The many advantages and disadvantages of solar energy


Advantages of solar energy

Solar energy has many environmental and financial benefits that few people know about from. The amount of sunlight reaching the Earth is over 6000 times the amount of energy consumed.Solar is an incredibly clean source of renewable energy and has the highest density of power between renovables.No energy sources there are no emissions during the use of solar panels.

One of the greatest benefits of the use of solar is that requires very little maintenance.Operating costs are incredibly low compared with other methods of energy such as wind, geothermal, gas natural or combustible fossils. the use of off-grid power, solar energy is very advantageous due to its ease of use. Households in the rural areas, satellites and remote applications have used solar panels for energy production for years.

Grid connected solar electricity can be used in a distributed manner and provide electricity locally to companies and households. This reduces the power lost through the transmission of electricity.

Disadvantages

Solar photovoltaic systems are very expensive to install.There have been some concerns about the value of the photovoltaic depreciated as sells the House.Much of the value of the installation you may lose if the homeowner moves and home buyer places less value in system solar.La city of Berkeley in California has devised a solution by adding a tax transferred to the House to pay for solar panels.

Period depreciation that can run as 15-20 years is seen as too long for many people that want to get a rapid return on investment. Another disadvantage is that solar does not work at night and on cloudy days demasiado.Un storage device is required to store the energía.Durante to usable AC-DC power conversion process, there is a loss of energy from 4-12%.
