Solar energy is characterize by many things as follows: sustainability: solar energy is the ideal alternative to fossil fuel products, including oil, gas, and coal, as these sources are nearing completion, and solar energy is inaccessible because it is dependent on sunlight, which expects to continue to glow for billions of years.
Environmentally friendly: the technology used in solar energy production has little impact on the surrounding environment than fossil fuels, i.e., it is safe and clean energy for all living organisms.
Self-sufficiency in energy production: solar energy provides independence in international energy production, and the sun radiates to all nations. Conservation of water resources: solar power generation does not require water consumption or pollution, unlike fossil fuels and nuclear power plants that consume or pollute much water.
renewable technologies reduce renewable energy costs as much as possible so that they become highly competitive against other traditional energy types, thus affecting solar energy on the global economic side.
solar energy has provided many local employment opportunities, providing them everywhere globally, not limited to a particular environment. These were public benefits and advantages of solar energy, but what about its advantages for homes? Here are some points that answer this question.
The process of installing solar panel cells at first is relatively expensive, but saving money is very large in the long run, contributing to the generation of electricity for the individual and leading to the eventual disappearance of electricity bills.
Solar energy is given autonomy in generating electricity, storing it when needs and the power remains in the house even if there is a power outage. Lack of maintenance: solar equipment does not require expensive periodic maintenance, with little supervision required.
Other advantages: solar panels in homes increase their physical value, how much they give a sense of comfort to a person after learning that it contributes to the suspension of the environment and the globe.
Solar Defects Despite The Many Advantages Of Solar Energy.
There are many significant drawbacks to it. Solar energy is based on sunlight that shines during the day, and the amount of energy collected by solar panels varies depending on seasons and time differences throughout the day.
The quality of solar panels in converting solar energy into electricity is not high and only reaches 20% despite its high cost.
The lower the efficiency of solar energy by region, the further away from the equator towards the poles. Less solar energy can assemble, for example, Russia and Canada suffer from a significant shortage of solar energy.
They reduce solar energy collection capacity when clouds, fog, and rain are present. They are installing solar panels outside and constantly exposing them to sunlight, which may further damage them due to external conditions like rain, snow, dirt, dust, wind. And different temperatures.
How To Get Electricity From Solar Energy
the amount of energy falling on earth from the sun for only an hour and a half is equivalent to the total energy consumed by humans for a whole year.
From this point of view, the search for ways to take advantage of this energy may make sense. And what science has come to is to convert it into electricity through PV cells; the mechanism for converting it into electricity is as follows:
THE SOLAR PANEL MATRIX IS INSTALLED ON ROOFTOPS OR IN LARGE OUTDOOR AREAS. THE PANELS CONSIST OF PHOTOVOLTAIC CELLS (PV) THAT ABSORB SOLAR RADIATION DURING THE DAY.
Each solar cell contains chips from semiconductors made of two silicon layers, one positive and the other negative. And forming an electrical field.
It absorbed by these cells contributes to its activation by causing the movement of electrons between the two layers. This movement contributes to the generation of electricity.
IT FORMS A DC CONTINUOUS ELECTRICAL CURRENT, WHICH IS NOT USE IN THE OPERATION OF HOMES. SO IT MUST CONVERT FROM A CONTINUOUS CURRENT TO AN AC USING SMALL TRANSFORMERS INSTALLED BEHIND SOLAR PANELS.
After the production of ac power, this current distributes inside the house through its power panel to operate all electrical appliances. Store excess energy collected during the day, take advantage of it at night and on rainy days, and cloudy. And we can store in batteries or stored thermally.
Tips For Taking Advantage Of Solar Energy
Suppose solar cells are placed above the roof of the house. In that case, some things recommend to be taken into account to maximize energy utilization and maintain their durability. Including avoiding washing solar panels with cold water that may crack and damage cells. The storage battery should save the excess energy generated while choosing a good quality and searching for cheap types.
Some batteries consider toxic and dangerous if damaged. Ensure that the solar panels place at the right required angle to the kind of panel used. And calibrated at least every three months to maintain performance.
Be aware that there is no barrier to sunlight reaching panels, such as trees or power poles.
Keep clean the surfaces of solar panels and wash them weekly during the night hours. To maintain the quality of their absorption of solar radiation.
When you hear any sound from the current adapter, it must turn off or closed directly without hesitation. Avoid using batteries of different sizes and types and connect them. Avoid placing batteries in a dark, hot, or low-ventilation place.
