How to install a solar system right

Inverters are the brains of any solar installation. Although the inverter’s main job is to convert DC power to usable AC power, it has other functions. If there’s a problem with your system or even one panel, your inverter will definitely detect it. There are some factors you need to consider before selecting and installing your inverter. They are:

The size of the inverter.

This is one of the most important factors to consider. To know the size of inverter,you need to consider how you will use it and the power requirements. Let’s assume you have 2 fans, a fridge and television to power. Assuming a fan is 75 watts, fridge is 200 watts and television is 100 watts. Therefore, the total power requirement you need will be {(2*75) + 200 + 100} = 450 watts. With this information in mind, you can get an inverter that suits your need.

The right VA ratings.

VA ratings are the Volt Ampere rating of an inverter. The best way to determine the right VA rating is to divide the total power requirement in watts with the power factor in your home, which is usually 0.8. For example, your total power requirement is 2000 watts. The VA ratings is 2000/0.8 = 2500 VA

The type of inverter you need.

There are three types of inverters you might want to consider based on their waves. They are: pure sine wave, modified sine wave and square wave. The most recommended to use is pure sine wave. Most appliances need the pure sine wave to function well. The modified sine wave is noisier and rougher than pure sine wave and is not applicable to all equipment. The square wave, on the other hand, is the rarest of them all because they do not have much applications.

Is the inverter regulatory listed?

You need to consider whether or not the inverter is “regulatory listed”. This simply means you need to be sure the company manufacturing the inverter is one that is governed by a body, follows the rules and has a good reputation. This way, you can be rest assured that the device has met the requirements in terms of thermal tests, vibration and environmental tests.

How to connect an inverter

Most inverters are plugged directly to the battery using a thick wire. The cable size depends on the distance between the inverter and the battery. The use will be specified in the Manufacturer’s manual

The type of battery to use

A battery is an essential part of an inverter. The performance and life of an inverter depends on its battery. There are 3 classifications of batteries: Lead acid batteries, Maintenance free batteries and Tubular batteries. Maintenance free batteries are the safest to use compared to the others. They are sealed and do not require topping up or electrolyte level check like the lead acid batteries.

How long can you run appliances from the inverter?

This depends on the battery size and the type of batteries used. The inverter draws its power from the battery. The number of hours that all the appliances would run and the back up needed to run them depends on the battery capacity.

Good location

Location determines the life span of an inverter. Make sure the area has plenty of clean ventilation and is large enough. The inverter should not be exposed to bad elements like excessive heat, a wet locker, or non-sealed batteries and gas. Some specific inverters can handle harsh environments but they come at a higher cost. Either ways, it is advisable to put your inverter in well-ventilated, large areas.

So before you make your choice for the type of inverter to install, here are factors to keep your decision in check. Need more information on this, feel free to speak to us your solar expert.

4 Horrible mistake you shouldn't make when purchasing a solar system

Deciding to go solar is a big decision as it comes with the benefits of lowered electricity bill and more energy efficiency. There are many options to choose from when deciding to go solar, however, you should be careful when making a choice. Amongst the several mistakes you can possibly make, here are the most common four (4) and how to avoid them.

1. Pricing

There is nothing wrong with being cost-conscious, but watch out for prices that sounds too good to be true. Asides cost, there are other factors about quality to consider. Remember that settling for an inferior quality solar system because of lower pricing may seem like the right idea now, but the short-term savings will cost you more money in the long run when you have to replace faulty or broken system parts that failed too quickly.

2. “One size fits all” approach works

Your PV system should be perfectly tailored to you and your energy needs. When you use energy frequently, your expectations and goals should be reducing energy costs and becoming energy independent. A solar energy solution must be tailored to your future needs. If a vendor promises a “one-size-fits-all” approach or cannot explain how their system meets your needs, or worse, does not ask for this information at all, the alarm bells should sound.

3. Purchasing from unauthorized dealers

No stone should be left unturned when purchasing an inverter, be sure to buy from authorized and trusted dealers. A good dealer will ensure that you get the best products and that you always have genuine spare parts. Inability to make purchase from verified inverter companies can lead to hiccups as regards warranty policy in the event of damage due to uncontrollable circumstances within the specified period. To get the best inverter in Nigeria with warranty coverage, it is advisable to buy from the manufacturers or their Authorized agents directly where you can be given assurance. Our outlets are available around the country, bringing the best closer to you.

4. Insufficient knowledge of the product.

Learn about solar energy, learn how a solar energy system works. If you are reading this article, you can read more about how the solar system works. A world of information is available to you here on our bog.

Avoiding these mistakes will do not just the environment good, but also your pocket. Therefore, keep these tips in mind and go solar with your eyes open.

Solar power is the conversion of energy from sunlight into electricity using photovoltaics. And it is becoming common to see panels on just the rooftops only but now solar is exploring.

Renewable energy is the order of the day and every household ought to source its power from it. Renewable energy, often referred to as clean energy, comes The solar industry has come a long way over the years. The question of how solar cells and energy generation through it has become so popular is one often asked. In this article, we would be giving a brief history of the solar industry.

The invention of the solar cell set a positive change in motion for energy production. This change would iterate over hundreds of years in the hands of various physicists and engineers.

Solar energy for power for energy generation is not a new concept and has been used for centuries. Numerous experts have useddated the utilization of solar powerto as far back in history as the 7th century B.C. In its most primitive state, energy from the sun has been revered and put to use almost as long as man has walked the earth.The earliest uses of solar power included focusing the sun’s energy through a magnifying glass to start fires for cooking. By the 3rd century B.C., Greeks and Romans bounced sunlight off of “burning mirrors” to light sacred torches for religious ceremonies. The use of Sunrooms were also popular in ancient times. They were used to capture solar energy for its natural warmth. These usually south-facing rooms have captured and concentrated sunlight from the famous Roman bathhouses to Native American adobes, and are still popular today in many modern homes.

In 1839, French physicist Edmond Becquerel discovered the photovoltaic effect while experimenting with a cell made of metal electrodes in a conducting solution. He noted that the cell produced more electricity when it was exposed to light.

Later in 1873, Willoughby Smith discovered that selenium could function as a photoconductor. Just three years later, in 1876 William Grylls Adams and Richard Evans Day applied the photovoltaic principle discovered by Becquerel to selenium. They recorded that it could, in fact, generate electricity when exposed to light. In 1905, Einstein published a paper on the photoelectric effect and how light carries energy. This generated more attention and acceptance for solar power on a broader scale. The big leap toward the solar cells like the ones used in panels today came from the work of Bell Labs in 1954. Three scientists there, Daryl Chapin, Calvin Fuller, and Gerald Pearson, created a more practical solar cell using silicon.

Information about Nigeria’s solar energy technology, capacity and projects is growing. Previously, information on solar integration within the country was quite difficult to assess. Today, Solar thermal power plants are developing on the global scene with some countries investing in the technology due to it benefits.

Until recently, solar technology and scientific projects in Nigeria was mostly low-energy capacities. They included solar refrigerators, street lghtining, solar-powered water pumps and solar-powered chargers for various devices. According to a 2015 report, over 100 streets in Abuja (Nigeria federal capital city) are being powered by solar streetlighting systems. Also, there are about 58 solar projects supported by the Energy Commission of Nigeria (ECN) 50 of which target rural Electrification. Remotr communities are currently enjoying solar electrification in Zamfara, Nigeria. The Rural Electrification Agency (REA) was established in 2005 to coordinate rural electrification (maintaning and harvesting rural renewables).

With these efforts and the springing up of solar companies in the nation, the power gap which has been a major concern for Nigerians is being filled and some Nigerians are now reliant on solar power.
