Solar FAQ

What services does Eigen Energy offer?

We specialise in solar turnkey project. Our in-house team cover design, supply, installation up to successful commission. Whether solar panels, solar inverter, or mounting structure, you can be sure that our components are sourced from the most reputable manufacturers within the solar energy industry.

How does a solar power system work?

Solar panels convert sunlight into electricity that you can use directly for any appliances in your home. If your solar power system generates more energy than you consume, you will be compensated for any excess energy that is exported to the utility grid.

What is the impact of solar power system on my utility bill?

By generating your own solar power, you can significantly reduce your electricity bill. The actual savings depend on your electricity consumption and the size of the solar power system. Get in touch with us to find out exactly how much you could be saving.

How long can solar panels last?

Solar panels are a mature technology that are guaranteed by the manufacturer to operate at least 25 years. All solar panels installed by Eigen Energy come with a minimum 25-year power warranty and 25-year material and workmanship warranty.

Once installed, how do I keep track of the amount of energy generated by my solar power system?

The solar power system includes real-time performance monitoring software with easy access from your computer or mobile device, so you can always keep track of the energy generation.

Does Eigen Energy offer battery storage solutions?

Yes! The battery storage expertise from Eigen Energy can offer various options available to you. However, battery storage for residential systems is not cost-effective in Singapore currently, as any excess energy can be credited to the power grid. This means that battery storage only adds small value to the solar system.

How do I maintain my solar power system?

The maintenance of solar power systems is carried out bi-annually and mostly consists of keeping the solar panels cleaning as well as checking all the electrical connections. Our maintenance package is optional and its cost is determined based on the size of the solar system. The detailed cost estimation will be provided in your free quotation.

What is Solar Photovoltaic (PV)?

There are currently only two types of solar technology that are capable of converting the sun’s energy into a source of power: solar thermal and photovoltaic. While Solar Thermal collectors absorb the sun’s radiation in order to heat a home or water, Solar photovoltaic devices use sunlight to replace or supplement the electricity provided, thereby making it a more viable applicable option on our landscape.

EV Charging Station FAQ

What do I need to know about EV Charging solutions?

Different types of electric vehicle supply equipment (EVSE) provide different speeds of charging. Some charging stations have advanced features such as smart metering, cellular capability and network connectivity, while others are more basic. Globally, the number of electric vehicle networks is increasing to provide a system of publicly accessible charging stations to support the mass adoption of electric vehicles.  With AC and DC charging solutions for every electric vehicle, a modular and adaptable infrastructure makes allowance for customised solutions.

Can any electrician install EV charger?

No. EV chargers may lose their warranty if they  are not installed by an experienced and certified installer to ensure your charger is properly and safely fitted and that it complies with  all regulations.

Do all EVs use the same charger?

All the EVs in Singapore use the same  type of plug for alternate-current charging, and the majority use the same  plug for fast direct-current charging. However, charging may vary in other  countries.

Who can install EV charger?

To  ensure proper installation of the EV chargers, you are required to engage a  Licensed Electrical Worker (LEW) to certify the fitness of the installation.  This is included in the Eigen installation service.

can I install my EV charger outdoors?

Electric vehicle charging stations are  flexible devices that can be installed outdoors. The port where you plug in the cord to your  car’s battery is designed to flush water and drain when charging an  EV. Similarly, the cord itself is made to repel water, and once your  charging system is connected to your car’s battery port, a watertight seal is  created, ensuring a safe and reliable charge, even in the harshest of  conditions.

How an EV charger works?

There are two types of electrical currents important when itcomes to EV charging: Alternating Current (AC) and Direct Current (DC). The electricity that comes from the grid and is accessiblethrough the domestic sockets in your home or office is always AC, while the electricity that is stored in batteries or used in theactual power circuitry inside electric devices is DC. For an AC charger, whenyou plug your EV into the socket, it will always receive alternating current.However, because batteries store direct current, a conversion will take placeinside your EV through your car’s converter. On the other hand, a DC charger converts the AC powerbefore it enters your vehicle battery, bypassing the car’s converter, therebyallowing for faster charging.

What EV charger do I need?

An EV  charger should be selected based on the following factors: your EV’s  recommended amperage or current, the charging level that works with your car,  and your home's available electrical capacity.

What EV charger to buy?

EV charging is divided into 3 levels; level 1,  level 2, and level 3. The higher the charging level, the higher the power  output and the faster it will charge your electric car. The level of EV  charging you can have is subjected to your building’s available capacity.

How to install an EV charger at home?

The easiest way to find an EV charging  installer is to use an installer recommended by your EV charger brand. The  good news is: Eigen is a listed preferred installer for most EV charger  brands in Singapore.
