Disadvantages of Solar Energy

By Christopher Eyres


Downsides of Solar Power / Is Solar Power the Ideal Energy Solution for the Future?

Mankind's use of solar electricity to generate electricity is arguably one of the best achievements of our civilization and will probably be prepared for a much larger role to play in man's future. Advances in our technology that give the chance to harness sunlight to generate heat and electricity for a large array of uses is amazing.

Drawbacks of Solar Power / Getting a Handle On Our Dependencies

All our lives are so dependent on electricity at the present state of our technology. If we want to feel hotter we get a heater. If we want to feel cooler we buy electric fans or air conditioning units. We do not think carefully we just plug in our appliances and they work faultlessly most of the time. How different would things be if we had to rely on solar power?

When all variables are factored into the mix there's no perfect answer for a source of energy. Issues and consequences regarding reliability, price of production, primary capital outlay, payback times, and pollution all need to be taken into consideration.

Downsides of Solar Power / Is Solar Energy Unlimited?

In theory, solar electricity is an energy source with the most potential. The source of the power is virtually inexhaustible ( the sun ). Solar energy produces no pollution, no carbon print, no odorous emissions, and no aggravating noise. There are however a few things which is stopping solar energy from being used more extensively.

What are the Downsides of Solar Power? What comes next is an inventory of disadvantages of solar power that's not in any particular order of significance.

High first capital outlay. The opening cost of installing a solar power system can be exceedingly high for some budgets. The cost of buying and installing solar cell arrays is a bit steep. Payback times may reach from 10 to fifteen years before it is possible to even break even with your initial investment.

Dubious reliability. It is patently very unlikely to provide power for your home with a solar array at night if you don't have a system in which to store power. This suggests batteries at our present level of technology. So you may possibly still have to draw electricity from the area utility grid.

Availability of sunlight. The position of your solar array is of major seriousness in the generation of electricity. This suggests that some homes won't be ideally fitted for conversion or for installing a solar energy system.

Polluting materials utilized in solar energy panels. The majority of photovoltaic panels are made of silicon and other metals that are probably noxious like mercury, lead, and cadmium. This is the filthy secret of this "clean" technology.

The potency question. The current potency rate of most solar energy panels is just a mere 40 p.c. This means that 60 p.c of the sun's power is wasted. There are some state of the art solar cells that can reach a top performance of eighty %. There are continuing technical advances that increase efficiency and lower costs.
