Recently, the demand for solar power has increased, due to rising electricity cost and financial meltdown. Customers are looking for an economically viable option with long term cost efficiency. To promote solar power, governments have introduced subsidies on installation and the cost of solar panels. Solar energy provides an alternative source of generating power. Electricity has become expensive by the day. For business firms, rising over head costs has been a constant concern. Electricity cost constitutes a major portion of overheads cost. Since electricity rates are variable therefore it affects the planning and productivity of an organization. Due to these reason, many organization and commercial set up are opting for solar plants. Earlier, installing a solar plant was costly and this discouraged many individual and corporate customers from opting it. Now, with the boom in the demand for solar power, updated solar PV panels are introduced and they are available in almost thirty percent less cost.
Solar panels are generally installed on roof. It is pivotal to select a location for installation that receives optimum amount of sunlight. Generally, roof is an ideal location for solar panel installation. In many cases, roof may not receive proper sunlight; due to the direction of the house or surrounded by natural vegetation. If roof do not offer an ideal location, ground mounted solar panels are available. Generally, farmlands that are located in natural surrounding opt for ground mounted solar panels. Apart from overshadowed roof, farmlands require bigger solar plants and roof structure may not be strong enough to support large solar panels.
Ground mounted solar panels are installed on frames that are made of galvanized steel or aluminum. The panels are attached in a tilted position about thirty degrees to receive optimum level of sunlight. These panels rotate to follow the position of the sun. Also, the frame is half rigid so that during winters when position of sun is low, panels can be manually adjusted to follow the position of the sun. Ground mounted solar panels have more advantage than roof installation. For large solar plants and sun tracking device, ground is a far better choice than roof.
Solar power plant installed on the ground have few constrains. It is more costly than roof top installation. Also, in cities, resident do not have enough ground space to install a solar plant. For residence in cities, roof is an ideal position for solar power installation. Also, solar panel need to attach to concrete ground surface, this require concrete ground structure to be built in the identified location.
