Solar power systems create free energy from the Sun. Solar power system are using the sun to the process light or heat into an energy source.
It is becoming a reliable renewable energy alternative to regular power sources like coal powered electricity in urban areas. Solar Power systems are even been used in outer space to power satellites and even the international space station. Solar power system as renewable energy sources are used in homes for lighting, electricity generation and water heating. Renewable energy like solar power is becoming even more popular as the cost of fossil fuel continue to rise. Solar panels both thermal and photovoltaic are designed to collect the free energy from the sun.
Different applications of solar power.
Once the solar energy is collected by the solar panels installed the solar power has to be converted into energy either electrical or heat. Solar thermal application processes involve using the energy from the sun to directly heat air or liquids. The process of photoelectric application involves the use of photovoltaic cells to change the energy into electricity.
Solar power challenges.
Solar power poses no harm to the environment. There is an abundance of solar power available. one hour of sunlight beams enough energy to planet earth to satisfy our energy needs for a year. Even though so much free renewable energy reaches earth every hour of the day less than one tenth of one percent of global energy demand is sourced through solar power. Why are we using so little of this freely available solar power ?
- Cost is currently the main factor. Technology to produce electricity from the sun is still more expensive as burning fossil fuels
- Storage of solar power. Solar power does not work at night, so energy captured during the day still has no efficient and cost effective way of being stored.
Even though solar power has its challenges it is still a very good choice going forward. Solar thermal energy for hot showers and baths is already proven very cost effective and is growing in popularity. Once the initial investment in solar thermal power is made the solar power is free and reduces your fossil powered energy by about 30%.
Solar power is also very economical to use in remote areas where it is expensive to provide common fossil powered electricity. Your off grid systems with battery backup prove to be very successful in those areas.
