low cost solar panels

Today, we review the best Low Cost Solar Panels, low cost solar panels for your home and low cost solar panels for sale. There was a time when solar panels were prohibitively expensive and only the wealthiest homeowners could afford them. That has changed with dramatic price drops over the last several years. Today’s solar panels cost 10 percent less than they did last year, a trend that has borne out since the 1980s, according to Oxford University Researchers.

When it comes to making the choice on which panels to buy, it is important to remember that “most affordable” does not necessarily mean “cheapest.” A solar array might cost more at the start, but better efficiency might mean that it produces more and longer than other panels, making it a smarter and a more “affordable” investment in the long run.

Please note: Solar panel technology changes quickly and what is very affordable today might be replaced by something even more affordable tomorrow. To be certain of prices, check with the manufacturer or contractor before ordering panels, but this chart will give you an understanding of approximate costs from a variety of manufacturers and for a variety of solar panels. This chart is based on the pricing of single solar panels; however, purchasing by the pallet or through a contractor can usually make the per-panel price significantly cheaper.

Factors Affecting Solar Affordability

The cost of solar panels is set by the manufacturer based on many points such as the efficiency and expected longevity of the panels. As you might imagine, the higher the efficiency over a long period of time, the more expensive the panels will likely be.

How the panel is made matters. There are various types of units, including monocrystalline (single crystal), polycrystalline (multiple crystals), gallium arsenide, cadmium telluride, and amorphous silicon – and that’s just what is available at the moment. With the ever-changing technology of solar, it is entirely possible that more varieties of solar panels units will hit the market soon.

Typically, monocrystalline panels generate the most watts per area, which means fewer panels can be used to produce the needed amount of electricity, and that takes up less space. This higher efficiency usually means that monocrystalline panels are more expensive; however, other factors come into play as well, such as warranties, durability and more.

4 low-cost ways get solar power at home

No need for big solar panels. These inexpensive solutions give you the benefits of solar energy without a big price tag.

Did you know that the cost of installing a solar power system for all of your electricity needs can be well over $11,000? Ouch.

But wait, don’t give up on solar just yet! If making your entire home solar is out of your budget, you can still add smaller and less expensive solar elements that help save on electricity. Let’s take a look at the options.

Outdoor solar lights

There are a multitude of stationary and portable lights that can run on solar power that you can easily add to your home.

Start your solar journey in your yard. I personally have solar walkway lights by my front door and solar twinkle lights decorating my garden. The installation process for these types of lights are pretty simple — you just place the lights where you want them and make sure the solar panel is turned toward the sky. 

While lighting your yard, don’t forget about your porch light. For less than $50, you can grab a solar option like the Avaspot Solar Powered Security Light ($20), Gama Sonic Solar Outdoor Wall Lantern ($32) or the ALLOMN Outdoor Solar LED Lamp  ($20).

Device chargers

Your phones and tablets need a daily recharge, so why not make the energy source green? Solar power banks, like the Portable Solar Power Bank ($25), the Kiizon Power Bank ($40) or the Anker Solar Charger ($52), come with USB ports that you can use to charge your phone, as well as other small gadgets. The best part is that these banks are portable, so you’re never tethered to a wall outlet.

The downside is that the solar power banks charge your devices slower than a wall outlet does. Luckily the banks can recharge with sunlight during the day and store that energy to charge your devices at night — when you don’t really need them to charge quickly.

No matter which solar-powered charger you choose, look for one that can charge your devices while also recharging itself in the sunlight. Also, check to see how many items it can charge at once and if it protects your device from being overcharged.

Making your kitchen appliances solar

Don’t stop at powering your devices with solar. You can also power your small kitchen appliances — like your coffee maker, toaster, Instant Pot, slow cooker or sandwich maker — without plugging them into a wall. While the monetary savings on your electricity bill will be small, the planet will still benefit from your use of renewable energy. Plus, during blackouts you’ll still be able to cook.

All you’ll need is a 25-watt power bank you can stick in a window and a DC-to-AC inverter to make it happen. The inverter simply plugs into the power bank, so it’s very easy to set up. 

If you want an all-in-one solution, Goal Zero makes solar power kits with large storage batteries. It has everything you need to power your small appliance.

Once you have it set up, just plug your small appliance into the power bank. They’ll run just like normal. The only drawback is that that you can only power one appliance at a time, unless you have multiple power banks.

Solar water heaters

Your typical water heater uses around $440 dollars worth of electricity per year. You can save that money by going solar. There are solar water heater kits you can buy for $250 to $1,200, so they pay for themselves very quickly. 

Typically, there are three different types of solar water heaters. One thing they all tend to have in common is that they heat the water and then store it in insulated storage systems to keep the water warm until it is needed.

Batch collectors, also called integrated collector storage (ICS) systems, are the oldest types of solar water heaters and they are still popular because they need very little sunshine to heat water and they are simple to install.

You likely already know that anything painted black absorbs sunlight and gets hot quickly. Batch collectors use large black tanks or tubes to collect solar heat to warm the water inside of them. 

Flat-plate collector water heaters have a heat absorbing plate that collects heat from the sun, then transfers the heat to copper tubes. As the tubes heat up, so does the water inside them. The plates are usually installed on top of the roof to get the maximum amount of light during the day. The problem with this style of heater is it isn’t as dependable to heat water as consistently as some of the other choices. 

Evacuated tube collectors are considered the most productive solar water heaters. Glass or metal tubes full of water or heat transfer fluid are placed inside larger glass tubes, creating a vacuum. In this vacuum, very little heat is lost, so the water is heated very efficiently. Another benefit is it can even be used in outdoor temperatures as low as -40°F, according to the Environmental Protection Agency. 

Some things to look for when buying a solar water heater kit are durability and the amount of water the heater can heat up at a time. When it comes to durability, be sure that the any outside components are hail-proof, especially if you’re putting a plate on your roof. For the flow rate, look for heaters that can provide at least 2.1 gallons of hot water per minute.

TIPS FOR BUYING YOUR SOLAR POWER SYSTEM.

Buying a home solar power system can be a very exciting experience, but don’t get too carried away by advertising. Be sure to focus on the important aspects of your purchase as it’s a substantial investment and one you’ll be living with for a long time. The following are some buying solar tips on what to look for when purchasing a system.

Buying solar tips: Solar quotes online

Recommendations

Ask friends, family neighbours or colleagues who have had solar PV systems installed. Often the best buying solar tips com from right in your neighbourhood. They’ll be able to tell you about their experiences and perhaps alert you to any problems they experienced. Problems that you’ll be able to avoid. Learn more about potential issues in our consumers guide to solar power – avoiding tricks and traps.

Length of manufacturer’s warranty

Take note of what guarantees the manufacturer offers. If the manufacturer is reputable and the warranty period on the panels is substantial (at least 25 years) you would naturally expect your solar system to last long for a long time, long enough to pay for itself and make you a profit. However, for a warranty to be honoured, the manufacturer needs to be still operating. So, be cautious of brands without a track record in Australia.

Have realistic price expectations

If you are paying substantially less than many other similar size systems quoted, you may find poor quality equipment and/or poor installation work. Quality equipment and installation isn’t cheap and, like all other purchases, you often get what you pay for.

Compare components and warranty periods and check into the company providing the installation. While large, well established companies can pass on substantial savings due to increased buying power, other companies often reduce costs by cutting important corners.

Solar panel certifications

This applies to all solar panel purchases, but especially to the purchases that could attract a government rebate. The certification on solar panels indicates the type of testing that they have undergone. For instance, TUV IEC 61215 confirms that the solar panels have gone through testing by an independent laboratory and have met their advertised specifications. Other certification types are often self-assessed. Therefore, they rely on the company being honest in what it claims.

Decide on the type of panels

It used to be the case that if you had limited roof space you would need highly efficient (and very expensive) mono-crystalline solar panels. This is rapidly changing with advances in polycrystalline panel technology and some thin film technologies. Still, even if you have ample roof space you may still want to consider panel sizes vs. output. Filling up your roof with inefficient panels will affect your ability to add more panels at a later date, and does not maximise the power output of the space.

It’s also important to bear in mind that regardless of claim, no solar panel technology will produce a significant amount of power in full shade. Learn more about monocrystalline vs. thin film panels.

Solar panel mounting

Make sure that the roof, ground mounting or tracking system is engineer certified for the area you are in. For example, if you live in a cyclone prone area make sure the mounting system  and mounting brackets are also cyclone rated. Quality systems are wind certified. After all you do not want your system to take off during a wild storm . The mounting system is a very vital component and some suppliers skimp on this item. Make sure you ask about wind certification, warranty arrangements and get copies of relevant documents.

Solar inverter efficiency

A power inverter is the box between the panels and your appliances that converts DC electricity from solar panels to AC suitable for use in your home.

Not all solar inverters are equal and inverter efficiency will have a direct impact on the amount of time it takes for a system to pay for itself. Look at the inverter efficiency before purchasing a system. Obviously, the more efficient the inverter the better. Less electricity will be wasted as heat during the conversion from DC to AC. Industry leading solar inverters for grid connect systems in Australia include SMA, Sungrow and Fronius. Be cautious of  generic type brands.

Get a few solar quotes

It always wise to gather a few solar quotes when making a major purchase as you will find that prices vary widely between providers. But don’t be just swayed by price as inferior components can reduce the up-front cost of the system. However, they may wind up costing you more in the long run in terms of reliability and efficiency.

Buy solar power at discount prices

Avoid high pressure sales people

High pressure sales tactics are unfortunately common in the solar industry. Try not to make decisions on the spot, just ask the person to let you consider the offer. If it’s as good as they claim, it will still be a good deal tomorrow. Pressured decisions on the spot often turn out to be less advantageous in reflection.

High pressure sales people are only one of the pitfalls that may await you when you shop for a solar power system. Learn more about the potential issues and how to avoid them in our consumers guide to solar power – avoiding tricks and traps.

One of the best buying solar tips is to make sure to use an accredited solar power system installer, certified by the Clean Energy Council.
