1. On-grid.
2. Off-grid
On grid
Grid-tied systems can be upgraded to include a battery backup: a bank of deep-cycle batteries. The backup battery is charged by both the grid and the solar panels. In the event of an outage, the backup battery will need to be switched on either manually or with an automatic system to provide backup power to the building.
• PV panels
• battery bank
• charge controller (to protect the battery bank from overcharge)
• inverter
• required electrical safety gear (i.e. fuses, breakers, disconnects)
• monitoring system to monitor energy production (optional)
Off grid
It is possible to install a solar system that is independent of the electrical grid. This is called an off-grid system, and it requires that the solar panels are able to produce enough electricity to cover 100% of the energy needs of the buildling. Most homes have higher electricity demand in the evening or at night, so off-grid systems usually incorporate either a battery (to store energy produced during the day), a backup source of energy (like a generator), or both. Off-grid systems are more complex and less flexible than grid-tied systems. Off-grid systems are most common in remote locations without utility service. Off-grid solar-electric systems operate independently from the local utility grid to provide electricity to a home, building, boat, or RV (or remote agricultural pumps, gates, traffic signs, etc.). These systems typically require either a battery bank (to store solar electricity for use during nighttime or cloudy weather) a backup source of energy (like a generator), or both. An off-grid solar system must be large enough to produce enough electricity to cover 100% of the energy needs of the buildling. In all off-grid scenarios, electrical usage must be monitored and kept below the maximum output of the panels and batteries as there is no grid-source to supply excess power. System components:
• PV panels
• battery bank
• charge controller (to protect the battery bank from overcharge)
• inverter
• required electrical safety gear (i.e. fuses, breakers, disconnects)
• monitoring system to balance energy consumption with production
grid tie
Grid-tied systems are the most common type of solar PV system. Grid-tied systems are connected to the electrical grid, and allow residents of a building to use solar energy as well as electricity from the grid. Grid-tied systems do not need to produce 100% of the electricty demand for a home or business. When there is no demand for energy, the solar panels send excess electricity back out into the grid for use elsewhere. When a home or business is using energy, but the solar panels aren't producing enough energy (at night, or on a stormy day), electricity from the grid supplements or replaces electricity from the panels. Owners of a grid-tied system complete a net metering agreement with their utility. This agreement allows utility customers to receive credit for the excess energy they generate, typically credited as a kilowatt-hour credit on the next month's bill. Net metering policies and agreements are different for each utility. Living with a grid-tied solar PV system is no different than living with utility electricity, except that some or all of the electricity you use comes from the sun. Grid-tied systems do not provide protection from power outages. When the electrical grid fails, grid-tied systems will not continue to operate. This allows utility employees to fix the power lines safely without wasting time identifying solar energy systems that are still feeding electricity into the power lines. System components:
• PV panels (multiple panels make up an array)
• inverter(s)
• required electrical safety gear (i.e. fuses, breakers, disconnects)
• monitoring system to monitor energy production (optional)
pv direct
These are the simplest of solar-electric systems, with the fewest components. PV-Direct systems don't have batteries and are not connected to utility, so they only provide electricity when the sun is shining. This means that they are only appropriate for a few select applications, notably water pumping and ventilation. A PV-Direct system can be a simple and efficient way to run a fan or a water pump whenver the sun is shining. System components:
• PV panels
• required electrical safety gear (i.e. fuses, breakers, disconnects)
solar themal
Solar thermal systems can be designed with energy storage in mind as well. There is no way to feed hot water back to the water utility, so hot water must be stored on site. This is generally accomplished using a home's hot water tank, just as conventionally heated water would be stored. While there are many iterations of solar thermal design, most take advantage of the existing hot water tank. In some systems, the water tank can double as a back-up or supplementary heater. Solar Application
Solar power applications
by Barbara M. Drazga
Concentrating Solar Power (CSP): Concentrating solar power (CSP) plants are utility-scale generators that produce electricity using mirrors or lenses to efficiently concentrate the sun’s energy. The four principal CSP technologies are parabolic troughs, dish-Stirling engine systems, central receivers, and concentrating photovoltaic systems (CPV). Solar Thermal Electric Power Plants: Solar thermal energy involves harnessing solar power for practical applications from solar heating to electrical power generation. Solar thermal collectors, such as solar hot water panels, are commonly used to generate solar hot water for domestic and light industrial applications. This energy system is also used in architecture and building design to control heating and ventilation in both active solar and passive solar designs. Photovoltaics: Photovoltaic or PV technology employs solar cells or solar photovoltaic arrays to convert energy from the sun into electricity. Solar cells produce direct current electricity from the sun’s rays, which can be used to power equipment or to recharge batteries. Many pocket calculators incorporate a single solar cell, but for larger applications, cells are generally grouped together to form PV modules that are in turn arranged in solar arrays. Solar arrays can be used to power orbiting satellites and other spacecraft, and in remote areas as a source of power for roadside emergency telephones, remote sensing, and cathodic protection of pipelines. Solar Heating Systems: Solar hot water systems use sunlight to heat water. The systems are composed of solar thermal collectors and a storage tank, and they may be active, passive or batch systems. Passive Solar Energy: It concerns building design to maintain its environment at a comfortable temperature through the sun’s daily and annual cycles. It can be done by (1) Direct gain or the positioning of windows, skylights, and shutters to control the amount of direct solar radiation reaching the interior and warming the air and surfaces within a building; (2) Indirect gain in which solar radiation is captured by a part of the building envelope and then transmitted indirectly to the building through conduction and convection; and (3) Isolated gain which involves passively capturing solar heat and then moving it passively into or out of the building via a liquid or air directly o
