load of 6 Fans, 8 Tubelights, 1 Fridge, 1 LED TV. would roughly come to 1000W ... it may be lesser as you wont use everything at the same time but having a little spare room is always recommended, you can use the excess for running a juicer or make milkshake or even run a washing machine in morning and afternoon times using same load, as its still excess power..
to get 1000W power from solar, you would need - A ups/inverter capable of at least 1500W. not 1500VA....solar panels ..frames.. batteries,.. wiring..
1 - Panels of atleast 2000W, as sunlight is variable in all times of day and peak power is between 10am to 3pm, at all other times you would get less light and thus less power, sop to not only sustain a constant 1000W, plus charge batteries, but also be able to secure enough light in morning and eve, 2000W should be your target. that alone would cost you around 2 lac including installation. in case you go lower, then reduce your consumption as well. a fridge alone could go as high as 400W, exclude the fridge or run it on peak power hours i.e continuous 5-6 free power hours and rest on wapda and you can manage your load in 1500W panels or less.
2 - a hybrid inverter with your requirement of grid tie or grid feed, in your budget is impossible. infini is the cheapest option and that alone costs over 1.1 lac. an Axpert MKS 3Kva inverter is around 50-60k, and even though its not a true hybrid, nor is it good at harvesting max energy from solar panels, it does the job fairly well for what you require.
3 - the cheapest alternate is the simplest one.. panels connected to Controller to batteries and ups... if you already have a ups and batteries, your cost goes a lot down.. a good controller would be around 30k, including option for future expansion as well. it will also get more power from panels than either MKS or even infini.. it will prolong your battery life, and run everything connected to your ups all day.
4 - the only constant in the entire scenario is the frames and installation plus wiring.. since your load is small, you can easily do away with 16mm DC wires, and the rest can be well managed with either 3/29 or 7/29 if 3/29 isnt good quality copper wire. the quality of wire used is the most important thing.. save money on this and you suffer after 3 years times, even earlier. since this is going to last you at-least a good 7-8 years + time, so wiring should be the best quality you can afford. frames for mounting panels would cost between 4-5k for a 2 panel mount. add up all these prices and installation alone can easily go around 25-30k. since this is not going to change on yearly basis like batteries, thus investing on these is critical as a one time expense.
A - a panel of 200W will most time provide not more than 150W. it can go a lot down, but rarely higher, consider the total amount of power you need and add 40% to it and thats how much watts panels you need. 60% is average efficiency of panels on the whole day.
B - as long as you have solar connected to your controller to ups / inverter, all day solar will charge your batteries and keep them fully charged, and will provide power to you house all day and even charge your batteries when wapda comes back from load shedding as ups will not charge battery from wapda, solar will. so long term wapda bill reduction as well as free power as well as battery life prolonged from just the controller battery ups system. this is the best option hat comes in your buget.. latter on you can add more panels as you can afford them, as well as add a hybrid inverter next year when budget allows, your current setup will remain the same, only swapping the ups for inverter and even your controller will keep running smoothly along with the new hybrid inverter.
C - Consider replacing your tubelights with good quality LED lights to significantly reduce your load, this will also help in winter when solar power generation is minimal, and while your fridge will run less, and no fans, tube lights will consume around 10x more power than led lights. these cost effective measures can optimise your load buget and investment.
