My greenhouse size dictated the fan’s capacity; a bigger space requires a fan with higher CFM to properly ventilate. It’s important to calculate your greenhouse volume and choose a fan that can handle the air exchange rate needed for your plants. Installation and Maintenance I looked for models that were easy to install without professional help. Most solar fans come with mounting kits and clear instructions, but I also considered how easy it would be to clean the fan blades and solar panel. Regular maintenance ensures the fan runs efficiently over time. Additional Features to Consider Some fans offer thermostat controls or automatic on/off functions, which I found convenient because they adjust ventilation based on temperature changes. Noise level was another factor; a quieter fan keeps the greenhouse environment peaceful. Budget and Warranty Setting a budget helped me narrow down options. While I didn’t want to compromise on quality, I also looked for fans that offered warranties, as this gave me peace of mind about the product’s durability and performance.
