A photovoltaic cell (cell) solar panels (solar cells panel) SUN Solar Cells, or photovoltaic cells, denoted as PV, is a system of plate special materials capable of converting solar energy of sunlight into electricity. SUN Solar cells are made up of photovoltaic cells (cells) single crystal (monocrystalline) and poly-crystalline (polycrystalline) high performance (15% - 18%), with a capacity of up to 175Wp and older 25Wp 30 year average life.

II - Principle of operation of the Solar System:

From solar truss, light is converted into electricity, generating direct current (DC). This electric current is led to the control electronics is a function automatically regulate the process of charging and discharging the battery power from the battery to the device (DC). Where big enough battery capacity rigs, the circuit will be fitted with adapter to convert direct current into alternating current (AC), run more electrical appliances (lights, fan, radio, TV ... ).

III - TYPICAL CONFIGURATION OF SYSTEM PIN SOLAR:

1 - SOLAR PANEL "SUN":

SUN solar panels (solar cells panel) optical variable absorption from the sun to turn into electricity.

Some basic information about solar panels SUN:

Performance: from 15% - 18%

Capacity: from 25Wp to 175 Wp

The number of cells per panels SUN: 72 cells

Cells Size: 5-6 inchs type cells: monocrystalline and polycrystalline

Material of frame: aluminum

The average life expectancy of the panels SUN: 30 years

Being able to connect the solar power stations of large capacity is not limited, the grid can (grid), or as one independent back-up power systems.

In a sunny day, the sun provides about 1 kW / m² to the ground (when the sun shine and clouds standing at sea level).

Capacity and voltage of the system will depend on how we reassembling the SUN solar panels together.

The SUN solar panels are installed outdoors to be able to catch the best sunlight from the sun should be designed with features and special material that can withstand the rigors of the weather, climate, temperature ...

2. Charger controller:

- A device that performs regulatory functions for battery charging and protection for battery against overload and discharge process, to increase the average life expectancy of the batteries, and help systems use solar cells and long-term effectiveness. - The controller said charging status of the solar panel to the battery enables users to control the load. - The controller is implemented overcharge protection voltage (> 13.8 V) or low voltage (<10.5 V). Protection circuitry of the controller performs the circuit breaker when the control validation average battery was fully charged or voltage too low average.

3. The AC-DC INVERTER:

- A power inverter converters. Inverter to convert 12V DC current from the battery into alternating current (110VAC, 220VAC). Designed with power levels from 0.3kVA - 10kVA.

- Inverter with multiple types and distinguish them by way of the voltage waveform outputs: sine waveform, assuming sine, square wave, wave ladder ...

4. BATTERY (battery-operated)

- A power storage devices for use at night or when the sky is little or no sunlight.

- The battery has many types, sizes and capacities vary, depending on capacity and features of the SUN solar system. The system will need larger capacity batteries used with large or multiple user-specified battery connected together.

5. BRACKET AND CABLE GA:

- To ensure the SUN solar system put in place the best (and most sunny longest) and the utilization of the system is always stable and long-term, we need to use the pad frames and cables dedicated.

- To maximize the performance of the system, the solar panels should be installed in one angle and one certain direction (depending on each specific installation location).

- Note when installing avoid areas likely to be covered, hidden sun, so choose the location can best inspiration was sunny all day.

- The synchronized with accessories: pipes, switches, electrical panels, Vaseline, domino, socket ... to complete the installation of solar power systems

IV. Several key characteristics of the solar cell system SUN:

- SUN solar system in particular, or PV systems in general, can not produce electricity continuously, it works only when the sun shines on the panels.

- Reliability of vaddo durable SUN solar system is very high, a typical system can operate up to 35 years ddong virtually no maintenance.

- With a solar system just ddau SUN-from a single time. Like the previous Payment for electricity for many years (20-25nam), your monthly electricity bill will be reduced significantly.

- The average investment cost of a solar power system for about $ 20,000 a house. The operating life of the system average of 30 years, homeowners will save about $ 40,000 electric bill.

- The performance of the system is probably the most important factor to compare costs with benefits that the system offers.

- SUN solar cells have the advantage of being economically efficient, compact, lightweight, can be mounted anywhere with sunlight, it is absolutely safe to use and is completely environmentally friendly.

- The SUN solar system capable electric grid or operate independently, and can provide power for many applications: from the power supply system for buildings, apartments, to the system electricity for public lighting system, or to the telecommunications relay stations remote ... V.

V. The solar system typical of Sunderland:

Demand for electrical equipment with 100Wp solar system (2 panels 50 WP)

Demand for electrical equipment with 200Wp solar power system (4 sheets 50 WP)

Demand for electrical equipment for power 500Wp system (10 panels 50 WP)

In addition to the typical system, the SUN has provided consultancy, design and installation of solar systems by using the actual needs of the customer, to ensure the most effective and economic usefulness.
