Solar PV Module
Solar PV Panels (PV Modules) are semiconductor devices which convert light into electrical energy. Panel is the most important component of a Solar Photovoltaic System. Around 50% of the total SPV system cost is that of solar panel.
Available brands: ISOFOTON, TATA BP, MITSUBISHI, KOMAES
Avaiable capacity: 10 Wp to 175 Wp (12 V & 24 V nominal)

Inverter
Inverters are electronic devices that convert DC (Direct Current) energy stored in the batteries to AC (Alternating Current). The nominal input voltage of an inverter can be 12 to 240 VDC (in multiple of 12) and the output AC voltage matches that of the household supply voltage from the grid. Inverters can have differences in features (including the wave form) depending on the kind of use.
Available Brands: CENTRALION, ASIAN ELECTRON (Taiwanese)
Available Range: 600 W to 3.2 kW

Solar Street Lamps
Solar street lamp is one of the most successful solar PV applications in the world. These lamps (CFL or WLED based) operate automatically from dusk to dawn and the complete system can be designed in accordance to the specific illumination requirements. These lamps can be deployed in village centers, pathways leading to resorts, offices and other sensitive areas. Due to frequent load shedding problems these can in fact be suitable for urban / semi-urban areas too.
Portable Power Pack
Portable or semi-portable systems to run laptops, slide projectors, TV/ VCRs, communication equipment can also be custom manufactured as per specific requirements.

Deep Cycle Battery
Battery is a device which stores electrical energy in the form of chemical energy. In case of solar PV system, energy generated by the solar PV module is stored in the battery. Although battery can be of different types, for solar PV system Lead Acid battery with tubular positive plates are considered to best in terms of economic viability.
Available Brand: VOLTA
Available Capacity: 20 Ah to 140 Ah @ C20 (12 V Block batteries)
400 & 660 Ah @ C10 (Industrial 2 V cells with design life of over 10 years.)

Standalone PV system
These are custom designed systems appropriate for running electrical and electronic appliances in remote areas where there is no other means of electricity. Depending on requirement, the size of standalone solar PV system can vary from 100 Watt peak to several Kilowatt peak. Suryodaya Urja designs, manufactures and implements stand-alone systems to run office complexes, hotels and lodges in turnkey basis in accordance to customer’s requirements.

Charge Controller
Charge controllers are electronic gadgets used for protecting lead acid batteries from being over charged or over discharged. The main function of the Charge Controller is to disconnect the solar PV array from the battery when the battery is fully charged to a preset level and disconnect the load when the battery is discharged to a permissible level.
Available Brands: Isofoton, Sundaya, Phocus and Suryodaya
Available Range: 5 Amps to 30Amps for 12/ 24 V application

Solar PV Pumping System
These systems use high efficiency pumps in conjunction with PV arrays to offer pumping solutions to areas without electricity. According to the total vertical lift (head) and volume requirement, the pumps and PV array can be configured in various sizes. These systems have complete synergy with nature - we generally need more water on hot days with plenty of sunshine when the pumps proportionately lift more water. Also, pumping systems do not require batteries as the storage can be purposefully done by having larger tanks.
Available Brand: Grundfos (Denmark)
Suryodaya Urja is the authorized distributor as well as “service partner” for Grundfos in Nepal.
