2. MC4 connector - Wikipedia

   en.wikipedia.org/wiki/MC4_connector

   While small solar panels used for battery charging and similar tasks may not require special connectors, larger systems normally connect the panels together in series to form strings. In the past, this was accomplished by opening a small electrical box on the back of the panel and connecting user-supplied wires to screw terminals within.

3. Balance of system - Wikipedia

   en.wikipedia.org/wiki/Balance_of_system

   The solar cell technology is still evolving and improving, and costs are being reduced fast. The balance of systems consists mostly of items which are not specific to solar technology. As an example, the mounting structures are quite usual and the technology may already be mature, benefitting little from further innovation and research.

4. Solar charger - Wikipedia

   en.wikipedia.org/wiki/Solar_charger

   A solar charger is a charger that employs solar energy to supply electricity to devices or batteries. They are generally portable. Solar chargers can charge lead acid or Ni-Cd battery banks up to 48 V and hundreds of ampere hours (up to 4000 Ah) capacity. Such type of solar charger setups generally use an intelligent charge controller.

5. Charge controller - Wikipedia

   en.wikipedia.org/wiki/Charge_controller

   In solar applications, charge controllers may also be called solar regulators or solar charge controllers. Some charge controllers / solar regulators have additional features, such as a low voltage disconnect (LVD), a separate circuit which powers down the load when the batteries become overly discharged (some battery chemistries are such that ...

6. Stand-alone power system - Wikipedia

   en.wikipedia.org/wiki/Stand-alone_power_system

   In stand-alone photovoltaic power systems, the electrical energy produced by the photovoltaic panels cannot always be used directly. As the demand from the load does not always equal the solar panel capacity, battery banks are generally used. The primary functions of a storage battery in a stand-alone PV system are:

7. Photovoltaic system - Wikipedia

   en.wikipedia.org/wiki/Photovoltaic_system

   A photovoltaic system, also called a PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics.It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to convert the output from direct to alternating current, as well as mounting, cabling, and ...
