Solar Panels 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 electricity very quietly. One of the great pros of solar energy is the ability to harness electricity in remote locations that are not linked to a national grid. A prime example of this is in space, where satellites are powered by high efficiency solar cells. The installation of solar panels in remote locations is usually much more cost effective than laying the required high voltage wires. Solar energy can be very efficient in a large area 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.
SOLAR PANELS CONS
Soldering these cells together is very tedious work and time consuming. The labor involved in the making of the panels are why they are so expensive on the market. Each cell has eight soldering points. Two on the top, and six on the bottom. They do offer pre-tabbed cells at a increased price which means less soldering. Solar Panels are very fragile and can be broken easily. An effort to keep start up costs to a minimum. Intermittence. Solar energy is only available when the sun is shining. If we want to use solar to provide power at night, we need to store the energy. Although there is a variety of options for storage, the most obvious is batteries, which are quite expensive. Low Efficiency Requires Large Areas of Land. Some of the least expensive forms of solar energy are quite inefficient (in some cases under 10%). This means that large areas of land (that could be used for other purposes) can be needed to generate the required amount of power.
