(1) Stay Away from Factory Rejected Solar Module Sellers
I have been active in Solar and Agricultural industry for quite a long time (6 years) , and recently have I come across some VENDORS, who are Selling Factory Rejected Solar Panels at Cheaper price at Rs. 30/Watt. Even cheapest Chinese made come at Rs. 45/Watt not inclusive tax. And I saw a forum right here where people were queuing in to buy that stuff… Make Sure You Don’t buy from such sellers, they do give fake certificates and fake warranties and even fake/rejected solar modules but that would be like throwing your money on Garbage,
(2) Sizing is Essential: over sizing or under sizing can leave you with a mess
While Going Solar, it’s an entirely new paradigm, so Sizing becomes very crucial part of the project as much as every component. If you are currently using a 5hp submersible pump to get water from 100feet below the bore well, it is not important that Solar Water Pumping Will require exact 5hp pump. Don’t go with the formulae that I am running a 5hp motor so . my solar water pump requirement is 5hp.. Get your water consumption pattern sized up. Your irrigation water requirements depends on crops you are currently growing, you may grow in future, and your soil type and soil moisture contents, and rain water availability. It’s a very complex calculation, so I wont go in details, but note, that there are many factors that play role in your irrigation water requirement. And your water pump should confirm to this needs. Take into account the free or nearly free power you are usually getting from government.
Imagine a scenario where you spent say 10lacs for running a 10hp submersible pump. Now suppose you pumped daily with your old 10hp pump for almost 3 hours daily. now here your solar pump is capable of running from Sun Rise to Sunset…nonstop. So it is producing more water than you currently need it. you have to close the pump after 4 hours of pumping, you either have to build a tank, but how much water that tank will hold? For how many days, how huge will you make the tank? Now you realize that you really didn’t need the extra power. And you are not even able to use almost, all the free power that government provides. And there are limited options, here. Either to sell half of your solar panels at loss, or to move them to your home, where you could use that power for your home electricity needs.
(3) If you have doubts start small
Don’t go huge, at first Attempt: if you try asking anyone, including me for 5hp 10hp motors, the project cost is going to be over INR 5,00,000 and that itself may disappoint you from thinking twice about Solar, and that way you will not be able to harvest golden fruits of Solar Energy. so start small. go after keeping in mind your present and future water consumption. go with someone who can SEE what is your Current Water Consumption Pattern/ what is your Electricity Consumption Pattern, and based on That can help you size your project in such a way that you will not be fearing where to stock extra water, or what to do with extra power that your huge solar panel array produces, while you can’t even use it…
Remember you can always go up, but there are limited options for Coming down With Solar:
Even if you need five hour pumping daily, with a 5hp motor, my friend, first go with a 2hp solar set. This will help you when govt. grid will fail, this will help you when govt. will impose fierce cuts on power. And in any case when government won’t be able to supply you with the free power. Still we at Bati Energy recommend our customers that they use as much government power as is given to them. You can always add solar Panels in your Solar Array and Run higher capacity Submersible pump
(4) You are not buying a USE and Throw item.
You are investing for a minimum of 25years of power Security. Stuck with this important information, there are sooo many factors, very important factors that will come into play for deciding right solar panel for your need, your environment, your location, and your budget, and your farm.. There are also technical factors, that will be quiet important in choosing the right panel for your project. keep this in your mind, that you will not go with any solar panels or solar water pumping system providers, many businesses are in business simply to make money out of your aspiration, and very few are there who can guide you thoroughly on your project, who can Size up your water requirement for irrigation purpose and who will understand all your needs in Every possible scenario and details, and based on that will provide you a customized solution.
(5) There is no Ready-Made with Solar
You want a pair of clothes and you can buy in the market ready-made. It is not the same way with solar. Solar Radiation changes according to locations, seasons, times of days and with many other factors, so there is simply no ready-made thing here that you can pay and buy. Customization is extremely important for not only solar water pumping system but any solar power project. The pump made for Gujarat will only be able to work at 70-80% capacity in Delhi. There simply is no ready made with Solar. The solar panels which are made for cold regions will not perform better in Desert.
There was a heartfelt need, that farmers are wrongfully directed in solar water pumping industry. And there in the market, solar panels are available that won’t last beyond 5years. Therefore Ii thought I should at least try to make you aware how Solar Works.
