Solar Panels 

Solar panels, also known as solar modules, convert sunlight into electricity. Solar panels that are used commercially are made of silicon cells and are called monocrystalline. Monocrystalline silicon cells have fewer imperfections, and therefore generate at the highest efficiency rate. Solar modules made with polycrystalline cells, which contain...

    These are the solar panels you see on your neighbors rooftop. They are known as grid-tie solar panels or high-voltage solar panels. When used in a grid interconnected system, panels are connected in series to achieve voltages of 600VDC and 1000VDC. The high DC voltage is then converted to AC voltage compatible with the utility grid. It is also possible to use micro inverters, where you have an inverter for every solar panel instead of a central inverter. Solar panels for interconnection are available with different characteristics. They can be either monocrystalline or polycrystalline . Some models offer the anodized aluminum frame in black color, while other models also offer an all-black module (with black frame and black background), thus improving the final appearance of the solar array. All grid-tie solar panels come with connection cables. These cables are fixed, they cannot be cut nor removed. The connection cables are double insulated and are made of materials resistant to UV rays. They allow for an easy connection of the modules and ensure that all connections are safe and rated for outdoor use. The end connectors on the cables can be composed of different types and might not always be compatible with each other. The most common connectors are Multi -Contact (MC), Tyco and Amphenol.

    The great majority of direct current (DC) battery systems operate at 12, 24 and 48 volts. It is recommended to use 12 and 24 Volt solar panels in these systems as they provide the proper voltage to charge the batteries eliminating the need to step down the voltage. The solar panels can be paired in series to match the system voltage; for example, 4 12V panels or 2 24V panels can be connected in series to supply power to a 48V system. The solar panels in this section can be as small as 5W and are available in increments up to 140W. Only larger panels include cables, smaller panels have a junction box in the back for connections. Some of the more common applications include street lighting, recreational solar systems, beacons and marine buoys, telecommunications systems, water pumping, signage, RVs, boats and remote cabins. With the exception of the 5W solar panels is always recommended to use a charge controller between the batteries and solar panels. The charge controller will protect the batteries from over-charging.
