Frequently asked questions

We now have an FAQ list that we hope will help you answer some of the more common ones.

It depends on the setup. If you want to use Powerwall as a backup only system, then you don’t need the inverter, but if you’re adding panels you need solar inverter as power does not connect to the panels.

Of course, yes. Depends on how much you want to spend on Panels and extra Powerwalls if that’s needed. A lot of people in Australia, New Zealand and USA run off grid on Powerwall. We have one installation in Kommejtie Cape Town fully off grid on Powerwall.

It’s not a matter of how many panels, you can use 2 panels and it will take you 6 months to charge. It’s about how fast you want to charge and what is your current load consumption. Remember power going in the battery is solar power produced, minus solar power directly consumed or used by the loads and balance is what goes in the battery. We calculate that on average there is only 5hrs of sunshine so we need to charge Power wall in 4-5hrs.

Yes, it is well worth the cost. There is no battery system that comes close to Powerwall. Even if you do a comparison on cost per kWh, Powerwall works out cheaper. Just consider the benefits, 10yr guarantee plus 20yr 80% linear output warranty. Meaning in 20yrs, you should still get 80% out of the Powerwall. No other battery manufacture offers that. Plus, your battery is always updated with Tesla OTU ( over the wire updates ) so basically you always have the latest software on the battery adapted to your battery working conditions. Also with liquid thermal control, your Powerwall always runs at optimal temperature, no matter the weather.

Rushni Gamildien

Smiling all the way during load shedding. Thank you John and team for the quick installation, friendly team and an awesome product!. A bigger thank you to John for his professional after sales service. John is ready to help any time of the day and night which makes the transition so much easier. Highly recommended.

Pri Noah

“My neighbor told me about Smartenergy after he had solar panels installed them. He told me they were the best SA, and now that I’ve gone through the process with them, I couldn’t agree more! Great job, Smartenergy -- even better service and amazing prices!”

Debbie Shaw

Guys did a fantastic job for me installed a 6kw grid tied system. They sorted out my applications with the city to allow me to feed electricity back to the grid and get paid for it!! Defiantly recommend John and his team. Professional and efficient!

Timothy Coogan

“I’m happy with the customer service Specially with the Team Leader Victor, he is very helpfully, nice Easy to talk to and every time I call him he is humble and answer all my questions I have.”

Mrs. Pierce Smart

“Best Solar Company, very professional and efficient All questions were answered, and all phone calls are getting returned in minutes. Had them install my system in 2014 Best choice I made.”

Mr. Mackenzie

“Incredible service, great pricing, and super fast installation. Having had a brand new roof installed we were particularly nervous on which solar company to appoint and carry out the installation. They completed EVERYTHING in one day and after multiple storms as a stress test, not a single leak or any major problems. We were very impressed. Highly recommended.”

Tim and Brenda

“The technicians were accommodating. They answered all our questions and worked with our schedule. Our roofer requested for a consultation with the technicians while he was working on our new roof to ensure that our warranty for the new roof will not be voided when the solar panels are installed. They coordinated with our roofer well ”

Michelle Harvey

“They made the process of getting solar panels very easy. I don't think about it now, except that I have a much lighter conscience about our pollution footprint. Anyone with a sunny roof should at least call them and check out how much it would cost for their specific situation.’’

Warren and Mikayla

“Wonderful company. It was very simple, straightforward and fast. They have stayed in contact, monitoring my system since 2013. Very happy with how they installed my solar system.’’

Frank Zeeman

“The installation of my two Tesla batteries was on time, on budget and very neatly done. They took care of the paperwork, leaving me to enjoy my investment. Well done!’’

Dan MacDonald

“Installed 30 Canadian solar panels with SolarEdge inverter in August 2014. Smart Energy SA was great all the way through the process. They were quick to respond with all communications. They quickly got the permission to install from the City of Cape Town. The price was competitive. The installation was very quick (took 2 days). The only issue was they had 3 optimizers that failed, but the team quickly replaced them the next day. The system has worked great without any problems!’’
