Pros and Cons Solar Energy

As long as the sun shines, solar energy is a free resource. So why aren't we using the sun's rays to light our homes and warm our morning showers? Like other sources of renewable energy, solar energy has its pros and cons.

Solar Energy Advantages

Clean
Solar energy is clean. No fossil fuels are used to produce heat or electricity with solar energy. The only pollution produced is in the manufacturing, transporting and installing of solar panels.

Easy Installation
Solar panels are usually easy to install on different roof types, including flat or pitched roofs.

Maintenance Free
Solar energy systems require little to no maintenance and last for several decades.

Multiple Uses
Among other things, solar energy can be used to light your home, cook your meals and heat your water.

Safer
Collecting energy with solar panels is much safer than mining coal or transporting oil from overseas.

Storage
When a solar energy system produces more energy than necessary, it can be stored for later. This is especially convenient for those times it's not producing electricity, such as after the sun has set or on cloudy days. If there is excess energy in storage, your utility company may be willing to buy it from you.

Tax Credit Incentive
Receive a tax credit of up to 30% on solar panel costs through 2010. See the Energy Star website for more information.

Useful in Remote Locations
Very remote locations are often difficult for power companies to access. In many of these areas, solar panels are a great option.

Solar Energy Disadvantages

Generated Only During Day
For solar energy to generate electricity, it must be daylight. During night hours, stored solar energy or an alternative energy source must be used.

Location Matters
Solar power is not the best option for all locations. Regions that have an abundance of cloudy, overcast, or rainy days find it hard to benefit from solar power.

Pollution
Pollution can interfere with the efficiency of solar panels. Solar energy may not be an option in large cities or heavily polluted areas.
