How Renewable Energy Could Reduce Costly Bills
As current high energy prices continue to dominate discussions throughout Britain, renewable energy solutions such as rooftop solar panels are becoming increasingly popular. However, for those who are hoping for larger returns from such investments, it is important to note this may not be the case. Instead, the merits of such investments largely rely on the carbon savings they provide.
While renewable energy commitments are high, those who look to invest in them cannot simply rely on high dividends to justify their stance; this is especially true if and when electricity prices return to historic levels. For example, a 4KW array in the UK would have to offset 700 kg of CO2, or 84% of a home’s annual energy related carbon footprint, according to Lex estimates.
Let’s take a closer look at the numbers and expected returns. At an average cost of £1,800/KW, 4kW of solar panels would produce roughly £7,200 in revenue. However, in areas known for cloud coverage, such solar panels would only be able to generate electricity around 1,000 hours per year, or roughly 11% of the time, providing 4,000 KWh of energy per year for 25 years.
The Benefits of Renewable Energy and Rooftop Solar Panels: Who Stands to Gain?
While renewable energy sources are good for the environment, not all of the electricity produced by the panels would be used by the homeowner. As such, they can expect their bill to decrease significantly in the beginning. However, energy is typically produced during the day, when it is not in use, rather than at night when families tend to use the bulk of their electricity.
For instance, let’s say that only 35% of the electricity produced by the solar panels is actually used by the homeowner. If this were the case, then their yearly bill would decrease from £1,063 to £640 – resulting in a total saving of £423. By 2030, however, energy prices may drop back to what they were before the crisis, which will gradually reduce the amount of yearly savings to £280.
This issue is compounded by the fact that energy that is not used would be sold back to the network. However, there are vast differences in prices from supplier to supplier. While homeowners would benefit from this, it is important to note that such profits tend to be much lower than their initial investment over time. A reasonable estimate for such earnings this year may be around £300, which may decrease to £200 over the years.
What is the True Value of Solar Panels for Homeowners and Small Business Owners?
If you add up the annual savings and income from the network and discount it by 5%, you get just under £8,000, leaving a net present value of less than £80 before any maintenance costs. For small businesses or those who rely on energy from solar panels, the numbers look much more favourable. However, for the average homeowner, it may not be enough to justify the initial costs, with environmental benefits being the main reward.
It is clear that renewable energy is not always the best decision for everyone. As such, it is important to assess the real benefits of such an investment for your home or business before going ahead with it.
Summary
This article discusses renewable energies, with a focus on the often-debated topic of rooftop solar panels. While these renewable energy options are popular, the real benefits of them may not be as large as some expect. Those considering such investments must keep in mind that the merits and rewards of renewable energy investments are mostly related to carbon savings. For example, a 4KW array in the UK would have to offset 700 kg of CO2, or 84% of a home’s annual energy related carbon footprint, according to Lex estimates. The article also gives an overview of the numbers involved in generating energy from solar panels, including the amount of electricity produced during operating hours and the sale of excess energy to the network. Additionally, it presents the math behind how much a typical homeowner can expect to save with solar panels in the short and long-term.
Additional Piece
While renewable energy sources continue to be a hot topic, the reality is that for some homeowners, the cost of installation may outweigh the benefits. As such, it is important to weigh the different factors involved and decide if renewable energy is the right choice for your home. Many businesses, on the other hand, could stand to benefit a great deal from such investments. Here are a few points to consider:
1) Environmental Benefits
The environmental benefits of renewable energies are unparalleled. By installing renewable energy sources in your home or business, you can make your carbon footprint much smaller while reducing your reliance on non-renewable energy sources. For businesses, this can be especially important as it offers a chance to show customers that your business practices are eco-friendly and ethical.
2) Cost
While renewable energy is, in many cases, cheaper in the long run, the upfront installation costs can be quite high. It is important to assess the potential savings and compare these figures to the initial installation costs before making a decision to invest – especially for homeowners. However, for businesses, such investments are essential, since it can result in a positive impact on the bottom line.
3) Efficiency
Renewable energy sources such as solar panels can be highly efficient, depending on their intended use. While not all electricity produced may be used, it can be a valuable addition to your energy supply, contributing to significant cost savings.
4) Government Incentives
Many governments offer incentives to homes and businesses that use renewable energy sources, such as tax credits or refunds. By capitalising on such incentives, you can reduce the overall cost of installation and limit your financial risks associated with the investment.
Renewable energy is not for everyone. However, for those who want to reduce their carbon footprint and save money on their energy bills, it can be a wise investment. Be sure to get an accurate assessment of the initial investment costs and long-term savings to determine if this option is viable for your home or business.
Summary:
The article discusses the costs and benefits associated with investing in renewable energies such as solar panels. While such investments offer a great deal of value in terms of reducing one’s carbon footprint, the initial costs of installing these renewable energy sources can be quite steep. Applicable for both homeowners and businesses, it is important to assess the potential benefits to determine if such investments are worthwhile.

Current high energy prices – and how to reduce them – have been the subject of cooler conversations far and wide in Britain. So it should come as no surprise that the idea of installing rooftop solar panels is making a comeback. But those who consider renewable energies so high should not count on large returns.
If electricity prices were to return to historic levels, the merits of this investment would be almost entirely due to the carbon savings. For a 4KW array in the UK, Lex estimates those have to be 700kg of CO₂, or 84% of a home’s annual energy-related carbon footprint.
Take a look at the numbers involved. At an average cost of £1,800/KW, 4kW of solar panels would earn £7,200. In these cloud islands, these would produce electricity about 1,000 hours per year, or 11% of the time, providing 4,000 KWh of domestically produced energy per year for 25 years.
The problem is that not all of this would be used by those living under the paneled roof. The sun produces electricity during the central hours of the day, while families tend to turn on their kettles and televisions during the night.
Suppose 35% of the electricity from the solar panels was consumed internally. This would reduce this year’s bill from £1,063 to £640, for the average home, or a saving of £423. By 2030, however, electricity prices could be back to what they were before the crisis, reducing gradually the annual savings to £280.
Energy that is not consumed would not be wasted, of course. It would be resold to the network. Different suppliers offer different prices for it, but these tend to be at a huge discount to the retail cost. A reasonable estimate for this earnings stream could be £300 this year, declining to £200 over time.
If you add up the annual savings and income from the network and discount it by 5%, you get just under £8,000, which leaves a net present value of less than £80 before any maintenance costs. For a small business, which uses energy from solar panels, the numbers look better. But for the average homeowner, it all seems a bit wash, albeit with environmental benefits.
