  • How can I measure the success of an energy audit?
    The success of an energy audit can be measured by comparing energy bills before and after implementing the recommended energy efficiency measures. Other metrics like energy use intensity (EUI) and greenhouse gas emissions can also be tracked.
  • How do solar system works?
    As sunlight cascades on the solar panels, Direct Current (DC) power is produced. The DC power flows to an inverter where the DC power is transformed into Alternating Current (AC) power. This AC power is what the electric grid and your home runs on. The power or energy then flows to power your home or directly to the electric grid. You can also divert the energy from solar panels to a battery to store excess energy. Batteries also operate as DC power however can power your house from a few minutes to a couple of hours.
  • Does solar power work at night or on cloudy days?
    Solar Panels require direct sunlight to produce power. Batteries are a great way to cover your power when the sun is not shining. It also works on cloudy days or when the sun isn't shining as bright. However, the power output can be slightly reduced as compared to their average optimal generation under a sunny day.
  • How much do solar panels cost?
    The price of solar power has dropped drastically over the past decade. Cost really depends on a lot of factors such as brand, size, type, and other things. Our smallest system would cost up to RM 12,000 for a 3kWp system.
  • What are the advantages of solar panels?
    The fuel source (the sun) is free, so you don't have to buy a fuel source to generate power. Because there isn't fuel needed, solar panels do not put off any harmful emissions, which is great for combatting climate change or reducing pollution. Solar power can also help you get power for an off-grid setup, so you don't have to rely on the electric grid 100% at the time. Additionally, Solar Energy is relatively efficient, durable, and long lasting.
  • Do solar panels work in the rain?
    Yes, as above, solar panels can work in the rain, though power output might be slightly altered. Rain is actually great for cleaning dust from your panels and reduces the need to clean your solar panels everyday.
  • How many solar panels are needed to power a house?
    On average of a 1000 kWh consumption , it is advisable to install up to 80% of your current consumption which is around 20 solar panels. However, Enercon Malaysia can conduct a site assessment on your intended site of installation and advise further on the suitable solar system.
  • Do solar panels work in a power outage?
    Yes, especially if your solar system is connected to a battery as backup grid. You will continue to have power as according to your battery capacity.
  • Is solar energy cheaper than normal electricity?
    Solar power is cheaper as it acts as a hedge for future spike in electricity tariff rates. With alternative power from the sun, you will consume less independently from the local electricity supplier.
  • Will I still receive an electric bill if I have solar panels?
    Unless your solar energy system includes battery storage and you are fully off the grid, you will still receive a bill from your utility.
  • How much will solar panel maintenance cost?
    Solar panel systems are made of durable tempered glass and require little to no maintenance for the 25 to 35 years that they will generate power. In most cases, you don't even need to clean your solar panels regularly. If something does happen, most equipment manufacturers include warranties, although warranty terms depend on the company.
  • Should I buy or lease my solar panel system?
    Buying or leasing your solar energy system depends on your reasons for going solar. If you are interested in maximizing the financial returns of your solar energy system, buying the system is probably a better decision for you. However, if you prioritize an easy, maintenance-free way to reduce your energy bills and help the environment, you should consider a solar lease.
  • Do I need to replace my roof before installing solar?
    Solar energy systems can last for 25 to 35 years, and removing and reinstalling them can be costly if you need to replace your roof. If your roof needs maintenance soon, you should complete it before you finish your solar installation.
  • How long will my solar power system last?
    Solar panels are generally very durable and capable of withstanding snow, wind, and hail. The various components of your solar power system will need to be replaced at different times, but your system should continue to generate electricity for 25 to 35 years.
  • How do I choose a solar installer?
    There are a few criteria that everyone should use when choosing a solar installer. Confirm that they are certified, licensed, insured, have relevant experience, and can provide references. Enercon Malaysia is registered with SEDA as RPVSP and RPVI which implies that we are providing high quality services and trusted by local authorities.
  • Should I ask for a solar monitoring system for my solar panels?
    Solar monitoring system can be accessed online whether through a phone app or desktop. Enercon Malaysia provides such services included in the solar system.
  • On what roof materials can solar be installed?
    Solar panels can be installed on almost any kind of roof material and almost any roof structure (flat roof, pitched roof, etc.). Panels are attached to your roof with a racking system. The best racking system for your building depends on how the roof is structured and what type of roofing materials at site. Enercon Malaysia will recommend the racking system most appropriate for your property.
