Photovoltaic (PV) systems
PV system's make electricity from sunlight. This electricity can be use to power
electrical items in your house or sold back to the grid if there is an excess.
Why is PV so popular:
- Suitable for almost every roof
- Great investment especially with government incentives
- Long warranties on panels (typically 25 years on performance)
- Minimal maintenance
- No problems storing the electricity as sold back to grid
- Very reliable as almost no moving parts
There are 4 main components in most solar photovoltaic (PV) systems.
- The first is the solar power array which is a collection the solar power producing cells. This converts the suns energy into DC electricity.
- The second is the roof mounting structure consisting of aluminium or stainless steel components that are used to mount the solar power collector system onto the roof of the building. There are two major types; (1) roof integrated where the solar power panels replace the tile and become flush with the rest of the roof (2) on-top mounting where the solar power panels sit above existing roof tiles.
- A special solar power inverter is then required to convert the DC (direct current) electricity into AC (alternating current) electricity, which can be used by most home appliances or sold back to the grid.
- The final part is when the solar power collector system is linked to your fuse box and an electric meter so you can tell how much energy you have produced and how much unused energy you have sold back to the grid.
Solar Power Cells, Modules and Arrays
The basic PV building block is the photovoltaic panel. A PV panel converts energy
from the sun directly into solar power. There are a range of solar panels available
- Monocrystalline, Polycrystalline and Hybrid panels and with often options of silver
or black back sheets and frames.
Storage of Energy
Photovoltaic PV systems can be designed to sell any surplus energy back to electricity grid rather than store the energy. We also sell a range of storage solutions if customers want to maximise their usage of their self generated energy and possibility giving them some emergency power in case of a power cut.
