| Solar power is pollution free and causes no greenhouse gases to be emitted after installation | Solar panels can be expensive to install resulting in a time-lag of many years for savings on energy bills to match initial investments. |
| Reduced dependence on foreign oil and fossil fuels | Solar power is used to charge batteries so that solar powered devices can be used at night. The batteries can often be large and heavy, taking up space and needing to be replaced from time to time. |
| Return on investment unlike paying for utility bills | The more electricity you want to produce, the more solar panels you will need, as you want to collect as much sunlight as possible. Solar PV panels require a lot of space and some roofs are not big enough to fit the number of solar panels that you would like to have. |
| Solar will reduce your electric bill and give you control over a fixed cost | Clouds and storms also restrict the amount of energy you can produce by blocking light rays that would have otherwise been absorbed by the solar panel. |
| With solar energy, you’ll purchase less or no electricity from the utility, meaning you no longer need to be concerned about rising electric rates | Depending on geographical location the size of the solar panels vary for the same power generation |
| Solar cells create no negative impact at all. On the other hand, the giant machines that pump oil are noisy polluters, and therefore very unfeasible | No solar power at night so there is a need for a large battery bank |
| Almost no maintenance is required to keep solar cells running. There are no moving parts in solar cells, making it difficult to harm them | Lower solar production in the winter months |
