How to choose solar EV charger

The solar EV charger is a helpful product for electric car owners. Many car owners have problems charging their EVs, so it’s cool to be able to charge them at home with free and clean solar energy. However, in practice, it is not as easy as it sounds. This guide can help you choose the correct solar EV charger for your electric vehicle.

What Is a solar EV charger?

Solar EV chargers are devices that can charge electric vehicles using solar energy. It is well known that electricity from solar energy is much cheaper than the grid and more practical in times of energy scarcity. Solar EV chargers usually consist of the following components:

• Solar panels: Solar panels consist of photovoltaic (PV) cells, which convert solar light into DC electricity.

• Inverter: Solar systems generate DC power, while electric vehicles need AC power to charge. An inverter converts DC to AC electricity, which is necessary for fueling an electric vehicle. In dedicated solar chargers, the inverter comes integrated in the electric vehicle supply equipment.

• Battery storage system: A battery storage system ensures that your solar energy doesn’t go to waste. When your vehicle is disconnected, the system continues to store the energy your solar panels produce. When you reconnect your vehicle, it can charge off the power stored throughout the day.

• Electric car charger: It consists of an interface, software, electrical conductors, and protocols that allow for the safe delivery of electricity into your vehicle’s battery.

Types of solar EV charger

Suppose you own an electric car and are interested in charging it with solar power. In that case, you can choose to install an integrated solar charging station or add an inverter and charger to your existing home solar system.

Integrated Solutions

An integrated solar charger is a solution that combines solar panels, an inverter and a battery storage system that requires no additional setup or wiring other than installation. For example, NASN’s Solar EV charger system is a solution for your choice.

Separate Solutions

Separate installation is an excellent choice if your home already operates on a solar power system but you don’t yet have an Electric car charger. You need to choose the suitable Electric car charger and inverter to suit your electric car charging, but you need the cooperation of professionals.

How to choose a solar EV charger

There are several factors to consider before you decide to choose a solar EV charger:

1: Determine how many kWh you need for your car for your driving habits.

The amount of power an electric vehicle requires depends on several variables, including:

The type of EV you choose;

How much you drive;

B attery system  you incorporate into your solar PV system .

2: Figure out how many solar panels you need to make those kWh according to the solar.

The number of solar panels you will need will largely depend on how much you drive daily, weekly, or monthly.To calculate the number of solar panels, you will need to figure out how much energy your electric vehicle will require per day. Consider the following equation:

The average drives about 1,100 miles per month. No matter what type of car we drive, reducing our transportation needs should prioritize all people worried about their overall environmental impact. Let's imagine a family that drives less than the national average - about 600 miles per month, or 20 miles per day. The Tesla Mode 3 mentioned above requires about 26 kWh for every 100 miles.Based on the calculation mentioned above, this amounts to:

26 kWh /100 miles × 20 miles/day ÷ 100 = 5.2kWh/day

Assuming you receive around 5 hours of direct sunlight on your solar panels each day, a premium solar panel could produce about 1.5kWh per day. So, you would need at least four 290 watt panels to give you the power you need to power your EV autonomously, without help from the grid. The more you drive, the more you need!

3: Figure out the battery capacity you require.

Besides a solar panel, you will need a way to store the energy produced by your panels. This storage is necessary because most families rely on charging their EV overnight when the sun is not shining. There are many home battery storage options  on the market today. For example, Portable emergency EV charger system is one of the best solutions on the market for EVs as it stores up to 15 kWh of energy. This capacity should be enough to help you meet your daily mileage requirements.

4: Check with solar EV charger manufacturer on the configuration.

Based on your solar pane and battery capacity, NASN will provide you a complete solution for your EVs. Welcome inquiry.

Charging Time

Level 1 chargers take about 20 hours to fully charge, level 2 chargers take 8 to 10 hours, and level 3 chargers can reach about an hour. It is recommended to choose from Level 2 chargers and Level 3 chargers, although you need to pay more but from the use of experience and long-term considerations are better choices.

Off-Grid Needs

The solar electric car charging options currently on the market have varying degrees of reliance on grid energy.It would be best if you made your choice according to your needs.

Expertise

Expertise is relevant to choosing between an integrated or a separate installation. If you’re knowledgeable about solar inverters and how to set up a solar power system for optimum use, installing your inverter separately may allow you better control over your energy distribution. An integrated installation may be a better choice if you want to reduce installation time and save money.
