Solar energy is most popular in Europe and the United States, but where is it most useful? Solar energy is useful anywhere. However, it is most easily generated in particularly sunny locations where solar collectors can amass large amounts of sun. It is not necessary for it to be sunny every day, as solar collectors come with a means of storage – a battery for photovoltaic panels, and circulation tanks and car parks for radiant heat collectors.
Solar energy can be collected and used any time of year and during most seasons as long as the sun is available. Particularly overcast locations make it much more difficult to collect solar energy. However, even if there is lower sunlight, it is still possible to use solar energy in different ways.
Solar power is measured in watts. Whether or not it is possible for you to collect all of the energy you use because of lower sunlight, it is still possible to put a large dent in your electric bill with the use of even a small amount of solar energy. Most households use about 25kWh a day in energy. To find out how many watts of sun there are on average in your area, check with your local library. Once you know the average amount of solar watts for your area, you will be able to calculate how many solar panels are needed and how much energy can be generated on average. Most individuals find that they can take 75%-100% off their annual energy bill with the use of solar energy.
Solar energy can be generated in electrical or radiant form. This means that the majority of household appliances can be run off solar energy and water can also be heated. Radiant energy also helps to run air conditioners, heat floor coils and more.
Solar energy can also be used in other ways. Whether or not you are generating solar energy through electrical or radiant forms, you can still use the energy that occurs naturally. This is easiest in places where the home can have the majority of its windows facing the southeast (in the Northern Hemisphere). In the Southern Hemisphere it is most productive to have the house’s major windows facing the north. Having many large windows open to the aggressive sunlight allows for the sun’s natural solar energy to heat the home as well as to supply the house with natural lighting. This uses solar energy significantly as well as lowers carbon usage and the utility bill. It is also a wise idea to use fewer windows on the opposite side of the house with stronger walling to keep out colder weather.
While solar energy is more easily used in locations with optimum sun, solar energy is still available everywhere. Excessive shading may make it more difficult to find a location for solar panels and extreme weather may affect collecting and cleaning, but it is always possible to use some solar energy.
