In the summer, houses can get incredibly hot. Especially if your house does not have any trees around to provide some shade. That is because it sits directly in the sun, obviously. People have discovered various ways to prevent over-heating, but very few solutions provide truly efficient results. So what choice do you have?
Most houses in areas where summers are harsh are equipped with air conditioning systems. It’s the obvious solution, but when it’s too hot outside, these systems work overtime to bring the temperatures down. Do you know why that is? Because everybody wants their house cool, but almost nobody ever thinks to tackle the primary cause of overheating, which is the attic temperature.
During sunny days, the roof gets what’s worse of the outside temperature. Of course, it matters what the roof is made of, but no matter what material you choose, it will still get pretty hot. That transforms your attic into an oven. The air temperature can get so high up there, that you can’t even stand to go in your attic for five minutes. What is the best solution?
Solar attic fans are the way to go. They will bring down the temperature in your attic, so none of the high temperatures reaches the ground level(s). I think it’s a brilliant idea. Not only that your house will have a more than bearable temperature, but your power bill will also be lower.
You can always go for an attic fan that is driven by your house’s power system, but then what’s the point? Your purpose is to save money, not to waste them. After all, all those burning sun rays must make themselves useful. That’s why is better to go solar. Here are the primary benefits.
If you take a look at the offer, you will see that there are hundreds of models of solar attic fans, each with its own advantages and disadvantages. But here is what you need to consider to make an informed purchase.
Since the solar attic fan will only work while the sun is up, it will only work during the day, clearly. But there is a trick to change that. A lot of people do this. During the day the panel collects more energy than it needs to engage the fan. That is why it is recommended to buy an energy storage unit (battery). During the day, the sun will power the fan, but it will also fill the battery. And just like that, your attic fan will work during the night as well.
Browsing through what’s on the market can drive you crazy. There are some many. So how can you decide which is the best solar attic fan? Just look for the criteria I mentioned earlier and filter through. Here are three examples.
Natural Light is a leading company in solar energy powered products. They reached the top by providing high-quality, reliable products. Which is probably why this unit comes with a 25-year warranty. And not only for the fan, or just the solar panel, but the entire unit.
Once you get a hold of the attic fan, you can notice that it is made of superior quality materials. Few brands provide this sturdiness. It is very easy to install. It doesn’t require specialized knowledge. As long as you are good with your hands and are familiar with a bit of DIY, you should be able to complete the installation by yourself. There is no extra wiring. What you see is what you get. All the hardware you need for the setup will be provided for you.
You have the possibility of acquiring an optional snap-on thermostat. But that is recommended for cold locations. When it’s sunny and hot all year-round, you don’t really need it. The choice is yours.
Let’s get technical. This solar attic fan will be able to cool down an attic with a surface of up to 2625 square feet. Make the necessary measurements, and if your attic exceeds this surface, the manufacturer advises that you buy two such attic fans. There is no point in trying to make it work with just one. The fan has been tested, and 2625 is as high as it can get. The fan can move up to 1628 cubic feet per minute.
The DC motor is powered by a 36-watt solar panel. The panel is adjustable, from flat to a 45-degree angle. You can even detach and mount it in a place where there is a better sun exposure. However, this solar attic fan is not to be installed on a flat roof or mounted on side walls. As long as you use it as you’re supposed to, you will be very satisfied with it.
As a bonus, a part of the investment qualifies for tax credits in the Solar Energy Systems category under Photovoltaic Systems as defined in the Energy Improvement and Extension Act of 2008. Also, you may be eligible forlocalcredits. Click here to read more reviews and buy on Amazon.
The Brightwattsunit comes with an only a10-year warranty, but that does not mean the quality is inferior. Quite the contrary, the Brushless DC motor is built to last. The construction is sturdy, and the galvanized steel that it’s made of is rust protected. You will enjoy it for quite some time.
Unlike the previous attic fan, this one can handle to cool down a surface up to 1250 square feet, and the fan can move up to 1000 cubic feet per minute. Apparently, it is designed for smaller attics, but I find it to be a good thing. Not everyone has a 2500 sq ft attic. What are you supposed to do? Buy a much too big fan for half the space it can actually handle? That’s just bad investment.
You should know that the motor is protected against overheating, which I believe it’s necessary. The fan is cooling down the attic, but what is cooling down the fan? It is very easy to install, you don’t need to do extra wiring.
The panel is made of high-quality polycrystalline cells. It will resist hail, ice, and even flying debris and impact winds. It produces 12.6 watts, just enough to keep the fan going all day long. You can even add another panel if you see fit. What I liked about this solar attic fan is that it comes with a built-in thermostat, which may prove to be very useful to people who live in colder regions.

I’ve been looking at solar attic fans for a few days now, and honestly, it’s pretty difficult to top Natural Light products. Everywhere I looked, people only had nice words to say about them. No faults, easy installation, and the ventilation control is as efficient as advertised. And then I said to myself, why not recommend the same product? It’s not the very same, obviously. But people with smaller attics should be able to enjoy the quality that only Natural Lights can provide.
Basically, we are talking about the same product as the first, but this one is designed for smaller spaces. It can properly ventilate an attic with a surface up to 2100 square feet, and the fan moves up to 1339 cubic feet per minute. The panel can only provide 24 watts, as opposed to the bigger one which can provide 36. It fits all roof types, except the flat ones. Click here to read more reviews and buy on Amazon.
I think you can guess what my choice is. I would go for the Natural Lights Solar Attic Fan every day of the week. Whichever of the two. The fact that it can be installed on almost rooftops, the easy installation, no extra wiring, the federal tax perks, and the power of this unit make it the best solar attic fan on the market.
So, if your attic gets very hot during those scorching summer days, then a solar attic fan is precisely what you need. It will keep the attic temperatures down, it protects against mold and moisture, it will give a break to your AC unit downstairs, and last, but certainly not least, will lower your power bill. From where I stand, you only have to gain from making such an investment. Click here to buy on Amazon
