The advantages of solar power systems are palpable in lower electricity bills, reduced carbon dioxide emission and adding value to the homes. To follow is an overview of how much these advantages cost.Solar Panels are based on photovoltaic solar technology. PV solar cells are the solar modules or sometimes called as solar panels form the major portion of the initial costs which a buyer has to bear.
Solar panels price is based on the power rating provided by the manufacturer but it has to be kept in mind that the average usable time is around 20% of the total life time of the solar cells. But that is not always true as there are numerous factors which are involved in the total output of the solar panels.
Initial Costs
As mentioned earlier the solar module forms the bulk of the total initial costs of the entire system to be installed. Other expenses are inverter, batteries, metering equipment, labor costs and various casing and wiring expenses. In a grid tied solar system there is no need for batteries as excess electricity is fed to the grid for which the utility company pays.
Operation and Maintenance Costs
These costs come after the installation is done and run for the life time of the system. For getting the maximum power solar panels have to be maintained by regular cleansing. Batteries and inverters have to be replaced after a few years.
Rebates Available
The above mentioned costs can easily be calculated; however there are many incentive and subsidies which the government is providing in order to encourage the use of solar power. The related information can be obtained from federal or state government’s website or from the promoters of solar power.
Suitable Location
In order to take full advantage of the solar power systems, it should be placed where it can receive maximum sun rays. If you are located near the equator then solar panels are an ideal option.
