all about solar panels 2021Solar Energy 101

In this chapter we’re going to break down the basics of solar energy.


Solar will be a hot topic in 2021. Don’t get burned by missing out.

You ready to dig in? Let’s start with the basics.

Solar Energy: Why It’s Important in 2021

You may have heard about solar power from a friend, an ad, or maybe you saw solar panels hanging out on your neighbor’s house.

Needless to say, the sun is a scorching hot topic right now.  In 2020 alone, solar power experienced a 37% growth in the United States.

In fact, according to SEIA, there will be 42% more solar power installed in the United States between 2021 and 2025 than the solar market installed during the last five years!

You could say that the solar energy market is… on fire. (Get it?)

There’s a simple explanation for this rapid growth.

orange-checkmarkHomeowners who switch to solar power are saving thousands in electricity costs every year by choosing to produce their own energy instead of relying on the utility companies to produce it for them.

That’s right. Even in infamous 2020 when the coal industry took a huge nose dive and renewable energy faced extreme challenges, the solar industry kept on climbing.

Don’t take our word for it. There’s evidence to back this up:

Research conducted during the COVID-19 pandemic reveals an incredible growth projection for the market over the next 18 months.

According to, the data predicts:

Global renewable energy market growth from $184.3 billion in 2020 to $226.1 billion by 2021 — with solar leading the way.

Why is this important?

The rise of employment in solar is as good an indicator as you’ll find about the trends in energy.

Old News: Fossil Fuels

Our old sources of energy are running out.

That’s right. Fossil fuels (like coal and gas), the most widely used sources of energy on Earth are non-renewable.

This chart shows how non-renewable sources like coal are starting to run out while renewable sources are just starting to take off.

Non-renewable energy, otherwise known as finite, includes any form of energy that is derived from sources that were formed in the earth billions of years ago. Which means we have to keep digging deeper and deeper into the earth to find more.

orange-checkmarkRenewable energy sources offer more flexibility to our electricity grids at a time when our grids need it most.

That goes without saying, it’s a time when energy customers need a break from electricity costs the most.

Ever-expanding electrical networks, increased demand on outdated grids, more pull of electricity required to power homes, appliances and cars — our demand for energy in the coming years is only going to intensify.

And the share of available fossil fuels will continue to decline.

It’s also a well-known fact at this point that clean renewable energies like solar and wind are better for our planet as well as the future generations who will need enough energy to power the civilizations of their own.

If we don’t curb our use of non-renewable sources soon, there will be none left for generations, not so far into the future.

what's new?
Why solar energy in 2021? It’s becoming ever more important in our current world to have
alternative sources of energy. Take a look at this:

What’s Hot: Solar Energy

All renewables are great alternatives. But you know which one rules them all?

sun iconIf you guessed the sun, you’re dead on!

The sun is the ultimate source of all other energy sources.

Think about it: everything needs the sun for power.

The sun is nature’s power plant, and it’s available to all living things on our planet.

The International Energy Agency reported in January of 2020 that solar energy is now “the cheapest electricity in history.

It’s not so hard to believe given the fact that the energy comes from the sun which is always available, every day on Earth.

solar fun fact
The amount of power from the sun that strikes the Earth in one hour is more than the entire world consumes in an entire year!

Alright, got the basics down?

Let’s move onto how we harvest the sun for power.

solar panels 2021 and the gridParts of a Solar Energy System

In this chapter we’re going to break down the parts of a solar energy system.


Let’s get started.

Understanding the components of a solar system is like knowing all about the latest technology when buying a computer.
If you have no interest, skip over this part, but don’t miss the pro tips at the end of the section.

For those curious tech hounds, let’s dig in.

1. Solar Panels

Solar panels are the part that everyone knows about. They’re the technology that’s gathering the energy of the sun from your rooftop.

There are 3 types of solar panels.

types of solar panels

Here’s the nuts and bolts.

orange bullet point Monocrystalline is the most widely used type of panel for residential use.

orange bullet point Polycrystalline panels are typically less efficient than monocrystalline and are often used for commercial buildings.

orange bullet point Thin film is more flexible, has a shorter life-span and is typically used in small solar installations.

pro tip header
You may want to cut costs by choosing a cheaper brand of solar panels, but consider the efficiency of
the solar panels you’re purchasing. Even 3% more efficiency can mean larger power output and a
better return on your investment.

Read more about solar panel efficiency.

solar panel tips
Choose solar panels that have a warranty longer than the life of your loan if you’re financing.

Hint: we prefer LG panels which are backed by industry leading warranties.

2. Microinverters

What the heck is a microinverter?

We’re here to make it all easy for you so simply stated:

Your solar panels produce DC energy. Your home needs AC electricity.

So, just the opposite of the rock band AC/DC, the microinverter is the component that turns DC your solar panels produce into 230V AC  electricity that your home uses.

Before micro inverters were invented, string inverters were the norm. Each panel fed straight into one
main inverter via “strings” attached to each panel. The problem with this was that the system would
only produce as much electricity as its least productive panel.

String Inverter vs Micro Inverter

solar panel tip
The microinverter is the component most likely to fail within 10-15 years. Choose wisely.

Hint: We prefer and only use Enphase microinverters.

3. Racking

Racking is the most straight-forward component of them all.

The racking component is what the solar panels are installed on. The racking goes on your roof, the solar panels fit into the racking. It’s as simple as that.

You generally don’t need to worry about this part, this will come with the solar installation and your solar company will handle this.

pro tip header
The most important part of this section is to understand how important it is to consider the brands
you’re purchasing. Solar is a major investment: an upgrade to your home that can last over 25 years if
you shop wisely and ask the right questions.

solar panels 2021: chapter 3
All About Energy

is solar energy worth it logo

In this chapter you’re going to learn all about home energy.


  • Understanding the electrical grid
  • What being ‘on the grid’ and ‘off the grid’ really means
  • What net metering is and how it can save you money
  • Why your home energy use is important to know and how to calculate it
  • How you can free yourself from your electric company

You ready to dive into the grid?

On your mark, get set, go!

What is the Grid Anyways?

Anytime you start talking about electricity costs, outages, blackouts and rising prices, it all points back to the grid.

Going ‘off the grid’ is something you may have heard of before.

But what about being ‘on the grid’.

Do you know what each statement means?

Do you know the difference between the two?

To sum it up easily, your home is connected to an electrical grid that’s powered by your utility company and runs throughout neighborhoods, shopping malls, office parks and across property lines.

There’s even an urban myth about better electricity reliability and higher rates when sharing a grid with a hospital. Did we mention that it’s a myth?

When it comes to your home being powered by solar energy, being connected to the grid certainly has its advantages.

For one, if your solar panels collect more energy than your house needs (which is likely depending on the day and the amount of uninterrupted sunshine), then you have the option to “sell” it back to your utility company.

This is called net-metering, and it’s available in most states.

Net Metering 2021

As of 2021, these are the states that offer unlimited, state-mandated net metering:

net metering map
Image source: Solar Power World

But just because your state doesn’t have a full-fledged net metering program doesn’t mean there are no options for your grid-connected excess energy. More than a dozen other states offer some form of compensation in exchange for your panel-produced power.

Have no fear, your solar specialist will help you take advantage of net metering or similar programs in your state.

solar tips
The solar energy you produce is way more valuable when you keep than when you sell it back to your utility company.

In fact 2-3X more valuable! So, try to keep what you can of it.

Why Home Electricity Usage Habits are Important

Year after year, electricity prices get higher. This much we know is true. But solar energy presents you with a sensible, simple option that puts you in control of your electricity usage and costs.

With that being said, are you aware of how much energy you use in a day?

If not, you might want to start understanding your energy consumption habits.

For example, take a look at the wattages for common household appliances:

Coffee Maker
900-1200 watts
750-1100 watts
800-1400 watts
350-500 watts
1800-5000 watts
100-800 watts
Ceiling Fan
65-175 watts
Space Heater (40gal)
4500-5500 watts
Hair Dryer
1200-1875 watts
50 watts
Computer Monitor
150 watts
Computer Tower
120 watts
Television 19”-36”
65-133 watts
Television 53”-61”
170 watts
1200-2400 watts

solar tips
To get a better idea of your home energy use, try using this calculation for single appliance. While the final
cost of a single appliance for the month might be less than $3, the other appliances add up. And your
usage can increase or decrease depending on your circumstances each month.

1. Calculate Watt-hours Per Day
Device Wattage (watts) x Hours Used Per Day = Watt-hours (Wh) per Day
Example: A 150-watt computer monitor used four hours per day
150 watts x 4 hours = 600 Wh/DayInstead of watt-hours. your energy bill is measured in kilowatt-hours (kWh). Since one kilowatt is equal to 1000 watts, divide the watt-hours by 1000.

2. Convert Watt-Hours to Kilowatts
Device Usage (Wh) / 1000 (Wh/kWh) = Device Usage in kWh
Example: A computer monitor using 600 Wh of electricity per day
600 / 1000 = 0.6 kWhNow, we estimate usage over a month or, for the sake of a simulated average, 30 days.

3. Find Your Monthly Usage
Daily Usage (kWh) x 30 (Days) = Approximate Monthly Usage (kWh/Month)
Example: A computer monitor using 0.6 kWh of electricity per day
0.6 kWh x 30 Days = 18 kWh/Month

4. Calculate Your Monthly Cost
Monthly Usage (kWh) x Electric Rate ($/kWh) = Approximate Cost per Month
Note: The average residential electric rate for Americans in 2020 was 13.26 cents/kWh

what's new header
Climate change is requiring more power for heating and cooling. More electric cars are hitting the road.
Meanwhile, the demand for residential electricity is increasing as more people continue working from home.

The already fragile electric grid faces even more strain in the future.

It should come as no surprise that electricity costs are expected to rise dramatically.

In fact, residential electricity costs are projected to rise between 1.2% and 2.8% in 2021; continuing a decade-long streak in climbing prices for electricity.

rising cost of electricity over the years

Why Solar -and Solar Panels Are Worth It

Electric prices keep climbing every year while the cost of solar is lower than ever before. If solar seems expensive think about it this way.

You’ll be paying your electric company for the rest of your life, at the mercy of whatever the utility company charges. Which will continue to increase due to lack of available energy resources.

It’s as certain as death and paying taxes except, unlike taxes (and death), the bill climbs higher every year whether you make more money or not.

US electricity prices graph
Image via US Energy Information Agency

Take a look at the price hike each year. (Were you paying attention?)

But What About My Solar Loan?

Some homeowners pay off their solar loan in as little as 8 years with the right incentives in place, and nearly every day thereafter, they’ll produce free clean energy from their own home.

Of course the size of your home solar system, the amount of panels, any added battery storage and your state’s solar incentives all factor into the costs, but the important part is that you are in control.

Maybe the coolest part about going solar: there is an end date for payments.

The electric company can’t say the same about their traditional residential electricity bills.

solar smart tip
If you think about it that way, the electric company made you buy something you never signed up for.
You can change that and put the power back in your hands.

What is a Solar Battery and Do I Need It?
solar battery backup

In this chapter we’re going to go through the ins-and-outs of solar batteries.


  • What is a solar battery backup
  • How it works
  • Why to consider a solar battery backup
  • How to protect your home from outages
  • Top benefits of a solar battery
  • Why the Tesla Powerwall 2 is all the rage

Ready to see what the fuss is all about?

What is a Solar Battery?

A solar battery works like any other battery except for two distinct differences:

  • It’s connected to your solar system
  • It stores solar energy

How Does a Solar Battery Work? 

To understand what advantages of having solar battery, let’s first understand how having a solar battery works into your solar panel system.

  • Solar begins powering your home in the morning when the sun rises.
  • Excess solar energy charges your solar battery.
  • Your solar battery runs your home at night.

Here is how the Tesla Powerwall, one of the industry’s leading solar batteries, works.

Read: Is the Tesla Powerwall Worth It?

Do I Really Need a Solar Battery?

Considering a solar battery can be a big decision.

On the one hand, it adds to the price tag of your initial solar investment, on the other hand it’s a really great investment for your home protection.

Let’s break down the reasons when you would need a solar battery to give your solar panels (and home) a power up!

There are 4 main reasons you’ll need a solar battery.
  • Power during the night and on cloudy days
  • Free yourself of the grid and rising costs
  • Complete control of your home energy usage
  • Protect your home and family and give you peace of mind
Power through the night.

The first major benefit of a solar battery is freedom from your utility company. That means whatever solar energy your panels produce can be stored instead of sent back to the grid. Remember how we said the electricity you produce is 2-3 times more valuable? Well, now you can keep it all!

Avoid surging electric prices.

Because you have freedom from the utility company, you won’t be trapped by the rising rates each year. The cost of energy is constantly rising due to energy resources running out, so this will become an ever increasing issue. 

average retail price of electricity

Monitor your energy.

Wondering how much electricity you use during the day and how much your solar panels produce? Having a solar battery system with the most up-to-date technology like the Tesla Powerwall can help you keep your power in your control. Using the Tesla app, you can monitor your home energy system in real time.

tesla powerwall app

Protect your home.

Do you live in an area where natural disasters are likely to occur? This is when having a solar battery really sets you apart from the rest of your block. A solar battery can keep your home powered when the rest of your block loses power, even under normal situations like routine outages.

Other important reasons to consider.

Homes that operate essential equipment that cannot have interruption like medical equipment, homes with small children, or even homes in extreme climates that need heat and AC to keep occupants comfortable.

solar panel tips
If you want to go off-the-grid completely, or as off-the-grid as possible while still having the benefits
of being on-the-grid (net-metering), you are going to need a solar battery!

pro tip header
A solar battery is covered under the federal tax credit, as well as many other statewide solar rebates
and state incentives.

What You Need to Know Before Solar Panel Installationsolar panels 2021

Now it’s time to give you all the tools you’ll need to make an informed decision about going solar in 2021. Specifically, our pro tips for staying an informed consumer with all the confusing information out there.


  • How to choose the right solar company
  • Why warranties make a difference
  • How to avoid solar scams
  • How to choose the right amount of solar panels
  • Why 2021 is the last year to save on going solar

Let’s get to it.

Where to Start

Solar power for your home is now more available than ever before, which means your decision to switch comes with many more considerations. That includes one very important question: where do you start?

If you’re convinced that solar is the way to go, it’s natural to feel puzzled about what to do next.

Let’s start with making the big decision. It can be the most dreaded step, yet, the most important part of the process.

How Do I Choose the Right Solar Company?

There are so many companies to choose from, so many different products and, like any purchase, there are even scams to be on the lookout for.

Before a single panel is placed on your roof, you’ll want to be prepared. When you know what to expect from the technology and the install team behind it, the switch to solar is a painless one.

In our experience, it’s a pretty exciting one; especially when our customers are able to finally seize control of their energy.

But don’t worry if you feel overwhelmed. We’re here to help!

Let’s just breathe and break it down together with our unique pro tips.

solar tips
Pro Tip #1: Find the Warranties

Sunpro Solar 25 Year WarrantyBuying a solar PV system is a huge investment for your home and should be treated like one. Your car has insurance, so why not have peace of mind when purchasing a solar system?

The solar panels on your roof will produce power on a daily basis, but it’s important to make sure that they last longer than the time it takes you to pay for them. A warranty is a crucial sign to determine the lifetime of the panels as well as the efficiency over time.

After making the decision to switch to solar power, this is possibly the most important thing to look out for when choosing solar products and a company that will provide and install them.

Once installed, a solar panel system is as much a part of your home as the roof on which it’s installed — even more reason to be picky when it comes to quality.

solar tips
Make sure you ask the specialist from your solar company to provide complete information about
the panels themselves as well as any guarantees of service and maintenance should any extreme or
unexpected damage occur.

solar pro tip
Pro Tip #2: Be on the lookout for scams

solar panel scamsYou might have heard a lot about solar scams. There are a lot out there, which is why it pays to choose a trusted name company.When you provide solar service to thousands of customers in multiple towns, cities and states across America, reputation matters. More often than not, the level of trust in a company factors substantially into a customer’s decision to go solar in the first place.When you’re in our position, you simply can’t afford to overlook trust. The same is true if we were in yours.

So how can you avoid a solar scam?
  • Check reviews. Any company that has mostly bad reviews, is a company you want to stay clear of.
  • Talk to your neighbors. If you know anyone who made the decision to go solar, listen to their experience. Use it to help you ask the right questions.
  • Choose warranties. As we already mentioned, choose a company that backs their products and installs 100%. This is key to protecting your investment.
  • Be aware of anything that sounds like, well, B.S. Stay away from any company quoting things like 100% consumption or something that’s too good to be true.

solar pro tip
Pro Tip #3: Maximize the amount of solar panels during install

One of the biggest regrets homeowners have after their install is that they wish they would have installed more solar panels when they had the chance.They see the amount of power produced, and they want even more — especially if it means they can connect to a home battery like the Tesla Powerwall to store excess power or sell it by way of net metering.

If you decide at some point after your install that you want more panels, it will be complicated and expensive, while adding additional solar panels to the original quote can be surprisingly cheap. Even though it may be increased initial installation costs, it’s a smart thing to consider.

solar panel iconHow Many Solar Panels Do I Need?

If you want to lower your monthly electricity bill, the amount of solar panels will be determined by exactly how much you want to lower it. If you just want half your electricity use to be reduced, your solar panel system will probably be smaller.

And if you’re looking to cover all your electric needs, you’ll probably need a larger solar panel system, which means of course, more solar panels.

Read: How Many Solar Panels Do I Need?

However, if you have limited roof space you could instead use higher efficiency solar panels. This would mean fewer solar panels, but greater generation rates.

At the end of the day, the size of your solar panel system depends entirely on your panels are worth it: what's new
As of 2020, the least amount of panels you should get (depending on your roof size) is around 22
panels. Make sure to check with a professional to find the exact amount your home will need for
maximum benefits and follow their recommended guideline.

You may also want to consider investing in a solar energy battery, which will store any excess energy your panels will produce. This will allow your home to run on renewable energy even at night.

So you went solar. Congratulations and welcome to the clean energy club! Thanks for helping make the future world a better place. Now here are a few important things you need to know.

In this chapter we’re going to go over everything you need to know about owning solar (for those of you who are curious what it’s like to actually have a system).


  • What type of maintenance solar panels need
  • How much solar can increase the value of your home
  • How to monitor your home energy use

Starting in 3, 2, 1….

Solar Panel Maintenance

The good news: Solar maintenance is a breeze.

Solar panels are built to withstand weather. And if your panels were mounted tilted, then the rain already cleans them off for you.

You may also hose them down or use a leaf blower if it’s been dry weather to keep them running at their highest possible efficiency.

If you live in snowy climates, you may need to wipe them off with a long squeegee or lukewarm water.

solar panels are worth it: fun fact
Solar panels have NO moving parts!

No moving parts means less labor and less maintenance costs.

Other than that, you can pretty much not worry about them. Especially if you have a warranty and they’re covered by your homeowner’s insurance.

Are solar panels toxic?

There are a bunch of rumors out there about solar that just aren’t true. This is one of them.

Solar panels on your home are not toxic. They will not leak and they will not do damage to you or your home.

In fact, they are the only form of electricity generation that has no moving parts.

Solar panels are made from silicon, metal, and glass which takes the sun’s energy and creates a reaction to create photons (light energy particles) which then sends it to be converted to electricity for your home. That’s it.

But what about the pollution they cause after their lifespan is over? 

The good thing is that solar panels are built to last for 25 years or more. In fact, we’re so confident about that, we have a 25 year guarantee.

When your solar panels are finally done working, you will be able to recycle them. This is because solar panels are made from silicon, metal, and glass, and all of these materials are useful for other things. In fact, they can be processed to re-use with around 80-100% recycling efficiency!

There is a lot of research already out there about recycling solar panels. Read about it.

While that doesn’t erase the damage of the trash, check this out.

After 25 years a 6.6kw system will have a net saving of around 243 tons of CO2 from the air!

You can’t argue with reducing your carbon footprint by that much.

solar panels are worth it: how solar saves co2

Are solar panels bad for the environment?

Nope. (See above)

What are solar panels made of?

Simply stated, solar panels are made of a few key ingredients: silicon, metal, and glass.

Nothing toxic, no moving parts, nothing to worry about, just clean energy converted from sunlight.

Do solar panels work when it’s raining?

Solar panels will absorb some sunshine, depending on how much sun is coming through the clouds.

On cloudy days, solar panels will generate around 10 – 25% of their normal power output.

Although solar panels do not work as well in rainy or cloudy weather, they do still work and depending on your particular situation, that may be just enough.

In fact, some of the cloudiest cities house some of the country’s best solar producers. So don’t let that deter you from installing solar panels on your home. Talk to a professional about it.

Do solar panels charge in cloudy weather?

They do! It’s the same as when it’s raining. See above for more information.

Do solar panels degrade?

Generally no. However we can’t speak to all solar panels.

This is precisely why it’s important to research the panels and the company you’re buying from. We only use LG solar panels because we believe in them and know we can depend on them.

And it makes a difference when our homeowners can trust in a brand.

Do solar panels give off radiation?

Unless you’re talking about solar radiation (which is just sunshine), then absolutely no.

Other forms of fossil fuel energy do which is why switching to clean energy is more and more important.

Do solar panels work at night?

Solar panels do not work at night because they are powered by the sun.

No sun, no power. Unless of course, you have the Tesla Powerwall which will store your solar energy from the sun and power you through the night.

What do solar panels do?

This is complicated, but at the most basic level, solar panels take sunlight and convert it to electricity to power your home. It’s not magic. Just years of developed science and product testing.

Are solar panels expensive?

This depends on a lot of things.

Read: The Cost of Solar Panels.

The price of solar panels can seem high at first. Until you start breaking down the cost with a trained solar professional. They can help you chew on some facts and math to show you what makes sense for you.

And with things like solar leases and power purchase agreements (PPAs), switching to solar can be more doable than you think.

Let’s put it this way. You’ll be paying your electric company (however much you pay them) dollars a month for the next 25 years. It’s also going up every year.

rising cost of electricity over the years

And unless you have a fixed rate, (no one?) you’ll be vulnerable to rising costs, especially as fossil fuels become less available. Because, don’t forget, they’re running out.

But when you go solar, even if you finance them, you’ll have a fixed rate each month that you’re paying. No surprises, and with things like net-metering, federal and state incentives, solar tax credits and rebates, you may end up making money in the long run.

Just let us help you crunch the numbers and find out.
