A Solar panel is designed to absorb the sun’s radiation as a source of energy for generating electricity or heat.
A typical solar panel is a photovoltaic (PV) module which is a packaged, connected assembly of typically 6×10 solar cells in a row column layout. These panels constitute the solar array of a photovoltaic system which generates and supplies electricity from the solar radiation to commercial and residential requirements. Each PV module is rated by its output power which is measured in DC under standard conditions, they typically ranges from 100 to 365 watts. The efficiency of a module is important for determining the area of a module. For instance – an 8% efficient 200 watt module will have twice the area of a 16% efficient 200 watt module.
How to install solar panel:
Now that the technology of a solar panel is clear, we can proceed to the installation part.
There are two crucial factors that should be evaluated before installing a solar panel.
1. Is it feasible for me to get a solar panel?
2. What size panel should I use for optimum utility?
These factors should be evaluated by an engineer for best results, also positioning of the solar panel is very important, as it should receive maximum sunshine and minimum obstructions.
Once these evaluations have been done a solar panel is ready to install, following are the points for how to install solar panels:
1. Bury a conduit from the house that will receive the power to the area where the solar panel array will be located.
2. Build a platform over this conduit that will support the solar panels.
3. After building the platform mount the panels on the platform and fix them at the proper angle.
4. Wire the solar modules together and join them at a junction connector or fuse combiner box. The modules should be stripped and wired in pairs before being connected to the fuse box mounted at the platform and connected to underground conduit output cables.
5. Now connect this external wire to the internal control panel. The energy will first flow into a circuit breakerthen the energy will flow from the circuit breaker to a charge controller and then to a battery bank to be stored. When needed, energy flows from the batteries back to the circuit breaker disconnect and from the disconnect to a power inverter to convert the DC current to AC. This AC current can then be used for our household needs.
6. The whole system needs to be grounded, put a grounding rod into the earth near the solar panels, run copper grounding wire from the rod to the fuse box and from the solar panels to the fuse box.
7. After the grounding is done, make the proper electrical connections inside. The wires from the inverter should be connected to all the appliances that you wish to power from the solar panels. This can be a little complicated and its best to call a professional and get the wirings done.
Once all these steps have been carried out run a few tests to be sure and you should have a fully operational solar panel ready to power an array of appliances.
