The Best Greenhouse Solar Heaters Of 2023?

When it comes to ranking the best greenhouse solar heaters of 2023, there are several factors that we consider to ensure that we provide accurate and reliable information. Here’s a breakdown of how we rank these heaters:

Greenhouse Size

The size of the greenhouse plays a crucial role in determining the type and size of solar panels needed for the heater. Larger greenhouses require more robust panels to effectively heat the space, while smaller greenhouses can make do with smaller panels.

We take into account the square footage of the greenhouse to determine the appropriate solar panel wattage.

Plants Inside the Greenhouse

Different plants have different temperature requirements. We consider the type of plants that are typically grown in greenhouses and how much heat they require.

For example, crops like tomatoes often need more heat in the winter, so a smaller heater may not be sufficient. We evaluated the specific temperature needs of various plants to ensure that the recommended solar heaters can adequately meet those requirements.

Level of Insulation

We took into account the insulation quality of the greenhouse to determine the appropriate panel size.

HandyControls in the Panels

To make the solar panels more user-friendly, we considered the presence of handy controls such as temperature sensors, mounting brackets, and controllers for overcharging. These features allow users to regulate the panels more easily and enhance their functionality and reliability.

Ease of Installation

We also evaluated whether the panel offers easy and direct mounting options. Additionally, we take into account the versatility of installation, such as the ability to mount the panels on a boat, cabin, or rough surface.


Budget plays a significant role in the decision-making process. We took into consideration those solar heaters that were cost-effective, even if they were on the pricier spectrum.


How To Heat A Greenhouse With Solar Panels?

Here’s a step-by-step guide on how to use a solar heater in a greenhouse:

Step 1: Install Support Structures

Install support structures after planning solar panel placement. Handles, locks, and brackets may be used to secure the panels to the roof or other support structures. Make sure the support structures can hold the panels.

Step 2: Connect Wires

Solar heaters need proper wiring. Connect all panels and waterproof and insulate cables. Safety comes foremost, therefore connect the grounded fasteners to the ground wire first to avoid electrocution.

Step 3: Install Solar Panels

After wiring, install the solar panels. Securely fasten and slant them for maximum sunlight. Tilt the panels to maximize sunlight absorption.

Step 4: Connect Inverter and PV Components

Connecting the inverter to the greenhouse’s AC circuit breaker panel completes the process. Connect the PV system and circuit breaker to the PV lines. Connect the inverter to the DC main breaker last. Solar heater installation is complete.
