Solar water heaters are a modern way to get hot and warm water any time of the day for household use.
Solar Street Lights provide low cost illumination and acts as central security in many areas.
This system gets power from solar battery or directly from solar panel and helps reduce your electricity bill.
This is a water lifting system powered with electricity generated by solar panel.
This system will help you to generate electricity at your own home. This is really a cost effective method to generate electricity and provide backups.
A solar water heater consists of a collector to collect solar energy and an insulated storage tank to store hot water. The solar energy incident on the absorber panel coated with selected coating transfers the heat to the riser pipes fitted underneath the absorber panel. The water passing through the risers get heated up and is delivered to the storage tank. The re-circulation of the same water through abosrber panel in the collector raises the temperature to 80oC (Maximum) in a good sunny day. The total system with solar collector, storage tank and pipelines is called solar hot water system.
Based on the collector system, solar water heaters can be of two types : 1.Flat Plate Collectors based SWH and 2.Evacuated Tube Collectors based SWH
The Solar radiation is absorbed by Flat Plate Collectors which consists 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 Collector is made of double layer borosilicate glass tubes evacuated for providing insulation. The outer wall of the inner tube is coatedwith selective absorbing material. This helps absorption of solar radiation and transfers the heat to the water which flows through the inner tube.

Solar street lights are raised light sources which are powered by solar panels generally mounted on the lighting structure or integrated into the pole itself. The solar panels charge a rechargeable battery, which powers a fluorescent or LED lamp during the night.
Based on the photo voltaic panel integration, solar street lights can be of two types : 1.Solar Steet Lights and 2.All-in-One Solar Steet Lights

Extracting water from a source (well, pond, river, storage tank…) using the sun as your energy supply is called solar water pumping. Your solar panel will transform the sun’s energy into electricity (DC), the electricity is then converted into mechanical energy by the motor your DC water pump.

Solar power is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV), indirectly using concentrated solar power, or a combination.
A SHS typically includes one or more PV modules consisting of solar cells, a charge controller which distributes power and protects the batteries and appliances from damage and at least one battery to store energy for use when the sun is not shining.
They contribute to the improvement of the standard of living by:
On-grid or grid-tie solar systems are by far the most common and widely used by homes and businesses. These systems do not need batteries and use either solar inverters or micro-inverters and are connected to the public electricity grid. Any excess solar power that you generate is exported to the electricity grid and you usually get paid a feed-in-tariff (FiT) or credits for the energy you export.
An off-grid system is not connected to the electricity grid and therefore requires battery storage. Off-grid solar systems must be designed appropriately so that they will generate enough power throughout the year and have enough battery capacity to meet the home’s requirements, even in the depths of winter when there is generally much less sunlight.
The high cost of batteries and off-grid inverters means off-grid systems are much more expensive than on-grid systems and so are usually only needed in more remote areas that are far from the electricity grid. However battery costs are reducing rapidly, so there is now a growing market for off-grid solar battery systems even in cities and towns.
Modern hybrid systems combine solar and battery storage in one and are now available in many different forms and configurations. Due to the decreasing cost of battery storage, systems that are already connected to the electricity grid can start taking advantage of battery storage as well. This means being able to store solar energy that is generated during the day and using it at night. When the stored energy is depleted, the grid is there as a back up, allowing consumers to have the best of both worlds. Hybrid systems are also able to charge the batteries using cheap off-peak electricity (usually after midnight to 6am).
