Solar energy about to become an indispensable energy is really coveted today thanks to its ecological and economic benefits. However, despite its many benefits, it also has drawbacks.

unparalleled source of energy

Why solar power?

Renewable and inexhaustible energy, solar energy provides free heating and hot water of a house by installing photovoltaic panels or solar thermal power plants.

This solution thus reduces transportation costs of the current. The size of the flexible facilities can easily adapt to the needs of each household.

This type of energy also contributes greatly to the preservation of the environment. This is a pure energy, non-polluting.

The installation of a solar system is particularly cost-effective in countries or regions that do not have electrical installations networks. You simply connect the solar system to the electricity distributor network.

This solar system can also be installed on the roofs of individual homes or on roofs of buildings.

How to make a solar system?

A photovoltaic system requires three elements, namely:

. Of solar panels

. An inverter

. And a counter

With these elements, it is possible to recover energy from the sun, convert it into electrical energy and distribute:

. On the roof, solar panels convert light into electric current permanent.

. UPS on its side will convert electricity obtained by suitable AC network.

. The counter meanwhile measuring the volume flow fed into the network.

Economic Benefits

For a domestic installation using solar energy, repayment of the price of the installation is up to 60% in France thanks to the grant from the state.

Investing for solar panels is interesting for individuals.

The amortization of the investment lasts 8 to 10 years, but this period may be shortened if lower needs.

Apart from their initial price, the use of these panels allows to benefit from a free energy for 30 years.

In case of solar energy would be used only for domestic heating and water heating, facility prices are affordable.

With the advent of technology, the price of solar panels experiencing a palpable decline while their performance has improved a lot. The price of silicon has also decreased significantly for some time due to its overproduction.

Environmental Benefits

In contrast to other fossil fuels, such as oil, coal, and uranium which are depleted over time, solar energy is for its renewable and inexhaustible.

One of the first benefits of this kind of energy is that it emits no greenhouse gases or waste unlike fossil fuels. It thus bypasses the global warming, rain or tangy smoky fog.

Conversely fossil fuels that are either flammable or explosive, solar energy presents no danger.

Accident ships carrying oil, it generates spills with serious impacts on the environment.

The energy of greatest danger is nuclear. Indeed, there are a number of countries producing radioactive waste so we do not know until today where they reject them.

Furthermore, in case of nuclear accidents such Chernobyl significant damage is found, among others, soil contamination.

The use of this energy to cook food limit deforestation in many countries where the kitchen uses mainly wood and charcoal.

This type of energy is then used to reduce emissions of CO 2.


However, before embarking on the use of solar energy, we must know its drawbacks.

The solar energy is dependent on weather conditions. Indeed, it provides a fairly high production in sunny areas and during the summer.

By cons, electricity production is reduced during the winter and in cloudy areas. It does not generate electricity at night. It is then necessary to make an investment on the means to store energy or to choose a secondary energy source.

In addition, it takes large-area photovoltaic panels if you want to be sure to have a proper production of energy. The system then looks less profitable compared to nuclear power in the case of a large production.

Cost of installation and durability

Cost side, the installation of a solar power system requires the intervention of the specialized companies to have an effective meeting the needs.

Moreover, we must also consider the high cost of raw materials useful for the installation of the system.

Although solar photovoltaic guarantee good returns for 25 to 30 years, beyond these periods, their performance is falling and we must change.

It is better to consider this factor in the calculation of depreciation of an investment in a solar installation.

A minor drawback for the use of a solar system is the solar cell manufacturing that requires polluting products, such as solvents.

Develop solar energy more

Still remaining undeveloped, solar energy is an energy source whose future is certain.

Today, research has greatly increased in order to minimize the adverse effects of fossil fuels on the environment; lower prices dedicated to energy and grow the profitability of this type of energy.

Theoretically, it is possible to convert up to 87% of light through a solar cell into electricity.

The record in terms of performance was in June 2012 as one could reach 43.5%. With this research, it is possible to store solar electricity, and enjoy the year round.

The use of less polluting elements in the production technology is also part of the ongoing concerns of research organizations in the field.
