How to calculate solar panel requirements based on your EV.

Imagine cutting down your electricity bills while ensuring a greener planet—solar-powered EV charging makes this a reality. As more Malaysians embrace electric vehicles, their pairing with solar energy creates a sustainable and cost-effective solution. In this article, we will look at exactly how solar-powered EV charging works, the financial and environmental benefits of such a system, and most importantly how to calculate solar panel requirements for your EV.

How Solar-Powered EV Charging Works at Home

Solar panel systems for EV charging often have photovoltaic (PV) panels that convert sunlight to electricity, an inverter to convert DC to AC, and optional energy storage in batteries. The system ranges in size, with 5 kW meeting basic needs and 10 kW meeting higher demands, to ensure a constant supply of sustainable energy for EV charging purposes. Battery storage helps store excess solar energy that can be used when solar power is not available.

Things to Consider Before Installing solar panels.

Property Type

Solar panels can only be installed on landed properties, and these units require their roof access.

Electricity Usage

 Solar will work out cheaper if your monthly electricity bill exceeds RM200.

Location and Regulations

Check with local authorities to see whether they support initiatives like the NEM scheme. Not all states support such initiatives. Check to see whether the solar radiation in your location is viable for solar.

Roof Condition

Your roof has to be in good condition and installed correctly to receive maximum solar energy capture as the angle of solar radiation received of the panel is critical in determining the efficiency of the received energy.

Inclusion of battery storage

Its important that a battery storage is installed with the solar paneling system as it will store the excess energy for later use. This is mandatory for those who charge their EV vehicles during the night

Choosing the Right Installer

Choose an installer such as Energi Elite, known for its strong reputation and rave reviews, to ensure high quality in service and reliability in the equipment.

In this example, we’ll take the BYD Seal as its among one of the top selling models of EV for BYD from within the recent monthly JPJ registration EV vehicles.

Step 1: Energy Efficiency of the BYD SEAL

• The BYD SEAL’s efficiency is 12.7 kWh/100 km or 0.127 kWh/km.

Step 2: Daily Distance

Lowyat users claim mileage of up to 550 km per week.

• Taking the average commute of a Malaysian driver’s annual mileage, we can get 77km /daily.

Step 3: Calculate Daily Energy Consumption

• Multiply the energy consumption per kilometer by the daily distance:

Step 4: Determine Required Solar Capacity

• Taking the average peak hour in Malaysia, which is between 4-6 hours, we can calculate the solar capacity needed to generate the daily energy:

Step 5: Solar Panel Capacity

• Take an example of a 410W (or 0.41 kW) solar panel.

Step 6: Calculate the Number of Solar Panels

• Divide the total required solar capacity by the capacity of a single solar panel:

For a daily driving distance of 77 km, you would need 4 solar panels (each rated at 410W) to fully charge a BYD SEAL, assuming that it reached a daily of 5 hours of peak sun hours.

Investment Costs for Solar-Powered EV Charging

Initial investment

Setting up a solar panel system to charge EVs requires, on average, a capital investment of MYR 40,000 to MYR 50,000, depending on the chosen capacity and quality. This encompasses the cost of the solar panels, the inverters, the installation fees, and probably battery storage if wanted.

Maintenance

While solar panel systems generally need little maintenance, there may be some occasional cleaning or inspection fees, or inverter replacement, for instance—this type of component can last for about 10-15 years.

Battery Storage

Adding the battery storage to hold the sun’s energy for charging at night will greatly raise initial costs. Battery storage can run an additional MYR 15,000 to MYR 25,000 or more, depending on capacity and type.

Why Solar-Powered EV Charging is Worth It

Electricity Bills Savings

A house owner installed a solar system in 2019 for RM31,000. Five years down the road, he is making savings worth RM300 to RM400 each month and has another five years to reach payback. This is an indication of huge savings with solar-powered EV chargers.

Government Incentives: SolaRIS Rebate for Solar-Powered EV Charging

According to a recent announcement by the Deputy Prime Minister and Minister of Energy Transition and Water Transformation, the Malaysian government has introduced the Solar for Rakyat Incentive Scheme (SolaRIS). This initiative is designed to encourage the installation of solar PV systems for domestic consumers. It offers a one-time cash rebate of RM1,000 per kWac, up to a maximum of RM4,000, for eligible NEM Rakyat customers.

The rebate is available on a first-come, first-served basis from 1 April 2024 until 31 December 2024. Installations must be commissioned by 31 March 2025 to qualify. This incentive significantly reduces initial costs, making solar-powered EV charging a more financially viable option for homeowners seeking to utilize clean energy.

Net Energy Metering

Excess electricity generated by solar panels can be fed back into the grid through a net energy metering scheme to earn credits that further offset one’s electricity bill.

Environmental Impact

The above reduces the carbon footprint to the extent possible from fossil fuels in EV charging, making the whole process of energy consumption sustainable to achieve the environmentally set goals regarding reducing GHG emissions.

Energy Independence

There is a level of energy independence from the grid offered by solar-powered EV charging, especially where the cost of electricity from that grid is already high or the electricity supply is unreliable. This can be especially good in ensuring stable and predictable energy costs.

Return on Investment (ROI)

Because it offers considerable savings in monthly electricity bills, it has a payback period of just five years for an initial solar investment. Even after return on investment, owners continue benefiting from reduced energy expenses that translate into long-term financial savings.
