Solar PV

Small Solar Home System

Solar Home Systems (SHS) are used where there is no electricity grid. You need a battery to ensure the availability of light at night or when it is dark. Lights, fans, and some times TV are the three basic needs of remote areas which can make good use of the SHS kit. For wider needs the kit obviously becomes more varied. A solar panel, a control unit, battery storage, cable and support structure comprises the kit.

The Stand Alone Power has everything built into one. No electric connection is required. This solar electricity device can be installed very easily. A battery backup only an uninterrupted power. The inverter of this system works as the intelligence center of a renewable energy system, converting DC power to reliable AC electricity for your needs.

Solar water pumps are of great utility, working on solar PV system. Water pump sets of 1 -2HP can be run using this system. Lifting water from well from natural water beds after boring is possible. The only limitation is that the system has to be installed in a shadow free area. The most attractive aspect of this system is that it not only eliminates electricity usage but also fossil fuels and therefore is eco-friendly. Operation and maintenance is easy.

Some renowned mobile phone companies are making a beeline for filing patents in integrated solar cells to power their iPods and Androids with PV cells to various parts of their computers, display devices, input devices, and materials from which their logo is etched.

GreenTech has already introduced Small Form Factor (SFF) computers. Most SPC machines are based on the Common Building Block (CBB) and feature interchangeable components. CBB promotes standardization to enable organizations to maximize up time and minimize the total cost of PC ownership.


Solar Lanterns

solar lanternConfigurations will change with the consumers’ demands. This lantern is especially popular in the rural areas where sunlight is abundant but conventional energy supply irregular or uncertain. Commonly, an LED lamps are provided as per the need but the light emitted will be white, of high power LEDs totaling 1.8 watt. One may opt for stronger units with higher illuminating power, of course for a slightly higher price. You may opt for a lead acid accumulator battery backup to get a 7 watt CFL lamp working for you. Higher configurations are also available, but these are all recommended for indoor use.

Garden Lights

Solar Garden Lights

Urban people fancy gardens if they own homes with some space. A substantial amount goes into gardening. But night time illumination one has to incur recurring additional expenditure to give the evening prime time viewing pleasure. Here the solar garden lights come into consideration. A dream view of the garden unfolds before the otherwise dark surrounding with solar luminaries, almost for a song! A three hour light up from six to nine is enough provision for the owner and his associates to unwind in garden chairs.


Solar Street Lights

These lights are meant for mainly for outdoor illumination. Street lighting, pavement lighting, pathway illumination come into consideration. Since these units are exposed to varying weather conditions all the year round, they come with a rugged design. 60-80 LED lamps connected to sensors help them get switched on or off according to the ambience.

Backup time unto 16 hours on a single charge of the lead acid battery is lodged lower down on the pole of the street light.The charge is derived from the solar PV panel lodged higher up to trap maximum sunlight.


Roof Top Power Plants

The roof top power plants use photo-voltaic cells which are solid state semi-conductor devices which help transforming solar energy to electric DC. The cells are connected in parallel to obtain the desired output – named as Solar Modules but when connected in series to meet the load requirement, they are termed as Solar Array. A lead acid battery is charged by the Solar Module. The charged control unit controls over charging and deep discharging of the battery, thus enhancing the battery life. The inverter used in this device converts the DC to 230 volts AC of 50Hz frequency.

This system produces power as long as sunlight is available, i.e. during the day time. At night time, the battery backup linked to the system does the job. The capacity of the battery will directly be related to the amount of power required.

A roof top power plant can produce 1KW to 100KW peak AC power. It is kept inclined, mounted on a raised secured structure with a 10 ft clearance from its lower surface to the ground. It can be upgraded to generate 100KW and above.

Solar water pumps which are of great utility also work on solar PV system. Water pumps sets of 1-2 HP can be run using this system. Lifting water from wells or from natural water-beds after boring can done. The only limitation is that the system has to be installed in a shadow free area. The most attractive aspect of this system is that it not only eliminates electricity usage but also fossil fuels and therefore is eco-friendly. Operation and maintenance is easy.
