What’s The Best Solar Panels

How Much Does A Solar Panel Cost

Prices have been coming down steadily over the years. The total cost will depend on how many kilowatts of power your array will generate. According to consumer reports, after solar tax credits are accounted for, the cost for a solar panel system on an average-sized house in the U.S. in 2021 ranges from $11,000 to $15,000.

Tiers Of Solar Panel Quality

In addition to cost, when choosing the best solar panel for your installation, its important to consider both its manufacture and what materials are used.

We consider there to be three tiers of manufacturer quality and Energy Matters only supplies solar panels from the first tier.

How Can You Slow The Degradation Of Your Solar Panels

Weve listed many of the ways that solar panels degrade above.

However, theres one large way that you can slow degradation in your solar panels, and it starts before theyre even installed.

DONT CUT CORNERS.

Too many people want to install solar panels on their residential homes, but they try to do so with low-quality products and labor.

Doing this will lead to faster degradation.

Instead, find a reputable solar installer and spend money upfront on a higher quality product.

Additionally, once youve installed your high-quality solar panels, make sure you maintain them according to the manufacturers instructions.

Although solar panels dont typically need too much care, a little bit of maintenance can go a long way!

Be sure to remove debris that may get caught in them and keep your panels clean.

The basic physics behind how solar power works is roughly the same across all competing photovoltaic panels. The chemical composition might change from one technology to another. But at their core, PV panels simply convert free sunshine into clean electricity.

This explains why some treat solar as a commodity. And in the short-term, it often is. No matter what panel type you install, youll start generating measurable carbon and utility bill savings right away.

However

Major differences emerge over the 30 to 40 years of each panels useful lifetime. And thats why its important to choose the right solar technology for each application. This selection process is largely based on local conditions like temperature, weather, and even how the modules will be used. As such, the best solar panels in Canada arent necessarily what youd use in Spain, Germany, or other major solar hotspots.

Take, for example, temperature.

We normally associate solar panels with warm sunny climates. But cold is actually an ally since PV performance is inversely proportional to temperature. This means that all other things being equal, youll generate more clean power from a solar panel at 0°C than you would from that same module at 30°C temperatures.

This is just one of many considerations.

Faqs About Rv Solar Panels

Q: How do I calculate how much energy I need?

A: Power is physics and math. To keep things basic, well use these definitions:

• Watt is electric power =
• Volt or voltage is electric potential or electric potential difference
• Ampere is electric current

In electricity, Watt doesnt need to be converted between currents, but when changing from AC to DC or the other way round, you need to convert. To convert AC Ampere to DC, you multiply by ten: 10A AC is 100A DC. To convert DC Ampere to AC, divide by ten. 100A DC is 10A AC.

Lets say you have a TV which runs at 110V AC and is rated 90W. This tell us that it draws about 0.81A AC. Converted to DC current, thats 8.1A DC.

Watching TV for one hour would consume 8.1Ah on a 100Ah battery, you could watch about 12 hours before the battery would be depleted.

If you factor in that you should not deplete your battery more than 60% and therefore only 40% of the 100Ah are available, that time gets reduced to a little less than 5 hours.

When you go over the appliances and devices, their power and how much Ampere they draw while considering how long want to use them each day, you can draw up a plan of how much power youll consume.

You should match the size of your battery bank accordingly. As an example: youll be drawing 120Ah per day and have a 400Ah battery. You solar panels can deliver 160Ah per day, depending on conditions.

As long as there is sufficient sunlight, youll be able to charge back up what you use.

What Is Solar Power For The Home

Homeowners who install photovoltaic power systems receive numerous benefits: lower electric bills, lower carbon footprints, and potentially higher home values. But these benefits typically come with significant installation and maintenance costs, and the magnitude of the gains can vary widely from one house to another. This article will help homeowners make the financial calculations required to determine the viability of solar power in their homes.

Durability / Longevity / Warranty

The durability or longevity of a solar panel warranty is important for a number of reasons it can be an indicator of the manufacturers confidence in its products. Reputable solar panels will have a performance warranty a period of 25 years. All of our key modules including REC Solar, feature this 25 year warranty period.

However, an important point to remember about warranty is that it will only be honoured for as long as the company operates. Its another reason to select a well known brand of module rather than purchase an obscure low-cost brand that may disappear overnight.

As you most likely wont buy solar panels directly from the manufacturer, selection of installer and retailer is also important. Its best to choose an installation company that is a service agent for solar panel warranty work for the manufacturer you select. This is because if you do strike a problem, the turnaround time to a resolution will be far faster.

Do You Really Save Money With Solar Panels

Even with todays technology, solar panels and their installation require a long time to recoup the cost of a large solar energy system. It can take up to 25 years. However, single solar panels that are used for RVs, boats or camping quickly pay for themselves by replacing expensive gasoline powered generators. Their steady charge helps expensive batteries last longer too.

Find The Best Angle For Your Solar Panels

The angle you orient your solar panels will determine how much sunlight focuses on the surface. Ultimately, the optimum tilt angle will boost your panels to harvest the highest amount of power.

So, what is the best angle for solar panels? The optimum tilt angle is the solar panel orientation that allows the sun rays to form a 90° angle with the panel surface. Photovoltaic cell systems harvest the highest amount of sunlight when the sun is perpendicularly over the panels. The tilting you make to achieve optimum electricity conversion is the best angle for your solar panels.

In this post, well go into the details of finding the best angle to tilt your photovoltaic systems. Our comprehensive article will examine how your roof, latitude, seasons, and time of the day affect the optimum solar orientation. Shall we?

Us Solar Panel Manufacturers

There are now very few US solar panel manufacturers.

Leading US manufacturers SolarWorld, Suniva and Silicon Energy have all gone broke,while market leader SunPower has moved most of its panel manufacturing to Malaysia,the Philippines and Mexico. Tesla has also closed their planned solar panel manufacturingplant in Buffalo, New York.

Ironically, the only well-known solar company with large-scale manufacturing inthe USA is the Chinese solar giant Jinko Solar, who have a factory in Jacksonville, Florida.

We do know of two smaller brands that still make their panels in America: Mission Solar in Texas,and Washington-based Itek Energy . However, they are smallmanufacturers and we are unsure of their current production arrangements or volumes.

Although the Trump administration attempted to boost US manufacturing of solar panels by imposingtariffs on Chinese modules in 2018-2019, American-made panels have unfortunately been unable tocompete with the low cost and high quality of Chinese and other imports.

The Characteristics Of Your Roof

Most residential systems are placed atop your home on the roof. Your roofs tilt, type, age, and amount of shading can all affect the number of solar panels you need. Generally speaking, its better to have more panels placed on the southern side of your roof, as thats where the sun shines the most in the northern hemisphere.

Keep in mind: Choosing the best solar panels company for you is significantly dependent on these variables. Be sure youre working with a knowledgeable company that encompasses all of these factors into your project.

Best Angle For Solar Panels By Latitude

The optimum tilt angle depends on your location and latitude. Latitude is the angle at which the sunrays forms with the earths surface during the equinox. The latitude reading increases as you move away from the Equator.

During Equinox, the sun is perpendicularly overhead the equator. Each of the earths hemispheres receives an equal amount of sunshine.

You should set your photovoltaic cell systems to face the Equator at that time. If youre in New Zealand, Australia, or other regions in the southern hemisphere, youd have to tilt your panels north. If youre building in Europe, Russia, America, and Canada or anywhere in the north, tilt panels south.

But, the best panel tilt angle depends on your latitude. The optimum tilt increases as you move away from the equator.

Builders in Indonesia, Kenya, Maldives, Ecuador, or Northern Brazil would not need to tilt their solar panels much. Houses in Canada will have to tilt their panels at a larger angle than those in Texas or Mexico. Similarly, buildings in England and Germany would have to tilt the panels at a higher degree than those in Turkey, Spain, or Greece.

Alaskans, Aussies, Russians, and New Zealanders slant their panels more than everyone else because they are farthest from the Equator.

In context, if the latitude in Australia is 35° the best angle to tilt your solar panels during Equinox is 35°.
