Q: What is a Solar Photovoltaic System (PV system) about?
A: Photovoltaic systems (PV system) use PV module to convert sunlight into electricity. A PV system is made up of different components other than PV modules. These include an inverter for a utility-grid-connected system and when alternating current (ac) rather than direct current (dc) is required; wiring; and mounting structure.
Q: Benefits of Renewable Energy
A: Renewable energy sources are clean and inexhaustible. And as the name tells us it is renewable and does not use resources that can never be replaced. Hence, Renewable energy has a much lower environmental impact than conventional sources of energy.
Q: How long do photovoltaic (PV) systems last?
A: Basically, PV systems are designed, installed, and maintained to operate for more than 20 years. The basic PV module (interconnected, enclosed panel of PV cells) has no moving parts and typically has lifespan of 25 years above. The best way to ensure and extend the life and effectiveness of the PV system is by having it installed and maintained properly by Certified Approved Photovoltaic Service Provider.
Q:How do I know if I have enough sunlight for PV?
A: A photovoltaic (PV) system needs unobstructed access to the sun’s rays for most of the daytime. Shading on the system can significantly reduce energy output. Hence, visual assessment on the building is needed to determine if the location is suitable for installation.
Q: What is Feed in tariff and when it been implemented
A: On April 4th 2011, Malaysia parliament passed the Renewable Energy Act 2010 bill, which is aimed at promoting the development of RE in Malaysia under the Feed-in-Tariff (FiT) effective 1st December 2011. Feed-in-Tariff (FiT) is a policy mechanism designed to accelerate investment in technologies by allowing eligible Renewable Electricity Generator selling back the generated electricity they produced to the TNB at higher tariff rate. Among many types of renewable energy such as bio-mass, bio-gas and small hydro, residential homes would benefit most from Solar Photovoltaic as a renewable energy source.
Q: How Feed in tariff (FiT) can benefit citizens of Malaysia
A: Implementation of feed-in-tariff (FiT) mechanism under the Renewable Energy (RE) Act allowed individuals to earn income by selling electricity generated from renewable resources at home. Under the RE Act, the public will be able to sell electricity generated from RE to utility companies such as Tenaga Nasional Bhd at higher tariff rate (from rm1.2/unit and above) contracting with TNB for period of 21 years.
Q: What is the payback of the system
A: A system producing 5KW of electricity at home will generate electricity of more than 15 units per day converted to earning more than RM600 a month through selling back of generated electricity to utility company and the ROI for the total system cost and maintenance will be within 5 to 6 yrs.
Q: Application of PV system
A:PV system is best suited on most of landed residence. It can be installed on roof top of landed residence, commercial building such as shop lots and office, factory, and petrol station etc.
Q: How big a solar energy system do I need?
A: The size of solar system needed depends on several factors such as how much electricity you use, the size of your roof, and how much you’re willing to invest. Also, do you want the system to supply your complete energy usage or to supplant a portion of your higher cost energy usage? You can contact a Certified Approved Photovoltaic Service Providerto determine what type of system would suit your needs.
Q: Why should I purchase a PV system?
A: People decide to buy solar energy systems for a variety of reasons. For example, some individuals buy solar products to preserve the Earth’s finite fossil-fuel resources and to reduce air pollution. Others would rather spend their money on an energy-producing improvement to their property than send their money to a utility. Some people like the security of reducing the amount of electricity they buy from their utility, because it makes them less vulnerable to future increases in the price of electricity.
