Solar power is one of the biggest achievements that we have made in the world of technology. Thousands of people have put their time and energy into figuring out how it works and how it can help us with our everyday lives. They have discovered that it can be used to light up homes, heat them, and provide them with the water they need.

Many of us are fascinated by the technology that is solar power – but so few of us understand exactly how it is able to store all of the power that the solar panels collect. All of the energy comes from the sun – which is why you do not have the ability to collect it during the evening hours when the sun is hidden from our view.

Because of this special devices had to be made that would be able to store it for hours on end and with little problems. There are thermal mass systems that have the ability to store the energy in the form of heat for everyday temperatures or for certain seasons.

These systems are more commonly produced with materials that are able to withstand high heat. This includes earth, stone, and water. Some of the more unique and well produced systems have the ability to lower peak demand, lower the heating and cooling requirements, and change the time it is supposed to be used during the off peak hours.

The phase change materials are also used for thermal storage and are some of the more affordable types. They are more popular among residential homes where they are easier to get a hold of and simple to install. These materials include Glauber’s salt and paraffin wax. In fact the first Glauber’s salt solar power heating system was used in 1948 in a home in Massachusetts.

Molten salts are used to store solar energy at high temperatures. This is useful for storage medium and are more  valuable because they are cheaper and able to withstand some of the more extreme heat temperatures. There are also off-grid PV systems that use rechargeable batteries to hold in extra amounts of electricity.
