Solar Power System

130 kw-hr/day. Depending on location, you will need about 25 to 35 Kw system. The installed costs are $7/watt, so thats $175,000 to $250,000 plus batteries, so expect to spend well over $300,000. Thats a lot of money to save $10,000 per year in energy.

Thanks alot for your reply. I'm grateful

Well don't forget the tax benefits and marketing benefits.

Here is a quote I got from a company in China to import solar panels to setup home power stations combined with 2000w wind generators to heat and cool homes. You would have to proivde which port like LA, or New Orleans and the with a shipping VIA (trucking company) to get the delivery cost to a trucking terminal in the USA.

why ship to the us when i need the equipment in nigeria

If I take enough pain pills you could be anywhere.

Hi Chike,

thanks for the information...while you give us the watthour usage you do not give peak usage times.

I have a partner in nigeria with whom I am working to do just these like projects.I am sure we could assist you with a turnkey solution as the supply install and commission is not where the job stops.

ferreiro.consulting@gmaiil.com or Atsen Ahua [atsenahua@yahoo.com]

and let us assist you first with the rest not just the start.

PEAK USAGE TIMES IS BETWEEN 8AM AND 5PM EACH DAY MONDAYS TO FRIDAYS. SATURDAYS AND SUNDAYS ARE USUALLY OFF DAYS. BUT THE DEEP FREEZER WHERE DRUGS ARE KEPT MUST BE RUNNING. BELOW IS THE PROJECTED LOAD:

1. COMPUTER DESK TOPS AND LAPTOPS 614W*8HRS=4912W

2. LIGHTS 100W*10*10HRS=10,000W

3. SATALLITE DECORDER 100W*8HRS=800W

4. TV SET 90W*2*8HRS=1400W

5. CENTRIFUGAL MACHINE 350W*2*4HRS=2800W

6. DEEP FREEZER 3000W*1*10HRS=30,000W

7. AIR CONDITIONER 6800W *1*10HRS= 68,000W

PLEASE THE CALCULATION FOR THE AIR CONDITIONER MIGHT BE CROSS CHECKED. IT IS A 2 HORSE POWER AC.

I notice you are in Nigeria. Do you have prolonged periods of heavy cloud cover during the wet?

If so you may need to oversize your panel installation or storage to allow for this, adding substantially to the overall cost.

It could be worth looking at a combined solar/wind system, depending on your site conditions.

When the sky is overcast and solar power reduced, wind is frequently strong and vice versa.

This complementary aspect could reduce the battery storage you will need.

This may give you a starting point to obtain quotes for solar panels.

www.made-in-china.com/products-search/hot-china-products/Wind_Generator.html

This is one site I found that may be useful for wind systems. You can undoubtedly google up others.

Any of the suppliers should be able to direct you to suppliers of suitable batteries, inverters etc.

Good luck

YES DURING THE RAINY SEASON WE DO HAVE PERIODS OF CLOUD COVER. THIS PROJECT IS SUPPOSED TO COMPLIMENT PUBLIC POWER SUPPLY THAT IS NOT ALWAYS RELIABLE. AS SUCH IT WILL NOT BE THE ONLY POWER SOURCE.

ANOTHER POINT, THE AIR CONDITIONING SYSTEM MY BE MY CALCULATION IS WRONG, HOE DO YOU CONVERT A 2 HORSE POWER A/C TO WATTS.

THANKS ALSO FOR SITE'S YOU PROVIDED.

Use a conversion factor of approximately 746 to convert HP to watts. Plus you may need a pump efficiency factor and a motor efficiency factor. For water systems using electric motors we usually use 0.7 and 0.85 for efficiency factors.
