Solar energy – the way forward

Solar power


For a long time, solar energy was only identified as the conversion of sunlight into electricity. While this is not inaccurate, most of us do not know that the energy harvested must first be converted into electrical energy in order to produce generally functional electricity. The conversion is made possible through solar cells or solar cells, a method that uses semiconductors to convert solar radiation into electrical energy.

Components of a simple solar energy system

Solar cells or solar cells

The assembly of semiconductors and electronics or solar cells is enclosed in a solar cell module, more commonly known as a solar panel. Multiple solar panels are called solar panel array.


A solar panel collects and generates energy from the sun’s radiation. PV panels convert this energy into direct current, a current produced by batteries. Although it is possible to connect a DC load directly to the solar panel, batteries play an important role for a properly functioning photovoltaic system.


A regulator is optional, but still an important equipment in a photovoltaic system. During the cyclic process, the battery is likely to become overcharged or overcharged, a situation that shortens the life of the batteries. A regulator prevents such situations from happening by regulating the condition of the batteries. It maintains a charging stage where it monitors when the battery will be overcharged or discharged. In general, a regulator keeps the batteries under the most suitable working conditions.

Convert / inverter

A converter makes it possible to convert direct current stored in the batteries to alternating current or alternating current, the type of energy used by the power supply. DC / AC or direct / alternating converter is also called an inverter and is used to match the required current and voltage after the load. It is typical to experience some energy loss during electrical conversion.


All appliances that use power are considered a load. When choosing a load for the solar system, it is necessary to start with a low power component before installing additional solar panels to avoid wasting resources. Solar cell systems are ideal for lighting, as light only consumes more watts compared to larger appliances such as televisions, components or computers. There is also lighting that works on direct current, making it possible to use solar energy system on a low budget scale.

Solar panels, battery, regulator, converter and load make up the solar panel system. When all these components are installed correctly, a solar energy system can sustain itself for years.

Benefits of solar energy

For most private users, the electricity grid is the most convenient source of electricity. It seems that there is still a huge power outage or power outage in the distant future. However, the growing concern about the depletion of fossil fuels is attracting authorities around the world to exploit renewable energy sources. Since solar energy is the most commercial among other renewable energies, it is necessary to know how you as an end user of homes can benefit from solar energy.

Low cost production

Solar energy is a documented commercial energy source. Among other renewable resources such as wind, hydropower, biomass, biofuels and geothermal energy, solar installations Johannesburg energy is the only clean energy capable of generating a large market scale including private users. Due to advances in solar technology and the consistent improvement of financing methods, the implementation of solar energy projects is steadily declining.

China’s emergence as one of the largest manufacturers of solar panels greatly affects the price of end – user materials. The country also produces wind turbines, although exports are limited in contrast to global production and exports of photovoltaic systems.

Infinite source of energy

Depletion of fossil fuels is a disparate threat to energy security. Fossil fuels are non-renewable energy sources and their exhaustion is inevitable, meaning a lack of power supply worldwide. On the other hand, renewable energy such as solar energy, wind and geothermal energy are able to generate electricity without breaking down natural resources. These natural energies are infinite sources of energy. If installed and used correctly and strategically, renewable energy can supply the world with clean electricity.
