Types of Solar Energy used


Today there is a cheaper solar water heater price in Chennai and easier answer that hybridizes consciousness and convenience.  Taking a few minutes to understand grid-tied, net-metered, roof-mounted solar systems is worth the while.



Grid-tied: this means the energy a  solar water heater price in Chennai  solar array produces is directly linked to the electrical  utility grid.  No pricey batteries necessary!  No maintenance or  solar water heater price in Chennai  upkeep.  You can think of it as the grid serving as your storage capacity.


Net-metered: For every kilowatt solar water heater price in Chennai  hour of energy you produce during the day that you don’t use, you are credited one kilowatt hour of energy to use at a time when you are not producing as much as you need, for instance at night. This is a 1:1 ratio.  In Delta county Colorado 1 kilowatt solar water heater price in Chennai hour of electricity costs 10.3 cents.  For every kilowatt hour you produce you receive the equivalent of 10.3 cents of electrical use.  (Let’s be clear- you will not be paid 10.3 cents/kWh by the utility).  Think of it like this: When you use a kilowatt hour your meter tics forward one count.  When you produce a kilowatt hour your meter literally tics backward one count.  (Currently, if you have a solar water heater price in Chennai  yearly annual overage, DMEA will pay you for each and every kilowatt hour you overproduced at their wholesale avoided cost, 7.5 cents/kWh).



Roof-mounted: This is usually the cheapest and simplest way to incorporate a solar array on your home or business.  When the price of solar panels was much higher, solar water heater price in Chennai  as little as 3 years ago, it was cost-effective to maximize the production of the array with intricate racking  solar water heater price in Chennai  systems adjustable for latitude, time of year and even down to time of day!  But, hold up, who wants to maintain so many movable parts requiring  solar water heater price in Chennai  maintenance.  Consider adding a couple of more panels to your simply laid out system flush-mounted to the roof and you will save in the long run. Nowadays, solar arrays can face anywhere from due east to due west and only lose 15% efficiency at worst!

It is optimal for solar panels to face South so that they get sunlight throughout the day.  solar water heater price in Chennai  Solar Panels usually come in standard 250Wp (Watt Peak) to 300Wp panels for larger home installations. Even some medium to large installation use multiple 74Wp or 100Wp panels. It solar water heater price in Chennai  depends on the installer, the space availability and the system design.

3. Measure how much electricity you use everyday

A 3000Wp of solar panels, charged solar water heater price in Chennai  through the day, can provide about 8000 Watts of power, subtracting inefficiencies. A typical Solar Cell provides around 0.5 Volts and around 36 and 72 Solar Cells make up a typical solar panel which implies 12 and 24 Volts. With one panel, you can   solar water heater price in Chennai choose a combination you want to power – all fans or all lights or just the kitchen. The first step is to study your electricity bill. Always go for genuine suppliers. A regular 2/3BHK household using a microwave, will need about 15,000 Watts of power everyday.

The India Solar Homes from Bridge to India can estimate your solar power cost by looking at your State,  solar water heater price in Chennai  your last months electricity bill, power backups you have and reliable .


4. How much will you pay for the sun?

Though solar power can cut down your electricity bills, it does require some installation cost and initial investment.  solar water heater price in Chennai  Figure out how much you can spend and plan your solar implementation accordingly. The cost of solar varies from Rs.40,000 to Rs.6,00,000 depending upon how much of the energy you would like to generate from solar. You can calculate your solar water heater price in Chennai  cost by following method (simplistic way of arriving at approximate)
Calculate your approximate load (in watts) for a day

Divide it by 3 (avg. no of hours of sun)
Multiply by Rs. 110
Eg: For 1800 Watts a day, you need solar panels that can produce 600 Watts. The cost will be 66,000 for this installation.

5. Servicing and maintenance

The life of a solar panel is 25 years. Solar panels have no moving parts or electronics and require practically no maintenance throughout its life of 25 years or so. While buying, solar water heater price in Chennai  ensure you are picking up reliable equipment from genuine certified suppliers. Question the dealer about how they have built the structure of the panel and what is the guarantee.

6. Get a good battery

A typical solar power installation has 4 components: the solar panels, the charge controller solar water heater price in Chennai  (to convert DC to AC), battery charger (for storage) and the actual equipment.


Make sure you buy your battery from solar water heater price in Chennai  a known brand and it is kept at an airy space otherwise will get heated up and the life will get reduced.

Advantages and Disadvantages of Solar Energy


 Advantages :

What is Solar Energy ????

Solar power is energy from the sun. "Solar" is the Latin word for "sun" and it's a powerful source of energy. solar water heater price in Chennai Without it, there will be no life. Solar energy is considered solar water heater price in Chennai as a serious source of energy for many years because of the vast amounts of energy that is solar water heater price in Chennai made freely available, if harnessed by modern technology.

Energy From The Sun

It is renewable!


It is considered 'Renewable Energy' because...

solar energy kidsThe technology solar water heater price in Chennai used to convert the sun's power into electricity does not produce smoke (carbon dioxide and other air pollutants).

solar energy kidsTapping the sun's energy does solar water heater price in Chennai not usually destroy the environment.

Unfortunately, the sun does not available in the night, and in some days, clouds and rains and other natural  solar water heater price in Chennai conditions prevent the sun's powerful rays to reach us. This means that it is not always available. This a why we cannot rely on solar energy alone.


Solar cells
Solar cells are devices that convert light energy directly into electrical energy. In these cells, there are solar water heater price in Chennai semiconductors (silicon alloys and other materials). You may have seen small solar cells on calculators  solar water heater price in Chennaior some mobile phones. Larger arrays of solar cells are used to power road signs, and even larger arrays solar water heater price in Chennai are used to power satellites in orbit around Earth. Solar cells are also called photovoltaic cells or PV devices.


Solar panels
Solar panels are different  solar water heater price in Chennai to solar cells. Solar panels do not generate electricity directly. Instead they heat up water directly. A pump pushes solar water heater price in Chennai cold water from a storage tank through pipes in the solar panel. The water is heated by heat energy from the Sun and returns to the tank. They are often located on the roofs of  solar water heater price in Chennai buildings where they can receive the most sunlight.

Solar Thermal Power Plant There is also the  solar water heater price in Chennai Solar Thermal Power Plant. Here, a concentration of the sun's energy by many panels is used to heat solar water heater price in Chennai  up water into steam, which is then used to turn turbines to produce electricity.

Power stations of this nature solar water heater price in Chennai usually need a lot of space to capture a lot of the sun's energy!

The Parabolic Trough System uses this kind of system. Here, troughs are designed to direct the sun's energy solar water heater price in Chennai  to absorber tubes as long as the sun is up.


Many of these Parabolic troughs  solar water heater price in Chennai are installed to collect massive energy for the rods to heat water to turn turbines.

Other less common methods that  solar water heater price in Chennai use the Solar Thermal Power Plant system are the Solar Dish and The Solar Power Tower.
