That isn't too hard to ask for; is it?

Well, great people of FTA, I think I should start this on behalf of George_D because of the request made by others who have expressed interest in alternate electricity, especially solar energy. Our FTA independence is not complete if we are to suffer frequent power outages and been dependant on the nation’s electricity grid system always. I have read in this house many times, from members “PHCN don go off, so I will track later when they come back”. No one can run away from power outages in the main electricity grid – not even the west, it happens. Hence, we all should have alternate electricity and using renewable energy is, to me, the best. This means one can enjoy their FTA fully by being totally free and not “dom” (dominated).

Look at some advantages
• Lower or no electricity bills
• Compared to generator users, there is no fuel cost and stress of getting it and no fumes.
• People living in the remote locations where power is unavailable or too expensive to hook-up too can have electricity.
Just to mention but a few.

Without going into detail, one can enjoy electricity by means of using solar energy (energy from the sun), wind mill (using energy from the wind). Don’t forget, where there is frequent electricity supply from the utility company, you can store some energy for back up.

You will need the following to complete a solar project or back up.

1. Solar panels
2. Power Inverter
3. Charge controller
4. Batteries to store energy
5. wires and cables
6. Monitors/meters

The solar panel consists of cells called photo voltaic cells and these, covert the energy received from the sun to electricity in simple terms (this electricity is a direct current
d.c). The panels can last up to 20 years plus. The panels can be fixed, adjustable or of the tracking type. You can decide to go for a complete panel from manufacturers (already made) or build panels by yourself using solar cells- the latter is for the hobbyist. The panels are rated in watts eg 80w solar panel supplying 12v continuous at a given time

The inverter
Power Inverters are available in 3 basic designs, two of which I remember very well now – the one that out sinusoidal waves and those that are modified sign wave type (meaning not pure sine waves and do have limits when it comes to its application) . The power inverter converts your storage battery power into the 240 volts AC that runs your appliances. It is the heart of your solar energy system. Unless you only run 12 volt DC appliances you will need a power inverter to supply your AC. This is just the basics.

The Charge Controller
A Charge Controller is necessary to protect the batteries from over charging and supply them with the proper amount of energy to promote long battery life.

Batteries
Without Storage Batteries to store energy you would only have power when the sun was shining. There is a lot more to batteries than just the ordinary car battery. Yo may need to change batteries over the years.

Wires and Cables
Without the right size of cables, you are likely to experience inefficient transfer of power (greater losses) and overheating.

Meters
This is required to monitor the performance of your solar system.

Firstly, it is very necessary to know what gadgets you will be using (eg.tv, sat. receiver) and how long you will use how long you would have them on the solar power and how much energy your battery can store and which solar panel (rating in power) will supply the required energy.

A lot goes into calculating the cost of setting up a solar system. First one has to consider the period of usable sunlight available at their location to do this calculation. For us here close to the equator, we get about 7 to 8 hours or more of sunlight during dry season, just a rough estimate.

How do I know I need 100w or 80w or 300 watts solar panel for my project?

The power consumption of appliances is given in Watts. To calculate the energy you will use over time, just multiply the power consumption by the hours of use.

Eg. If I have 90W tv set which I want to use for 6hrs, 25W satellite receiver for the same period, and a 50W fan for 3 hours. What will be the energy required from the solar panels for the period?

1. the energy for each appliance is Watts x time (hours) = Wh

So, the watt hours for the tv = 90 x 6 = 540 Wh (watt hours)

Watt hours for sat. receiver = 25 x 6 = 150 Wh

Watt hours for fan will be = 50 x 3 = 150 Wh

2. sum the watt hours for the individual appliances ie. 540 + 150 + 150 = 840 Wh (watt hours)

This means that the solar panel will need to supply 840 watt hours of energy to the battery each day to cover the total power required by these appliances.

3. since there are bound to be losses in the system However, to account for natural losses, we multiply the result by 1.2 (this factor allows for natural system losses, assuming 85% efficiency). Therefore, we will assume the panels will actually need to be able to supply a total of
840 x 1.2 = 1008Wh

4. so, to supply 1008Wh of energy the panel we assume to receive 7 hours of sunlight will be rated at 1008 Wh / 7 h = 144W
So, I will need 144W solar panel to supply energy to my appliances above at the given time.

Regarding point 3, it also means, if I have a solar panel rated at 100W receiving sunlight for 7 hours a day, the total energy supplied considering 85% efficiency will be 100x7x0.85= 595Wh and not 700Wh

5. Your battery should be able to store 1008Wh of energy. Since batteries capacities are rated in Ah (Ampere Hours) you need to multiply Ah by the Volt rating to know the Watt Hour. Power(W) = Voltage (V) x Current (I) ; Watt hour = VxIxHour

Therefore Ah (which is I x h) = Wh / V = 1008 / 12 (the number 12 represents a 12v battery)
= 84 Ah

So it means you will need not less than a 84Ah, 12V battery (deep-cycle batteries, not ordinary car batteries) to do the job.

NB. Another way of calculating battery capacity is explained in this example. Should my battery be rated at 84Ah, 12V the watt hour (energy) will be 84Ah x 12 V = 1008Ah

It implies that the battery can supply a 150watt appliance for 1008/70 = 14hours

Pls don’t just play around with batteries they are dangerous.

We need your contact. How can we contact you.

israelpalatoe:


A trial will surely convince you. In terms of reliablity and durability, I can only talk for my products. We are doing our best. I can assure you that the only difference between our products and the popular foreign brands is the packaging.
I also know other Nigerian producers that are doing very well.
We have all the functions of a standard and quality inverter installed in our inverters. We are improving and using our resources to learn more technologies.

We were formerly using analog design.....later we started buying digital boards from foreigners ....Now we manufacture the boards and write the codes that runs them. We are improving...... We need you ........ You can trust us!

Let us take a note from the Indians. They are one nation that have completely grown their own renewable industry based on their own experiences and in the process have become not just self sufficient but also earn forex exporting renewable energy products around the world from batteties, inverters, solar panels and controllers. Some of the biggest brands of inverters in Africa today are Indians from batteries to inverters. Rather than import and depend on likes of Trojan they built their own battery making industry with batteries that can compare with western brands in terms of durability. The likes of Luminous, Sukam, Genus, Quanta to mention a few. Sukam even partnered with Trojan to make batteries for the Indian market.
Yet all this started from humble beginning. U should go watch the story of the Sukam founder how he started the business. It wasn't from factory but from his backyard. He built learned and got better and better rest is history.

Other than the true trusted US OECD country brand of product.. Many of the products coming from China are garbage and should not come near a home. They were hand built using cheap components, crapy capacitors and dangerous engineering.. Many Chinese companies are nothing but fraudulent in their ways and will sell a pwm and mppt. The Chinese do not have the culture for standards and quality of the Japanese even Taiwanese companies are doing better.

Now am not one of the buy Nigeria blindly type.
As Oga makavele said. Do a review of your product.. Especially a tire down let us see what it is made of and get quality feedback on where to improve. The Indians built their inverters and batteries to suit their own local market and needs. Our feedback will help u shape your products for the better. While it is my hope that we build an indigenous self sufficient renewable industry exporting world wide.. Am more concern by quality of our products. We need to embrace standard not race to the bottom approach of the Chinese and also not the scam hoodwink approach of Zinox and Co who only weep sentiments

I understand all what you said but we need repeatability and reproduceability of their products as well as using factory process that ensures high quality control. The world has moved beyond backyard business for things like this

israelpalatoe:


Do you think that is how they started?
We have found ourselves at the bottom, we need to use bottom to top approach.
Are you saying we should not produce because we cant at the moment match with the production process of the developed world?
We are improving as people patronise us. We get motivations to invest more to learnings whenever we earn from our learnings.
We have drawn the map, we need your support to get there. We are building a brand, not a product only.

Goverment is not looking to invest hugly in such a sensitive area like developing our tech. Majority of us has been doing self financing.
Note: I'm not saying that you should buy out of pity or sentiment. We have grown beyond that.........Try us....!

bigrovar:
before we try you. show us your product. We are a technical bunch on here and even before we buy recommend any product (US or china) we always do our research. Do the review and tire down let see if your sword is made of Valyrian steel. try us we not cut it much here

bigrovar:


Yet many Chinese products, including many inverters we rate highly here are produced using "backyard process" only thing that guaranties "repeatability and reproduceability" is factory automation. Even in the far east it cost a lot to have fully automated factories only tier 1 solar companies can afford them. Majority of Chinese producers carry out most of their manufacturing in dingy, basements or old farm houses.. many no name black china products which floods Nigerian market are produced with little quality control yet they don't have the issue the Nigerian manufacturer have to deal with like power, lack of basic infrastructure or trained man power and a vampire government. The lad here might not have the scale to mass produce but this thing takes time. Let him show us what he has done first.

Dear NiyiOmoIyunade,

How do you ship your items from Amazon.com to Nigeria? Direct or through forwarding agents. Thanks.

4llerbuntu:
How una see this package by Forte Oil?

Comes with 2 100Amps 12V batteries.

Priced at 700k

Crazy

NiyiOmoIyunade:
When I travel I bring in stuff directly.

But mostly I make purchases from US websites and suppliers and use a Houston based courier www.sgkglobal.com to ship to Nigeria - whatever arrives at their US warehouse by Wednesday of any week will ship on Thursday and will be in your hands by Saturday of the next week.

They charge $3.95 per pound (0.454kg) of weight subject to a minimum of $20 charged per shipment - this is an all in fee and no further customs or other charge will be assessed against you.

On their web site there is a Join Now or Register With Us tab and you will be required to upload a scanned copy of your passport or other government ID to complete the registration process.

At the end of it all you will be issued a US address to use as delivery address for your goods and once your goods arrive, you can instruct them to ship to Nigeria for your pickup at their Yaba office or waybill it to your preferred location for an extra charge.

Dieumerci:


Thanks for this info.

I guessed that you pay them in, pls what is their current exchange rate.

Does it mean that the shipping cost will be rounded to $20 even if it's not up to that.?

Thanks

NiyiOmoIyunade:
Yes please. $20 is the minimum. For that price you can ship just one pin or a small box full of light electronics & equipment.

The key is to ask them to hold your packages and only consolidate and ship when the quantity makes sense for you.

Once what you are shipping exceeds 2.3kg in weight you would have crossed the $20 threshold so they bill based on the higher of actual weight or something they call volumetric weight for light packages that occupy plenty of space.

You can pay either USD to their US or naija dom account or you can pay naira to their naija account as suits you.

Hello house. Please can anyone help me with this issue. I have a Solar system setup made up of 2 panels 130w and 150w, 2 batteries of 100A each, 2 solar fans which uses DC current and light bulbs for all my bedrooms, sitting room and kitchen. The engineer run a separate connection for the system meaning I can be using both PHCN and the solar concurrently. The guy cut off Inverter. Then for me to watch TV, he said I need a converter box to convert the DC to AC. He brought the first one of 500w but could not power my 42" LG TV. He brought 1000w but still could not power my TV. Then he said I should go and buy solar TV, and I can't go for that since I will still have to power other equipment with the solar system. Any suggestions for me?
