Installing a 4kW System on your property

Back to all insights

In Northern Ireland, solar energy, albeit with its sporadic sunny days, is making its mark. If you’re considering hopping onto the solar bandwagon, here’s what you need to know about installing a 4kW system.

How much should a 4kW solar system cost?

In Northern Ireland, the cost of solar installations can vary based on several factors including the quality of the solar panels, installation charges, and potential add-ons or upgrades. On average, a 4kW solar system ranges from £5,000 to £8,000. It’s always a wise idea to gather multiple quotations and ensure that you’re receiving quality panels and service for your investment. Solar Power NI start their 4kW installations at just £4,999.

Is a 4kW solar system worth it?

The simple answer is, yes. Not only does a 4kW system contribute to a cleaner environment by reducing your carbon footprint, but it also brings about substantial savings in the long run. With energy prices on the rise, solar power provides a level of independence from the grid. Additionally, government initiatives and schemes might offer incentives for renewable energy installations.

Is 4kW enough to power a house?

A 4kW system is a mid-sized solar setup. On an average day with good sunlight, you can expect the system to generate around 16-18kWh. While this may not be sufficient to power a large home entirely, it’s substantial for an average-sized Northern Irish household, especially if paired with energy-saving habits.

With a 4kW system, you can comfortably power your lights, television, computer, fridge, and washing machine during sunny periods. In the darker winter months, you may need to rely more on the grid, especially during peak times. Nevertheless, during sunnier spells, it’s a significant source of energy.

How much roof space do I need?

Typically, you’d need about 20-28 square metres of roof space for a 4kW system. It’s crucial that this area is primarily south-facing to maximise sunlight absorption. Ensure there are minimal obstructions like chimneys or other buildings casting shadows for optimal efficiency.

How much can I save on my electricity bills with a 4kW system?

Savings are dependent on various factors: your energy consumption habits, the efficiency of your system, and the rate you’re paying for electricity. On average, a 4kW system in Northern Ireland could save you between £500 – £800 annually. When you factor in the potential rise in energy prices, these savings could increase over time.

How to maximise efficiency of your 4kW panels

Orientation & Tilt: South-facing panels at a tilt of about 30-40 degrees are ideal.

Regular Maintenance: Clean your panels regularly to remove dirt and debris. This ensures maximum sunlight absorption.

Efficient Appliances: Pair your system with energy-efficient appliances to get the most out of your generated energy.

Monitor & Assess: Use monitoring systems to check your energy production and consumption. Adjust habits if necessary.

Battery Storage: Consider investing in a good battery storage system. This allows you to store excess energy for use during periods when the sun isn’t shining.

In conclusion, installing a 4kW solar system in Northern Ireland is a practical, environmentally-friendly, and cost-effective step for many homeowners. The upfront cost may seem significant, but the long-term benefits, both environmentally and economically, are hard to overlook. Before taking the plunge, always conduct comprehensive research and engage with reputable solar providers to ensure you’re making a well-informed decision.
