The basic of solar energy

Have you ever think about how much energy the sun provides us every day? Continue reading and you’ll find out! Solar energy is renewable resource which means that they are replenished naturally and relatively quickly. So why doesn’t everything run on solar energy you ask? The answer isn’t simple, but I’ll try to explain it in my blog.

Solar energy in general

At its core, solar energy is radiant light and heat from the sun which is harnessed by us using various types of technologies. Solar energy can be converted directly into electricity or just used as heating of substances such as water.

Types of solar energy systems

I will deal with different types of solar systems in separated posts, but I`ll outline the basic types.

  1. Photovoltaic systems (PV): These system convert sunlight directly into electricity.
  2. Thermal systems: These systems capture heat emitted by the sun to heat or by generating steam to drive turbines and produce electricity.
  3. Concentrated solar power (CSP): Systems using mirrors or lenses to concentrate a large area of sunlight into small. Typically used to generate heat for electricity generation.

Benefits of using solar energy

  • Renewable: energy essentially inexhaustible on a human timescale
  • Environmentally friendly: produces minimal greenhouse gases and reduces reliance on fossil fuels
  • Low operating cost: solar panels require minimal maintenance and can significant reduce monthly bills
  • Versatile: Solar energy can be deployed on various scales, from small residential installations to large-scale utility projects

Challenges and considerations

  • Intermittency: Solar energy production is dependent on sunlight, so energy storage solutions or backup power sources may be needed for consistent electricity supply.
  • Initial Cost: While the long-term savings are significant, the upfront cost of installing solar panels can be a barrier for some individuals or businesses.
  • Land Use: Large-scale solar projects may require significant land area, leading to concerns about habitat disruption and land use conflicts.


Harnessing the power of the sun isn’t just about generating electricity; it’s about building a sustainable future for generations to come. By understanding the basics of solar energy and embracing its potential, we can move towards a cleaner, brighter tomorrow.

I look forward to our journey together to learn about solar energy.
