What Happens At Night Or When It Is Cloudy Outside
Depending on how cloudy it is, solar energy from the sun can still be collected on cloudy days. With net metering policies excess power that your system produced is virtually stored or credited to you to use at times when you are consuming more power than your system is using . No matter what time of day or the weather outside you can rest assured that you will always have reliable power provided to your home when you need it.
How Much Does A Typical Residential Solar Electric System Cost
A number of factors determine the final price of a PV system, including its size, component options and configuration, labor costs, local permitting costs and available incentives and tax credits.
The cost of a solar electric system is measured in dollars per watt. The average cost for a residential system is currently $3-5 per watt. That means the average 5-kW residential system will cost $15,000-$25,000, prior to tax credits or incentives.
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.

Review Your Electric Bill
Solar panels generate their own power and can therefore greatly offset your monthly electricity bill, if not eliminate it. The higher your bill, the more likely you’ll benefit from switching. But you should note that electricity rates and usage the main charges on your statement are volatile.
“If a utilitys electricity prices fluctuate, so could the amount of savings,” says Garrett Nilsen, deputy director for the U.S. Department of Energy’s solar energy technologies office. “Similarly, if energy consumption changes, the amount of savings can also vary.”
Visit the EIA website to view the most recent prices per state.
Additional Solar System Cost Variables
Its hard to dictate how much the additional costs of solar systems will be because they are changing variables. For instance, labor costs for solar installation vary depending on the area you live in.
Other solar system cost variables include solar mounts and solar inverters. There are different options for solar mounting but you will need this feature to hold your residential solar panels.
A solar inverter is necessary to transform your direct current power to the alternating current that you can start using in your home.
Your city or state might require you to get local permits that require a fee. Inspection fees might also be necessary.
The silver lining is that all of these costs go down if your state or city offers solar rebates and incentives. A good percentage of the cost for the different types of solar panels will be lower if this is the case.

Going Off The Grid With Solar Panels In South Africa
This system he uses is a 4.8KW Peak with storage.
The most cost effective way to go off the grid would be to replace stoves, ovens, geysers and even fridge/freezers with gas units, then your off the grid system will only need to power small appliances, electronics and lights making the size of you PV system smaller and cheaper.To try and run you entire house off solar is possible but very expensive and you would be paying more per KW than from grid power over the lifespan of your system and you would periodically need to replace those expensive batteries.
Mixed Dc And Ac System
A mixed DC and AC system can be used if you have more electrical needs than a DC system can handle but do not want a fully involved system. With this system, you can use fewer panels and batteries to power more heavy-duty appliances than a stand-alone DC system. This system is designed for low energy usage, but you still have batteries to provide electricity when the sun is not out. With this system, you still need a backup system. Expect to pay between $10,000 and $50,000, depending on the system size you need.

Solar Panels Are Generally Low Maintenance
The Energy Saving Trust says little maintenance is required on a properly installed, well-designed solar PV system, though you’ll likely need to replace the inverter a gadget which is a key part of the mechanism within about 25 years .
Of course, though, things can go wrong. If so, check the installer warranty you get it can cover you for up to 20 yeas. If the panels are damaged by something unexpected, like a storm, you may also be covered by buildings insurance check with your insurer before you have them installed.
Feed In Tariff Scheme:
As of the 31st of March 2019 the feed in tariff no longer exists. Currently, you can make money from any unused electricity by selling it back to the National Grid.
Now that the Feed in Tariff has ended there are two other options:
The first is a battery which will store the unused electricity and means that you can run off grid depending on the amount you collect and use.
The second is the Smart Export Guarantee introduced by the government which means that energy suppliers will compete to give households the best price for their excess electricity. Homeowners will still see a long-term payment and faster return on their investments.
It is true that solar panels will never be cheap, but never the less, they are a good investment. Annually you can expect to save between £85 to £500+ on your energy bills depending on how much power you use daily and how many people live in your household. Those eligible for the FIT payments will save more money every year for 20 years. Even without FIT payments or when the payments end the power produced by your solar set up will be free.
Old feed in tariff rates:
If you were lucky enough to sign up before the 31st of March 2019 you would have received these payments. If you have a property which has an EPC of D or above, the FIT rate was 3.79p at scheme end. You can find the rates on the Ofgem website.
Once receiving the FIT, you would have continued to receive it for 20 years.

How Much Does Regional Climate Affect Solar Panel Installation Costs
The table below shows how much electricity 1 kW of solar panels installed on a southern-facing roof will produce, on average, in the following states:
You can find out how much is produced in the other states, and even down to your specific house, by using this solar power generation calculator.
Annual solar panel production per state
As you can see, solar panels installed in the northeast will produce approximately 35% less power than solar panels installed in sunnier places, like Arizona. Solar panels in Arizona generate more electricity because the sun is typically always shining.
So, a home in Arizona that is using the same amount of electricity as a home in Massachusetts will need a system thats 35% smaller, simply because Arizona gets more sunshine.
Evaluate Your Sunlight Exposure
More sun means more energy produced and a greater potential to save with solar. Certain states, like Arizona and California, average more sunlight hours per day.
Your home’s orientation toward the sun, the amount of shade and its roof type also affect a solar system’s output. You can estimate the efficiency of panels in your area by using the SolarReviews calculator. Enter your address and the average cost of your monthly energy bill.

How Do You Pay For A Solar Panel Installation
Once you know the cost of solar for your unique project, its time to decide how youll pay for solar. There are three primary ways to finance a solar panel installation: a cash purchase, a solar loan, or a solar lease/power purchase agreement.
Generally, a cash purchase is right for you if youre looking to maximize your savings from solar, you have enough tax liability to take advantage of the solar tax credit, or you have the funds available to pay for a solar panel system upfront.
A solar loan is right for you if you dont want to shell out the amount of cash required to pay for a solar panel system upfront, you still want the most savings on your electricity bills as possible, and you would like to be eligible for all incentives and rebates.
A solar lease or PPA is right for you if you would prefer someone else to monitor and maintain the system, if you arent eligible for tax incentives, or if youd just like to reduce and/or lock-in your monthly electricity bill.
The Cost Of Installing A Solar System
There are many incentives available for solar owners. These need to be considered when examining the cost of a solar system.
Those incentives include:
- Reduced monthly electric bills
- Protection from rising energy rates and independence from your utility company
- The 26% tax credit which can be used to recover prior year taxes and also carried forward 20 years for businesses and 5 years for homeowners
- Businesses and farms can quickly recover their investment through accelerated depreciation. Those who qualify can apply for a USDA Reap Grant and other local grants
- Its sustainable and good for the environment
With that in mind, below weve listed the average installation cost for commercial and residential solar energy systems.

What Is The Difference Between A Lease And Power Purchase Agreement
When solar was first introduced, homeowners had no other option to spend money upfront to add solar to their home. Recent developments in available incentives and changes in utility rules now allow for a third party to purchase the system on your roof and provide you with the power produced by the system. Both a lease and a PPA operate in a similar fashion in that your monthly payment for the electricity is replaced by a lower monthly payment for the solar system. In both cases the maintenance and repairs of the system are covered at no cost to you.
A lease system is very similar to the way you would lease a car. You receive the system at no upfront cost with the agreement that you will pay a fixed monthly amount for a designated amount of time. That rate is agreed upon in advance no matter how much electricity is produced by the system. The amount of your lease payment should be lower than your current average monthly electricity bill. In a Power Purchase Agreement the amount you pay every month is determined by the amount of power the system produces. The amount of system your power produces is determined by the amount of sun it receives in that month.

When there is no sunlight on the panel you use municipal power.Off Grid Solar energy Most Off Grid systems will need storage for power when there is too little or no sunlight to produce the power you need, unless you have specific applications, like solar borehole pumps or pool pumps, that only need to work when there is sufficient sunlight.Hybrid Solar energy systemsMost residential installations in South Africa use hybrid inverters where the solar panels will produce all or part of the energy requirements for the household during the day and use grid power at night. When the panels are not producing enough power,in this setup, for example if there is a general power failure, the inverters will turn off, cutting off all power. Batteries can be added on to provide backup power during load shedding or general power outages.
