Why should I go for a Solar Water Heater? What do I save from it?

A 100 litre per day capacity system suitable for 3-4 people can save up to 1500 units of electricity in a year depending on the amount of hot water used. It can also save around 140 litres of diesel in an establishment using oil fired boiler besides reducing greenhouse gas emissions in the atmosphere. Higher capacity systems will save higher amount of electricity/fuel oil besides reducing higher amount of GHG emissions.

How does it work – Solar Water Heater?

A Solar Water Heater comprises of an array of solar collectors to collect solar energy and an insulated tank to store hot water. Both are connected to each other. During the day time, water in solar collectors gets heated which is either pumped or flown automatically on thermosyphon principle to the storage tank. Hot water then stored in the tank can be used for various applications.

What is Solar Water Heater?

A Solar Water Heater is a device which provides hot water for bathing, washing, cleaning, etc. using solar heat energy. It is generally installed at the terrace or where sunlight is available and heats water during day time which is stored in an insulated storage tank for use when required including mornings.

What are Solar Lights?

Solar lights are portable light fixtures composed of LED lamps, photovoltaic solar panels, and rechargeable batteries.

How much area can a solar powered pump system irrigate?

Generally, a 2 HP pump can cater to about two acres of land and a 7.5 HP is said to cater to 10 acres of land, but this data vary depending on the groundwater levels and the type of irrigation required for a specific crop.

How are solar water pumps more useful than conventional electric pumps?
  • Solar water pumps do not require any fuel/electricity to operate. Once installed, solar water pumps do not incur the recurring costs of electricity/fuel.
  • Does not get affected by power cuts, low voltage, single phase problems or motor burning.
  • Can be installed in remote areas where grid electricity is unavailable or diesel is difficult to procure.
  • Easy to operate, and low maintenance costs as solar water pumps have fewer moving parts as compared to a diesel-powered pump and thus, fewer chances of wear and tear.
What is the use of solar water pumps?

A solar water pump is used for extracting water from ponds, rivers, borewells or other sources of water to meet the water requirements for irrigation, community water supply, livestock and other purposes.

Will we face problem of Voltage fluctuation and tripping if heavy loads like AC switched on?

KCP offers Grid tie Rooftop Solar PV Power Plant which matches the frequency and voltage of your Grid and Diesel Generator and synchronises them. The electricity generated by the Solar PV Plant is exactly like the one you are sourcing from Grid/DG and it will be fed in simultaneously with them. Thus, there will be no voltage fluctuations and you can connect any number of heavy loads equipment.

What is the minimum size of Solar PV Power Plant that is installed by KCP?

Our Installation size typically start from around 1KW to MW Scale.

Can all electrical equipment be integrated with solar energy?

Solar energy is integrated into the LT panel of consumer premises, wherein DG, Grid or other generator source would be feeding power as of now. When solar energy is injected, the equipment is unaware of the source from which power is feeding in. Hence it is not possible to segregate the loads on basis of power source.

How do I know that the Solar PV System is working?

It is advisable to install a data monitoring device along with your solar device that will allow you to compare the actual and estimated performance on daily, monthly and annual basis.

Does rainfall affect the performance of the solar panels?

The electricity generation of the plant suffers during Rainy and cloudy days especially during the Monsoon season, but the generation never drops to zero. The loss of generation during monsoon and other rains is already adjusted in the summer season.

In fact, there is an increase in solar energy gain after rainfall as it clears all particulate matter in the sky which scatters light. That is why the sky is very bright after a good downpour.

What is the annual maintenance procedure for a Solar PV System?

The maintenance is not significant. Water can be used to clean the panels – Typically 5 litres of water is required for a KWh.

What is the average life of the Solar panels?

Most panel manufacturers provide a  warranty of 25 years, however there have been plants in operations for 40 years as well

What are the factors to be considered before “Going Solar”?
  • Energy demand and Consumption of power
  • Availability of the shadow free area in your rooftop
  • Budget consideration
Is Solar Energy cheaper than the Energy from Diesel Generator?

Solar power is much cheaper than diesel generators. Today, average power from solar is Rs. 5-7 per KWh (For commercial and Industrial segments) while average power from diesel generator is Rs. 17 per kWh (a litre of diesel generates around 3 – 4 kWh).

Which Solar PV system will be eligible for the Government’s Subsidy Scheme?

Government’s subsidy scheme applies to Grid-Connected Solar PV Systems at Residential, Educational Institutions, Hospitals, and NGO’s. This capital subsidy scheme is only for the Grid-tie system.

What are the Grid Connectivity levels for such systems?

It falls within two broad categories i.e.

  • the projects connected to HT voltage at distribution network (i.e. below 33 kV)
  • the projects connected to LT voltage i.e. 400/415/440 volts (3-phase) as the case may be or 230 volts (1-phase).
In case of Grid failure, is there any chance of shock to the person who is repairing?

In case the Grid fails, the solar power has to be fully utilized or the export to the grid should be stopped immediately feeding so as to ensure the safety of any Grid person/technician from getting shock (electrocuted) while working on the Grid for maintenance. This feature is termed as ‘Islanding Protection’.

What is the function of a Netmeter ??

A Grid-Connected Solar PV System will reduce the power bill due to the export of energy through a net metering provision. Ex: If someone imports (consumes) 1,000 kWh from the Grid and Exports 600 kWh to the Grid in a billing cycle, then The total energy bill will be for 400 kWh (1000 kWh – 600 kWh) accounted by Netmeter.

Net metering/Bi-Directional Metering?

The Grid-Connected Rooftop Solar PV System can work on net metering basis wherein the consumer pays to the Utility on net meter reading basis only. Alternatively, two meters can also be installed to monitor the export and import of power separately. The mechanism based on gross metering at mutually agreed tariff can also be adopted.

What are the advantages of Grid-Connected Rooftop Solar PV System?
  • Reduction in electricity bill
  • Payback period within 4 years.
  • No requirement of additional land.
  • Easier to operate and maintain.
  • Self-consumption of solar electricity.

How much electricity will a Solar PV System produce?

For Every 1 KW installed, Atypical Solar PV System generates is about 1,500 kWh (units) per annum in Tamil Nadu. Actual energy generation depends on the efficiency and tilt angle of the solar panel, weather, grid availability and cleanliness of the solar panels.

How much roof area is required to set up the Grid Connected Rooftop Solar PV System?

About 10 sq.m area is required to set up 1 kWp Grid Connected Rooftop Solar PV System.

What is a Grid Connected Solar Rooftop System and how will it reduce by bill?

In Grid Connected Rooftop/Small SPV system, the DC power generated from the SPV panel is converted to AC power using the power conditioning unit and is fed to the grid. These systems generate power during the day time which is utilized fully by powering captive loads and export excess power to the grid as long as the grid is available. In case, when solar power is not sufficient due to weather conditions or high demand,., the captive loads are fed by drawing power from the grid.

For example, let’s consider a house with an annual consumption of 2000 kWh (units) has installed a rooftop solar panel of 1 KWp capacity. If the rooftop plant produces 1500 kWh in a year, then the house will be billed only for 500 KWh. Further, the house owner can benefit due to the differential electricity slab tariff where higher power consumers are charged more per unit of electricity.  (DISPLAY THE SLAB RATING OF POWER IN TAMIL NADU)

What is a Solar Rooftop System with Storage facility?

If the rooftop system has a battery system for storage facility, then it’s termed as a Solar Rooftop System with Storage facility. The solar electricity is stored in the battery and can be utilized during night when solar energy is not available.

What is a Rooftop Solar PV System?

In a rooftop solar PV system, the solar panels are installed in the roof of any residential, commercial, institutional, housing societies, community centers, government organizations, private institutions and industrial buildings.. This can be of two types

  • Solar Rooftop System with storage facility using battery, and
  • Grid Connected Solar Rooftop System
What is a Solar PV (Photo-voltaic) System and how does it work?

PV, short for Photovoltaics, is  the process of converting light (‘photo’) directly into electricity (‘voltaic’). Simply put, a Solar PV system is a power station that generates electricity from sunlight. The main components of a Solar PV system are:

  • Solar Modules : Solar panels consist of a group of small cells made from semiconductor material. When the sun’s light falls on the modules, it excites the electrons, thereby creating direct current (DC).
  • Storage Battery : The best way to use solar energy is to consume it while it is being generated. If the requirement is to store this power and consume it in non-sunny hours, then solar energy can be stored in batteries for later consumption.

Solar Inverter : The DC electricity goes into an inverter that converts it into alternating current (AC). We use AC for running our household or office or factory equipment.
