01| Rising Electric Costs
The electricity prices in the UK have continuously been above the inflation rate, which is why investing in solar energy is an important idea. Although they have flattened, they remain above the pre-crisis level; thus, While installing your 12 kW system can help reduce your energy costs, you’ll still need to draw power from the grid during periods of lower generation, and a standing charge will apply.
02 | Smart Export Guarantee (SEG)
The SEG scheme enables you to earn a dollar based on the kilowatt-hour you can export into the grid from your 12 kW solar system. Newly, it ranges as high as 15p per KWH, which, when maxed, could trickle in around £918 a year on average for a 12-kilowatt solar system. Companies such as Octopus Energy can provide this rate.
03 | Direct Electricity Savings
The significant advantage of having a 12 kW solar system is that you can use the power produced for your home, thus minimizing the power you draw from the grid. Hence, one is likely to save by using the energy from the solar installation instead of procuring the electricity from the grid, which would cost £1,702 a year.
04 | 12 kW Solar System Price and Investment
The 12 kW solar system price in the UK is approximately £15,000, including installation and VAT. This upfront investment can be recouped through savings on electricity bills and earnings from the SEG, ensuring a quick payback period.
05 | Solar Panel Requirements
Modern solar panels typically range between 300W and 500W each. For a 12 kW solar system, you would need between 24 and 44 panels, depending on their wattage.
06 | Space Requirements
Each solar panel covers about 1.6 square meters. Thus, a 12 kW solar system would require between 39 and 72 square meters of roof space, based on the panels’ efficiency.
07 | Energy Production
A 12 kW solar system can generate about 11,122 units a year. 26 kWh a year in the United Kingdom. This output depends on the shading, the location of the building, the orientation of the roof, the time of the year, and the fineness of the components of the system.
08 | Off-Grid Considerations
Determining the battery storage capacity is essential if you are planning for an off-grid system. A 12 kW solar power system ranges between 24 to 44 solar panels, while the battery’s size depends on the house’s voltage draw.
09 | Why Choose a 12 kW Solar System?
A 12 kW solar system suits big or big consumption households or business establishments. It effectively cuts the electricity expenses and the quantity of carbon emissions and permits you to generate income through the SEG by selling back energy to the grid. Though one has to incur an initial 12 kW solar system cost, in the long term, there is always a chance to save costs and, at the same time, protect the environment.
10 | Cost and Payback Period
The 12 kW solar system cost in the UK is between £12,000 and £13,000, including VAT. Owing to the high energy output level, the rate of return on investment is among the fastest, making this system a financially sound decision, particularly for users with high energy requirements.
i.) Cost and Payback Period
The 12 kW solar system cost in the UK is between £12,000 and £13,000, including VAT. Owing to the high energy output level, the savings are among the highest, making this system a financially sound decision, particularly for users with high energy requirements.
ii.) Daily and Monthly Production
A 12 kW solar system can produce between 30 and 66 kWh daily, 900 to 2,000 kWh monthly, and 10,800 to 24,000 kWh annually. This output far exceeds the typical UK household’s annual consumption of about 2,900 kWh, providing ample energy for most residential needs.
iii.) Maximizing Efficiency
To achieve maximum efficiency, it’s essential to consider factors such as the direction and angle of your roof and the quality of the solar panels. Optimal performance is achieved with unobstructed, south-facing panels. While weather and shading can affect efficiency, a well-planned system can significantly reduce these impacts.
iv.) Solar Battery Options
To get even more benefits from your 12 kW solar system, it is recommended to include a solar battery. This addition can also benefit because the excess energy produced can be stored at another time, further moving away from the grid. The solar panels and battery cost between £2,500 and £10,000 extra, depending on size and capacity.
11 | Choosing the Right System
To invest in a 12 kW solar PV system, a certain amount of selection and comparison between various possibilities must be made. Solar4Good can help by directing you to experienced and skilled solar panel installers who will give you their recommendations and estimates. This assistance enables clients to contrast various suppliers and engage the most appropriate one for a particular service.
This makes the 12 kW solar system efficient in terms of savings and has a friendly environmental impact. Subsequently, the installation enables electricity generation and precise implementation of permits to decrease energy bills, earn money through SEG, and reduce carbon footprint. If one is to factor in every aspect and the various possibilities, a 12 kW solar system can be an excellent investment for homes and businesses.
