Solar Panel - Price and Features - Nigeria Technology Guide

There was a time when solar panels were prohibitively costly and just the wealthiest homeowners can manage them. That’s changed with striking price drops during the past several decades. Now’s solar panels cost 10% less than they did a year ago, a tendency that’s borne out as the 1980s, based on Oxford University Researchers.

If it comes to making the decision on what panels to purchase, it’s crucial to keep in mind the “most affordable” does not necessarily imply “cheapest.” A solar selection might be more expensive in the beginning, but far better efficacy may signify that it generates more and more compared to other panels, which makes it a brighter and also a much more “affordable” investment in the long term.

Top 25 Most Affordable Solar Panels
If it concerns the first outlay of money, which solar panels would be the most economical for homeowners? Those seeking to obtain their solar panels and running with as little effect on their bottom line as you can take a look at these high 25 affordable panels in the marketplace nowadays.

Please note: Solar panel technology changes fast and what’s very reasonably priced today may be replaced with something much cheaper tomorrow. To make sure of costs, consult the manufacturer or builder before purchasing panels, yet this chart will provide you an understanding of approximate prices from many different manufacturers and for an assortment of solar panels. This graph is based upon the pricing of solar panelshowever, buying by the pallet or by way of a builder can usually create the per-panel cost substantially more affordable.

Factors Affecting Solar Affordability
The expense of solar panels is fixed by the manufacturer based on a lot of factors like the efficacy and anticipated longevity of these panels. As you may imagine, the greater the efficiency during a very long time period, the costlier the panels will probably be.

how the panel is made matters. There are a variety of sorts of units, such as monocrystalline (single crystal), polycrystalline (multiple crystals), gallium arsenide, cadmium telluride and amorphous silicon — and that is precisely what’s available right now. Together with the ever-changing technologies of solar, it’s completely possible that more types of solar panels units will reach the market soon.

Normally, monocrystalline panels create the maximum watts per place, meaning fewer panels may be employed to make the desired amount of power, which takes up less space. This greater efficiency generally suggests that monocrystalline panels are more costly; however, other things are involved too, like guarantees, durability and much more.

In the end, keep in mind that solar panels are just 1 portion of their entire price of the machine. Though this particular page will teach homeowners how to figure panel worth and also exhibit a few points that are required to make the proper decisions regarding their solar panels, there are different sections of a system that a homeowner should think about.

Solar Expert Q&A
To be able to have a grasp on exactly what makes solar panels really affordable, we achieved to Outstanding Harvest founder Bill Johnson. His years of experience in the solar industry have contributed to valuable insights to what homeowners will need to understand when they start the hunt for solar panels which match their funding and their energy requirements.

How should a homeowner start when comparing solar panels?
The crucial components to look at when comparing solar panels would be functionality (they ought to create the energy that the evaluation leads one to expect), quality, durability and favorable guarantee stipulations. Aesthetics may play a part in a customer’s decision-making procedure.

There are yearly lists made by solar books of the best PV panel producers. These tools make it simple to learn which producers create an excellent product — and which ones to avoid.

Why are a few solar panels more economical?
As a customer, you’re making a long-term investment on your solar panels and everything you believe is a fantastic bargain on an unknown board may turn out to be a bad bargain in the long term. Additionally, due to the economies of scale linked to solar PV manufacturing, frequently the biggest, most reliable makers have a few of the cheapest cost panels available on the industry.

Would you have a look at a solar panel and inform if it is cheaply made?
Unlike a lot of products, solar panels have no moving parts, therefore it is often tough to tell by simply looking if a panel has been made. The market for solar PV is exploding worldwide and due to this there are businesses across the world and at the U.S. which are ready to cut corners to acquire market share. These flaws are often not visible to the ordinary consumer but lead to lower-than-rated electricity output, potential security problems and long-term durability issues.

What about solar panels that are used?
It’s ordinarily not a wise idea to buy used panels. PV panel technologies is moving forward in a very quick rate, with panel power amounts rising 10%(percent) or more annually. In 2009, we had been installing panels which were 205g per panel. The exact same size panel now is generating around 315 Watts. Additionally, it is very possible that the panel will not have a guarantee coverage for any problems that come up. In the end, it is going to be tough to obtain an installer prepared to work together with the utilized panel, because any issues that arise will have to be dealt with by his/her company and also the utilized panels are most likely to have more difficulties than a brand new panel.

Could a builder actually get a better deal? Just how much do builders indicate panels up, anyhow?
Normally markup on panels and other elements is 30 to 40%(percent), based upon the circumstance. This covers shipping and handling, insurance, warranty policy, licensing and a number of other costs associated with being a valid installer. PV panels are tight, awkward to deal with, delicate before being set up (do not drop one on a corner!) And must be set up in often difficult situations (just imagine carrying out a 45-pound panel up a steep rooftop at the end, then replicate that for each and every panel that has to be installed — it is not a simple work).

What many people do not understand is there is a huge amount more that goes into an excellent solar PV setup than only the panels. An excellent installation is expected to last 25 decades or longer, so every facet of the setup has to be contemplated for durability and longevity. Factors like roof angle and orientation, roof type, amount of roofing faces, neighborhood electrical utility business and local building code — that they impact the setup. There are hardly any do-it-yourselfers with the abilities required to successfully set up a system, create the energy anticipated and have it survive 25 decades. Even tiny options like the kind of roof sealant and techniques for procuring the vulnerable rooftop wiring may have a large influence on the durability of this machine. Some utility companies have quite intricate paperwork requirements simply to permit you to turn the machine on and join to the grid.

So going with the cheapest panel may actually be more expensive in the long term
It is absolutely worth the expense to employ an excellent installer that will assist you get through the procedure. Ten decades before, the panels were undoubtedly the single biggest cost at a PV installation, frequently accounting for 70 to 80 percent of their installed price of a machine. But now, panels are less than 30% of the expense of an installment. As a result of this, purchasing panels in wholesale and finding a builder to put in them will almost surely wind up costing you more than if you merely have the contractor buy straight. By way of instance, my firm, Outstanding Harvest, LLC, works together with our vendors to acquire pricing which no homeowner could get. This is due to the quantity of panels we buy, our creditworthiness and also our standing with existing customers. We hunt daily one of our vendors to make sure we’re getting the best price for the panels we all put in, and we stand behind our work 100 percent. When you’ve got an issue, we’re there to look after it.

Anything else we will need to learn about solar panel worth?
Solar panels must last and create an output of over 80 percent of their rated power for two decades. The life of solar panels varies dependent on quality of materials and also the maker. When a panel has a guarantee of less than 10 decades, you need to exercise caution. A guarantee of 25 years is quite a bit more desirable.

You ought to be able to figure out the titles of and also do research on the sorts of gear the contractor will utilize on your system. You need to learn about the new solar panels prior to getting them installed on your property. If you do not understand the title or can not locate any info about a new, you might not wish to use them or the firm — in your work.

Lifespan of a Solar Panel
Though cheaper panels may seem really good in regards to the original cost, there may be quite a hefty price to pay for moving with the lowest quote. Though all of solar panels are intended to be quite robust and resist the elements for many decades, the electricity output for a few can start to wane within the initial year of setup.

A normal solar panel guarantee should help relieve concerns; it ensures that within the course of 25 decades, the electricity output shouldn’t be less than 80% of their rated power. This helps make sure that homeowners may get constant high performance from the panels that they buy.

Panels that arrive with a lesser guarantee might end up costing more in the future — for example, a panel may show a remarkable drop in electricity during year twenty five, however when the guarantee ran out in year 10, the homeowner is out of fortune and may want to visit the cost of a replacement panel.

The Effect of Chinese Solar Panels
If you’re searching for the cheapest possible panels, homeowners may stumble upon costs which look like a fantasy come true. But, those amazingly inexpensive price tags could be connected to solar panels made with a hefty environmental and human rights impacts.

Greenhouse Gases
The production of solar panels generates greenhouse gases, therefore to be able to compensate for the influence on the environment, solar panels need to do the job for a very long time to reevaluate the carbon footprint. Cheaper panels can degrade quicker than many others, so that they may not reach the threshold necessary to compensate for their own production.

Hazardous By-products
The utilization of solar panels generates some poisonous compounds. China does not have the very same criteria for managing hazardous products since the United States does. Even though there are guidelines in place that need panel makers to recycle the waste, there’s not any word yet on if these principles are being enforced.

Conflict Materials
It’s also important to keep in mind that in some scenarios, solar panels are created with battle materials. This usually means that the employees who mine for all these minerals are under conditions of armed conflict or human rights abuses. America requires that firms disclose in which the minerals used in their products are derived from and this may help cut back on using battle materials; China, however doesn’t have such requirement. When homeowners buy solar panels which were created in China, then they may not know precisely where the stuff came out.

Shipping Outcomes
Besides these concerns, there’s also the problem of sending those solar panels round the world. Transportation creates an enormous carbon footprint, meaning solar panels need to last much longer to reevaluate the ecological costs of the dispatch. Add up all of the possible environmental effects, human rights problems and the easy question of just how long they will survive and the answer becomes apparent: Homeowners must think twice before going with all the cut-rate costs on some overseas solar panels.
