As sunlight hits the cells, electrons are knocked loose, creating an electric current with the conductors attached to the semiconductor. Cells can be combined to make modules which can be put together to make arrays.]]> 2019-04-08 13:48:28 UTC https://padlet.com/01sniedringhaus/nb8q2uyc95f4/wish/349495923 Advantages of Photovoltaic Cells 02klewis https://padlet.com/01sniedringhaus/nb8q2uyc95f4/wish/349496630 1. Energy is completely clean; no greenhouse gases emitted.
    2. Sunlight is free.
    3. Solar panel cost is lowering.
    4. Operation and maintenance costs for solar panels are considered very low compared to other energy sources.
    5. Silent and easy to install on ground and rooftops.
    6. Promoted through government subsidy funding(tax credit, etc).

Intermittency issues; no sunlight at night or on cloudy or rainy days.
    2. Needs to be converted from DC to AC to be used on the power network.
    3. Needs storage batteries for continuous power, increasing investment cost.
    4. On the ground, solar panels need a relatively large amount of space.
    5. Fragile
    6. Not very efficient(14 - 25%) compared to other renewable sources.]]>     2019-04-08 13:57:19 UTC https://padlet.com/01sniedringhaus/nb8q2uyc95f4/wish/349500957     Costs of Use in Houses 01sniedringhaus https://padlet.com/01sniedringhaus/nb8q2uyc95f4/wish/349501677 The main costs of photovoltaic cells come from the purchase price of solar modules, installation, system design, and the balance of system, including inverters, bi-directional billing meters, and connection devices. However, the use of solar cells can reduce electric bills.]]> 2019-04-08 13:58:38 UTC https://padlet.com/01sniedringhaus/nb8q2uyc95f4/wish/349501677 Citations 01sniedringhaus https://padlet.com/01sniedringhaus/nb8q2uyc95f4/wish/349505909
