About the Solar PV System

How solar help us save electricity?

Solar PV system generate electricity during day time therefore, you are importing less energy from TNB. The excess energy from solar can be store in TNB grid through NEM program or energy storage system. Average 8kWp Solar PV system gives you RM550/month saving which normally fit our terrace roof.

I have a lot air-conditioner in my house, can solar PV system power it?

It doesn’t matter on how many loads you use in your house. Solar PV system always work together with TNB supply and TNB supply is still your primary power source.

What happens on a cloudy day?

Even a cloudy day is sufficient to generate some solar power, although a lot less than a sunny day. It’s important to remember that in a solar panel array, shade blocks the flow of electricity through the panels. Even if shading is on just one of the panels, the output of the entire array will be reduced.

How long can solar PV system last?

Solar panel typically can last beyond 25 years based on manufacturer’s design life span. Some of the system have service life up to 50 years still generating power. Inverter is the crucial part which their warranty is 5 years. Hence, it is important that you choose a good and reliable solar installer who supported by reputable manufacturer.

Is solar PV system safe?

Solar PV panel on your roof doesn’t emits any radioactive waste. Fundamental material of solar panel is silicon (kind of sands), glass, aluminium, copper and EVA which is non-toxic. Furthermore, solar panels are just a reverse engineering of LED bulb.

Due to solar PV system is an electrical equipment, therefore if give potential harm to you like electrical shock and fire. So, please ensure only solar experts handle your solar PV system. Do not try to do-it-yourself.

How do I maintain solar PV system?

The nature of solar PV system is doesn’t have moving part so minimal maintenance is required. Malaysia is blessed with rain all year round. Rain will wash away the dirt on the solar PV panels. Nonetheless, we recommend periodic inspection by us to ensure all in good condition.

How much roof space is required?

The amount of roof space required depends on the size of the system. For example, a small 1.5kWp system requires 12m2 of roof space.

What is the average solar capacity we can install?

– Depend on your consumption: We take 3 months average your consumption and estimate your solar capacity

– Depend on your roof space: Average terrace house can install 4kWp which mean 4,000-Watt peak power which will occupy your roof space not more than 26m2.

– Depend on your budget: with the above requirement met, you can install based on your budget.

How much does solar cost?

The cost of a Solar PV System can vary from RM20,000 to RM60,000 (for 4 – 15kWp) but the average is roughly RM3,500/kWp.

What if I want to sell off my house after installing Solar PV System?

The value of your house will definitely increase due to energy security on your house. You must bundle it together with your house to sell it.

Can I increase the size of my system in the future?

This depends on your roof space and the size of the inverter. If you have sufficient roof space and additional capacity in your current inverter, you could increase the size of your system. Or you could add a second system to your roof.


What is a Grid-Connected Photovoltaic System (GCPV)?

Grid connected Solar PV Systems are connected to the electricity supply grid and work if only if supply is available. An inverter converter DC power generated by the solar panels to 240V AC household supply.

What is peak-sun-hour?

Peak-sun-hour is the hour of solar panel receive full sun light. In Malaysia, average sun light per day is around 3.5 hour to 4 hours.

What are the main components in my solar system?

  1. Solar PV panel on your roof
  2. Inverter to convert DC to AC electricity and install either outdoor or indoor
  3. Protection switches and install besides the inverter or main distribution board

How sunlight is converted to electricity?

When sunlight hits the PV cells in a solar panel, electrons are knocked loose and move around. These loose electrons can be captured so they move in the same direction around a circuit. An electric current is formed by this flow of electrons in the same direction.

By connecting many PV cells to each other in a panel and wiring a number of panels together (called an array), a flow of electrons is created and produces direct current (DC) electricity. The more panels in an array, the more electricity is made.

In our homes and businesses, we use 230 Volt alternating current (AC) electricity. Therefore, a box called an inverter – usually no bigger than your average shopping basket – is used to convert the DC electricity to AC so it can be used in your premises.


How long is the wait time between booking and installation?

Install through NEM program, it takes about a month from the time you confirm until system commissioning.

How long does an average installation take?

For house small installation normally take 1 to 2 days. But for bigger it normally takes a week.

For commercial 100kWp above it normally take not more than 1 month.

Earning with Solar – HERE IS THE MONEY!

Solar PV System still expensive?

The good news is that the price of a Solar PV System has gone down roughly 70% in the last two decades. Why? Because the world is going solar. This means lower prices for the actual solar panels themselves. The bad news is that our government’s short-term energy outlook indicates that electricity bills are rising 8% every 4 year.

When is the right time and cheapest to install solar? Or can we wait until the Solar PV System cost cheaper?

There has never been a better time to go solar now. Savings are big right now. Here at EnergyPossible you can stop those rising energy bills.

What is the income generated by 4kW solar system?

FiT: 4kW x 3.5 hours sun light x FiT rate (RM1.20 per kWh) x 30 days = RM504

NEM/Selfco: 4kW x 3.5 hours sun light x TNB Tariff rate (RM0.571 per kWh) x 30 days = RM240

When ROI will be reached?

Typically recoup your investment cost in 6 to 7 years at CURRENT electricity prices. If electricity prices going up, it will shorten your ROI.

By connecting many PV cells to each other in a panel and wiring a number of panels together (called an array), a flow of electrons is created and produces direct current (DC) electricity. The more panels in an array, the more electricity is made.

In our homes and businesses, we use 230 Volt alternating current (AC) electricity. Therefore, a box called an inverter – usually no bigger than your average shopping basket – is used to convert the DC electricity to AC so it can be used in your premises.

Net Energy Metering (NEM)

What is Net Energy Metering (NEM) program?

Net Energy Metering program is the method to allow consumer use electricity from Solar PV System and store the excess energy to TNB grid. In other word, you selling back energy to Energy Company like TNB. By the end of the month, Energy Company will net-off your bill.

What is the biggest system I can install under NEM program?

For residential is base on your fuse rating and three-phase normally can install up to 72kWp. For commercial will base on your maximum demand which not more than 75% of your maximum demand.

Can I generate more than my consumption?

The excess energy you export to TNB will be record in your bill and only valid up to 12 months.

Can I store my excess energy in battery storage system?

For residential, it is not advisable to store excess energy in the battery if TNB buying tariff is more affordable than battery system. Unless you need a back-up energy for emergency purpose, you may consider. However, for commercial/industry you may consider to shift your maximum demand peak load. It will further reduce your bills.

Feed-in Tariff (FiT)

What is FiT Program?

A feed-in tariff (FiT) is an electricity policy for consumers who own Solar PV System which allow them to sell all their production to the grid through contracted fixed selling rate. The FiT is financed by the Malaysian electricity consumers who contribute 1.6% of their total electricity bill towards a RE Fund when they use more than 300kWh of electricity per month.

How is the FiT system financed by the government?

The FiT system is not financed by the government; instead it is financed by electricity consumers who contribute 1.6% on top of their electricity bills towards a specific fund called the Renewable Energy Fund. The Renewable Energy is used to pay for the premium tariff for renewable energy. however, domestic consumers who consume 300 units of electricity or less each month will not have to contribute to the Renewable Energy Fund.

Why there is the quota in FiT system? How frequent the quota is available?

SEDA have to make sure all Renewable Energy Fund (RE Fund) are utilize fairly and efficiently to solar producers. Due to limited RE fund contributed from electricity user, the quota system is introduced for first come first serve basic. Quota will open once a year but already ended 2016.

Financing Solution

Any advice on solar investment through FiT?

If customer have some amount of money that will not use during these 4 or 7 years, customer is advice to invest through their current saving for maximum benefit.

Any advice on the bank financing for solar?

Customer have three solution for financing support. One is through personal loan: the interest is quite high and is not advisable. Second is through refinancing your existing house loan. This is the best option for customer who really want to get a loan. Third is credit card. If you have zero interest facility, why not it’s one of the preferred options.

Any bank that offer solar financing?

Yes, a lot bank is offer solar loan. But you need to compare their interested rate with other option such as refinance/re-mortgage your property to buy Solar PV System.

Is there any solar panel grant from the Malaysian government towards installation costs for companies and other business entities?

Grants toward cost of installation of home Solar PV technology are available in some countries. Unfortunately, though, these grants are not available at this time in Malaysia.


Is my solar system covered by a warranty?

Absolutely! We have two category warranty; one is manufacturer back-to-back warranty and another one is our workmanship warranty. Solar PV panel’s warranty is under manufacturer normally product warranty is 12 year and performance warranty are 25 year. Inverter’s warranty by default is 5 year and can be extend to 10/15/20 year. As we stock a variety of brands, warranty specifications will differ from product to product.

What does my warranty cover?

Generally, most mechanical defects will be covered during the warranty period as long as they are deemed a manufacturing fault. Most Solar modules suppliers also guarantee 80% power production (performance warranty) for the first 25 years of your solar module’s life.

– The location of your home.

– The size of your installation.

– The value of your home.

Will my solar panels withstand extreme weather conditions?

Solar panels are designed to withstand harsh weather climates, from blistering heat to freezing cold. Our solar panels are also put through extreme hail tests, where they endure an onslaught of ice balls travelling at over 80km/h in 11 different impact locations. So, it’s safe to say that they’re pretty tough, but if you’re still worried that the weather has compromised your solar PV panels, you can get cover by Insurance we offer in our Maintenance Package. We also recommend annual servicing to maintain optimal efficiency.

Why is my solar power system not working at night?

Solar power systems work tirelessly during the day to produce power for your home. At night however, there is not enough sunlight to sustain operation. As a result, it is completely normal for your solar power system to turn off when the sun is down and then resume work in the morning.

Will my solar power system don’t work during a power blackout?

In the event of a blackout, your solar power system will switch off and remain inactive until power returns. This is a mandatory safety feature of your solar power system. It is designed to protect those who may be working on the blacked-out grid system. You must ensure that all of the switches on your solar power system are set to ‘ON’ when the grid returns to normal. If your switches are turned off, you will not generate solar electricity.

Why is there an error/fault description displaying on my system?

Disturbance in the grid, caused by voltage spikes, can make your inverter manually shut down in order to protect your property (and itself!). This can cause an error notice to display.

It is recommended that you monitor your system overnight, as generally it will correct itself. You may also try restarting your system manually following our easy guide. If you’re not comfortable doing this, or your system continues to display an error message, please get in touch and we’ll resolve the problem.

Why is my solar power system working inefficiently?

If you’ve noticed a substantial change in your energy savings, there are a number of things that you should check before worrying about a fault with your solar power system.

  1. Check how many kilowatts (kW) you’ve used in the past, compared with now, using previous and current bills. The power generated by your solar PV panels and inverter won’t grow with your daily average consumption. Put simply, if you’ve been using more power than normal, you will pay more when your electricity bill arrives.
  2. While you’ve got your electricity bills out, check the rate at which your utility is charging you for power. You may be paying more per quarter not because your solar system is working poorly, but because of additional costs issued by your supplier.
  3. Take a stroll around your property during the day and observe your solar PV panels. Check that neighbouring buildings, trees or other structures aren’t blocking sunlight from reaching the panels. Though your installer would have ensured a non-obstructed view of the sun at the time of installation, new factors may have emerged that are obstructing your panels from working properly.
  4. Visit the common problems and solutions page for more information and advice.

How do I check my solar system’s performance and kW generation?

You can check through your monitoring platform which we provided.

Should I get my solar power system serviced?

Ask Energy Possible Any Issue About Your System

What you spend on electricity?

The typical Malaysian family spends more than RM 6,000 per year on electricity alone. By going solar, your energy saving could be RM60,000 over the course of twenty years.

How Much Does Solar Increase Your Property’s Value?

According to research done by National Renewable Energy Laboratory, each additional RM1 in energy bill savings (from your solar installation) adds RM20 to your home’s total value. This rule of thumb varies depending on a number of factors, including:

– The location of your home.

– The size of your installation.

– The value of your home.

What is the average consumption in Malaysia’s family?

Malaysia electricity consumption is averagely 3,012 kWh per household per year or 251kWh per month.

How can we save more money from utility company?

In Malaysia, air-conditioner draw around 40% of your electricity bill. If you can control your degree at the optimum temperature, it will help a lot. When setting the air con’s thermostat at 16°C, remember that every degree drops equals to a 10% increase in energy consumption. However, before you can control your bill, you must know your electricity usage.
