Are Solar Panels Any Good

Whats Not To Love Good Looks Great Price Unbeatable Warranty

Are Chinese Solar Panels any good? [Solar Buying Advice 2021]

So now theres an affordable solar panel brand that offers good looks and great performance with an unbeatable 25-year product warranty. Thats great news for Australian households and businesses wanting the best value from their solar dollar!

But dont all solar panels come with a 25-year warranty?

The answer to this is YES all solar panels come with a 25-year performance warranty. But this is different from the product warranty.

How Many Solar Panels Do I Need To Power My House

When asking yourself how many solar panels you need for your home, there are again a number of variables to take into account. The most significant contributing factor here is how much energy you use. While there’s no single answer, a good rule of thumb is that it takes roughly four solar panels per kilowatts needed.

Most solar panels produce around 250W every four hours of full sunlight. So how does this all play out reality?

A 3kW PV system will be sufficient for roughly three residents, according to average energy consumption. Using this formula, a system of this size would use about 12 panels on average.

A more common size for homes in the UK is 4kW, which can provide for three to four residents. If you use the same formula, a 4kW system would need an average of 16 solar panels.

You can always use a solar PV system to power some of your home instead of all of it. That would certainly lower the number of solar panels you need, but may not be as profitable in the long run.

How Do They Work

Bifacial solar panels work just like normal solar panels. They use the same semiconductor material which generates power by converting light energy into electricity. When sunlight hits the bifacial panel, a portion of the suns light is absorbed by the solar cells and converted into electrical energy. Some of the light is caught in the glass and is reflected throughout the interior of the panel until it strikes a solar cell and gets absorbed. Some of the light passes right through the glass panel and strikes the ground. Assuming the ground has a high reflectance, this light then bounces back toward the panel and is converted into electricity.

Since they are made to capture energy on both sides, they are constructed differently. They dont have the metal gridlines that are seen on a normal panel. Instead, the solar cells are held in place by the glass structure. They also dont require a metal frame. The tempered glass helps make them more durable and weather resistant and the lack of a frame reduces corrosion and efficiency losses due to potential induced degradation, also called PID.

Solar cells in bifacial solar panels are exactly the same as in monofacial solar panels. The only real difference is that the solar cells are made to be two-sided, so the silicon p& n layers are exposed on the backside. Depending on the configuration, extra conductors may be added to the backside of the panel.

Future Of Bifacial Panels

LG Solar Panels Review

Though bifacial panels are costly, they are becoming more affordable as time goes on. Some lower-end bifacials are beginning to equalize in price with monofacial modules. The added efficiency will make them competitive as the cost per watt decreases. Bifacial modules also last longer and are more durable, making them the better choice in the long haul. Already, we are seeing increases in the market share of bifacial solar panels which directly correlate to decreases in price. In 2017, bifacial solar panels held less than 5% of the c-Si market share. In 2020, that number increased to 15%. By the end of the decade, bifacial solar panels are set to compose at least half of the market share for crystalline silicon panels.

Note: These Panels Wont Power Your Home

One of the reasons I bought this off-grid solar system was to learn a little more about how solar power works with a view to installing a permanent on-grid system in my home. Its important to note that a budget solar system like these 100 W Harbour Freight panels wont ever generate enough electricity to power your home.

12 V of power is enough to run lights, especially if you use LED lights and appliances like TVs for quite a while. What they dont do so well on are power-hungry devices like home heating and air-con systems. This isnt a drawback that this particular system its just a point to help you understand what a small off-grid solar panel system can and cant do.

However, if you want to use this as a backup system in your home during power outages, then its a simple exercise to connect several batteries, increasing your power bank. You can use a few car batteries or a more complicated system set up with more powerful electricity storage. Just bear in mind that you can expect this 100 W system to charge around one 12V battery per day.

What Rebates And Incentives Are Available

Rebates and incentives significantly reduce your cost of solar and can actually put money into your pocket each month, translating to substantial long-term savings. The best solar incentive is the investment tax credit , which allows you to deduct 26 percent of your solar installation cost from your federal taxes theres no cap on its value, but your individual tax liability will determine whether youre able to take full advantage of this incentive.

Depending on where you live, you may also qualify for other various incentives that help you save more: in addition to the ITC, local incentives like state tax credits, cash rebates, solar renewable energy certificates , and performance-based incentives can increase your solar savings up to 50 percent!

What About Net Metering

Net metering is one of the most important solar policies and incentives in the residential solar industry. Essentially, it allows you to store any excess energy produced by your solar system in the electrical grid for use at a later time. With net metering, you wont receive a monthly payment: instead, you will receive utility bill credits for the electricity produced by your solar panels. Its important to note that not all states offer net metering, so youll want to check out the Database of State Incentives for Renewables and Efficiency , which tracks net metering and other policies.

Will Installing Solar Panels Really Save Me Money

Is the HARBOR FREIGHT Solar Panel Any Good???

How long it will take for your solar panels to pay for themselves, and whether you can make money from them, will depend on the cost of your solar PV system, how much of the electricity generated you are able to use and whether you are paid for any surplus electricity.

Generally, solar panels installed on the roofs of homes and buildings wont give much financial payback for the first 20 years or so, according to Mike Childs, head of science at Friends of the Earth. But there are huge environmental benefits, depending on where you live and how much electricity you use he says. The average person contributes 12.7 tonnes of carbon per year, but by installing solar panels around 1 tonne of carbon can be saved annually, so the potential is significant.

What Types Of Solar Panel Are There

There are three main types of solar panel to choose from monocrystalline, polycrystalline and thin-film. Monocrystalline is the most common option you will see on residential homes. This is considered to be the most efficient of all the solar panels, but it comes with a steep price as a consequence.

Polycrystalline panels are a little less efficient by comparison, but they don’t cost as much. Thin-film panels, on the other hand, have a much finer design, which makes them more flexible and portable. These arent as efficient as monocrystalline though. The best option for you will depend on your home and your budget.

And then there’s the question of solar panels vs. solar shingles. Solar panels are more traditional, and are lower in cost by comparison. Solar shingles are newer, and rather than sitting on top of your roof, are designed to look like your shingles, so they’re more aesthetically pleasing. However, solar shingles are significantly more expensive than solar panels.

Risen Solar Panels: The Verdict

Risen solar panels have always been a stand-out choice for performance, durability, and quality.

Now, with the new 25-year product warranty, Risen solar panels provide a huge leap in additional value thats hard to beat.

Thats why at SolarRun we recommend Risen solar panels when performance, reliability and value are top considerations.

If You’re Likely To Move Home In The Next Decade It Probably Doesn’t Add Up

As it takes typically more than 10 years to recoup your installation costs, if you’re considering moving it’s probably not worth it .

While you could physically remove the panels from your old home and install them on the new one, this could prove costly. Plus, while you could still use what you generate yourself at your new address, you’d no longer get paid for what you export. To receive payments your panels need to be certified by the Microgeneration Certification Scheme and the organisation told us it wouldn’t certify panels that have been moved.

It’s also worth noting solar panel installations are tailored to each home to fit the roof and be positioned to maximise the level of sunlight they receive so it’s likely they wouldn’t perform as well if you installed them on a different home anyway.

Chemicals Recycling And Disposal Of Solar Panels

Are Flexible Solar Panels Any Good?  Grid Sub

Recycling and disposal of solar panels is a key area of concern. There is a clear problem with solutions on the horizon.

This is not as widespread or toxic as it may seem though. Standard solar modules’ silicon wafers are encapsulated, commonly by ethyly vinyl acetate . This layer protects the silicon wafer. If modules are not disposed of properly and exposed to specific test conditions is it possible some leaching may occur. Under normal operating conditions these materials will not be released.

Solar power is very effective at carbon mitigation. As with all technologies, the unintended waste or byproducts is something that must be dealt with.

An obvious answer is to recycle solar panels and sell their base elements. Great in theory, but this path is not an economical, scalable one yet.

Paths Forward

Large scale solar panel recycling plants do exist, but are not as prevalent as they need to be.

This lag is expected with new industries and technologies. Auto recyclers did not appear the day after the Model T rolled off the line. Bottle depots were not waiting around for the advent of bottles. E-waste recyclers have just recently become common place, decades after the explosion of consumer electronics.

It takes time for secondary industries to develop around primary industries.

Both options will take time to implement and perfect.

No fuel source is perfect, each has their own environmental advantages and disadvantages.

But some are better than others.

Genssi 100w Flexible Solar Panel

OFF-GRID LIVING – Is solar energy any good?

This is an inexpensive marine-friendly flexible solar panel for your boat or seaside lodge. Genssi 100W got my attention with the aluminum frame which has not rusted a bit so far.

On the other hand, the solar panels came in flimsy packaging and physically damaged. My guess is that connectors were not secured separately but wedged between the two solar panels in the box.

Both of them worked fine one season despite the scratches and dents and the next year, one seemed to have lost its efficiency and delivered only 10 watts.

Issues You May Encounter When Buying Cheap Flexible Solar Panels

Really cheap flexible solar panels are made in a manner that keeps costs to minimum using a mixture of various cheap low grade cells, usually seconds. Individual cells are graded for quality at the time of manufacture. Good quality solar panels only use high-grade cells, while cheaper panels use lower grade cells, or a mix of different grades cells to keep costs down. You can tell this by an inconsistency in the colour of the cells across the one panel. Cells that are seconds may have cracks, chips and damaged surfaces.

The junction boxes where the positive and negative cables connect with the panel and where the bypass diodes are fitted requires careful soldering and sealing with heat conducting sealant to prevent corrosion and to dissipate heat from the diodes. Junction boxes in cheap panels rarely have more than one diode and are usually not sealed. Moisture will quickly corrode the junction box internals when sealant is not applied.

The encapsulation layers are usually made from the cheapest materials available and may come apart, fade or warp over time.

The completed panels rarely go through quality control and testing prior to shipment.

Check Out Smaller Installers

These inflated solar prices often come from some of the larger solar installers in the industry so its important to consider all of their solar options, not just the installers large enough to pay for the most advertising. The same 2017 NREL report referenced above found that quotes from large installers were typically 10 percent higher than those from mid- and small-sized installers. If you receive quotes from some of the bigger companies in the industry, just be sure to compare them with quotes from local installers so you dont overpay for solar.
