Solar panels generate electricity even on cloudy days or during periods of low sunlight, though at a reduced efficiency. At night, they do not produce electricity. Instead, power is supplied from stored energy in batteries charged during daylight hours.

Solar photovoltaic (PV) panels convert solar energy into direct current (DC) electricity through the photovoltaic effect. This electricity can either be stored in batteries for later use or, if the system is equipped with a solar inverter, the electricity is converted from DC to alternating current (AC), allowing it to power typical household AC appliances, such as standard televisions, fans, and refrigerators.

By harnessing solar energy, a sustainable and emission-free power source, we reduce our reliance on non-renewable fossil fuels, thereby protecting the environment. This shift improves air and water quality, fostering a healthier environment.

Solar panels can overheat in extreme temperatures, impacting their performance. However, proper installation and ventilation can help mitigate this risk.

Sun King solar panels are built to last 10 years for solar lanterns(such as Booms) and Smaller Home Systems(such as the Home 200x or 500x), and up to 25 years for Solar Inverter Systems(such as the Powerplay or Powerhub). With proper care, they can often last even longer.

Maintenance tips:

1. Clean panels regularly with a soft cloth or sponge to remove dust, dirt, or debris.
2. Check connections and wiring periodically for any signs of wear or damage.
3. Ensure proper ventilation around panels to prevent overheating.

If you suspect your solar panel needs replacing, please escalate the issue through the Inverter Customer Support Portal or visit the nearest Sun King shop. Do not attempt to disconnect or replace the panel yourself, as this could be unsafe. Sun King will guide you through the proper replacement process

Yes! Even during load-shedding, your solar panels can charge your inverter during the day.

Our PowerPlay and PowerHub hybrid systems use both solar energy and the grid, so you can keep your devices running with stored battery power or sunlight.

Sun King’s solar products can be found in over 40 countries around the globe, across Africa, Asia, Europe, and Latin America.

Incorporated in 2009, Sun King has been in operation for over 15 years.

Sun King is on a mission to power access to brighter lives. Sun King designs, distributes, installs, and finances solar home energy products for the 1.8 billion people currently living without reliable energy access.

In Zambia, most households use prepaid electricity meters, which require you to purchase electricity credits in advance. Your consumption is tracked in units, and each unit has a cost determined by your electricity provider’s tariff.

To monitor your usage:

1. Check your meter regularly to see how many units you have remaining.
2. Keep your purchase slips to track how many units you buy each month and how long they last.

This will help you estimate your electricity costs and plan your purchases, ensuring you never run out of power unexpectedly

Installing a Sun King solar inverter system, such as our PowerPlay Pro and PowerHub, can significantly reduce your electricity bills by using solar energy. These systems are hybrid, meaning they can draw power from both solar and the grid. The systems can also be set to automatically prioritise solar charging over grid electricity for maximum savings.

Yes. Your prepaid meter continues to operate as usual. It will only record the electricity you draw from the grid (ZESCO), while solar-generated power bypasses the meter.

At Sun King, we help you find the right solar inverter solution by first understanding your energy needs and usage patterns.

Sun King’s range of solar inverter systems such as our PowerHub and PowerPlay systems, comprise solar panels, LFP battery storage, and one or more hybrid solar inverters. A solar inverter plays a crucial role in a solar energy system, acting as a bridge between the solar panels, the battery, and the building or facility’s electrical infrastructure. It converts direct current (DC) electricity, generated by solar panels, into alternating current (AC) electricity. This AC electricity is compatible with the electrical grid and can power standard household appliances, ranging from standard televisions, computers, and refrigerators, as well as other devices. Additionally, hybrid solar inverters can draw power from both solar panels and the electrical grid, ensuring a reliable power supply.

The solar panels harness sunlight and convert it into electrical energy. The panel-generated DC energy is then transformed into AC electricity by the inverter, making it suitable for everyday household use. Lastly, the Lithium-Ion Phosphate (LFP) battery stores not only solar-generated energy but also energy from the grid, ensuring that appliances can be powered continuously, even when the sun isn’t shining.

Each solar inverter system is carefully designed to meet the needs of different households and businesses. We offer custom packages for people whose needs aren’t met by our standard bundles, and each system can be expanded post-purchase.

Yes. To operate independently of the grid, a system must include battery storage to hold surplus energy when sunlight is unavailable. Sun King provides off-grid solutions equipped with battery storage, catering to areas with no access to the grid.

The maximum power output and battery capacity of our inverter systems differ from system to system. The runtime depends on the appliances connected and individual usage. During the load-sizing process, Sun King provides clear guidance on the types and number of appliances each system can support, helping you choose the right fit for your needs.

Each solar inverter system is carefully designed to meet the needs of different households and businesses. We offer custom packages for people whose needs aren’t met by our standard bundles. Many systems can be expanded post-purchase to include additional solar inverters, batteries, or solar panels. Please contact us for more details.

The durability of a solar inverter system is influenced by its quality, how it’s used, and the maintenance it receives. Sun King provides a three-year warranty for solar inverter systems. Solar panels have a life expectancy of up to 25 years. The lifespan of the inverter is dependent on proper maintenance and care. The battery is expected to last up to ten years under normal working conditions.

Through regular maintenance and prompt repairs, the lifespan of the solar inverter system can be extended.

If you reside in a windy area, rest assured that Sun King’s installations are designed to withstand such conditions. Our systems are installed by trained and qualified professionals who use proper installation techniques and secure mounting systems. This ensures that the panels remain stable and secure, even in high winds. Additionally, wind can benefit the system by cooling the panels, which can potentially increase their efficiency. Sun King prioritises the resilience and performance of your solar installation in all weather conditions.

Solar panels can generate electricity even in indirect sunlight. While bright sunlight optimises performance, panels still produce power on cloudy days.

A suitable roof should have adequate space, strong structure, minimal shading, and a favourable orientation towards the sun. This also depends on the kind of solar solution you’re looking to buy. Sun King will assess your roof’s suitability during the pre-purchase consultation.

For larger solar panels like the ones used to power inverter systems, if your roof is in good condition, the panels can typically be installed without replacing it. In some cases, roof repairs or reinforcement may be necessary to support the weight of solar panels.

Solar home systems, such as the HomePlus and Home 500X, come with smaller panels which are less likely to require specific types of roofs or a certain level of robustness.

Solar installations in apartment buildings are possible, often through shared or community solar arrangements. Consultation with building management, landlords if renting, and compliance with local regulations is essential.

Installing solar panels in a rented building will require permission from the landlord or property management. Portable or removable solar solutions like Sun King’s solar home systems may be good options for renters.

Yes, Sun King conducts thorough site visits to assess various factors such as roof orientation, shading, structural integrity, and the power requirements of the appliances to be powered.

Preparation requirements can vary. The Sun King team will arrange a call with you before their visit. In most cases, you only need to agree on a date and time for the delivery and installation. All necessary details will be explained during the call prior to the team’s visit.

Before installation, the products will be delivered to your building or home. On installation day, Sun King’s technicians will mount panels, connect the inverter, and integrate the system with the circuits powering your building. They conduct tests and provide guidance on system operation, payment, and maintenance.
