Solar Panel Return On Investment
Investing in solar energy allows property owners to “lock in the cost of their energy and avoid ever-increasing utility costs,” said Tim Deters, content manager at Green Ridge Solar, a solar company based near Portland, Oregon. With the energy inflation rate at approximately 5% per year, this savings adds up even more over time, he noted.
Even homeowners who finance the purchase of their solar array will one day see a return on investment, since the cost of the solar array will eventually be paid off. For homeowners who never invest in solar power, the cost of utilities is unlikely to ever go away. Once the cost of your solar investment is paid off, you’ll enjoy free energy for your home.
How Much Energy Are You Using
If youre thinking about installing solar panels, a great place to start is with your current electricity bill. This will help you to determine your daily energy requirements.
For every 1kW of solar panels, you can generate 4kWh of electricity per day on average. So if your household is currently using 20kWh per day on the grid, as a rule of thumb, a 5kW solar system should keep things running nicely.

How Much Do Residential Solar Panels Cost For An Average 2000 Square Foot Home
Solar panel cost is often measured as the cost per watt of solar. This makes it easy to compare the relative value of solar systems of different sizes in terms of the watts of power they can produce.
Our data shows that the average cost of a residential solar system in 2021 is $2.85 per watt, before the federal tax credit. At that price, a typical 7 kilowatt home solar system would cost $19,950. The cost would fall to $14,763 after claiming the 26% solar tax credit.
The cost of residential solar panels has dropped dramatically over time. In fact, it has fallen over 70% in the past decade.
In 2019 alone, the cost of solar dropped by 5%.

Solar Energy Main Disadvantages #1 Dependence On The Weather
I think solar energy is a miracle that should not be understated. Its clean, there are no moving parts and it can help to clean up our planet.
However, solar panels have a massive disadvantage if the sun doesnt shine, no electricity is generated! This one of the biggest drawbacks of solar energy. One fundamental limitation of solar power is that the amount of power generated is hugely dependent on the strength of the suns rays.
If solar panels are shaded by passing clouds, power output will drop. This is one of the drawbacks compared to geothermal energy, for example, which is available all the time. However, solar still has significant advantages over fast disappearing non renewable resources.
Solar Panel Buying Guide Checklist
- Assess what energy you currently use and the system capacity you need .
- Check if your roof faces the right direction. Only north-facing panels will produce their full capacity.
- Make sure there are no trees, power lines or other structures shading your roof.
- Find out what local council approval is needed. Increasingly, local councils have staff on hand to help people make the best decisions on solar.
- Try to figure out your system’s payback time.
- The inverter is a key part of the system. See our guide to buying a solar inverter for all the details.
- If you’re considering adding a battery, see our guide to solar storage batteries to understand the pros and cons.
- Get multiple quotes from installers to ensure you’re getting a good deal, and make sure your installer is CEC-accredited .
- Make sure your solar panels meet the required standards .
- Check your solar panels’ product and performance warranties see below for what these are.

Solar Panel Specifications Explained
When you look at the specs for a solar panel, you’ll see a lot of numbers and terminology that you might not understand. Here are the basics.
This is the amount of power the panel should deliver under standard lab conditions . It’s measured in watts . When you see a panel described as 350W or 400W, that’s the nominal power rating.
The higher the number, the more electricity you’ll get from the panel.
Note that real world conditions on your rooftop are rarely very close to the standard lab conditions temperature, humidity and the amount of sunlight will all vary depending on the time of day, the weather and the season, and on average each panel will usually deliver less than its rated amount. But in ideal conditions , the panel should deliver at or close to its rated power.
A measure of how efficient the panel is at converting sunlight to electricity or looked at another way, it’s the panel’s electricity output compared to its surface area. The bigger the number, the better. Due to the physics and engineering of solar cells, a large amount of the sunlight energy can’t be converted directly to electricity efficiencies of about 19% to 22% are common.
That doesn’t sound like much, but it adds up even on a mildly warm sunny day of 25°C, the temperature of a black solar panel on your rooftop could be up to 50°C. In this example, x 0.37 = 9.25. So the panel has lost 9.25% of its capacity due to the heat for a 400W panel, that means it’s effectively operating at 363W.
Is It Worth Getting A Battery In 2022
The payback period for solar batteries typically sits around the 10-year mark, about the same time as the life of the battery. For many, buying a solar battery is not so much an economical decision as it is a lifestyle choice. For many, the key reason to invest in battery storage is power back-up functionality.
At this point in time, there are no indicators to suggest that battery prices are going to decrease significantly in the next 2 3 years. Therefore, it is not worth waiting for battery prices to come down before investing in solar panels.

Savings And Payback Results Differ By State
Solar power systems produce different results depending on where you live. All solar systems installed with CEC approved panels are entitled to the Australian government solar rebate. If you live in Victoria, you may be eligible for the Victorian solar rebate and be able to save up to a further $1,400 off the cost of a system, in addition to the federal rebate. The Victorian rebate can significantly reduce the payback of a system.
What Are The 2 Main Disadvantages Of Solar Energy Solar Panels Cons
What are 2/3 disadvantages of solar energy?
The 2 main disadvantages of solar energy are dependence on weather conditions and the inability to store electricity. Solar energy output depends mostly on direct sunlight. A cloudy day can reduce electricity generation by more than 80%. Solar panels generate no power at night and so batteries are needed for 24 hour supply.

How Does Solar Roofing Affect The Roofs Longevity
The durability of a roof is dependent on the material used. This concise list will give you a rough idea.
- Asphalt shingles: 15-25 years
- Clay tiles: 50-150 years
- Copper roofs: 90-150 years
How will solar panels affect the lifespan of roofs? The short answer is it extends the life of the roof considerably if installed and maintained well. A little bit of explanation is needed here.
Typically roofs are exposed to the elements day in and day out, be it harsh sunlight or heavy rains, or snow. As rooftop solar panels take on the brunt of the weather conditions and wont allow them to reach the rooftops, the roofs stay protected.
Moreover, the gap between the roof and the solar panels prevents the roofs from getting too hot. Not only can this help extend the life of roofs, but it also keeps the interior of the home cooler. The panels also prevent damage to the roof from falling tree branches and other debris.
Falling snow, hail, or ice can also damage roofs if they are exposed to them but the rooftop solar panels act as a protective shield, keeping them from harm.
To conclude and answer the question, rooftop solar panels increase the lifespan of roofs.

The Cost Of Solar Power For Homeowners
First, let’s look at the cost of installing a solar power system for your home. The average, upfront cost of a residential solar power system is between $3,500 and $16,000.
Why the huge range of costs? Well, a lot of the variation depends on the size of the system you’d like to install and the type of panels you want to use. Whatever system you use, keep in mind that solar power is capital intensive and the main cost of owning a system comes upfront when buying the equipment. The solar module will almost certainly represent the largest single component of the overall expense.
There are some additional costs, as well. Other equipment necessary for installation includes an inverter , metering equipment , and various housing components along with cables and wiring gear. Some homeowners also consider battery storage. Historically, batteries have been prohibitively expensive and unnecessary if the utility pays for excess electricity that is fed into the grid . The installation labor cost must also be factored in.
In addition to installation costs, there are some further costs associated with operating and maintaining a PV solar array. Aside from cleaning the panels regularly, inverters and batteries generally need replacement after several years of use.

Your Electricity Costs Are Already Low
According to a survey by the Pew Research Center, 96% of homeowners have installed solar, or are considering doing so, to save money on utility bills.
This makes perfect sense. Many American households spend hundreds of dollars every month on their power bills and solar panels are often the most effective way to slash that amount.
Financial modeling by SolarReviews shows 25-year bill savings in the amount of $78,682 for solar panels installed in San Francisco in 2022, for instance.
However, some homeowners dont spend very much on electricity. This could be because of one or more of the following factors:
- You have a small home
- You have a small household size
- Your home and appliances are energy efficient
- You enjoy low electric rates from your local utility
If thats you, and you pay $50 or less a month for electricity, then installing solar probably isnt worth the time and effort.
