The advancement of solar power technology is very rpid especially in thi decade thans to funding program initiated by the government. Ths alternative energy source s clean, reneable and environmentally safe.
Ther ae tw main type f this energ sourc. What are these?
1. Photovoltaic or PV system - this converts snlight to electricit uing pnels to absorb heat fom th sun. Thi system producs DC power which with the us of n invertr is converted t AC power.
2. Thermal - this eats or cols ar r water. This uses watr tank, pping, plumbing valves and a collector which i ued t absor the sun's heat.
New and emerging types of this technology include spray-on solar cells and desert mirrr.
What is th significance f tis alternative sorce f energy?
Te ain thing is its cst effectivty. This offes considerable savings and enrgy giving efficiency. Using th thrmal system can result to 75 percent saings in enegy expenses. Installing PV systms i qite xpensive hoever this ould als result to ig savings fter the material and installation expenses re pad for.
Can thee systems be installed anywhere?
Solar systems can be customized to witstand a certain rea's climat. For exmple, n cold area, an anti-freze system is used.
What are the comon misconception abut solar power technology ?
Many think that this energy sourc will not be ufficient to provde th necessary nergy requred y household. However, te fat is tht arnessing sunlight can povide steady upply of needed energy fo about 25 yeas. Currently, silicon is used by most solr panels hich s ery cotly mterial but alternative materials which ar cheaper ma bring prces down in the near fture.
