Connecting To The Grid
Most solar kits are designed for off-grid systems, which wouldn’t demand as much energy as the average home, such as tiny houses or sheds. A typical off-grid PV system costs about $2.50 per watt.
Grid-tied packages range from $2.00 to $3.50 per watt. The grid can be very useful, providing electricity at night or in times of low sunlight. Being connected requires more components, such as meters and safety equipment. You will need to consult your local utility company about regulations and hire a licensed electrical contractor to connect you.
What Happens To The Solar Panels If I Move Out
If you get solar panels installed and later decide to move home, you cant take the panels, smart export guarantee or feed-in tariff payments with you.
Solar payments are paid to the owner of the property where the solar panels are installed, so normally when you move, the new owner will receive the payments.
While you could physically remove the panels from your old home and install them on the new one, you still wouldnt receive payments, as the panels would be considered second-hand and so not eligible for the scheme.
Its also worth noting solar panel installations are tailored to each home to fit the roof and be positioned to maximise the level of sunlight they receive so its likely they wouldnt perform as well if you installed them on a different home.

Calculating Solar Power Costs
Once the above costs and benefits are determined, a solar system can theoretically be evaluated using the discounted cash flow method. Outflows at the beginning of the project would consist of installation costs , and inflows would arrive later in the form of offset electricity costs .
Rather than using DCF, the viability of solar power is usually evaluated by calculating the levelized cost of electricity , then comparing it to the cost of electricity charged by the local utility. The LCOE for household solar will typically be calculated as cost/kilowatt-hour the same format commonly used on electricity bills. To approximate the LCOE, one can use the following equation:
LCOE = Net Present Value of the Lifetime Cost of Ownership / Lifetime Energy Output
The useful life of a PV solar module is generally assumed to be 25-40 years. The cost of ownership includes the maintenance costs, which must be discounted to find the NPV. The LCOE can then be compared to the cost of electricity from a utility remember, the relevant price is that which occurs during times at or near peak PV solar production.

Size And Shape Of Your Roof
This one is a double whammy. The contours of your roof impact both the number of solar panels youll need to generate the necessary energy for your home and the labor involved in installing them for maximum efficiency. For example, gabled roofs with high peaks create lots of nooks and crannies for shadows, and they can be difficult for solar installers to navigate.
Average Monthly Energy Usage
This is the big one, if were being honest. Your energy bill will determine the size of the solar system you need therefore the number of panels you will need. While the average U.S. residential solar system is in the 5-kilowatt range, your family might be especially thrifty, meaning you might need only 4 kW to power your 2,000 square foot home.6 On the other hand, if you have a large family that entertains often and has installed lots of amenities in that same 2,000 square foot home, you might need an 8 kW system and that will cost more.
Other Benefits Of Solar Power
Solar panels can be very liberating. The more youre able to power your home entirely with solar energy, the less you have to rely on energy suppliers. If you can capture all the power you need from the sun, youll be living a life of electricity independence.
Most importantly, youll avoid the price hikes that suppliers often impose on their customers.
In late 2021, around 15 million UK households were told their annual energy bills would increase by £139 to £1,277 per year, as a result of Ofgem lifting its price cap.
These caps are revised every six months, which means that another increase might not be far away. Remember: the sun never increases its rates.
Additionally, a self-sufficient, solar-powered household will avoid any power cuts that hit the National Grid. Since Brexit took effect in 2020, the UK has narrowly avoided blackouts on multiple occasions, as Bloomberg has reported.
60% of the UK’s imported gas comes from the EU and Norway, and 91% of our imported electricity comes from the EU. Brexit has made the nation more vulnerable to supply shortages.

When Might You Pay Less Than 5300
On the other hand, if everything is in your favour, you may pay as little as £4,800 for a 4 to 4.5 kWp system.
Conditions conducive to a low price include:
- Bungalows with easy roof access, meaning scaffolding costs are lower.
- A big roof allows you to use lower capacity panels which are cheaper.
- Concrete tiles are easier and cheaper to install on than slate or clay tiles.
If you can then find a local installer who is fair and reasonable with their pricing, you are on to a winner.
Beware, though, if the price is too low, lets say close to £4,000. It may be the installer is cutting corners to get the price down that low.

How Much Do Solar Panel Systems Cost
There are many factors when looking at the cost of solar panels. These include: the type of solar panels installed, the size of the system, your type of property and which way the roof faces, and maybe more obviously the quality of the panels and components used.
Over recent years the solar industry has grown and changed, and as a result solar panels have become much more affordable. The savings on your electricity bill alone are an attractive reason to consider solar energy, but regardless of cost and money made, they are a great source of renewable energy and will undoubtedly lower your carbon footprint.
Solar panels will always be a long-term investment and the initial solar panel costs can seem high however the price of solar is now 70% cheaper than previous years.
Government incentives, schemes and support for this industry have now all ended but the price of a system is now far more affordable .
Electricity and gas bills will only ever go up now so a solar panel system for your home or business will help insulate you from these rising costs that are completely outside your control.

Examining The Recent Growth Of The Solar Energy Industry
The solar energy industry has experienced unprecedented growth in just the past 10 years. Why? Its all thanks to the Solar Investment Tax Credit a federal policy enacted in 2006 that offers discounts to homeowners, business owners and utility-scale solar generators who want to install solar panels either on their roof or on the ground like a solar farm.1 Since then, the industry has experienced an average annual growth rate of 42% and has created tens of thousands of jobs. In fact, according to the Solar Energy Industries Association:
- More than 100 gigawatts of solar capacity installed across the U.S. as of 2021 which is enough power to light 18.6 million homes.
- More than 230,000 Americans at more than 10,000 companies are employed by the solar industry.
- The cost of solar systems has dropped by more than 70% over the last decade.
- Prices as of Q4 2020 are at their lowest levels in history.7
Even better, as prices decrease for consumers, the quality, durability, and efficiency of PV technology increase. Its the ultimate win-win scenario, and its one that deserves a critical examination so homeowners can be educated on exactly how they can benefit from getting a solar power system installed on their homes.
Keep An Eye On Trade Policy
Changes in government trade policy also impact prices. In January 2018, President Trump imposed a four-year tariff on imported solar cells and panels that started at 30% and was set to drop 5% each year until February 2022. In 2020, the tariff rate for the fourth year was raised from 15% to 18%. The tariff resulted in a 16 cent per watt increase for the average consumer in 2018, which translated to an overall increase of $960 for a six-kW system, according to EnergySage.
The cost of foreign-manufactured panels may still drop, lessening the tariffs effect over time.

Implication Onto Electricity Bill Management And Energy Investment
There is no silver bullet in electricity or energy demand and bill management, because customers have different specific situations, e.g. different comfort/convenience needs, different electricity tariffs, or different usage patterns. Electricity tariff may have a few elements, such as daily access and metering charge, energy charge or peak demand charge . PV is a promising option for reducing energy charge when electricity price is reasonably high and continuously increasing, such as in Australia and Germany. However, for sites with peak demand charge in place, PV may be less attractive if peak demands mostly occur in the late afternoon to early evening, for example residential communities. Overall, energy investment is largely an economical decision and it is better to make investment decisions based on systematical evaluation of options in operational improvement, energy efficiency, onsite generation and energy storage.
Calculate Your Projected Energy Spending
Utilizing the amount of energy you consume on average and the average cost of energy per kilowatt in your area, calculate how much you will spend on normal electricity within the next 25 years. This is the typical lifespan of a solar panel array with minimal maintenance involved. When you make these calculations, be sure to account for utility cost inflation. You can make the assumption that your electric bill will increase by 2.2% per year.

Economics Of Solar Energy
The above graph shows the dollar value installed cost of solar panels for various capacity systems. Note the logarithmic scale on both the X- and Y-axis. This is the combination of the Residential and Commercial cost of solar power system graphs shown previously.
If youre going to invest in solar power, you want to know what your financial outcomes are going to be such as how much money you will earn from the solar panels and what the payback of the investment will be.
These terms can be a little deceiving since what is truly desired is whether it will save you money relative to continually renting electricity from the grid. We recommend not focusing solely on the payback period of solar panels, but analyzing the economics over 30 years since that is the period of the investment.
Levelized Cost of Electricity
A method used to calculate the economics of solar power in Alberta is called the Levelized Cost of Electricity or LCOE.
The LCOE is a good metric assess long term economics since this approach considers the total lifetime of the solar power system.
Mathematically, it is represented by the following equation :
Calculating the LCOE for a solar power system is not overly complicated. There are a few factors involved:
1. Installation Cost One-time lump sum provided by the solar contracting company
3. Lifetime energy output Annual energy output will be provided by your solar contractor. Remember that the system will degrade by~0.5%/yr.
Future of Electricity
Is Solar Getting Cheaper And Should I Wait
Solar is getting cheaper as every year passes due to the large spike in Chinese production, and market hyper-consumption. This along with the Australian governments Small-scale Renewable Energy Scheme has meant that installers have struggled to keep up with the demand of the last few years, and for good reason.
Should you wait? Not really. With the cost of power steadily on the rise in Australia and the interest-free finance available specifically for solar installs, there is no reason why you should not get a solar system installed taking advantage now of this far cheaper form of energy production.

Cost Of Solar Panel Maintenance
In general, solar systems are designed to run smoothly for decades without requiring much maintenance or upkeep. However, even the best systems require routine solar panel cleaning and checkups as grime, dirt and debris can accumulate over the solar cells.
Any sizable costs associated with malfunctioning panels should be covered by your panels warranty, but its not a bad idea to factor in the costs of a simple few cleanings and occasional maintenance.
Get Paid For Your Solar Panels’ Electricity
Some energy companies will pay you for electricity generated by your solar panels that you don’t use but put into the grid instead. This is called the Smart Export Guarantee .
You won’t get it automatically when you export electricity you’re not using. You’ll need to sign up with an energy company.
Find out about the Smart Export Guarantee explained, including how much you could earn and which companies offer it.
The SEG replaces the governments Feed-in Tariff scheme, which closed in March 2019. If you’re already signed up to it, read our guide to the Feed-in Tariff.

Considering that electricity is frequently cited as one of the priciest monthly utility expenses, it’s little wonder that solar panel installation is an intriguing proposition for many.
Finance Options For Solar Panels
There are a number of companies offering finance for solar technology in the United Kingdom. Finance, in the form of loans and leasing agreements, is available for domestic, commercial and industrial installations, in both the private and public sectors. Finance for renewable energy technologies allows customers to avoid large upfront costs and make payments out of the income from any Feed-in tariffs, as well as energy bill savings.
Finance may be offered on a range of bases, each offering varying levels of financial risk and reward, as well as varying interest rates. Typically, the finance company will provide the money to fund the cost of installation in return for payments spread over a period of time. Depending on the type of agreement, the client will most likely own the technology from the outset.
The arrangements offered by finance companies will vary, and each company will offer different advice. It is therefore advisable to obtain quotes and agreement terms from a range of companies. They should be based on clients energy needs and financial situation. Caution should also be taken when calculating ones ability to make repayments, as the returns offered by some renewable technologies depend in large part on the weather. Remember that if using finance arrangements this may impact on your future benefits and savings from having the solar panels and this should be carefully considered.
