What are the basic components of rooftop Solar power plant?

The technology that makes residential solar power possible is fairly simple. It basically consists of photovoltaics and the equipment needed for a grid-tied solar electric system.

The Photovoltaics effect

Photovoltaics is the technology that makes this wonderful source of energy possible. While the technology has been around for more than a century, it has only been in recent decades that it has become both efficient enough and cost effective. New breakthroughs always seem to be right around the corner. However, the fact is that solar power is ready for mass adoption right now.

Solar Panels

Most of us first think of Solar Panels  when solar power comes to mind. After all, this is what we see on the rooftops of Solar power plant owners that have adopted this energy source. Although there are quite a few different types and manufacturers, they are quite similar in basic function. Future technology promises less space needed on roofs as overall solar cell efficiency improves.


Solar Inverters

A solar inverter, or converter or PV inverter, converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network. It is a critical balance of system (BOS)–component in a photovoltaic system, allowing the use of ordinary AC-powered equipment. Solar power inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.

Net Metering

Net Metering is easily one of the most important pieces of the residential solar puzzle. Solar PV system owners can benefit from the energy their systems produces in excess of what is used. As of late 2013, most Indian  states have adopted Net metering policies. This technology is key in the further development and expansion of the distributed energy source that is residential solar power.

Putting it all together, a residential Solar Energy system  includes everything that is needed for a homeowner to take advantage of this abundant energy source. Another great thing about solar power is that the set up is actually quite straightforward for a properly trained solar installer. This is definitely helping speed the adoption rate of solar throughout the country.

As seen in the diagram above, solar panel systems will also increasingly include micro-inverters and energy storage in the form of lithium-ion batteries. Both of these technologies help homeowners make better use of the electricity that solar panels produce.
