There are various ways to lower energy consumption such as low energy lighting system and energy efficient appliances. However, controlling where the electricity comes from can also help get this continually rising expense under control. One way of handling this concern takes advantage of the best asset that these beautiful islands have, an abundance of sunshine. Installing a series of Solar Panels in Hawaii can dramatically reduce dependence on the local electric supply.
Determining the total number of panels usually requires some assistance. This is necessary because one needs to know how much energy is consumed to determine how many panels are required. Combining photovoltaic cells with solar water heating and the cost of comfort can be greatly reduced. Supplying hot water takes about thirty percent of the annual electric usage.
The two most common ways to install solar panels are ground based stands and roof mounts. This decision will be based on the amount of available property and the structure of the roof. Modern panels are lighter than earlier versions, but the additional weight could still affect the roof.
Another consideration when mounting the panels on the roof is the brackets. Mounting systems need to limit the damage to any roofing materials and they need to be protected from corrosion. Experienced contractors use either galvanized steel or aluminum. Steel creates a stronger and more reliable bracket, but it may eventually develop corrosion concerns. Aluminum can easily resist the elements, but it is not as strong as steel. Strength can be an issue whenever those Pacific storms move over the islands.
One of the more important benefits of using solar energy is that it releases no carbon dioxide or other pollutants. Unfortunately, Solar Panels in Hawaii may not always provide an adequate supply of electricity because the amount of solar radiation is variable. For example, there is little sunshine at night and limited sunlight during severe storms. This problem is offset by keeping a connection with the local electric utility and if the building is not consuming energy during the day, it may be possible to lower the bill even further because excess electricity can be returned to the grid.
