Where is the best solar charging

Can You charge an EV with rooftop solar?

One of the big drawcards for those with rooftop solar is the ability to charge an EV using your own power. Charging with your solar-generated electricity can essentially eliminate the ‘fuel’ cost of an EV. However, this is not always as easy as it sounds in practice.

How much solar power do you need to charge an EV?

In contrast, an average household with regular EV charging may require 10 to 12kW of solar power or 24 to 28 solar panels. This is around 50% bigger than the average solar size. However, solar EV charging can be easily achieved in some cases using a much smaller solar system (6 to 8kW) if the charger is a low-power 10 or 15A portable charger.

Can I use a solar inverter with a Smart EV charger?

If this is the case, using an EV charger from the same manufacturer as your solar inverter makes sense and easily lets you set up a smart EV charger. Likewise, if you have a hybrid (battery storage) system, you will already have an energy meter, so these are also compatible with smart EV charging.

Can You charge a solar EV with a Level 2 charger?

However, as explained later, solar EV charging using a more powerful 7kW (level 2) charger can be tricky, even with a much larger solar system. The problem arises as the solar will often not generate enough to cover a level 2 charger at full power during cloudy or bad weather.

Can a hybrid inverter charge a car directly from solar?

Hybrid inverters have been used to charge high-voltage batteries, like those used in EVs, for many years directly from solar. The main benefit of the direct DC charging approach is bypassing the home's AC infrastructure and the limitations of the car's onboard charger, enhancing both efficiency and charging speed.

Can You charge an EV using a home off-grid Solar System?

Charging an EV using a typical home off-grid solar system can be challenging for several reasons, the most obvious being the limited amount of energy available during the day, especially during poor weather. Another problem lies in the limited EV charging window, as the most effective time to charge an EV is directly from solar.
