Navigating the Solar Market

Choosing the Right Backup Power Solution for Long-term Grid Independence

The rocketing costs of electricity, load shedding & a collapsing Eskom wreak havoc at both our homes and workplaces. But before you rush into purchasing a power solution, you need to take a considered and long-term view of how to get yourself as close to grid independence as possible, from the outset.

Any money spent on an unsuitable back-up solution today detracts from your ultimate objective of greater grid-independence and self-sufficiency. Don’t be lured into the many cheap solutions being punted
on the market by drop-and-go shippers and be especially wary of the many unqualified fly-by-nights who have popped up in a bid to cash-in on the solar boom. 

The installation and management of solar PV systems is a complex and highly skilled undertaking sitting on top of your most expensive asset – your home or business, so you don’t want to get it wrong.


Expert Solar Installation

Avoiding Common Mistakes for Safe and Efficient Systems

With so many new solar products and changing technology, it’s very difficult to know what the right system and tech is for your needs now, and in future. Every component in your system needs to be compatible – not every inverter is compatible with every battery, and even different makes of municipal electricity meters can prove problematic. Deal with an expert who knows their stuff and has the track record, deep technical expertise and perfect installations over the years to walk the journey with you.

A quick look at Hello Peter and the proliferation of new contractors that have suddenly sprung up trying to cash in on the solar boom are evidence that there are plenty of very bad deals out there, with lousy outdated technology and even more questionable installation and safety standards. No one becomes a solar specialist in a few months! Work with qualified professionals and get it right, first time.

Even the best equipment will fail and perform badly if they are not installed and programmed correctly. The consequence of a non-compliant installation is poor system performance, premature battery failures and in the worst cases, an outright safety/fire hazard. And if the worst should happen, any insurance claim will be rejected due to non-compliance.

Perfect Installations

Our driving business philosophy is summed up in two words – Perfect Installations, with over 13 500+ perfect solar installations completed as at the end of 2022.

3 Steps to Achieve Grid Independence

The journey to grid independence is a big and important decision and you need to be sure that the steps you take today are right for your needs down the line. 

Schedule your obligation-free consultation and comprehensive assessment to get off the grid, step-by-step, with a solar partner that walks the journey with you, every step of the way. 

Book a Free site visit & consultation

A thorough load analysis, site assessment and consultation is a must to work out the right fit for your needs based on day/night usage, selective loads or peak demands and your long term plans, all of which need to be factored into your solar PV solution. We can tell you how much your system will generate and what you can expect with absolute confidence – because we’ve done the proper groundwork upfront with you.

System design & implementation

Based on your site assessment and energy audit, we’ll design a scalable, quality solar PV hybrid solution that takes care of your immediate needs for back-up power during load shedding and power failures and allows you to scale up in future to maximum self-generation by adding solar panels and additional battery storage if needed. Not all inverters offer this scalable functionality so work with a solar partner who is experienced in this field.

‘always on’ power

When the lights do go out in your suburb, you won’t even know about it. You take back control and ensure the security of your electricity supply, your productivity, your safety and costs for your home and business with reliable, renewable solar performance.
