How many solar panels does it take to charge an electric car?
In Australia, many electric cars require about 14 to 18 kWh of electricity to drive 500km. So now we need to decide how far the electric car can travel on one charge. Let’s say we set a distance that this particular electric car can travel using two scenarios;
For example A, the electricity required to travel 300km by electric car is between 42 and 54kWh of electricity depending on the model of EV vehicle.
For example B, the electricity required to travel the 500km by the electric car is between 70 and 90kWh of electricity depending on the model of EV vehicle.If you now use the LG output calculator to work out how many solar panels you need to charge an electric car and you will see that in order to generate 48kWh (which means the car can travel 300km each day) let’s say in Perth in December, one will need a 6.6kW (6600 Watts) system.
I have to thank Tesla for bringing the electric car to the forefront of many people. Lots of other car manufacturers are now moving along and offering electric vehicles.
How good is it that if you can actually then charge your electric vehicle out of a solar system from the roof on your house.
If you are looking at an electric vehicle your solar system possibly needs six-kilowatt size for the house and then another four or five kilowatts of solar system for the car, so you will need a larger system. Maybe look at a battery as well.
Our LG energy specialists can very much help you to look at what combo you would need.
If you've got an electric car there is definitely a solar system that needs to go on your roof to fuel your car so you possibly need a five to six-kilowatt system for your house and you then need another five kilowatts for the cars you might need a battery.
Now your roof space only has a certain size so a high efficient panel like the LG solar panels will certainly give you a solution that allows you to have a car, look after your house and have the lowest possible electricity bill.So thank you very much for joining us here at the LG Energy website. We have frequently asked questions and all the answers. We have beginners guides,videos from dealers we have output calculators so you can actually see what happens in your area with the solar system how much it will generate so please go onto the website do your research if you're looking into solar LG is the way to go
How long do electric car batteries last?
With electric batteries for electric vehicles they have a degrading factor, what this means is each year the battery will perform a little less, and usually, by the time a battery only outputs after full recharge 60% of the initial capacity, it is time to change the electric car battery.
How long it takes to reach the time when this critical 60% threshold on your electric vehicle car battery has arrived, depends on a multitude of factors, such as environmental conditions.
For example, electric car batteries do not like heat too much, so if you live in regional South Australia where temperatures on the ground can sometimes get up to 49 degrees Celsius in peak summer and you park your electric car outside every day, then your electric vehicle battery potentially will not last as long, as if you park the electric car (EV) every day in a cool underground car park in the Sydney CBD.
How long does it take to charge an electric vehicle and what is the cost?
As electric vehicles evolve and more and more manufacturers add electric cars to their normal car offering, the size of batteries and the driving range between electric car charging also starts to change considerably. In other words, there is no clear hourly number that one can plug from the air to describe the time it takes to charge an electric car (EV).
In general for example Tesla advises that the charge time via a standard car charger can be between as little as one hour to top up the battery, and as long as a day – meaning a full 12 hours if the battery was very much exhausted.
The Nissan Leaf – as it is a light electric vehicle with a smaller EV battery to be charged, offers as advice a charge period in Australian conditions of between 4 and 8 hours - again depending on the electric battery discharge rate and state of charge when the car gets connected to the charging station.
In regard to the cost of a charge, many electric cars claim they need between 12 and 18kWh of electricity to travel 100km. So if this electricity is now coming out of a renewable energy source, such as an LG high quality residential solar system, then the cost of running the electric car will be very low.
If the car would simply be charged via the grid and it needed 16 kWh to travel 100km and the local kWh cost per 1 kWh is 30 cents then the electricity cost for a 100km EV trip would be $4,80 (16 x $0.30). This would be at least half the cost of the fuel required to power a conventional petrol vehicle.
Why choose LG Solar Panels?
Not all solar panels are built the same. When you purchase solar panels from LG Solar you are investing in a product backed by years of experience and manufactured with the help of stringent research and testing standards.
With oil prices still steadily rising and global warming a growing issue electric vehicles and hybrid cars are becoming a mainstream option for consumers. Consumers wanting to save some money and also reduce greenhouse gases are opting for them.
These cars use rechargeable batteries and these batteries can be powered by solar panels. Therefore solar panels can have a massive impact in the reduction of the release of greenhouse gases.read more
Our solar modules are made with slim and durable glass, designed to be light in weight while also being able to withstand heavy loads up to 6000 Pa front load. LG`s rear load rating of 5400 Pa means our panels are able to withstand winds up to 345km/hr. (Cyclone Katrina that devastated New Orleans was 270km/hr).
The module frame colour is an attractive black and is anodized to increase durability and minimise damage from rain and salty sea wind over time. LG panels are warrantied for 12 years against salt mist corrosion right down to the waterline.read more
It is advisable to organise some maintenance inspections every few years to make sure that all parts of your solar electric power system are operating correctly. With a tilt angle of 10 degrees or greater solar panels are self cleaning. If you install panels onto a flat roof without panel tilts you will need to hose down your panels every couple of months.
Make sure that when you purchase your solar system, your dealer includes a solar monitoring system to cross check your actual output against warrantied performance rates. Good monitors will input daily weather data for an accurate daily analysis. They could also enable you to monitor your daily consumption of power so you can compare solar power capacity against usage to maximise your solar power usage and minimise unused solar power going back to the grid. If there is any drop in performance organise an inspection by your solar installer.read more
