e. Load your house.

CAUTION:
Please get an electrician to separate the load intended for the inverter, so that the inverter will not be strained or damaged when the house is powered.

i. Power the inverter, use your voltmeter to check the voltage from the inverter outlet, that should be 230V.

ii. Turn the inverter OFF.

iii. Turn off all your appliances

iv. Connect the inverter outlet to your house power mains.

V. Turn ON your inverter.

vi. Power your appliances, starting with least voltage consuming appliance.

d. Connect Battery to Charge Controller

As stated above, the Charge Controller has positive (+) and negative (-) terminals for the battery, connect positive (+) from the charge controller to the positive for the battery and negative (-) from the charge controller to the negative of the battery.

Ensure that all connections are firm.

c. Connect Battery to Inverter

We all know that a battery has two terminals, positive (+) and negative (-), at the back of your inverter, you will see where 12V DC input is indicated.

Connect positive (+) of the battery to the positive of the inverter and negative (-) of the battery to the negative of the inverter.

Please the inverter should remain OFF at the point.

b. Connect your charge controller

The current we get from solar panels will not remain constant throughout the day, so many ups and downs will be there, so that we can not connect solar photo voltaic modules directly to charge our battery, it will spoil our battery over time.

So, we need a device called solar charge controller to control the current we receive from solar panels, the charge controller has inbuilt PWM (pulse width modulation) charger to charge the lead acid battery in three stages, which ensures long life for battery.

The charge controller has three connecting points for Solar Panel(s), Battery and Direct Current(DC). In this tutorial, we will use only the first two.

If you look at the back of the solar panel in the first step (a. Mount your solar panel) diagram above, you will see two wires, they are positive (+) and negative (-) respectively. Connect them to where solar panel is indicated on the charge controller, connect positive to positive, negative to negative.

a. Mount your solar panel

Here you may require some level of help from those guys who "roof" houses to enable the solar panel firmly nailed or screwed to your roof "before breeze go carry am go...lol".

To have maximum harvest of sun rays by the solar, please place it where you can have direct sunlight especially when sunlight is the most during the day.

When the solar panel is exposed to a direct sunlight, it should give you at least 26v if you use your multimeter or voltmeter to measure its voltage.

Question:

I suffer more than 12 hours power cut per day, Normal inverters could not get full charge with this severe power cuts,

I want to go for Solar inverter,

My load preference is 1 Fan, 3 CFL’s (compact fluorescent light, energy-saving light) and 1 LCD Tv.

Could you guide me on installing a Solar inverter set up at affordable cost?

Answer:

I Appreciate your interest on solar green energy. Hopefully it will be the future of power back up industry.

For a Limited budget, I could suggest you best possible and cost effective configuration.

I am 100% sure that SOLAR inverter is the only solution for growing power cut problems.

So sit back while I walk you through how to set up a small solar power for your home

Here are the materials we will need to do this set up.

a. Inverter (850VA-1KVA), 12V.......40-45k
b. One 200-250w Solar Panel.....40-60k
c. One 12V 100AH Deep Cycle Battery....30-40k (You may use two car batteries here but must be connected in parallel)
d. 12V,20A Solar Charge Controller....10-15k
e. Battery Stand, you may improvise this.

Total: Between 120k and 160k

Course Outline:
a. Mount your solar panel
b. Connect your charge controller
c. Connect Battery to Inverter
d. Connect Battery to Charge Controller
e. Load your house.

I will provide details shortly about this course.

The world of solar cells could be on the cusp of a revolution, as researchers seek to boost efficiency by harnessing the power to recycle light.

A new study, published Thursday in the journal Science, considers the properties of hybrid lead halide perovskites, a group of materials already making waves in solar cell technology, and demonstrates their ability to absorb energy from the sun, create electric charge, and then churn out some light energy of their own.

Moreover, the researchers demonstrated that such these cells can be produced cheaply, with easily synthesized materials, making the proposition much more commercially viable.

“We already knew that these materials were good at absorbing light and producing charge-carriers,” says co-author Felix Deschler of Cambridge University, UK, in a telephone interview with The Christian Science Monitor. “But now we have demonstrated that they can also recombine to produce photons again.”

Solar cells work by absorbing the light energy – photons – from the sun, converting this energy into electrical charge, and then conveying that charge to electrodes, which take the energy out into the power-hungry world.

Hybrid lead halide perovskites were already known to do this task efficiently, but what Dr. Deschler and his team have demonstrated is an ability to do more: the perovskites are actually able to emit light themselves after creating charge – and then reabsorb that light energy.

The result is a solar cell that acts like a concentrator, able to produce more energy – to boost the voltage obtained from a given amount of light – than would a cell made of materials without this recycling ability.

“Why this is now a big thing is because the current record of photo cell efficiency rests at 20-21 percent, whereas the absolute limit is 33 percent,” says Deschler. “Our results suggest a route to achieve that limit.”

The efficiency of a solar cell refers to the percentage of energy, given a certain amount of light, it can harness for use.

According to a widely accepted 1961 paper by William Shockley and Hans Queisser, theoretical thermodynamics cap solar efficiency at 33 percent. It is simply impossible to do better, they argued.

Yet the beauty of this most recent work is not only the hope of climbing closer to that theoretical ceiling, but the materials used to do so.

“You wouldn’t expect photon recycling in our materials because their fabrication is so much simpler than others,” explains Deschler. “Our materials are very cheap to make, very versatile.”

The reason for surprise, even skepticism, is founded in the way these materials are made – via solution. This affords little control over the way in which the structure forms.

If you have impurities in a crystalline structure, you are left with a “defect site”, which makes the material “messier,” in terms of light absorption. Without such impurities, you have what is known as a “sharp absorption onset,” allowing efficient and clear absorption of the light.

“So, while they are very efficient,” says Deschler, “we’re still trying to understand why and how they’re better than other materials.”

The researchers expect considerable interest from solar cell producers looking for a cheaper, more efficient way to harness the power of the sun.
