What Are Watts And Kilowatts
To understand how much electricity a solar panel can produce, we first need to get comfortable with some units of power and energy.
If youve been reading about solar panels, youll have noticed some specific units being mentioned: watt and kilowatt , plus watt-hours and kilowatt-hours . Watt and kilowatt are units of power, and indicate how much power a solar panel can provide 1,000 watts = 1 kilowatt .
Watt-hour and kilowatt-hour are units of energy, and are used to show how much work can be completed in one hour 1,000 watt-hours = 1 kilowatt-hour .
How Do Seg Tariffs Work
Energy suppliers can decide the rate they pay, the length of the contract, and whether tariffs are fixed or variable. Fixed SEG tariffs pay a set rate per kilowatt hour of electricity exported over the length of the contract.
A variable tariff will have fluctuating prices depending on market demand . It therefore pays to shop around and compare what is on offer.
Note that you cannot receive both a feed-in tariff and SEG payments, but you can opt out of the feed-in tariff scheme if you would prefer to receive SEG payments.
What Are The Labour Costs
When you are given a quote for your solar panel system, labour costs are typically included. There are two common ways of calculating the labour costs for solar panel installations in the UK.
One way is to calculate approximately £300-£500 per person, per day. As it usually requires two people to install the system, a final installation fee is normally £600-£1,000. If you are installing a larger system, it may take more than one day and the costs will naturally rise.
Another way to calculate the installation fee is to charge 20 pence per watt. So, for a 4kW system, you would be paying 20 pence for 4000 watts, resulting in £800.

Solar Power For The Home: Costs
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.
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.
While the above costs are relatively straightforwardoften a solar installation company can quote a price for these for a homeownerdetermining subsidies available from the government and/or your local utility can prove more of a challenge. Government incentives change often, but historically, the U.S. government has allowed a tax credit of up to 30% of the system’s cost.

Whats The Power Rating For An Average Solar Panel
The reason that residential solar panels are generally sold in the range of 260-330 watts is because of the simple practicality that they need to be lifted onto roofs and handled by installers and this is the largest practical size in which this handling can be done safely. These are panels containing 60 cells. There are also less commonly used solar panels that contain 72 cells and are sold in the wattage range of 340-400 watts but these panels become large and difficult for installers to handle.
How Much Will Your Electric Bill Be After Installing A Home Solar System
The truth is, it depends on a few aspects. Your solar installations energy production, your local electric rate, and your households energy consumption.
With optimized household energy consumption and a maximized home solar installation, you can develop a financial equation that balances your electric bill and energy needs. Then, add up the thousands of dollars youre not spending over the years by using home solar.
Plus, there are bonus points. Because of the costs you avoid in going solar, your benefits will be even greater in states with high electric rates.
And, as energy prices spiral upward, your financial security will become even more advantageous over the 25-year lifecycle of your home solar system. Take control with solar. Its your home, your energy.

Typically, a modern solar panel produces between 250 to 270 watts of peak power in controlled conditions. This is called the nameplate rating, and solar panel wattage varies based on the size and efficiency of your panel. There are plenty of solar calculators, and the brand of solar system you choose probably offers one. That said, there is a simple equation to calculate the amount of kilowatt-hours your solar panel system will produce.
So now that we know you need to produce about 6kW of AC output, we can work backwards to figure out how many solar panels you need. Solar panels produce direct current , and your home runs on alternating current .
Yep, like the band, AC/DC.
Because of physics, there are losses in converting the energy from the sun into DC power, and turning the DC power into AC power. This ratio of AC to DC is called the derate factor, and is typically about .8. This means you convert about 80% of the DC power into AC power.
This continues to improve ever so slightly, but the losses are unavoidable because of physics! So you take the AC amount you need: 6kW and divide by .8 . This means that youll need 30 250Wp solar panels or 27-28 270Wp panels.
Is It Sunny Enough For Solar Power To Be Generated In The Uk
Yes. While its true that the UK isn’t exactly bathed in sunshine, solar panels, despite their name, don’t need direct sunlight – they also work in cloudy or overcast weather.
Although. cloudy weather diminishes the generating capacity of panels by approximately 50% in comparison to direct sunlight, solar panels in the UK are still a valid means of producing electricity
How Long Do Solar Panels Take To Pay Themselves Off
On average, a solar panel system takes between 7 and 13 years to pay off. This depends on sunlight exposure and the national average electricity rate or even the electricity rate with your utility company. To calculate how much do solar panels take to pay off in your case, divide the price of going solar by annual savings.

Will The Quality Of My Electricity Suffer
No. You won’t notice any difference. If the panels aren’t producing much electricity, you’ll just use electricity from the Grid instead.
Solar panels don’t replace the energy you currently use, they simply supplement them with power from a greener source when possible. Conversely, if you generate too much solar power you can sell the energy back to the National Grid at an agreed rate through the Feed-in Tariff scheme.
Concentrating Solar Power Stations
Commercial concentrating solar power plants, also called “solar thermal power stations”, were first developed in the 1980s. The 377 MW Ivanpah Solar Power Facility, located in California’s Mojave Desert, is the world’s largest solar thermal power plant project. Other large CSP plants include the Solnova Solar Power Station , the Andasol solar power station , and Extresol Solar Power Station , all in Spain. The principal advantage of CSP is the ability to efficiently add thermal storage, allowing the dispatching of electricity over up to a 24-hour period. Since peak electricity demand typically occurs at about 5 pm, many CSP power plants use 3 to 5 hours of thermal storage.
