One little-known fact, however, is that solar panels are initially contributory to greenhouse emissions because it takes power to manufacture a solar panel, that this energy is very often fossil-based, and front-end loaded, and that therefore there is a time period during which the solar panel has actually added to carbon emissions rather than detracted from them. Until such time as the solar panel has produced energy equivalent to the energy used to manufacture it (its fossil-emission payback period) it is actually a contributor to greenhouse gas emissions. This fossil-emission payback period is generally considered to be five to ten years.
Low power solar panels are normally available in 12 v or 14 v configurations, while high power panels are available in 24 volt. As solar panels are DC, you may normally need a power inverter that changes it from low-voltage as Direct Current to another-voltage Alternating Current to change it to be compatible with the voltage and type that feeds both the home and the grid.
Conventional solar panels are constructed using twin sheets of semiconducting silicon, combined with phosphorus and boron atoms. Amorphous silicon solar cells are a highly powerful, emerging array of photovoltaics that differ in output, structure, and manufacture than traditional photovoltaics that use crystalline silicon. The H-AS solar panels are produced in the same way, but they are made just 1 micrometer in depth by laying down polymorphous silicon at very high pressures and temperatures.
Solar panels are normally maintenance free and many manufacturers will supply a guarantee of electrical output often for as long as 20 years.
Solar panels are installed on whichever side of your house that gets the maximum solar exposure. In locales south of the equator this would be the north-facing aspect, and in locales north of the equator its the south-facing aspect.

Pahang (Malay pronunciation: [paˈhaŋ]; Jawi: ڤهڠ), officially Pahang Darul Makmur with the Arabic honorific Darul Makmur (Jawi: دار المعمور, "The Abode of Tranquility") is a sultanate and a federal state of Malaysia. It is the third largest Malaysian state by area and ninth largest by population.[2] The state occupies the basin of the Pahang River, and a stretch of the east coast as far south as Endau. Geographically located in the East Coast region of the Peninsular Malaysia, the state shares borders with the Malaysian states of Kelantan and Terengganu to the north, Perak, Selangor and Negeri Sembilan to the west, Johor to the south, while South China Sea is to the east. The Titiwangsa mountain range that forms a natural divider between the Peninsula's east and west coasts is spread along the north and south of the state, peaking at Mount Tahan, which is 2,187m high. Although two thirds of the state is covered by dense rain forest, its central plains are intersected by numerous rivers, and along the coast there is a 32-kilometre wide expanse of alluvial soil that includes the deltas and estuarine plains of the Kuantan, Pahang, Rompin, Endau, and Mersing rivers.[6]
The state is divided into 11 administrative divisions called daerah (districts) - Pekan, Rompin, Maran, Temerloh, Jerantut, Bentong, Raub, Lipis, Cameron Highlands and Bera. The largest district is Jerantut, which is the main gateway to the Taman Negara national park. Pahang's capital and largest city, Kuantan, is the eighth largest urban agglomerations by population in Malaysia. The royal capital and the official seat of the Sultan of Pahang is located at Pekan. Pekan was also the old state capital which its name translates literally into 'the town', it was known historically as 'Inderapura'.[7] Other major towns include Temerloh, Bentong and its hills resorts of Genting Highlands and Bukit Tinggi. The head of state is the Sultan of Pahang, while the head of government is the Menteri Besar. The government system is closely modeled on the Westminster parliamentary system. The state religion of Pahang is Islam, but grants freedom to manifest other religions in its territory. Pahang is categorised as medium ethnically diverse state with 0.36 of ethnic diversity index in 2010. It is ranked 5th least diverse among Malaysian states and territories, after Terengganu, Kelantan, Melaka and Perlis.
