dear sir/madam, As i have went over many sites,but didnt got the right information that ,what and how my diagram would be done, Today i got your site in search engine while browsing for best solar inverters, Here are (below)my requirement ,which i need to run only on solar system without any backup power,no power required after sunset, I can say running these appliance from 7 or 8am till 5 or 6pm only (1) 1#5000btu 110vac air conditioner rated 515watt,but dont have idea about starting surge.. (2) 2 #evaporative air cooler 220vac consuming 120watt each(240watt both) (3) 1 #ceiling fan 220vac consuming 70 watt (4) 1# 80ltrs refrigerator Please figure me a diagram ,that what type of inverter and what capacity of panel required…and what else is required… Reply your soonest Thankyou

What is ratio of area with power production and cost incurred on it? It mean in area of 1 SqFt or Sqmtr how much energy will be produced and will cost how much?

I am from Deoria UP, I am planning to install Water pump for irrigation completely solar based. since sun hours are around 12 hours days.. it would be suitable to try for one Here is my question. 1. What are things need to setup (lile panel, battery etc).. 2. what would be cost? 3. How long does it lats any annual maintenance etc. Thanks Chandra

I want to ask you what are the top solar epc companies in India and what sort of work/services do they provide?

Dear Sirs,

TN govt has just announced that it expects Germany and/or TN Govt to spend ~1600 Crores on “evaluation” of wind power potential in TN. (I hope here is a mistake in The Hindu reporting this…!)

I am raising a discussion with my academic colleagues on what this money itself will fetch for TN as Solar power in KwH units. We appreciate the folks at TN govt are no fools, and yet we at the University have to be sure what we are doing with tax-payers’ money.

It should be quite simple for you to answer this question at this expenditure level. We would appreciate your advice on this(including the aspect of scaling up at this level of expense) before we do anything more about this project.

Thanking you,
Sincerely,

Hi,

I would like to know the total costing of installing a 1 kw solar panel (off grid). Kindly include costing of all equipment like
a. Controller
b. Inverter
c. Lead acid batteries with preferred voltage 12/24 Volts & type like deep discharge/regular etc.
d. Panel with size type & cost corresponding to suggested battery voltage for poly crystalline / thin film
e. Also life expectancy and output degradation of poly crystalline vs thin film solar cells
f. Additional list of equipment & cost thereof
g. Kindly use solar data for Bhopal, Madhya Pradesh, India.
