Here’s What You Need To Know About the Solar Tax


In 2015, Congress has renewed the popular solar tax credit which allowed more homeowners to benefit from solar power. When you install a solar power system, the federal government rewards you with a tax credit for investing in solar energy. Thus, the money will be deducted from the amount of federal tax you owe each year just by having solar power.

  • Credit steps down – It’s important to understand that the value of the credit will go down as the years’ pass. In 2021, the tax is predicted to be 22%, whereas, in 2022, you will receive no credit if you don’t use it in commercial projects.
  • Easy to claim –There are numerous expenses that you can claim. Some of them are solar equipment, freight shipping costs, solar consulting fees, professional installer fees, electrician fees, engineer fees, and tools bought or rented. It’s important to understand that the cost will vary depending on the approach you take when it comes to installation.
  • There’s no middle man – Unlike electricity, you will be in charge of the system as you own everything. Therefore, you will have full control of how much the appliances can be powered with and when to turn them on or off. You don’t have to worry whether it will function at nighttime or in cloudy weather as the solar panels are innovatively designed to ensure maximum efficiency.
  • Money-saving – The bill states that if the motor doesn’t have a large capacity, you won’t have to pay tax. In other words, if your house runs on solar power, you will save a lot of money as you won’t have to pay the same taxes someone with unsustainable electricity does.

Effects of Solar Attic Fan Image

Solar Attic Fan vs Electric


There’s no hiding that a hot and humid attic is detrimental to your home. Some of the issues you will inevitably face if you don’t solve the issue regarding the conditions in the attic include high electricity bills, a shorter lifespan for the shingles, and mold/mildew. Back in the day, electric fans were the only viable solution to tame the high temperatures in the attic and solve some of the moisture-related problems caused by poor ventilation. Woefully, because of the way these models work, they imply higher running costs since the electric bills skyrocket.

On the other hand, we now have solar-powered fans that do the job just as fine if not better in some cases, depending on the model at hand. The extra perk you benefit from with these more Eco-friendly products is that there are no running costs involved whatsoever seeing how they draw their power from the sun.

Take a look at each aspect to decide which type best suits your needs:

Solar Attic Fan
Electric Fan
Running it doesn’t add a cent to the bills Draws a lot of electricity when it runs
Safe for the environment It’s not environmentally conscious
Provides uninterrupted cooling It won’t run when there’s a power outage
Its operation is almost inaudible Tends to get noisy when it runs
Easy DIY installation saves you money Difficult to install without professional help

Conclusion

Because these fans rely on solar power, they ventilate the space for which you install them without adding a cent to the electricity bills. Solar power is more Eco-friendly, cost-effective, and overall better option for both the consumer and the environment. Add to these perks the fact that you will be exempt from certain taxes, and you can see why more and more people opt for solar-powered products. Here, we reviewed and ranked the best fans at the moment to help you figure out what model best suits your situation, providing sufficient coverage to handle ventilation in your attic. Before we reach the inevitable end, we want to go over a few of the standout products once more to help you make up your mind.

Best solar attic fan for sale: Natural Light SAF36B-FL

This Natural Light model comes with all of the installation hardware needed and it’s fairly easy to set up so you don’t have to call a professional to help you with the process. What we like is that it comprises several standout features, including the fire safety switch that automatically turns the fan off when power surges are detected to prevent fire hazards. Moreover, the product is fitted with a DC motor that maintains quality over the years, ensuring that your money is spent as wisely as possible if you acquire it.

Editor’s choice: ESM Products 30w Solar Fan

Fairly priced considering the stats it flaunts which makes it vastly superior to its competitors, this ESM Products model was bound to catch our eye. It turns on automatically when the temperature reaches 80 degrees Fahrenheit to make sure that the attic won’t ever overheat again. Since it can cover spaces of up to 2,800 square feet, you can use it for ventilation in plenty of other areas, including warehouses, garages, barns, sheds, and more. Add to these perks the 25-year warranty for the housing and 5 years for the motor, and it’s clear as day why we favor it.

Best solar attic fan for shed: Solar RoofBlaster

Your primary option if you have a utility shed greenhouse, but just as appropriate for attics and garages, the RoofBlaster is a must-have as it provides up to 50,000 hours of operation, which makes it a smart investment from the get-go. If you run it 9 hours per day, this means that it will serve you for up to 15 years. Considering the asking price for the system, it’s safe to say this is a bargain. Woefully, it’s not that great in terms of coverage as it can only service areas of up to 100 square feet, but this is more than sufficient for sheds.

Best solar attic fan for the money: Amtrak Solar Fan

At the third of the price most models come at, you can have the Amtrak, which comes with a 50-watt panel and operates daily from the moment sunlight reaches it. Although it comes at a more than reasonable price, it doesn’t sacrifice durability or safety in use. It makes for an appealing option even for those who live in extremely hot areas as it features integrated protection to prevent unwanted incidents. When it comes to reliability, you can use it for spaces of up to 2,250 square feet, which makes it one of the most prolific fan systems in our top.
