Solar roofing has several benefits and comparatively few drawbacks. Solar roofing uses photovoltaic energy to convert sunlight to electricity. Generally, a solar roof consists of several photovoltaic cells joined together to form a solar panel. Several of these panels are then installed on the roof, where they work to convert sunlight to electricity. It can result in huge savings in energy bills, and is also environmentally friendly in nature.
Benefits of Solar Roofing
Solar roofing is a great solution for our ever-increasing demands, because it requires sunlight, which is inexhaustible and always available in most parts of the world.
A solar roof can drastically reduce your utility bills, because you will no longer be reliant on traditional methods of power supply in your home. Most homeowners who install solar roofs see a significant cut in utility bills in the first year itself. You can achieve complete independence from local utility companies and the ever-increasing rates for electricity. Most governments also offer attractive tax credits for installing a solar roof system.
Long Lasting and Maintenance Free
A solar roof is built to last for many long years. In general, costs of maintenance and repair are minimal as compared to normal roofing methods and materials.
Solar roofing is an environmentally friendly option, because you no longer have to burn fossil fuel to generate electricity. We have a limited supply of non-renewable energy on earth, and our demands are fast exceeding the available supply. By turning to solar energy as an alternative, we can greatly reduce our need on exhaustible resources.
Reduction in Toxic Emissions
Solar energy is a clean and green option. There are no emissions involved. Unlike traditional methods of generating electricity, solar roofing does not involve emissions of greenhouse gases that contribute to global warming. It is also better for the overall health and well being of the occupants of a household.
Though solar roofing cannot function without sunlight, technology has made possible the use of backup options for providing energy. The use of backup ensures that there is a continuous supply of power, even during the night or when the weather is unfavorable.
Drawbacks of Solar Roofing
In addition to the above advantages, solar roofing also has some drawbacks. However, in comparison to the magnitude of the benefits, most people find the disadvantages insignificant.
High Set-up Costs
Solar roofing can be quite expensive to set up and install. Some parts of the roof such as corners and ends usually consist of traditional, non-solar roofing material. In general, the cost of installation and materials for a solar roof is much higher as compared to traditional roofing. However, when you consider the long-term savings, the initial costs can be justified.
Dependence on Sunlight
Solar roofing functions on the availability of sunlight. On cloudy days and during the night, the photovoltaic cells can not do their job. As a result, adequate alternate sources of power may have to be kept on standby.
