Fundamentals of Solar Power

Solar power is one of the most potent sources of renewable energy on earth. Its benefits include low cost, flexibility, and the ability to create jobs and economic development.

However, it does require a significant initial investment and can be more expensive than traditional grid-based electricity. That said, many grants and rebates help make it more affordable for some homeowners.

Solar Energy

Solar energy harnesses the sun’s natural radiation to create electricity, which shows average cost of solar panels in texas. It can power homes, businesses, farms, and immense power stations.

The sun is our planet’s primary source of energy. It produces over 500 million tons of hydrogen atoms each second, resulting in the constant nuclear fusion reaction that generates solar power.

Using solar energy is a great way to lessen our dependence on fossil fuels, which are the leading cause of climate change. Fossil fuels also pollute the air and water and contribute to ozone depletion.

When the sun’s rays strike solar cells, called photovoltaic (PV) cells, they knock electrons off the atoms in silicon and generate electricity. This is then transferred to an inverter that changes the DC electricity into AC electricity, which homes use to create light, heat, and power appliances.

Photovoltaic (PV)

Solar power is the process of converting energy from sunlight into electricity. This can happen in several ways, but the most common way is using photovoltaic cells.

PV cells are made of semiconductor materials that can absorb light and transfer energy to negatively charged particles called electrons. These electrons flow from the front of a cell to the back and through an electrical connector, like a wire.

The amount of electricity that can be generated depends on the efficiency of the cell, the average annual sunshine in a region, and the type of installation. This can vary from a few hundred watts in Paris to hundreds of MWh/year in the desert Southwest.

Concentrating Solar-Thermal (CSP)

Concentrated solar-thermal (CSP) power is a clean and reliable alternative to conventional coal or gas-fired power. It focuses the sun’s energy on a thermal engine that drives an electricity-generating turbine or steam turbine.

In addition to generating electricity, CSP systems can also store heat to produce electrical energy during peak demand. This can be achieved through various methods, including sensible heat storage, latent heat storage using phase change materials (PCMs), or thermochemical storage.

The environmental impact of CSP is significantly reduced compared to fossil fuels. This is primarily because carbon dioxide emissions are reduced considerably when a CSP plant replaces a coal or natural gas-fired power plant.


Solar power can be stored in various ways, including batteries and heat storage. However, most residential systems use battery energy storage.

Most people buy batteries because they want to save money on utility bills by storing excess energy produced by their solar panels during peak demand hours when electricity rates are highest. They also want to reduce their reliance on the electric grid in case of power outages.

The combination of solar and storage is a win-win, as both technologies allow for more renewable energy and electricity self-sufficiency. But before deciding which type of storage is best for your project, it is essential to understand your facility’s needs and capacity.
