Solar Energy Pros:

• Solar panels give off no pollution; the only pollution produced as a result of solar panels is the manufacturing of these devices in factories, transportation of the goods, and installation.
• The production of energy from the use of fossil and some renewable fuels (e.g. wind turbines) can be noisy, yet solar energy produces very quietly.
• Solar energy can be very efficient in a large areas of the globe, and new technologies allow for a more efficient energy production on overcast/dull days.
• Solar panels can be installed on top of many rooftops, which eliminates the problem of finding the required space for solar panel placement.
• Another great pro of solar energy is the cost. Although the initial investment of solar absorbers may be high, once installed, they provide a free source of thermal power, which will pay off the investment over the coming years.
  The use of solar energy to produce thermal power allows the user to become less dependent on the worlds fossil fuel supplies.

Solar Energy Cons:

• The major con of solar energy is the initial cost of installation. But the cost is reducing as manufacturing efficiencies are modernising.
• Solar energy is only able to create thermal during daylight hours. This means for around half of each day, solar panels are not producing thermal for your home.
• The weather can affect the efficiency of thermal uptake.

Overview:

Above is a list of many solar energy pros and cons, and although not definitive, you can see how the number of pros relating to solar energy, greatly outweighs the cons of solar energy.
