There is a large potential available for generating solar power using unutilized space on rooftops an wastelands around buildings. Small quantities of power generated by each individual house hold, industrial building, commercial buildings or any other type of building cab be used to partly fulfill the requirement of the building occupants and surplus , if any ,can be fed into the grid. The distribution companies will allow power to feed into the grid and extending net metering facility to the consumers.

In grid interactive rooftop or small SPV systems , the DC power generated from SPV panel is converted to AC power using power conditioning unit and is fed to the grid. The generated power during the day time can be utilized fully by powering captive loads and excess power can be fed to the grid as long as grid is available. In case , where solar power is not sufficient due to cloud cover or during the night hours, the captive loads are served by drawing power from the grid. The grid interactive roof top solar system cab work on net metering basis wherein the beneficiary pays to the utility on net meter reading basis only.

Broadly, the solar water heating systems are of two categories. They are: closed loop system and open loop system. In the first one, heat exchangers are installed to protect the system from hard water obtained from bore wells or from freezing temperatures in the cold regions. In the other type, either thermosyphon or forced circulation system, the water in the system is open to the atmosphere at one point or other. The thermosyphon systems are simply and relatively inexpensive. They are suitable for domestic and small institutional systems, provided the water is treated and potable in quality. The forced circulation systems employ electrical pumps to circulate the water through collectors and storage tanks. The choice of system depends on heat requirement, weather conditions, heat transfer fluid quality, space availability ,annual solar radiation, etc. The SHW systems are economical ,pollution free and easy for operation in warm countries like India.

FLAT PLATE COLLECTOR(FPC)BASED SOLAR WATER HEATERS:

The solar radiation is absorbed by flat plate Collectors which consist of an insulated outer metallic box covered on the top with glass sheet. Inside there are blackened metallic absorber (selectively coated) sheets with built in channels or riser tubes to carry water. The absorber absorbs the solar radiation and transfers the heat to the flowing water.

EVACUATED TUBE COLLECTORS(ETC)BASED SOLAR WATER HEATERS:

The solar radiation is absorbed by flat plate Collectors which consist of an insulated outer metallic box covered on the top with glass sheet. Inside there are blackened metallic absorber (selectively coated) sheets with built in channels or riser tubes to carry water. The absorber absorbs the solar radiation and transfers the heat to the flowing water.

Submersible Solar Pumps lift up to 650 feet and fit in a 4" or larger well casing and are used when the water supply is more than 20 feet from the surface. They can operate directly off solar panels, batteries, or in some cases, an AC power source. Surface Solar Pumps are good for applications with shallow wells, ponds, streams or storage tanks. They are best if the water supply is 20 feet or less from the surface. Linear Current Boosters for Solar Pumps (LCBs) allow the pump motor to run longer during the day by translating additional voltage to necessary current during periods of low sun. We offer Pump Accessories such as filters, valves, and strainers, as well as dry run and float switches and a small selection of submersible wire.

How do I choose a Solar Pump and the Solar Panels to power it?

SELECTING THE SOLAR WATER PUMP:

Solar water pumps can be used with ponds, streams, or wells (generally 4-6 inch well casings). If the water level is lower than 20 feet and the solar pump will need to lift more than that, a submersible solar pump will work great and can lift vertical distances of up to 700 feet. Surface solar pumps can use suction to draw water vertically about 10-20 feet. However, once they have lifted that relatively small amount, surface solar pumps can then push water great distances, like 200 feet or more!

SELECTING THE SOLAR PANELS:

The solar panels powering the solar water pump are sold separately. Each manufacturer provides a graph or table showing how many watts of solar panels are needed to produce the desired water flow. Once you have selected the appropriate type and size of solar pump, use that graph to calculate the correct watts of solar panels. The solar pump and the amount of solar panels needed both depend on how many gallons per day (GPD) or gallons per minute (GPM) you want to pump and the vertical head the pump needs to overcome. Call us to get friendly, technical advice to help you design your Solar Water Pumping System.

Should I use Batteries with my Solar Water Pumping System?

Most solar water pumps run directly off solar panels (PV direct) and do not require batteries. Using batteries may complicate an otherwise straight forward application. Instead of storing electricity in batteries to run the solar pump at non-sunny times, most people prefer to store the water in a holding tank. This results in the same effect, water when you need it, with less cost and less complexity.

Applications:

• Irrigation & Agriculture Pumping
• Drinking water in villages for Individual or Community
• Industrail Pumping
• Effluent treatment plants
• Drip Irrigation
• Resorts & Farm Houses

So, you've thought about whether or not living off the grid is right for you; you know that it means no more utility bills and generating all of your own power, but what's involved in that? It isn't as easy as slapping a few solar panels on the roof and calling it good; when it comes to generating off grid power, there are a handful of methods that can combine to generate all the energy you'll need to live comfortably off the grid.Plug in to off grid power with solar electricity.
Solar power is probably the one that jumps to mind for most of us when it comes to off-grid energy. The sun-powered option, which includes photovoltaic solar panels, an inverter and batteries, can provide lots of electric power (especially if you get a lot of solar exposure where you live) for a long time, without any moving parts and a little maintenance. The downside, at least for now, is the cost: it is rarely cost-effective to power an entire home entirely with solar, even allowing for several decades for a positive return on the investment. Add to that the wide variance of solar exposure by location (see the map for an example) and the fact that solar only works when the sun is shining, and it's easy to see why solar remains a part of the answer, and not the whole thing.

• Environmental concerns—a desire to use less energy and make as much as possible from renewable sources.
• Independence from the electrical utility for philosophical reasons or to eliminate vulnerability from utility outages.
• Political/social values, such as taking responsibility for your energy impacts.
• Cost—depending on how far you are from the grid, it may make economic sense to stay disconnected.
