The Solar PV Panel consists of a 9V/1.5W solar module with a 5M cable that provides flexibility in being able to suitably locate the Solar Panel to maximise the solar input during the daylight hours, and still have enough length in the cable to extend the light to a point where it can be best utilized. The Solar PV module has a life cycle of approximately 10 years and is warranted for 5 years. The inbuilt controller provides protection against over-charging and over-discharging and also includes short-circuit protection. The battery pack consists of 5pieces of AA size x 1000mAH NI-MH (Nickel Metal Hydride) rechargeable batteries that are housed in a strong UV stabilized, heat resistant ABS plastic material for durability and longer life. The LED Lamp that is supplied with the kit is a 1piece x 9V with 18 Light Emitting Diodes (LED) together with a 4M cable. A Mobile phone Charger connection in the battery pack allows direct mobile phone charging and several different types of plugs are supplied with the kit to cover most popular types of mobile phones.
In addition the Model SRY-002-1 has a separate compartment provided in the front of the ABS battery pack where two (2) 600mAH NI-MH rechargeable batteries, that are supplied with the kit can be charged during the daylight period as well. These batteries can be used in a flashlight or a portable radio. After the solar PV module has been charged for between 6-8 hours there are three brightness setting options that can be used for the LED light. The three settings will offer the following performance: maximum brightness around 6 hours, energy saving mode around 12 hours, and low brightness mode approximately 50 hours of operation. The Model SRY-002-1 instruction manual is available in English and French and dependent upon quantities other languages are available as well. Each Kit weighs approximately one kilogram and is packed in a strong packaging box measuring 245mm x 195mm x 510mm. Standard Packs comprise of 10 pieces per carton which measures 410mm x 280mm x 255mm and has a gross weight of around11 Kg.

|Multi-Function Heat Pump|
The use of energy efficient Japanese brand Mitsubishi, Panasonic, and Sanyo rotary or scroll compressors, depending upon the product capacity needed, as well as two (2) separate high efficiency plate heat exchangers, this combination significantly improves the energy efficiency to the point where the combined Coefficient of Performance (COP) for the heating and the cooling functions can be as high as seven (7) which represents an energy saving of 700% when compared to the electrical energy that would be consumed by separate electrical hot water system and air conditioners delivering the same volume of cool air and the same volume of hot water each day. Whilst the electricity tariff supplied by the local utilities in any Region will still be the same the “effective” tariff would be 7 times less to deliver the same performance due to the efficiency of the combined Multi-Function Heat Pump Units. For example if the actual tariff was the equivalent of US $0.12 cents per kWh then the “effective” tariff would be approximately US $0.02 cents per kWh.
