What is Solar Energy: All You Need To Know

With climate change in effect, the need for renewable energy sources is rising worldwide. Solar energy is one of the primary energy sources that can mitigate climate change by reducing greenhouse gas emissions and carbon footprints. If you are wondering what is solar energy and how does it work, the answer is: the use of photovoltaic solar panels to convert sunlight into electricity.

Solar energy can be used to power home appliances and RV equipment while saving significantly on power costs. When it comes to harnessing solar energy, a solar generator is an ideal choice. The Jackery Solar Generator can be an essential home backup that converts solar energy into electricity, powering most of your home appliances without relying on grid power. Read ahead to learn the uses, pros, cons, and common myths about solar energy.

Takeaways

• Solar energy is used to convert sunlight into electricity using photovoltaic (PV) panels. It can be used to power devices, start a steam turbine, etc.
• Solar energy is a renewable and consistent energy source. However, it has a high upfront cost, and installing solar panels on small houses can be challenging.
• There are five primary types of solar technologies: solar photovoltaic (PV) technology, passive solar technology, solar water heating, solar process heat, and concentrating solar power.
• The Jackery Solar Generator is ideal for powering essential home appliances, such as a water heater, microwave, and refrigerator, using solar energy.

What is Solar Energy?

Solar energy is defined as the conversion of sunlight to electricity or heat using solar technological equipment. PV or photovoltaic solar panels are the most commonly used solar technological equipment. Here is a more detailed process of how does solar energy work:

• When sunlight falls on the silicon PV solar panel, the panel's PV cells absorb the photons, which leads to the release of electrons from the silicon atoms, leading to increased electron speed.
• When these fast-moving electrons pass through the PV panel, they generate a direct current (DC) that flows into the conductive wire.
• The wire supplies the current to an inverter, which converts direct current (DC) to alternating current (AC). This AC is then fed directly to appliances.

If the energy is in excess, it can be stored in a solar energy storage system. If you search online for “what is solar energy storage system,” it will define it as a storage system that can accommodate excess solar energy, such as Li-ion batteries, for later use. As a homeowner, you can also feed the excess solar power to the grid to earn credit.

Applications of Solar Energy

There are several answers to the question “What is solar energy used for?” This is because it is an ideal and clean energy source. Here are some of the top applications or uses of solar energy:

1. Solar Water Heaters: Solar water heaters are an ideal application of solar energy, as the heated water can be used for bathing, laundry, and dishwashing. The setup includes a solar collector, insulated piping, and a hot water storage tank. Using an ENERGY STAR-certified solar water heater can reduce your annual hot water costs by up to half.
2. Powering Home Appliances: With the use of a solar generator, you can power most of your home appliances, including air conditioners, refrigerators, dishwashers, electric kettles, coffee makers, and other similar devices. The Jackery Solar Generator is a reliable home battery backup that can power appliances during outages or peak electricity hours.
3. Powering RV Equipment: Whether you're a full-time RVer or an occasional traveler, you can utilize RV solar panel kits to power your RV's essential equipment, including lights, stoves, outdoor grills, and mini refrigerators.
4. Charging Electric Vehicles: While the market for solar-powered motorcycles is still gaining momentum, solar energy may serve as an ideal way to power electric bikes and motorcycles.
5. Solar Lighting: You can save significantly on power bills by using solar energy to power your house’s interior and exterior lighting.

Advantages and Disadvantages of Solar Energy

Now that you know what is solar energy used for, find out what the advantages and disadvantages of solar energy are. Here are the pros and cons of solar energy:

How Different Solar Technologies Work

While the main definition of solar energy is well understood, there are different solar technologies where the process changes slightly. Here is an overview of various solar technologies.

Solar Photovoltaic Technology

Photovoltaic (PV) solar panels directly convert sunlight into electricity. This technology is utilized in various solar energy systems, including calculators, outdoor lights, and solar shingles.

Passive Solar Technology

Passive solar technology uses a combination of the sun’s heat, ventilation, and thermal mass components to heat and cool living spaces. Some crucial elements of a passive solar system include aperture, thermal mass, heat transfer method, and control (such as shading elements).

Solar Water Heating

Solar water heating utilizes solar panels to absorb solar radiation and transfer the heat to the water in the collector, which is then stored in an insulated tank for use. This is relatively more cost-saving than using grid power. 

Solar Process Heat

In addition to converting solar energy into electricity, solar process heat involves converting solar energy into heat for various industrial applications, such as food processing, the textile industry, and chemical production.

Concentrating Solar Power

Concentrating Solar Power (CSP) is a method that uses mirrors or lenses to converge sunlight onto a receiver, which converts it into heat. The generated heat energy is used to power a heat engine, such as a steam turbine, to generate electricity.

How Much Does Solar Energy Cost in 2026

Depending on multiple factors and your location in the United States, the average cost of a solar power system can be $25,000 to $40,000.

To run your household equipment on solar power, you need a comprehensive solar power system that includes solar panels, an inverter, racking equipment, wiring, and other necessary components. Additionally, there are various cost elements, including sales tax, installation charges, sales and marketing expenses, and overhead costs.

Note: These costs are estimates and are subject to change based on individual factors and the solar system's capacity.

Moreover, before choosing a solar system, you should conduct a solar energy cost comparison between portable systems and fixed installation systems.

Common Myths About Solar Energy (Debunked)

While there are some disadvantages to solar energy, certain myths and misconceptions have led people to overlook its benefits. Here are some common myths surrounding your question of what solar energy is, its cost, reliability, and lifespan.

Myth: Solar panels are too expensive to install

Yes, there is an upfront cost of installing solar panels. However, if you take advantage of government tax credits and rebates, you can offset a portion of this cost. Moreover, the overall power savings over the future years outweigh the cost of setting it up.

Myth: Solar is unreliable

Solar panels do not actively generate energy during nighttime. This is true, but there are solar energy storage solutions that store energy during the day and supply it to your appliances during nighttime.

Myth: Solar energy systems have a short lifespan.

The lifespan of solar energy systems can vary. However, according to the DOE, the estimated operational lifespan of a photovoltaic (PV) module is approximately 30 to 35 years. Some may even produce power for much longer.
