According to Rein Snoeck Henkemans, CEO of Alumo Energy, the root of most problems is simple: a lack of accurate information before purchase.
“Homeowners often focus on the number of panels rather than total energy output,” Henkemans explains. “Two systems might have the same number of panels, but if the wattage differs, the electricity generated also differs.”
Another trap is chasing the cheapest option. Low-cost systems frequently use substandard components, come with weak warranties, and are installed by inexperienced teams. “They might work for a few months, but they rarely last. Going cheap can cost far more in the long run than choosing quality from the start.”
It is paramount to check that panels and inverters come from reputable manufacturers and that surge protection is included on both AC and DC sides. Certification is essential - uncertified systems can cause insurance issues or even require removal. It’s a good idea to check that the system is on the approved NRS list before making a purchase.
A vague or incomplete quote is also a warning sign. “If it doesn’t clearly list panels, batteries, cables, or protection measures, walk away. In addition, check online reviews or ask for references. Ultimately, you’re trusting this company with your energy independence. Make sure they’re credible.”
Alumo begins every project with a site visit to assess energy needs and budget. “A system that’s too small will fail during outages, while an oversized system wastes money. For businesses, Alumo provides detailed design packs that show exactly how power flows through the system - critical for safety and performance.
Environmental and structural factors also matter. Even slight shading on a single panel can reduce output across the array. Roof type plays a role: flat roofs may require tilt-up frames, while slate increases leak risk. Timing energy use matters too. If most electricity is used at night, a small battery won’t give good returns. Using timers to shift consumption to daylight makes a big difference.
Unlike many providers who outsource, Alumo installs all systems with its own trained teams. “We use self-extinguishing trunking to prevent fires and high-quality surge protection to protect appliances. Every installation is reviewed by a quality control manager.”
Support continues long after installation. Alumo provides 24/7 assistance and free swap-outs for faulty inverters or batteries under warranty. Homes receive a six-month check-up and annual maintenance, while commercial clients get schedules tailored to system size and location.
“Don’t chase the cheapest option,” Henkemans warns. “If it seems too good to be true, it probably is. Work with a company that designs systems to meet your exact needs and has a proven track record.”
For South African households and businesses, going solar isn’t just about reducing bills - it’s about reclaiming control over their energy needs. Partnering with Alumo Energy means investing in reliability, safety, and long-term peace of mind. With the right system, solar is more than a purchase: it’s freedom from blackouts and unpredictable tariffs, delivered reliably. DM
