Driving hot: EVs, El Niño and that solar equation

On a quiet day last week, I sat in the driver’s seat of a Chevy Captiva EV.

It was Halloween week at the DAILY TRIBUNE, and as a theme, the folks in charge picked El Niño. There have been warnings upon warnings about the unbearable heat wave bound to hit the country sooner rather than later — or has it already? News reports confirm a strong El Niño active in the Tropical Pacific, intensifying into a very strong phase through late 2026 and the first half of 2027.

So, I guess we already know… it is so hot.

Back in the EV

I suppose that was what attracted me to take a seat in the Captiva EV. It offers a 100 percent pure electric driving experience. And then it hit me: the little surprises that come with getting into a modern electric vehicle (EV). Truth to tell, it took a little sleuthing just to figure out how to start the engine.

Funny, but each EV I’ve tried is filled with little secrets that one discovers as the driving experience begins. With the Captiva, there was no standard key and no obvious ignition point to spot. But with a little tinkering, I got the silent Captiva to start, and the drive began. Like all EVs, it ran whisper-quiet.

It got me thinking: back to El Niño, can the heat from the sun charge an EV and still allow our homes to stay lit and cool?

Direct heat from the sun itself does not charge the car. However, solar power can efficiently charge an EV in the Philippines. Instead of heat, solar panels installed on a home or building convert sunlight into electricity to power your electric vehicle.

How solar EV charging works

Rooftop solar panels: Photovoltaic panels capture sunlight and convert it into direct current electricity.

Inverters and chargers: An inverter converts that electricity into alternating current to feed into a home EV charger or standard outlet.

Daytime vs nighttime charging: Charging your EV directly while the sun is out during the day uses free solar power. If you charge at night, you either draw from a home solar battery storage system or pull power from the electric grid.

Environmental benefits

One of the most significant pros of EVs is their positive environmental impact. Unlike traditional gasoline-powered vehicles, EVs produce zero tailpipe emissions, helping reduce air pollution and the carbon footprint. By driving an EV, you contribute directly to a cleaner, greener environment, which is critical in cities facing traffic congestion and high pollution levels, such as Metro Manila.

Reduction in greenhouse gases: EVs help cut down CO2 emissions, a major contributor to climate change. Lower carbon footprint: They require less energy to operate, especially when charged with renewable sources like solar or wind power.

Lower operating costs

When it comes to day-to-day operations, electric vehicles are much cheaper to run than their gasoline counterparts:

Lower fuel costs: Charging an EV is significantly cheaper than refueling with gasoline, and home charging adds extra convenience and savings.

Lower maintenance costs: EVs have far fewer moving parts compared to internal combustion engine vehicles. With less wear and tear on components like engines, transmissions and exhaust systems, maintenance and repair bills drop drastically over the vehicle’s lifespan.

Quiet and smooth ride

One of the unique characteristics of EVs is the instant torque provided by electric motors. This translates into a smooth, responsive driving experience with quick, seamless acceleration — all paired with the peaceful quietness of an engine-free ride.

The cons and challenges:

Range anxiety

Despite significant improvements in battery technology, many electric vehicles still face the challenge of range anxiety (but that has to be blamed on the driver, right?). Most EVs can travel between 150 and 370 kilometers on a full charge, depending on the model. For drivers who often take long road trips or live in areas without widespread charging infrastructure, this can be an inconvenience — though expanding charging networks are gradually addressing the issue.

Charging times

Even though fast chargers are available, recharging an EV still takes significantly longer than filling up a gas tank.

Standard chargers: Standard chargers can take up to eight to 12 hours to fully charge an EV.

Fast chargers: Fast chargers can charge an EV up to 80 percent in about 30 minutes, but they are less common and more expensive.

Battery lifespan and replacement costs

EV batteries are designed to last for many years, but, like all batteries, they degrade over time. Eventually, you may need a replacement, which can be expensive — ranging anywhere from P60,000 to P300,000 or more, depending on the make and model.

Solar my life?

And if you have set up a solar system at home, just how much capacity do you need to charge the EV and keep your house running? A large calculator is definitely needed, because it all depends on the number of solar panels you have, how much you drive, and — given El Niño — just how intense the sun’s output is.

But all that is a story for another detour.
