Solar Panels

Solar Panels, also known as Solar Photovoltaic (PV), capture the sun’s energy using photovoltaic cells. These cells don’t need direct sunlight to work – they can still generate some electricity on a cloudy day. The cells convert the sunlight into electricity, which can be used to run household appliances and lighting.

PV cells are made from layers of semi-conducting material, usually silicon. When light shines on the cell it creates an electric field across the layers. The stronger the sunshine, the more electricity is produced. Groups of cells are mounted together in panels or modules that can either be mounted on your roof or on the ground. The power of a PV cell is measured in Watts peak {Wp}. That’s the rate at which it generates energy at peak performance in full direct sunlight during the summer. PV cells come in a variety of shapes and sizes.

Mono Crystalline Solar Panels

Mono Crystalline Solar Panels have the highest efficiency rates since they are made out of the highest-grade silicon. The efficiency rates of mono crystalline solar panels are typically 15-20%. They can perform better than similarly rated polycrystalline solar panels at low-light conditions. Mono Crystalline Silicon Solar Panels are space-efficient. Since these solar panels yield the highest power outputs, they also require the least amount of space compared to any other types. Mono Crystalline solar panels produce up to four times the amount of electricity as thin-film solar panels. Mono Crystalline Solar Panels live the longest. Most solar panel manufacturers put a 25-year warranty on their Mono Crystalline solar panels.

Poly Crystalline Solar Panels

In the Poly Crystalline Solar panels the cells are cut from an ingot of melted and recrystallised silicon. In the manufacturing process, molten silicon is cast into ingots of polycrystalline silicon, then saw-cut into very thin wafers and assembled into complete cells. Polycrystalline cells (also known as multicrystalline) are cheaper to produce than monocrystalline ones, due to the simpler manufacturing process. However, they tend to be slightly less efficient for the same size cell. Polycrystalline Panels typically offer a lower cost per watt of power produced. These cells have a better temperature de-rating co-efficient compared to monocrystalline, meaning they produce more power in hotter weather, which usually more than offsets their slightly lower cell efficiency. Polycrystalline cells are slightly less efficient than monocrystalline cells, so they need more roof space to produce the same output capacity.
