FAQs
How does a Solar PV system work?
Solar panels capture sunlight and convert it into direct current (DC) electricity. The inverter then converts DC into alternating current (AC) for use in your home or business. Any excess energy can be stored in batteries or exported to the grid.
How do solar panels perform on cloudy or rainy days?
Panels still generate power, though at reduced efficiency (10 – 25 %). The system automatically compensates by drawing additional power from the grid or stored energy in the battery.
How does an inverter solar system add value to my property?
The main value lies in the immediate reduction in electricity costs. Additionally, a property with a professionally installed solar system typically attracts a higher resale price and offers greater energy independence.
How much weight can my roof handle with solar PV panels?
The average roof can safely handle between 15 – 20 kg per square metre. Most panels weigh 13 – 15 kg each. For larger installations, it’s best to consult a structural engineer to confirm the roof’s load capacity.
How much maintenance does a solar system require?
Solar PV systems require minimal maintenance. We recommend cleaning panels twice a year and performing an annual inspection to ensure all electrical connections, inverters, and batteries remain in optimal condition.
How important is energy storage (BESS)?
Battery Energy Storage Systems (BESS) are vital for load shifting, backup power, and energy independence. They allow you to store excess solar energy for use at night or during power outages, reducing reliance on the grid.
How long do solar panels last?
Quality solar panels typically last 25 – 30 years with minimal degradation. Performance warranties ensure efficiency remains above 80 % even after two decades of use.
How much can I save on electricity by installing a Solar PV system?
Savings vary by usage and system size, but most clients reduce their electricity bills by 40 – 80 %. The higher your current energy consumption, the greater your potential return.
How much does a Solar PV system cost?
System prices vary depending on size, battery capacity, and components. Residential systems typically range between R80 000 – R300 000, while commercial systems depend on specific energy requirements and load demands.
What warranty options are available for the solar panels?
Our panels include a 12-year OEM (manufacturer) warranty and a 25-year linear performance warranty, ensuring long-term reliability and sustained efficiency.
What kind of return on investment(ROI) can I expect?
Our panels include a 12-year OEM (manufacturer) warranty and a 25-year linear performance warranty, ensuring long-term reliability and sustained efficiency. business and create a better navigation experience.
Can I scale my inverter solar system later?
Yes — all our inverter-based solar systems are fully scalable. The inverter, batteries, and solar panels can be expanded as your energy demand or budget grows.
What kind of return on investment(ROI) can I expect?
Our panels include a 12-year OEM (manufacturer) warranty and a 25-year linear performance warranty, ensuring long-term reliability and sustained efficiency.
Can solar panels be installed on an asbestos roof?
No — installations on asbestos roofs are not legally permissible under any circumstances due to health and safety regulations.
To what percentage can I safely charge my batteries?
Our lithium-ion batteries can safely be charged to 100 %. Built-in battery management systems (BMS) ensure safe operation and optimal performance throughout their lifespan.
Why must I register my system with the municipality (e.g., City of Cape Town)?
Registration ensures that your solar system complies with local grid standards and safety regulations. It also allows the municipality to monitor grid interaction, ensuring fair energy distribution and eligibility for feed-in tariffs, where applicable.
If budget is not a concern, which is the best brand to install?
Premium options such as Sungrow, Victron Energy, and Huawei offer excellent long-term reliability, high efficiency, and comprehensive warranties. The best choice depends on your specific energy goals and system design.
What happens if my inverter fails? Will I be without power?
If the inverter fails, solar generation will temporarily stop. However, clients with battery backup systems will still have power. Our support team provides fast diagnostics and replacement to minimize downtime.
Can I install solar panels if I live in a rental complex?
Yes, but written consent from the property owner or body corporate is required. In many cases, balcony or carport installations or portable solar kits can be used as alternatives.
What are the main benefits of installing a Solar PV system?
Key benefits include lower electricity bills, energy independence, reduced carbon footprint, and increased property value. Over time, solar energy pays for itself through consistent cost savings.
