Understanding Solar Energy
Solar energy is the conversion of the sun’s rays into usable energy. This form of energy is harnessed using a range of ever-evolving technologies like solar heating, solar thermal energy, solar photovoltaics, and many more. Solar energy is a renewable and clean source of energy, which reduces reliance on oil, coal, and natural gas for electricity production, which contribute to air and water pollution.
Basic Concepts of Solar Energy
At its core, solar energy works by converting light from the sun into electricity. This can be done through a process called photovoltaics. Photovoltaic cells in Solar panels absorb sunlight and through a physical and chemical process, they release electrons, which generate a flow of electricity.
Potential Benefits of Solar Energy
Solar energy comes with a multitude of benefits. It’s a clean, renewable source of energy, producing no greenhouse gases and needing no transport or supply pipelines. Solar panels, once installed, require little maintenance and produce energy quietly. Most importantly, they can result in significant energy savings over time, offsetting the initial installation cost.
Different Types of Solar Panels
There are primarily three types of solar panels: monocrystalline, polycrystalline, and thin-film panels. Each type comes with its own advantages and price points. Monocrystalline panels are the most efficient but also the most expensive, while thin-film panels are the least efficient but most affordable.
How Solar Panels Generate Electricity
Solar panels generate electricity through the photovoltaic effect. Sunlight hits the solar cells in the panel, and electrons are knocked loose from their atoms. When these electrons flow, they create electricity, which can be captured, converted, and used to power electric loads.

Assessing Your Home’s Solar Potential
Before installing a solar panel, it is important to assess your home’s solar potential. Not every roof has the proper orientation or angle for solar panels, and the amount of sunlight your home receives may also vary.
Checking Roof’s Direction and Angle
The roof’s direction or orientation affects the amount of sunlight your solar panels will receive. In general, solar panels produce the most electricity when they’re facing south. The roof’s angle or tilt also matters. A 30-degree angle is considered ideal, but anywhere between 15 to 40 degrees can work.
