Solar water Pumping systems are reliable-do not use batteries for energy storage-easy to use-huge cost savings over Diesel generator used for water pumping.

Solar water pumping systems-unlike conventional AC electricity powered water pumping systems- are possible to be designed only by knowing:
♦ Total dynamic pumping head in meters/ feet.
♦ Expected daily average water requirement in Liters/day or m3/day.
♦ Site location to estimate expected solar resource availability.

The major differences in specifying solar water Pump v/s a Conventional AC submersible pumps are:
♦ Need to specify liters/day output v/s liters/minute/liters hour at the specified/defined pumping head-for Conventional AC Pumps.
♦The dynamic head in turn must be accounted for considering the static lift of water from the source to the discharge point.& the transportation piping friction and other losses, including the draw down levels that actually occur when any pumping is in progress.

Thus one needs to decide carefully the dynamic head in feet/meters that the pump must overcome-or the Installation shall fail.

♦Site's geographical locations to know/assess expected solar resources.

Please contact us giving details of all above, for further information, including sizing and design of the expected installation to make a successful solar water Pumping system installation

Solar Power systems are designed on the principle of daily energy balance-thus:

One must state the daily cumulative energy demand -over a 24 hour day AC or DC or Mixed load’s (kilowatt/Watt hours/day: Load watts x hours/day the Load is required to be ON) kwh/d loads the proposed system is expected to meet.

Since solar energy conversion depends on available solar irradiance, and insolation (incident solar radiation) the knowledge of the proposed installation site is important-to avoid errors of judgments,

Please contact us giving the above load energy demands to be provided from the proposed solar power plant giving site details.

Solar power systems can be designed either stand alone type or Hybrid type.

Stand alone systems are those where except solar energy there is no other source such as Utility Grid-Diesel generator or similar source that is expected to partially meet the load energy demands.

However to design either a stand alone system or a Hybrid system the Load energy and the site details are important to make a design.

A solar lamp also known as solar light or solar lantern, is a light fixture composed of an LED lamp, solar panels, battery, charge controller and inverter. Depending on where and when the lamp is being used, it has various sizes of batteries. The lamp operates no electricity or batteries are required due to the use of solar through the use of photovoltaic panel.

Solar-powered household lighting can replace other light sources like candles or kerosene lamps. Solar lamps use renewable energy with infinity supply and it is cheaper than standard lamps. In addition, solar lamps reduce health risk as kerosene lamps has bad impact on human health. However, solar lamps have high initial cost, weather dependent and the panels can pollute the environment.

Components:
♦Solar cells/Solar panels
♦Battery
♦Charge Controller

Advantages of solar lamp:
♦Easy to install: Solar lamps are easier to install as often they do not have cable. Not having a cable is a huge advantage as sometimes electricity-run lamps are broken due to the cable lines and reduce the chance of broken lamp. Additionally, LED lighting will provide high-quality illumination.

Vistar Electronics Pvt. Ltd, Designs, manufactures supplies- wind solar Hybrid systems to customer specific needs.

Wind generation is possible only by the average wind speed -that must be above the threshold of -minimum average wind speed to start generation from a wind turbine-is actually occurring at a site or is expected to be available.

Vistar assists user to find/access such data for any given site identified by Latitude- Longitude.

Solar Generation on the other hand is more predictable since the conversion technology of solar irradiance to electrical energy is more predictable.

Please contact us for further details giving:
♦ Expected site location.
♦ Feasibility to install at such site a wind generator, and solar generator-SPACE AT SITE, obstructions to wind/solar resource etc.
♦ Expected daily load energy demand at this site-essential to design the Plant capacity vis-à-vis Annual average-daily-available wind and solar resources.
