How does Solar Energy work?

Solar power is clean green electricity that is either created from sunlight or from heat from the sun. Having solar electricity in your home usually means setting up a solar photovoltaic system on your roof. Discover more in our solar energy education sections ahead. Definition of photovoltaic: Photo = “light” and photons = energy particles coming from sunlight; voltaic = producing a voltage or volts. Abbreviation = PV Solar energy is a renewable free source of energy that is sustainable and totally inexhaustible, unlike fossil fuels which are finite. It is also a non-polluting source of energy and it does not emit any greenhouse gases when producing electricity. The solar electricity that is produced can supply your entire or partial energy consumption.

HOW DO SOLAR PANELS GENERATE ELECTRICITY?

The amount of sunlight that strikes the earth's surface in an hour a half is enough to handle the entire world energy consumption for a ful year. Solar technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or by concentrating it with mirrors. This energy can be used to generate electricity or be stored in batteries or thermal storage.

Solar Rooftop

Moving towards Sustainable Energy will not only Substantially contribute towards energy conversation, reduced bills but will also boost up the morale in many aspects:

  • Solar Is the Future; Generate your own power by Soaking the Sun.
  • Say Good Bye to immensely high bills.
  • Contribution towards the environment.
  • A Investment with lucrative returns and Increases the value of your property
  • Easy maintenance and a long-term solution

If your roof is not having any shade from adjacent buildings, trees etc., made of RCC and its structure is not delicate then your roof is suitable for installation of a solar plant.

This would depend on various factors such as the shadow-free area available, the orientation of the roof etc., however, as a thumb rule, we can assume 1KW plant requires 12 sq. meters (120-130 sq ft) of shade-free area.

A 7kW to 10kW plant would suffice for a house with an electricity consumption of 800-1200 units a month.

Amplus uses non-penetrating structures which are mounted without any puncturing. In case any insertions are needed, we use chemical agents which guarantee waterproofing and no leakages. Thus, the integrity of the roof is maintained. The load of the entire solar plant is about 10-15 kg/square meter and can easily be taken by any roof.

No, you can install solar if you stay in an independent house

On an average, every 1 KW setup produces 1300 to 1500 units in a year. This may, however, vary based upon the location of the plant, seasonal factors, surroundings and shadow-free area available.

Technically yes, a solar plant can meet your entire power requirement if it is backed by the battery energy storage system (BESS). But practically, where the power requirement is higher it would be recommended to use solar in sync with the grid. When in sync, priority is automatically given to the solar power to be consumed first.

The Solar plant will generate electricity only during the sunny hours, typically between 6am to 6pm and will not generate any electricity during the night.

The RoI lies in the 15%-30% depending on the system size and the structure you decide to install. Our 10kW product will help you save around Rs.45 lakhs in its lifetime.

Output from Solar PV system is dependent on intensity of light and duration of the day. In rainy and winter seasons, output is slightly lower but still the system works smoothly as sunlight is available most of the time.

A solar system requires minimal maintenance as there are no moving parts. While panels come with 25 years warranty, individual components have different warranties. Regular cleaning of the panels, once in 15 days, is enough for optimal performance of the system.

The panels come with 25 years warranty. 10 years for 90% performance and subsequent 15 years for 80% performance, the inverters come with a 5 year warranty which can be extended by AMC. We have AMC packages which cover upto lifetime of the product. You can purchase to safeguard your entire system.

You can either pay upfront for the system or pay in EMIs starting at Rs.3040/month for a 3kW Atrium.

You’ll need to have a site approval, feasibility test, and net-metering agreements with the DISCOM. The approvals vary from state-to-state. All the applications and approvals are covered by us.

Grid Tied System

This system works only with the electricity grid without batteries. Although, this system has no power back-up but is much cheaper and has no recurring cost. Government backed subsidies reduce the cost further. This system is ideal for cities where there is little to no power cut

Off Grid System

This system works without the electricity grid and has power backup options. This is ideal for cities where there is no connection to the grid and places with frequent power outages.

Hybrid System

As the name suggests, it is a combination of Off Grid and Grid Tied system. It works as a Grid Tied system when electricity is available and works as Off Grid in case of power cut. It has batteries to store energy. It is the most expensive of the 3 systems. It is ideal in cities where there are frequent power cuts.

You can either pay upfront for the system or pay in EMIs starting at Rs.3040/month for a 3kW Atrium.

Net-metering is a principle through which your electricity units are counted by subtracting the number of units you fed back to the grid from the total number of units you consumed from the grid. Your solar system generates electricity units which, if used, reduce the electricity import from the grid thereby reducing your total count of grid units consumed, and, if not used, are fed back to the grid which reflects in your electricity bill as reduction in the number of units consumed. We have a unidirectional electricity meter installed in our homes. A net-meter is a bidirectional meter which moves according to the grid units being imported and renewable energy being exported to the grid.

Installing a 10kW rooftop solar system is equivalent to planting 8600 saplings over a lifetime of 25 years.

Solar Water Heater

Solar water heaters can operate in any climate. Performance varies depending, in part, on how much solar energy is available at the site, but also on how cold the water coming into the system is. Only during rainy season you will need a conventional backup system (Electric).

Due to the smoothness of the glass tube, the surface is not easily susceptible to scaling. Also, the large diameter of the tubes ensures that minor scaling does not impede the efficiency of the system.

Solar Water Heaters once installed requires very little maintenance. Maintenance involves wiping the dust deposited on the glass surface once in 5 days. Wiping the glass every day will help increase the efficiency of the system. Other important thing to be taken care of is to see that the main cold water tank from which water is supplied to the solar tank is always filled up to the level. Use of Automatic Level controller can help in maintaining an optimum level of water.

There is a range of pressurised systems available to cater to high pressure bath fittings.

system is very easy to install and integrate with all kinds of existing plumbing systems without any breakage to existing plumbing. Our installation experts will visit your site and provide you with a detailed plan on how the system can meet your requirements.

A 100 litre system, the average size of a household of 3 – 4 people, can prevent emissions of 0.4 to 1.0 tonnes of carbon dioxide per year. The reduction in emissions of carbon dioxide (one of the major green house gases) can positively help in slowing down the pace of global warming.

ETC based solar water heaters do not need significant maintenance. The collector tubes may need annual cleaning to remove accumulated scale and sediment deposits at the bottom.

The glass used to make these tubes is not ordinary glass but very strong boro-silicate glass, which enables the tubes to resist hail stones as big as 25 mm (1 inch) diameter size.

Normally, we have ready stocks of the standard sizes in multiples of 100 litres. Special sizes can be made on request and will take more delivery time.

The broken tube will have to be replaced by our team. In case of water leaking out of the system from broken tube, please shut the inlet and outlet valves and inform us at the earliest so that your system can be put in order without any delay.

The Solar Water Heating System has an inbuilt option of electrical back-up, and so no extra geysers are required in the bathrooms.

In such a case, instead of a single large system, a number of smaller systems can be installed which have same total capacity as desired. These systems can be placed at locations closer to the use points, thus minimising the piping cost and the wastage of hot water too.

The ETC technology is almost a decade old and thus not so new! This technology, though much superior and suitable than FPC technology, could not take-off being more expensive than FPC technology. It will be obvious that the only advantage FPC ever had over ETC was lesser price. But NOWADAYS, with recent worldwide advances in mass production techniques of evacuated tubes, ETC based systems are more cost effective than their FPC counterparts. In other words, FPC systems are as obsolete as typewriters in the computer age.

FTC means Fixed Temperature Control. The operation of the circulation pump of forced flow system needs to be controlled to avoid pumping of cold water into the hot water storage tank. In FTC control, it is achieved by monitoring the temperature at the outlet of the collector. The pump is switched ON only when the outlet temperature is higher than the SET temperature. If the temperature falls below the SET temperature, the pump is automatically switched OFF.
