What a pleasure to deal with Johannes and his team! After researching various options, I decided on Flagship Solar because: • Responsive sales feedback, they addressed my queries promptly and professionally. • In depth product knowledge and understanding of solar energy systems • Pricing was on par and reasonable • Very good references (Google Reviews) • Long track record and reputation gives me assurance that they will be around for after sales support when I need it. And indeed, for installation they were on time, went the extra mile and staff was extremely friendly and knowledgeable. I'll make use of their services again!

I recently had the pleasure of working with Flagship Solar and the team led by Johannes Jacobs for the installation of a Sunsynk system at my home. From the very beginning, I was impressed by the level of professionalism and expertise displayed by Johannes and his team. They arrived on time and immediately got to work, efficiently completing the installation in less time than originally quoted. Not only did they do an excellent job with the installation itself, but they also took great care to keep the work area clean and organized. They were meticulous in their work and paid attention to every detail, ensuring that the system was properly installed and functioning at its best. But perhaps most impressive was the fact that Flagship Solar and Johannes Jacobs did not exceed the budget or ask for any additional fees beyond what was originally quoted. This level of honesty and transparency is not always easy to find in the world of home improvement, and it was greatly appreciated. I highly recommend Flagship Solar and Johannes Jacobs as a credible and trustworthy company. They truly go above and beyond to provide excellent service and deliver top-quality results. Thank you, Flagship Solar, for a job well done!

Case Studies

Vannie Farm

In February of 2021 we were contacted by a client on a small farm in Tesserlaarsdal. They live light on the land, just subsistence farming and growing garlic as a cash crop.

Talisman tool hire Strand, Laignsburg and Kleinmond

In February 2020 We were contacted by Mr. Koos de Villiers of talisman tool-hire in strand. He had recently built a new building for the talisman Tool hire shop and had prepared the new building with basic infrastructure to go off-grid.

How does solar power work?

It all begins with the radiant sun, generously showering its energy onto the panels. This raw energy, however, needs a bit of refinement. Enter the inverter, a superhero in the solar saga. Equipped with a built-in charger, the inverter takes charge controlling the power from the panels and transforming it into a usable form. This versatile wizard can convert it into either AC power for immediate use in your house or DC power to store in a battery for later.

Yes, you read that right – your solar setup can multitask. The inverter ensures that your house can use the solar energy directly or store it in a battery for those cloudy days or nighttime power needs.

Will solar panels generate electricity on cloudy or rainy days?

Solar panels need sunlight to generate electricity, so they will not work at night, after the sun has set, or before sunrise. But there are enough rays that pierce through cloudy weather or rain. The solar energy produced will be less than on sunny days. The type of sun that your panels love is when the panels are cold, just after a rainstorm and the bright light breaks through the clouds.

When you turn your cheeks and you can feel the sun’s rays hit your face, that is when your solar panels are happy.

Does roof orientation matter?

Yes, the orientation and the roof pitch play a vital role in the efficiency of the solar panels. The panels need direct sunlight, thus a north-facing roof is the best option. The thing to consider is shade cast by trees or nearby buildings that can cause a different orientation to be more ideal.

Can you sell back extra electricity generated by your solar panels to your local municipality and is it worth it?

The cost to apply for this and the rate that they pay out is different for each municipality.

The most cost-effective time to apply for this is with your original SSEG registration. If not then the SSEG registration needs to be amended and resubmitted.

Is it worth it to sell back electricity, in general terms most residential homes do not have enough roof space to install extra panels needed to generate electricity over what their consumption is. And the cost and additional meter needed to sell electricity back to the local municipality is substantial and you might not see a return on that investment.

When does it make sense?

When your holiday house has a significant system that can generate spare electricity when you are not there, when nobody is in the house, the electrical consumption is minimal especially if the geyser is switched off. In this situation is makes sense to sell back to the municipality instead of all that extra electricity going wasted.

When can you install my system?

We work on a first come first serve basis, After your deposit has been received you will receive an email from Louis confirming that the deposit has been received and your installation date. In general, our turnaround time is 2 weeks. But when load shedding is at level 6 and we receive a lot of inquiries then that lead time can extend.

The expected lead time will be communicated before you pay your deposit.

How much does solar cost?

Play around with our digital house to determine the size of the system that you need. Once you are happy with the size and everything that you need to run during loadshedding then you can go through the quote process. In less than 5 minutes you should have an answer.

Are you qualified installers?

Yes, we have qualified installers in our team who are registered with the Department of Labour for electricians to sign off your Electrical Certificate of Compliance. They have a Solar Green Card and can sign off the engineering certificate

Everything that you need for your SSEG registration.

We only install brands that are on the City of Cape Town’s approved list of equipment.

Do I need to clean my solar panels and how often?

Solar panels are designed to be self-cleaning in the rain, especially if they have been installed at an angle for the rain to run off.

But if you find that your solar system is not performing as expected then you can check if the panels are dirty in periods with no rain dust can build up or bird poo and fruits falling from trees can dirty the panels, then a good clean with a hose pipe and a clean cloth will do wonders.

My electricity bill is too high can you give me a quote for a solar system... with batteries.

There are two things to note right here, the first is batteries are for convenience and will not decrease your electrical bill. The second thing is, solar panels are a very poor first choice for lowering your electrical bill. As a rule of thumb; for every one dollar you spend to save energy you can save 5 dollars on your utility bill and for every 5 dollars you spend to make electricity – you can make 1 dollar’s worth of electricity.

There are four approaches to lowering your energy usage and bill without the loss of convenience.

  1. Changing to efficient systems
  2. Changing to efficient habits
  3. Changing to non electrical systems
  4. Making your own electricity. A thrifty person will be wise and employ all four methods in the correct balance. The best way to approach the problem is to solve each unique problem with its own unique and appropriate solution.

Will solar panels increase the value of my home?

Yes, especially in South Africa where Loadshedding is an everyday thing more and more buyers are looking for houses that have a solar system installed. If you have to choose between 2 houses all being equal will the house with solar always be the one that is sold first?
