On-Grid Systems are solar pv systems that only generate power when the utility power grid is available. They must connect to the grid to function. They can send excess power generated back to the grid when you are overproducing so you credit it for later use.
These are are simplest systems and the most cost effective to install. These systems will pay for themselves by offsetting utility bills in 3-8 yrs.
These systems allow you to store your solar power in batteries for use when the power grid goes down or if you are not on the grid. Hybrid systems provide power to offset the grid power whenever the sun is shining and will even send excess power to the grid for credit for later use.
Provides power for your critical loads when the power grid is down.
When an aerogenerator and an SPV system are interfaced, the power generation from these is mutually supplemented and the resultant hybrid system offers a reliable and cost-effective electric supply. The wind-solar hybrid system mainly consists of one or two aerogenerators along with SPV panels of suitable capacity connected with charge controllers, inverters and batteries to supply AC power. Therefore by using energy storage system we can store and use the combined energy generated from the sun and wind.
Presently the standalone solar photovoltaic and wind energy systems are promoted around the globe on a comparatively larger scale. These independent systems cannot provide continuous source of energy, as they are seasonal. The standalone solar photovoltaic energy system cannot provide reliable power during non-sunny days. The standalone wind system cannot meet the constant load demands due to significant fluctuations in the magnitude of wind speeds throughout the year. Therefore, energy storage systems will be required for each of these systems in order to satisfy the power demands. Usually storage system is expensive and the size has to be reduced to a minimum possible for the renewable energy system to be cost effective. Hybrid power systems can also be used to reduce energy storage requirements.
By integrating and optimizing the solar photovoltaic and wind systems, the reliability of the systems can be improved and the unit cost of power can be minimized.
It converts the wind into energy through a rotating wind aerogenerator into DC Electric power which is stored in a battery bank through a charge controller
Convert sunlight instantly into DC Electric power.
Solar charge controllers are an essential element to any solar electric panel system. At a most basic level charge controllers prevent batteries from being overcharged and prevent the batteries from discharging through the solar panel array at night.
A charge controller is an essential part of nearly all power systems that charge batteries, whether the power source is PV, wind, hydro, fuel, or utility grid. Its purpose is to keep your batteries properly fed and safe for the long term.
The basic functions of a controller are quite simple. Charge Controllers block reverse current and prevent battery overcharge. Some controllers also prevent battery overdischarge, protect from electrical overload, and/or display battery status and the flow of power. Lets examine each function individually.
Maximum Power Point Tracking (MPPT) is a relatively new technology that an increasing number of solar charge controllers offer. While MPPT charge controllers usually cost more than traditional solar charge controllers, the gain in overall charging efficiency makes them well worth it in most cases. A relatively new feature is showing up in charge controllers. It extracts additional power from your PV array, under certain conditions
Battery Bank stores the energy generated by the wind-solar hybrid system and helps the user to use it as and when required. Solar batteries provide electrical storage in renewable energy systems. If you want to use your electricity anytime other than when the system is producing it, you will need batteries. So if, during a nice sunny day, your solar array produces a lot of electricity, you’ll need batteries to access that power after the sun goes down. If you have a wind turbine or solar panel array that is connected directly to the electric grid without batteries, you will not use the power they produce during a grid power outage. If you need to be able to use power at any time, you need batteries.
Deep Cycle Batteries used in renewable energy systems are different from car batteries and that difference is critical. Energy is captured and stored, then later consumed, in a regular manner. In a battery-based solar electric system, the energy produced daily by the solar panels is stored in the battery bank, which is then used by loads at night or on lesser sunny day. This repetitive process subjects the batteries to a slow, daily charge and discharge pattern. When properly maintained, a deep cycle battery can last four to 10 years.
Batteries are the heart of an inverter-powered electrical system, storing power for use on demand. The most basic way to draw electrical power from a battery is direct current (DC) at the nominal voltage of the battery. In many countries 230 Volts AC 50Hz is the norm. Using an inverter you will convert battery power (DC) into alternating current (AC) of a higher voltage. DC-to-AC inverters have been around for a long time. Inverters are of 2 types
Inverter is used to feed solar power along with the EB power to the end user.There is no battery used here can be used only during availability of sun
Inverter is used along with batteries, The batteries are discharged through the inverters when there is no power from EB. Mostly used as standby power. Can be used any time.
Existing Electrical Panel distributes wind-solar electricity and utility power to the distribution centres through cables.

The Sun's rays fall on the Collector Panel (a component of Solar Water Heater). A black absorbing surface (absorber) inside the collectors, absorbs solar radiation and transfers the heat energy to water flowing through it. Heated water is collected in a tank which is insulated to prevent heat loss. Circulation of water from the tank through the collectors and back to the tank continues automatically due to thermo siphon principle. A Solar Water Heater consists of a Collector panel to collect solar energy and an Insulated Storage Tank to store hot water.
This consists of flat plate collectors covered by an insulated metallic box with glass sheet on the top to receive sun rays.
In this system the collector is made of double layer borosilicate glass tubes evacuated for providing insulation. The outer wall of the inner tube is coated with selective absorbing material. This helps absorption of solar radiation and transfers the heat to the water which flows through the inner tube. The flowing hot water is then collected in the storage tank. These systems are less expensive and can work efficiently in hilly regions and also in regions where water quality is not very good. These systems are available in multiple of 100 LPD (Litres per day) i.e. 100, 200, 300 LPD etc.
