Aahile yesto desh ko Situation ma - Why Nepali people are not opting for 100% Solar Solution.

I was talking with this business owner in Nepal who owns a electrical shop in Nepal, and he mentioned that - EEuta 1 family home Power Garne Solar System US $ 2500-3000 samma ma aaucha rey. He mentioned that you can completely rely on the Solar Panels and not worry about Nepal Bidhut Pradhikaran at all.

I thought to myself what a fucking genius idea. Tara if so is the case why not more homes are going 100% Solar. I mean if the claim is right you can get electricity 100% of the time and not worry about LoadShedding at all.

Of course Sabai jana le Nepal ma testo type ko solar ko laagi 4-5 lakh kharcha garna nasaklan, tara a vast majority can benefit from such type of renewable form of energy. Kinaki in fact if you think about it, aaba you can buy electrical stove and cook from it. You can buy electrical Scooter and use the same solar energy from your home to power your vehicle as well. So no need to worry about Gas Cylinder and Petrol from India. Right?

La Saathiharu, spill some thoughts and correct me if you feel I am doing too much weed.

You cannot rely on 100% on solar. The power is not enough to run for example AC or Electric heater..

No doubt, solar or wind (or some combination of solar and wind) power generated electricity can, to an extent, displace reliance on power grid provider or supplement the existing supply of power from the grid.

However, it does not completely displace the reliance on power grid provider unless you live in places in the world where the climate is very favorable for solar (or wind) power production. Hawaii is one of such an example where residents are increasingly going off grid to such an extent that residents who do use these alternative sources of electricity are seeing the rise in their power bills because the power company that provides them power have fewer and fewer costumers to spread the cost of power production and distribution.

Similarly, Denmark for example broke the world record in 2015 by producing about 42% of its entire energy needs from wind power generated electricity.

The question you are posing is a rather complex one and the claim you received about being able to get 100% of power needs off grid is bit overblown. It is true only if underlying factors for solar energy production are in place.

I have 2 solar panel for electricity in my house but it doesn't not provide adequate power like mojaboy said. Also our electric bill is almost 5000rps every month. I don't understand even after 13 hrs of load shedding. NEA is managing to make money.

To be more dependent on solar, u need bigger/efficient battery bank. I don't think its possible with 3-4 lakhs.
Check the "off-grid living" videos on utube. They have these massive battery banks.

I had been thinking about why people are not using solar power since 2 years when I saw ghampower.com.

I guess there is more to it than throwing $$ in exchange for solar panels, batteries and inverter. Based on the following link fron home depot it takes about 3ft x 10ft area to generate 480watts. And i am sure it assumes a bright sunny day with the system running in ideal condition at 100% efficiency.

Average rice cooker is about 400 watts..
Induction heaters 1 to 2000 watts(energy stored in battery during off peak time will help a bit here)..
Dont know what does fridge and other devices amount to.. Electric vehicles will probably be a few thousands of watts while charging ( unless you are willing to trickle charge and wait days for it to get fully charge). Do the maths and see how it works. See what is the rooftop area on average houses where you can get proper sunlight and see for how many hours a day will you get that light. Mind it that you loose that sunlight intensity in winter and cloudy days.

You cant go by the words of a car salesman when you buy a car.

I guess it's more important to have a good idea of how you are going to use that solar electricity ..eg using led lights, not running unnecessary appliances..riding bicycle or walking where possible instead of hopping on a vehicle..

Electric vehicles seem to be a big buzz word. But the fact is that even USA is not prepared for it. The power transmission line even in USA was not laid out with the idea of everyone charging their cars at the same time.

I heard long time ago : it is true or false.
If the electricity is not running in proper voltages, lower than usual, it tends to over speed the meter and you will be paying more every months but getting less lights/utility service.

It is possible. Power = volt x amp x cosθ for ac supply. I think our household meters monitors current flow to calculate power usage assuming constant voltage which stays constant in general. But if the voltage lowers the only way to make up for power usage is by increasing current.

If people genuinely want to help while at the same time make money then this can be a good field to invest in Nepal. I assume there are several companies already doing business in solar field. I heard about Lotus Solar company in Kathmandu like 15 or 20 years ago.
However, it seems that the ones the companies in Nepal are selling now are not in par with the new technology in terms of solar panels and battery technology. Part of the reason has to do with money (and greed, sadly). Having said that, solar products in Nepal is not cheap, and often people pay more in Nepal for older technology.
Also last time I checked, Nepali government was only offering incentive for solar products in homes outside of Kathmandu or city. I don't know if Nepali government gives VAT free on solar installations!
I mentioned about Lotus Solar company, and when you go to their website, they don't even let you see how much it costs beforehand on the web (this is one of the examples that I don't like about some of the companies in Nepal. It's like high tech flea market with price haggling everywhere and every time).

Hello Mancini, do you know how much is cost for installation and solar panel if a house already has battery inverter?

Solar power ko limitations hun6. Batti balna & few fan n led tv n 1 computer ok. But if u intend to use them for longer time ur home without electricity is gonna go black. Expensive solar powers with 2 of 200 Amps battery & 1.5 kva is gonna cost u soo much with some limitations.. its an option while loadsedding but if u wish to boycott NEA line just for that solar. U are gonna get in trouble at most needed time for sure.
Ps- back in nepal i used to work in battery n inverter related company..
