Solar Pool Heating Fort Lauderdale http://greenenergytek.com/
There is really no reason to even consider getting a solar energy system if you live in an area that rarely sees the sun. This does not mean that a less than reputable company will not try to sell you a solar system though. If your roof does not receive at least 6 hours of full sunlight per day, you should not consider solar power.
There is no need to tear apart your roof to use solar energy. You can make small switches like putting in solar powered outside lights. They charge their batteries during the day, switching on and providing illumination all night.
