Answer:
1. Solar Electricity
This is one of the solar energy applications that has gained a lot of momentum in recent years. As solar panel costs decline and more people become aware of the financial and environmental benefits of solar energy, solar electricity is becoming increasingly accessible. While still a very small percentage of the electricity generated in the U.S. (1.9% in 2017), solar electricity is growing rapidly (almost tripling over a three year period and up +40% versus 2016) according to the U.S. Energy Information Administration.
A distributed solar PV system is typically installed on the rooftops of homes or businesses. These solar power systems generate electricity to offset the property owner’s usage and send any excess production to the electric grid.

2. Solar Water Heating
Uses for solar energy extend to water heating systems. Most solar water heating solutions create hot water that is consumed inside the home. Solar water heaters use a rooftop cell to absorb the sun’s heat and transfer it to the water tank. Solar water heaters usually have a five to ten year payback according to the U.S. Department of Energy (DOE).
Another application of solar energy, especially in the southern and southwestern U.S., is heating swimming pools. Water is circulated to a collector where it is heated by sunlight and then pumped back into the pool. With costs between $3,000 and $4,000 and a payback of 1.5 to 7 years, the U.S. DOE says that “solar pool heating is the most cost-effective use of solar energy in many climates.”
3. Solar Heating
Typical uses of solar space heating systems include powering radiant floors or pairing with a Forced Hot Air (FHA) system to heat a home. Passive solar home design can also heat homes and businesses in the winter by taking into consideration the placement of windows and the selection of materials used in the building.
4. Solar Ventilation
Solar ventilation solutions such as solar attic fans can reduce the burden of your HVAC by helping to cool your home during the summer. This may be a good option if you are not able to install a solar PV system that offsets your home’s entire electricity use. One innovative product is the Solatube solar attic fan.
Commercial and industrial applications of solar process heat include solar ventilation technologies that can preheat a building’s air in cold climates, reducing energy costs.
