The benefits include:

Solar energy is inexhaustible, it cannot be produced too much, and it will always be enough for absolutely everything needed by mankind for many more generations.
- The amount of energy
The amount of energy from the Sun to the Earth annually comes about 1 billion terawatt-hours, while humanity produces about 20 thousand terawatt-hours per year, that is, 0.002% of the solar energy that comes to Earth.
The noiselessness of solar energy systems is achieved due to the fact that there are no moving parts in it, such as in a high-power wind turbine, where there is a rotor.
- Large area of use

This energy саn be used аs а heаting element, аs аn аuxiliаry equiрment tо inсreаse the рrоduсtiоn оf fresh wаter in the remоte settlements оf Egyрt, аnd оf соurse it is оne оf the mаin sоurсes оf energy fоr the Internаtiоnаl Sрасe Stаtiоn (ISS) аnd sаtellites, sinсe in sрасe the роwer оf sоlаr rаdiаtiоn is muсh higher thаn оn the surfасe оf the eаrth
- Economy of operation
By using solar panels as an alternative source of energy, building and private home owners can save a lot. A decisive factor in the area of service is that maintenance costs are very low. To maintain solar panels, you only need to clean them a few times a year, while the manufacturer’s warranty starts from 10 years.
Solar energy comes to those places where the sun shines, that is, absolutely to all parts of the planet, both to the equator and to northern latitudes, which makes it possible to extract solar energy everywhere.
- Advanced technology
Solar Projects EPC in Pakistan does not stand still. Every year there are more and more new developments from better materials, the efficiency of the solar panel is increasing, which allows solar panels to take up less space and generate more and more energy. Modern developments in the field of solar panel manufacturing technology will increase the efficiency in the foreseeable future up to 50%.
The disadvantages include the following:
- Great cost
This is a common reason for refusing to purchase solar panels, as they require a large initial investment and people cannot afford it. But in many developing countries, the government helps its citizens to purchase and install solar power plants, giving them loans and helping them complete all the necessary paperwork for this. In this area, Russia is very far behind, and therefore it is a problem for a large percentage of the population.
- Environmental pollution
As mentioned earlier, solar energy is the most environmentally friendly energy we see. But for its extraction it is necessary to produce solar panels, during the production of which greenhouse gases and chemical compounds are emitted into the atmosphere, which are dangerous for the environment and humans.
- Low power per square meter
One of the most important parameters of electricity is the average power density per square meter (m2), which is measured in W/m2, and the amount of energy that can be obtained per unit area.
For solar energy, this figure is on average 170 W / m2, this value is higher than that of all renewable energy sources used, but in comparison with traditional energy sources (oil, coal, gas, nuclear energy) this figure is much lower. Which leads to an increase in the area of solar panels for the production of 1 kW of energy.
- Intermittent cycle
The sun does not shine at night, and on cloudy days the amount of energy produced is significantly reduced, which in many cases makes solar energy not the main source of electricity. But even taking into account these factors, solar energy remains much more stable than, for example, also widespread wind energy.
- Problems of energy storage
Batteries are needed in this industry to store energy and periodically smooth out uneven energy from solar panels. Their main disadvantage is the price, since large-capacity batteries are quite expensive, and not every person can afford such a price. A partial solution to this problem is that the peak load occurs during daylight hours, where almost all the energy needed is generated by solar panels.
- Used elements
The manufacture of a Best Solar Companies in Pakistan requires materials that are rare earth, which increases their cost and makes them very difficult to manufacture and recycle. As a result, this leads to a significant increase in the price of solar panels.
