## Overview

The Spartan Sol Solar Ventilation Fan is a compact, weather-resistant exhaust fan designed to fit universally on 3" and 4" PVC/ABS pipes. Powered by a 2.7-watt solar panel, it delivers 40 CFM of airflow with a quiet 40 dB operation and a lifespan exceeding 40,000 hours. Perfect for enhancing airflow in portable restrooms, sheds, dog houses, and greenhouses, this fan requires direct sunlight and offers an eco-friendly, maintenance-free ventilation solution.

## Description

*Direct sun exposure required* The Johhny Hat is a solar powered ventilation fan that has been designed to fit inside 4" PVC/ABS and over the top of 3'' PVC/ABS. Because of this, it can be used for almost any application! Without any additional parts the Johhny Hat can be mounted to nearly any portable restroom, added to existing vents on other structures. With some plumbing parts it can be easily adapted to be used on dog houses, sheds, green houses, and a variety of holding tanks. With standard PVC or ABS parts you easily change the mounting angles or even add multiple fixtures together for larger areas. Unlike other solar powered fans, we have embraced the square/rectangle shape of solar panel cells. Because of this, we are able to capture 2-4 times the amount of solar power to have a more useable and reliable ventilation fan for whatever structure, room or holding tank you are trying to keep cool and odor free. *Solar powered products require direct sun exposure* This product DOES NOT have battery backup

Review: Easy to install - Works great use it in my duck coop, works wonderfully!!
Review: Great little solar fan - Purchased to help eliminate heat in large shed. Vented through side initially, however this fan requires full direct Sun to work, so it only worked intermittently. Remounted with ducting so it faces straight up, and now it works almost all day long eliminating the heat. Not sure how much air it moves, but it’s enough for a large shed.

### ⭐⭐⭐ Good but......
*by P***Y on January 19, 2026*

It looks well-made; however, there are some issues with the solar fan. First, you MUST have in Direct sunlight, will not work with any shade whatsoever. Second, there is no battery bank so, when the Direct sunlight is gone, it stops working all together. I was going to add a battery bank but, there is no way to disassemble the Vent to wire a battery bank in.
