Comparing Domestic Energy Sources

As energy prices go up and down and sustainability becomes a growing priority, we’re talking to more and more homeowners in Derby and the surrounding areas about how they Heat and power their homes. From traditional grid electricity to renewable technologies like solar panels and battery storage, there are now more options than ever.

At P&C Electrical, we specialise in helping homeowners and businesses make informed decisions about their energy use and how to save money and the planet. In this article, we cover the main types of domestic energy sources and their pros and cons, We also explain why solar power is rapidly becoming the energy source of choice for many households in the East Midlands.

Electricity From The Grid

Most UK homes rely on electricity supplied via The National Grid. This energy is distributed around the country by overhead power lines and underground cables into our homes. It is generated from a sources including natural gas, nuclear, renewables including solar and wind and may even be imported from neighbouring countries.

Advantages:

1. Reliable and always available
2. No upfront installation costs
3. Simple set up, supply and billing
4. Network of engineers ready to make repairs

Disadvantages:

1. Rising and unpredictable energy costs
2. Prices can be affected by issues hundreds of miles away
3. High carbon footprint depending on the sources of energy
4. Often no control over how your energy has been generated although some providers now state that some or all of their energy comes from renewable sources

Grid electricity is still an essential part of our energy infrastructure but there are ways to add alternative electricity sources that give you much more control over the cost of your electricity.

Solar Panels For Renewable Electricity Generation

Solar photovoltaic (PV) panels mounted on the roofs of homes throughout Derbyshire generate electricity for those homes directly from the energy in sunlight. There is a difference in the amount of electrical energy that can be generated on a cloudy day compared to a bright, sunny day. However, solar panels still work in cloudy conditions. After all, the difference between a cloudy day and mid-night is literally night and day. There is a lot more light on the cloudiest day than there is in the middle of the night.

Advantages:

1. Significantly reduces electricity bills
2. Renewable and environmentally friendly
3. Low maintenance and long lifespan (25+ years)
4. You will be eligible for the Smart Export Guarantee where you actually earn money when the system sends any excess energy it has generated back into the grid.

Disadvantages:

1. Initial installation cost
2. Output varies with weather and daylight hours so you need something to store excess energy to release during times of low generation and high use
3. You need enough roof space for the panels and it needs to be facing in the right direction to catch the sun.

Solar panels are one of the most accessible and cost-effective ways for homeowners to take control of their energy costs. They can also increase a property’s value and are easy to maintain and update. Nowadays, solar systems are controlled by smart apps to maximise energy generation and use of electricity from them and the grid. You can also integrate them with smart battery storage to smooth out energy generation spikes and troughs and to allow the system to send unused electricity back into the grid. Batteries can also store energy bought from the grid at low tariff prices such as overnight.

Battery Storage

Battery storage systems are typically installed alongside solar panels. They hold excess electricity generated during the day so it can be used in the evening or during peak tariff periods to save money.

Advantages:

1. Maximises use of your solar energy
2. Reduces your reliance on the grid
3. Protects against rising energy prices
4. Can provide backup power in some systems

Disadvantages:

1. Additional upfront investment
2. Limited storage capacity (depending on system size)

Battery storage is the key to unlocking true energy independence from solar panel systems and significantly improving the return on your investment.

Alternatives To Electric Heating

Gas

Gas is still widely used in UK homes, particularly for heating and hot water systems.

Advantages:

1. Gas is generally cheaper than electricity per kWh
2. It is efficient for central heating
3. There’s a well established infrastructure

Disadvantages:

1. Gas is a fossil fuel. Burning it to heat water for washing and in heating systems releases significant emissions of carbon in the shape of carbon dioxide into the atmoushpere
2. Gas prices are subject to global market fluctuations
3. Future restrictions are more likely as the UK moves toward net zero

Gas is effective for heating, but its long-term viability is uncertain as the UK transitions toward cleaner energy.

Air and Ground Source Heat Pumps

Heat pumps are an increasingly popular low-carbon alternative to gas boilers, using electricity to extract heat from the air.

Advantages:

1. Highly energy efficient
2. Lower carbon emissions
3. Eligible for government incentives

Disadvantages:

1. Higher installation cost than traditional boilers
2. Heat pumps work best in well-insulated homes
3. It may be necessary to upgrade radiators and add a hot water tank and associated pipework

When paired with solar panels, heat pumps can further reduce your home’s reliance on fossil fuels.

Comparing Your Options

When choosing the right energy setup for your home, it’s important to consider cost, sustainability, and long-term value.

1. Lowest upfront cost: Grid electricity and gas
2. Lowest running cost: Solar panels especially when installed with battery storage
3. Most environmentally friendly: Solar panels, storage batteries and heat pump heating combination
4. Best long-term investment: Solar panels with battery storage

Why More Derby Homeowners Are Choosing Solar

We’re seeing a movement towards solar energy systems in Derby and throughout the surrounding areas. While the price of electricity from the grid keeps increasing, constant technological improvements keep increasing the efficiency while reducing the cost of solar systems. Consequently, the return on investment has never been stronger. If you don’t want to miss out on the day-to-day savings of running your home on electricity generated on your roof, now’s the time to act.

A typical residential solar installation can:

1. Cut electricity bills by an amazing 50 to 70%
2. Pay for itself in six to ten years
3. Increase the value of your home
4. Significantly reduce your family’s carbon footprint

Add battery storage, and you can push those savings even further while gaining greater control over the cost ofyour electricity.
