Solar Photovoltaic Power Generation System Engineering ppt

What are the different types of solar PV technologies?

The document outlines different types of solar PV technologies like monocrystalline, polycrystalline and thin film solar cells. It also discusses designing of solar PV systems including components like blocking diodes and bypass diodes. The advantages and disadvantages of solar energy systems are highlighted.

What are the different types of solar power generation technologies?

There are two main technologies for solar power generation: solar photovoltaics and solar chimney technologies. Solar photovoltaics convert sunlight directly into electricity via photovoltaic cells. They can be ground mounted or space based. Floating solar chimney technology uses the greenhouse effect to power turbines.

What is a photovoltaic cell?

It describes the construction and working principle of photovoltaic cells made of semiconductors like silicon. The document outlines different types of solar PV technologies like monocrystalline, polycrystalline and thin film solar cells.

What are the advantages of solar photovoltaic (PV)?

Advantages of Solar photovoltaic (PV) Benefit from the Governments feed‑in tariff. The feed-in tariff is guaranteed by the Government for 20 years. Panels designed for European countries generate power even on cloudy days. Clean energy means carbon emissions can be reduced. Producing your own power protects against rising energy prices.

What are the disadvantages of solar photovoltaic (PV)?

Disadvantages of Solar photovoltaic (PV) A large area of unshaded south, south-west or south-east facing roof is required to maximise payback. Smaller systems can be installed but payback will be longer. Panels degrade over time by approximately 20% over 25 years; this however is taken into account in most reputable suppliers calculations.

How many volts does a PV module produce?

Cell: The basic photovoltaic device that is the building block for PV modules. All modules contain cells. Some cells are round or square, while thin film PV modules may have long narrow cells. Cells are too small to do much work. They only produce about 1/2 volt, and we usually need to charge 12 volt batteries or run motors.
