Here’s What You Need To Know About 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. Since Trump has been increasingly interested in raising the tax, you have nothing to worry about as for 2018 and 2019, the tax credit is still in place.

  • Credit steps down –It’s important to understand that the value of the credit will go down as the year’s pass. In 2018 and 2019, the credit will remain 30%. In 2020, the tax will be 26% and in 2021, it will 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 on. 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 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 it 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. This includes all of the models that we’ve mentioned. 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 the fact that a hot and humid attic is detrimental fo your home. You are faced with high A/C bills, shorter shingle life, and mold/mildew issues. In the olden days, electric fans were the only option that you could use. The only problem with this solution is the fact that it had a heavy electric load that would cut into the savings that you tried to acquire.

Furthermore, the homeowners would’ve had to install a thermostat but that also had its own limitations. When the temperatures would rise, the fan would turn on. When the temperatures dropped, the fans turn off. The constant temperature fluctuations would damage the fan and it was often costly to repair. Nonetheless, no one can doubt the high capacity of air movement an electric fan would produce.

Take a look at each feature to decide which fan best suits your needs:

Solar Attic Fan
Electric Fan
Non-costly power bills Constant cooling ability
Low operational noise It’s not environmentally conscious
It can cover a large area Difficult DIY installation
Safe for the environment It requires maintenance
Easy to install by yourself Loud operational noise

Conclusion


These fans will take care of your needs and the environment. As we desperately need to save the planet, solar-powered fans are exactly what you need. After all, you will be exempt from city permits and other taxes, there’s nothing to lose by installing these products.
