Installing Solar Water Heater for Home – Information and Costing

Solar Water Heater

Recently we installed 150 Litre Solar Water Heaters at our terrace. Below are the Information, photos and costing for Installation of Solar Water Heater.

When you decides to install solar water heater, you need to consider following factors,

  • How many people are there in your home who will be using hot water ?
    • Based on this the number of Liter water required needs to be finalized. Lets say, you have 3 people at your home and each one will use average 50 Ltr of hot water each day, then you will need to purchase 50*3 = 150 Ltr solar water heater.
  • What is your budget for purchasing new solar water heater ?
    • As you might already be aware, solar products needs somewhat more initial investment, so you needs to enquire different brands available in market and compare their pricing and features for same model of solar water heater.
  • What is the warranty of the solar water heater and how you will contact them in future for servicing ?
    • Most of the solar water heaters are long durable, and comes warranty of 5-7 years. So you needs to get proper warranty information and how they will provide the service for future in case some issues. Once installed, the most common issue you might face is due to hardened water. But if you are ready to get solar water heater serviced once in one / two year then no issues.

The common pricing for installing solar water heater will include following things,

  • Solar Water Heater Price + Tax
  • Transportation Cost
    • If you have agreed to pay for transportation cost of solar water heater ( tank + pipe etc ) from company to your home, then we need to account this cost.
  • Plumbing Material and Service cost
    • This will be an additional cost which includes purchasing all the pipes ( hot water pipe, cold water pipe ), valves etc and payment of plumber services. If your current cold water tank is at same surface level where are going to install water heater, then there will be additional cost to increase height of cold water tank, so that daily transmission of cold water to solar water heater and hot water from water heater to your bathroom tap can be automated without daily efforts required to fill solar water heater tank.

The Solar Power Tree – An Intervention by Indian Scientist aimed at Utilizing Minimum Land to Harness Maximum Solar Energy

solar_tree

CSIR-CMERI,Central Mechanical Engineering Research Institute (CSIR-CMERI), Durgapur, West Bengal has designed and developed a “Solar Power Tree” to harness maximum solar energy utilising minimum land – In general, it requires about 3.5 acres of land to produce 1 MW of solar power. For any state in the country to survive on green energy there will be requirement of thousands of acres of land. The acquisition of land is a major issue for private sector industry. Solar Power Tree addresses the biggest hurdle of land requirements to gainfully utilise solar power.

Solar Power Tree is an intervention against land constraints. It harnesses solar energy for producing electricity with an innovative vertical arrangement of solar cells. It thus reduces the requirement of land while keeping the land character intact. It even enables utilisation of the cultivable land for solar energy harnessing along with farming at the same time.

The Salient Features of the Solar Power Tree are:

  • It takes much less land of only 4 sq ft for a 5 kW Solar Power Tree as compared to 400 sq ft of land required in case of the conventional Solar Photovoltaic layout;
  • It holds the panels at a higher height – thus gets more sun (by 1 hour) in a day in comparison to that in conventional layout on ground; Thus, it is possible to harness 10-15% more power;
  • It is facilitated with water sprinkler at the top for self-cleaning of panels;
  • The paddy lands or agro-gardens or roads can be utilized for production of green power keeping land scape/cultivation unaltered;
  • Applicable for both rural and urban areas.

In future, it is possible to harness 10% more power by rotating panel direction twice in a day by using a module that aligns itself with the movement of sun. Also, aesthetic aspects would be incorporated in the design of solar tree to landscape the land.

The Specifications for 5 KW Solar Power TREE are:

  • Peak Power: 5KW;
  • Full Load Capacity: 60% of the Peak;
  • Battery Back Up: 2 hrs. (Full load);
  • Cost: INR 5 Lakh;
  • Footprint: 4 sq. ft.;
  • Arial Span: 25 ft. Dia,
  • Warranty: Panel: 25 Years.

The technology developed under the leadership of Dr. SN Maity, Chief Scientist, CSIRCMERI, has been licensed to: M/s Vibes Solar Solution India LLP, Kolkata. The process is under way to license the technology to more companies.

Frequently asked questions ( FAQ ) regarding solar

solar

Q. Solar panels are not worth the cost because they don’t work when it’s cloudy or at night. ?

Ans-> Solar power works even in cold or cloudy places, and new tools are allowing us to use it even when the sun goes down!
Because of the way the technology works, solar panels are just as effective—and usually more effective— in cooler temperatures as in hot ones. And while it’s true that clouds can affect the efficiency of solar panels, they can still produce enough power to be viable sources of electricity. Germany, for example, is a country that is not particularly warm or sunny, but is nevertheless the world leader in solar energy, generating more electricity with solar than nuclear power in July 2015.
