What Is A Solar Energy System
Solar Energy System consists of 4 main components that decide the working of a solar energy system.
- Solar Panel
- Panel Stand, and
- Solar Panel Installation Accessories
Solar Energy Systems are of different types and can be used as per your needs and location. The 2 types of Solar Energy System are:
- Solar Panel with Battery
- Solar Panel without Battery
Note: A Solar inverter is the main component of both the systems. While we install a solar energy system, we generally buy the following products:
How Does Sunlight Amount Affect Solar Panels
Different areas of the United States receive more or less sunlight compared to other areas. The amount of sunlight you receive directly correlates with how many solar panels you will need.
Typically, southern states get more sun than northern states. But southern states with higher altitudes and less cloud coverthink of Arizona and New Mexicoget more energy from the sun than states such as Florida or Georgia. So, for the same size house, you would generally need more solar panels in Georgia than you would in Arizona.
Remember, the sun may be shining, but if it is behind a cloud, youre not getting the same amount of solar energy absorbed by your solar PV system. This means that a solar panel in San Diego will produce more energy in a year than the same exact solar panel located in Seattle.
The image below will help you determine the solar energy, known as solar insolation, in your area. Exploring your sun number score should also be helpful. If your roof does not get a good amount of sunlight and you live on a good size amount of land, you may have other options for mounting solar panels elsewhere with better sunlight.
Which Direction Should Solar Panels Face In California
It is recommended that solar panels in California be installed facing south to southwest. This gives you the most amount of sun in the day and maximizes the output from your panels. While most solar experts say that having your panels facing the south is the most effective, this may not always be possible for every home. In these cases, positioning them toward the southwest can often be just as efficient and may give you more options and flexibility for how you install your panels. Things like shade, roof slope, and overall location impact the final positioning of your panels.
How Much Do Solar Panels Cost In Australia
The reason solar panels cost different amounts in different states of Australia is that the rebate each state pays per KW produced is different. Also, panels required for solar PV to generate the same amount of electricity also vary from state to state.
Refer to the below table for specific information on the cost of installing solar PV in Australia by state.
Factors That Contribute To The Cost Of Solar Panels
There are many factors that contribute to the cost of solar panels. Understanding the how and why of any cost variance will help you plan your solar installation accordingly. Lets review the elements that impact the overall cost of your solar system and how you can use them to your advantage.
The cost of solar panels has become more and more affordable as the industry grows. In fact, government incentive programs have allowed homeowners to install solar panels at a reduced cost. However, the type of solar panel system, property location, and the size of the system are variables that greatly impact the overall solar panel cost. When you are considering going solar, you should also consider these factors to determine the right system and method of installation for you.

Factors That Affect The Cost Of Solar Panels
Before a solar professional can give you a cost estimate to install panels on your home, theyll ask you many questions about your energy usage and what you want out of a system, if your aim is to reduce energy bills and be more eco-friendly for example. Then, theyll calculate that cost based on the following factors:
- Your geographic locationSolar panels and the labor to install them cost more in different regions.
- How much power you want to offset
- The size of your roof
- Your usage patterns
- The efficiency of the home
- The cost of the equipment
- If you wish to add a storage system
- Other expenses like permits, warranties, and municipal fees.
Most homeowners install solar panels on their homes to save money on their energy bills. And according to Jamie Haenggi, executive vice president and chief operating officer of ADT Solar , ‘most consumers save on par or less of their regular energy bills.’ However, how much homeowners save varies. ‘You can have neighbors with identical systems, and they will see different levels of savings on their bills,’ says Jayson Waller, founder and CEO of pink energy . ‘Usage patterns, the efficiency of the homes, the location of the panels, amount of shading, and even how much you entertain are all contributing factors.’

What Factors Can Affect The Cost Of Solar Panels For Your Home
Electricity consumption of your home
Basically, if you use more power, you are going to need a bigger system to keep up with demand. It kind of cons with the territory with larger families. More lights, televisions, fridges, etc. The more power you need, the more your solar power system will cost.
Depending on where you live in Australia, will have an effect on the price to install your solar PV system. Different states have different rebates so this affects the overall cost of system installation. Also, the amount of sunlight you get in Tasmania will be different from that in Darwin, so the number of panels can vary to produce the same amount of power.
The quality of panels and inverter you invest in
If you dont do your research, you can end up paying twice as much for the same quality solar system all depending on the brands of the panel and inverter your installer talks you into.
Ease of installation
Some homes are a bit of a nightmare to install panels on and it simply takes longer. For example, a 2 story house with a flat roof is going to take longer than a single-story home with a pitch that requires less work. Labour costs are a factor, but not as much as the hardware itself.

What Incentives And Tax Credits Are Available
A one-time Residential Renewable Energy federal investment tax credit is available for residential solar PV systems. The credit is based on a percentage of the total solar PV system cost. If the system is placed in service before Dec. 31, 2019, a federal tax credit of 30% of the total system cost is available. After Jan. 1, 2020, the tax credit will start to decline.
Federal Investment Tax Credit
Utility Bill Rate Design
Good electricity rate design allows you to save money when you save energy. This might sound intuitive but not all provinces are same. Superior designs have low fixed monthly fees and tiered electricity rates. Inferior designs have high fixed fees and flat electricity rates.
Ontario scores near the front of the pack when it comes to these factors having time-of-use rates and fixed monthly fees of $26 .
For example, reducing your electricity bill from 1,500 to 750 kWh per month will save you 54% on your electricity bill in British Columbia, 48% in , but only 43% in Ontario!
Note that fixed monthly fees dont disappear even if you switch to solar youll pay them as long as you remain connected to the grid. But this isnt a bad thing $26/mo is a small price to pay for using the grid as your back-up energy source!
The only way to completely remove your fixed costs is to go off the grid, something most homeowners in Ontario dont do because of high battery costs.
Disconnecting from the grid also means that you wont be able to participate in your utilitys net metering program.

How Many Solar Panels Do I Need
Your energy needs determine how many panels you need, which affects the overall price of your solar system installation. To eliminate your electric bill entirely, you must generate 100% of the electricity your home needs. Most homeowners need between 25 and 35 panels to achieve complete energy independence.
Average households need867 kWh/monthin electrical power
A solar panel typically produces about one kilowatt-hour per day, so if your daily kWh usage is 30, you would need 30 solar panels to generate all of your energy needs. If you need to generate extra energy to heat a pool or run the air conditioning for most of the year, this adds to your energy costs.
To estimate the amount of energy youll need, you need to know your average kilowatt-hours . This number should be on your utility bill as kWh used. To get your monthly average, look at bills for the past year, add up the stated kWh used and divide by 12.
Next, divide your monthly kWh average by 30 to calculate your daily average. For instance, if your average monthly kWh is 900, then your average daily kWh is 30.
For a more accurate calculation, try to factor in times when there is not as much solar power available, like when its cloudy or in the evening. There are two main ways to account for this:
These additional calculations can be difficult, but they are necessary if you want the optimum solar power system for your home.

But Are Solar Panels Cost
Solar technology is constantly improving. The sharp decline in the cost of solar has been driven largely by the efficiency at which solar cells convert sunlight into clean energy. The real question to ask today is, “Are solar panels cost-effective in 2022?”
The answer is yes. As electricity prices continue to increase across the country, rooftop solar makes more sense from a financial perspective. Most people understand that by installing residential solar panels, you may reduce your monthly electricity bill by producing your own clean power right from your rooftop. But did you know that investing in solar today can protect you against future increases in electricity costs?
The most recent data, pulled from December 2021 by the Energy Information Administration shows that the price of electricity is spiking. The national average for residential electricity was 14.12 cents per kilowatt-hour , an increase of 6% compared to one month prior. Hawaii paid the highest electricity rate at 33.97 cents per kWh, followed by California , Massachusetts and Rhode Island .
How Much Do Solar Panels Cost For A 3000 Square Foot House
For a 3000 square feet house, installation of monocrystalline panels would cost between $19,000 and $42,000.
According to the Energy Information Administration , a house in the United States sizing around 3,000 square feet requires around 14,214 kWh annually, or 1,185 kWh per month. It further adds if that house has ample roof space such that there is no shading during the day, it would need between 19 and 30 premium solar panels to produce required electricity. Here, premium refers to a solar panels which has output wattage rating of about 400 watts . If we go with previous per kilowatt price , then installation cost range can be determined as follows:
19 panels * 400 kW per panel * 2.5 dollars per Watt = $19000
30 panels * 400 kW per panel * 3.5 dollars per Watt = $42000
So it can be said that installation cost of solar panels for a 3000 square feet house can range between $19,000 and $42,000. Average cost, thus, comes out to be / 2 = $30,500.

How Much Do Solar Pv Panels Cost
Solar PV panels are used to generate electricity.
The capacity of the system will determine the cost of solar PV panels. Solar PV is typically sold by the kilowatt of install capacity for domestic properties, says Steve Alldritt, technical director of energy efficiency at City Plumbing . Generally, the price, inclusive of fitting, is around £1,500 per kilowatt, so for 4kW systems homeowners can expect to be looking at a cost of around £6,000.
Historically, most homes in the UK would not exceed 4kW of capacity on the roof because the governments feed-in tariff, a scheme which paid homeowners a subsidy for the electricity they generated, paid the highest rate on systems up to this size, he explains.
However, since 2019 when the scheme ended, we have begun to see larger installations take place. Usually, solar PV systems are now anywhere between 4kW and 6kW systems as homeowners look to install additional panels to benefit from additional electricity produced for their homes. Its worth bearing in mind however that systems over 4kW require permission from their district network operator in order to connect to the local grid so always seek this permission before making an investment.
It could be a good strategy to opt for a larger system. The fitting costs tend to be roughly the same regardless of the amount of panels that need to be installed, explains Steve.
