8 Factors to Consider When Buying Solar Panels - SolarNRG

Consumer standards have evolved tremendously over the past few years. Unlike before, when most would settle for the cheapest product or service available, modern-day shoppers do extensive research before purchasing. While this practice may take a little more effort, it satisfies their needs and makes the most out of their hard-earned money.

If you&#;re planning to install a solar panel system in your home, the same principles should apply. As you look at different solar companies in the Philippines, there are several criteria you&#;ll need to take note of to make the best investment possible. 

What to Look for When Buying Solar Panels

To help you make the switch, our guide will discuss the things you&#;ll need to be aware of when buying solar panels.

1. Type of panel

Thanks to innovations in solar panel technology, people can power their homes with different kinds of panels. Currently, there are three types available: monocrystalline, polycrystalline, and thin film. Each has its fair share of pros and cons, and the best option will ultimately depend on your preferences.

  • Monocrystalline &#; As the oldest type available, monocrystalline panels have become the most developed. While this kind may be the most expensive, it is also known to be the most efficient. 
  • Polycrystalline &#; This type is relatively newer than monocrystalline but is continuously gaining traction amongst consumers. Its efficiency is a bit lower, but the cheaper price tag makes it an attractive investment. 
  • Thin Film &#; This type of panel is one of the latest developments in solar technology. While its power output isn&#;t as high as the other two, its lightweight build and affordable price point can give you more flexibility during installation.

2. Performance

Usually, performance is one of the first things you should look into when canvassing for panels.  You don&#;t always need to go for the most efficient option, but you definitely need a system that can seamlessly generate power. This will ensure that your solar batteries charge fast and produce enough electricity whenever you need it.

To help shortlist your options, it&#;s important to know that the average panel efficiency is around 15%&#;22%. With this in mind, panels within this range or even higher will prove to be a worthy investment. 

3. Panel size

Given that new types of solar panels are being developed and becoming commercially available, you&#;ll likely make adjustments over the years. While the roof of your house may have a lot of space, you should still consider getting the right solar panel size for you when looking for options.

As panels generate more energy per square meter, they require ample overall space. This can help you plan your whole configuration setup.

4. Roof compatibility and mounting

Since placement will be vital in harnessing solar energy and generating power, it&#;s best to see which areas of your home are getting the most sun exposure. As a rule of thumb, it&#;s best to avoid placing them in areas where they may be obstructed by trees, buildings, and other structures.  

As an important part of the whole installation, you&#;ll need to ensure that the mounting system is of good quality, especially if you live in a windy area since loose mounting brackets can cause your panels to fly off during typhoon season. Checking with your provider and asking for necessary certifications will help you avoid this dilemma.

5. Durability

Since your panels will be exposed to the elements, durability is another factor that you should take into account. Panels that easily break must be avoided since system downtime will take a huge hit on your savings. 

When negotiating with solar companies, it&#;s best to inquire about the long-term durability of their panels. Manufacturers must disclose the results of their testing to back the validity of their products.

6. Warranty

Warranty is established to protect your rights as a consumer, so it&#;s another crucial aspect to consider. In the process of gathering options, it&#;s best to partner with a provider that will give you an attractive warranty period. In case of a sudden malfunction or defect, this will help you maximize your investment.

7. Provider maintenance

Solar panels are made up of components that degrade over time, so you&#;ll need to get them serviced regularly. While cleaning and debris removal can be easily done, component checks must be serviced by a professional. 

Many companies perform yearly maintenance as part of a package deal, but if this isn&#;t specified, you should make it a point to ask and make sure it&#;s included. It&#;s also best to monitor your system religiously and keep in touch with your provider to know when the panels are due for a checkup. 

8. Provider reputation

Lastly, it&#;s best to check if a provider walks the talk. Like any other business, Solar companies can entice you with attractive ads and big promises, but it&#;s important to keep yourself grounded. To better understand a provider&#;s trustworthiness, you should look at performance reviews and experiences of past clients.  

Take the Needed Steps Toward a Greener Way of Living

Making the switch to solar can seem daunting, but don&#;t let it get the best of you. Considering the benefits they give to both the environment and your finances, there should be enough reasons for you to go for renewable energy. With this handy guide, it should be easier to take steps towards a greener way of life. 

5 Things to Know Before You Go Solar

5 Things to Know Before You Go Solar

Choosing the right solar panels for your home is like buying clothes.

Just think about it. While one coat might be cheaper to buy upfront, you&#;re likely to wear it to death within a short period of time - or, at the very least, need to spend money repairing it. 

An investment piece, on the other hand, lasts you much longer - and it&#;s likely to come guilt-free, at that. Fast fashion? No thanks!

To put it simply, there&#;s little point purchasing sub-quality solar panels that, if in need of consistent repair, replacement and upgrade, are going to defeat the sustainability-driven purpose of going solar in the first place. 

To help you decide which solar panels are best for your specific situation, lifestyle, budget and needs, we&#;ve put together the handy guide below. Having done all the hard work for you, let&#;s discover exactly what you need to keep in mind when choosing the best and most reliable solar system for your home.

At a glance, here&#;s what to look for when choosing solar panels:

  • Efficiency
  • Long warranty
  • Aesthetics and design
  • Ethical production and ESGs - Environmental, Social, and Governance-related factors
  • Ongoing customer support and guidance

Tip 1: The best solar panels are all about efficiency

Solar panels. They only operate well in the sun, right? 

Not quite. Well, not if you choose the right panel!

Many solar panel suppliers have had products on the market for over 40 years and counting. Of course, a lot can happen in 40 years. It&#;s important, therefore, that you look for signs that the best of contemporary solar technology is reflected in the supplier and products you choose. 

That way, you can be sure you&#;re choosing a reputable service that&#;s dedicated to the innovative approach needed to keep your system functioning perfectly, for longer. 

As a general guide, top-quality solar panels will usually boast qualities like premium operation in cloudy conditions as well as strong efficiency, expressed as a percentage of radiation captured vs. produced.

Solar panels are capable of processing anywhere between ~12% and ~22% of solar energy into usable energy in the home, depending on factors like panel placement, weather conditions, quality of the installation, and otherwise.

The great news is that G Store&#;s product of choice, SunPower Maxeon panels, have one of the highest efficiencies on the market. While a majority of panels fall within the 14% to 18% efficiency range, SunPower&#;s products boast an industry-leading efficiency rating - between approximately 20.1% and 22.8%.

It stands in contrast to the comparable LG panel efficiency (approximately 21/7%) and the lower Panasonic panel efficiency (approximately 20.3%).

22.8% as compared to an industry standard of around 17%? Now, that&#;s efficient!

Tip 2: The best solar panels offer a long warranty

One of the most incredible features of SunPower&#;s products is their extraordinary, industry-leading 40-year warranty - that&#;s around the same length of time that SunPower&#;s been in business!

Comparatively, LG - who have now ceased the manufacture and sale of their solar panels - offer a 25-year warranty - that&#;s still well above the industry average of 10 years for other much cheaper, less efficient products.

Of course, that&#;s not to discount the quality of an LG panel - in the last seven years, G Store has replaced only two (yes, two) LG panels total (you have a better chance of getting hit by lightning than needing a panel replaced with us!). It&#;s worth noting too that if you have an existing LG system, your warranty (and ongoing customer support from our award-winning team) still stands.

With SunPower, you can simply go one better: an industry-leading 40-year warranty that showcases the manufacturer&#;s staunch commitment to quality and unwavering faith in their product.

Tip 3: The best solar panels are designed with aesthetics in mind

Not all solar panels are created equal.

Picture this: a stunning, cutting-edge contemporary building with a minimalist design, sleek lines and&#; chunky, poorly designed-and-installed solar panels thrown on top.

No thanks. This just won&#;t do!

Of course, your home doesn&#;t need to be new or even recently designed to deserve well-designed solar panels. Older-style homes such as Victorian terraces, weatherboard homes, mid-century brick homes and more all benefit from the sleek, compact and low-profile design of a SunPower solar system due to its beautifully non-invasive appearance and installation method.

Tip 4: The best solar panels are ethical

Have you ever heard of ESGs?

Let&#;s go back to the clothing analogy for a moment. Price is one factor - but have you ever stopped to consider who&#;s making your coat, what their conditions are, and how much they get paid for doing it?

Unlike many other solar companies, SunPower staunchly aligns itself with the United Nations Sustainable Development Goals, also staying ahead of major challenges faced by the global supply chain in terms of labour and across the spectrum of Environmental, Social and Governance (ESG) activities.

Some examples of SunPower&#;s incredible activity in this area include:

  • In December , Maxeon Solar Technologies (the company that designs and sells SunPower panels) joined the United Nations Global Compact, the world&#;s largest corporate sustainability initiative 

  • Maintaining a strong commitment to humanist principles including labour rights, environmental and anti-corruptions concerns and societal goals

  • Publishing an annual Sustainability Report, prepared in accordance with the leading international sustainability standards of the Global Reporting Initiative (GRI), Accounting Standards Board (SASB), and the Singapore Exchange&#;s Sustainability Reporting Requirement (SGX). 

  • Incorporating environmental and social responsibility into the explicit design of their products, keeping the panels as clean as the energy they produce - Maxeon is, for example, the only solar manufacturer whose products have a Declare label, providing transparency in the components entering production

Tip 5: The best solar installer will offer you quality, ongoing customer support

Install solar and you join a global network of like-minded people who, just like you, care about cleaner, more sustainable, less invasive methods of powering the world.

With so many exciting incentives and other products available - from big rebates and feed-in tariffs to Virtual Power Plants (VPPs), solar hot water, solar-powered HVAC, and more - you&#;ll realise that once you go solar, the world of all-electric, net-zero living really opens up!

The obvious observation to make here is that you&#;re going to want expert guidance and support to stand alongside you during this time. At G Store, we understand that while you might have the will and passion to go solar in the first place, actually doing it can feel overwhelming and - at times - confusing.

That&#;s why our award-winning team is here to help.

With over 15+ years of experience at the helm of net-zero living in Australia, we understand what it takes to go solar, and the advice you&#;re going to need to do it safely, sustainably, and in a cost-effective way.
