Solar Panels
Solar panels convert sunlight into DC electricity for pumps, inverters, battery systems, and grid-tied installations across South Africa. Bundu Power supplies TUV-certified monocrystalline and polycrystalline modules sized for solar borehole pumps, hybrid inverters, off-grid homes, and commercial arrays — with higher-voltage options that reduce string count on larger systems.
Our Solar Panel Range
How Do Solar Panels Work?
Photovoltaic cells inside each solar panel absorb photons from sunlight and release electrons, producing DC electricity at a defined voltage and wattage (Vmp and Pmax on the spec label). Strings of panels feed MPPT controllers on solar pumps, charge controllers on battery systems, or inverters on grid-tied and hybrid home installations. Output varies with sun angle and cloud cover — peak production occurs around midday, with reduced but useful yield in mornings and afternoons.
Choosing Panels for Your Application
Panel wattage, cell type, and voltage determine how many modules you need and how they connect to the rest of your system. Match panel output to your controller or inverter input limits and oversize slightly on pump applications to account for heat and sub-optimal mounting angles.
Solar Pump Systems
Borehole, pool, and pressure pumps connect panels directly through an MPPT controller — no household inverter required. Size panel wattage to pump demand; hybrid and borehole pumps typically need 30% oversizing for reliable daily output.
Home Inverters & Batteries
Hybrid and off-grid inverters use panel strings to charge batteries and supply loads. Higher-voltage panels reduce the number of modules needed to reach your inverter's MPPT window — simplifying roof layout on residential and commercial installations.
Commercial & Agricultural Arrays
Larger wattage modules suit farm outbuildings, warehouse roofs, and commercial solar projects where maximising yield per square metre and minimising installation labour matters.
Monocrystalline vs. Polycrystalline
Monocrystalline Panels
Made from single-crystal silicon cells, monocrystalline panels offer higher efficiency in a smaller footprint — well suited to limited roof space and applications where every watt per square metre counts.
Polycrystalline Panels
Polycrystalline cells are formed from multiple silicon fragments. They typically cost less per watt and perform reliably on larger ground-mount or barn-roof arrays where space is less constrained.
Quality & Certification
Bundu Power solar panels are CE, UL, and TUV Rheinland certified — tested for rated power output, environmental durability, and long-term safety. Our modules carry a proven track record in off-grid and grid-tied installations worldwide.
