I decided to install solar panels on my car for energy independence. And I also wanted to avoid ever having a flat battery again.
The sun, the source of all life on Earth, provides abundant energy that we can harness and store. Solar power systems work similarly whether they’re on a house or a car. Each system involves several components working together in harmony.
But the sun’s power has its limitations. Factors like our atmosphere, the angle of the Earth, and weather can affect sunlight’s availability. Even the most efficient photovoltaic cells have limits to how much energy they can capture in real-world conditions. Consider also the placement of your panels in relation to obstructions like trees or buildings. Debris such as bird droppings and leaves can also reduce potential power generation.
While the choices for solar panel systems might seem overwhelming, achieving true energy independence is worth it. Whether you’re installing panels on your home or car, you’ll face similar decisions regarding panel placement, orientation, and how each component interacts within the system.
Solar panels on a home may have fewer debris issues, but they could be harder to reach for cleaning. In either case, anything blocking the sun’s rays will reduce energy production.
After panel installation, the next component in the system is the charge controller. It collects the raw DC current from the solar panels and directs it further into the system. The charge controller also prevents electricity backflow, which can damage the system. Think of a parabola: the charge controller keeps the power flowing forward.
In my car’s solar system, the next stop is the battery. I use my car’s battery, but I also have a secondary battery to which I can switch as needed. It’s important to have a battery installed before connecting the charge controller to the solar panels. Otherwise, the unregulated energy from the panels could damage the charge controller.
To use the stored DC energy for household appliances, you’ll need an inverter. It converts DC energy into AC energy, which is what household appliances require. Home solar systems use inverters for the same purpose, but they also involve additional components like circuit panel integration and connections to the power grid.
While the sun shines only a few hours each day, those hours can provide plenty of energy to store or use directly. Solar technology continues to improve, and its potential to transform how we generate and use energy is enormous.
Did you know? -> The State of Washington will Pay Sales Tax on your solar panels1
ON TOP OF THAT -> A solar investment tax credit (ITC)2 reduces taxes normally due the federal government.
