Re: How Efficient Are Solar Electricity Power Systems? by SolnergyPower: 10:13pm On Dec 12, 2016
From experience, the so called inefficiency happens when any or a combination of the below holds.

1. Load-Battery Ratio
The battery bank comprises of your batteries and each battery has a specified backup time. Some appliances like AC, water pumping machine drains the batteries faster than TV, fridge, lighting point.

You'll certainly have a loss of backup time if the load-battery ratio isn't properly matched.

2. Inverter size
Each inverter has its own maximum specified load. While proposing an inverter, the load should be at about 50% of the size of the inverter.

3. Bad or Weak or Refurbished Battery
There are a lot of refurbished batteries in the market. If you are sold a refurbished one, you won't draw up to 40% from the battery.

One or more bad batteries in a battery bank can affect the outcome of the system.

4. Load Separation
If an inverter isn't meant to power the whole house, the load of the house should be properly separated such that the inverter carries only what is meant for it.

5. Installation
The installer should be well grounded in some basic knowledge of the products he's installing. Also he should properly calculate the load in regards to the battery bank and advise the client on the estimated time of discharge.

6. Clients abuse.
Some clients strain their batteries and inverter. You can't use an electric pressing iron in a 1.5KVA inverter, it'll damage it. Clients behave very funny and more often than not, they don't own up to the installer.

Your opinion is not true. I currently use solar in my house and it works very well. Infact, I just bought a solar refrigerator last Saturday and believe me. It''s making a whole lot of sense as I now refrigeration of food items and cold drinks. I will be buying solar Iron this week and later the deep freezer. Then, I will call Ikejaelectric to come remove their power from pole if my hse can't be metered.

I will enjoin everyone that can afford it to go for it.

Solar Refrigerator and solar Iron indeed.

how much?
15k down payment.Thereafter you recharge it 4.5k monthly. After 1500 days of unbroken recharge you stop recharging. You recharge by loading your mtn line and the amount is deducted from your airtime. Go to any mtn retail outlet for further inquiries.
Re: How Efficient Are Solar Electricity Power Systems? by SolnergyPower: 10:24pm On Dec 12, 2016
This simply means, they use Direct Current(DC) voltage. They're are rated as 12VDC, 24VDC etc.

So when you've your solar panels to charge the battery or batteries, they will then power your appliances.

See a solar fridge below... please take note of the deep cycle battery beside it.

Everyone should be careful during this festive
season,I don't usually share this kind of stories
but this happened before my eyes
Yesterday at about 3pm my Neighbour called an
aboki (shoemaker) to fix her slippers,she allowed
him stay in the compound while she went back
inside to continue with what she was doing ,while
he was fixing her slippers,he added something
inside before stitching it but unfortunately for him
the landlord was upstairs watching the aboki
without the aboki's knowledge....when he was
done he called her to come take her slippers that
he had finished stitching it,she came out of her
apartment and the aboki asked her to wear it
,immediately our landlord screamed from upstairs
"don't put your leg in that slippers.
He rushed down and demanded that the aboki
should wear the slippers first but the aboki
refused ,one thing led to other and the whole
compound was alerted including myself.
We literally had to use force for him to wear the
slippers and immediately he placed his leg my
friend guess what.......
The slippers just cut because the aboki no sew
am well

make those 3 acs, one horsepower, inverter type acs (meaning they have VF6Ds for compressor control)

don't put a regular ac on ur inverter, unless of course you have a big inverter that can handle the HUGE initial current draw from regular acs, which sometimes is up to 10 times running current.

with He in mind, ur installation would be expensive but not too bad.

Re: How Efficient Are Solar Electricity Power Systems? by SolnergyPower: 10:49pm On Dec 12, 2016
We've been powering a pumping machine for a farm and the farm house for almost 6 months now and the solar components are still very optimal.

It's 3.5KVA inverter, 2 batteries, two solar charge controllers and 8 solar panels.

Lol i just calculated it above.You will spend more money to buy it than fueling your gen
And you still have to use Gen to charge it sometimes

Re: How Efficient Are Solar Electricity Power Systems? by markpenk: 10:57pm On Dec 12, 2016
Thank you for this. But, if you're using pressing iron, won't there be a similar surge demand? I've actually seen a couple of.people using solar with just two Ac's though, so don't think that should be an issue. What do you think?
starpower:


Forget AC and water pumping there surge current and local wiring capacity might not be suItable.

1 fridge
1 tv 32-52 inches( medium backlight)
Lighting( LED LIGHTS BEST OPTION)
FAN 3PCS.

3.5KVA inverter with 4pcs 200Ah battery
Budget a million plus.
I have been using solar the smart way since 2012.
No nepa but all my clothes are in ironed.
My productivity also improved at night.

Solar system works absolutely very well. You may hear people say it dosent work effectively.
This is because the installers arent professionals. Its not just to put panels and inverters.. wrong!
Solar panels are clean energy which require complete investigation before adopting. For example, a 3bedroom apartment consumption will vary with individuals. There is no rough estimate. I cannot remember when i last bought Phcn token or fuel in my generator. I solar up already. Call me on 08077433710 for any enquiry or for installation

Re: How Efficient Are Solar Electricity Power Systems? by CoolAmbience(m): 11:15pm On Dec 12, 2016
I commend the writer for the good work.

You will agree with me that one major setback of solar systems is the fact that it drains speedily under air-conditioning load. With air conditioning accounting for between 40-60% of total energy costs by most buildings and considering the tropical climate in Africa, with its attendant hot conditions during summer periods, this becomes a big setback.

However, the performance of solar systems can be greatly enhanced by installing Solacoat zero-energy indoor cooling systems.

Solacoat effectively reflects and emits sun rays from roof-tops, thereby lowering internal temperatures by a minimum of 8 deg. Celsius and keeping indoors cooler and comfortable, without energy or air conditioning.

Kindly contact me via info@procorrsolutions.com or call +234-8039352489, should you be interested in creating comfort in your building or facility without energy and start making substantial savings.

Solar electricity is a very good clean energy.But my worries is the high cost of all the processes from procurement,installation and maintenance.Many people can not afford it...why? we are still importing the components,there are very few solar companies who can make affordable provision and thirdly we havent fully embraced the technology of solar.
Secondly we have a very weak government that doesnt look into the future.There is a solar company owned by a woman in kaduna through to out sketch of abuja.She supplies energy as pay as-you-go.She has successfully established a good business for petty traders who need light for their business.Currently she is under huge threat by some silly government policies.

In my opinion we hurriedly jumped into solar energy without counting the cost.How many research engineers do we have in solar? Do we have a place to train engineers and specialists? Do we have a sustained maintenance culture?
I know a couple of homes and businesses that use solar,trust me they are seeing hell....issues upon issues which they didnt have any slight understanding of.
Nigeria has the weather to make it work,but what about the cost?
For now we are trying to get our feet down,but if we plan towards it i think solar electricity is a huge alternative power supply that can compete with hydro and gas generation.

You're very right, Debbie.

The Nigerian govt. really needs someone to talk sense into them. Apart from the high cost of maintenance, getting high quality panels are the main issue, as our business men have flooded the market with inferior panels, for extremely high cost.

Solar panels, just like every household devices are of different grades, standards, qualities and prices. In India at the moment, you can get the best quality solar panels for cheap prices (not like super cheap) and use for like 2-years without any form of maintenance. Batteries inclusive.

Solar energy generations is a core business point at the moment; technologies like "Advancion" are taking over the renewables energy world by storm, with very minimal maintenance(s), done as per schedule/routine. You can practically use your panels/batteries for 5-years without doing jack! Our field guys only makes sure that dusts are removed from the panels surface once a week. These panels are made in India, and currently the best in the market.

The govt. of Nigeria is so naïve, that they have never even held a solar panel in their hands. In most parts of the world, all locals/citizen are encouraged to go solar, and you even have the advantages to connect to the national grid and make lots of money selling power to the govt. You use your power that's generated by you, and sell the remaining to the govt. through the grid. At the end of the month, you get paid.

Most Houses in the Middle East have solar panel. Power plants are shutting down. Solar plants are hot-cakes and its even quite easy to install/construct. A 200 MW "Advancion" solar power plant cost 400 Million Naira (design, build, and maintain) and our silly leaders are crying everywhere.

But then, what kind of regulations do they have In place that makes business difficult for the woman you talked about? Just curious.

-Continuous running costs -i'm assuming they'll need maintenance
-The practicality of using one for years and years

Re: How Efficient Are Solar Electricity Power Systems? by Emblj: 11:22pm On Dec 12, 2016
The secret of a successful solar power installation is that it has to be tailor made. There is no one size fits all like most "installers" or sellers do.

This boils down to unprofessional approach in design and installation.

Once it is professionally designed, you will definitely get the right result.

Also, the need for the user to stay within appropriate usage, i mean not overloading with "foreign" loads is a major determinant in the overall success.

I must admit that the INITIAL cost of investment in solar power is huge when you consider the shortt term, however on the long term it is highly economical.

Am available for further free consultations and advice as your deem fit.

Our problem has always been "penny wise, pound foolish."

We will rather spend small small everyday than spend heavy at once. Well, this is understandable. For those saying Solar installation is expensive....you are right. It is expensive....initially. We are talking of 500,000 and above at once.

But in the long run it is cheaper. Think of the petrol you use per day. Multiply it by 365 days....multiply it by 730 days(2 years). Just keep multiplying and see the millions you are already spending.

Mind you a single solar panel has a lifespan of 25 years. It's up to you: Spend small small all your life or spend once for once.

Call 07056578594 for more details. We install panels all over Port Harcourt.
