Here are some Solar Energy Disadvantages.
I am on the good side in a debate discussing pros and cons of solar energy.
So i need some good facts to cover up these disadvantages!! thankksss
- The initial cost is the main disadvantage of installing a solar energy system, largely because of the high cost of the semi-conducting materials used in building one.
- The cost of solar energy is also high compared to non-renewable utility-supplied electricity. As energy shortages are becoming more common, solar energy is becoming more price-competitive.
- Solar panels require quite a large area for installation to achieve a good level of efficiency.
- The efficiency of the system also relies on the location of the sun, although this problem can be overcome with the installation of certain components.
Initial cost- with the state rebates, renewable energy credit system, and federal tax credits, the system will pay for itself in 4 to 8 years depending on what state you live in. Where else could an investment pay for itself in 4 years?
Large area- you don’t need a system that will offset your entire electric usage. You want a system in conjunction with renewable energy credits and electric savings, will offset your entire electric bill.
Location- actually, the earth revolves around the sun. If you don’t have southern facing roof space, you can mount a system in the ground. If that’s not an option, you’re siht out of luck.
If you decide that you want to use an off grid system, a system that uses batteries, you will not be able to receive state rebates and sell excess electricity back to the utility company.
As for cost, take a look at Nano-solar : ) http://www.nanosolar.com
As for shortages, just wait until electric cars start becoming more popular.
Take a look at EESU / EESTOR. If they come out with this battery, Nano solar and the EESU will give a lot of people the opportunity to go grid-less.

Battery technology is improving all the time. The new Prius hybrid will have solar panels panel on the car roof to help power the car. Note solar panel can be fitted on basically anything. The sumation of the little carbon savings can add up in the long run. It does not totally need to replace the carbon base energy source, but aggment it.
