The use of solar photo voltaic modules in our lives
Photo Voltaic Solar modules are best known as a method for generating electricity using solar cells to convert energy sunlight into electricity. The photovoltaic effect refers to the photons of light hitting electrons to a higher state of energy to create electricity.
In buildings:
building-integrated photovoltaic (BIPV) are increasingly incorporated into new residential and industrial buildings, such as primary or secondary source of electrical energy, and are one of the fastest growing segments of the PV industry. Normally, an array is incorporated into the roof or walls of a building with photovoltaic panels and tiles you can buy now integrated. Arrays can also be installed in existing buildings, in this case are usually installed on top of existing roof structure. Alternatively, a matrix can be separated from the building but connected by cable to supply power for the building.
When a building is in a considerable distance from the public grid (or network) – in remote or mountainous areas – PV may be the preferred option for generating electricity, or PV can be used together with wind, diesel generators and / or hydroelectric power. In such circumstances beyond the network batteries are usually used to store electricity.
In places close to the network, however, food network using photovoltaic panels is more practical, and leads to use optimal investment in the photovoltaic system. This requires regulatory and commercial preparation, measurement and power network in the agreements. systems for possible power outage, some linked network are configured to allow local use disconnects from the network. Most grid-connected photovoltaic. In the case of network fails, the local system should not feed the network to avoid the possible creation of dangerous islands.
The power output of PV systems for installation in buildings are usually described in units of kilowatt peak (kWp).
In transportation:
PV has traditionally been used for food auxiliary space. PV is rarely used to provide motive power in transport applications, but is being used increasingly to provide auxiliary power in boats and cars. Recent advances in solar race cars, however, have produced cars that change and can be used for transport.
Independent Device:
Until a decade ago, PV is often used to power calculators and novelty devices. The improvements in integrated circuits and LCD displays enable low-power to power these devices for several years between battery changes, making PV use less common. On the contrary, it works solar powered remote fixed devices have seen their recent places where the cost of significant electrical networking makes it prohibitively expensive. These applications include parking meters, emergency telephones, traffic temporary signs, and remote guard posts and signs.
Electrification Rural
Developing countries where many people are often more than five kilometers from the power supply have begun using photovoltaics. In areas India's remotest rural lighting program has been providing power LED solar lighting to replace kerosene lamps. Energy lamps solar sold almost the cost of a few months supply of kerosene. Cuba is working to provide solar energy to areas outside the network. These are areas where the social costs and benefits offer an excellent case to go solar but the lack of profitability could relegate such efforts to the humanitarian objectives.
