Inputs on Solar water heater

[magblr]

Hello All,

Been busy with construction and have not been here for quiet a while. I have reached a stage on deciding solar water heaters.

1) We are 6 people 4 adults and 2 kids.
2) 3 bathrooms with geysers fitted already.
My questions here are
1)How many liters on solar is required for us?
2) Should I go for tube or the regular normal cell(glass type)
3)Which are the good brands available in the market and can you rate those based on the user experience and customer support.

A known person suggested me Tata power solar Zing solar water heater 200lts as good one and promised to get @ 53000/- all inclusive is it a fair deal. As most of us know at the fag end of project we all have budget constraints is there any other cheaper options with good quality.

Awaiting your response.

Regards,
magblr

200L is good.. check EmmVee solar as well as they r good. we have one since last 5 yrs now n no issues. On the price front, 53k appears to be on a higher side for a flat plate model. I would suggest you not to go for the tube model due to inherent risks involved & vaccum loss issues. Not sure what is the status of subsidy nowadays. Pl check.

Actually Government has removed the Solar subsidy sometime this year. So all solar water heaters have become expensive.

Anyone knows a vendor or the current price of Bosch solar heater?

Is really Solar heater Worth investing? Since investment cost is high where we can pay electricity bill for 17 years
Assuming 1 lakh is investment vs paying INR 500 pm towards hot water for a family of 4. Can somebody justify?

Now a days, 200 lts heater will cost you 20-25 k. If have left the suitable provision for plumbing, you don't have to do much in connection. It will pay back in 5 years

I have 2 solar heaters from Supreme Solar , which are EVT (Tube Type). The efficiency of the flat plate collector drops with respect to the water quality and deposits over the years. hence my recommendation is to go with the Tube type solar.
For your requirement 200 L will be sufficient , but in case you feel the need for more , you can have 2 connections , 1 100 L and 1 200 Lt solar.
