Proper Sizing of the required battery bank has to be done to prevent unwanted wastage. The number of solar panels is dictated by the size of the battery bank which further depends on the requirement. You don't what a situation where the batteries are undercharged as this destroys them. Consider the right inverter size for your load as over-sizing results to overall system inefficiency if the load is way lower than the inverter output power. Lastly solar power is expensive both installing and running as the cost per kwh is higher as compared to mains power for the same task. Unless there is no mains electricity or you what backup go for solar. On Wed, May 28, 2014 at 10:22 AM, Collins Areba | Tel +254 707 750 788 | twitter @brainiacKE <arebacollins@gmail.com> wrote:

peter there are gadgets smart enough for your requirement. some "Outback" Inverter charger for example can take in three different power sources, and have in built logic functions to for example move up a preferred input source , so for example if you have wind, Mains and Genset opt for Wind, then mains, then Genset depending on if what is available is enough for what is needed. Similarly as Job correctly stated, you want to operate with optimum storage. Ideally discharge and recharge cycles should be in the 80th to 100th percentile. So your total power need should comprise only 20 percent of your stored energy. On Wed, May 28, 2014 at 5:44 PM, Peter Karunyu <pkarunyu@gmail.com> wrote:

@collins and job, what if one wanted to add a couple of small'ish wind power-generating-thingies, how will that fit into the equation?

And if one manages to generate more power than they are using, does it degrade any of the equipment in the setup?

Job, you answered the question I was about to ask.

For instance, if my monthly usage on electricity is KES 1,500, that translates to KES 18,000 per annum. Let's say I stay in the house 24hrs and run everything non-stop, I think I will (on the higher side) double this amount. So, the question is, is there a complete Solar set that costs around this amount (say 40000) and will let me run for the next 3 years without spending on it again?

If you look at the process of making the solar cell wafers, you will realise its not environmental friendly just the part you convert solar to electrical energy is. Until we make solar cells efficient to a level above 75% in converting energy and we have batteries that can store massive amounts of power on a small size cell renewable power is only good for off grid and backup use not as a main source of power.

At last someone reasons like me on the last bit. Was tempted to install last year but "called myself for a special economic forum meeting". Finally i realised, Solar power isn't cheap at all BUT only environmental friendly. If you breakdown the cost + maintenance + lifetime of the same, its not worth it. Just a hype.

I have done my maths and can attest to this.

@Job 75%? That is asking for too much. Even 30% is highly acceptable for solar cells. The reason solar should be encouraged is so that people have something (power) to play around with without getting a huge discouraging bill at the end of the month. Main grid(read other sources) is not going to be cheap any time soon in Kenya. apparently the most innovative thing for Kenya Power is to increase tarrifs so as to improve on the 3B profit every year. That means when we get nuclear power we will have things like Fuel Disposal Levy, Radiation Protection Levy, Cooling adjustment Levy ...et.c

I think the most expense comes on storing the power and not the panels. I think the first step is calculate all your Watts need in total (if your appliance has no watts labled multiply Amps with Volts e.g 240x2amps=480Watts) that total will also be used to know the inverter you need. To get a clean current, you will need a pure sinewave inverter which are not cheap compared to "modified sine wave" inverters I think solar power aint cheap at all. Its just convenient With Kind regards Morris.

​To answer that, answer me the following; 1.

@Collins since you're in a farm have you thought or already implemented biogas. I am thinking if you have a generator that can run on biogas isn't that a cheaper option as compared to solar? With domestic biogas usage, you don't have to incur the cost of compressing it.

@Wilson, (FYI I intend to go fully renewable here at the farm: animals and plants farm, not server farm)

Here is the logic I use. 1: The Primary ways I use power the most is Heating, and Cooling. That covers almost 70% of my energy costs. (refridgeration, cold rooms, chillers, etc etc). Space heating, AC2s , etc.

2: The second highest is in heating: Water heating.

3: The Other really heavy usage of energy is in Pumping (stationary prime mover pumping for about six or seven hours.

4: For me lighting, computers and entertainment (TV, radio etc) fall under "misc" and are less than 5% of the house.

Primary production will be solar (For purposes of this Ill use Solar because thats practical in a lot of cases.) The challenge is how to produce, and store enough energy to do what one needs to do throughout. This is where costs suddenly skyrocket.

My Theory: If I can find alternative ways of storing "Heat", and "Cold" that are cheap, easy to bulk and affordable, I can easily triple Production of power from my budget.

So far ways Im thinking of doing this are:

a) Find ways of using something like Nitrogen as a heat exchanger, storing "cold" for use when needed. This would take the form of freezing nitrogen, then releasing it to some heat exchange medium to release coolness. If I get a Nitrogen powered freezer, the better. Obviously other materials may apply better than Nitrogen.

b) Find ways of storing heat, Off the cuff Im thinking replicating a big thermos flask. Obviously sizing it up and going large. Find ways of pre-heating food , or a liquid heat exchanger system for doing even things like cooking...

c) Efficient design: Looking at structures at the farm in view of conservaton.... etc etc etc..

Thats the plan.. Whether this works enough to make it fully independent however is another story... will keep updates coming.

1. What would it cost and wattage to light up and power all home accessories(fridge, hifi and media players, tv, heaters etc ) (say a-massionette or a bungalow) with security lights. 2. ​

​The lifetime of the solar unit and its power banks and their costs. 3. What is maintenance cost of the solar power system and the "throughput" (of the same).

​In my calculations, with the cheapest kit + dry-batteries i would ​do 10-20 years to cover the ksh.200, 000 (-batteries) unit that would barely light 3-5bulbs + 1tv, 1hifi (no fridge or heaters)....

its a business/environmental case but doesn't make economical sense - again just a hype.

Installation cost is nothing, 10-20k depending on where and work to be done.​

I stand to be corrected if there are cheaper solar systems out there....

Proper Sizing of the required battery bank has to be done to prevent unwanted wastage. The number of solar panels is dictated by the size of the battery bank which further depends on the requirement.

You don't what a situation where the batteries are undercharged as this destroys them. Consider the right inverter size for your load as over-sizing results to overall system inefficiency if the load is way lower than the inverter output power.

​

=========================================================================== ​

Lastly solar power is expensive both installing and running as the cost per kwh is higher as compared to mains power for the same task. Unless there is no mains electricity or you what backup go for solar.

​At last someone reasons like me on the last bit. Was tempted to install last year but "called myself for a special economic forum meeting". Finally i realised, Solar power isn't cheap at all BUT only environmental friendly. If you breakdown the cost + maintenance + lifetime of the same, its not worth it. Just a hype. ​ I have done my maths and can attest to this.

Kind Regards, Wilson./

i find this talk interesting http://www.ted.com/talks/donald_sadoway_the_missing_link_to_renewable_energy in quote... What's the key to using alternative energy, like solar and wind? Storage -- so we can have power on tap even when the sun's not out and the wind's not blowing. In this accessible, inspiring talk, Donald Sadoway takes to the blackboard to show us the future of large-scale batteries that store renewable energy. As he says: "We need to think about the problem differently. We need to think big. We need to think cheap."

There is actually an array of options that will come on board with time, for the case of Biogas, I would like to get into it once I can consume that much power. I am also battling with small hydro which is cleaner and possibly cheaper to implement, but still dealing with wide, slow moving river with fluctuating heights...

Solar Power would be good to supplement your electricity supply. I did a little research: 2 batteries of 200Ah maintenance free = 66k 1 Xantrex 2424 inverter = 130k 1 Charge controller SUNPOWER10 12v 10amps = 5k 4 solarpanels of 30Watts each = 15k x 4 = 60k =============== Approximately 260k =============== If by day, you run your fridges and TVs run on Solar. And at night you run the appliances by electricity, your electricity bill will be quite less. Also if you live in a 'high security need' area - you will need backup electricity to keep those lights/cctv on and ring the alarms in case of anything. BR/

lol ! The math of cos would change based on your consumption per day. Of cos if your power consumption is more, of cos you will increase the charging rate, which means more solar-power Our electricity bill comes at between 3500 to 4000 per month. Personally, with such costs going to KPLC pm - combined with unexplained blackouts we see for 3 days at times - the solar offer looks more attractive everyday ..

I am thinking that the solar investment will surely save you some costs - and increase some conveniences. Yes, its a luxury, but when those blackouts occur [during World Cup Finals] , one swears by their father's garden that they will invest in solar the next day !!! In 3-5 yrs [as per guarantee of battery life] - you will invest another 60-80k in batteries [inflation factored in] In 15 years ..... 15 years too far, we will probably be running our appliances on an infinite charge helium cell :)
