Things You Need to Consider Before Installing Solar PV

Over the past few years, solar power technology has seen some incredible advancements. Many UK households are now opting for solar energy systems as a way to cut down on their electricity costs and reduce their environmental impact. By installing solar PV panels, you can generate renewable energy to power your home or business while also contributing to a greener planet.

However, before you take the plunge and install a solar panel system, there are several important factors you need to consider. This guide will walk you through the key considerations you should keep in mind before installing your solar panel system.

Key Takeaways

• Before installing solar panels, check the strength of your roof to ensure it can support the weight of the panels, and reinforce it if necessary.
• Select the appropriate type of solar panels, as their quality directly affects the efficiency and lifespan of your PV system.
• Invest in a high-quality inverter, as this device is often the limiting factor in your solar installation and plays a critical role in its performance.

Key Considerations Before Solar Panel Installation

With the decreasing cost of solar panels, many businesses and homes are turning to solar power. By reducing reliance on grid electricity and increasing self-generated solar power, you can save money on your electricity bills or even go completely off-grid.

Wondering how to install solar panels for your home or business?

A professional solar installer can handle this for you easily. However, you need to understand what you're getting into to ensure you're investing in a worthwhile installation. Here are the factors you should consider before installing solar panels.

Roof Strength

Not all buildings, especially older ones, have roofs that are strong enough to support solar panels. Buildings constructed after 1970 often feature 'W' framed trussed roofs. Solar panels typically weigh around 20 kg each, and they can easily handle the weight of multiple panels.

While adding cross strengtheners isn't an overly expensive process, it may be necessary for older buildings. Every roof should be inspected, as it may contain termites or woodworms, which can significantly weaken its structure.

Several solar companies offer free roof assessments to determine if your roof is suitable for solar panels.

Types of Solar Panels

Various solar energy systems are available in the market. While photovoltaic systems can generate electricity, solar thermal systems are used solely for heating water.

The two most common types of solar energy systems are monocrystalline silicon panels and polycrystalline silicon panels. Although monocrystalline silicon panels tend to offer slightly higher efficiency than polycrystalline, other factors often outweigh this advantage.

The quality of the solar panels you use greatly influences the output of your PV system. Once installed, a solar PV system can last up to 25 years. Thus, selecting a system from reputable solar companies will ensure smooth operation and minimal maintenance.

Inverter Requirements

Your solar PV system consists of more than just solar panels; it also includes an inverter. Choosing a high-quality inverter is essential since these devices are often the limiting factor in any solar installation. In most cases, the inverter is the first component in the setup that requires replacement.

The lifespan of an inverter typically ranges from 10 to 15 years. If you're torn between spending more on a high-quality solar panel or a premium inverter, it's usually better to invest in the inverter.

Energy Use

When you choose a qualified solar installer, they will help you track your energy usage. This is crucial in determining the desired output of the solar installation. Understanding your typical energy consumption can help you decide how many solar panels to install and what percentage of your energy needs can be met by solar energy.

Financial Incentives

People interested in setting up solar panels may qualify for financial incentives from the UK government. These incentives aim to make solar-generated electricity competitive with other forms of energy production.

These subsidies can take various forms. The two main types are:

• Investment subsidies, where part of the cost of solar panel installation is partially reimbursed.
• Feed-in tariffs/net metering, which allow you to sell the solar power you generate back to the utility company operating the grid. Here, your panels are connected to the consumer unit, allowing you to earn money from the extra energy produced while reducing your electricity bills.

When deciding if it makes financial sense to install solar panels on your home or business, one of the most important factors to consider is whether your community offers any financial incentives.

Assessing Your Needs

Power outages are relatively rare in the UK. However, if you have solar panels, don't rely on them to power your house during a blackout. Most solar power systems are connected to the grid using a grid-tied inverter.

Grid operators must shut down the grid for necessary repairs if a blackout occurs. Therefore, even though solar panels are a great investment, you shouldn't count on them to save you in a power outage.

If you want to protect yourself against power outages, you must invest in a battery backup system.

Solar Battery

Most households only use solar panels during the morning and evening, when the sun is shining brightest. However, this doesn't always align with peak power usage, which typically occurs in the evening after the sun has set.

Therefore, it makes both economic and environmental sense to charge a solar battery during the day and consume the stored energy later. This approach allows you to make full use of your solar energy throughout the day and night.

Professional Installer

Once you fully understand the issues outlined above, it's time to select a solar installer. A professional will guide you in the following ways:

• Evaluate your needs
• Help you find the best installation and setup options
• Ensure proper planning permission and paperwork are obtained
• Carry out the installation and make necessary connections

Importantly, installation must be performed by trained professionals. If you hire a service, make sure it's one you can trust.

Case Study: Comprehensive Pre-Installation Assessment for Solar PV System

Background

At Solar Panels Network, we prioritize offering custom solar solutions tailored to our clients' specific needs. This case study highlights the comprehensive pre-installation assessment conducted for a residential property looking to transition to solar energy. Our goal was to ensure a smooth installation process while maximising the system's efficiency and longevity.

Project Overview

The homeowners, living in a suburban area with a mix of modern and older properties, were eager to reduce their energy costs and carbon footprint. They sought a reliable and efficient solar PV system that could meet their daily energy needs while also providing a buffer during peak usage times. Our task was to evaluate the property's suitability for solar panels and design a system that aligned with their energy requirements.

Implementation

To achieve the desired outcome, we took the following steps:

Roof Strength Assessment: Conducted a thorough inspection of the roof's structure to ensure it could support the weight of the solar panels. We identified the need for minor reinforcements due to the building's age.

Selection of Solar Panels and Inverter: Chose high-efficiency monocrystalline silicon panels for their superior performance. Paired these with a premium-grade inverter to optimise energy conversion and system reliability.

Energy Consumption Analysis: Analysed the homeowners' electricity bills and usage patterns to accurately size the solar PV system. This data helped determine the number of panels required and the potential savings.

Financial Incentives and Options: Advised the homeowners on available financial incentives, including the Smart Export Guarantee (SEG) and potential tax benefits, to maximise their investment returns.

Solar Battery Integration: Recommended the inclusion of a lithium-ion battery to store excess energy generated during the day, ensuring a steady power supply during peak evening hours.
