Giving a Gift of Solar to Family in Karachi: Options?

[TNT]

Hello,
[Posting in the Economy section of PDF because the topic is, IMHO, more related to Pakistan's economy than to Social discussion; and hopefully this will stir some debate and maybe even some economic activity in Pakistan.]

I have some $ which I'd could invest. Up to $80,000 as of now. One investment I'd like to make is to make my family home in Karachi as much solar powered as possible and I am willing to put in a good bit of money--but only for quality stuff. It will be a gift to the family and indirectly to Pakistan's economy.

Now to the house: It is on 1000 sq yards with three stories. Including resident servants, I'd say about 16 people live there. Lots of rooms. And a huge roof which gets a lot of sun--not many surrounding tall buildings.

What are my options for finding the right companies? What kind of system is suitable? Time frame for the installation? Any red tape from the govt?

Thanks!

First of all u need to calculate ur load. Mostly its not feasible to run high energy appliances on solar, like AC, fridge, water pumps. You can have a design where u can run such appliances at day time.
The main equipments are solar panels, inverters and batteries. After determining the average load and backup time, ud get an idea of what kind of system u need. This can cost from 3000$ to 20,000$.
I would recommend using german equipments, especially inverters as the performance depends on efficiency of inverter.
I have designed solar systems and my personal advice is to not use inverter at all. A top quality inverters also waste about 30℅ of energy and it can be upto 50℅, mean half ur energy is wastes. Instead i suggest using DC home appliances. Nowadays u can easily get dc fans, fridges etc. This way u save money by not using an inverter(they are expensive), also u save alot of energy from being wasted as inversion losses.

Sir one idea might be to invest in an automated meter which allows you to transfer some of your excess power to the grid and take from the grid when your batteries are exhausted. I think KE asks for Rs 200,000 for such a meter. That should be step one, because of Karachi climate during the day your batteries will get charged very quickly and then you won't be able to charge anymore and you can use the excess to subsidize your electricity bill. Then during the night you can use the batteries till they run out and then automatically switch to the grid when they are exhausted.

Obviously if you have infinite amount of battery storage you won't need to transfer power back to the grid.

Excellent best of luck. There are lots of bona fides companies that will do it for you.
Btw in the UK any surplus power is sold back to the grid . Hence paying for it . Once the money has been recouped it's all profit
