Solar Home Lighting Systems
Sunsoko offers Solar Home Lighting Systems. These are the most efficient and reliable stand-alone home lighting DC and AC systems. Solar stand-alone systems are made up of interconnected components, each with a specific function. One of the major strengths of this system is modularity. Following are brief overview of a typical system. Solar array: it consists of one or more PV modules, which converts sunlight into electric energy. The modules are connected in series and/or parallel to provide the voltage and current levels to meet customer"s needs. The array are usually mounted on a metal structure and tilted to face the sun (tilt angle = latitude +15°). Charge controller: the main function is to maintain the batteries at the proper charge level, and protects them from overcharging. Battery bank: this contains one or more deep-cycle batteries, connected in series and/or parallel depending on the voltage and current capacity needed. The batteries store the power produced by the solar array and discharges it when required. Inverter: an inverter is required when users want to power AD devices. The inverter converts the DC power from the solar array/batteries into AC power. AC and DC loads: these are the appliances (such as, lights or radios), and the components (such as, water pumps and microwave repeaters), which consume the power generated by solar array (module). Balance of system: these components provide the interconnections and standard safety features required for any electrical power system. These include: array combiner box, properly sized cabling, fuses, switches, circuit breakers and meters (customer requirement).
