The Sun is the source of life all over the globe, and solar power is beneficial to us in several forms.
The Sun generates two main energy types–light and heat–for many activities, from plant photosynthesis to electricity generation using photovoltaic (PV) cells and water and food supplies.
So, people often wonder about some solar energy uses? Why is solar power good? The rise of renewable energy is Solar Power. Consider seven benefits and advantages of solar energy in our everyday lives.
Most homeowners do not know that solar and solar water heaters are an economical way to heat their own homes without investing in the construction of solar panels.
Solar water heaters harness and convert sunlight into thermal energy using fluid or air, while solar water heaters use water as a method in the process of thermal transmission.
Such solar heaters can be passive, or active-while passive systems use natural circulation active systems to use water pumps to generate heat.
Householders who build a thermal solar panel on their roofs can expect between 5 and 10% of the returns with a device that costs a fraction of the entire solar panel facility.
The potential to heat the pool more effectively than conventional solutions such as oil and gas pumps is a major advantage of solar thermal energy.
According to the United States Energy Department, “The most cost-effective use of solar power is solar pool heating in many climates.” The technology uses, in its most simple way, a solar collector to harness and turn sunlight into heat.
To heat the pool, water is then drawn by the collector. It can also be used at night to cool water (usually only in hotter climates).
Photovoltaic (PV) devices consist of one or more solar panels in conjunction with electrical and mechanical equipment and inverter utilizing Sun’s energy to produce electrical power.
PV systems can vary considerably between tiny rooftops or portable systems and massive power generating plants.
The Sun’s light, made up of energy packets known as photons, falls on a solar panel generating an electric current through the photovoltaic effect.
Each panel emits very little energy but can be connected to other panels to produce higher energy levels as a solar panel. The generated electricity is in direct current (CC) form from the solar panel (or array).
Even if many electronic devices use DC, like your phone or laptop, the electrical grid which supplies (and requires) alternating current (AC) is intended to operate on them. In solar energy to be efficient, it must, therefore, be used.
So it must first be switched from DC to AC by an inverter to make solar electricity usable. Such AC energy can then be used by the inverter to power electronics locally or transferred to the grid to another place.
Solar ventilation air preheating (solar ventilation preheat) technology with a transpired solar collector is one of the most simple, cost-effective, more reliable, and high-performance applications of solar heating.
Due to the simplicity of the technology, the maintenance requirements are minimal.
The major parameters include the wall area, airflow rate, hole spacing, and solar absorptance of a material.
The transpired collector is fixed about 6” (inches) away from the south-facing wall (recommended +/- 20° of the south as the best for heat delivery around 96%–100%). The wall should necessarily be made about four feet wide and length of perforated metal panels.
With tiny holes about 1mm in diameter, the collector is coated and painted in a dark to medium colors to absorb maximum radiation.
Solar lamps have become omnipresent and can be seen everywhere, from home and security lighting to road signs and street lights. Such solar lighting systems are cost-effective and readily available in both standard and high-end projects.
Solar-powered vehicles such as buses, trains, flights, and race cars are designed with existing applications by students of the United States and Australia. Perhaps shortly, we can see the commercial release of a completely solar-powered vehicle.
Renewable energy is becoming more familiar, and innovation will continue to encourage new uses of solar technology that improve our daily lives and help to power a cleaner world.
How many more applications will there be of solar power in the future? We’re looking forward to hearing more new solar energy uses!
