What Is Solar Energy?

What Is Solar Energy?

Most people understand the basics of solar energy and how panels utilize rays from the sun to generate energy, but that’s an extremely simplified definition. So how does solar energy work really?

How Do Solar Panels Work?

By utilizing the power of the sun, solar energy is an incredible way to help the environment while saving you thousands of dollars. Solar power is harnessed through photovoltaic (PV) cell technology – panels that convert sunlight directly into electricity. For those not proficient in solar panels or the “photovoltaic effect,” when the sunshine is absorbed by a PV cell, the photons of light excite the electrons in the cell, causing them to flow and generate electricity. 

Homeowners, business owners, and agricultural experts from around the world are installing solar panel systems on their roofs to maximize the use of this clean, renewable method to generate power. Residents of Nebraska can join in on solar power’s benefits by contacting our team at J-Tech Construction & Solar. Sign up for a free solar estimate today.

Solar Power Benefits

Good for Our Environment

Unlike conventional power, solar energy produces zero harmful emissions that hurt the environment. Solar energy uses a clean and renewable process that uses an infinite resource and is harmless to wildlife.

Alternative to Fossil Fuels

In America alone, fossil fuels are used to generate an overwhelming 68% of the electricity we consume. As a result, the emissions generated from the combustion of these fossil fuels are incredibly harmful to our planet. Solar panels generate no emissions at all and last for decades.

Save Thousands in Energy Bills

By living “off the grid,” you are not only doing your part to help the environment, but you and your family will save thousands of dollars in energy costs.

Solar Power Basics

Solar panels are an incredible technology that has allowed us to not only increase the efficiency of our power consumption, but also care for our planet.In 2020, over 3 million homes were powered by solar energy and with the solar tax credits available, the number of solar powered homes will only increase. But how does it work? Watch the short TED-eD video to learn more!

Fast Growing

Solar has ranked either first or second in capacity added to the U.S. electric total every year since 2013. It goes to show that solar energy really works.

70% Price Decrease

Since 2014, the average cost of solar PV panels has dropped nearly 70%. New solar panel owners can also redeem federal tax incentives that can help save even more.

20 Panels

The average U.S. residential solar installation is about 5KW, or around 20 panels. Our team will help you calculate the appropriate number.

Frequently Asked Questions


The basics of solar energy revolve around energy transfer from the sun to the panels spread across your property. Solar panels are made with silicon that is melted and mixed with a couple other metals to produce a silicon ingot. An anti-reflective coating and conductive lines are then added to the panel. Now the semiconductor will absorb sunlight and create an electric current.


As solar energy technology continues to evolve, many of the drawbacks of solar energy are being mitigated. Solar panels used to have high initial costs, but they are much less expensive than they were only 10 years ago, and are quicker to provide a return on investment. They used to also be exceedingly large, but modern solar panels are much lighter and manageable.


While there are a wide variety of solar panels that can be implemented onto your roof, not all roofs are panel compatible. Our team at J-Tech Solar will help determine if solar panels should be added to your roof or if there is another location on the ground floor that will provide even greater benefits.

How Much Power Does a Solar Panel Produce?

Depending on their efficiency, wattage rating, and exposure to sunlight, the amount of energy that a panel will produce tends to fluctuate from day to day. On average, solar panels can produce anywhere from 1.5 to 2 kilowatt-hours (kWh) of energy per day.

What is the Efficiency of Solar Panels?

Solar panel efficiency is calculated based on how much sunlight is converted into electricity and how much of it is reflected off. Most solar panels that are available to the general public have an efficiency rating between 15% and 25%. Higher efficiency panels tend to be more expensive because of their materials and manufacturing processes.
