LDK Solar Modules
LDK4 Supply LDK Solar Modules Our systems consist of PV modules which use advanced semiconductor technology that offers enhanced suitability for affordable and efficient solar power systems. It ascertains the lowest carbon emission and maximum sunlight absorption. We offer proven products for integrated solar solutions, including modules and utility-scale photovoltaic (PV) systems. Our modules are mainly of two types: multicrystalline & Monocrystalline.
Solar Cells
Our Supplied solar cells made by LDK are 5 and 6-inch, high-output cells with a silicon nitride anti-reflection coating and BSF. (101.5x101.5mm - 125.50x125.50mm - 150x150mm) .
Solar Batteries
We provide off-grid systems with solar (Deep Cycle) batteries which are a key component in any renewable energy system. It acts as the energy bank and provides the necessary backup for the system in absence of primary power source.
Commercial & Industrial Systems
The solar power systems we provide for commercial establishments are designed to maximize value for customers with large facilities. Our systems are suitable for both rooftop and ground-mounted commercial installations. One of the most important aspects of our systems is the optimum usage of space in your premises. Large systems can be integrated with your energy sources through a common grid or a backup bank.
Solar Charge Controller
LDK4 produces highly efficient solar charge controller allowing total customization to support individual off-grid systems. It uses high-end technology to ensure efficient charging of the battery bank and prevent overcharging thus, elongating the battery life. Our charge controllers are programmed to maintain a discharge rate of 60% which is in accordance to the requirement of Infrastructure Development Company Limited (IDCOL).
Upon individual demand, we also provide maximum power point tracking (MPPT) charge controllers that is able to convert excess voltage into amperage. Solar panels can deliver far more voltage than is required to charge the batteries. By converting the excess voltage into amps, the charge voltage can be kept at an optimal level while the time required to fully charge the batteries is reduced. Lower voltage in the wires running from the solar panels to the charge controller results in higher energy loss in the wires than higher voltage.
All the charge controllers included in our solar power systems are designed to prevent reverse-current flow and can control voltage ranging within 12-100V.
Solar Inverter
Our systems consist of highly reliable DC-AC solar inverters both of pure sine wave and modified sine wave. The embedded technology ensures operation at the highest efficiency at all times, independently of string length and temperature.
LDK4’s inverters are designed to draw energy from battery, manage the battery charge, and export excess energy to the utility grid. These inverters are capable of supplying AC energy to selected loads during a utility outage. The output goes to zero volts for a time before switching positive or negative. It is simple and low cost and is compatible with most electronic devices, except for sensitive or specialized equipment.
We recommend grid-tie inverters for customers requiring large systems. On-grid (grid-tie) systems do not have a battery bank and converts DC-AC directly from solar panels. The electricity gained by the solar modules travel directly through the inverter into the common grid and acts as a secondary grid connection.
