Q2: How long do photovoltaic (PV) systems last?
A PV system that is designed, installed, and maintained well will operate for more than 20 years. The basic PV module (interconnected, enclosed panel of PV cells) has no moving parts and can last more than 30 years. The best way to ensure and extend the life and effectiveness of your PV system is by having it installed and maintained properly. Experience has shown that most problems occur because of poor or sloppy system installation.
Q10: How it uses in UK?
In the UK, PV installations are generally considered permitted
development and don't require planning permission. If the property is
listed or in a designated area then planning permission is required.
Q1: What are the components of a photovoltaic (PV) system?
A PV system is made up of different components. These include PV modules (groups of PV cells), which are commonly called PV panels; one or more batteries; a charge regulator or controller for a stand-alone system; an inverter for a utility-grid-connected system and when alternating current (ac) rather than direct current (dc) is required; wiring; and mounting hardware or a framework.
Q4: Can I use photovoltaic (PV) to power my home?
PV can be used to power your entire home's electrical systems, including lights, cooling systems, and appliances. PV systems today can be blended easily into both traditional and nontraditional homes. The most common practice is to mount modules onto a south-facing roof or wall. For an additional aesthetic appeal, some modules resemble traditional roof shingles
Q5: Where can I find someone who designs, installs, and maintains photovoltaic (PV) systems?
We suggest you look for a PV installer or equipment provider in the telephone directory under "Solar Energy Equipment and Systems Dealers."
Q6: What is the photovoltaic system?
A photovoltaic system (informally, PV system) is an arrangement of components designed to supply usable electric power for a variety of purposes, using the Sun (or, less commonly, other light sources) as the power source.
Q8: What’s the most advantage the photovoltaic systems have?
Solar power is pollution-free during use.
Q9: What’s the most disadvantage of the photovoltaic systems?
The prize to make a photovoltaic is too high.
Q3: What's the difference between PV and other solar energy technologies?
There are four main types of solar energy technologies:
Photovoltaic (PV) systems, which convert sunlight directly to electricity by means of PV cells made of semiconductor materials.
Concentrating solar power (CSP) systems, which concentrate the sun's energy using reflective devices such as troughs or mirror panels to produce heat that is then used to generate electricity.
Solar water heating systems, which contain a solar collector that faces the sun and either heats water directly or heats a "working fluid" that, in turn, is used to heat water.
Transpired solar collectors, or "solar walls," which use solar energy to preheat ventilation air for a building.
Who It Works
Photovoltaic (PV) is a method of generating electrical power by converting solar radiation into direct current electricity using semiconductors that exhibit the photovoltaic effect.
The sun light in the semiconductor p-n junction, the formation of new hole electron pairs, in the p-n node under the action of electric field, the hole flow from the n area of P District, electrons flow from the P area of N District, connected to the circuit after the current form. This principle is the photoelectric effect of solar cell.
The two way of the photovoltaic
1.the control is difficult to ordinary people
1.the energy is rich and can reproducible
2.solar electric generation has the highest power density (global mean of 170 W/m2) among renewable energies.
3.the cost is less
4.Grid-connected solar electricity can be used locally thus reducing transmission/distribution losses .rapidly falling.
Q7: How to collect the solar energy uses the photovoltaic systems?
During the day, under the condition of light, solar battery
components produce certain electromotive force, through component of
series-parallel solar cell phalanx formation, makes the square voltage
to achieve the requirement of the system input voltage. Again for
battery charging, the charging and discharging controller will be used
by light conversion of electrical energy storage.
