In the recent past, there has been a growing need for solar energy through solar panels installation in homes owing to its environmental and economical benefits. The solar panels are made of photovoltaic cells that convert sun energy into electric energy used for heating purposes or to power electrical devices. The energy generated is directly transmitted to the electrical appliances or gets stored in a battery for future use. Although a difficult task, the process of installation can be easily achieved with proper assembly and electrical knowledge.
The installation cost largely depends on the panel system used. In general, single panels that generate around 75 watts of energy cost $900. While an energy efficient panel producing 2 kilowatts of energy, will cost around $16,000-$20,000, and 5 kilowatt systems are worth $30,000-$40,000.
Solar panels are basically installed on the rooftop of homes. They can also be placed as free standing units close to the structure, provided there is enough space. The panels can be mounted using flush, poles or roof ground mounts. Flush mounts are used for installation on the top of a roof. Pole mounts support small or single solar panels, while roof ground mounts are applicable for roof and ground installations.
The panel needs to be perfectly angled to direct sunlight, as the system produces solar energy in full capacity only when positioned facing the sun. It is also necessary to eliminate all hurdles that block sunlight or else it will work ineffectively. Depending on the need, the panel needs to be tilted slightly to attain the maximum amount of sunlight. It can be tilted to the degree of latitude the panel is fixed at.
For instance, panels positioned at 15-25 degrees latitude need to be tilted to the same degree while panels at latitudes of 0-15 degrees are to be titled to 15 degrees. Once fixed, the solar panel needs to be tested to make sure it is protected and leak proof, too. Following this the panel needs to be connected to an electric circuit box or an inverter running on battery power.
Solar panels installation in homes offers numerous benefits. The initial investment is only a one time cost which can be regained within a few years of installation. It is both environmentally and user friendly. The solar energy uses no fuel to produce energy and also does not release any harmful pollutants into the environment. Solar energy systems are easy to use and require less maintenance. The major benefit is that it enables you to offset all energy costs thereby saving on electrical bills. Solar panels installation is a cost effective choice for all homeowners and aids to generate clean and green power.
