What is the difference between Solar Heating System and Solar Photovoltaic System for home?
Solar Heating System utilizes solar concentrators to convert sunlight to heat, which becomes the source of water heating system. The concept is similar to using magnifying glass to start a paper fire. The hot water is then stored in a water tank for later use.
Solar Photovoltaic System converts sunlight to direct current, which is similar to electricity from battery. The direct current is then converted to alternate current and connected to existing electrical circuit for a property. The electricty is not stored and it will be consumed by the property and neighbouring community.
If I have a solar PV system, do I still need to use the electricity from TNB?
Yes, the reason is the solar electricity is generated during day time and it is not stored for later use during the night. Therefore, you still need to use the electricity from TNB at least during the night.
Can I use solar electricity to reduce my electricity bill?
Yes, indirectly. You still need to pay for the amount of electricity consumed. You can use the payment received from TNB for the solar energy generated to pay for the electricity consumed. In some cases, you may be able to pay off the electricity bills and pocket the extra money you received.
What is the capacity that I need?
In most cases, it largely depends on your budget. As a rules of thumb, 4kW for a double storey link house and 10kW for a bungalow, 24kW to 180kW for commercial or factory building.
How will I be paid for the solar electricity generated?
A new meter will be installed and it will record the solar electricity generated. Based on the monthly reading of the meter, TNB will make the payment directly into your designated bank account every month.
What if I want to sell my house which already has a solar PV system installed?
You can transfer the FiT Approval to the next owner.
How long can the solar PV last?
It can last longer than 25 years. Solar PV module comes with at least 10 years of limited warranty. However, the performance of the Solar PV module will degrade gradually at around 0.8% annually.
