isadvantages of Solar
The primary disadvantage of solar power is that it obviously cannot be created during the night. The power generated is also reduced during times of cloud cover (although energy is still produced on a cloudy day). Solar panel energy output is maximized when the panel is directly facing the sun. This means that panels in a fixed location, such as the building above, will see a reduced energy production when the sun is not at an optimal angle. Many largescale solar "farms" combat this problem by having the panels on towers (above left) that can track the sun to keep the panel at optimal angles throughout the day.
Even todays most efficient solar cells only convert just over 20% of the suns rays to electricity. With increased advances in solar cell technology this number is likely to increase. Besides their low conversion efficiency, solar panels can be a substantial initial investment. However, the cost of solar panels incurred is only the initial cost, after buying and installation they create free energy for use.
