Utility-scale solar is dominating. Where's our savings?

As utilities continue to employ solar in order to save money, even over burning coal and natural gas, their rates to the end consumers continue to rise.

How to tame utility time-of-use plans with Airspool and Kasa

Although you can't always defeat utility time of use plans, you can at least tame them with the right tools--Airspool and Kasa.

Why is a mini split more efficient?

Minisplit air conditioners are more efficient since they i) don't have duct work ii) focus on cooling or heating only one room iii) often use super-efficient variable-speed compressors and fan motors.

UNLV Capstone project

Here's what we're working on with Dr. Greg Chmaj and his senior class as a potential Capstone Project.

The home of the future will be DC

Since so many of your appliances now run on DC power (computers, TVs, air conditioners (the good ones, anyway), and since solar creates DC power, it's beginning to make more sense to have one's home run on DC power. And, these guys from Purdue have created a model home to illustrate just that.

What is a 'solar ready' mini split?

What is a solar-ready or an ac/dc mini split? Quite simply, it's a mini split air conditioning heat pump that allows plug-in solar. The solar panel array just clicks onto the MC4 connectors on the outside unit. Cloudy or nighttime? These units are usually hybrid, so they also efficiently use grid power when not enough solar is available. Solar is always prioritized, though.

Yes, turn your air conditioner off if you're away (if it's not solar-powered)

Three engineers examined homes in hot dry AZ and hot humid GA on how to best manage the air conditioner when you're away from home. As expected?, the best savings came from turning it totally off if you work from work, especially if you have poor insulation.

Consumer Reports analyzes the Inflation Reduction Act's heat pump provision

Consumer points out that (albeit circuitously) that lots of folks won't qualify for any tax savings for buying a heat pump

Attn. Californians: Heat wave? Set your air conditioner colder and save money

California's grid operator and utilities are encouraging citizens to increase their energy savings by increasing the air temperature in their homes. Just say no! Get Airspool's (https://airspool.com/) solar-powered minisplit and set it to whatever temperature is most comfortable. It runs for free when it's sunny and very efficiently when grid power's needed.

Lots of folks in high-rate states like CA, MA, NH, VT, and ME still don't have air conditioners. Good solar air conditioner candidates.

The reasons can be debated, but the world, including areas that haven't had air conditioning in the past, are warming. Good candidates for solar-powered air conditioning.

Huge incentives for solar-powered heat pumps under the Inflation Reduction Act

Will it reduce inflation? That's debatable. But, there's a wave of huge free-money savings coming to anyone going solar or getting a heat pump--30% or more off.

Q: How often should my air conditioner run? A: Always, if it's efficient.

Traditional air conditioners are constantly turning on and off which i) isn't energy efficient, since their one-speed motors need 4-6 times more startup current than running current ii) wears down the motors, so they need more maintenance iii) create a larger temperature operating range, so users are less comfortable. Variable-speed motor, variable refrigerant flow (VRF) now efficient units run faster or slower depending on the heat load. Thus, they run slower, more efficiently with less motor wear and tear and with a tighter comfort range (deadband).

What the Inflation Reduction Act may mean to (solar-powered) heat pumps if passed

They have a deal! Biden, Schumer, and Manchin came up with something agreeable, and it's good news and big tax credits for the solar industry and (solar-powered) heat pumps. $369 billion for clean energy incentives.

What's solar augmented air conditioning?

By placing a smaller, more efficient solar-powered DC inverter air conditioner in the area of your home with the most demand, you can save a substantial amount of money at a much smaller cost than replacing your older system.

5 Factors Driving People Off-grid in the U.S. and How Solar-Powered Air Conditioning Helps

Utilities may not be shaking in their boots yet, but more and more individuals and families in the U.S. are building remote compounds to go off-grid for 5 primary reasons. Solar air conditioning fits in well for off-grid since motors are now primarily DC powered, the same power the solar panels create.

What's a hybrid solar DC air conditioner?

What's a hybrid solar DC air conditioner? Why did Airspool choose this technology to be the best value for those who want solar-powered air conditioning?

SEER vs. EER (and COP)

How exactly is EER calculated? How does it relate to COP? And, how can the COP of a unit be greater than 1, by the way? How exactly is SEER calculated? Why do we need SEER?

Why solar-powered air conditioners need more panel power on hot days

Spring/fall shoulder months greatly skew the SEER value of an air conditioner or heat pump's efficiency. But the pendulum really tilts in the other direction when it's 110 out.

Happy Summer Solstice

On the first day of summer, the day is long and hot. But with Airspool, at least your air conditioner's running for free.

Puerto Ricans take power management into their own hands

The government response to grid rebuilding in Puerto Rico has left much to be desired. But with solar+storage, citizens are end-running their public utility.

Wind and solar energy by hour for the continental USA

How does your state stack up for wind and solar availability?

How many solar panels are needed to run an air conditioner off-grid?

Airspool needs 3 solar panels, making it an outlier. Other normal air conditioners either need many more panels or they need a whole lotta batteries. Airspool needs not batteries, voltage regulators, net metering, or power inversion.

Don't be like Mr. Burns this Earth Day!

Net metering, slowly but surely, is going away, driving solar users to off-grid or hybrid

Is this a battle that's worth worrying about needing to fight in the future? Control your solar production and use it locally to heat and cool your home. Leverage the grid when it's cloudy or nighttime. State’s Department of Public Service recommends cuts to net metering rates https://vtdigger.org/2022/04/19/states-department-of-public-service-recommends-cuts-to-net-metering-rates/ via @vtdigger Net metering, slowly but surely, is going away.

More hurricanes? Airspool stays running even when the power's out after storms.

Solar-powered air conditioning units that are capable of running off-grid stay up and running, even when the grid and net-metered rooftop solar power is down.

Yes, solar is projected to save the world

Ember confirms that we can do this preventing future global warming thing. U.S. is still under 5% renewables, but we'll get there.

Why Solar is Heading for a Win

Q: What's carbon-neutral, and continues to get cheaper every year to use? (Hint: it's already cheaper than coal or natural gas, without even taking into account the sizable environmental impact of these fuels.) A: It's solar!

Where Solar-Powered Air Conditioning Works and Why That's Good News

In short, solar-powered air conditioning works where it's sunny, and that's good news since air conditioning units are forecasted to increase 250% by 2050, and since the greatest adoption in the coming years will be in the sunniest parts of our planet.

Hello World--Welcome to the Future of Air Conditioning

Solar-powered air conditioning was neither affordable nor viable in the past, since solar panel and electronic design technology wasn't where it is today. Now, 3 or 4 solar panels can run 12,000 BTUs of air conditioning. Cloudy or nighttime? No problem. Plug into 120v grid power for super-efficient 22-SEER cooling.
